-└── examples/                    # Example workspace configurations
-```
-
-### Why `src/` subdirectory
-
-This is the **standard mdBook convention**:
-- **Source (`src/`)**: Version-controlled markdown files, directly readable
-- **Output (`book/`)**: Generated HTML/CSS/JS, Git-ignored (regenerated on build)
-
-This separation allows the same source files to generate multiple output formats (HTML, PDF, EPUB) without
-cluttering the version-controlled repository.
-
----
-
-## 🔨 Building HTML with mdBook
-
-If you prefer a formatted HTML website with search, themes, and copy buttons, build with mdBook:
-
-### Prerequisites
-
-```bash
-cargo install mdbook
-```
-
-### Build & Serve
-
-```bash
-# Navigate to docs directory
-cd provisioning/docs
-
-# Build HTML to book/ directory
-mdbook build
-
-# Serve locally at http://localhost:3000 (with live reload)
-mdbook serve
-```
-
-### Output
-
-Generated HTML is available in `provisioning/docs/book/` after building.
-
-**Note**: mdBook is entirely optional. The markdown files in `src/` work perfectly fine in any Git
-viewer or text editor.
-
----
-
-## 📖 Reading Markdown Directly
-
-All documentation is standard GitHub Flavored Markdown. You can:
-
-- **GitHub/GitLab**: Click `provisioning/docs/src/` and browse directly
-- **Local Git**: Clone the repo and open any `.md` file in your editor
-- **Text Search**: Use `grep` or your editor's search to find topics across all markdown files
-- **mdBook (optional)**: Build HTML for formatted reading with search and theming

-<h2 id="executive-summary"><a class="header" href="#executive-summary">Executive Summary</a></h2>
-<p>This document clarifies <strong>how the Rust orchestrator integrates with Nushell core</strong> in both monorepo and multi-repo architectures. The orchestrator is
-a <strong>critical performance layer</strong> that coordinates Nushell business logic execution, solving deep call stack limitations while preserving all existing
-functionality.</p>

-<p><strong>Original Issue:</strong></p>
-<pre><code class="language-plaintext">Deep call stack in Nushell (template.nu:71)
-→ "Type not supported" errors
-→ Cannot handle complex nested workflows
-→ Performance bottlenecks with recursive calls
-</code></pre>
-<p><strong>Solution:</strong> Rust orchestrator provides:</p>
-<ol>
-<li><strong>Task queue management</strong> (file-based, reliable)</li>
-<li><strong>Priority scheduling</strong> (intelligent task ordering)</li>
-<li><strong>Deep call stack elimination</strong> (Rust handles recursion)</li>
-<li><strong>Performance optimization</strong> (async/await, parallel execution)</li>
-<li><strong>State management</strong> (workflow checkpointing)</li>

-5. HTTP POST → http://localhost:9090/workflows/servers/create

-<p>The orchestrator provides:</p>
-<ul>
-<li>Performance layer (async, parallel execution)</li>
-<li>Workflow engine (complex dependencies)</li>
-<li>State management (checkpoints, recovery)</li>
-<li>Task queue (reliable execution)</li>
-</ul>
-<p>While Nushell provides:</p>
-<ul>
-<li>Business logic (providers, taskservs, clusters)</li>
-<li>Template rendering (Jinja2 via nu_plugin_tera)</li>
-<li>Configuration management (KCL integration)</li>
-<li>User-facing scripting</li>

-<p>The provisioning project has been restructured to support a dual-organization approach:</p>
-<ul>
-<li><strong><code>src/</code></strong>: Development-focused structure with build tools, distribution system, and core components</li>
-<li><strong>Legacy directories</strong>: Preserved in their original locations for backward compatibility</li>
-<li><strong><code>workspace/</code></strong>: Development workspace with tools and runtime management</li>
-</ul>
-<p>This reorganization enables efficient development workflows while maintaining full backward compatibility with existing deployments.</p>

-## What is Provisioning
-
-**Provisioning** is a comprehensive **Infrastructure as Code (IaC)** platform designed to manage
-complete infrastructure lifecycles: cloud providers, infrastructure services, clusters,
-and isolated workspaces across multiple cloud/local environments.
-
-Extensible and customizable by design, it delivers type-safe, configuration-driven workflows
-with enterprise security (encrypted configuration, Cosmian KMS integration, Cedar policy engine,
-secrets management, authorization and permissions control, compliance checking, anomaly detection)
-and adaptable deployment modes (interactive UI, CLI automation, unattended CI/CD)
-suitable for any scale from development to production.
-
-### Technical Definition
-
-Declarative Infrastructure as Code (IaC) platform providing:
-
-- **Type-safe, configuration-driven workflows** with schema validation and constraint checking
-- **Modular, extensible architecture**: cloud providers, task services, clusters, workspaces
-- **Multi-cloud abstraction layer** with unified API (UpCloud, AWS, local infrastructure)
-- **High-performance state management**:
-  - Graph database backend for complex relationships
-  - Real-time state tracking and queries
-  - Multi-model data storage (document, graph, relational)
-- **Enterprise security stack**:
-  - Encrypted configuration and secrets management
-  - Cosmian KMS integration for confidential key management
-  - Cedar policy engine for fine-grained access control
-  - Authorization and permissions control via platform services
-  - Compliance checking and policy enforcement
-  - Anomaly detection for security monitoring
-  - Audit logging and compliance tracking
-- **Hybrid orchestration**: Rust-based performance layer + scripting flexibility
-- **Production-ready features**:
-  - Batch workflows with dependency resolution
-  - Checkpoint recovery and automatic rollback
-  - Parallel execution with state management
-- **Adaptable deployment modes**:
-  - Interactive TUI for guided setup
-  - Headless CLI for scripted automation
-  - Unattended mode for CI/CD pipelines
-- **Hierarchical configuration system** with inheritance and overrides
-
-### What It Does
-
-- **Provisions Infrastructure** - Create servers, networks, storage across multiple cloud providers
-- **Installs Services** - Deploy Kubernetes, containerd, databases, monitoring, and 50+ infrastructure components
-- **Manages Clusters** - Orchestrate complete cluster deployments with dependency management
-- **Handles Configuration** - Hierarchical configuration system with inheritance and overrides
-- **Orchestrates Workflows** - Batch operations with parallel execution and checkpoint recovery
-- **Manages Secrets** - SOPS/Age integration for encrypted configuration
-
----
-
-## Why Provisioning
-
-### The Problems It Solves
-
-#### 1. **Multi-Cloud Complexity**
-
-**Problem**: Each cloud provider has different APIs, tools, and workflows.
-
-**Solution**: Unified abstraction layer with provider-agnostic interfaces. Write configuration once, deploy anywhere.
-
-```toml
-# Same configuration works on UpCloud, AWS, or local infrastructure
-server: Server {
-    name = "web-01"
-    plan = "medium"      # Abstract size, provider-specific translation
-    provider = "upcloud" # Switch to "aws" or "local" as needed
-}
-```
-
-#### 2. **Dependency Hell**
-
-**Problem**: Infrastructure components have complex dependencies (Kubernetes needs containerd, Cilium needs Kubernetes, etc.).
-
-**Solution**: Automatic dependency resolution with topological sorting and health checks.
-
-```bash
-# Provisioning resolves: containerd → etcd → kubernetes → cilium
-taskservs = ["cilium"]  # Automatically installs all dependencies
-```
-
-#### 3. **Configuration Sprawl**
-
-**Problem**: Environment variables, hardcoded values, scattered configuration files.
-
-**Solution**: Hierarchical configuration system with 476+ config accessors replacing 200+ ENV variables.
-
-```toml
-Defaults → User → Project → Infrastructure → Environment → Runtime
-```
-
-#### 4. **Imperative Scripts**
-
-**Problem**: Brittle shell scripts that don't handle failures, don't support rollback, hard to maintain.
-
-**Solution**: Declarative Nickel configurations with validation, type safety, and automatic rollback.
-
-#### 5. **Lack of Visibility**
-
-**Problem**: No insight into what's happening during deployment, hard to debug failures.
-
-**Solution**:
-
-- Real-time workflow monitoring
-- Comprehensive logging system
-- Web-based control center
-- REST API for integration
-
-#### 6. **No Standardization**
-
-**Problem**: Each team builds their own deployment tools, no shared patterns.
-
-**Solution**: Reusable task services, cluster templates, and workflow patterns.
-
----
-
-## Core Concepts
-
-### 1. **Providers**
-
-Cloud infrastructure backends that handle resource provisioning.
-
-- **UpCloud** - Primary cloud provider
-- **AWS** - Amazon Web Services integration
-- **Local** - Local infrastructure (VMs, Docker, bare metal)
-
-Providers implement a common interface, making infrastructure code portable.
-
-### 2. **Task Services (TaskServs)**
-
-Reusable infrastructure components that can be installed on servers.
-
-**Categories**:
-
-- **Container Runtimes** - containerd, Docker, Podman, crun, runc, youki
-- **Orchestration** - Kubernetes, etcd, CoreDNS
-- **Networking** - Cilium, Flannel, Calico, ip-aliases
-- **Storage** - Rook-Ceph, local storage
-- **Databases** - PostgreSQL, Redis, SurrealDB
-- **Observability** - Prometheus, Grafana, Loki
-- **Security** - Webhook, KMS, Vault
-- **Development** - Gitea, Radicle, ORAS
-
-Each task service includes:
-
-- Version management
-- Dependency declarations
-- Health checks
-- Installation/uninstallation logic
-- Configuration schemas
-
-### 3. **Clusters**
-
-Complete infrastructure deployments combining servers and task services.
-
-**Examples**:
-
-- **Kubernetes Cluster** - HA control plane + worker nodes + CNI + storage
-- **Database Cluster** - Replicated PostgreSQL with backup
-- **Build Infrastructure** - BuildKit + container registry + CI/CD
-
-Clusters handle:
-
-- Multi-node coordination
-- Service distribution
-- High availability
-- Rolling updates
-
-### 4. **Workspaces**
-
-Isolated environments for different projects or deployment stages.

-## How It Works
-
-### Data Flow
-
-```bash
-1. User defines infrastructure in Nickel
-   ↓
-2. CLI loads configuration (hierarchical)
-   ↓
-3. Configuration validated against schemas
-   ↓
-4. Workflow created with operations
-   ↓
-5. Orchestrator receives workflow
-   ↓
-6. Dependencies resolved (topological sort)
-   ↓
-7. Operations executed in order
-   ↓
-8. Providers handle cloud operations
-   ↓
-9. Task services installed on servers
-   ↓
-10. State persisted and monitored
-```
-
-### Example Workflow: Deploy Kubernetes Cluster
-
-**Step 1**: Define infrastructure in Nickel
-
-```nickel
-# infra/my-cluster.ncl
-let config = {
-  infra = {
-    name = "my-cluster",
-    provider = "upcloud",
-  },
-
-  servers = [
-    {name = "control-01", plan = "medium", role = "control"},
-    {name = "worker-01", plan = "large", role = "worker"},
-    {name = "worker-02", plan = "large", role = "worker"},
-  ],
-
-  taskservs = ["kubernetes", "cilium", "rook-ceph"],
-} in
-config
-```
-
-**Step 2**: Submit to Provisioning
-
-```bash
-provisioning server create --infra my-cluster
-```
-
-**Step 3**: Provisioning executes workflow
-
-```bash
-1. Create workflow: "deploy-my-cluster"
-2. Resolve dependencies:
-   - containerd (required by kubernetes)
-   - etcd (required by kubernetes)
-   - kubernetes (explicitly requested)
-   - cilium (explicitly requested, requires kubernetes)
-   - rook-ceph (explicitly requested, requires kubernetes)
-
-3. Execution order:
-   a. Provision servers (parallel)
-   b. Install containerd on all nodes
-   c. Install etcd on control nodes
-   d. Install kubernetes control plane
-   e. Join worker nodes
-   f. Install Cilium CNI
-   g. Install Rook-Ceph storage
-
-4. Checkpoint after each step
-5. Monitor health checks
-6. Report completion
-```
-
-**Step 4**: Verify deployment
-
-```bash
-provisioning cluster status my-cluster
-```
-
-### Configuration Hierarchy
-
-Configuration values are resolved through a hierarchy:
-
-```toml
-1. System Defaults (provisioning/config/config.defaults.toml)
-   ↓ (overridden by)
-2. User Preferences (~/.config/provisioning/user_config.yaml)
-   ↓ (overridden by)
-3. Workspace Config (workspace/config/provisioning.yaml)
-   ↓ (overridden by)
-4. Infrastructure Config (workspace/infra/<name>/config.toml)
-   ↓ (overridden by)
-5. Environment Config (workspace/config/prod-defaults.toml)
-   ↓ (overridden by)
-6. Runtime Flags (--flag value)
-```
-
-**Example**:
-
-```bash
-# System default
-[servers]
-default_plan = "small"
-
-# User preference
-[servers]
-default_plan = "medium"  # Overrides system default
-
-# Infrastructure config
-[servers]
-default_plan = "large"   # Overrides user preference
-
-# Runtime
-provisioning server create --plan xlarge  # Overrides everything
-```
-
----
-
-## Use Cases
-
-### 1. **Multi-Cloud Kubernetes Deployment**
-
-Deploy Kubernetes clusters across different cloud providers with identical configuration.
-
-```yaml
-# UpCloud cluster
-provisioning cluster create k8s-prod --provider upcloud
-
-# AWS cluster (same config)
-provisioning cluster create k8s-prod --provider aws
-```
-
-### 2. **Development → Staging → Production Pipeline**
-
-Manage multiple environments with workspace switching.
-
-```bash
-# Development
-provisioning workspace switch dev
-provisioning cluster create app-stack
-
-# Staging (same config, different resources)
-provisioning workspace switch staging
-provisioning cluster create app-stack
-
-# Production (HA, larger resources)
-provisioning workspace switch prod
-provisioning cluster create app-stack
-```
-
-### 3. **Infrastructure as Code Testing**
-
-Test infrastructure changes before deploying to production.
-
-```bash
-# Test Kubernetes upgrade locally
-provisioning test topology load kubernetes_3node | 
-  test env cluster kubernetes --version 1.29.0
-
-# Verify functionality
-provisioning test env run <env-id>
-
-# Cleanup
-provisioning test env cleanup <env-id>
-```
-
-### 4. **Batch Multi-Region Deployment**
-
-Deploy to multiple regions in parallel.
-
-```bash
-# workflows/multi-region.ncl
-let batch_workflow = {
-  operations = [
-    {
-      id = "eu-cluster",
-      type = "cluster",
-      region = "eu-west-1",
-      cluster = "app-stack",
-    },
-    {
-      id = "us-cluster",
-      type = "cluster",
-      region = "us-east-1",
-      cluster = "app-stack",
-    },
-    {
-      id = "asia-cluster",
-      type = "cluster",
-      region = "ap-south-1",
-      cluster = "app-stack",
-    },
-  ],
-  parallel_limit = 3,  # All at once
-} in
-batch_workflow
-```
-
-```bash
-provisioning batch submit workflows/multi-region.ncl
-provisioning batch monitor <workflow-id>
-```
-
-### 5. **Automated Disaster Recovery**
-
-Recreate infrastructure from configuration.
-
-```toml
-# Infrastructure destroyed
-provisioning workspace switch prod
-
-# Recreate from config
-provisioning cluster create --infra backup-restore --wait
-
-# All services restored with same configuration
-```
-
-### 6. **CI/CD Integration**
-
-Automated testing and deployment pipelines.
-
-```bash
-# .gitlab-ci.yml
-test-infrastructure:
-  script:
-  - provisioning test quick kubernetes
-  - provisioning test quick postgres
-
-deploy-staging:
-  script:
-  - provisioning workspace switch staging
-  - provisioning cluster create app-stack --check
-  - provisioning cluster create app-stack --yes
-
-deploy-production:
-  when: manual
-  script:
-  - provisioning workspace switch prod
-  - provisioning cluster create app-stack --yes
-```

+## Core Technologies
 
-## Key Concepts
+- **Rust**: Platform services and performance-critical components
+- **Nushell**: Scripting, CLI, and automation
+- **Nickel**: Type-safe infrastructure configuration
+- **SecretumVault**: Secrets management integration
 
-### Infrastructure as Code (IaC)
+## Workspace-First Approach
 
-The provisioning platform uses **declarative configuration** to manage infrastructure. Instead of manually creating resources, you define what you
-want in Nickel configuration files, and the system makes it happen.
+Provisioning uses workspaces as the default organizational unit. A workspace contains:
 
-### Mode-Based Architecture
+- Infrastructure definitions (Nickel schemas)
+- Environment-specific settings
+- Custom extensions and providers
+- Deployment state and metadata
 
-The system supports four operational modes:
+All operations work within workspace context, providing isolation and consistency.
 
-- **Solo**: Single developer local development
-- **Multi-user**: Team collaboration with shared services
-- **CI/CD**: Automated pipeline execution
-- **Enterprise**: Production deployment with strict compliance
+## Support and Community
 
-### Extension System
-
-Extensibility through:
-
-- **Providers**: Cloud platform integrations (AWS, UpCloud, Local)
-- **Task Services**: Infrastructure components (Kubernetes, databases, etc.)
-- **Clusters**: Complete deployment configurations
-
-### OCI-Native Distribution
-
-Extensions and packages distributed as OCI artifacts, enabling:
-
-- Industry-standard packaging
-- Efficient caching and bandwidth
-- Version pinning and rollback
-- Air-gapped deployments

 ```
 
-## Security and Privacy
+### Configuration File
 
-The AI system implements strict security controls:
+```yaml
+# ~/.config/provisioning/ai.yaml
+ai:
+  enabled: true
+  provider: openai
+  model: gpt-4
+  api_key: ${PROVISIONING_AI_API_KEY}
 
-- ✅ **Cedar Policies**: AI access controlled by Cedar authorization
-- ✅ **Secret Isolation**: AI cannot access secrets directly
-- ✅ **Human Approval**: Critical operations require human approval
-- ✅ **Audit Trail**: All AI operations logged
-- ✅ **Data Sanitization**: Secrets/PII sanitized before sending to LLM
-- ✅ **Local Models**: Support for air-gapped deployments
+  service:
+    port: 9091
+    timeout: 30
+    max_retries: 3
 
-See [Security Policies](security-policies.md) for complete details.
+  typedialog:
+    ai_enabled: true
+    ag_enabled: true
+    suggestions: true
 
-## Supported LLM Providers
+  rag:
+    enabled: true
+    similarity_threshold: 0.75
+    max_results: 5
 
-|  | Provider | Models | Best For |  |
-|  | ---------- | -------- | ---------- |  |
-|  | **Anthropic** | Claude Sonnet 4, Claude Opus 4 | Complex configs, long context |  |
-|  | **OpenAI** | GPT-4 Turbo, GPT-4 | Fast suggestions, tool calling |  |
-|  | **Local** | Llama 3, Mistral | Air-gapped, privacy-critical |  |
+  detector:
+    enabled: true
+    update_interval: 60
+    alert_threshold: 0.8
+```
 
-## Cost Considerations
+## Use Cases
 
-AI features incur LLM API costs. The system implements cost controls:
+### 1. Infrastructure from Description
 
-- **Caching**: Reduces API calls by 50-80%
-- **Rate Limiting**: Prevents runaway costs
-- **Budget Limits**: Daily/monthly cost caps
-- **Local Models**: Zero marginal cost for air-gapped deployments
+Describe infrastructure in natural language, get Nickel configuration:
 
-See [Cost Management](cost-management.md) for optimization strategies.
+```bash
+provisioning ai deploy "
+  Create a production Kubernetes cluster with:
+  - 3 control planes
+  - 5 worker nodes
+  - HA PostgreSQL (3 nodes)
+  - Prometheus monitoring
+  - Encrypted networking
+"
+```
 
-## Architecture Decision Record
+### 2. Configuration Assistance
 
-The AI integration is documented in:
-- [ADR-015: AI Integration Architecture](../architecture/adr/adr-015-ai-integration-architecture.md)
+Get AI suggestions while filling out forms:
 
-## Next Steps
+```bash
+provisioning setup profile
+# TypeDialog shows suggestions based on context
+# Database recommendations based on workload
+# Security settings optimized for environment
+```
 
-1. Read [Architecture](architecture.md) to understand AI system design
-2. Configure AI features in [Configuration](configuration.md)
-3. Try [Natural Language Config](natural-language-config.md) for your first AI-generated config
-4. Explore [AI Agents](ai-agents.md) for automation workflows
-5. Review [Security Policies](security-policies.md) to understand access controls
+### 3. Troubleshooting
 
----
+AI analyzes logs and suggests fixes:
 
-**Version**: 1.0
-**Last Updated**: 2025-01-08
-**Status**: Active
+```bash
+provisioning ai troubleshoot --service orchestrator
+
+# Output:
+# Issue detected: High memory usage
+# Likely cause: Task queue backlog
+# Suggestion: Scale orchestrator replicas to 3
+# Command: provisioning orchestrator scale --replicas 3
+```
+
+### 4. Anomaly Detection
+
+Continuous monitoring with intelligent alerts:
+
+```bash
+provisioning ai anomalies --since 1h
+
+# Output:
+# ⚠️  Unusual pattern detected
+# Time: 2026-01-16T01:47:00Z
+# Service: control-center
+# Metric: API response time
+# Baseline: 45ms → Current: 320ms (+611%)
+# Likelihood: Query performance regression
+```
+
+## Limitations
+
+- **LLM Dependency**: Requires external LLM provider (OpenAI, Anthropic, etc.)
+- **Network Required**: Cloud-based LLM providers need internet connectivity
+- **Context Window**: Large infrastructures may exceed LLM context limits
+- **Cost**: API calls incur per-token charges
+- **Latency**: Natural language processing adds response latency (2-5 seconds)
+
+## Configuration Files
+
+Key files for AI configuration:
+
+| File | Purpose |
+| --- | --- |
+| `.typedialog/ai.db` | AI SurrealDB database (typedialog-ai) |
+| `.typedialog/agent-*.yaml` | AI agent definitions (typedialog-ag) |
+| `~/.config/provisioning/ai.yaml` | User AI settings |
+| `provisioning/core/versions.ncl` | TypeDialog versions |
+| `core/nulib/lib_provisioning/ai/` | Core AI libraries |
+| `platform/crates/ai-service/` | AI service crate |
+
+## Performance
+
+### Typical Latencies
+
+| Operation | Latency |
+| --- | --- |
+| Simple request parsing | 100-200ms |
+| LLM inference | 2-5 seconds |
+| Configuration generation | 500ms-1s |
+| Anomaly detection | 50-100ms |
+
+### Scalability
+
+- **Concurrent requests**: 100+ (load balanced)
+- **Query processing**: 10,000+ queries/second
+- **RAG similarity search**: <50ms for 1M documents
+- **Anomaly detection**: Real-time on 1000+ metrics
+
+## Security
+
+### API Keys
+
+- Stored encrypted in vault-service
+- Never logged or persisted in plain text
+- Rotated automatically (configurable)
+- Audit trail for all API usage
+
+### Data Privacy
+
+- Natural language queries not stored by default
+- LLM provider agreements (OpenAI terms, etc.)
+- Local-only RAG option available
+- GDPR compliance support

-# Autonomous AI Agents (typdialog-ag)
-
-**Status**: 🔴 Planned (Q2 2025 target)
-
-Autonomous AI Agents is a planned feature that enables AI agents to execute multi-step
-infrastructure provisioning workflows with minimal human intervention. Agents make
-decisions, adapt to changing conditions, and execute complex tasks while maintaining
-security and requiring human approval for critical operations.
-
-## Feature Overview
-
-### What It Does
-
-Enable AI agents to manage complex provisioning workflows:
-
-```bash
-User Goal:
-  "Set up a complete development environment with:
-   - PostgreSQL database
-   - Redis cache
-   - Kubernetes cluster
-   - Monitoring stack
-   - Logging infrastructure"
-
-AI Agent executes:
-1. Analyzes requirements and constraints
-2. Plans multi-step deployment sequence
-3. Creates configurations for all components
-4. Validates configurations against policies
-5. Requests human approval for critical decisions
-6. Executes deployment in correct order
-7. Monitors for failures and adapts
-8. Reports completion and recommendations
-```
-
-## Agent Capabilities
-
-### Multi-Step Workflow Execution
-
-Agents coordinate complex, multi-component deployments:
-
-```bash
-Goal: "Deploy production Kubernetes cluster with managed databases"
-
-Agent Plan:
-  Phase 1: Infrastructure
-    ├─ Create VPC and networking
-    ├─ Set up security groups
-    └─ Configure IAM roles
-
-  Phase 2: Kubernetes
-    ├─ Create EKS cluster
-    ├─ Configure network plugins
-    ├─ Set up autoscaling
-    └─ Install cluster add-ons
-
-  Phase 3: Managed Services
-    ├─ Provision RDS PostgreSQL
-    ├─ Configure backups
-    └─ Set up replicas
-
-  Phase 4: Observability
-    ├─ Deploy Prometheus
-    ├─ Deploy Grafana
-    ├─ Configure log collection
-    └─ Set up alerting
-
-  Phase 5: Validation
-    ├─ Run smoke tests
-    ├─ Verify connectivity
-    └─ Check compliance
-```
-
-### Adaptive Decision Making
-
-Agents adapt to conditions and make intelligent decisions:
-
-```bash
-Scenario: Database provisioning fails due to resource quota
-
-Standard approach (human):
-1. Detect failure
-2. Investigate issue
-3. Decide on fix (reduce size, change region, etc.)
-4. Update config
-5. Retry
-
-Agent approach:
-1. Detect failure
-2. Analyze error: "Quota exceeded for db.r6g.xlarge"
-3. Check available options:
-   - Try smaller instance: db.r6g.large (may be insufficient)
-   - Try different region: different cost, latency
-   - Request quota increase (requires human approval)
-4. Ask human: "Quota exceeded. Suggest: use db.r6g.large instead 
-   (slightly reduced performance). Approve? [yes/no/try-other]"
-5. Execute based on approval
-6. Continue workflow
-```
-
-### Dependency Management
-
-Agents understand resource dependencies:
-
-```bash
-Knowledge graph of dependencies:
-
-  VPC ──→ Subnets ──→ EC2 Instances
-   ├─────────→ Security Groups
-   └────→ NAT Gateway ──→ Route Tables
-
-  RDS ──→ DB Subnet Group ──→ VPC
-   ├─────────→ Security Group
-   └────→ Parameter Group
-
-Agent ensures:
-- VPC exists before creating subnets
-- Subnets exist before creating EC2
-- Security groups reference correct VPC
-- Deployment order respects all dependencies
-- Rollback order is reverse of creation
-```
-

-
-[Start deployment?] [Review configs]
-
-User: Review configs
-
-[User reviews and approves]
-
-[Agent executes deployment in phases]
-```
-
-## Safety and Control
-
-### Human-in-the-Loop Checkpoints
-
-Agents stop and ask humans for approval at critical points:
-
-```bash
-Automatic Approval (Agent decides):
-- Create configuration
-- Validate configuration
-- Check dependencies
-- Generate execution plan
-
-Human Approval Required:
-- First-time resource creation
-- Cost changes > 10%
-- Security policy changes
-- Cross-region deployment
-- Data deletion operations
-- Major version upgrades
-```
-
-### Decision Logging
-
-All decisions logged for audit trail:
-
-```bash
-Agent Decision Log:
-| 2025-01-13 10:00:00 | Generate database config |
-| 2025-01-13 10:00:05 | Config validation: PASS |
-| 2025-01-13 10:00:07 | Requesting human approval: "Create new PostgreSQL instance" |
-| 2025-01-13 10:00:45 | Human approval: APPROVED |
-| 2025-01-13 10:00:47 | Cost estimate: $100/month - within budget |
-| 2025-01-13 10:01:00 | Creating infrastructure... |
-| 2025-01-13 10:02:15 | Database created successfully |
-| 2025-01-13 10:02:16 | Running health checks... |
-| 2025-01-13 10:02:45 | Health check: PASSED |
-```
-
-### Rollback Capability
-
-Agents can rollback on failure:
-
-```bash
-Scenario: Database creation succeeds, but Kubernetes creation fails
-
-Agent behavior:
-1. Detect failure in Kubernetes phase
-2. Try recovery (retry, different configuration)
-3. Recovery fails
-4. Ask human: "Kubernetes creation failed. Rollback database creation? [yes/no]"
-5. If yes: Delete database, clean up, report failure
-6. If no: Keep database, manual cleanup needed
-
-Full rollback capability if entire workflow fails before human approval.
-```
-
-## Configuration
-
-### Agent Settings
-
-```toml
-# In provisioning/config/ai.toml
-[ai.agents]
-enabled = true
-
-# Agent decision-making
-auto_approve_threshold = 0.95  # Approve if confidence > 95%
-require_approval_for = [
-  "first_resource_creation",
-  "cost_change_above_percent",
-  "security_policy_change",
-  "data_deletion",
-]
-
-cost_change_threshold_percent = 10
-
-# Execution control
-max_parallel_phases = 2
-phase_timeout_minutes = 30
-execution_log_retention_days = 90
-
-# Safety
-dry_run_mode = false  # Always perform dry run first
-require_final_approval = true
-rollback_on_failure = true
-
-# Learning
-track_agent_decisions = true
-track_success_rate = true
-improve_from_feedback = true
-```

-## Planned Features
-
-### 1. Smart Field Suggestions
-
-Intelligent suggestions based on context:
-
-```bash
-Scenario: User filling database configuration form
-
-1. Engine selection
-   User types: "post" 
-   Suggestion: "postgresql" (99% match)
-   Explanation: "PostgreSQL is the most popular open-source relational database"
-
-2. Storage size
-   User has selected: "postgresql", "production", "web-application"
-   Suggestions appear:
-   • "100 GB" (standard production web app database)
-   • "500 GB" (if expected growth > 1000 connections)
-   • "1 TB" (high-traffic SaaS platform)
-   Explanation: "For typical web applications with 1000s of concurrent users, 100 GB is recommended"
-
-3. Backup frequency
-   User has selected: "production", "critical-data"
-   Suggestions appear:
-   • "Daily" (standard for critical databases)
-   • "Hourly" (for data warehouses with frequent updates)
-   Explanation: "Critical production data requires daily or more frequent backups"
-```
-
-### 2. Validation Error Explanation
-
-Human-readable error messages with fixes:
-
-```bash
-User enters: "storage = -100"
-
-Current behavior:
-  ✗ Error: Expected positive integer
-
-Planned AI behavior:
-  ✗ Storage must be positive (1-65535 GB)
-  
-  Why: Negative storage doesn't make sense.
-       Storage capacity must be at least 1 GB.
-  
-  Fix suggestions:
-  • Use 100 GB (typical production size)
-  • Use 50 GB (development environment)
-  • Use your required size in GB
-```
-
-### 3. Field-to-Field Context Awareness
-
-Suggestions change based on other fields:
-
-```bash
-Scenario: Multi-step configuration form
-
-Step 1: Select environment
-User: "production"
-  → Form shows constraints: (min storage 50GB, encryption required, backup required)
-
-Step 2: Select database engine
-User: "postgresql"
-  → Suggestions adapted:
-    - PostgreSQL 15 recommended for production
-    - Point-in-time recovery available
-    - Replication options highlighted
-
-Step 3: Storage size
-  → Suggestions show:
-    - Minimum 50 GB for production
-    - Examples from similar production configs
-    - Cost estimate updates in real-time
-
-Step 4: Encryption
-  → Suggestion appears: "Recommended: AES-256"
-  → Explanation: "Required for production environments"
-```
-
-### 4. Inline Documentation
-
-Quick access to relevant docs:
-
-```bash
-Field: "Backup Retention Days"
-
-Suggestion popup:
-  ┌─────────────────────────────────┐
-  │ Suggested value: 30              │
-  │                                 │
-  │ Why: 30 days is industry-standard│
-  │ standard for compliance (PCI-DSS)│
-  │                                 │
-  │ Learn more:                      │
-  │ → Backup best practices guide    │
-  │ → Your compliance requirements   │
-  │ → Cost vs retention trade-offs   │
-  └─────────────────────────────────┘
-```
-
-### 5. Multi-Field Suggestions
-
-Suggest multiple related fields together:
-
-```bash
-User selects: environment = "production"
-
-AI suggests completing:
-  ┌─────────────────────────────────┐
-  │ Complete Production Setup        │
-  │                                 │
-  │ Based on production environment │
-  │ we recommend:                    │
-  │                                 │
-  │ Encryption: enabled              │ ← Auto-fill
-  │ Backups: daily                   │ ← Auto-fill
-  │ Monitoring: enabled              │ ← Auto-fill
-  │ High availability: enabled       │ ← Auto-fill
-  │ Retention: 30 days              │ ← Auto-fill
-  │                                 │
-  │ [Accept All] [Review] [Skip]    │
-  └─────────────────────────────────┘

-## User Experience Flow
-
-### Scenario: New User Configuring PostgreSQL
-
-```toml
-1. User opens typdialog form
-   - Form title: "Create Database"
-   - First field: "Database Engine"
-   - AI shows: "PostgreSQL recommended for relational data"
-
-2. User types "post"
-   - Autocomplete shows: "postgresql"
-   - AI explains: "PostgreSQL is the most stable open-source database"
-
-3. User selects "postgresql"
-   - Form progresses
-   - Next field: "Version"
-   - AI suggests: "PostgreSQL 15 (latest stable)"
-   - Explanation: "Version 15 is current stable, recommended for new deployments"
-
-4. User selects version 15
-   - Next field: "Environment"
-   - User selects "production"
-   - AI note appears: "Production environment requires encryption and backups"
-
-5. Next field: "Storage (GB)"
-   - Form shows: Minimum 50 GB (production requirement)
-   - AI suggestions:
-     • 100 GB (standard production)
-     • 250 GB (high-traffic site)
-   - User accepts: 100 GB
-
-6. Validation error on next field
-   - Old behavior: "Invalid backup_days value"
-   - New behavior: 
-     "Backup retention must be 1-35 days. Recommended: 30 days.
-     30-day retention meets compliance requirements for production systems."
-
-7. User completes form
-   - Summary shows all AI-assisted decisions
-   - Generate button creates configuration
-```
-

-# AI Cost Management and Optimization
-
-**Status**: ✅ Production-Ready (cost tracking, budgets, caching benefits)
-
-Comprehensive guide to managing LLM API costs, optimizing usage through caching and rate limiting, and tracking spending. The provisioning platform
-includes built-in cost controls to prevent runaway spending while maximizing value.
-
-## Cost Overview
-
-### API Provider Pricing
-
-| Provider | Model | Input | Output | Per MTok |  |
-| ---------- | ------- | ------- | -------- | ---------- |  |
-| **Anthropic** | Claude Sonnet 4 | $3 | $15 | $0.003 input / $0.015 output |  |
-|  | Claude Opus 4 | $15 | $45 | Higher accuracy, longer context |  |
-|  | Claude Haiku 4 | $0.80 | $4 | Fast, for simple queries |  |
-| **OpenAI** | GPT-4 Turbo | $0.01 | $0.03 | Per 1K tokens |  |
-|  | GPT-4 | $0.03 | $0.06 | Legacy, avoid |  |
-|  | GPT-4o | $5 | $15 | Per MTok |  |
-| **Local** | Llama 2, Mistral | Free | Free | Hardware cost only |  |
-
-### Cost Examples
-
-```bash
-Scenario 1: Generate simple database configuration
-  - Input: 500 tokens (description + schema)
-  - Output: 200 tokens (generated config)
-  - Cost: (500 × $3 + 200 × $15) / 1,000,000 = $0.0045
-  - With caching (hit rate 50%): $0.0023
-
-Scenario 2: Deep troubleshooting analysis
-  - Input: 5000 tokens (logs + context)
-  - Output: 2000 tokens (analysis + recommendations)
-  - Cost: (5000 × $3 + 2000 × $15) / 1,000,000 = $0.045
-  - With caching (hit rate 70%): $0.0135
-
-Scenario 3: Monthly usage (typical organization)
-  - ~1000 config generations @ $0.005 = $5
-  - ~500 troubleshooting calls @ $0.045 = $22.50
-  - ~2000 form assists @ $0.002 = $4
-  - ~200 agent executions @ $0.10 = $20
-  - **Total: ~$50-100/month for small org**
-  - **Total: ~$500-1000/month for large org**
-```
-
-## Cost Control Mechanisms
-
-### Request Caching
-
-Caching is the primary cost reduction strategy, cutting costs by 50-80%:
-
-```bash
-Without Caching:
-  User 1: "Generate PostgreSQL config" → API call → $0.005
-  User 2: "Generate PostgreSQL config" → API call → $0.005
-  Total: $0.010 (2 identical requests)
-
-With LRU Cache:
-  User 1: "Generate PostgreSQL config" → API call → $0.005
-  User 2: "Generate PostgreSQL config" → Cache hit → $0.00001
-  Total: $0.00501 (500x cost reduction for identical)
-
-With Semantic Cache:
-  User 1: "Generate PostgreSQL database config" → API call → $0.005
-  User 2: "Create a PostgreSQL database" → Semantic hit → $0.00001
-  (Slightly different wording, but same intent)
-  Total: $0.00501 (near 500x reduction for similar)
-```
-
-### Cache Configuration
-
-```toml
-[ai.cache]
-enabled = true
-cache_type = "redis"  # Distributed cache across instances
-ttl_seconds = 3600    # 1-hour cache lifetime
-
-# Cache size limits
-max_size_mb = 500
-eviction_policy = "lru"  # Least Recently Used
-
-# Semantic caching - cache similar queries
-[ai.cache.semantic]
-enabled = true
-similarity_threshold = 0.95  # Cache if 95%+ similar to previous query
-cache_embeddings = true      # Cache embedding vectors themselves
-
-# Cache metrics
-[ai.cache.metrics]
-track_hit_rate = true
-track_space_usage = true
-alert_on_low_hit_rate = true
-```
-
-### Rate Limiting
-
-Prevent usage spikes from unexpected costs:
-
-```toml
-[ai.limits]
-# Per-request limits
-max_tokens = 4096
-max_input_tokens = 8192
-max_output_tokens = 4096
-
-# Throughput limits
-rpm_limit = 60                    # 60 requests per minute
-rpm_burst = 100                   # Allow burst to 100
-daily_request_limit = 5000        # Max 5000 requests/day
-
-# Cost limits
-daily_cost_limit_usd = 100        # Stop at $100/day
-monthly_cost_limit_usd = 2000     # Stop at $2000/month
-
-# Budget alerts
-warn_at_percent = 80              # Warn when at 80% of daily budget
-stop_at_percent = 95              # Stop when at 95% of budget
-```
-
-### Workspace-Level Budgets
-
-```toml
-[ai.workspace_budgets]
-# Per-workspace cost limits
-dev.daily_limit_usd = 10
-staging.daily_limit_usd = 50
-prod.daily_limit_usd = 100
-
-# Can override globally for specific workspaces
-teams.team-a.monthly_limit = 500
-teams.team-b.monthly_limit = 300
-```
-
-## Cost Tracking
-
-### Track Spending
-
-```bash
-# View current month spending
-provisioning admin costs show ai
-
-# Forecast monthly spend
-provisioning admin costs forecast ai --days-remaining 15
-
-# Analyze by feature
-provisioning admin costs analyze ai --by feature
-
-# Analyze by user
-provisioning admin costs analyze ai --by user
-
-# Export for billing
-provisioning admin costs export ai --format csv --output costs.csv
-```
-
-### Cost Breakdown
-
-```bash
-Month: January 2025
-
-Total Spending: $285.42
-
-By Feature:
-  Config Generation:    $150.00 (52%) [300 requests × avg $0.50]
-  Troubleshooting:      $95.00  (33%) [80 requests × avg $1.19]
-  Form Assistance:      $30.00  (11%) [5000 requests × avg $0.006]
-  Agents:               $10.42  (4%)  [20 runs × avg $0.52]
-
-By Provider:

-  Cache hits: 35,000 (70%)
-  Cache misses: 15,000 (30%)
-  Cost savings from cache: ~$175 (38% reduction)
-```
-
-## Optimization Strategies
-
-### Strategy 1: Increase Cache Hit Rate
-
-```bash
-# Longer TTL = more cache hits
-[ai.cache]
-ttl_seconds = 7200  # 2 hours instead of 1 hour
-
-# Semantic caching helps with slight variations
-[ai.cache.semantic]
-enabled = true
-similarity_threshold = 0.90  # Lower threshold = more hits
-
-# Result: Increase hit rate from 65% → 80%
-# Cost reduction: 15% → 23%
-```
-
-### Strategy 2: Use Local Models
-
-```toml
-[ai]
-provider = "local"
-model = "mistral-7b"  # Free, runs on GPU
-
-# Cost: Hardware ($5-20/month) instead of API calls
-# Savings: 50-100 config generations/month × $0.005 = $0.25-0.50
-# Hardware amortized cost: <$0.50/month on existing GPU
-
-# Tradeoff: Slightly lower quality, 2x slower
-```
-
-### Strategy 3: Use Haiku for Simple Tasks
-
-```bash
-Task Complexity vs Model:
-
-Simple (form assist): Claude Haiku 4 ($0.80/$4)
-Medium (config gen): Claude Sonnet 4 ($3/$15)
-Complex (agents): Claude Opus 4 ($15/$45)
-
-Example optimization:
-  Before: All tasks use Sonnet 4
-  - 5000 form assists/month: 5000 × $0.006 = $30
-  
-  After: Route by complexity
-  - 5000 form assists → Haiku: 5000 × $0.001 = $5 (83% savings)
-  - 200 config gen → Sonnet: 200 × $0.005 = $1
-  - 10 agent runs → Opus: 10 × $0.10 = $1
-```
-
-### Strategy 4: Batch Operations
-
-```bash
-# Instead of individual requests, batch similar operations:
-
-# Before: 100 configs, 100 separate API calls
-provisioning ai generate "PostgreSQL config" --output db1.ncl
-provisioning ai generate "PostgreSQL config" --output db2.ncl
-# ... 100 calls = $0.50
-
-# After: Batch similar requests
-provisioning ai batch --input configs-list.yaml
-# Groups similar requests, reuses cache
-# ... 3-5 API calls = $0.02 (90% savings)
-```
-
-### Strategy 5: Smart Feature Enablement
-
-```toml
-[ai.features]
-# Enable high-ROI features
-config_generation = true    # High value, moderate cost
-troubleshooting = true      # High value, higher cost
-rag_search = true           # Low cost, high value
-
-# Disable low-ROI features if cost-constrained
-form_assistance = false     # Low value, non-zero cost (if budget tight)
-agents = false              # Complex, requires multiple calls
-```
-
-## Budget Management Workflow
-
-### 1. Set Budget
-
-```bash
-# Set monthly budget
-provisioning config set ai.budget.monthly_limit_usd 500
-
-# Set daily limit
-provisioning config set ai.limits.daily_cost_limit_usd 50
-
-# Set workspace limits
-provisioning config set ai.workspace_budgets.prod.monthly_limit 300
-provisioning config set ai.workspace_budgets.dev.monthly_limit 100
-```
-
-### 2. Monitor Spending
-
-```bash
-# Daily check
-provisioning admin costs show ai
-
-# Weekly analysis
-provisioning admin costs analyze ai --period week
-
-# Monthly review
-provisioning admin costs analyze ai --period month
-```
-
-### 3. Adjust If Needed
-
-```bash
-# If overspending:
-# - Increase cache TTL
-# - Enable local models for simple tasks
-# - Reduce form assistance (high volume, low cost but adds up)
-# - Route complex tasks to Haiku instead of Opus
-
-# If underspending:
-# - Enable new features (agents, form assistance)
-# - Increase rate limits
-# - Lower cache hit requirements (broader semantic matching)
-```
-
-### 4. Forecast and Plan
-
-```bash
-# Current monthly run rate
-provisioning admin costs forecast ai
-
-# If trending over budget, recommend actions:
-# - Reduce daily limit
-# - Switch to local model for 50% of tasks
-# - Increase batch processing
-
-# If trending under budget:
-# - Enable agents for automation workflows
-# - Enable form assistance across all workspaces
-```
-
-## Cost Allocation
-
-### Chargeback Models
-
-**Per-Workspace Model**:
-```bash
-Development workspace: $50/month
-Staging workspace:     $100/month
-Production workspace:  $300/month
-------
-Total:                 $450/month
-```
-
-**Per-User Model**:
-```bash
-Each user charged based on their usage
-Encourages efficiency
-Difficult to track/allocate
-```
-
-**Shared Pool Model**:
-```bash
-All teams share $1000/month budget
-Budget splits by consumption rate
-Encourages optimization
-Most flexible
-```
-

-## Advanced Cost Optimization
-
-### Hybrid Strategy (Recommended)
-
-```bash
-✓ Local models for:
-  - Form assistance (high volume, low complexity)
-  - Simple validation checks
-  - Document retrieval (RAG)
-  Cost: Hardware only (~$500 setup)
-
-✓ Cloud API for:
-  - Complex generation (requires latest model capability)
-  - Troubleshooting (needs high accuracy)
-  - Agents (complex reasoning)
-  Cost: $50-200/month per organization
-
-Result:
-  - 70% of requests → Local (free after hardware amortization)
-  - 30% of requests → Cloud ($50/month)
-  - 80% overall cost reduction vs cloud-only
-```
-
-## Monitoring and Alerts
-
-### Cost Anomaly Detection
-
-```bash
-# Enable anomaly detection
-provisioning config set ai.monitoring.anomaly_detection true
-
-# Set thresholds
-provisioning config set ai.monitoring.cost_spike_percent 150
-# Alert if daily cost is 150% of average
-
-# System alerts:
-# - Daily cost exceeded by 10x normal
-# - New expensive operation (agent run)
-# - Cache hit rate dropped below 40%
-# - Rate limit nearly exhausted
-```
-
-### Alert Configuration
-
-```toml
-[ai.monitoring.alerts]
-enabled = true
-spike_threshold_percent = 150
-check_interval_minutes = 5
-
-[ai.monitoring.alerts.channels]
-email = "ops@company.com"
-slack = "[https://hooks.slack.com/..."](https://hooks.slack.com/...")
-pagerduty = "integration-key"

-# Alert thresholds
-[ai.monitoring.alerts.thresholds]
-daily_budget_warning_percent = 80
-daily_budget_critical_percent = 95
-monthly_budget_warning_percent = 70

-# Model Context Protocol (MCP) Integration
-
-**Status**: ✅ Production-Ready (MCP 0.6.0+, integrated with Claude, compatible with all LLMs)
-
-The MCP server provides standardized Model Context Protocol integration, allowing external LLMs (Claude, GPT-4, local models) to access provisioning
-platform capabilities as tools. This enables complex multi-step workflows, tool composition, and integration with existing LLM applications.
-
-## Architecture Overview
-
-The MCP integration follows the Model Context Protocol specification:
-
-```bash

-|  | validate_config | 500-1000ms | Parallel schema validation |  |
-|  | search_docs | 300-800ms | RAG hybrid search |  |
-|  | troubleshoot | 3-8s | Depends on log size and analysis depth |  |
-|  | get_schema | 100-300ms | Cached schema retrieval |  |
-|  | check_compliance | 500-2000ms | Policy evaluation |  |
-
-## Configuration
-
-See [Configuration Guide](configuration.md) for MCP-specific settings:
-
-- MCP server port and binding
-- Tool registry customization
-- Rate limiting for tool calls
-- Access control (Cedar policies)
-
-## Security
-
-### Authentication
-
-- Tools require valid provisioning API token
-- Token scoped to user's workspace
-- All tool calls authenticated and logged
-
-### Authorization
-
-- Cedar policies control which tools user can call
-- Example: `allow(principal, action, resource)` when `role == "admin"`
-- Detailed audit trail of all tool invocations
-
-### Data Protection
-
-- Secrets never passed through MCP
-- Configuration sanitized before analysis
-- PII removed from logs sent to external LLMs
-
-## Monitoring and Debugging
-
-```bash
-# Monitor MCP server
-provisioning admin mcp status
-
-# View MCP tool calls
-provisioning admin logs --filter "mcp_tools" --tail 100
-
-# Debug tool response
-RUST_LOG=provisioning::mcp=debug provisioning-mcp-server
-```

-# Natural Language Configuration Generation
-
-**Status**: 🔴 Planned (Q2 2025 target)
-
-Natural Language Configuration (NLC) is a planned feature that enables users to describe infrastructure requirements in plain English and have the
-system automatically generate validated Nickel configurations. This feature combines natural language understanding with schema-aware generation and
-validation.
-
-## Feature Overview
-
-### What It Does
-
-Transform infrastructure descriptions into production-ready Nickel configurations:
-
-```nickel
-User Input:
-  "Create a production PostgreSQL cluster with 100GB storage,
-   daily backups, encryption enabled, and cross-region replication
-   to us-west-2"
-
-System Output:
-  provisioning/schemas/database.ncl (validated, production-ready)
-```
-
-### Primary Use Cases
-
-1. **Rapid Prototyping**: From description to working config in seconds
-2. **Infrastructure Documentation**: Describe infrastructure as code
-3. **Configuration Templates**: Generate reusable patterns
-4. **Non-Expert Operations**: Enable junior developers to provision infrastructure
-5. **Configuration Migration**: Describe existing infrastructure to generate Nickel
-

-## Planned Implementation Details
-
-### 1. Intent Extraction
-
-Extract structured intent from natural language:
-
-```bash
-Input: "Create a production PostgreSQL cluster with encryption and backups"
-
-Extracted Intent:
-{
-  resource_type: "database",
-  engine: "postgresql",
-  environment: "production",
-  requirements: [
-    {constraint: "encryption", type: "boolean", value: true},
-    {constraint: "backups", type: "enabled", frequency: "daily"},
-  ],
-  modifiers: ["production"],
-}
-```
-
-### 2. Entity Mapping
-
-Map natural language entities to schema fields:
-
-```bash
-Description Terms → Schema Fields:
-  "100GB storage" → database.instance.allocated_storage_gb = 100
-  "daily backups" → backup.enabled = true, backup.frequency = "daily"
-  "encryption" → security.encryption_enabled = true
-  "cross-region" → backup.copy_to_region = "us-west-2"
-  "PostgreSQL 15" → database.engine_version = "15.0"
-```
-
-### 3. Prompt Engineering
-
-Sophisticated prompting for schema-aware generation:
-
-```bash
-System Prompt:
-You are generating Nickel infrastructure configurations.
-Generate ONLY valid Nickel syntax.
-Follow these rules:
-- Use record syntax: `field = value`
-- Type annotations must be valid
-- All required fields must be present
-- Apply best practices for [ENVIRONMENT]
-
-Schema Context:
-[Database schema from provisioning/schemas/database.ncl]
-
-Examples:
-[3 relevant examples from RAG]
-
-User Request:
-[User natural language description]
-
-Generate the complete Nickel configuration.
-Start with: let { database = {
-```
-
-### 4. Iterative Refinement
-
-Handle generation errors through iteration:
-
-```bash
-Attempt 1: Generate initial config
-  ↓ Validate
-  ✗ Error: field `version` type mismatch (string vs number)
-  ↓ Re-prompt with error
-Attempt 2: Fix with context from error
-  ↓ Validate
-  ✓ Success: Config is valid
-```
-
-## Command Interface
-
-### CLI Usage
-
-```bash
-# Simple generation
-provisioning ai generate "PostgreSQL database for production"
-
-# With schema specification
-provisioning ai generate 
-  --schema database 
-  "Create PostgreSQL 15 with encryption and daily backups"
-
-# Interactive generation (refine output)
-provisioning ai generate --interactive 
-  "Kubernetes cluster on AWS"
-
-# Generate and validate
-provisioning ai generate 
-  --validate 
-  "Production Redis cluster with sentinel"
-
-# Generate and save directly
-provisioning ai generate 
-  --schema database 
-  --output workspaces/prod/database.ncl 
-  "PostgreSQL production setup"
-
-# Batch generation from file
-provisioning ai generate --batch descriptions.yaml
-```
-
-### Interactive Refinement
-
-```bash
-$ provisioning ai generate --interactive
-> Describe infrastructure: Create production PostgreSQL cluster
-
-Generated configuration shown.
-
-> Refine: Add cross-region backup to us-west-2
-Configuration updated.
-
-> Refine: Use larger instance class for performance
-Configuration updated.
-
-> Accept? [y/n]: y
-Configuration saved to: workspaces/prod/database.ncl
-```
-
-## Example Generations
-
-### Example 1: Simple Database
-
-**Input**:
-```bash
-"PostgreSQL database with 50GB storage and encryption"
-```
-
-**Output**:
-```javascript
-let {
-  database = {
-    engine = "postgresql",
-    version = "15.0",
-    
-    instance = {
-      instance_class = "db.t3.medium",
-      allocated_storage_gb = 50,
-      iops = 1000,
-    },
-    
-    security = {
-      encryption_enabled = true,
-      tls_enabled = true,
-      tls_version = "1.3",
-    },
-    
-    backup = {
-      enabled = true,
-      retention_days = 7,
-    },
-  }
-}
-```
-
-**Rationale**:
-- PostgreSQL 15 is current stable version
-- db.t3.medium suitable for 50GB with general workload
-- Encryption enabled per requirement
-- Automatic backups with 7-day retention (default)
-
-### Example 2: Complex Kubernetes Setup
-
-**Input**:
-```yaml
-"Production Kubernetes cluster in AWS with 3 availability zones,
-auto-scaling from 3 to 10 nodes, managed PostgreSQL, and monitoring"
-```
-
-**Output**:
-```javascript
-let {
-  kubernetes = {
-    version = "1.28.0",
-    
-    cluster = {
-      name = "prod-cluster",
-      region = "us-east-1",
-      availability_zones = ["us-east-1a", "us-east-1b", "us-east-1c"],
-    },
-    
-    node_group = {
-      min_size = 3,
-      max_size = 10,
-      desired_size = 3,
-      instance_type = "t3.large",
-      
-      auto_scaling = {
-        enabled = true,
-        target_cpu = 70,
-        scale_down_delay = 300,
-      },
-    },
-    
-    managed_services = {
-      postgres = {
-        enabled = true,
-        engine = "postgresql",
-        version = "15.0",
-        storage_gb = 100,
-      },
-    },
-    
-    monitoring = {
-      prometheus = {enabled = true},
-      grafana = {enabled = true},
-      cloudwatch_integration = true,
-    },
-    
-    networking = {
-      vpc_cidr = "10.0.0.0/16",
-      enable_nat_gateway = true,
-      enable_dns_hostnames = true,
-    },
-  }
-}
-```
-
-**Rationale**:
-- 3 AZs for high availability
-- t3.large balances cost and performance for general workload
-- Auto-scaling target 70% CPU (best practice)
-- Managed PostgreSQL reduces operational overhead
-- Full observability with Prometheus + Grafana
-
-## Configuration and Constraints
-
-### Configurable Generation Parameters
-
-```toml
-# In provisioning/config/ai.toml
-[ai.generation]
-# Which schema to use by default
-default_schema = "database"
-
-# Whether to require explicit environment specification
-require_environment = false
-
-# Optimization targets
-optimization_target = "balanced"  # or "cost", "performance"
-
-# Best practices to always apply
-best_practices = [
-  "encryption",
-  "high_availability",
-  "monitoring",
-  "backup",
-]
-
-# Constraints that limit generation
-[ai.generation.constraints]
-min_storage_gb = 10
-max_instances = 100
-allowed_engines = ["postgresql", "mysql", "mongodb"]
-
-# Validation before accepting generated config
-[ai.generation.validation]
-strict_mode = true
-require_security_review = false
-require_compliance_check = true
-```
-
-### Safety Guardrails
-
-1. **Required Fields**: All schema required fields must be present
-2. **Type Validation**: Generated values must match schema types
-3. **Security Checks**: Encryption/backups enabled for production
-4. **Cost Estimation**: Warn if projected cost exceeds threshold
-5. **Resource Limits**: Enforce organizational constraints
-6. **Policy Compliance**: Check against Cedar policies
-
-## User Workflow
-
-### Typical Usage Session
-
-```bash
-# 1. Describe infrastructure need
-$ provisioning ai generate "I need a database for my web app"
-
-# System generates basic config, suggests refinements
-# Generated config shown with explanations
-
-# 2. Refine if needed
-$ provisioning ai generate --interactive
-
-# 3. Review and validate
-$ provisioning ai validate workspaces/dev/database.ncl
-
-# 4. Deploy
-$ provisioning workspace apply workspaces/dev
-
-# 5. Monitor
-$ provisioning workspace logs database
-```
-
-## Integration with Other Systems
-
-### RAG Integration
-
-NLC uses RAG to find similar configurations:
-
-```toml
-User: "Create Kubernetes cluster"
-  ↓
-RAG searches for:
-  - Existing Kubernetes configs in workspaces
-  - Kubernetes documentation and examples
-  - Best practices from provisioning/docs/guides/kubernetes.md
-  ↓
-Context fed to LLM for generation
-```
-
-### Form Assistance
-
-NLC and form assistance share components:
-
-- Intent extraction for pre-filling forms
-- Constraint validation for form field values
-- Explanation generation for validation errors
-
-### CLI Integration
-
-```bash
-# Generate then preview
-| provisioning ai generate "PostgreSQL prod" | \ |
-  provisioning config preview
-
-# Generate and apply
-provisioning ai generate 
-  --apply 
-  --environment prod 
-  "PostgreSQL cluster"
-```
-
-## Testing and Validation
-
-### Test Cases (Planned)
-
-1. **Simple Descriptions**: Single resource, few requirements
-   - "PostgreSQL database"
-   - "Redis cache"
-
-2. **Complex Descriptions**: Multiple resources, constraints
-   - "Kubernetes with managed database and monitoring"
-   - "Multi-region deployment with failover"
-
-3. **Edge Cases**:
-   - Conflicting requirements
-   - Ambiguous specifications
-   - Deprecated technologies
-
-4. **Refinement Cycles**:
-   - Interactive generation with multiple refines
-   - Error recovery and re-prompting
-   - User feedback incorporation
-
-## Success Criteria (Q2 2025)
-
-- ✅ Generates valid Nickel for 90% of user descriptions
-- ✅ Generated configs pass all schema validation
-- ✅ Supports top 10 infrastructure patterns
-- ✅ Interactive refinement works smoothly
-- ✅ Error messages explain issues clearly
-- ✅ User testing with non-experts succeeds
-- ✅ Documentation complete with examples
-- ✅ Integration with form assistance operational

+# Natural Language Infrastructure
+
+Use natural language to describe infrastructure requirements and get automatically generated Nickel configurations and deployment plans.
+
+## Overview
+
+Natural Language Infrastructure (NLI) allows requesting infrastructure changes in plain English:
+
+```bash
+# Instead of writing complex Nickel...
+provisioning ai "Deploy a 3-node HA PostgreSQL cluster with automatic backups in AWS"
+
+# Or interactively...
+provisioning ai interactive
+
+# Interactive mode guides you through requirements
+```
+
+## How It Works
+
+### Request Processing Pipeline
+
+```text
+User Natural Language Input
+    ↓
+Intent Recognition
+    ├─ Extract resource type (server, database, cluster)
+    ├─ Identify constraints (HA, region, size)
+    └─ Detect options (monitoring, backup, encryption)
+    ↓
+RAG Knowledge Retrieval
+    ├─ Find similar deployments
+    ├─ Retrieve best practices
+    └─ Get provider-specific guidance
+    ↓
+LLM Inference (GPT-4, Claude 3)

+
+## RAG Retrieval Process
+
+### Similarity Search
+
+When processing a user query, the system:
+
+1. **Embed Query**: Convert natural language to vector
+2. **Search Index**: Find similar documents (cosine similarity > threshold)
+3. **Rank Results**: Score by relevance
+4. **Extract Context**: Select top N chunks
+5. **Augment Prompt**: Add context to LLM request
+
+**Example**:
+
+```bash
+User Query: "Create a Kubernetes cluster in AWS with auto-scaling"
+
+Vector Embedding: [0.234, 0.567, 0.891]
+
+Top Matches:
+1. "HA Kubernetes Setup" (similarity: 0.94)
+2. "AWS Auto-Scaling Patterns" (similarity: 0.87)
+3. "Kubernetes Security Hardening" (similarity: 0.76)
+
+Retrieved Context:
+- Minimum 3 control planes for HA
+- Use AWS ASGs with cluster autoscaler
+- Enable Pod Disruption Budgets
+- Configure network policies
+
+LLM Prompt with Context:
+"Create a Kubernetes cluster with the following context:
+[...retrieved knowledge...]
+User request: Create a Kubernetes cluster in AWS with auto-scaling"
+```

+## Hybrid Search
+
+RAG uses hybrid search combining semantic and keyword matching:
+
+```text
+BM25 Score (Keyword Match): 0.7
+Semantic Score (Vector Similarity): 0.92
+
+Hybrid Score = (0.3 × 0.7) + (0.7 × 0.92)
+             = 0.21 + 0.644
+             = 0.854
+
+Relevance: High ✓
+```
+
+### Configuration
+
+```toml
+[hybrid_search]
+bm25_weight = 0.3
+semantic_weight = 0.7
+```
+
+## Performance
+
+### Retrieval Latency
+
+| Operation | Latency |
+| --- | --- |
+| Embed query (512 tokens) | 100-200ms |
+| Vector similarity search | 20-50ms |
+| BM25 keyword search | 10-30ms |
+| Hybrid ranking | 5-10ms |
+| Total retrieval | 50-100ms |
+
+### Vector Index Size
+
+- **Documents**: 1000 → 8GB storage
+- **Documents**: 10000 → 80GB storage
+- **Search latency**: Consistent <50ms regardless of size (with HNSW indexing)
+
+## Security & Privacy
+
+### Access Control
+
+```bash
+# Restrict knowledge access
+provisioning ai knowledge acl set doc-k8s-ha-001 \

-# Retrieval-Augmented Generation (RAG) System
-
-**Status**: ✅ Production-Ready (SurrealDB 1.5.0+, 22/22 tests passing)
-
-The RAG system enables the AI service to access, retrieve, and reason over infrastructure documentation, schemas, and past configurations. This allows
-the AI to generate contextually accurate infrastructure configurations and provide intelligent troubleshooting advice grounded in actual platform
-knowledge.
-
-## Architecture Overview
-
-The RAG system consists of:
-
-1. **Document Store**: SurrealDB vector store with semantic indexing
-2. **Hybrid Search**: Vector similarity + BM25 keyword search
-3. **Chunk Management**: Intelligent document chunking for code and markdown
-4. **Context Ranking**: Relevance scoring for retrieved documents
-5. **Semantic Cache**: Deduplication of repeated queries
-
-## Core Components
-
-### 1. Vector Embeddings
-
-The system uses embedding models to convert documents into vector representations:
-
-```bash
-┌─────────────────────┐
-│ Document Source     │
-│ (Markdown, Code)    │
-└──────────┬──────────┘
-           │
-           ▼
-┌──────────────────────────────────┐
-│ Chunking & Tokenization          │
-│ - Code-aware splits              │
-│ - Markdown aware                 │
-│ - Preserves context              │
-└──────────┬───────────────────────┘
-           │
-           ▼
-┌──────────────────────────────────┐
-│ Embedding Model                  │
-│ (OpenAI Ada, Anthropic, Local)   │
-└──────────┬───────────────────────┘
-           │
-           ▼
-┌──────────────────────────────────┐
-│ Vector Storage (SurrealDB)       │
-│ - Vector index                   │
-│ - Metadata indexed               │
-│ - BM25 index for keywords        │
-└──────────────────────────────────┘
-```
-
-### 2. SurrealDB Integration
-
-SurrealDB serves as the vector database and knowledge store:
-
-```bash
-# Configuration in provisioning/schemas/ai.ncl
-let {
-  rag = {
-    enabled = true,
-    db_url = "surreal://localhost:8000",
-    namespace = "provisioning",
-    database = "ai_rag",
-    
-    # Collections for different document types
-    collections = {
-      documentation = {
-        chunking_strategy = "markdown",
-        chunk_size = 1024,
-        overlap = 256,
-      },
-      schemas = {
-        chunking_strategy = "code",
-        chunk_size = 512,
-        overlap = 128,
-      },
-      deployments = {
-        chunking_strategy = "json",
-        chunk_size = 2048,
-        overlap = 512,
-      },
-    },
-    
-    # Embedding configuration
-    embedding = {
-      provider = "openai",  # or "anthropic", "local"
-      model = "text-embedding-3-small",
-      cache_vectors = true,
-    },
-    
-    # Search configuration
-    search = {
-      hybrid_enabled = true,
-      vector_weight = 0.7,
-      keyword_weight = 0.3,
-      top_k = 5,  # Number of results to return
-      semantic_cache = true,
-    },
-  }
-}
-```
-
-### 3. Document Chunking
-
-Intelligent chunking preserves context while managing token limits:
-
-#### Markdown Chunking Strategy
-
-```bash
-Input Document: provisioning/docs/src/guides/from-scratch.md
-
-Chunks:
-  [1] Header + first section (up to 1024 tokens)
-  [2] Next logical section + overlap with [1]
-  [3] Code examples preserve as atomic units
-  [4] Continue with overlap...
-
-Each chunk includes:
-  - Original section heading (for context)
-  - Content
-  - Source file and line numbers
-  - Metadata (doctype, category, version)
-```
-
-#### Code Chunking Strategy
-
-```bash
-Input Document: provisioning/schemas/main.ncl
-
-Chunks:
-  [1] Top-level let binding + comments
-  [2] Function definition (atomic, preserves signature)
-  [3] Type definition (atomic, preserves interface)
-  [4] Implementation blocks with context overlap
-
-Each chunk preserves:
-  - Type signatures
-  - Function signatures
-  - Import statements needed for context
-  - Comments and docstrings
-```
-
-## Hybrid Search
-
-The system implements dual search strategy for optimal results:
-
-### Vector Similarity Search
-
-```bash
-// Find semantically similar documents
-async fn vector_search(query: &str, top_k: usize) -> Vec<Document> {
-    let embedding = embed(query).await?;
-    
-    // L2 distance in SurrealDB
-    db.query("
-        SELECT *, vector::similarity::cosine(embedding, $embedding) AS score
-        FROM documents
-        WHERE embedding <~> $embedding
-        ORDER BY score DESC
-        LIMIT $top_k
-    ")
-    .bind(("embedding", embedding))
-    .bind(("top_k", top_k))
-    .await
-}
-```
-
-**Use case**: Semantic understanding of intent
-- Query: "How to configure PostgreSQL"
-- Finds: Documents about database configuration, examples, schemas
-
-### BM25 Keyword Search
-
-```bash
-// Find documents with matching keywords
-async fn keyword_search(query: &str, top_k: usize) -> Vec<Document> {
-    // BM25 full-text search in SurrealDB
-    db.query("
-        SELECT *, search::bm25(.) AS score
-        FROM documents
-        WHERE text @@ $query
-        ORDER BY score DESC
-        LIMIT $top_k
-    ")
-    .bind(("query", query))
-    .bind(("top_k", top_k))
-    .await
-}
-```
-
-**Use case**: Exact term matching
-- Query: "SurrealDB configuration"
-- Finds: Documents mentioning SurrealDB specifically
-
-### Hybrid Results
-
-```javascript
-async fn hybrid_search(
-    query: &str,
-    vector_weight: f32,
-    keyword_weight: f32,
-    top_k: usize,
-) -> Vec<Document> {
-    let vector_results = vector_search(query, top_k * 2).await?;
-    let keyword_results = keyword_search(query, top_k * 2).await?;
-    
-    let mut scored = HashMap::new();
-    
-    // Score from vector search
-    for (i, doc) in vector_results.iter().enumerate() {
-        *scored.entry(doc.id).or_insert(0.0) +=
-            vector_weight * (1.0 - (i as f32 / top_k as f32));
-    }
-    
-    // Score from keyword search
-    for (i, doc) in keyword_results.iter().enumerate() {
-        *scored.entry(doc.id).or_insert(0.0) +=
-            keyword_weight * (1.0 - (i as f32 / top_k as f32));
-    }
-    
-    // Return top-k by combined score
-    let mut results: Vec<_> = scored.into_iter().collect();
-| results.sort_by( | a, b | b.1.partial_cmp(&a.1).unwrap()); |
-| Ok(results.into_iter().take(top_k).map( | (id, _) | ...).collect()) |
-}
-```
-
-## Semantic Caching
-
-Reduces API calls by caching embeddings of repeated queries:
-
-```rust
-struct SemanticCache {
-    queries: Arc<DashMap<Vec<f32>, CachedResult>>,
-    similarity_threshold: f32,
-}
-
-impl SemanticCache {
-    async fn get(&self, query: &str) -> Option<CachedResult> {
-        let embedding = embed(query).await?;
-        
-        // Find cached query with similar embedding
-        // (cosine distance < threshold)
-        for entry in self.queries.iter() {
-            let distance = cosine_distance(&embedding, entry.key());
-            if distance < self.similarity_threshold {
-                return Some(entry.value().clone());
-            }
-        }
-        None
-    }
-    
-    async fn insert(&self, query: &str, result: CachedResult) {
-        let embedding = embed(query).await?;
-        self.queries.insert(embedding, result);
-    }
-}
-```
-
-**Benefits**:
-- 50-80% reduction in embedding API calls
-- Identical queries return in <10ms
-- Similar queries reuse cached context
-
-## Ingestion Workflow
-
-### Document Indexing
-
-```bash
-# Index all documentation
-provisioning ai index-docs provisioning/docs/src
-
-# Index schemas
-provisioning ai index-schemas provisioning/schemas
-
-# Index past deployments
-provisioning ai index-deployments workspaces/*/deployments
-
-# Watch directory for changes (development mode)
-provisioning ai watch docs provisioning/docs/src
-```
-
-### Programmatic Indexing
-
-```bash
-// In ai-service on startup
-async fn initialize_rag() -> Result<()> {
-    let rag = RAGSystem::new(&config.rag).await?;
-    
-    // Index documentation
-    let docs = load_markdown_docs("provisioning/docs/src")?;
-    for doc in docs {
-        rag.ingest_document(&doc).await?;
-    }
-    
-    // Index schemas
-    let schemas = load_nickel_schemas("provisioning/schemas")?;
-    for schema in schemas {
-        rag.ingest_schema(&schema).await?;
-    }
-    
-    Ok(())
-}
-```
-
-## Usage Examples
-
-### Query the RAG System
-
-```bash
-# Search for context-aware information
-provisioning ai query "How do I configure PostgreSQL with encryption?"
-
-# Get configuration template
-provisioning ai template "Describe production Kubernetes on AWS"
-
-# Interactive mode
-provisioning ai chat
-> What are the best practices for database backup?
-```
-
-### AI Service Integration
-
-```bash
-// AI service uses RAG to enhance generation
-async fn generate_config(user_request: &str) -> Result<String> {
-    // Retrieve relevant context
-    let context = rag.search(user_request, top_k=5).await?;
-    
-    // Build prompt with context
-    let prompt = build_prompt_with_context(user_request, &context);
-    
-    // Generate configuration
-    let config = llm.generate(&prompt).await?;
-    
-    // Validate against schemas
-    validate_nickel_config(&config)?;
-    
-    Ok(config)
-}
-```
-
-### Form Assistance Integration
-
-```bash
-// In typdialog-ai (JavaScript/TypeScript)
-async function suggestFieldValue(fieldName, currentInput) {
-    // Query RAG for similar configurations
-    const context = await rag.search(
-        `Field: ${fieldName}, Input: ${currentInput}`,
-        { topK: 3, semantic: true }
-    );
-    
-    // Generate suggestion using context
-    const suggestion = await ai.suggest({
-        field: fieldName,
-        input: currentInput,
-        context: context,
-    });
-    
-    return suggestion;
-}
-```
-
-## Performance Characteristics
-
-|  | Operation | Time | Cache Hit |  |
-|  | ----------- | ------ | ----------- |  |
-|  | Vector embedding | 200-500ms | N/A |  |
-|  | Vector search (cold) | 300-800ms | N/A |  |
-|  | Keyword search | 50-200ms | N/A |  |
-|  | Hybrid search | 500-1200ms | <100ms cached |  |
-|  | Semantic cache hit | 10-50ms | Always |  |
-
-**Typical query flow**:
-1. Embedding: 300ms
-2. Vector search: 400ms
-3. Keyword search: 100ms
-4. Ranking: 50ms
-5. **Total**: ~850ms (first call), <100ms (cached)
-
-## Configuration
-
-See [Configuration Guide](configuration.md) for detailed RAG setup:
-
-- LLM provider for embeddings
-- SurrealDB connection
-- Chunking strategies
-- Search weights and limits
-- Cache settings and TTLs
-
-## Limitations and Considerations
-
-### Document Freshness
-
-- RAG indexes static snapshots
-- Changes to documentation require re-indexing
-- Use watch mode during development
-
-### Token Limits
-
-- Large documents chunked to fit LLM context
-- Some context may be lost in chunking
-- Adjustable chunk size vs. context trade-off
-
-### Embedding Quality
-
-- Quality depends on embedding model
-- Domain-specific models perform better
-- Fine-tuning possible for specialized vocabularies
-
-## Monitoring and Debugging
-
-### Query Metrics
-
-```bash
-# View RAG search metrics
-provisioning ai metrics show rag
-
-# Analysis of search quality
-provisioning ai eval-rag --sample-queries 100
-```
-
-### Debug Mode
-
-```bash
-# In provisioning/config/ai.toml
-[ai.rag.debug]
-enabled = true
-log_embeddings = true      # Log embedding vectors
-log_search_scores = true   # Log relevance scores
-log_context_used = true    # Log context retrieved
-```

-## Cedar Policies
-
-### Policy Engine Setup
-
-```bash
-// File: provisioning/policies/ai-policies.cedar
-
-// Core principle: Least privilege
-// All actions denied by default unless explicitly allowed
-
-// Admin users can access all AI features
-permit(
-  principal == ?principal,
-  action == Action::"ai_generate_config",
-  resource == ?resource
-)
-when {
-  principal.role == "admin"
-};
-
-// Developers can use AI within their workspace
-permit(
-  principal == ?principal,
-  action in [
-    Action::"ai_query",
-    Action::"ai_generate_config",
-    Action::"ai_troubleshoot"
-  ],
-  resource == ?resource
-)
-when {
-  principal.role in ["developer", "senior_engineer"]
-  && principal.workspace == resource.workspace
-};
-
-// Operators can access troubleshooting and queries
-permit(
-  principal == ?principal,
-  action in [
-    Action::"ai_query",
-    Action::"ai_troubleshoot"
-  ],
-  resource == ?resource
-)
-when {
-  principal.role in ["operator", "devops"]
-};
-
-// Form assistance enabled for all authenticated users
-permit(
-  principal == ?principal,
-  action == Action::"ai_form_assistance",
-  resource == ?resource
-)
-when {
-  principal.authenticated == true
-};
-
-// Agents (when available) require explicit approval
-permit(
-  principal == ?principal,
-  action == Action::"ai_agent_execute",
-  resource == ?resource
-)
-when {
-  principal.role == "automation_admin"
-  && resource.requires_approval == true
-};
-
-// MCP tool access - restrictive by default
-permit(
-  principal == ?principal,
-  action == Action::"mcp_tool_call",
-  resource == ?resource
-)
-when {
-  principal.role == "admin"
-|  |  | (principal.role == "developer" && resource.tool in ["generate_config", "validate_config"]) |
-};
-
-// Cost control policies
-permit(
-  principal == ?principal,
-  action == Action::"ai_generate_config",
-  resource == ?resource
-)
-when {
-  // User must have remaining budget
-  principal.ai_budget_remaining_usd > resource.estimated_cost_usd
-  // Workspace must be under budget
-  && resource.workspace.ai_budget_remaining_usd > resource.estimated_cost_usd
-};
-```
-
-### Policy Best Practices
-
-1. **Explicit Allow**: Only allow specific actions, deny by default
-2. **Workspace Isolation**: Users can't access AI in other workspaces
-3. **Role-Based**: Use consistent role definitions
-4. **Cost-Aware**: Check budgets before operations
-5. **Audit Trail**: Log all policy decisions
-
-## Data Sanitization
-
-### Automatic PII Removal
-
-Before sending data to external LLMs, the system removes:
-
-```bash
-Patterns Removed:
-├─ Passwords: password="...", pwd=..., etc.
-├─ API Keys: api_key=..., api-key=..., etc.
-├─ Tokens: token=..., bearer=..., etc.
-├─ Email addresses: user@example.com (unless necessary for context)
-├─ Phone numbers: +1-555-0123 patterns
-├─ Credit cards: 4111-1111-1111-1111 patterns
-├─ SSH keys: -----BEGIN RSA PRIVATE KEY-----...
-└─ AWS/GCP/Azure: AKIA2..., AIza..., etc.
-```
-
-### Configuration
-
-```toml
-[ai.security]
-sanitize_pii = true
-sanitize_secrets = true
-
-# Custom redaction patterns
-redact_patterns = [
-  # Database passwords
-  "(?i)db[_-]?password\\s*[:=]\\s*'?[^'
-]+'?",
-  # Generic secrets
-  "(?i)secret\\s*[:=]\\s*'?[^'
-]+'?",
-  # API endpoints that shouldn't be logged
-  "https?://api[.-]secret\\..+",
-]
-
-# Exceptions (patterns NOT to redact)
-preserve_patterns = [
-  # Preserve example.com domain for docs
-  "example\\.com",
-  # Preserve placeholder emails
-  "user@example\\.com",
-]
-```
-
-### Example Sanitization
-
-**Before**:
-```bash
-Error configuring database:
-connection_string: postgresql://dbadmin:MySecurePassword123@prod-db.us-east-1.rds.amazonaws.com:5432/app
-api_key: sk-ant-abc123def456
-vault_token: hvs.CAESIyg7...
-```
-
-**After Sanitization**:
-```bash
-Error configuring database:
-connection_string: postgresql://dbadmin:[REDACTED]@prod-db.us-east-1.rds.amazonaws.com:5432/app
-api_key: [REDACTED]
-vault_token: [REDACTED]
-```
-
-## Secret Isolation
-
-### Never Access Secrets Directly
-
-AI cannot directly access secrets. Instead:
-
-```bash
-User wants: "Configure PostgreSQL with encrypted backups"
-  ↓
-AI generates: Configuration schema with placeholders
-  ↓
-User inserts: Actual secret values (connection strings, passwords)
-  ↓
-System encrypts: Secrets remain encrypted at rest
-  ↓
-Deployment: Uses secrets from secure store (Vault, AWS Secrets Manager)
-```
-
-### Secret Protection Rules
-
-1. **No Direct Access**: AI never reads from Vault/Secrets Manager
-2. **Never in Logs**: Secrets never logged or stored in cache
-3. **Sanitization**: All secrets redacted before sending to LLM
-4. **Encryption**: Secrets encrypted at rest and in transit
-5. **Audit Trail**: All access to secrets logged
-6. **TTL**: Temporary secrets auto-expire
-
-## Local Models Support
-
-### Air-Gapped Deployments
-
-For environments requiring zero external API calls:
-
-```bash
-# Deploy local Ollama with provisioning support
-docker run -d 
-  --name provisioning-ai 
-  -p 11434:11434 
-  -v ollama:/root/.ollama 
-  -e OLLAMA_HOST=0.0.0.0:11434 
-  ollama/ollama
-
-# Pull model
-ollama pull mistral
-ollama pull llama2-70b
-
-# Configure provisioning to use local model
-provisioning config edit ai
-
-[ai]
-provider = "local"
-model = "mistral"
-api_base = "[http://localhost:11434"](http://localhost:11434")
-```
-
-### Benefits
-
-- ✅ Zero external API calls
-- ✅ Full data privacy (no LLM vendor access)
-- ✅ Compliance with classified/regulated data
-- ✅ No API key exposure
-- ✅ Deterministic (same results each run)
-
-### Performance Trade-offs
-
-|  | Factor | Local | Cloud |  |
-|  | -------- | ------- | ------- |  |
-|  | Privacy | Excellent | Requires trust |  |
-|  | Cost | Free (hardware) | Per token |  |
-|  | Speed | 5-30s/response | 2-5s/response |  |
-|  | Quality | Good (70B models) | Excellent (Opus) |  |
-|  | Hardware | Requires GPU | None |  |
-
-## HSM Integration
-
-### Hardware Security Module Support
-
-For highly sensitive environments:
-
-```toml
-[ai.security.hsm]
-enabled = true
-provider = "aws-cloudhsm"  # or "thales", "yubihsm"
-
-[ai.security.hsm.aws]
-cluster_id = "cluster-123"
-customer_ca_cert = "/etc/provisioning/certs/customerCA.crt"
-server_cert = "/etc/provisioning/certs/server.crt"
-server_key = "/etc/provisioning/certs/server.key"
-```
-
-## Encryption
-
-### Data at Rest
-
-```toml
-[ai.security.encryption]
-enabled = true
-algorithm = "aes-256-gcm"
-key_derivation = "argon2id"
-
-# Key rotation
-key_rotation_enabled = true
-key_rotation_days = 90
-rotation_alert_days = 7
-
-# Encrypted storage
-cache_encryption = true
-log_encryption = true
-```
-
-### Data in Transit
-
-```bash
-All external LLM API calls:
-├─ TLS 1.3 (minimum)
-├─ Certificate pinning (optional)
-├─ Mutual TLS (with cloud providers)
-└─ No plaintext transmission
-```
-
-## Audit Logging
-
-### What Gets Logged
-
-```json
-{
-  "timestamp": "2025-01-13T10:30:45Z",

-provisioning audit log ai --from "2025-01-01" --to "2025-01-13"
-
-# Export for analysis
-provisioning audit export ai --format csv --output audit.csv
-
-# Full-text search
-provisioning audit search ai "error in database configuration"
-```
-
-## Compliance Frameworks
-
-### Built-in Compliance Checks
-
-```toml
-[ai.compliance]
-frameworks = ["pci-dss", "hipaa", "sox", "gdpr"]
-
-[ai.compliance.pci-dss]
-enabled = true
-# Requires encryption, audit logs, access controls
-
-[ai.compliance.hipaa]
-enabled = true
-# Requires local models, encrypted storage, audit logs
-
-[ai.compliance.gdpr]
-enabled = true
-# Requires data deletion, consent tracking, privacy by design
-```
-
-### Compliance Reports
-
-```bash
-# Generate compliance report
-provisioning audit compliance-report 
-  --framework pci-dss 
-  --period month 
-  --output report.pdf
-
-# Verify compliance
-provisioning audit verify-compliance 
-  --framework hipaa 
-  --verbose
-```
-
-## Security Best Practices
-
-### For Administrators
-
-1. **Rotate API Keys**: Every 90 days minimum
-2. **Monitor Budget**: Set up alerts at 80% and 90%
-3. **Review Policies**: Quarterly policy audit
-4. **Audit Logs**: Weekly review of AI operations
-5. **Update Models**: Use latest stable models
-6. **Test Recovery**: Monthly rollback drills
-
-### For Developers
-
-1. **Use Workspace Isolation**: Never share workspace access
-2. **Don't Log Secrets**: Use sanitization, never bypass it
-3. **Validate Outputs**: Always review AI-generated configs
-4. **Report Issues**: Security issues to `security-ai@company.com`
-5. **Stay Updated**: Follow security bulletins
-
-### For Operators
-
-1. **Monitor Costs**: Alert if exceeding 110% of budget
-2. **Watch Errors**: Unusual error patterns may indicate attacks
-3. **Check Audit Logs**: Unauthorized access attempts
-4. **Test Policies**: Periodically verify Cedar policies work
-5. **Backup Configs**: Secure backup of policy files
-
-## Incident Response
-
-### Compromised API Key
-
-```bash
-# 1. Immediately revoke key
-provisioning admin revoke-key ai-api-key-123
-
-# 2. Rotate key
-provisioning admin rotate-key ai 
-  --notify ops-team@company.com
-
-# 3. Audit usage since compromise
-provisioning audit log ai 
-  --since "2025-01-13T09:00:00Z" 
-  --api-key-id ai-api-key-123
-
-# 4. Review any generated configs from this period
-# Configs generated while key was compromised may need review
-```
-
-### Unauthorized Access
-
-```bash
-# Review Cedar policy logs
-provisioning audit log ai 
-  --decision deny 
-  --last-hour
-
-# Check for pattern
-provisioning audit search ai "authorization.*deny" 
-  --trend-analysis
-
-# Update policies if needed
-provisioning policy update ai-policies.cedar
-```

-  - Identifies failure phase (networking, database, k8s, etc.)
-  - Detects root cause (resource limits, configuration, timeout)
-  - Correlates with similar past failures
-  - Reviews deployment configuration
-        ↓
-AI generates report:
-  - Root cause explanation in plain English
-  - Configuration issues identified
-  - Suggested fixes with rationale
-  - Alternative solutions
-  - Links to relevant documentation
-        ↓
-Developer reviews and accepts:

-║ Why this happened:                                            ║
-║   Pod spec updated to 4CPU/8GB but node group wasn't        ║
-║   Node group still has t3.medium (too small)                 ║

-║ Solution Options:                                             ║
-║   1. Reduce pod resource requests to 2CPU/4GB (simpler)      ║
-║   2. Scale up node group to t3.large (2x cost, safer)        ║
-║   3. Use both: t3.large nodes + reduce pod requests          ║

-  │       └─ Alternative Solutions: 3 options
-```
-
-## Learning from Failures
-
-### Pattern Recognition
-
-The system learns common failure patterns:
-
-```bash
-Collected Patterns:
-├─ Database Timeouts (25% of failures)
-│  └─ Usually: Security group, connection pool, slow startup
-├─ Kubernetes Pod Failures (20%)
-│  └─ Usually: Insufficient resources, bad config
-├─ Network Connectivity (15%)
-│  └─ Usually: Security groups, routing, DNS
-└─ Other (40%)
-   └─ Various causes, each analyzed individually
-```
-
-### Improvement Tracking
-
-```bash
-# See patterns in your deployments
-provisioning ai analytics failures --period month
-
-Month Summary:
-  Total deployments: 50
-  Failed: 5 (10% failure rate)
-  
-  Common causes:
-  1. Security group rules (3 failures, 60%)
-  2. Resource limits (1 failure, 20%)
-  3. Configuration error (1 failure, 20%)
-  
-  Improvement opportunities:
-  - Pre-check security groups before deployment
-  - Add health checks for resource sizing
-  - Add configuration validation
-```
-
-## Configuration
-
-### Troubleshooting Settings
-
-```toml
-[ai.troubleshooting]
-enabled = true
-
-# Analysis depth
-default_depth = "deep"  # or "shallow" for speed
-max_analysis_time_seconds = 30
-
-# Features
-auto_analyze_failed_deployments = true
-generate_corrected_config = true
-suggest_prevention = true

-report_format = "markdown"  # or "json", "pdf"
-include_alternatives = true
-
-# Cost impact analysis
-estimate_fix_cost = true
-estimate_alternative_costs = true
-```
-
-### Failure Detection
-
-```toml
-[ai.troubleshooting.detection]
-# Monitor logs for these patterns
-watch_patterns = [
-  "error",
-  "timeout",
-  "failed",
-  "unable to",
-  "refused",
-  "denied",
-  "exceeded",
-  "quota",
-]
-
-# Minimum log lines before analyzing
-min_log_lines = 10
-
-# Time window for log collection
-log_window_seconds = 300
-```
-
-## Best Practices
-
-### For Effective Troubleshooting
-
-1. **Keep Detailed Logs**: Enable verbose logging in deployments
-2. **Include Context**: Share full logs, not just error snippet
-3. **Check Suggestions**: Review AI suggestions even if obvious
-4. **Learn Patterns**: Track recurring failures and address root cause
-5. **Update Configs**: Use corrected configs from AI, validate them
-
-### For Prevention
-
-1. **Use Health Checks**: Add database/service health checks
-2. **Test Before Deploy**: Use dry-run to catch issues early
-3. **Monitor Metrics**: Watch CPU/memory before failures occur
-4. **Review Policies**: Ensure security groups are correct
-5. **Document Changes**: When updating configs, note the change
-
-## Limitations
-
-### What AI Can Troubleshoot
-
-✅ Configuration errors
-✅ Resource limit problems
-✅ Networking/security group issues
-✅ Database connectivity problems
-✅ Deployment ordering issues
-✅ Common application errors
-✅ Performance problems
-
-### What Requires Human Review
-
-⚠️ Data corruption scenarios
-⚠️ Multi-failure cascades
-⚠️ Unclear error messages
-⚠️ Custom application code failures
-⚠️ Third-party service issues
-⚠️ Physical infrastructure failures

+      cluster_name: $input.name
+      backup_interval: "daily"
+
+output:
+  cluster_name: string
+  cluster_id: string
+  kubeconfig_path: string
+  monitoring_url: string
+```
+
+**Usage**:
+
+```bash
+# Type-check agent
+typedialog ag check deploy-k8s.agent.yaml
+
+# Run agent interactively
+typedialog ag run deploy-k8s.agent.yaml \
+  --provider upcloud \
+  --name production-k8s \
+  --nodes 5 \
+  --node-config '{"cpu": 8, "memory": 32, "disk": 100}'
+
+# Transpile to Nickel
+typedialog ag transpile deploy-k8s.agent.yaml > deploy-k8s.ncl
+
+# Execute generated Nickel
+provisioning apply deploy-k8s.ncl
+```
+
+**Generated Nickel Output** (example):
+
+```nickel
+{
+  metadata = {
+    agent = "deploy-k8s"
+    version = "1.0"
+    generated_at = "2026-01-16T01:47:00Z"
+  }
+
+  resources = {
+    network = {
+      provider = "upcloud"
+      vpc = { cidr = "10.0.0.0/16" }
+    }
+
+    compute = {
+      provider = "upcloud"
+      nodes = [
+        { count = 5, cpu = 8, memory = 32, disk = 100 }
+      ]
+    }
+
+    kubernetes = {
+      version = "1.28.0"
+      high_availability = true
+      monitoring = {
+        enabled = true
+        stack = "prometheus-grafana"
+      }
+      backup = {
+        enabled = true
+        interval = "daily"
+      }
+    }
+  }
+}
+```
+
+**Agent Features**:
+
+| Feature | Purpose |
+| --- | --- |
+| **Dependencies** | Declare task ordering (depends_on) |
+| **Parallelism** | Run independent tasks in parallel |
+| **Conditionals** | Execute tasks based on input conditions |

+
+```http
+Authorization: Bearer <jwt-token>
 ```
 
-See [REST API](rest-api.md) for complete endpoint documentation.
+**Request Format**:
+
+```http
+Content-Type: application/json
+```
+
+**Response Format**:
+
+```json
+{
+  "status": "succes| s error",
+  "data": { ... },
+  "message": "Human-readable message",
+  "timestamp": "2026-01-16T10:30:00Z"

+    "message": "Error description",
+    "details": { ... }
+  },
+  "timestamp": "2026-01-16T10:30:00Z"
+}
+```
+
+### CLI Command Patterns
+
+All CLI commands follow consistent patterns:
+
+**Common Flags**:
+
+- `--yes` - Skip confirmation prompts
+- `--check` - Dry-run mode, show what would happen
+- `--wait` - Wait for operation completion
+- `--format jso| n yam| l table` - Output format

+provisioning taskserv install kubernetes --cluster prod
+provisioning workflow submit deploy.ncl --wait
+```
+
+### Library Function Signatures
+
+Nushell library functions follow consistent signatures:
+
+**Parameter Order**:
+
+1. Required positional parameters
+2. Optional positional parameters
+3. Named parameters (flags)
+
+**Return Values**:
+
+- Success: Returns data structure (record, table, list)
+- Error: Throws error with structured message
+
+**Example**:
+
+```nushell
+def create-server [
+  name: string           # Required: server name
+  --plan: string = "medium"  # Optional: server plan
+  --wait                 # Optional: wait flag
+] {
+  # Implementation
+}
+```
+
+## API Versioning
+
+The Provisioning platform uses semantic versioning for APIs:
+
+- **Major version** - Breaking changes to API contracts
+- **Minor version** - Backwards-compatible additions
+- **Patch version** - Backwards-compatible bug fixes
+
+**Current API Version**: v1.0.0
+
+**Version Compatibility**:
+
+- REST API includes version in URL: `/api/v1/servers`
+- CLI maintains backwards compatibility across minor versions
+- Libraries use semantic import versioning
+
+## Rate Limiting
+
+REST API endpoints implement rate limiting to ensure platform stability:
+
+- **Default Limit**: 100 requests per minute per API key
+- **Burst Limit**: 20 requests per second
+- **Headers**: Rate limit information in response headers
+
+```http
+X-RateLimit-Limit: 100
+X-RateLimit-Remaining: 95
+X-RateLimit-Reset: 1642334400
+```
+
+## Authentication
+
+All APIs require authentication except public health endpoints.
+
+**Supported Methods**:
+
+- **JWT Tokens** - Primary authentication method
+- **API Keys** - For service-to-service integration
+- **MFA** - Multi-factor authentication for sensitive operations
+
+**Token Management**:
+
+```bash
+# Login and obtain token
+provisioning auth login --user admin
+
+# Use token in requests
+curl -H "Authorization: Bearer $TOKEN"  [https://api/v1/servers](https://api/v1/servers)
+```
+
+See [Authentication Guide](../security/authentication.md) for complete details.
+
+## API Discovery
+
+Discover available APIs programmatically:
+
+**REST API**:
+
+```bash
+# Get API specification (OpenAPI)
+curl  [https://api/v1/openapi.json](https://api/v1/openapi.json)
+```
+
+**CLI**:
+
+```bash
+# List all commands
+provisioning help --all
+
+# Get command details
+provisioning server help
+```
+
+**Libraries**:
+
+```nushell
+# List available modules
+use lib_provisioning *
+$nu.scope.commands | where is_custom
+```

-# Path Resolution API
-
-This document describes the path resolution system used throughout the provisioning infrastructure for discovering configurations, extensions, and
-resolving workspace paths.
-
-## Overview
-
-The path resolution system provides a hierarchical and configurable mechanism for:
-
-- Configuration file discovery and loading
-- Extension discovery (providers, task services, clusters)
-- Workspace and project path management
-- Environment variable interpolation
-- Cross-platform path handling
-
-## Configuration Resolution Hierarchy
-
-The system follows a specific hierarchy for loading configuration files:
-
-```toml
-1. System defaults      (config.defaults.toml)
-2. User configuration   (config.user.toml)
-3. Project configuration (config.project.toml)
-4. Infrastructure config (infra/config.toml)
-5. Environment config   (config.{env}.toml)
-6. Runtime overrides    (CLI arguments, ENV vars)
-```
-
-### Configuration Search Paths
-
-The system searches for configuration files in these locations:
-
-```toml
-# Default search paths (in order)
-/usr/local/provisioning/config.defaults.toml
-$HOME/.config/provisioning/config.user.toml
-$PWD/config.project.toml
-$PROVISIONING_KLOUD_PATH/config.infra.toml
-$PWD/config.{PROVISIONING_ENV}.toml
-```
-
-## Path Resolution API
-
-### Core Functions
-
-#### `resolve-config-path(pattern: string, search_paths: list<string>) -> string`
-
-Resolves configuration file paths using the search hierarchy.
-
-**Parameters:**
-
-- `pattern`: File pattern to search for (for example, "config.*.toml")
-- `search_paths`: Additional paths to search (optional)
-
-**Returns:**
-
-- Full path to the first matching configuration file
-- Empty string if no file found
-
-**Example:**
-
-```bash
-use path-resolution.nu *
-let config_path = (resolve-config-path "config.user.toml" [])
-# Returns: "/home/user/.config/provisioning/config.user.toml"
-```
-
-#### `resolve-extension-path(type: string, name: string) -> record`
-
-Discovers extension paths (providers, taskservs, clusters).
-
-**Parameters:**
-
-- `type`: Extension type ("provider", "taskserv", "cluster")
-- `name`: Extension name (for example, "upcloud", "kubernetes", "buildkit")
-

-import json
-
-class PathResolver:
-    def __init__(self, provisioning_path="/usr/local/bin/provisioning"):
-        self.cmd = provisioning_path
-
-    def get_paths(self):
-        result = subprocess.run([
-            "nu", "-c", f"use {self.cmd} *; show-config --section=paths --format=json"
-        ], capture_output=True, text=True)
-        return json.loads(result.stdout)
-
-    def discover_providers(self):
-        result = subprocess.run([
-            "nu", "-c", f"use {self.cmd} *; discover providers --format=json"
-        ], capture_output=True, text=True)
-        return json.loads(result.stdout)
-
-# Usage
-resolver = PathResolver()
-paths = resolver.get_paths()
-providers = resolver.discover_providers()
-```
-
-### JavaScript/Node.js Integration
-
-```javascript
-const { exec } = require('child_process');
-const util = require('util');
-const execAsync = util.promisify(exec);
-
-class PathResolver {
-  constructor(provisioningPath = '/usr/local/bin/provisioning') {
-    this.cmd = provisioningPath;
-  }
-
-  async getPaths() {
-    const { stdout } = await execAsync(
-      `nu -c "use ${this.cmd} *; show-config --section=paths --format=json"`
-    );
-    return JSON.parse(stdout);
-  }
-
-  async discoverExtensions(type) {
-    const { stdout } = await execAsync(
-      `nu -c "use ${this.cmd} *; discover ${type} --format=json"`
-    );
-    return JSON.parse(stdout);
-  }
-}
-
-// Usage
-const resolver = new PathResolver();
-const paths = await resolver.getPaths();
-const providers = await resolver.discoverExtensions('providers');
-```
-
-## Error Handling
-
-### Common Error Scenarios
-
-1. **Configuration File Not Found**
-
-   ```nushell
-   Error: Configuration file not found in search paths
-   Searched: ["/usr/local/provisioning/config.defaults.toml", ...]
-   ```
-
-1. **Extension Not Found**
-
-   ```nushell
-   Error: Provider 'missing-provider' not found
-   Available providers: ["upcloud", "aws", "local"]
-   ```
-
-2. **Invalid Path Template**
-
-   ```nushell
-   Error: Invalid template variable: {{invalid.var}}
-   Valid variables: ["paths.*", "env.*", "now.*", "git.*"]
-   ```
-
-3. **Environment Not Found**
-
-   ```nushell
-   Error: Environment 'staging' not configured
-   Available environments: ["dev", "test", "prod"]
-   ```
-
-### Error Recovery
-
-The system provides graceful fallbacks:
-
-- Missing configuration files use system defaults
-- Invalid paths fall back to safe defaults
-- Extension discovery continues if some paths are inaccessible
-- Environment detection falls back to 'local' if detection fails
-
-## Performance Considerations
-
-### Best Practices
-
-1. **Use Path Caching**: Enable caching for frequently accessed paths
-2. **Batch Discovery**: Discover all extensions at once rather than individually
-3. **Lazy Loading**: Load extension configurations only when needed
-4. **Environment Detection**: Cache environment detection results
-
-### Monitoring
-
-Monitor path resolution performance:
-
-```bash
-# Get resolution statistics
-provisioning debug path-stats
-
-# Monitor cache performance
-provisioning debug cache-stats
-
-# Profile path resolution
-provisioning debug profile-paths
-```
-
-## Security Considerations
-
-### Path Traversal Protection
-
-The system includes protections against path traversal attacks:
-
-- All paths are normalized and validated
-- Relative paths are resolved within safe boundaries
-- Symlinks are validated before following
-
-### Access Control
-
-Path resolution respects file system permissions:
-
-- Configuration files require read access
-- Extension directories require read/execute access
-- Workspace directories may require write access for operations
-
-This path resolution API provides a comprehensive and flexible system for managing the complex path requirements of multi-provider, multi-environment
-infrastructure provisioning.

-# Provider API Reference
-
-API documentation for creating and using infrastructure providers.
-
-## Overview
-
-Providers handle cloud-specific operations and resource provisioning. The provisioning platform supports multiple cloud providers through a unified API.
-
-## Supported Providers
-
-- **UpCloud** - European cloud provider
-- **AWS** - Amazon Web Services
-- **Local** - Local development environment
-
-## Provider Interface
-
-All providers must implement the following interface:
-
-### Required Functions
-
-```bash
-# Provider initialization
-export def init [] -> record { ... }
-
-# Server operations
-export def create-servers [plan: record] -> list { ... }
-export def delete-servers [ids: list] -> bool { ... }
-export def list-servers [] -> table { ... }
-
-# Resource information
-export def get-server-plans [] -> table { ... }
-export def get-regions [] -> list { ... }
-export def get-pricing [plan: string] -> record { ... }
-```
-
-### Provider Configuration
-
-Each provider requires configuration in Nickel format:
-
-```nickel
-# Example: UpCloud provider configuration
-{
-  provider = {
-    name = "upcloud",
-    type = "cloud",
-    enabled = true,
-    config = {
-      username = "{{env.UPCLOUD_USERNAME}}",
-      password = "{{env.UPCLOUD_PASSWORD}}",
-      default_zone = "de-fra1",
-    },
-  }
-}
-```
-

-
-## Provider Discovery
-
-Providers are automatically discovered from:
-
-- `provisioning/extensions/providers/*/nu/*.nu`
-- User workspace: `workspace/extensions/providers/*/nu/*.nu`
-
-```nushell
-# Discover available providers
-provisioning module discover providers
-
-# Load provider
-provisioning module load providers workspace my-provider
-```
-
-## Provider API Examples
-
-### Create Servers
-
-```bash
-use my_provider.nu *
-
-let plan = {
-    count: 3
-    size: "medium"
-    zone: "us-east-1"
-}
-
-create-servers $plan
-```
-
-### List Servers
-
-```bash
-list-servers | where status == "running" | select hostname ip_address
-```
-
-### Get Pricing
-
-```bash
-get-pricing "small" | to yaml
-```
-
-## Testing Providers
-
-Use the test environment system to test providers:
-
-```bash
-# Test provider without real resources
-provisioning test env single my-provider --check
-```

-# WebSocket API Reference
-
-This document provides comprehensive documentation for the WebSocket API used for real-time monitoring, event streaming, and live updates in
-provisioning.
-
-## Overview
-
-The WebSocket API enables real-time communication between clients and the provisioning orchestrator, providing:
-
-- Live workflow progress updates
-- System health monitoring
-- Event streaming
-- Real-time metrics
-- Interactive debugging sessions
-
-## WebSocket Endpoints
-
-### Primary WebSocket Endpoint
-
-#### `ws://localhost:9090/ws`
-
-The main WebSocket endpoint for real-time events and monitoring.
-
-**Connection Parameters:**
-
-- `token`: JWT authentication token (required)
-- `events`: Comma-separated list of event types to subscribe to (optional)
-- `batch_size`: Maximum number of events per message (default: 10)
-- `compression`: Enable message compression (default: false)
-
-**Example Connection:**
-
-```javascript
-const ws = new WebSocket('ws://localhost:9090/ws?token=jwt-token&events=task,batch,system');
-```
-
-### Specialized WebSocket Endpoints
-
-#### `ws://localhost:9090/metrics`
-
-Real-time metrics streaming endpoint.
-
-**Features:**
-
-- Live system metrics
-- Performance data
-- Resource utilization
-- Custom metric streams
-
-#### `ws://localhost:9090/logs`
-
-Live log streaming endpoint.
-
-**Features:**
-
-- Real-time log tailing
-- Log level filtering
-- Component-specific logs
-- Search and filtering
-
-## Authentication
-
-### JWT Token Authentication
-
-All WebSocket connections require authentication via JWT token:
-
-```bash
-// Include token in connection URL
-const ws = new WebSocket('ws://localhost:9090/ws?token=' + jwtToken);
-
-// Or send token after connection
-ws.onopen = function() {
-  ws.send(JSON.stringify({
-    type: 'auth',
-    token: jwtToken
-  }));
-};
-```
-
-### Connection Authentication Flow
-
-1. **Initial Connection**: Client connects with token parameter
-2. **Token Validation**: Server validates JWT token
-3. **Authorization**: Server checks token permissions
-4. **Subscription**: Client subscribes to event types
-5. **Event Stream**: Server begins streaming events
-

-
-## Event Filtering and Subscriptions
-
-### Client-Side Filtering
-
-```bash
-// Subscribe to specific event types
-ws.subscribe(['TaskStatusChanged', 'WorkflowProgressUpdate']);
-
-// Subscribe with filters
-ws.send({
-  type: 'subscribe',
-  events: ['TaskStatusChanged'],
-  filters: {
-    task_name: 'create_servers',
-    status: ['Running', 'Completed', 'Failed']
-  }
-});
-
-// Advanced filtering
-ws.send({
-  type: 'subscribe',
-  events: ['LogEntry'],
-  filters: {
-    level: ['ERROR', 'WARN'],
-    component: ['server-manager', 'batch-coordinator'],
-    since: '2025-09-26T10:00:00Z'
-  }
-});
-```
-
-### Server-Side Event Filtering
-
-Events can be filtered on the server side based on:
-
-- User permissions and roles
-- Event type subscriptions
-- Custom filter criteria
-- Rate limiting
-
-## Error Handling and Reconnection
-
-### Connection Errors
-
-```bash
-ws.on('error', (error) => {
-  console.error('WebSocket error:', error);
-
-  // Handle specific error types
-  if (error.code === 1006) {
-    // Abnormal closure, attempt reconnection
-    setTimeout(() => ws.connect(), 5000);
-  } else if (error.code === 1008) {
-    // Policy violation, check token
-    refreshTokenAndReconnect();
-  }
-});
-
-ws.on('disconnected', (event) => {
-  console.log(`WebSocket disconnected: ${event.code} - ${event.reason}`);
-
-  // Handle different close codes
-  switch (event.code) {
-    case 1000: // Normal closure
-      console.log('Connection closed normally');
-      break;
-    case 1001: // Going away
-      console.log('Server is shutting down');
-      break;
-    case 4001: // Custom: Token expired
-      refreshTokenAndReconnect();
-      break;
-    default:
-      // Attempt reconnection for other errors
-      if (shouldReconnect()) {
-        scheduleReconnection();
-      }
-  }
-});
-```
-
-### Heartbeat and Keep-Alive
-
-```javascript
-class ProvisioningWebSocket {
-  constructor(baseUrl, token, options = {}) {
-    // ... existing code ...
-    this.heartbeatInterval = options.heartbeatInterval || 30000;
-    this.heartbeatTimer = null;
-  }
-
-  connect() {
-    // ... existing connection code ...
-
-    this.ws.onopen = (event) => {
-      console.log('WebSocket connected');
-      this.startHeartbeat();
-      this.emit('connected', event);
-    };
-
-    this.ws.onclose = (event) => {
-      this.stopHeartbeat();
-      // ... existing close handling ...
-    };
-  }
-
-  startHeartbeat() {
-    this.heartbeatTimer = setInterval(() => {
-      if (this.ws && this.ws.readyState === WebSocket.OPEN) {
-        this.send({ type: 'ping' });
-      }
-    }, this.heartbeatInterval);
-  }
-
-  stopHeartbeat() {
-    if (this.heartbeatTimer) {
-      clearInterval(this.heartbeatTimer);
-      this.heartbeatTimer = null;
-    }
-  }
-
-  handleMessage(message) {
-    if (message.type === 'pong') {
-      // Heartbeat response received
-      return;
-    }
-
-    // ... existing message handling ...
-  }
-}
-```
-
-## Performance Considerations
-
-### Message Batching
-
-To improve performance, the server can batch multiple events into single WebSocket messages:
-
-```json
-{
-  "type": "batch",
-  "timestamp": "2025-09-26T10:00:00Z",
-  "events": [
-    {
-      "event_type": "TaskStatusChanged",
-      "data": { ... }
-    },
-    {
-      "event_type": "WorkflowProgressUpdate",
-      "data": { ... }
-    }
-  ]
-}
-```
-
-### Compression
-
-Enable message compression for large events:
-
-```javascript
-const ws = new WebSocket('ws://localhost:9090/ws?token=jwt&compression=true');
-```
-
-### Rate Limiting
-
-The server implements rate limiting to prevent abuse:
-
-- Maximum connections per user: 10
-- Maximum messages per second: 100
-- Maximum subscription events: 50
-
-## Security Considerations
-
-### Authentication and Authorization
-
-- All connections require valid JWT tokens
-- Tokens are validated on connection and periodically renewed
-- Event access is controlled by user roles and permissions
-
-### Message Validation
-
-- All incoming messages are validated against schemas
-- Malformed messages are rejected
-- Rate limiting prevents DoS attacks
-
-### Data Sanitization
-
-- All event data is sanitized before transmission
-- Sensitive information is filtered based on user permissions
-- PII and secrets are never transmitted
-
-This WebSocket API provides a robust, real-time communication channel for monitoring and managing provisioning with comprehensive security and
-performance features.

-# ADR-001: Project Structure Decision
-
-## Status
-
-Accepted
-
-## Context
-
-Provisioning had evolved from a monolithic structure into a complex system with mixed organizational patterns. The original structure had multiple issues:
-
-1. **Provider-specific code scattered**: Cloud provider implementations were mixed with core logic
-2. **Task services fragmented**: Infrastructure services lacked consistent structure
-3. **Domain boundaries unclear**: No clear separation between core, providers, and services
-4. **Development artifacts mixed with distribution**: User-facing tools mixed with development utilities
-5. **Deep call stack limitations**: Nushell's runtime limitations required architectural solutions
-6. **Configuration complexity**: 200+ environment variables across 65+ files needed systematic organization
-
-The system needed a clear, maintainable structure that supports:
-
-- Multi-provider infrastructure provisioning (AWS, UpCloud, local)
-- Modular task services (Kubernetes, container runtimes, storage, networking)
-- Clear separation of concerns
-- Hybrid Rust/Nushell architecture
-- Configuration-driven workflows
-- Clean distribution without development artifacts
-
-## Decision
-
-Adopt a **domain-driven hybrid structure** organized around functional boundaries:
-
-```bash
-src/
-├── core/           # Core system and CLI entry point
-├── platform/       # High-performance coordination layer (Rust orchestrator)
-├── orchestrator/   # Legacy orchestrator location (to be consolidated)
-├── provisioning/   # Main provisioning with domain modules
-├── control-center/ # Web UI management interface
-├── tools/          # Development and utility tools
-└── extensions/     # Plugin and extension framework
-```
-
-### Key Structural Principles
-
-1. **Domain Separation**: Each major component has clear boundaries and responsibilities
-2. **Hybrid Architecture**: Rust for performance-critical coordination, Nushell for business logic
-3. **Provider Abstraction**: Standardized interfaces across cloud providers
-4. **Service Modularity**: Reusable task services with consistent structure
-5. **Clean Distribution**: Development tools separated from user-facing components
-6. **Configuration Hierarchy**: Systematic config management with interpolation support
-
-### Domain Organization
-
-- **Core**: CLI interface, library modules, and common utilities
-- **Platform**: High-performance Rust orchestrator for workflow coordination
-- **Provisioning**: Main business logic with providers, task services, and clusters
-- **Control Center**: Web-based management interface
-- **Tools**: Development utilities and build systems
-- **Extensions**: Plugin framework and custom extensions
-
-## Consequences
-
-### Positive
-
-- **Clear Boundaries**: Each domain has well-defined responsibilities and interfaces
-- **Scalable Growth**: New providers and services can be added without structural changes
-- **Development Efficiency**: Developers can focus on specific domains without system-wide knowledge
-- **Clean Distribution**: Users receive only necessary components without development artifacts
-- **Maintenance Clarity**: Issues can be isolated to specific domains
-- **Hybrid Benefits**: Leverage Rust performance where needed while maintaining Nushell productivity
-- **Configuration Consistency**: Systematic approach to configuration management across all domains
-
-### Negative
-
-- **Migration Complexity**: Required systematic migration of existing components
-- **Learning Curve**: New developers need to understand domain boundaries
-- **Coordination Overhead**: Cross-domain features require careful interface design
-- **Path Management**: More complex path resolution with domain separation
-- **Build Complexity**: Multiple domains require coordinated build processes
-
-### Neutral
-
-- **Development Patterns**: Each domain may develop its own patterns within architectural guidelines
-- **Testing Strategy**: Domain-specific testing strategies while maintaining integration coverage
-- **Documentation**: Domain-specific documentation with clear cross-references
-
-## Alternatives Considered
-
-### Alternative 1: Monolithic Structure
-
-Keep all code in a single flat structure with minimal organization.
-**Rejected**: Would not solve maintainability or scalability issues. Continued technical debt accumulation.
-
-### Alternative 2: Microservice Architecture
-
-Split into completely separate services with network communication.
-**Rejected**: Overhead too high for single-machine deployment use case. Would complicate installation and configuration.
-
-### Alternative 3: Language-Based Organization
-
-Organize by implementation language (rust/, nushell/, kcl/).
-**Rejected**: Does not align with functional boundaries. Cross-cutting concerns would be scattered.
-
-### Alternative 4: Feature-Based Organization
-
-Organize by user-facing features (servers/, clusters/, networking/).
-**Rejected**: Would duplicate cross-cutting infrastructure and provider logic across features.
-
-### Alternative 5: Layer-Based Architecture
-
-Organize by architectural layers (presentation/, business/, data/).
-**Rejected**: Does not align with domain complexity. Infrastructure provisioning has different layering needs.

-# ADR-002: Distribution Strategy
-
-## Status
-
-Accepted
-
-## Context
-
-Provisioning needed a clean distribution strategy that separates user-facing tools from development artifacts. Key challenges included:
-
-1. **Development Artifacts Mixed with Production**: Build tools, test files, and development utilities scattered throughout user directories
-2. **Complex Installation Process**: Users had to navigate through development-specific directories and files
-3. **Unclear User Experience**: No clear distinction between what users need versus what developers need
-4. **Configuration Complexity**: Multiple configuration files with unclear precedence and purpose
-5. **Workspace Pollution**: User workspaces contained development-only files and directories
-6. **Path Resolution Issues**: Complex path resolution logic mixing development and production concerns
-
-The system required a distribution strategy that provides:
-
-- Clean user experience without development artifacts
-- Clear separation between user and development tools
-- Simplified configuration management
-- Consistent installation and deployment patterns
-- Maintainable development workflow
-
-## Decision
-
-Implement a **layered distribution strategy** with clear separation between development and user environments:
-
-### Distribution Layers
-
-1. **Core Distribution Layer**: Essential user-facing components
-   - Main CLI tools and libraries
-   - Configuration templates and defaults
-   - Provider implementations
-   - Task service definitions
-
-2. **Development Layer**: Development-specific tools and artifacts
-   - Build scripts and development utilities
-   - Test suites and validation tools
-   - Development configuration templates
-   - Code generation tools
-
-3. **Workspace Layer**: User-specific customization and data
-   - User configurations and overrides
-   - Local state and cache files
-   - Custom extensions and plugins
-   - User-specific templates and workflows
-
-### Distribution Structure
-
-```bash
-# User Distribution
-/usr/local/bin/
-├── provisioning              # Main CLI entry point
-└── provisioning-*           # Supporting utilities
-
-/usr/local/share/provisioning/
-├── core/                    # Core libraries and modules
-├── providers/               # Provider implementations
-├── taskservs/              # Task service definitions
-├── templates/              # Configuration templates
-└── config.defaults.toml    # System-wide defaults
-
-# User Workspace
-~/workspace/provisioning/
-├── config.user.toml        # User preferences
-├── infra/                  # User infrastructure definitions
-├── extensions/             # User extensions
-└── cache/                  # Local cache and state
-
-# Development Environment
-<project-root>/
-├── src/                    # Source code
-├── scripts/                # Development tools
-├── tests/                  # Test suites
-└── tools/                  # Build and development utilities
-```
-
-### Key Distribution Principles
-
-1. **Clean Separation**: Development artifacts never appear in user installations
-2. **Hierarchical Configuration**: Clear precedence from system defaults to user overrides
-3. **Self-Contained User Tools**: Users can work without accessing development directories
-4. **Workspace Isolation**: User data and customizations isolated from system installation
-5. **Consistent Paths**: Predictable path resolution across different installation types
-6. **Version Management**: Clear versioning and upgrade paths for distributed components
-
-## Consequences
-
-### Positive
-
-- **Clean User Experience**: Users interact only with production-ready tools and interfaces
-- **Simplified Installation**: Clear installation process without development complexity
-- **Workspace Isolation**: User customizations don't interfere with system installation
-- **Development Efficiency**: Developers can work with full toolset without affecting users
-- **Configuration Clarity**: Clear hierarchy and precedence for configuration settings
-- **Maintainable Updates**: System updates don't affect user customizations
-- **Path Simplicity**: Predictable path resolution without development-specific logic
-- **Security Isolation**: User workspace separated from system components
-
-### Negative
-
-- **Distribution Complexity**: Multiple distribution targets require coordinated build processes
-- **Path Management**: More complex path resolution logic to support multiple layers
-- **Migration Overhead**: Existing users need to migrate to new workspace structure
-- **Documentation Burden**: Need clear documentation for different user types
-- **Testing Complexity**: Must validate distribution across different installation scenarios
-
-### Neutral
-
-- **Development Patterns**: Different patterns for development versus production deployment
-- **Configuration Strategy**: Layer-specific configuration management approaches
-- **Tool Integration**: Different integration patterns for development versus user tools
-
-## Alternatives Considered
-
-### Alternative 1: Monolithic Distribution
-
-Ship everything (development and production) in single package.
-**Rejected**: Creates confusing user experience and bloated installations. Mixes development concerns with user needs.
-
-### Alternative 2: Container-Only Distribution
-
-Package entire system as container images only.
-**Rejected**: Limits deployment flexibility and complicates local development workflows. Not suitable for all use cases.
-
-### Alternative 3: Source-Only Distribution
-
-Require users to build from source with development environment.
-**Rejected**: Creates high barrier to entry and mixes user concerns with development complexity.
-
-### Alternative 4: Plugin-Based Distribution
-
-Minimal core with everything else as downloadable plugins.
-**Rejected**: Would fragment essential functionality and complicate initial setup. Network dependency for basic functionality.
-
-### Alternative 5: Environment-Based Distribution
-
-Use environment variables to control what gets installed.
-**Rejected**: Creates complex configuration matrix and potential for inconsistent installations.
-
-## Implementation Details
-
-### Distribution Build Process
-
-1. **Core Layer Build**: Extract essential user components from source
-2. **Template Processing**: Generate configuration templates with proper defaults
-3. **Path Resolution**: Generate path resolution logic for different installation types
-4. **Documentation Generation**: Create user-specific documentation excluding development details
-5. **Package Creation**: Build distribution packages for different platforms
-6. **Validation Testing**: Test installations in clean environments
-
-### Configuration Hierarchy
-
-```toml
-System Defaults (lowest precedence)
-└── User Configuration
-    └── Project Configuration
-        └── Infrastructure Configuration
-            └── Environment Configuration
-                └── Runtime Configuration (highest precedence)
-```
-
-### Workspace Management
-
-- **Automatic Creation**: User workspace created on first run
-- **Template Initialization**: Workspace populated with configuration templates
-- **Version Tracking**: Workspace tracks compatible system versions
-- **Migration Support**: Automatic migration between workspace versions

-# ADR-003: Workspace Isolation
-
-## Status
-
-Accepted
-
-## Context
-
-Provisioning required a clear strategy for managing user-specific data, configurations,
-and customizations separate from system-wide installations. Key challenges included:
-
-1. **Configuration Conflicts**: User settings mixed with system defaults, causing unclear precedence
-2. **State Management**: User state (cache, logs, temporary files) scattered across filesystem
-3. **Customization Isolation**: User extensions and customizations affecting system behavior
-4. **Multi-User Support**: Multiple users on same system interfering with each other
-5. **Development vs Production**: Developer needs different from end-user needs
-6. **Path Resolution Complexity**: Complex logic to locate user-specific resources
-7. **Backup and Migration**: Difficulty backing up and migrating user-specific settings
-8. **Security Boundaries**: Need clear separation between system and user-writable areas
-
-The system needed workspace isolation that provides:
-
-- Clear separation of user data from system installation
-- Predictable configuration precedence and inheritance
-- User-specific customization without system impact
-- Multi-user support on shared systems
-- Easy backup and migration of user settings
-- Security isolation between system and user areas
-
-## Decision
-
-Implement **isolated user workspaces** with clear boundaries and hierarchical configuration:
-
-### Workspace Structure
-
-```bash
-~/workspace/provisioning/           # User workspace root
-├── config/
-│   ├── user.toml                  # User preferences and overrides
-│   ├── environments/              # Environment-specific configs
-│   │   ├── dev.toml

-├── extensions/                    # User-installed extensions
-│   ├── providers/                 # Custom providers
-│   ├── taskservs/                 # Custom task services
-│   └── plugins/                   # User plugins
-├── templates/                     # User-specific templates
-├── cache/                         # Local cache and temporary data
-│   ├── provider-cache/            # Provider API cache

-│   └── build-cache/               # Build and generation cache
-├── logs/                          # User-specific logs
-├── state/                         # Local state files
-└── backups/                       # Automatic workspace backups
-```
-
-### Configuration Hierarchy (Precedence Order)
-
-1. **Runtime Parameters** (command line, environment variables)
-2. **Environment Configuration** (`config/environments/{env}.toml`)
-3. **Infrastructure Configuration** (`infra/{name}/config.toml`)
-4. **Project Configuration** (project-specific settings)
-5. **User Configuration** (`config/user.toml`)
-6. **System Defaults** (system-wide defaults)
-
-### Key Isolation Principles
-
-1. **Complete Isolation**: User workspace completely independent of system installation
-2. **Hierarchical Inheritance**: Clear configuration inheritance with user overrides
-3. **Security Boundaries**: User workspace in user-writable area only
-4. **Multi-User Safe**: Multiple users can have independent workspaces
-5. **Portable**: Entire user workspace can be backed up and restored
-6. **Version Independent**: Workspace compatible across system version upgrades
-7. **Extension Safe**: User extensions cannot affect system behavior
-8. **State Isolation**: All user state contained within workspace
-
-## Consequences
-
-### Positive
-
-- **User Independence**: Users can customize without affecting system or other users
-- **Configuration Clarity**: Clear hierarchy and precedence for all configuration
-- **Security Isolation**: User modifications cannot compromise system installation
-- **Easy Backup**: Complete user environment can be backed up and restored
-- **Development Flexibility**: Developers can have multiple isolated workspaces
-- **System Upgrades**: System updates don't affect user customizations
-- **Multi-User Support**: Multiple users can work independently on same system
-- **Portable Configurations**: User workspace can be moved between systems
-- **State Management**: All user state in predictable locations
-
-### Negative
-
-- **Initial Setup**: Users must initialize workspace before first use
-- **Path Complexity**: More complex path resolution to support workspace isolation
-- **Disk Usage**: Each user maintains separate cache and state
-- **Configuration Duplication**: Some configuration may be duplicated across users
-- **Migration Overhead**: Existing users need workspace migration
-- **Documentation Complexity**: Need clear documentation for workspace management
-
-### Neutral
-
-- **Backup Strategy**: Users responsible for their own workspace backup
-- **Extension Management**: User-specific extension installation and management
-- **Version Compatibility**: Workspace versions must be compatible with system versions
-- **Performance Implications**: Additional path resolution overhead
-
-## Alternatives Considered
-
-### Alternative 1: System-Wide Configuration Only
-
-All configuration in system directories with user overrides via environment variables.
-**Rejected**: Creates conflicts between users and makes customization difficult. Poor isolation and security.
-
-### Alternative 2: Home Directory Dotfiles
-
-Use traditional dotfile approach (~/.provisioning/).
-**Rejected**: Clutters home directory and provides less structured organization. Harder to backup and migrate.
-
-### Alternative 3: XDG Base Directory Specification
-
-Follow XDG specification for config/data/cache separation.
-**Rejected**: While standards-compliant, would fragment user data across multiple directories making management complex.
-
-### Alternative 4: Container-Based Isolation
-
-Each user gets containerized environment.
-**Rejected**: Too heavy for simple configuration isolation. Adds deployment complexity without sufficient benefits.
-
-### Alternative 5: Database-Based Configuration
-
-Store all user configuration in database.
-**Rejected**: Adds dependency complexity and makes backup/restore more difficult. Over-engineering for configuration needs.
-
-## Implementation Details
-
-### Workspace Initialization
-
-```bash
-# Automatic workspace creation on first run
-provisioning workspace init
-
-# Manual workspace creation with template
-provisioning workspace init --template=developer
-
-# Workspace status and validation
-provisioning workspace status
-provisioning workspace validate
-```
-
-### Configuration Resolution Process
-
-1. **Workspace Discovery**: Locate user workspace (env var → default location)
-2. **Configuration Loading**: Load configuration hierarchy with proper precedence
-3. **Path Resolution**: Resolve all paths relative to workspace and system installation
-4. **Variable Interpolation**: Process configuration variables and templates
-5. **Validation**: Validate merged configuration for completeness and correctness
-
-### Backup and Migration
-
-```bash
-# Backup entire workspace
-provisioning workspace backup --output ~/backup/provisioning-workspace.tar.gz
-
-# Restore workspace from backup
-provisioning workspace restore --input ~/backup/provisioning-workspace.tar.gz
-
-# Migrate workspace to new version
-provisioning workspace migrate --from-version 2.0.0 --to-version 3.0.0
-```
-
-### Security Considerations
-
-- **File Permissions**: Workspace created with appropriate user permissions
-- **Secret Management**: Secrets encrypted and isolated within workspace
-- **Extension Sandboxing**: User extensions cannot access system directories
-- **Path Validation**: All paths validated to prevent directory traversal
-- **Configuration Validation**: User configuration validated against schemas

-# ADR-004: Hybrid Architecture
-
-## Status
-
-Accepted
-
-## Context
-
-Provisioning encountered fundamental limitations with a pure Nushell implementation that required architectural solutions:
-
-1. **Deep Call Stack Limitations**: Nushell's `open` command fails in deep call contexts
-   (`enumerate | each`), causing "Type not supported" errors in template.nu:71
-2. **Performance Bottlenecks**: Complex workflow orchestration hitting Nushell's performance limits
-3. **Concurrency Constraints**: Limited parallel processing capabilities in Nushell for batch operations
-4. **Integration Complexity**: Need for REST API endpoints and external system integration
-5. **State Management**: Complex state tracking and persistence requirements beyond Nushell's capabilities
-6. **Business Logic Preservation**: 65+ existing Nushell files with domain expertise that shouldn't be rewritten
-7. **Developer Productivity**: Nushell excels for configuration management and domain-specific operations
-
-The system needed an architecture that:
-
-- Solves Nushell's technical limitations without losing business logic
-- Leverages each language's strengths appropriately
-- Maintains existing investment in Nushell domain knowledge
-- Provides performance for coordination-heavy operations
-- Enables modern integration patterns (REST APIs, async workflows)
-- Preserves configuration-driven, Infrastructure as Code principles
-
-## Decision
-
-Implement a **Hybrid Rust/Nushell Architecture** with clear separation of concerns:
-
-### Architecture Layers
-
-#### 1. Coordination Layer (Rust)
-
-- **Orchestrator**: High-performance workflow coordination and task scheduling
-- **REST API Server**: HTTP endpoints for external integration
-- **State Management**: Persistent state tracking with checkpoint recovery
-- **Batch Processing**: Parallel execution of complex workflows
-- **File-based Persistence**: Lightweight task queue using reliable file storage
-- **Error Recovery**: Sophisticated error handling and rollback capabilities
-
-#### 2. Business Logic Layer (Nushell)
-
-- **Provider Implementations**: Cloud provider-specific operations (AWS, UpCloud, local)
-- **Task Services**: Infrastructure service management (Kubernetes, networking, storage)
-- **Configuration Management**: KCL-based configuration processing and validation
-- **Template Processing**: Infrastructure-as-Code template generation
-- **CLI Interface**: User-facing command-line tools and workflows
-- **Domain Operations**: All business-specific logic and operations
-
-### Integration Patterns
-
-#### Rust → Nushell Communication
-
-```nushell
-// Rust orchestrator invokes Nushell scripts via process execution
-let result = Command::new("nu")
-    .arg("-c")
-    .arg("use core/nulib/workflows/server_create.nu *; server_create_workflow 'name' '' []")
-    .output()?;
-```
-
-#### Nushell → Rust Communication
-
-```nushell
-# Nushell submits workflows to Rust orchestrator via HTTP API
-http post "http://localhost:9090/workflows/servers/create" {
-    name: "server-name",
-    provider: "upcloud",
-    config: $server_config
-}
-```
-
-#### Data Exchange Format
-
-- **Structured JSON**: All data exchange via JSON for type safety and interoperability
-- **Configuration TOML**: Configuration data in TOML format for human readability
-- **State Files**: Lightweight file-based state exchange between layers
-
-### Key Architectural Principles
-
-1. **Language Strengths**: Use each language for what it does best
-2. **Business Logic Preservation**: All existing domain knowledge stays in Nushell
-3. **Performance Critical Path**: Coordination and orchestration in Rust
-4. **Clear Boundaries**: Well-defined interfaces between layers
-5. **Configuration Driven**: Both layers respect configuration-driven architecture
-6. **Error Handling**: Coordinated error handling across language boundaries
-7. **State Consistency**: Consistent state management across hybrid system
-
-## Consequences
-
-### Positive
-
-- **Technical Limitations Solved**: Eliminates Nushell deep call stack issues
-- **Performance Optimized**: High-performance coordination while preserving productivity
-- **Business Logic Preserved**: 65+ Nushell files with domain expertise maintained
-- **Modern Integration**: REST APIs and async workflows enabled
-- **Development Efficiency**: Developers can use optimal language for each task
-- **Batch Processing**: Parallel workflow execution with sophisticated state management
-- **Error Recovery**: Advanced error handling and rollback capabilities
-- **Scalability**: Architecture scales to complex multi-provider workflows
-- **Maintainability**: Clear separation of concerns between layers
-
-### Negative
-
-- **Complexity Increase**: Two-language system requires more architectural coordination
-- **Integration Overhead**: Data serialization/deserialization between languages
-- **Development Skills**: Team needs expertise in both Rust and Nushell
-- **Testing Complexity**: Must test integration between language layers
-- **Deployment Complexity**: Two runtime environments must be coordinated
-- **Debugging Challenges**: Debugging across language boundaries more complex
-
-### Neutral
-
-- **Development Patterns**: Different patterns for each layer while maintaining consistency
-- **Documentation Strategy**: Language-specific documentation with integration guides
-- **Tool Chain**: Multiple development tool chains must be maintained
-- **Performance Characteristics**: Different performance characteristics for different operations
-
-## Alternatives Considered
-
-### Alternative 1: Pure Nushell Implementation
-
-Continue with Nushell-only approach and work around limitations.
-**Rejected**: Technical limitations are fundamental and cannot be worked around without compromising functionality. Deep call stack issues are
-architectural.
-
-### Alternative 2: Complete Rust Rewrite
-
-Rewrite entire system in Rust for consistency.
-**Rejected**: Would lose 65+ files of domain expertise and Nushell's productivity advantages for configuration management. Massive development effort.
-
-### Alternative 3: Pure Go Implementation
-
-Rewrite system in Go for simplicity and performance.
-**Rejected**: Same issues as Rust rewrite - loses domain expertise and Nushell's configuration strengths. Go doesn't provide significant advantages.
-
-### Alternative 4: Python/Shell Hybrid
-
-Use Python for coordination and shell scripts for operations.
-**Rejected**: Loses type safety and configuration-driven advantages of current system. Python adds dependency complexity.
-
-### Alternative 5: Container-Based Separation
-
-Run Nushell and coordination layer in separate containers.
-**Rejected**: Adds deployment complexity and network communication overhead. Complicates local development significantly.
-
-## Implementation Details
-
-### Orchestrator Components
-
-- **Task Queue**: File-based persistent queue for reliable workflow management
-- **HTTP Server**: REST API for workflow submission and monitoring
-- **State Manager**: Checkpoint-based state tracking with recovery
-- **Process Manager**: Nushell script execution with proper isolation
-- **Error Handler**: Comprehensive error recovery and rollback logic
-
-### Integration Protocols
-
-- **HTTP REST**: Primary API for external integration
-- **JSON Data Exchange**: Structured data format for all communication
-- **File-based State**: Lightweight persistence without database dependencies
-- **Process Execution**: Secure subprocess execution for Nushell operations
-
-### Development Workflow
-
-1. **Rust Development**: Focus on coordination, performance, and integration
-2. **Nushell Development**: Focus on business logic, providers, and task services
-3. **Integration Testing**: Validate communication between layers
-4. **End-to-End Validation**: Complete workflow testing across both layers
-
-### Monitoring and Observability
-
-- **Structured Logging**: JSON logs from both Rust and Nushell components
-- **Metrics Collection**: Performance metrics from coordination layer
-- **Health Checks**: System health monitoring across both layers
-- **Workflow Tracking**: Complete audit trail of workflow execution
-
-## Migration Strategy

-# ADR-005: Extension Framework
-
-## Status
-
-Accepted
-
-## Context
-
-Provisioning required a flexible extension mechanism to support:

-8. **Discovery Mechanism**: System must automatically discover and load extensions
-9. **Version Compatibility**: Extensions must work across system version upgrades
-10. **Configuration Integration**: Extensions should integrate with configuration-driven architecture
-
-The system needed an extension framework that provides:
-
-- Clear extension API and interfaces
-- Safe isolation of extension code
-- Automatic discovery and loading
-- Configuration integration
-- Version compatibility management
-- Developer-friendly extension development patterns
-
-## Decision
-
-Implement a **registry-based extension framework** with structured discovery and isolation:

-- **Dependency Management**: Extension dependencies must be managed carefully
-
-## Alternatives Considered
-
-### Alternative 1: Filesystem-Based Extensions
-
-Simple filesystem scanning for extension discovery.
-**Rejected**: No manifest validation or version compatibility checking. Fragile discovery mechanism.
-
-### Alternative 2: Database-Backed Registry
-
-Store extension metadata in database for discovery.
-**Rejected**: Adds database dependency complexity. Over-engineering for extension discovery needs.
-
-### Alternative 3: Package Manager Integration
-
-Use existing package managers (cargo, npm) for extension distribution.
-**Rejected**: Complicates installation and creates external dependencies. Not suitable for corporate environments.
-
-### Alternative 4: Container-Based Extensions
-
-Each extension runs in isolated container.
-**Rejected**: Too heavy for simple extensions. Complicates development and deployment significantly.
-
-### Alternative 5: Plugin Architecture
-
-Traditional plugin architecture with dynamic loading.
-**Rejected**: Complex for shell-based system. Security and isolation challenges in Nushell environment.
-
-## Implementation Details
-
-### Extension Discovery Process
-
-1. **Directory Scanning**: Scan extension directories for manifest files
-2. **Manifest Validation**: Parse and validate extension manifest
-3. **Compatibility Check**: Verify version compatibility requirements
-4. **Dependency Resolution**: Resolve extension dependencies
-5. **Configuration Integration**: Merge extension configuration schemas
-6. **Entry Point Registration**: Register extension entry points with system
-
-### Extension Loading Lifecycle
-
-```bash
-# Extension discovery and validation
-provisioning extension discover
-provisioning extension validate --extension custom-provider
-
-# Extension activation and configuration
-provisioning extension enable custom-provider
-provisioning extension configure custom-provider
-
-# Extension usage
-provisioning provider list  # Shows custom providers
-provisioning server create --provider custom-provider
-
-# Extension management
-provisioning extension disable custom-provider
-provisioning extension update custom-provider
-```
-
-### Configuration Integration
-
-Extensions integrate with hierarchical configuration system:
-
-```toml
-# System configuration includes extension settings
-[custom_provider]
-api_endpoint = "https://api.custom-cloud.com"
-region = "us-west-1"
-timeout = 30
-
-# Extension configuration follows same hierarchy rules
-# System defaults → User config → Environment config → Runtime
-```
-
-### Security and Isolation
-
-- **Sandboxed Execution**: Extensions run in controlled environment
-- **Permission Model**: Extensions declare required permissions in manifest
-- **Code Review**: Community extensions require review process
-- **Digital Signatures**: Extensions can be digitally signed for authenticity
-- **Audit Logging**: Extension usage tracked in system audit logs
-
-### Development Support
-
-- **Extension Templates**: Scaffold new extensions from templates
-- **Development Tools**: Testing and validation tools for extension developers
-- **Documentation Generation**: Automatic documentation from extension manifests
-- **Integration Testing**: Framework for testing extensions with core system
-
-## Extension Development Patterns
-
-### Provider Extension Pattern
-
-```bash
-# extensions/providers/custom-cloud/nulib/provider.nu
-export def list-servers [] -> table {
-    http get $"($config.custom_provider.api_endpoint)/servers"
-    | from json
-    | select name status region
-}
-
-export def create-server [name: string, config: record] -> record {
-    let payload = {
-        name: $name,
-        instance_type: $config.plan,
-        region: $config.zone
-    }
-
-    http post $"($config.custom_provider.api_endpoint)/servers" $payload
-    | from json
-}
-```
-
-### Task Service Extension Pattern
-
-```bash
-# extensions/taskservs/custom-service/nulib/service.nu
-export def install [server: string] -> nothing {
-    let manifest_data = open ./manifests/deployment.yaml
-    | str replace "{{server}}" $server
-
-    kubectl apply --server $server --data $manifest_data
-}
-
-export def uninstall [server: string] -> nothing {
-    kubectl delete deployment custom-service --server $server
-}
-```

-# ADR-006: Provisioning CLI Refactoring to Modular Architecture
-
-**Status**: Implemented ✅
-**Date**: 2025-09-30
-**Authors**: Infrastructure Team
-**Related**: ADR-001 (Project Structure), ADR-004 (Hybrid Architecture)
-
-## Context
-
-The main provisioning CLI script (`provisioning/core/nulib/provisioning`) had grown to
-**1,329 lines** with a massive 1,100+ line match statement handling all commands. This
-monolithic structure created multiple critical problems:
-
-### Problems Identified
-
-1. **Maintainability Crisis**
-   - 54 command branches in one file
-   - Code duplication: Flag handling repeated 50+ times
-   - Hard to navigate: Finding specific command logic required scrolling through 1,000+ lines
-   - Mixed concerns: Routing, validation, and execution all intertwined
-
-2. **Development Friction**
-   - Adding new commands required editing massive file
-   - Testing was nearly impossible (monolithic, no isolation)
-   - High cognitive load for contributors
-   - Code review difficult due to file size
-
-3. **Technical Debt**
-   - 10+ lines of repetitive flag handling per command
-   - No separation of concerns
-   - Poor code reusability
-   - Difficult to test individual command handlers
-
-4. **User Experience Issues**
-   - No bi-directional help system
-   - Inconsistent command shortcuts
-   - Help system not fully integrated
-
-## Decision
-
-We refactored the monolithic CLI into a **modular, domain-driven architecture** with the following structure:
-
-```bash
-provisioning/core/nulib/
-├── provisioning (211 lines) ⬅️ 84% reduction
-├── main_provisioning/
-│   ├── flags.nu (139 lines) ⭐ Centralized flag handling
-│   ├── dispatcher.nu (264 lines) ⭐ Command routing
-│   ├── mod.nu (updated)
-│   └── commands/ ⭐ Domain-focused handlers
-│       ├── configuration.nu (316 lines)
-│       ├── development.nu (72 lines)
-│       ├── generation.nu (78 lines)
-│       ├── infrastructure.nu (117 lines)
-│       ├── orchestration.nu (64 lines)
-│       ├── utilities.nu (157 lines)
-│       └── workspace.nu (56 lines)
-```
-
-### Key Components
-
-#### 1. Centralized Flag Handling (`flags.nu`)
-
-Single source of truth for all flag parsing and argument building:
-
-```javascript
-export def parse_common_flags [flags: record]: nothing -> record
-export def build_module_args [flags: record, extra: string = ""]: nothing -> string
-export def set_debug_env [flags: record]
-export def get_debug_flag [flags: record]: nothing -> string
-```
-
-**Benefits:**
-
-- Eliminates 50+ instances of duplicate code
-- Single place to add/modify flags
-- Consistent flag handling across all commands
-- Reduced from 10 lines to 3 lines per command handler
-
-#### 2. Command Dispatcher (`dispatcher.nu`)
-
-Central routing with 80+ command mappings:
-
-```javascript
-export def get_command_registry []: nothing -> record  # 80+ shortcuts
-export def dispatch_command [args: list, flags: record]  # Main router
-```
-
-**Features:**
-
-- Command registry with shortcuts (ws → workspace, orch → orchestrator, etc.)
-- Bi-directional help support (`provisioning ws help` works)
-- Domain-based routing (infrastructure, orchestration, development, etc.)
-- Special command handling (create, delete, price, etc.)
-
-#### 3. Domain Command Handlers (`commands/*.nu`)
-
-Seven focused modules organized by domain:
-
-| Module | Lines | Responsibility |
-| -------- | ------- | ---------------- |
-| `infrastructure.nu` | 117 | Server, taskserv, cluster, infra |
-| `orchestration.nu` | 64 | Workflow, batch, orchestrator |
-| `development.nu` | 72 | Module, layer, version, pack |
-| `workspace.nu` | 56 | Workspace, template |
-| `generation.nu` | 78 | Generate commands |
-| `utilities.nu` | 157 | SSH, SOPS, cache, providers |
-| `configuration.nu` | 316 | Env, show, init, validate |
-
-Each handler:
-
-- Exports `handle_<domain>_command` function
-- Uses shared flag handling
-- Provides error messages with usage hints
-- Isolated and testable
-
-## Architecture Principles
-
-### 1. Separation of Concerns
-
-- **Routing** → `dispatcher.nu`
-- **Flag parsing** → `flags.nu`
-- **Business logic** → `commands/*.nu`
-- **Help system** → `help_system.nu` (existing)
-
-### 2. Single Responsibility
-
-Each module has ONE clear purpose:
-
-- Command handlers execute specific domains
-- Dispatcher routes to correct handler
-- Flags module normalizes all inputs
-
-### 3. DRY (Don't Repeat Yourself)
-
-Eliminated repetition:
-
-- Flag handling: 50+ instances → 1 function
-- Command routing: Scattered logic → Command registry
-- Error handling: Consistent across all domains
-
-### 4. Open/Closed Principle
-
-- Open for extension: Add new handlers easily
-- Closed for modification: Core routing unchanged
-
-### 5. Dependency Inversion
-
-All handlers depend on abstractions (flag records, not concrete flags):
-
-```bash
-# Handler signature
-export def handle_infrastructure_command [
-  command: string
-  ops: string
-  flags: record  # ⬅️ Abstraction, not concrete flags
-]
-```
-
-## Implementation Details
-
-### Migration Path (Completed in 2 Phases)
-
-**Phase 1: Foundation**
-
-1. ✅ Created `commands/` directory structure
-2. ✅ Created `flags.nu` with common flag handling
-3. ✅ Created initial command handlers (infrastructure, utilities, configuration)
-4. ✅ Created `dispatcher.nu` with routing logic
-5. ✅ Refactored main file (1,329 → 211 lines)
-6. ✅ Tested basic functionality
-
-**Phase 2: Completion**
-
-1. ✅ Fixed bi-directional help (`provisioning ws help` now works)
-2. ✅ Created remaining handlers (orchestration, development, workspace, generation)
-3. ✅ Removed duplicate code from dispatcher
-4. ✅ Added comprehensive test suite
-5. ✅ Verified all shortcuts work
-
-### Bi-directional Help System
-
-Users can now access help in multiple ways:
-
-```bash
-# All these work equivalently:
-provisioning help workspace
-provisioning workspace help  # ⬅️ NEW: Bi-directional
-provisioning ws help         # ⬅️ NEW: With shortcuts
-provisioning help ws         # ⬅️ NEW: Shortcut in help
-```
-
-**Implementation:**
-
-```bash
-# Intercept "command help" → "help command"
-let first_op = if ($ops_list | length) > 0 { ($ops_list | get 0) } else { "" }
-if $first_op in ["help" "h"] {
-  exec $"($env.PROVISIONING_NAME)" help $task --notitles
-}
-```
-
-### Command Shortcuts
-
-Comprehensive shortcut system with 30+ mappings:
-
-**Infrastructure:**
-
-- `s` → `server`
-- `t`, `task` → `taskserv`
-- `cl` → `cluster`
-- `i` → `infra`
-
-**Orchestration:**
-
-- `wf`, `flow` → `workflow`
-- `bat` → `batch`
-- `orch` → `orchestrator`
-
-**Development:**
-
-- `mod` → `module`
-- `lyr` → `layer`
-
-**Workspace:**
-
-- `ws` → `workspace`
-- `tpl`, `tmpl` → `template`
-

-
-## Examples
-
-### Before: Repetitive Flag Handling
-
-```bash
-"server" => {
-  let use_check = if $check { "--check "} else { "" }
-  let use_yes = if $yes { "--yes" } else { "" }
-  let use_wait = if $wait { "--wait" } else { "" }
-  let use_keepstorage = if $keepstorage { "--keepstorage "} else { "" }
-  let str_infra = if $infra != null  { $"--infra ($infra) "} else { "" }
-  let str_outfile = if $outfile != null  { $"--outfile ($outfile) "} else { "" }
-  let str_out = if $out != null  { $"--out ($out) "} else { "" }
-  let arg_include_notuse = if $include_notuse { $"--include_notuse "} else { "" }
-  run_module $"($str_ops) ($str_infra) ($use_check)..." "server" --exec
-}
-```
-
-### After: Clean, Reusable
-
-```python
-def handle_server [ops: string, flags: record] {
-  let args = build_module_args $flags $ops
-  run_module $args "server" --exec
-}
-```
-
-**Reduction: 10 lines → 3 lines (70% reduction)**
-
-## Future Considerations

-# ADR-007: KMS Service Simplification to Age and Cosmian Backends
-
-**Status**: Accepted
-**Date**: 2025-10-08
-**Deciders**: Architecture Team
-**Related**: ADR-006 (KMS Service Integration)
-
-## Context
-
-The KMS service initially supported 4 backends: HashiCorp Vault, AWS KMS, Age, and Cosmian KMS. This created unnecessary complexity and unclear
-guidance about which backend to use for different environments.
-
-### Problems with 4-Backend Approach
-
-1. **Complexity**: Supporting 4 different backends increased maintenance burden
-2. **Dependencies**: AWS SDK added significant compile time (~30 s) and binary size
-3. **Confusion**: No clear guidance on which backend to use when
-4. **Cloud Lock-in**: AWS KMS dependency limited infrastructure flexibility
-5. **Operational Overhead**: Vault requires server setup even for simple dev environments
-6. **Code Duplication**: Similar logic implemented 4 different ways
-
-### Key Insights
-
-- Most development work doesn't need server-based KMS
-- Production deployments need enterprise-grade security features
-- Age provides fast, offline encryption perfect for development
-- Cosmian KMS offers confidential computing and zero-knowledge architecture
-- Supporting Vault AND Cosmian is redundant (both are server-based KMS)
-- AWS KMS locks us into AWS infrastructure
-
-## Decision
-
-Simplify the KMS service to support only 2 backends:
-
-1. **Age**: For development and local testing
-   - Fast, offline, no server required
-   - Simple key generation with `age-keygen`
-   - X25519 encryption (modern, secure)
-   - Perfect for dev/test environments
-
-2. **Cosmian KMS**: For production deployments
-   - Enterprise-grade key management
-   - Confidential computing support (SGX/SEV)
-   - Zero-knowledge architecture
-   - Server-side key rotation
-   - Audit logging and compliance
-   - Multi-tenant support
-
-Remove support for:
-
-- ❌ HashiCorp Vault (redundant with Cosmian)
-- ❌ AWS KMS (cloud lock-in, complexity)
-
-## Consequences
-
-### Positive
-
-1. **Simpler Code**: 2 backends instead of 4 reduces complexity by 50%
-2. **Faster Compilation**: Removing AWS SDK saves ~30 seconds compile time
-3. **Clear Guidance**: Age = dev, Cosmian = prod (no confusion)
-4. **Offline Development**: Age works without network connectivity
-5. **Better Security**: Cosmian provides confidential computing (TEE)
-6. **No Cloud Lock-in**: Not dependent on AWS infrastructure
-7. **Easier Testing**: Age backend requires no setup
-8. **Reduced Dependencies**: Fewer external crates to maintain
-
-### Negative
-
-1. **Migration Required**: Existing Vault/AWS KMS users must migrate
-2. **Learning Curve**: Teams must learn Age and Cosmian
-3. **Cosmian Dependency**: Production depends on Cosmian availability
-4. **Cost**: Cosmian may have licensing costs (cloud or self-hosted)
-
-### Neutral
-
-1. **Feature Parity**: Cosmian provides all features Vault/AWS had
-2. **API Compatibility**: Encrypt/decrypt API remains primarily the same
-3. **Configuration Change**: TOML config structure updated but similar
-
-## Implementation
-
-### Files Created
-
-1. `src/age/client.rs` (167 lines) - Age encryption client
-2. `src/age/mod.rs` (3 lines) - Age module exports
-3. `src/cosmian/client.rs` (294 lines) - Cosmian KMS client
-4. `src/cosmian/mod.rs` (3 lines) - Cosmian module exports
-5. `docs/migration/KMS_SIMPLIFICATION.md` (500+ lines) - Migration guide
-
-### Files Modified
-
-1. `src/lib.rs` - Updated exports (age, cosmian instead of aws, vault)
-2. `src/types.rs` - Updated error types and config enum
-3. `src/service.rs` - Simplified to 2 backends (180 lines, was 213)
-4. `Cargo.toml` - Removed AWS deps, added `age = "0.10"`
-5. `README.md` - Complete rewrite for new backends
-6. `provisioning/config/kms.toml` - Simplified configuration
-
-### Files Deleted
-
-1. `src/aws/client.rs` - AWS KMS client
-2. `src/aws/envelope.rs` - Envelope encryption helpers
-3. `src/aws/mod.rs` - AWS module
-4. `src/vault/client.rs` - Vault client
-5. `src/vault/mod.rs` - Vault module
-
-### Dependencies Changed
-
-**Removed**:
-
-- `aws-sdk-kms = "1"`
-- `aws-config = "1"`
-- `aws-credential-types = "1"`
-- `aes-gcm = "0.10"` (was only for AWS envelope encryption)
-
-**Added**:
-
-- `age = "0.10"`
-- `tempfile = "3"` (dev dependency for tests)
-
-**Kept**:
-
-- All Axum web framework deps
-- `reqwest` (for Cosmian HTTP API)
-- `base64`, `serde`, `tokio`, etc.
-
-## Migration Path
-
-### For Development
-
-```bash
-# 1. Install Age
-brew install age  # or apt install age
-
-# 2. Generate keys
-age-keygen -o ~/.config/provisioning/age/private_key.txt
-age-keygen -y ~/.config/provisioning/age/private_key.txt > ~/.config/provisioning/age/public_key.txt
-
-# 3. Update config to use Age backend
-# 4. Re-encrypt development secrets
-```
-
-### For Production
-
-```bash
-# 1. Set up Cosmian KMS (cloud or self-hosted)
-# 2. Create master key in Cosmian
-# 3. Migrate secrets from Vault/AWS to Cosmian
-# 4. Update production config
-# 5. Deploy new KMS service
-```
-
-See `docs/migration/KMS_SIMPLIFICATION.md` for detailed steps.
-

-# ADR-008: Cedar Authorization Policy Engine Integration
-
-**Status**: Accepted
-**Date**: 2025-10-08
-**Deciders**: Architecture Team
-**Tags**: security, authorization, cedar, policy-engine
-
-## Context and Problem Statement
-
-The Provisioning platform requires fine-grained authorization controls to manage access to infrastructure resources across multiple environments
-(development, staging, production). The authorization system must:
-
-1. Support complex authorization rules (MFA, IP restrictions, time windows, approvals)
-2. Be auditable and version-controlled
-3. Allow hot-reload of policies without restart
-4. Integrate with JWT tokens for identity
-5. Scale to thousands of authorization decisions per second
-6. Be maintainable by security team without code changes
-
-Traditional code-based authorization (if/else statements) is difficult to audit, maintain, and scale.
-
-## Decision Drivers
-
-- **Security**: Critical for production infrastructure access
-- **Auditability**: Compliance requirements demand clear authorization policies
-- **Flexibility**: Policies change more frequently than code
-- **Performance**: Low-latency authorization decisions (<10 ms)
-- **Maintainability**: Security team should update policies without developers
-- **Type Safety**: Prevent policy errors before deployment
-
-## Considered Options
-
-### Option 1: Code-Based Authorization (Current State)
-
-Implement authorization logic directly in Rust/Nushell code.
-
-**Pros**:
-
-- Full control and flexibility
-- No external dependencies
-- Simple to understand for small use cases
-
-**Cons**:
-
-- Hard to audit and maintain
-- Requires code deployment for policy changes
-- No type safety for policies
-- Difficult to test all combinations
-- Not declarative
-
-### Option 2: OPA (Open Policy Agent)
-
-Use OPA with Rego policy language.
-
-**Pros**:
-
-- Industry standard
-- Rich ecosystem
-- Rego is powerful
-
-**Cons**:
-
-- Rego is complex to learn
-- Requires separate service deployment
-- Performance overhead (HTTP calls)
-- Policies not type-checked
-
-### Option 3: Cedar Policy Engine (Chosen)
-
-Use AWS Cedar policy language integrated directly into orchestrator.
-
-**Pros**:
-
-- Type-safe policy language
-- Fast (compiled, no network overhead)
-- Schema-based validation
-- Declarative and auditable
-- Hot-reload support
-- Rust library (no external service)
-- Deny-by-default security model
-
-**Cons**:
-
-- Recently introduced (2023)
-- Smaller ecosystem than OPA
-- Learning curve for policy authors
-
-### Option 4: Casbin
-
-Use Casbin authorization library.
-
-**Pros**:
-
-- Multiple policy models (ACL, RBAC, ABAC)
-- Rust bindings available
-
-**Cons**:
-
-- Less declarative than Cedar
-- Weaker type safety
-- More imperative style
-
-## Decision Outcome
-
-**Chosen Option**: Option 3 - Cedar Policy Engine
-
-### Rationale
-
-1. **Type Safety**: Cedar's schema validation prevents policy errors before deployment
-2. **Performance**: Native Rust library, no network overhead, <1 ms authorization decisions
-3. **Auditability**: Declarative policies in version control
-4. **Hot Reload**: Update policies without orchestrator restart
-5. **AWS Standard**: Used in production by AWS for AVP (Amazon Verified Permissions)
-6. **Deny-by-Default**: Secure by design

-#### Policy Organization
-
-```bash
-provisioning/config/cedar-policies/
-├── schema.cedar          # Entity and action definitions
-├── production.cedar      # Production environment policies
-├── development.cedar     # Development environment policies
-├── admin.cedar          # Administrative policies
-└── README.md            # Documentation
-```
-
-#### Rust Implementation
-
-```rust
-provisioning/platform/orchestrator/src/security/
-├── cedar.rs             # Cedar engine integration (450 lines)
-├── policy_loader.rs     # Policy loading with hot reload (320 lines)

-├── mod.rs              # Module exports
-└── tests.rs            # Comprehensive tests (450 lines)
-```
-
-#### Key Components
-
-1. **CedarEngine**: Core authorization engine
-   - Load policies from strings
-   - Load schema for validation
-   - Authorize requests
-   - Policy statistics
-
-2. **PolicyLoader**: File-based policy management
-   - Load policies from directory
-   - Hot reload on file changes (notify crate)
-   - Validate policy syntax
-   - Schema validation
-
-3. **Authorization Middleware**: Axum integration
-   - Extract JWT claims
-   - Build authorization context (IP, MFA, time)
-   - Check authorization
-   - Return 403 Forbidden on deny
-
-4. **Policy Files**: Declarative authorization rules
-   - Production: MFA, approvals, IP restrictions, business hours
-   - Development: Permissive for developers
-   - Admin: Platform admin, SRE, audit team policies
-
-#### Context Variables
-
-```bash
-AuthorizationContext {
-    mfa_verified: bool,          // MFA verification status
-    ip_address: String,          // Client IP address
-    time: String,                // ISO 8601 timestamp
-    approval_id: Option<String>, // Approval ID (optional)
-    reason: Option<String>,      // Reason for operation
-    force: bool,                 // Force flag
-    additional: HashMap,         // Additional context
-}
-```
-
-#### Example Policy
-
-```bash
-// Production deployments require MFA verification
-@id("prod-deploy-mfa")
-@description("All production deployments must have MFA verification")
-permit (
-  principal,
-  action == Provisioning::Action::"deploy",
-  resource in Provisioning::Environment::"production"
-) when {
-  context.mfa_verified == true
-};
-```
-
-### Integration Points
-
-1. **JWT Tokens**: Extract principal and context from validated JWT
-2. **Audit System**: Log all authorization decisions
-3. **Control Center**: UI for policy management and testing
-4. **CLI**: Policy validation and testing commands
-
-### Security Best Practices
-
-1. **Deny by Default**: Cedar defaults to deny all actions
-2. **Schema Validation**: Type-check policies before loading
-3. **Version Control**: All policies in git for auditability
-4. **Principle of Least Privilege**: Grant minimum necessary permissions
-5. **Defense in Depth**: Combine with JWT validation and rate limiting
-6. **Separation of Concerns**: Security team owns policies, developers own code
-
-## Consequences
-
-### Positive
-
-1. ✅ **Auditable**: All policies in version control
-2. ✅ **Type-Safe**: Schema validation prevents errors
-3. ✅ **Fast**: <1 ms authorization decisions
-4. ✅ **Maintainable**: Security team can update policies independently
-5. ✅ **Hot Reload**: No downtime for policy updates
-6. ✅ **Testable**: Comprehensive test suite for policies
-7. ✅ **Declarative**: Clear intent, no hidden logic
-
-### Negative
-
-1. ❌ **Learning Curve**: Team must learn Cedar policy language
-2. ❌ **New Technology**: Cedar is relatively new (2023)
-3. ❌ **Ecosystem**: Smaller community than OPA
-4. ❌ **Tooling**: Limited IDE support compared to Rego
-
-### Neutral
-
-1. 🔶 **Migration**: Existing authorization logic needs migration to Cedar
-2. 🔶 **Policy Complexity**: Complex rules may be harder to express
-3. 🔶 **Debugging**: Policy debugging requires understanding Cedar evaluation
-
-## Compliance
-
-### Security Standards
-
-- **SOC 2**: Auditable access control policies
-- **ISO 27001**: Access control management
-- **GDPR**: Data access authorization and logging
-- **NIST 800-53**: AC-3 Access Enforcement
-
-### Audit Requirements
-
-All authorization decisions include:
-
-- Principal (user/team)
-- Action performed
-- Resource accessed
-- Context (MFA, IP, time)
-- Decision (allow/deny)
-- Policies evaluated
-
-## Migration Path
-
-### Phase 1: Implementation (Completed)
-
-- ✅ Cedar engine integration
-- ✅ Policy loader with hot reload
-- ✅ Authorization middleware
-- ✅ Production, development, and admin policies
-- ✅ Comprehensive tests
-
-### Phase 2: Rollout (Next)
-
-- 🔲 Enable Cedar authorization in orchestrator
-- 🔲 Migrate existing authorization logic to Cedar policies
-- 🔲 Add authorization checks to all API endpoints
-- 🔲 Integrate with audit logging
-
-### Phase 3: Enhancement (Future)
-
-- 🔲 Control Center policy editor UI
-- 🔲 Policy testing UI
-- 🔲 Policy simulation and dry-run mode
-- 🔲 Policy analytics and insights
-- 🔲 Advanced context variables (location, device type)
-
-## Alternatives Considered
-
-### Alternative 1: Continue with Code-Based Authorization
-
-Keep authorization logic in Rust/Nushell code.
-
-**Rejected Because**:
-
-- Not auditable
-- Requires code changes for policy updates
-- Difficult to test all combinations
-- Not compliant with security standards
-
-### Alternative 2: Hybrid Approach
-
-Use Cedar for high-level policies, code for fine-grained checks.
-
-**Rejected Because**:
-
-- Complexity of two authorization systems
-- Unclear separation of concerns
-- Harder to audit

+# ADR-001: Modular CLI Architecture
+
+**Decision**: Implement modular CLI architecture for 80% code reduction.
+
+## Context
+
+The provisioning CLI needed to support 111+ commands across multiple domains
+(compute, networking, storage, databases, monitoring) while maintaining
+code clarity and reducing maintenance burden.
+
+## Decision
+
+Implement a command module system where:
+
+1. Each domain (compute, network, etc.) defines commands in isolation
+2. Commands auto-register with core CLI
+3. Shortcuts reduce 80% of command length
+4. Type-safe argument handling via Nickel schemas
+
+## Implementation
+
+Commands structured as:
+
+```text
+provisioning/core/commands/
+├── compute/
+│   ├── create-server.nu
+│   ├── delete-server.nu
+│   └── list-servers.nu
+├── network/
+│   ├── create-vpc.nu
+│   └── manage-firewall.nu
+└── database/
+    ├── create-db.nu
+    └── backup-db.nu
+```
+
+## Benefits
+
+- **Code Reuse**: 80% reduction in duplicated code
+- **Maintainability**: Each command self-contained
+- **Extensibility**: New domains plug in easily
+- **Performance**: Shortcuts reduce typing
+
+## Tradeoffs
+
+- Slightly more indirection in command dispatch
+- Learning curve for extension developers
+

+# ADR-002: Workspace-First Architecture
+
+**Decision**: Make workspaces the primary organizational unit for infrastructure.
+
+## Context
+
+Provisioning users manage infrastructure across multiple environments
+(dev, staging, prod), providers (AWS, UpCloud, Hetzner), and projects.
+Previous flat structure lacked organization.
+
+## Decision
+
+Workspaces become first-class entities containing:
+- Infrastructure definitions (Nickel configs)
+- Runtime state and history
+- Secrets and credentials (vault)
+- Custom schemas and extensions
+- Deployment history and rollback points
+
+## Structure
+
+```text
+workspace/
+├── config/          # Nickel configurations
+├── infra/           # Infrastructure definitions
+├── schemas/         # Custom schemas

+├── .workspace/      # Metadata
+├── state.json       # Current state
+└── history/         # Deployment history
+```
+
+## Benefits
+
+- **Isolation**: Complete separation between environments
+- **Collaboration**: Team-based workspace permissions
+- **Versioning**: Full deployment history per workspace
+- **Flexibility**: Each workspace customizable
+
+## Implementation

+# ADR-003: Nickel as Source of Truth
+
+**Status**: Accepted | **Date**: 2025-01-16 | **Supersedes**: None
+
+## Context
+
+The Provisioning platform must support infrastructure-as-code with type-safe configuration
+management. Historical alternatives included KCL and TOML-based configurations.
+
+## Decision
+
+Nickel is adopted as the **exclusive source of truth** for all infrastructure configurations
+across all environments (developer, production, CI/CD). Type safety is mandatory, not optional.
+
+## Rationale
+
+1. **Type Safety**: Nickel provides compile-time type checking preventing configuration errors before deployment
+2. **Expressiveness**: Function composition and lazy evaluation support complex infrastructure patterns
+3. **Validation**: Integration with Cedar policies ensures security at configuration level
+4. **Hierarchy Support**: Seamless merging of configuration layers (core → workspace → profile → environment → runtime)
+5. **Tooling**: First-class IDE support (VSCode plugins) and CLI integration
+
+## Consequences
+
+- **Positive**:
+  - Zero configuration type errors in production
+  - IDE type hints during configuration writing
+  - Automatic schema validation
+  - Reduced debugging time (validation catches errors early)
+  - 100% configuration reproducibility
+
+- **Negative**:
+  - Learning curve for developers unfamiliar with functional programming
+  - TOML migration required for existing projects
+  - Nushell plugin performance impact for large configs (mitigated by caching)
+
+## Implementation
+
+### Configuration Hierarchy
+
+```nickel
+# Layer 1: Core defaults (provisioning/schemas/main.ncl)
+let defaults = {
+  infrastructure.compute.region = "us-east-1",
+  infrastructure.compute.auto_scaling = { enabled = false }
+}
+
+# Layer 2: Workspace schema (workspace/schema.ncl)
+let workspace_config = {
+  infrastructure.compute.region = "us-west-2",  # Override defaults
+}
+
+# Layer 3: Profile config (workspace/profiles/production.ncl)
+let profile_config = {
+  infrastructure.compute.auto_scaling.enabled = true,  # Override workspace
+}
+
+# Layer 4: Environment config (workspace/env/prod.env.ncl)
+let env_config = {
+  infrastructure.compute.instance_count = 5,  # Environment-specific
+}
+
+# Final merged config
+defaults | merge workspace_config | merge profile_config | merge env_config
+```
+
+### Type Validation
+
+All configurations must pass type validation:
+
+```nickel
+# provisioning/schemas/main.ncl
+{
+  infrastructure = {
+    compute | type = {
+      region | type = String,
+      instance_type | type = String,
+      count | type = Number & (> 0),
+      auto_scaling | type = {
+        enabled | type = Bool,
+        min | type = Number & (> 0),
+        max | type = Number & (>= min),
+      }
+    }
+  }
+}
+```
+
+### Validation Command
+
+```bash
+provisioning validate config --profile production --environment prod
+# Returns: Type errors, policy violations, or success confirmation
+```
+
+## Related ADRs
+
+- [ADR-001: Modular CLI Architecture](./adr-001-modular-cli.md) - CLI supports Nickel validation
+- [ADR-002: Workspace-First Design](./adr-002-workspace-first.md) - Workspaces organize Nickel configs
+- [ADR-011: Nickel Migration](./adr-011-nickel-migration.md) - KCL → Nickel transition
+
+## Alternatives Considered
+
+1. **TOML** - Rejected: No type safety, parsing errors cascade to runtime
+2. **KCL** - Rejected: Superceded by Nickel, full migration complete
+3. **Hybrid TOML+Validation** - Rejected: Configuration is truth, validation is secondary (violates IaC principle)

+# ADR-004: 12-Microservice Architecture for Platform Services
+
+**Status**: Accepted | **Date**: 2025-01-16 | **Supersedes**: None
+
+## Context
+
+Provisioning platform requires distributed architecture to handle multi-cloud orchestration, security, extensibility, and scalability independently.
+
+## Decision
+
+The platform consists of 12 distinct Rust microservices, each with a single responsibility and independent deployment lifecycle.
+
+## Rationale
+
+**Scalability**: Each service scales independently based on load (orchestrator handles workflows, vault-service handles secrets)
+
+**Resilience**: Service failure doesn't cascade (e.g., vault-service unavailability doesn't block orchestrator operation)
+
+**Development**: Teams work on services independently without coordination on core logic
+
+**Deployment**: Services update independently, enabling rapid iteration and rollback
+
+## Architecture
+
+### Core Services (5)
+
+1. **Orchestrator** - Workflow execution, DAG scheduling, task coordination
+   - Persistence: File-based (SurrealDB optional for clustering)
+   - Responsibility: Batch workflows, blue-green deployments, rollback
+
+2. **Control-Center** - Workspace management, configuration, settings
+   - Persistence: SurrealDB (relationships)
+   - Responsibility: Workspace CRUD, infrastructure state, user settings
+
+3. **Control-Center-UI** - Web UI for infrastructure management
+   - Framework: Rust Actix-web + frontend (WASM/React)
+   - Responsibility: Dashboard, infrastructure visualization, settings UI
+
+4. **Vault-Service** - Secrets management, encryption, key rotation
+   - Integration: SecretumVault (post-quantum cryptography)
+   - Responsibility: Secret CRUD, encryption at-rest, audit logging
+
+5. **KMS (Key Management Service)** - Cryptographic key operations
+   - Algorithms: AES-256, RSA-4096, CRYSTALS-Kyber, Falcon, SPHINCS+
+   - Responsibility: Key generation, rotation, derivation, policy enforcement
+
+### Support Services (4)
+
+6. **Extension-Registry** - Marketplace for providers and plugins
+   - Responsibility: Version management, discovery, installation, update checks
+
+7. **AI-Service** - Infrastructure intelligence via LLMs and RAG
+   - Backends: OpenAI, Anthropic, Ollama (local)
+   - Responsibility: NLI processing, policy generation, infrastructure recommendations
+
+8. **Detector** - Automatic infrastructure analysis and cost optimization
+   - Responsibility: Resource rightsizing, cost anomalies, compliance violations
+
+9. **RAG (Retrieval-Augmented Generation)** - Knowledge base and semantic search
+   - Storage: SurrealDB vector embeddings (HNSW)
+   - Responsibility: Document indexing, semantic search, relevance ranking
+
+### Internal Services (3)
+
+10. **MCP-Server (Model Context Protocol)** - LLM integration layer
+    - Responsibility: Tool discovery, protocol translation, context management
+
+11. **Platform-Config** - Distributed configuration management
+    - Responsibility: Config distribution, secrets injection, environment-specific overrides
+
+12. **Provisioning-Daemon** - Agent for on-premise/hybrid deployments
+    - Responsibility: Local execution, reporting, health checks
+
+### Service Communication
+
+```text
+CLI → Control-Center (workspace API)
+   → Orchestrator (workflow execution)
+   → Vault-Service (secrets)
+   → Extension-Registry (plugin lookup)
+   → AI-Service (intelligence)
+
+Control-Center → SurrealDB (state)
+              → MCP-Server (LLM tools)
+              → RAG (knowledge)
+
+Orchestrator → Provisioning-Daemon (execution)
+            → Detector (analysis)
+```
+
+## Deployment Model
+
+**Standard**: All 12 services deployed together
+**Lightweight**: Core 5 services only (minimal footprint)
+**Distributed**: Services split across availability zones
+**On-Premise**: Orchestrator + Vault-Service + Daemon (no cloud dependencies)
+
+## Consequences
+
+- **Positive**:
+  - Independent scaling and updates
+  - Clear ownership (each service has team)
+  - Parallel development (services don't block each other)
+  - Technology choices per service (not all must be Rust)
+  - Easy testing (mock services for unit tests)
+
+- **Negative**:
+  - Operational complexity (12 services to monitor)
+  - Network latency between services
+  - Distributed debugging challenges
+  - Data consistency across services
+  - Deployment coordination overhead
+
+## Mitigation
+
+1. **Monitoring**: Unified observability stack (Prometheus + Jaeger)
+2. **Communication**: Synchronous REST (latency < 100ms), async queues for high-latency ops
+3. **State Management**: SurrealDB as source of truth, services maintain caches
+4. **Resilience**: Circuit breakers, timeouts, fallbacks, retries with exponential backoff
+5. **Testing**: Integration test suite covering all service interactions

+# ADR-005: Service Communication Protocol (REST + Async Queue)
+
+**Status**: Accepted | **Date**: 2025-01-16 | **Supersedes**: None
+
+## Context
+
+With 12 microservices, a communication strategy is required balancing reliability, latency, and complexity.
+
+## Decision
+
+Dual communication model:
+- **Synchronous**: REST API for request-response (latency < 100ms target)
+- **Asynchronous**: Message queues for long-running operations (batch workflows, resource provisioning)
+
+## Rationale
+
+1. **REST for Immediate Operations**:
+   - Control flow requires immediate feedback (CLI commands, UI actions)
+   - Latency critical for user experience
+   - Error handling simpler with synchronous responses
+
+2. **Queues for Long Operations**:
+   - Workflow execution may take hours
+   - Network failures shouldn't cancel operations
+   - Load smoothing across services
+   - Better resource utilization
+
+## Implementation
+
+### REST Endpoints
+
+All services expose Actix-web REST APIs:
+
+```rust
+// /provisioning/platform/crates/*/src/api/
+pub struct ApiServer {
+    router: Router,
+}
+
+impl ApiServer {
+    pub fn new() -> Self {
+        Router::new()
+            .route("/health", get(health_check))
+            .route("/api/v1/resources", get(list_resources))
+            .route("/api/v1/resources/:id", get(get_resource))
+            .route("/api/v1/resources", post(create_resource))
+    }
+}
+```
+
+### Async Queue Pattern
+
+Using Nushell for queue management and Rust services as workers:
+
+```bash
+# Submit workflow to queue
+provisioning batch submit workflows/multi-cloud-deploy.ncl \
+  --queue async \
+  --callback https://control-center/webhooks/workflow-complete
+
+# Queue persists to file-based storage
+# Worker (orchestrator) processes asynchronously
+# Client polls status or receives webhook notification
+```
+
+### Error Handling
+
+**REST failures**:
+```rust
+match client.get("/vault-service/health").await {
+    Ok(response) => { /* continue */ },
+    Err(_) => {
+        // Fallback: Use cached secrets
+        // Retry with exponential backoff
+        // Alert monitoring
+    }
+}
+```
+
+**Queue failures**:
+```nushell
+# Failed messages retry with backoff
+orchestrator submit --queue async --max-retries 3 --backoff exponential
+# After retries exhausted, move to dead-letter queue for manual review
+```
+
+## Request Flow
+
+### Synchronous (REST)
+
+```text
+CLI → Control-Center API (100ms)
+  → Workspace lookup ✓
+  → Return workspace config ✓
+Response to user
+```
+
+### Asynchronous (Queue)
+
+```text
+CLI → Orchestrator (accept immediately)
+  → Queue workflow (100ms)
+  ✓ Return job_id to user
+
+[Async worker]
+Orchestrator processes job
+  → Execute tasks
+  → Update SurrealDB state
+  → Send webhook notification
+User polls status or receives notification
+```
+
+## Latency Targets
+
+| Operation | Target | SLA |
+| ----------- | -------- | ----- |
+| Health check | <50ms | 99.95% |
+| List workspaces | <200ms | 99.9% |
+| Create workspace | <500ms | 99.5% |
+| Start workflow | <1s | 99% |
+| Task execution | minutes/hours | N/A (monitored) |
+
+## Consequences
+
+- **Positive**:
+  - Responsive CLI (immediate feedback)
+  - Reliable long operations (queuing)
+  - Natural fit for infrastructure workflows
+  - Easy horizontal scaling (queue consumers)
+
+- **Negative**:
+  - Operational complexity (monitoring queues)
+  - Eventual consistency (state updates delayed)
+  - Testing asynchronous flows harder
+  - Webhook callback management
+
+## Monitoring
+
+```bash
+# Queue depth monitoring
+provisioning queue status
+# Output:
+# Queue: async          | Pending: 45    | Failed: 2      | Processed: 1,234
+# Queue: priority       | Pending: 0     | Failed: 0      | Processed: 589

+# ADR-006: Post-Quantum Cryptography via SecretumVault
+
+**Status**: Accepted | **Date**: 2025-01-16 | **Supersedes**: None
+
+## Context
+
+Cryptographic systems currently secure secrets, keys, and data. Emerging quantum computers
+threaten RSA, ECDSA, and other algorithms. The platform must be resistant to quantum attacks.
+
+## Decision
+
+Adopt post-quantum cryptography (PQC) via SecretumVault integration for all cryptographic
+operations. Hybrid encryption combines PQC with classical encryption for redundancy.
+
+## Rationale
+
+1. **Future-Proofing**: Data encrypted today with classical RSA will become vulnerable to quantum computers (10-20 year window)
+2. **Hybrid Approach**: Combine PQC with AES-256 to ensure at least one remains secure
+3. **NIST Standards**: Algorithms selected from NIST post-quantum competition (finalists and alternatives)
+4. **Legacy Support**: Fallback to classical crypto for non-quantum-resistant targets
+
+## Implementation
+
+### SecretumVault Integration
+
+```rust
+// /provisioning/platform/crates/vault-service/src/crypto.rs
+use secretumvault::{KeyPair, HybridEncryption};
+
+pub struct SecureVault {
+    hybrid: HybridEncryption,  // PQC + AES-256
+}
+
+impl SecureVault {
+    pub fn encrypt(&self, plaintext: &[u8]) -> Result<Vec<u8>> {
+        // PQC algorithms: CRYSTALS-Kyber (KEM), Falcon (signature)
+        // Classical: AES-256-GCM
+        // Hybrid result: both encryptions concatenated
+        self.hybrid.encrypt(plaintext)
+    }
+
+    pub fn decrypt(&self, ciphertext: &[u8]) -> Result<Vec<u8>> {
+        // Try PQC first, fallback to classical
+        self.hybrid.decrypt(ciphertext)
+    }
+}
+```
+
+### Algorithms
+
+**Key Encapsulation (KEM)**:
+- Primary: CRYSTALS-Kyber (Category 3, 1024-bit security)
+- Fallback: Elliptic Curve (X25519)
+
+**Signatures**:
+- Primary: Falcon (Category 3, fast)
+- Fallback: Ed25519
+
+**Encryption**:
+- Primary: AES-256-GCM (classical, well-tested)
+- Hybrid: Both PQC + AES-256 (double encryption)
+
+**Hash Functions**:
+- Primary: SHAKE256 (NIST standard)
+- Fallback: SHA-3-256
+
+### Migration Strategy
+
+**Phase 1 (Current)**: Hybrid encryption (PQC + classical)
+```text
+Secret → CRYSTALS-Kyber KEM → 256-bit key
+       → AES-256 encryption with key
+       → Ed25519 signature
+Result: Secure against both classical and quantum attacks
+```
+
+**Phase 2 (2030+)**: PQC-only if classical crypto broken
+```text
+Secret → CRYSTALS-Kyber KEM only
+       → Falcon signature only
+Fallback to classical available if PQC fails
+```
+
+### Usage
+
+**CLI**:
+```bash
+# Enable PQC for new secrets
+provisioning secret create myapp-key \
+  --encryption hybrid \          # PQC + AES-256
+  --key-rotation-days 365 \
+  --quantum-safe
+
+# Rotate to quantum-safe keys
+provisioning secret rotate --encryption hybrid --algorithm kyber
+
+# Check PQC status

+
+## Consequences
+
+- **Positive**:
+  - Resistant to quantum attacks
+  - NIST-approved algorithms
+  - Backward compatible (hybrid doesn't break classical crypto)
+  - Audit trail for compliance (SOC2, FIPS)
+  - Transparent to users (no behavior change)
+
+- **Negative**:
+  - Larger ciphertexts (PQC signatures 1-2KB vs classical 256 bytes)
+  - Slight performance overhead (10-15% slower encryption/decryption)
+  - Storage cost for larger keys
+  - Tooling support still emerging (most libraries support PQC)
+
+## Performance Impact
+
+| Operation | Classical | Hybrid (PQC+Classical) | Overhead |
+| ----------- | ----------- | ---------------------- | ---------- |
+| Key generation | 10ms | 25ms | 2.5x |
+| Encryption (1MB) | 50ms | 75ms | 1.5x |
+| Decryption (1MB) | 50ms | 75ms | 1.5x |
+| Signature generation | 5ms | 8ms | 1.6x |
+| Signature verification | 3ms | 5ms | 1.7x |
+
+**Mitigation**: Cache keys, use async encryption for large operations
+
+## Compliance

+# ADR-007: Multi-Layer Data Encryption Strategy
+
+**Status**: Accepted | **Date**: 2025-01-16 | **Supersedes**: None
+
+## Context
+
+Provisioning stores sensitive data: API credentials, database passwords, private keys,
+and configuration secrets. Data protection is required both in transit and at rest.
+
+## Decision
+
+Implement four encryption layers:
+1. **Encryption at Rest** - Database encryption, file encryption
+2. **Encryption in Transit** - TLS 1.3, mTLS for service communication
+3. **Field-Level Encryption** - Sensitive fields encrypted within application
+4. **End-to-End Encryption** - User data encrypted by client before sending
+
+## Architecture
+
+### Layer 1: At-Rest Encryption
+
+**Database Encryption** (SurrealDB):
+```sql
+-- All secrets table encrypted with AES-256-GCM
+CREATE TABLE secrets (
+    id: string,
+    name: string,
+    value: string ENCRYPT_AES256,      -- Encrypted at database level
+    key_id: string,                     -- Which key encrypted this
+    created_at: datetime,
+    rotated_at: datetime
+)
+```
+
+**File Encryption** (Persistent state):
+```rust
+// Orchestrator file-based state: encrypted with rotating keys
+let encrypted_state = AES256GCM::encrypt(
+    plaintext_state,
+    key_from_vault,
+    random_nonce
+);
+
+fs::write("orchestrator/state.enc", encrypted_state)?;
+```
+
+**Backup Encryption**:
+```bash
+# Backups automatically encrypted with PQC hybrid encryption
+provisioning backup create --type full --encryption hybrid
+# Output: backup-2025-01-16-ENCRYPTED.tar.gz
+# Encrypted with CRYSTALS-Kyber + AES-256
+```
+
+### Layer 2: Encryption in Transit
+
+**TLS 1.3** (Service to Service):
+```rust
+// All REST API endpoints TLS 1.3 only
+let server = HttpServer::new( | | {
+    App::new()
+        .wrap(
+            middleware::DefaultHeaders::new()
+                .add(("Strict-Transport-Security", "max-age=31536000"))
+        )
+})
+.bind_openssl("0.0.0.0:443", ssl_acceptor)?
+.run()
+.await?;
+```
+
+**mTLS** (Service-to-Service Authentication):
+```text
+Control-Center → Vault-Service
+  1. Verify Service certificate signed by internal CA
+  2. Verify certificate chain and revocation status
+  3. Check certificate common-name matches expected service
+  4. Proceed with encrypted communication
+```
+
+**Certificate Management**:
+```bash
+# Automatic certificate generation and rotation
+provisioning cert generate --service vault-service --ttl 90d --auto-renew
+provisioning cert rotate --all-services --force
+
+# Certificate verification
+provisioning cert verify --service orchestrator
+# Output:
+# Service: orchestrator
+# Certificate: vault-orchestrator.cert.pem
+# Valid: 2025-01-16 to 2025-04-16
+# Chain: ✓ Valid | Revocation: ✓ Checked
+```
+
+### Layer 3: Field-Level Encryption
+
+Sensitive fields encrypted within application logic:
+
+```rust
+// vault-service encrypts before storing
+pub struct Secret {
+    #[encrypt]  // Custom derive macro
+    pub value: String,
+
+    pub key_id: String,  // Unencrypted reference
+    pub created_at: DateTime<Utc>,
+}
+
+impl Serialize for Secret {
+    fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> {
+        // Encrypt value field during serialization
+        let encrypted = vault.encrypt(&self.value)?;
+        SerializeState {
+            value: encrypted,
+            key_id: &self.key_id,
+            created_at: self.created_at,
+        }.serialize(serializer)
+    }
+}
+```
+
+**Searchable Encryption** (for indexed fields):
+```rust
+// Hash values for indexing without decryption
+let search_hash = HMAC_SHA256(secret_value, search_key);
+db.create_index(search_hash);  // Index encrypted values
+
+// Search works on hash
+let results = db.query_by_index(search_hash);
+```
+
+### Layer 4: End-to-End Encryption
+
+User's client-side encryption:
+
+```nushell
+# User encrypts locally, only encrypted value sent
+let secret = "api-key-12345"
+let encrypted = provisioning secret encrypt --plaintext $secret --user-key-id mykey
+provisioning secret upload --encrypted $encrypted
+
+# Only user with private key can decrypt
+provisioning secret decrypt --encrypted-value $encrypted --user-key-id mykey
+```
+
+## Key Rotation
+
+**Automatic Rotation**:
+```bash
+# Rotate encryption keys every 90 days
+provisioning key rotate --policy auto --interval 90d
+
+# Timeline:
+# Day 1: New key generated, becomes "active"
+# Day 1-90: Old key still used for decryption
+# Day 90: Old key marked "retired", new key only for encryption
+# Day 180: Old key deleted from vault (audit trail kept)
+```
+
+**Re-encryption During Rotation**:
+```text
+Old Key: secret-key-2024
+  ↓ decrypt
+Plaintext (never stored)
+  ↓ encrypt
+New Key: secret-key-2025
+  ↓ store
+Database updated with new ciphertext
+```
+
+## Data Classification
+
+| Classification | At-Rest | In-Transit | Field-Level | E2E |
+| ---------------- | --------- | ----------- | ------------- | ----- |
+| Public | Optional | TLS 1.3 | No | No |
+| Internal | AES-256 | TLS 1.3 + mTLS | Optional | No |
+| Confidential | AES-256 | TLS 1.3 + mTLS | Yes | Optional |
+| Restricted | Hybrid PQC | TLS 1.3 + mTLS | Yes | Yes |
+
+## Performance Optimization
+
+**Caching** (reduce decryption overhead):
+```rust
+// Cache decrypted secrets with TTL
+let cache = LruCache::new(1000);
+cache.insert(key_id, (plaintext, expiration));
+
+// Subsequent requests use cache
+if let Some((value, exp)) = cache.get(key_id) {
+    if exp > now() {
+        return Ok(value);  // No decryption overhead
+    }
+}
+```
+
+**Lazy Decryption**:
+```rust
+// Don't decrypt until actually accessed
+pub struct EncryptedSecret {
+    ciphertext: Vec<u8>,
+    key_id: String,
+}
+
+impl EncryptedSecret {
+    pub fn decrypt_on_read(&self, vault: &Vault) -> Result<String> {
+        vault.decrypt(&self.ciphertext, &self.key_id)
+    }
+}
+```
+
+## Compliance
+
+- **FIPS 140-2**: Encryption algorithms validated
+- **PCI DSS**: Encryption for payment data
+- **GDPR**: Data protection by design
+- **HIPAA**: Encryption for healthcare data
+- **SOC2**: Encryption controls and key management
+
+## Consequences
+
+- **Positive**:
+  - Defense in depth (multiple encryption layers)
+  - Quantum-safe (hybrid PQC)
+  - Compliance-ready
+  - Transparent to most operations
+
+- **Negative**:
+  - Performance overhead (1-5% latency increase)
+  - Operational complexity (key management)
+  - Storage overhead (encrypted data ~10% larger)
+  - Debugging harder (encrypted data opaque)

+# ADR-008: Unified Observability Stack (Metrics, Logs, Traces)
+
+**Status**: Accepted | **Date**: 2025-01-16 | **Supersedes**: None
+
+## Context
+
+Distributed 12-microservice architecture requires observability to understand system behavior, diagnose failures, and optimize performance.
+
+## Decision
+
+Implement unified observability using three pillars:
+1. **Metrics** - Prometheus/VictoriaMetrics for time-series data
+2. **Logs** - ELK Stack (Elasticsearch, Logstash, Kibana) or Loki
+3. **Traces** - Jaeger for distributed request tracing
+
+## Rationale
+
+1. **Prometheus Metrics**: Industry standard, minimal overhead, powerful querying
+2. **Structured Logging**: JSON logs for machine parsing, full-text search in Kibana
+3. **Distributed Traces**: End-to-end request tracking across all 12 services
+4. **Correlation**: Unified correlation IDs linking metrics, logs, traces
+
+## Implementation
+
+### Metrics Layer
+
+**Prometheus** (all services expose `/metrics` endpoint):
+
+```rust
+// Every service exports metrics
+use prometheus::{Counter, Histogram, Registry};
+
+lazy_static::lazy_static! {
+    static ref HTTP_REQUESTS: Counter = Counter::new("http_requests_total", "Total HTTP requests").unwrap();
+    static ref RESPONSE_TIME: Histogram = Histogram::new("http_response_time_seconds", "HTTP response time").unwrap();
+}
+
+#[get("/api/v1/workspaces")]
+async fn list_workspaces() -> HttpResponse {
+    let timer = RESPONSE_TIME.start_timer();
+    HTTP_REQUESTS.inc();
+
+    // Business logic
+    let workspaces = db.list_workspaces().await;
+
+    timer.observe_duration();
+    HttpResponse::Ok().json(workspaces)
+}
+```
+
+**Key Metrics** (per service):
+
+| Metric | Type | Purpose |
+| -------- | ------ | --------- |
+| `http_requests_total` | Counter | API call volume |
+| `http_response_time_seconds` | Histogram | API latency distribution |
+| `workflow_executions_total` | Counter | Workflow count |
+| `workflow_duration_seconds` | Histogram | Workflow execution time |
+| `database_query_duration_seconds` | Histogram | DB query performance |
+| `cache_hits_total` | Counter | Cache effectiveness |
+| `secrets_decryption_duration_seconds` | Histogram | Vault latency |
+
+**Alerting Rules** (Prometheus alerts):
+
+```yaml
+# provisioning/monitoring/prometheus-rules.yaml
+groups:
+- name: provisioning
+  rules:
+  - alert: ServiceDown
+    expr: up{job="provisioning"} == 0
+    for: 5m
+    labels:
+      severity: critical
+    annotations:
+      summary: "Service {{ $labels.service }} is down"
+
+  - alert: HighLatency
+    expr: histogram_quantile(0.99, http_response_time_seconds) > 1
+    for: 10m
+    labels:
+      severity: warning
+    annotations:
+      summary: "High API latency: {{ $value }}s"
+
+  - alert: WorkflowFailureRate
+    expr: (increase(workflow_failures_total[5m]) / increase(workflow_executions_total[5m])) > 0.05
+    labels:
+      severity: critical
+    annotations:
+      summary: "Workflow failure rate exceeds 5%"
+```
+
+### Logging Layer
+
+**Structured Logging** (JSON, machine-parseable):
+
+```rust
+// Every service logs in JSON with context
+use slog::{Logger, o, info, warn, error};
+use slog_json_compact::JsonCompact;
+
+let logger = Logger::root(
+    JsonCompact::new(io::stdout()).fuse(),
+    o!("service" => "control-center", "version" => "1.0.0")
+);
+
+info!(logger, "Workspace created";
+    "workspace_id" => "ws-123",
+    "user_id" => "user-456",
+    "region" => "us-east-1",
+    "duration_ms" => 234,
+    "correlation_id" => "corr-789"
+);
+```
+
+**Log Aggregation** (Loki):
+
+```yaml
+# Loki config: labels for efficient querying
+scrape_configs:
+- job_name: provisioning
+  static_configs:
+  - targets:
+    - localhost
+    labels:
+      service: control-center
+      environment: production
+      region: us-east-1
+```
+
+**Log Analysis**:
+
+```bash
+# LogQL queries in Kibana/Grafana
+# Find errors in last 5 minutes
+{service="control-center", level="error"} | json | level="error"
+
+# Latency distribution by endpoint
+{service="control-center"} | json | histogram(duration_ms)
+
+# Error rate by user
+{service="vault-service"} | json | errors_by_user(user_id)
+```
+
+### Tracing Layer
+
+**Distributed Tracing** (Jaeger):
+
+```rust
+use opentelemetry::{global, sdk::trace as sdktrace};
+use opentelemetry_jaeger::new_pipeline;
+
+// Initialize tracing
+let tracer = new_pipeline()
+    .install_simple()
+    .unwrap();
+
+// Instrument requests with spans
+#[tracing::instrument(skip(req))]
+async fn create_workspace(req: CreateWorkspaceRequest) -> Result<Workspace> {
+    let span = global::tracer("control-center").start("create_workspace");
+
+    // Each internal call creates child span
+    let config = fetch_config().await?;  // Traced automatically
+
+    let workspace = db.create(req).await?;  // Traced automatically
+
+    tracing::info_span!("post_creation_hook").in_scope( | | {
+        send_notification(&workspace)?;
+    });
+
+    Ok(workspace)
+}
+```
+
+**Trace Visualization** (Jaeger UI):
+
+```text
+Request: POST /api/v1/workspaces
+├─ span: api_handler (10ms)
+│  ├─ span: validate_input (2ms)
+│  ├─ span: fetch_config (100ms)
+│  │  ├─ span: control-center_api_call (100ms) [service: control-center]
+│  ├─ span: db_create (50ms)
+│  └─ span: post_creation_hook (200ms)
+│     ├─ span: notification_send (150ms) [service: notification-service]
+│     └─ span: webhook_call (50ms)
+└─ Total: 362ms
+```
+
+## Correlation ID
+
+All requests traced by correlation ID:
+
+```text
+Client Request
+  → Generate: correlation_id = "corr-abc123"
+  → Pass in X-Correlation-ID header
+  ↓
+Control-Center
+  → Receive: correlation_id from header
+  → Log: {"correlation_id": "corr-abc123", ...}
+  → Call Orchestrator with X-Correlation-ID header
+  ↓
+Orchestrator
+  → Inherit correlation_id from header
+  → Create spans: correlation_id = "corr-abc123"
+  → Call Vault-Service with X-Correlation-ID header
+  ↓
+All logs, metrics, traces tagged with same correlation_id
+→ Easy to correlate across services
+```
+
+## Dashboard Queries
+
+**Real-Time Health Dashboard**:
+
+```text
+Prometheus metrics
+- Service health (up/down)
+- Request rate (req/sec)
+- Error rate (errors/sec)
+- P99 latency (milliseconds)
+- CPU/Memory per service
+- Cache hit rate
+
+Grafana visualizations
+- Time-series graphs
+- Heatmaps for latency distribution
+- Error rate alerts
+- Dependency graph (which services call which)
+```
+
+**SLO Monitoring**:
+
+```yaml
+# Service Level Objectives
+objectives:
+- name: API Availability
+  expr: up{service="control-center"} > 0.9995
+  target: 99.95%
+  window: 30d
+
+- name: API Latency (P99)
+  expr: histogram_quantile(0.99, http_response_time_seconds) < 1
+  target: <1 second
+  window: 5m
+
+- name: Workflow Success Rate
+  expr: (1 - (increase(workflow_failures_total[5m]) / increase(workflow_executions_total[5m]))) > 0.999
+  target: 99.9%
+  window: 5m
+```
+
+## Performance Considerations
+
+| Overhead | Cost | Mitigation |
+| ---------- | ------ | ----------- |
+| Metrics collection | 2-5% CPU | Sampling (10% requests) |
+| Logging to ELK | 5-10% latency | Async logging |
+| Trace sampling | Variable | 10% sample rate default |
+| Disk storage | 100GB/day | Retention: 7 days (metrics), 30 days (logs) |

+# ADR-009: SLO and Error Budget Management
+
+**Status**: Accepted | **Date**: 2025-01-16 | **Supersedes**: None
+
+## Context
+
+Provisioning provides infrastructure automation for production systems. Failures cascade to
+customer infrastructure. SLOs balance reliability investment with development velocity.
+
+## Decision
+
+Define service level objectives (SLOs) for each critical service with monitored error budgets. Availability targets guide operational decisions.
+
+## SLOs Defined
+
+### Tier 1: Critical Infrastructure Services
+
+**Availability Target**: 99.99% (52.6 minutes downtime/year)
+
+| Service | Metric | Target | Measurement |
+| --------- | -------- | -------- | ------------- |
+| Orchestrator | Workflow success rate | 99.99% | Failed / Total workflows (5m window) |
+| Vault-Service | Secret retrieval | 99.99% | Failed requests / Total requests (5m) |
+| Control-Center | API availability | 99.99% | HTTP 5xx / Total requests (5m) |
+
+### Tier 2: Supporting Services
+
+**Availability Target**: 99.9% (8.76 hours downtime/year)
+
+| Service | Metric | Target | Measurement |
+| --------- | -------- | -------- | ------------- |
+| Extension-Registry | API availability | 99.9% | HTTP 5xx / Total requests (5m) |
+| AI-Service | Response time | 99.9% | Queries > 10s / Total queries (5m) |
+| Detector | Analysis completion | 99.9% | Failed analyses / Total analyses (5m) |
+
+### Tier 3: Enhancement Services
+
+**Availability Target**: 99.5% (3.65 days downtime/year)
+
+| Service | Metric | Target | Measurement |
+| --------- | -------- | -------- | ------------- |
+| RAG | Index freshness | 99.5% | Stale results / Total queries (5m) |
+| MCP-Server | Tool availability | 99.5% | Unavailable tools / Total tools (5m) |
+
+## Error Budget Management
+
+### Error Budget Calculation
+
+```text
+SLO Target: 99.99% (Tier 1)
+Available Errors: 100% - 99.99% = 0.01%
+Error Budget: 0.01% × Total Requests
+
+Example:
+- 1 million requests/day
+- Error budget = 10,000 allowed errors/day
+- If 5,000 errors already occurred
+- Remaining budget = 5,000 errors (50% of budget consumed)
+```
+
+### Error Budget Policies
+
+**Burn Rate** (error consumption speed):
+
+```text
+Slow Burn (< 1x rate): Safe, continue normal operations
+Fast Burn (1-2x rate): Monitor, may trigger incident response
+Critical Burn (> 2x rate): Stop all deployments, emergency incident
+
+Example:
+- Daily error budget: 10,000 errors
+- 1x burn rate: 10,000 errors/day
+- 2x burn rate: 20,000 errors/day (double consumption)
+```
+
+**Action Triggers**:
+
+| Burn Rate | Budget Remaining | Action |
+| ----------- | ------------------ | -------- |
+| < 1x | > 50% | Deploy freely, run experiments |
+| 1x | 25-50% | Code freeze for non-critical features |
+| 2x | 10-25% | No deployments except hotfixes |
+| > 2x | < 10% | Emergency incident, all hands on deck |
+
+### Prometheus Rules for Error Budget

+    disallow: feature releases
+    disallow: large refactors
+    disallow: canary > 25%
+    frequency: 1 deploy/day maximum
+}
+```
+
+### Red Light Conditions (Error Budget Exhausted)
+
+```text
+if remaining_error_budget <= 10% {
+    allow: emergency hotfixes only
+    disallow: all non-critical changes
+    disallow: any new deployments
+    action: incident response required
+    escalation: VP Engineering approval needed
+}
+```
+
+## SLO Review Cycle
+
+**Monthly**:
+- Review SLI data vs SLO targets
+- Identify services approaching budget limits
+- Plan remediation for low-performing services
+
+**Quarterly**:
+- Review SLO targets against business requirements
+- Adjust targets based on incident patterns
+- Plan infrastructure improvements
+
+**Annually**:
+- SLO target review with product/ops leadership
+- Align SLOs with business goals
+- Plan year-long reliability improvements
+
+## Consequences
+
+- **Positive**:
+  - Data-driven deployment decisions
+  - Balance between innovation and reliability
+  - Early warning system for degradation
+  - Alignment between dev and ops
+
+- **Negative**:
+  - Developers may resist deployment restrictions
+  - Overhead of monitoring error budgets
+  - Complex to communicate to stakeholders
+  - SLO targets may feel arbitrary

-# ADR-010: Configuration File Format Strategy
-
-**Status**: Accepted
-**Date**: 2025-12-03
-**Decision Makers**: Architecture Team
-**Implementation**: Multi-phase migration (KCL workspace configs + template reorganization)
-
----
-
-## Context
-
-The provisioning project historically used a single configuration format (YAML/TOML environment variables) for all purposes. As the system evolved,
-different parts naturally adopted different formats:
-
-- **TOML** for modular provider and platform configurations (`providers/*.toml`, `platform/*.toml`)
-- **KCL** for infrastructure-as-code definitions with type safety
-- **YAML** for workspace metadata
-
-However, the workspace configuration remained in **YAML** (`provisioning.yaml`),
-creating inconsistency and leaving type-unsafe configuration handling. Meanwhile,
-complete KCL schemas for workspace configuration were designed but unused.
-
-**Problem**: Three different formats in the same system without documented rationale or consistent patterns.
-
----
-
-## Decision
-
-Adopt a **three-format strategy** with clear separation of concerns:
-
-| Format | Purpose | Use Cases |
-| -------- | --------- | ----------- |
-| **KCL** | Infrastructure as Code & Schemas | Workspace config, infrastructure definitions, type-safe validation |
-| **TOML** | Application Configuration & Settings | System defaults, provider settings, user preferences, interpolation |
-| **YAML** | Metadata & Kubernetes Resources | K8s manifests, tool metadata, version tracking, CI/CD resources |
-
----
-
-## Implementation Strategy
-
-### Phase 1: Documentation (Complete)
-
-Define and document the three-format approach through:
-
-1. **ADR-010** (this document) - Rationale and strategy
-2. **CLAUDE.md updates** - Quick reference for developers
-3. **Configuration hierarchy** - Explicit precedence rules
-
-### Phase 2: Workspace Config Migration (In Progress)
-
-**Migrate workspace configuration from YAML to KCL**:
-
-1. Create comprehensive workspace configuration schema in KCL
-2. Implement backward-compatible config loader (KCL first, fallback to YAML)
-3. Provide migration script to convert existing workspaces
-4. Update workspace initialization to generate KCL configs
-
-**Expected Outcome**:
-
-- `workspace/config/provisioning.ncl` (KCL, type-safe, validated)
-- Full schema validation with semantic versioning checks
-- Automatic validation at config load time
-
-### Phase 3: Template File Reorganization (In Progress)
-
-**Move template files to proper directory structure and correct extensions**:
-
-```bash
-Previous (KCL):
-  provisioning/kcl/templates/*.k  (had Nushell/Jinja2 code, not KCL)
-
-Current (Nickel):
-  provisioning/templates/
-    ├── nushell/*.nu.j2
-    ├── config/*.toml.j2
-    ├── nickel/*.ncl.j2
-    └── README.md
-```
-
-**Expected Outcome**:
-
-- Templates properly classified and discoverable
-- KCL validation passes (15/16 errors eliminated)
-- Template system clean and maintainable
-
----
-
-## Rationale for Each Format
-
-### KCL for Workspace Configuration
-
-**Why KCL over YAML or TOML?**
-
-1. **Type Safety**: Catch configuration errors at schema validation time, not runtime
-
-   ```kcl
-   schema WorkspaceDeclaration:
-       metadata: Metadata
-       check:
-           regex.match(metadata.version, r"^\d+\.\d+\.\d+$"), 
-               "Version must be semantic versioning"
-   ```
-
-1. **Schema-First Development**: Schemas are first-class citizens
-   - Document expected structure upfront
-   - IDE support for auto-completion
-   - Enforce required fields and value ranges
-
-2. **Immutable by Default**: Infrastructure configurations are immutable
-   - Prevents accidental mutations
-   - Better for reproducible deployments
-   - Aligns with PAP principle: "configuration-driven, not hardcoded"
-
-3. **Complex Validation**: KCL supports sophisticated validation rules
-   - Semantic versioning validation
-   - Dependency checking
-   - Cross-field validation
-   - Range constraints on numeric values
-
-4. **Ecosystem Consistency**: KCL is already used for infrastructure definitions
-   - Server configurations use KCL
-   - Cluster definitions use KCL
-   - Taskserv definitions use KCL
-   - Using KCL for workspace config maintains consistency
-
-5. **Existing Schemas**: `provisioning/kcl/generator/declaration.ncl` already defines complete workspace schemas
-   - No design work needed
-   - Production-ready schemas
-   - Well-tested patterns
-
-### TOML for Application Configuration
-
-**Why TOML for settings?**
-
-1. **Hierarchical Structure**: Native support for nested configurations
-
-   ```toml
-   [http]
-   use_curl = false
-   timeout = 30
-
-   [debug]
-   enabled = false
-   log_level = "info"
-   ```
-
-2. **Interpolation Support**: Dynamic variable substitution
-
-   ```toml
-   base_path = "/Users/home/provisioning"
-   cache_path = "{{base_path}}/.cache"
-   ```
-
-3. **Industry Standard**: Widely used for application configuration (Rust, Python, Go)
-
-4. **Human Readable**: Clear, explicit, easy to edit
-
-5. **Validation Support**: Schema files (`.schema.toml`) for validation
-
-**Use Cases**:
-
-- System defaults: `provisioning/config/config.defaults.toml`
-- Provider settings: `workspace/config/providers/*.toml`
-- Platform services: `workspace/config/platform/*.toml`
-- User preferences: User config files
-
-### YAML for Metadata and Kubernetes Resources
-
-**Why YAML for metadata?**
-
-1. **Kubernetes Compatibility**: YAML is K8s standard
-   - K8s manifests use YAML
-   - Consistent with ecosystem
-   - Familiar to DevOps engineers
-
-2. **Lightweight**: Good for simple data structures
-
-   ```yaml
-   workspace:
-     name: "librecloud"
-     version: "1.0.0"
-     created: "2025-10-06T12:29:43Z"
-   ```
-
-3. **Version Control**: Human-readable format
-   - Diffs are clear and meaningful
-   - Git-friendly
-   - Comments supported
-
-**Use Cases**:
-
-- K8s resource definitions
-- Tool metadata (versions, sources, tags)
-- CI/CD configuration files
-- User workspace metadata (during transition)
-
----
-
-## Configuration Hierarchy (Priority)
-
-**When loading configuration, use this precedence (highest to lowest)**:
-
-1. **Runtime Arguments** (highest priority)
-   - CLI flags passed to commands
-   - Explicit user input
-
-2. **Environment Variables** (PROVISIONING_*)
-   - Override system settings
-   - Deployment-specific overrides
-   - Secrets via env vars
-
-3. **User Configuration** (Centralized)
-   - User preferences: `~/.config/provisioning/user_config.yaml`
-   - User workspace overrides: `workspace/config/local-overrides.toml`
-
-4. **Infrastructure Configuration**
-   - Workspace KCL config: `workspace/config/provisioning.ncl`
-   - Platform services: `workspace/config/platform/*.toml`
-   - Provider configs: `workspace/config/providers/*.toml`
-
-5. **System Defaults** (lowest priority)
-   - System config: `provisioning/config/config.defaults.toml`
-   - Schema defaults: defined in KCL schemas
-
----
-
-## Migration Path
-
-### For Existing Workspaces
-
-1. **Migration Path**: Config loader checks for `.ncl` first, then falls back to `.yaml` for legacy systems
-
-   ```nushell
-   # Try Nickel first (current)
-   if ($config_nickel | path exists) {
-       let config = (load_nickel_workspace_config $config_nickel)
-   } else if ($config_yaml | path exists) {
-       # Legacy YAML support (from pre-migration)
-       let config = (open $config_yaml)
-   }
-   ```
-
-2. **Automatic Migration**: Migration script converts YAML/KCL → Nickel
-
-   ```bash
-   provisioning workspace migrate-config --all
-   ```
-
-3. **Validation**: New KCL configs validated against schemas
-
-### For New Workspaces
-
-1. **Generate KCL**: Workspace initialization creates `.k` files
-
-   ```bash
-   provisioning workspace create my-workspace
-   # Creates: workspace/my-workspace/config/provisioning.ncl
-   ```
-
-2. **Use Existing Schemas**: Leverage `provisioning/kcl/generator/declaration.ncl`
-
-3. **Schema Validation**: Automatic validation during config load
-
----
-
-## File Format Guidelines for Developers
-
-### When to Use Each Format
-
-**Use KCL for**:
-
-- Infrastructure definitions (servers, clusters, taskservs)
-- Configuration with type requirements
-- Schema definitions
-- Any config that needs validation rules
-- Workspace configuration
-
-**Use TOML for**:
-
-- Application settings (HTTP client, logging, timeouts)
-- Provider-specific settings
-- Platform service configuration
-- User preferences and overrides
-- System defaults with interpolation
-
-**Use YAML for**:
-
-- Kubernetes manifests
-- CI/CD configuration (GitHub Actions, GitLab CI)
-- Tool metadata
-- Human-readable documentation files
-- Version control metadata
-
----
-
-## Consequences
-
-### Benefits
-
-✅ **Type Safety**: KCL schema validation catches config errors early
-✅ **Consistency**: Infrastructure definitions and configs use same language
-✅ **Maintainability**: Clear separation of concerns (IaC vs settings vs metadata)
-✅ **Validation**: Semantic versioning, required fields, range checks
-✅ **Tooling**: IDE support for KCL auto-completion
-✅ **Documentation**: Self-documenting schemas with descriptions
-✅ **Ecosystem Alignment**: TOML for settings (Rust standard), YAML for K8s
-
-### Trade-offs
-
-⚠️ **Learning Curve**: Developers must understand three formats
-⚠️ **Migration Effort**: Existing YAML configs need conversion
-⚠️ **Tooling Requirements**: KCL compiler needed (already a dependency)
-
-### Risk Mitigation
-
-1. **Documentation**: Clear guidelines in CLAUDE.md
-2. **Backward Compatibility**: YAML support maintained during transition
-3. **Automation**: Migration scripts for existing workspaces
-4. **Gradual Migration**: No hard cutoff, both formats supported for extended period
-
----
-
-## Template File Reorganization
-
-### Problem
-
-Currently, 15/16 files in `provisioning/kcl/templates/` have `.k` extension but contain Nushell/Jinja2 code, not KCL:
-
-```nushell
-provisioning/kcl/templates/
-├── server.ncl          # Actually Nushell/Jinja2 template
-├── taskserv.ncl        # Actually Nushell/Jinja2 template
-└── ...               # 15 more template files
-```
-
-This causes:
-
-- KCL validation failures (96.6% of errors)
-- Misclassification (templates in KCL directory)
-- Confusing directory structure
-
-### Solution
-
-Reorganize into type-specific directories:
-
-```bash
-provisioning/templates/
-├── nushell/           # Nushell code generation (*.nu.j2)
-│   ├── server.nu.j2
-│   ├── taskserv.nu.j2
-│   └── ...
-├── config/            # Config file generation (*.toml.j2, *.yaml.j2)
-│   ├── provider.toml.j2
-│   └── ...
-├── kcl/               # KCL file generation (*.k.j2)
-│   ├── workspace.ncl.j2
-│   └── ...
-└── README.md
-```
-
-### Outcome
-
-✅ Correct file classification
-✅ KCL validation passes completely
-✅ Clear template organization
-✅ Easier to discover and maintain templates

+# ADR-010: Automated Incident Response and Self-Healing
+
+**Status**: Accepted | **Date**: 2025-01-16 | **Supersedes**: None
+
+## Context
+
+Production incidents require rapid response to minimize impact. Manual responses are slow
+and error-prone. Automated incident response reduces MTTR (Mean Time to Recovery).
+
+## Decision
+
+Implement autonomous incident response system that detects issues and automatically
+remediates without human intervention.
+
+## Automation Levels
+
+### Level 1: Automatic Detection
+
+```text
+Monitoring Alert
+    ↓ (triggered)
+    ↓
+Detection Engine
+    ├─ Analyze alert severity
+    ├─ Correlate related alerts
+    ├─ Assess impact
+    └─ Classify incident type
+```
+
+### Level 2: Automated Response
+
+```text
+Incident Classification
+    ↓
+Remediation Playbook Selection
+    ↓
+Automated Mitigation Steps
+    ├─ Scale up resources
+    ├─ Failover services
+    ├─ Restart components
+    ├─ Clear caches
+    └─ Update routing
+```
+
+### Level 3: Escalation and Validation
+
+```text
+Auto-remediation Attempted
+    ↓
+Monitor for Recovery
+    ├─ Success → Close incident
+    └─ Failure → Escalate to human
+    ↓ (human intervention required)
+    ↓
+On-call Engineer Notified
+```
+
+## Implementation
+
+### Incident Detection
+
+```rust
+pub struct IncidentDetector {
+    alerts: Arc<RwLock<VecDeque<Alert>>>,
+    correlation_window: Duration,
+    detectors: HashMap<String, Box<dyn IncidentClassifier>>,
+}
+
+impl IncidentDetector {
+    pub async fn detect(&self, alert: Alert) -> Option<Incident> {
+        // Correlate with recent alerts
+        let related_alerts = self.correlate_alerts(&alert).await;
+
+        // Classify incident type
+        let incident_type = self.classify(&alert, &related_alerts).await?;
+
+        // Assess severity
+        let severity = self.assess_severity(&incident_type, &related_alerts).await;
+
+        Some(Incident {
+            id: generate_id(),
+            incident_type,
+            severity,
+            timestamp: Utc::now(),
+            alerts: vec![alert],
+            related_alerts,
+        })
+    }
+
+    async fn correlate_alerts(&self, alert: &Alert) -> Vec<Alert> {
+        let alerts = self.alerts.read().await;
+        alerts
+            .iter()
+            .filter( | a | {
+                // Alerts from same service within window
+                a.service == alert.service
+                    && (Utc::now() - a.timestamp) < self.correlation_window
+            })
+            .cloned()
+            .collect()
+    }
+
+    async fn classify(&self, alert: &Alert, related: &[Alert]) -> Option<IncidentType> {
+        // Use machine learning to classify incident type
+        // Consider: alert patterns, historical data, service dependencies
+        Some(IncidentType::HighLatency)
+    }
+}
+```
+
+### Automated Remediation
+
+```rust
+pub struct RemediationEngine {
+    playbooks: HashMap<IncidentType, RemediationPlaybook>,
+}
+
+impl RemediationEngine {
+    pub async fn remediate(&self, incident: &Incident) -> RemediationResult {
+        // Select appropriate playbook
+        let playbook = self.playbooks
+            .get(&incident.incident_type)
+            .ok_or("No playbook for incident type")?;
+
+        // Execute remediation steps in sequence
+        let mut results = Vec::new();
+
+        for step in &playbook.steps {
+            match step {
+                RemediationStep::ScaleService { service, target_replicas } => {
+                    results.push(self.scale_service(service, *target_replicas).await?);
+                },
+                RemediationStep::FailoverService { service, target_region } => {
+                    results.push(self.failover_service(service, target_region).await?);
+                },
+                RemediationStep::RestartService { service } => {
+                    results.push(self.restart_service(service).await?);
+                },
+                RemediationStep::ClearCache { service } => {
+                    results.push(self.clear_cache(service).await?);
+                },
+            }
+
+            // Check if remediation worked
+            tokio::time::sleep(Duration::from_secs(30)).await;
+            if self.is_healthy(&incident.incident_type).await {
+                return Ok(RemediationResult {
+                    success: true,
+                    steps_executed: results,
+                });
+            }
+        }
+
+        // If still not healthy, escalate
+        Ok(RemediationResult {
+            success: false,
+            steps_executed: results,
+        })
+    }
+}
+```
+
+### Runbook Example: High Latency
+
+```yaml
+# runbooks/high-latency-response.yaml
+incident_type: high_latency
+severity_threshold: 200ms
+
+response:

+
+### Nushell Implementation
+
+```nushell
+def respond-to-high-latency [] {

+
+    # Step 1: Scale up API service
+    let scale_result = (

+            --window 5m
+    )
+
+    if $latency < 200 {
+        print "✓ Latency recovered to acceptable levels"
+        return 0
+    }
+
+    # Step 4: Failover if still high
+    print "Latency still high, initiating failover..."
+    provisioning failover \

+    } else {
+        print "✗ Auto-remediation failed, escalating"
+        return 1
+    }
+}
+```
+
+## Self-Healing Patterns
+
+### Automatic Restart on Crash
+
+```text
+Service Crash Detected
+    ↓
+Health Check Failed 3 Times
+    ↓
+Automatic Restart Triggered
+    ├─ Wait 5 seconds (backoff)
+    ├─ Start service
+    ├─ Verify startup (30s timeout)
+    └─ Health check passes
+    ↓
+Service Restored
+```
+
+### Automatic Config Rollback
+
+```rust
+pub async fn handle_config_deployment_failure(
+    deployment_id: &str,
+    error: &DeploymentError,
+) -> Result<()> {
+    // If deployment fails due to config error
+    if error.is_config_related() {
+        log::error!("Config deployment failed: {:?}", error);
+
+        // Automatically rollback to last known-good config
+        let previous_config = fetch_last_good_config().await?;
+        apply_config(previous_config).await?;
+
+        // Notify team
+        notify_team("Config rollback triggered automatically").await?;
+
+        return Ok(());
+    }
+
+    Err(Box::new(error.clone()))
+}
+```
+
+## Escalation Criteria
+
+```nickel
+{
+  escalation_rules = [
+    {
+      condition = "remediation_attempts > 3",
+      action = "escalate_to_oncall",

+    }
+  ]
+}
+```
+
+## Learning from Incidents
+
+```rust
+pub async fn post_incident_analysis(incident: &Incident) {
+    // Log incident metrics
+    log_incident_metrics(incident).await;
+
+    // Identify improvements
+    let improvements = analyze_incident_response(incident).await;
+
+    // Update playbooks based on effectiveness
+    for improvement in improvements {
+        update_playbook(&improvement).await;
+    }
+
+    // Generate post-mortem
+    generate_postmortem(incident).await;
+}
+
+async fn analyze_incident_response(incident: &Incident) -> Vec<PlaybookImprovement> {
+    let mttr = incident.resolution_time;
+    let automation_effective = mttr < Duration::from_secs(300);  // < 5 minutes
+
+    if !automation_effective {
+        // Escalation or playbook was ineffective
+        // Analyze why and suggest improvements
+        vec![
+            PlaybookImprovement {
+                remediation_step: "scale_service".to_string(),
+                suggestion: "Increase target replicas from 50% to 100%".to_string(),
+            },
+        ]
+    } else {
+        vec![]
+    }
+}
+```
+
+## Monitoring Automation Effectiveness
+
+```bash
+# Incident metrics
+provisioning metrics incident-automation \
+    --metric success_rate \
+    --metric mttr \
+    --metric escalation_rate \
+    --metric false_positive_rate
+
+# Output:
+# Automation Success Rate: 87%
+# Average MTTR: 4m 23s (Target: <5m)
+# Escalation Rate: 13% (Target: <5%)
+# False Positive Rate: 2% (Target: <1%)
+```
+
+## Safety Mechanisms
+
+1. **Automatic Rollback**: Failed remediations automatically rollback
+2. **Circuit Breaker**: Stop retries if remediation repeatedly fails
+3. **Escalation Triggers**: Escalate if not resolved in N attempts
+4. **Rate Limiting**: Don't repeatedly try same remediation
+5. **Blast Radius Limits**: Limit changes to prevent cascading failures
+
+## Consequences
+
+- **Positive**:
+  - Reduced MTTR from 30+ minutes to <5 minutes
+  - Fewer manual escalations
+  - Better system resilience
+  - Faster incident response at 3 AM
+
+- **Negative**:
+  - Automation can cause unintended side effects
+  - Requires comprehensive testing
+  - Complex to debug if automation fails
+  - False positives possible

-# ADR-011: Migration from KCL to Nickel
-
-**Status**: Implemented
-**Date**: 2025-12-15
-**Decision Makers**: Architecture Team
-**Implementation**: Complete for platform schemas (100%)
-
----
-
-## Context
-
-The provisioning platform historically used KCL (KLang) as the primary infrastructure-as-code language for all configuration schemas. As the system
-evolved through four migration phases (Foundation, Core, Complex, Highly Complex), KCL's limitations became increasingly apparent:
-
-### Problems with KCL
-
-1. **Complex Type System**: Heavyweight schema system with extensive boilerplate
-   - `schema Foo(bar.Baz)` inheritance creates rigid hierarchies
-   - Union types with `null` don't work well in type annotations
-   - Schema modifications propagate breaking changes
-
-2. **Limited Flexibility**: Schema-first approach is too rigid for configuration evolution
-   - Difficult to extend types without modifying base schemas
-   - No easy way to add custom fields without validation conflicts
-   - Hard to compose configurations dynamically
-
-3. **Import System Overhead**: Non-standard module imports
-   - `import provisioning.lib as lib` pattern differs from ecosystem standards
-   - Re-export patterns create complexity in extension systems
-
-4. **Performance Overhead**: Compile-time validation adds latency
-   - Schema validation happens at compile time
-   - Large configuration files slow down evaluation
-   - No lazy evaluation built-in
-
-5. **Learning Curve**: KCL is Python-like but with unique patterns
-   - Team must learn KCL-specific semantics
-   - Limited ecosystem and tooling support
-   - Difficult to hire developers familiar with KCL
-
-### Project Needs
-
-The provisioning system required:
-
-- **Greater flexibility** in composing configurations
-- **Better performance** for large-scale deployments
-- **Extensibility** without modifying base schemas
-- **Simpler mental model** for team learning
-- **Clean exports** to JSON/TOML/YAML formats
-
----
-
-## Decision
-
-**Adopt Nickel as the primary infrastructure-as-code language** for all schema definitions, configuration composition, and deployment declarations.
-
-### Key Changes
-
-1. **Three-File Pattern per Module**:
-   - `{module}_contracts.ncl` - Type definitions using Nickel contracts
-   - `{module}_defaults.ncl` - Default values for all fields
-   - `{module}.ncl` - Instances combining both, with hybrid interface
-
-2. **Hybrid Interface** (4 levels of access):
-   - **Level 1**: Direct access to defaults (inspection, reference)
-   - **Level 2**: Maker functions (90% of use cases)
-   - **Level 3**: Default instances (pre-built, exported)
-   - **Level 4**: Contracts (optional imports, advanced combinations)
-
-3. **Domain-Organized Architecture** (8 top-level domains):
-   - `lib` - Core library types
-   - `config` - Settings, defaults, workspace configuration
-   - `infrastructure` - Compute, storage, provisioning schemas
-   - `operations` - Workflows, batch, dependencies, tasks
-   - `deployment` - Kubernetes, execution modes
-   - `services` - Gitea and other platform services
-   - `generator` - Code generation and declarations
-   - `integrations` - Runtime, GitOps, external integrations
-
-4. **Two Deployment Modes**:
-   - **Development**: Fast iteration with relative imports (Single Source of Truth)
-   - **Production**: Frozen snapshots with immutable, self-contained deployment packages
-

-## Implementation Summary
-
-### Migration Complete
-
-| Metric | Value |
-| -------- | ------- |
-| KCL files migrated | 40 |
-| Nickel files created | 72 |
-| Modules converted | 24 core modules |
-| Schemas migrated | 150+ |
-| Maker functions | 80+ |
-| Default instances | 90+ |
-| JSON output validation | 4,680+ lines |
-
-### Platform Schemas (`provisioning/schemas/`)
-
-- **422 Nickel files** total
-- **8 domains** with hierarchical organization
-- **Entry point**: `main.ncl` with domain-organized architecture
-- **Clean imports**: `provisioning.lib`, `provisioning.config.settings`, etc.
-
-### Extensions (`provisioning/extensions/`)
-
-- **4 providers**: hetzner, local, aws, upcloud
-- **1 cluster type**: web
-- **Consistent structure**: Each extension has `nickel/` subdirectory with contracts, defaults, main, version
-
-**Example - UpCloud Provider**:
-
-```nickel
-# upcloud/nickel/main.ncl (migrated from upcloud/kcl/)
-let contracts = import "./contracts.ncl" in
-let defaults = import "./defaults.ncl" in
-
-{
-  defaults = defaults,
-  make_storage | not_exported = fun overrides =>
-    defaults.storage & overrides,
-  DefaultStorage = defaults.storage,
-  DefaultStorageBackup = defaults.storage_backup,
-  DefaultProvisionEnv = defaults.provision_env,
-  DefaultProvisionUpcloud = defaults.provision_upcloud,
-  DefaultServerDefaults_upcloud = defaults.server_defaults_upcloud,
-  DefaultServerUpcloud = defaults.server_upcloud,
-}
-```
-
-### Active Workspaces (`workspace_librecloud/nickel/`)
-
-- **47 Nickel files** in productive use
-- **2 infrastructures**:
-  - `wuji` - Kubernetes cluster with 20 taskservs
-  - `sgoyol` - Support servers group
-- **Two deployment modes** fully implemented and tested
-- **Daily production usage** validated ✅
-
-### Backward Compatibility
-
-- **955 KCL files** remain in workspaces/ (legacy user configs)
-- 100% backward compatible - old KCL code still works
-- Config loader supports both formats during transition
-- No breaking changes to APIs
-
----
-

-| -------- | ----- | -------- | -------- |
-| **Mental Model** | Python-like with schemas | JSON with functions | Nickel |
-| **Performance** | Baseline | 60% faster evaluation | Nickel |
-| **Type System** | Rigid schemas | Gradual typing + contracts | Nickel |
-| **Composition** | Schema inheritance | Record merging (`&`) | Nickel |
-| **Extensibility** | Requires schema modifications | Merging with custom fields | Nickel |

-## Architecture Patterns
-
-### Three-File Pattern
-
-**File 1: Contracts** (`batch_contracts.ncl`):
-
-```json
-{
-  BatchScheduler = {
-    strategy | String,
-    resource_limits,
-    scheduling_interval | Number,
-    enable_preemption | Bool,
-  },
-}
-```
-
-**File 2: Defaults** (`batch_defaults.ncl`):
-
-```json
-{
-  scheduler = {
-    strategy = "dependency_first",
-    resource_limits = {"max_cpu_cores" = 0},
-    scheduling_interval = 10,
-    enable_preemption = false,
-  },
-}
-```
-
-**File 3: Main** (`batch.ncl`):
-
-```javascript
-let contracts = import "./batch_contracts.ncl" in
-let defaults = import "./batch_defaults.ncl" in
-
-{
-  defaults = defaults,                    # Level 1: Inspection
-  make_scheduler | not_exported = fun o =>
-    defaults.scheduler & o,               # Level 2: Makers
-  DefaultScheduler = defaults.scheduler,  # Level 3: Instances
-}
-```
-
-### Hybrid Pattern Benefits
-
-- **90% of users**: Use makers for simple customization
-- **9% of users**: Reference defaults for inspection
-- **1% of users**: Access contracts for advanced combinations
-- **No validation conflicts**: Record merging works without contract constraints
-
-### Domain-Organized Architecture
-
-```nickel
-provisioning/schemas/
-├── lib/                  # Storage, TaskServDef, ClusterDef
-├── config/               # Settings, defaults, workspace_config
-├── infrastructure/       # Compute, storage, provisioning
-├── operations/           # Workflows, batch, dependencies, tasks
-├── deployment/           # Kubernetes, modes (solo, multiuser, cicd, enterprise)
-├── services/             # Gitea, etc
-├── generator/            # Declarations, gap analysis, changes
-├── integrations/         # Runtime, GitOps, main
-└── main.ncl              # Entry point with namespace organization
-```
-
-**Import pattern**:
-
-```javascript
-let provisioning = import "./main.ncl" in
-provisioning.lib              # For Storage, TaskServDef
-provisioning.config.settings  # For Settings, Defaults
-provisioning.infrastructure.compute.server
-provisioning.operations.workflows
-```

-
-## Production Deployment Patterns
-
-### Two-Mode Strategy
-
-#### 1. Development Mode (Single Source of Truth)
-
-- Relative imports to central provisioning
-- Fast iteration with immediate schema updates
-- No snapshot overhead
-- Usage: Local development, testing, experimentation
-
-```nickel
-# workspace_librecloud/nickel/main.ncl
-import "../../provisioning/schemas/main.ncl"
-import "../../provisioning/extensions/taskservs/kubernetes/nickel/main.ncl"
-```
-
-#### 2. Production Mode (Hermetic Deployment)
-
-Create immutable snapshots for reproducible deployments:
-
-```nickel
-provisioning workspace freeze --version "2025-12-15-prod-v1" --env production
-```
-
-**Frozen structure** (`.frozen/{version}/`):
-
-```nickel
-├── provisioning/schemas/    # Snapshot of central schemas
-├── extensions/              # Snapshot of all extensions
-└── workspace/               # Snapshot of workspace configs
-```
-
-**All imports rewritten to local paths**:
-
-- `import "../../provisioning/schemas/main.ncl"` → `import "./provisioning/schemas/main.ncl"`
-- Guarantees immutability and reproducibility
-- No external dependencies
-- Can be deployed to air-gapped environments
-
-**Deploy from frozen snapshot**:
-
-```nickel
-provisioning deploy --frozen "2025-12-15-prod-v1" --infra wuji
-```
-
-**Benefits**:
-
-- ✅ Development: Fast iteration with central updates
-- ✅ Production: Immutable, reproducible deployments
-- ✅ Audit trail: Each frozen version timestamped
-- ✅ Rollback: Easy rollback to previous versions
-- ✅ Air-gapped: Works in offline environments
-

-
-## Ecosystem Integration
-
-### TypeDialog (Bidirectional Nickel Integration)
-
-**Location**: `/Users/Akasha/Development/typedialog`
-**Purpose**: Type-safe prompts, forms, and schemas with Nickel output
-
-**Key Feature**: Nickel schemas → Type-safe UIs → Nickel output
-
-```nickel
-# Nickel schema → Interactive form
-typedialog form --schema server.ncl --output json
-
-# Interactive form → Nickel output
-typedialog form --input form.toml --output nickel
-```
-
-**Value**: Amplifies Nickel ecosystem beyond IaC:
-
-- Schemas auto-generate type-safe UIs
-- Forms output configurations back to Nickel
-- Multiple backends: CLI, TUI, Web
-- Multiple output formats: JSON, YAML, TOML, Nickel
-
----
-
-## Technical Patterns
-
-### Expression-Based Structure
-
-| KCL | Nickel |
-| ----- | -------- |
-| Multiple top-level let bindings | Single root expression with `let...in` chaining |
-
-### Schema Inheritance → Record Merging
-
-| KCL | Nickel |
-| ----- | -------- |
-| `schema Server(defaults.ServerDefaults)` | `defaults.ServerDefaults & { overrides }` |
-
-### Optional Fields
-
-| KCL | Nickel |
-| ----- | -------- |
-| `field?: type` | `field = null` or `field = ""` |
-
-### Union Types
-
-| KCL | Nickel |
-| ----- | -------- |
-| `"ubuntu" | "debian" | "centos"` | `[\\| 'ubuntu, 'debian, 'centos \\|]` |
-
-### Boolean/Null Conversion
-
-| KCL | Nickel |
-| ----- | -------- |
-| `True` / `False` / `None` | `true` / `false` / `null` |

-# ADR-014: Nushell Nickel Plugin - CLI Wrapper Architecture
-
-## Status
-
-**Accepted** - 2025-12-15
-
-## Context
-
-The provisioning system integrates with Nickel for configuration management in advanced
-scenarios. Users need to evaluate Nickel files and work with their output in Nushell
-scripts. The `nu_plugin_nickel` plugin provides this integration.
-
-The architectural decision was whether the plugin should:
-
-1. **Implement Nickel directly using pure Rust** (`nickel-lang-core` crate)
-2. **Wrap the official Nickel CLI** (`nickel` command)
-
-### System Requirements
-
-Nickel configurations in provisioning use the **module system**:
-
-```nickel
-# config/database.ncl
-import "lib/defaults" as defaults
-import "lib/validation" as valid
-
-{
-  databases: {
-    primary = defaults.database & {
-      name = "primary"
-      host = "localhost"
-    }
-  }
-}
-```
-
-Module system includes:
-
-- Import resolution with search paths
-- Standard library (`builtins`, stdlib packages)
-- Module caching
-- Complex evaluation context
-
-## Decision
-
-Implement the `nu_plugin_nickel` plugin as a **CLI wrapper** that invokes the external `nickel` command.
-

-### Implementation Characteristics
-
-**Plugin provides**:
-
-- ✅ Nushell commands: `nickel-export`, `nickel-eval`, `nickel-format`, `nickel-validate`
-- ✅ JSON/YAML output parsing (serde_json → nu_protocol::Value)
-- ✅ Automatic caching (SHA256-based, ~80-90% hit rate)
-- ✅ Error handling (CLI errors → Nushell errors)
-- ✅ Type-safe output (nu_protocol::Value::Record, not strings)
-
-**Plugin delegates to Nickel CLI**:
-
-- ✅ Module resolution with search paths
-- ✅ Standard library access and discovery
-- ✅ Evaluation context setup
-- ✅ Module caching
-- ✅ Output formatting
-
-## Rationale
-
-### Why CLI Wrapper Is The Correct Choice
-
-| Aspect | Pure Rust (nickel-lang-core) | CLI Wrapper (chosen) |
-| -------- | ------------------------------- | ---------------------- |
-| **Module resolution** | ❓ Undocumented API | ✅ Official, proven |
-| **Search paths** | ❓ How to configure? | ✅ CLI handles it |
-| **Standard library** | ❓ How to access? | ✅ Automatic discovery |
-| **Import system** | ❌ API unclear | ✅ Built-in |
-| **Evaluation context** | ❌ Complex setup needed | ✅ CLI provides |
-| **Future versions** | ⚠️ Maintain parity | ✅ Automatic support |
-| **Maintenance burden** | 🔴 High | 🟢 Low |
-| **Complexity** | 🔴 High | 🟢 Low |
-| **Correctness** | ⚠️ Risk of divergence | ✅ Single source of truth |
-
-### The Module System Problem
-
-Using `nickel-lang-core` directly would require the plugin to:
-
-1. **Configure import search paths**:
-
-   ```rust
-   // Where should Nickel look for modules?
-   // Current directory? Workspace? System paths?
-   // This is complex and configuration-dependent
-   ```
-
-1. **Access standard library**:
-
-   ```rust
-   // Where is the Nickel stdlib installed?
-   // How to handle different Nickel versions?
-   // How to provide builtins?
-   ```
-
-2. **Manage module evaluation context**:
-
-   ```rust
-   // Set up evaluation environment
-   // Configure cache locations
-   // Initialize type checker
-   // This is essentially re-implementing CLI logic
-   ```
-
-3. **Maintain compatibility**:
-   - Every Nickel version change requires review
-   - Risk of subtle behavioral differences
-   - Duplicate bug fixes and features
-   - Two implementations to maintain
-
-### Documentation Gap
-
-The `nickel-lang-core` crate lacks clear documentation on:
-
-- ❓ How to configure import search paths
-- ❓ How to access standard library
-- ❓ How to set up evaluation context
-- ❓ What is the public API contract?
-
-This makes direct usage risky. The CLI is the documented, proven interface.
-
-### Why Nickel Is Different From Simple Use Cases
-
-**Simple use case** (direct library usage works):
-
-- Simple evaluation with built-in functions
-- No external dependencies
-- No modules or imports
-
-**Nickel reality** (CLI wrapper necessary):
-
-- Complex module system with search paths
-- External dependencies (standard library)
-- Import resolution with multiple fallbacks
-- Evaluation context that mirrors CLI
-
-## Consequences
-
-### Positive
-
-- **Correctness**: Module resolution guaranteed by official Nickel CLI
-- **Reliability**: No risk from reverse-engineering undocumented APIs
-- **Simplicity**: Plugin code is lean (~300 lines total)
-- **Maintainability**: Automatic tracking of Nickel changes
-- **Compatibility**: Works with all Nickel versions
-- **User Expectations**: Same behavior as CLI users experience
-- **Community Alignment**: Uses official Nickel distribution
-
-### Negative
-
-- **External Dependency**: Requires `nickel` binary installed in PATH
-- **Process Overhead**: ~100-200 ms per execution (heavily cached)
-- **Subprocess Management**: Spawn handling and stderr capture needed
-- **Distribution**: Provisioning must include Nickel binary
-
-### Mitigation Strategies
-
-**Dependency Management**:
-
-- Installation scripts handle Nickel setup
-- Docker images pre-install Nickel
-- Clear error messages if `nickel` not found
-- Documentation covers installation
-
-**Performance**:
-
-- Aggressive caching (80-90% typical hit rate)
-- Cache hits: ~1-5 ms (not 100-200 ms)
-- Cache directory: `~/.cache/provisioning/config-cache/`
-
-**Distribution**:
-
-- Provisioning distributions include Nickel
-- Installers set up Nickel automatically
-- CI/CD has Nickel available
-
-## Alternatives Considered
-
-### Alternative 1: Pure Rust with nickel-lang-core
-
-**Pros**: No external dependency
-**Cons**: Undocumented API, high risk, maintenance burden
-**Decision**: REJECTED - Too risky
-
-### Alternative 2: Hybrid (Pure Rust + CLI fallback)
-
-**Pros**: Flexibility
-**Cons**: Adds complexity, dual code paths, confusing behavior
-**Decision**: REJECTED - Over-engineering
-
-### Alternative 3: WebAssembly Version
-
-**Pros**: Standalone
-**Cons**: WASM support unclear, additional infrastructure
-**Decision**: REJECTED - Immature
-
-### Alternative 4: Use Nickel LSP
-
-**Pros**: Uses official interface
-**Cons**: LSP not designed for evaluation, wrong abstraction
-**Decision**: REJECTED - Inappropriate tool
-
-## Implementation Details
-
-### Command Set
-
-1. **nickel-export**: Export/evaluate Nickel file
-
-   ```nushell
-   nickel-export json /path/to/file.ncl
-   nickel-export yaml /path/to/file.ncl
-   ```
-
-2. **nickel-eval**: Evaluate with automatic caching (for config loader)
-
-   ```nushell
-   nickel-eval /workspace/config.ncl
-   ```
-
-3. **nickel-format**: Format Nickel files
-
-   ```nushell
-   nickel-format /path/to/file.ncl
-   ```
-
-4. **nickel-validate**: Validate Nickel files/project
-
-   ```nushell
-   nickel-validate /path/to/project
-   ```
-
-### Critical Implementation Detail: Command Syntax
-
-The plugin uses the **correct Nickel command syntax**:
-
-```nickel
-// Correct:
-cmd.arg("export").arg(file).arg("--format").arg(format);
-// Results in: "nickel export /file --format json"
-
-// WRONG (previously):
-cmd.arg("export").arg(format).arg(file);
-// Results in: "nickel export json /file"
-// ↑ This triggers auto-import of nonexistent JSON module
-```
-
-### Caching Strategy
-
-**Cache Key**: SHA256(file_content + format)
-**Cache Hit Rate**: 80-90% (typical provisioning workflows)
-**Performance**:
-
-- Cache miss: ~100-200 ms (process fork)
-- Cache hit: ~1-5 ms (filesystem read + parse)
-- Speedup: 50-100x for cached runs
-
-**Storage**: `~/.cache/provisioning/config-cache/`
-
-### JSON Output Processing
-
-Plugin correctly processes JSON output:
-
-1. Invokes: `nickel export /file.ncl --format json`
-2. Receives: JSON string from stdout
-3. Parses: serde_json::Value
-4. Converts: `json_value_to_nu_value()` (recursive)
-5. Returns: nu_protocol::Value::Record (not string!)
-
-This enables Nushell cell path access:
-
-```nushell
-nickel-export json /config.ncl | .database.host  # ✅ Works
-```
-
-## Testing Strategy
-
-**Unit Tests**:
-
-- JSON parsing correctness
-- Value type conversions
-- Cache logic
-
-**Integration Tests**:
-
-- Real Nickel file execution
-- Module imports verification
-- Search path resolution
-
-**Manual Verification**:
-
-```nickel
-# Test module imports
-nickel-export json /workspace/config.ncl
-
-# Test cell path access
-nickel-export json /workspace/config.ncl | .database
-
-# Verify output types
-nickel-export json /workspace/config.ncl | type
-# Should show: record, not string
-```
-
-## Configuration Integration
-
-Plugin integrates with provisioning config system:
-
-- Nickel path auto-detected: `which nickel`
-- Cache location: platform-specific `cache_dir()`
-- Errors: consistent with provisioning patterns

-# ADR-013: Typdialog Web UI Backend Integration for Interactive Configuration
-
-## Status
-
-**Accepted** - 2025-01-08
-
-## Context
-
-The provisioning system requires interactive user input for configuration workflows, workspace initialization, credential setup, and guided deployment
-scenarios. The system architecture combines Rust (performance-critical), Nushell (scripting), and Nickel (declarative configuration), creating
-challenges for interactive form-based input and multi-user collaboration.
-
-### The Interactive Configuration Problem
-
-**Current limitations**:
-
-1. **Nushell CLI**: Terminal-only interaction
-   - `input` command: Single-line text prompts only
-   - No form validation, no complex multi-field forms
-   - Limited to single-user, terminal-bound workflows
-   - User experience: Basic and error-prone
-
-2. **Nickel**: Declarative configuration language
-   - Cannot handle interactive prompts (by design)
-   - Pure evaluation model (no side effects)
-   - Forms must be defined statically, not interactively
-   - No runtime user interaction
-
-3. **Existing Solutions**: Inadequate for modern infrastructure provisioning
-   - **Shell-based prompts**: Error-prone, no validation, single-user
-   - **Custom web forms**: High maintenance, inconsistent UX
-   - **Separate admin panels**: Disconnected from IaC workflow
-   - **Terminal-only TUI**: Limited to SSH sessions, no collaboration
-
-### Use Cases Requiring Interactive Input
-
-1. **Workspace Initialization**:
-   ```nushell
-   # Current: Error-prone prompts
-   let workspace_name = input "Workspace name: "
-   let provider = input "Provider (aws/azure/oci): "
-   # No validation, no autocomplete, no guidance
-   ```
-
-2. **Credential Setup**:
-   ```nushell
-   # Current: Insecure and basic
-   let api_key = input "API Key: "  # Shows in terminal history
-   let region = input "Region: "    # No validation
-   ```
-
-3. **Configuration Wizards**:
-   - Database connection setup (host, port, credentials, SSL)
-   - Network configuration (CIDR blocks, subnets, gateways)
-   - Security policies (encryption, access control, audit)
-
-4. **Guided Deployments**:
-   - Multi-step infrastructure provisioning
-   - Service selection with dependencies
-   - Environment-specific overrides
-
-### Requirements for Interactive Input System
-
-- ✅ **Terminal UI widgets**: Text input, password, select, multi-select, confirm
-- ✅ **Validation**: Type checking, regex patterns, custom validators
-- ✅ **Security**: Password masking, sensitive data handling
-- ✅ **User Experience**: Arrow key navigation, autocomplete, help text
-- ✅ **Composability**: Chain multiple prompts into forms
-- ✅ **Error Handling**: Clear validation errors, retry logic
-- ✅ **Rust Integration**: Native Rust library (no subprocess overhead)
-- ✅ **Cross-Platform**: Works on Linux, macOS, Windows
-
-## Decision
-
-Integrate **typdialog** with its **Web UI backend** as the standard interactive configuration interface for the provisioning platform. The major
-achievement of typdialog is not the TUI - it is the Web UI backend that enables browser-based forms, multi-user collaboration, and seamless
-integration with the provisioning orchestrator.

-### Implementation Characteristics
-
-**CLI Integration Provides**:
-
-- ✅ Native Rust commands with TUI dialogs
-- ✅ Form-based input for complex configurations
-- ✅ Validation rules defined in Rust (type-safe)
-- ✅ Secure input (password masking, no history)
-- ✅ Error handling with retry logic
-- ✅ Serialization to Nickel/TOML/JSON
-
-**TUI Dialog Library Handles**:
-
-- ✅ Terminal UI rendering and event loop
-- ✅ Widget management (text, select, checkbox, confirm)
-- ✅ Input validation and error display
-- ✅ Navigation (arrow keys, tab, enter)
-- ✅ Cross-platform terminal compatibility
-
-## Rationale
-
-### Why TUI Dialog Integration Is Required
-
-| Aspect | Shell Prompts (current) | Web Forms | TUI Dialog (chosen) |
-| -------- | ------------------------- | ----------- | --------------------- |
-| **User Experience** | ❌ Basic text only | ✅ Rich UI | ✅ Rich TUI |
-| **Validation** | ❌ Manual, error-prone | ✅ Built-in | ✅ Built-in |
-| **Security** | ❌ Plain text, history | ⚠️ Network risk | ✅ Secure terminal |
-| **Setup Complexity** | ✅ None | ❌ Server required | ✅ Minimal |
-| **Terminal Workflow** | ✅ Native | ❌ Browser switch | ✅ Native |
-| **Offline Support** | ✅ Always | ❌ Requires server | ✅ Always |
-| **Dependencies** | ✅ None | ❌ Web stack | ✅ Single crate |
-| **Error Handling** | ❌ Manual | ⚠️ Complex | ✅ Built-in retry |
-
-### The Nushell Limitation
-
-Nushell's `input` command is limited:
-
-```nushell
-# Current: No validation, no security
-let password = input "Password: "  # ❌ Shows in terminal
-let region = input "AWS Region: "   # ❌ No autocomplete/validation
-
-# Cannot do:
-# - Multi-select from options
-# - Conditional fields (if X then ask Y)
-# - Password masking
-# - Real-time validation
-# - Autocomplete/fuzzy search
-```
-
-### The Nickel Constraint
-
-Nickel is declarative and cannot prompt users:
-
-```nickel
-# Nickel defines what the config looks like, NOT how to get it
-{
-  database = {
-    host | String,
-    port | Number,
-    credentials | { username: String, password: String },
-  }
-}
-
-# Nickel cannot:
-# - Prompt user for values
-# - Show interactive forms
-# - Validate input interactively
-```
-
-### Why Rust + TUI Dialog Is The Solution
-
-**Rust provides**:
-- Native terminal control (crossterm, termion)
-- Type-safe form definitions
-- Validation rules as functions
-- Secure memory handling (password zeroization)
-- Performance (no subprocess overhead)
-
-**TUI Dialog provides**:
-- Widget library (text, select, multi-select, confirm)
-- Event loop and rendering
-- Validation framework
-- Error display and retry logic
-
-**Integration enables**:
-- Nushell calls Rust CLI → Shows TUI dialog → Returns validated config
-- Nickel receives validated config → Type checks → Merges with defaults
-
-## Consequences
-
-### Positive
-
-- **User Experience**: Professional TUI with validation and guidance
-- **Security**: Password masking, sensitive data protection, no terminal history
-- **Validation**: Type-safe rules enforced before config generation
-- **Developer Experience**: Reusable form components across CLI commands
-- **Error Handling**: Clear validation errors with retry options
-- **Offline First**: No network dependencies for interactive input
-- **Terminal Native**: Fits CLI workflow, no context switching
-- **Maintainability**: Single library for all interactive input
-
-### Negative
-
-- **Terminal Dependency**: Requires interactive terminal (not scriptable)
-- **Learning Curve**: Developers must learn TUI dialog patterns
-- **Library Lock-in**: Tied to specific TUI library API
-- **Testing Complexity**: Interactive tests require terminal mocking
-- **Non-Interactive Fallback**: Need alternative for CI/CD and scripts
-
-### Mitigation Strategies
-
-**Non-Interactive Mode**:
-```bash
-// Support both interactive and non-interactive
-if terminal::is_interactive() {
-    // Show TUI dialog
-    let config = show_workspace_form()?;
-} else {
-    // Use config file or CLI args
-    let config = load_config_from_file(args.config)?;
-}
-```
-
-**Testing**:
-```bash
-// Unit tests: Test form validation logic (no TUI)
-#[test]
-fn test_validate_workspace_name() {
-    assert!(validate_name("my-workspace").is_ok());
-    assert!(validate_name("invalid name!").is_err());
-}
-
-// Integration tests: Use mock terminal or config files
-```
-
-**Scriptability**:
-```bash
-# Batch mode: Provide config via file
-provisioning workspace init --config workspace.toml
-
-# Interactive mode: Show TUI dialog
-provisioning workspace init --interactive
-```
-
-**Documentation**:
-- Form schemas documented in `docs/`
-- Config file examples provided
-- Screenshots of TUI forms in guides
-
-## Alternatives Considered
-
-### Alternative 1: Shell-Based Prompts (Current State)
-
-**Pros**: Simple, no dependencies
-**Cons**: No validation, poor UX, security risks
-**Decision**: REJECTED - Inadequate for production use
-
-### Alternative 2: Web-Based Forms
-
-**Pros**: Rich UI, well-known patterns
-**Cons**: Requires server, network dependency, context switch
-**Decision**: REJECTED - Too complex for CLI tool
-
-### Alternative 3: Custom TUI Per Use Case
-
-**Pros**: Tailored to each need
-**Cons**: High maintenance, code duplication, inconsistent UX
-**Decision**: REJECTED - Not sustainable
-
-### Alternative 4: External Form Tool (dialog, whiptail)
-
-**Pros**: Mature, cross-platform
-**Cons**: Subprocess overhead, limited validation, shell escaping issues
-**Decision**: REJECTED - Poor Rust integration
-
-### Alternative 5: Text-Based Config Files Only
-
-**Pros**: Fully scriptable, no interactive complexity
-**Cons**: Steep learning curve, no guidance for new users
-**Decision**: REJECTED - Poor user onboarding experience
-
-## Implementation Details
-
-### Form Definition Pattern
-
-```bash
-use typdialog::Form;
-
-pub fn workspace_initialization_form() -> Result<WorkspaceConfig> {
-    let form = Form::new("Workspace Initialization")
-        .add_text_input("name", "Workspace Name")
-            .required()
-            .validator(|s| validate_workspace_name(s))
-        .add_select("provider", "Cloud Provider")
-            .options(&["aws", "azure", "oci", "local"])
-            .required()
-        .add_text_input("region", "Region")
-            .default("us-west-2")
-            .validator(|s| validate_region(s))
-        .add_password("admin_password", "Admin Password")
-            .required()
-            .min_length(12)
-        .add_confirm("enable_monitoring", "Enable Monitoring?")
-            .default(true);
-
-    let responses = form.run()?;
-
-    // Convert to strongly-typed config
-    let config = WorkspaceConfig {
-        name: responses.get_string("name")?,
-        provider: responses.get_string("provider")?.parse()?,
-        region: responses.get_string("region")?,
-        admin_password: responses.get_password("admin_password")?,
-        enable_monitoring: responses.get_bool("enable_monitoring")?,
-    };
-
-    Ok(config)
-}
-```
-
-### Integration with Nickel
-
-```nickel
-// 1. Get validated input from TUI dialog
-let config = workspace_initialization_form()?;
-
-// 2. Serialize to TOML/JSON
-let config_toml = toml::to_string(&config)?;
-
-// 3. Write to workspace config
-fs::write("workspace/config.toml", config_toml)?;
-
-// 4. Nickel merges with defaults
-// nickel export workspace/main.ncl --format json
-// (uses workspace/config.toml as input)
-```
-
-### CLI Command Structure
-
-```bash
-// provisioning/core/cli/src/commands/workspace.rs
-
-#[derive(Parser)]
-pub enum WorkspaceCommand {
-    Init {
-        #[arg(long)]
-        interactive: bool,
-
-        #[arg(long)]
-        config: Option<PathBuf>,
-    },
-}
-
-pub fn handle_workspace_init(args: InitArgs) -> Result<()> {
-    if args.interactive || terminal::is_interactive() {
-        // Show TUI dialog
-        let config = workspace_initialization_form()?;
-        config.save("workspace/config.toml")?;
-    } else if let Some(config_path) = args.config {
-        // Use provided config
-        let config = WorkspaceConfig::load(config_path)?;
-        config.save("workspace/config.toml")?;
-    } else {
-        bail!("Either --interactive or --config required");
-    }
-
-    // Continue with workspace setup
-    Ok(())
-}
-```
-
-### Validation Rules
-
-```rust
-pub fn validate_workspace_name(name: &str) -> Result<(), String> {
-    // Alphanumeric, hyphens, 3-32 chars
-    let re = Regex::new(r"^[a-z0-9-]{3,32}$").unwrap();
-    if !re.is_match(name) {
-        return Err("Name must be 3-32 lowercase alphanumeric chars with hyphens".into());
-    }
-    Ok(())
-}
-
-pub fn validate_region(region: &str) -> Result<(), String> {
-    const VALID_REGIONS: &[&str] = &["us-west-1", "us-west-2", "us-east-1", "eu-west-1"];
-    if !VALID_REGIONS.contains(&region) {
-        return Err(format!("Invalid region. Must be one of: {}", VALID_REGIONS.join(", ")));
-    }
-    Ok(())
-}
-```
-
-### Security: Password Handling
-
-```bash
-use zeroize::Zeroizing;
-
-pub fn get_secure_password() -> Result<Zeroizing<String>> {
-    let form = Form::new("Secure Input")
-        .add_password("password", "Password")
-            .required()
-            .min_length(12)
-            .validator(password_strength_check);
-
-    let responses = form.run()?;
-
-    // Password automatically zeroized when dropped
-    let password = Zeroizing::new(responses.get_password("password")?);
-
-    Ok(password)
-}
-```
-
-## Testing Strategy
-
-**Unit Tests**:
-```bash
-#[test]
-fn test_workspace_name_validation() {
-    assert!(validate_workspace_name("my-workspace").is_ok());
-    assert!(validate_workspace_name("UPPERCASE").is_err());
-    assert!(validate_workspace_name("ab").is_err()); // Too short
-}
-```
-
-**Integration Tests**:
-```bash
-// Use non-interactive mode with config files
-#[test]
-fn test_workspace_init_non_interactive() {
-    let config = WorkspaceConfig {
-        name: "test-workspace".into(),
-        provider: Provider::Local,
-        region: "us-west-2".into(),
-        admin_password: "secure-password-123".into(),
-        enable_monitoring: true,
-    };
-
-    config.save("/tmp/test-config.toml").unwrap();
-
-    let result = handle_workspace_init(InitArgs {
-        interactive: false,
-        config: Some("/tmp/test-config.toml".into()),
-    });
-
-    assert!(result.is_ok());
-}
-```
-
-**Manual Testing**:
-```bash
-# Test interactive flow
-cargo build --release
-./target/release/provisioning workspace init --interactive
-
-# Test validation errors
-# - Try invalid workspace name
-# - Try weak password
-# - Try invalid region
-```
-
-## Configuration Integration
-
-**CLI Flag**:
-```toml
-# provisioning/config/config.defaults.toml
-[ui]
-interactive_mode = "auto"  # "auto" | "always" | "never"
-dialog_theme = "default"   # "default" | "minimal" | "colorful"
-```
-
-**Environment Override**:
-```bash
-# Force non-interactive mode (for CI/CD)
-export PROVISIONING_INTERACTIVE=false
-
-# Force interactive mode
-export PROVISIONING_INTERACTIVE=true
-```

-# ADR-014: SecretumVault Integration for Secrets Management
-
-## Status
-
-**Accepted** - 2025-01-08
-
-## Context
-
-The provisioning system manages sensitive data across multiple infrastructure layers: cloud provider credentials, database passwords, API keys, SSH
-keys, encryption keys, and service tokens. The current security architecture (ADR-009) includes SOPS for encrypted config files and Age for key
-management, but lacks a centralized secrets management solution with dynamic secrets, access control, and audit logging.
-
-### Current Secrets Management Challenges
-
-**Existing Approach**:
-
-1. **SOPS + Age**: Static secrets encrypted in config files
-   - Good: Version-controlled, gitops-friendly
-   - Limited: Static rotation, no audit trail, manual key distribution
-
-2. **Nickel Configuration**: Declarative secrets references
-   - Good: Type-safe configuration
-   - Limited: Cannot generate dynamic secrets, no lifecycle management
-
-3. **Manual Secret Injection**: Environment variables, CLI flags
-   - Good: Simple for development
-   - Limited: No security guarantees, prone to leakage
-
-### Problems Without Centralized Secrets Management
-
-**Security Issues**:
-- ❌ No centralized audit trail (who accessed which secret when)
-- ❌ No automatic secret rotation policies
-- ❌ No fine-grained access control (Cedar policies not enforced on secrets)
-- ❌ Secrets scattered across: SOPS files, env vars, config files, K8s secrets
-- ❌ No detection of secret sprawl or leaked credentials
-
-**Operational Issues**:
-- ❌ Manual secret rotation (error-prone, often neglected)
-- ❌ No secret versioning (cannot rollback to previous credentials)
-- ❌ Difficult onboarding (manual key distribution)
-- ❌ No dynamic secrets (credentials exist indefinitely)
-
-**Compliance Issues**:
-- ❌ Cannot prove compliance with secret access policies
-- ❌ No audit logs for regulatory requirements
-- ❌ Cannot enforce secret expiration policies
-- ❌ Difficult to demonstrate least-privilege access
-
-### Use Cases Requiring Centralized Secrets Management
-
-1. **Dynamic Database Credentials**:
-   - Generate short-lived DB credentials for applications
-   - Automatic rotation based on policies
-   - Revocation on application termination
-
-2. **Cloud Provider API Keys**:
-   - Centralized storage with access control
-   - Audit trail of credential usage
-   - Automatic rotation schedules
-
-3. **Service-to-Service Authentication**:
-   - Dynamic tokens for microservices
-   - Short-lived certificates for mTLS
-   - Automatic renewal before expiration
-
-4. **SSH Key Management**:
-   - Temporal SSH keys (ADR-009 SSH integration)
-   - Centralized certificate authority
-   - Audit trail of SSH access
-
-5. **Encryption Key Management**:
-   - Master encryption keys for data at rest
-   - Key rotation and versioning
-   - Integration with KMS systems
-
-### Requirements for Secrets Management System
-
-- ✅ **Dynamic Secrets**: Generate credentials on-demand with TTL
-- ✅ **Access Control**: Integration with Cedar authorization policies
-- ✅ **Audit Logging**: Complete trail of secret access and modifications
-- ✅ **Secret Rotation**: Automatic and manual rotation policies
-- ✅ **Versioning**: Track secret versions, enable rollback
-- ✅ **High Availability**: Distributed, fault-tolerant architecture
-- ✅ **Encryption at Rest**: AES-256-GCM for stored secrets
-- ✅ **API-First**: RESTful API for integration
-- ✅ **Plugin Ecosystem**: Extensible backends (AWS, Azure, databases)
-- ✅ **Open Source**: Self-hosted, no vendor lock-in
-
-## Decision
-
-Integrate **SecretumVault** as the centralized secrets management system for the provisioning platform.

-## Rationale
-
-### Why SecretumVault Is Required
-
-| Aspect | SOPS + Age (current) | HashiCorp Vault | SecretumVault (chosen) |
-| -------- | ---------------------- | ----------------- | ------------------------ |
-| **Dynamic Secrets** | ❌ Static only | ✅ Full support | ✅ Full support |
-| **Rust Native** | ⚠️ External CLI | ❌ Go binary | ✅ Pure Rust |
-| **Cedar Integration** | ❌ None | ❌ Custom policies | ✅ Native Cedar |
-| **Audit Trail** | ❌ Git only | ✅ Comprehensive | ✅ Comprehensive |
-| **Secret Rotation** | ❌ Manual | ✅ Automatic | ✅ Automatic |
-| **Open Source** | ✅ Yes | ⚠️ MPL 2.0 (BSL now) | ✅ Yes |
-| **Self-Hosted** | ✅ Yes | ✅ Yes | ✅ Yes |
-| **License** | ✅ Permissive | ⚠️ BSL (proprietary) | ✅ Permissive |
-| **Versioning** | ⚠️ Git commits | ✅ Built-in | ✅ Built-in |
-| **High Availability** | ❌ Single file | ✅ Raft cluster | ✅ Raft cluster |
-| **Performance** | ✅ Fast (local) | ⚠️ Network latency | ✅ Rust performance |
-
-### Why Not Continue with SOPS Alone
-
-SOPS is excellent for **static secrets in git**, but inadequate for:
-
-1. **Dynamic Credentials**: Cannot generate temporary DB passwords
-2. **Audit Trail**: Git commits are insufficient for compliance
-3. **Rotation Policies**: Manual rotation is error-prone
-4. **Access Control**: No runtime policy enforcement
-5. **Secret Lifecycle**: Cannot track usage or revoke access
-6. **Multi-System Integration**: Limited to files, not API-accessible
-
-**Complementary Approach**:
-- SOPS: Configuration files with long-lived secrets (gitops workflow)
-- SecretumVault: Runtime dynamic secrets, short-lived credentials, audit trail
-
-### Why SecretumVault Over HashiCorp Vault
-
-**HashiCorp Vault Limitations**:
-
-1. **License Change**: BSL (Business Source License) - proprietary for production
-2. **Not Rust Native**: Go binary, subprocess overhead
-3. **Custom Policy Language**: HCL policies, not Cedar (provisioning standard)
-4. **Complex Deployment**: Heavy operational burden
-5. **Vendor Lock-In**: HashiCorp ecosystem dependency
-
-**SecretumVault Advantages**:
-
-1. **Rust Native**: Zero-cost integration, no subprocess spawning
-2. **Cedar Policies**: Consistent with ADR-008 authorization model
-3. **Lightweight**: Smaller binary, lower resource usage
-4. **Open Source**: Permissive license, community-driven
-5. **Provisioning-First**: Designed for IaC workflows
-
-### Integration with Existing Security Architecture
-
-**ADR-009 (Security System)**:
-- SOPS: Static config encryption (unchanged)
-- Age: Key management for SOPS (unchanged)
-- SecretumVault: Dynamic secrets, runtime access control (new)
-
-**ADR-008 (Cedar Authorization)**:
-- Cedar policies control SecretumVault secret access
-- Fine-grained permissions: `read:secret:database/prod/password`
-- Audit trail records Cedar policy decisions
-
-**SSH Temporal Keys**:
-- SecretumVault SSH CA signs user certificates
-- Short-lived certificates (1-24 hours)
-- Audit trail of SSH access
-
-## Consequences
-
-### Positive
-
-- **Security Posture**: Centralized secrets with audit trail and rotation
-- **Compliance**: Complete audit logs for regulatory requirements
-- **Operational Excellence**: Automatic rotation, dynamic credentials
-- **Developer Experience**: Simple API for secret access
-- **Performance**: Rust implementation, zero-cost abstractions
-- **Consistency**: Cedar policies across entire system (auth + secrets)
-- **Observability**: Metrics, logs, traces for secret access
-- **Disaster Recovery**: Secret versioning enables rollback
-
-### Negative
-
-- **Infrastructure Complexity**: Additional service to deploy and operate
-- **High Availability Requirements**: Raft cluster needs 3+ nodes
-- **Migration Effort**: Existing SOPS secrets need migration path
-- **Learning Curve**: Operators must learn vault concepts
-- **Dependency Risk**: Critical path service (secrets unavailable = system down)
-
-### Mitigation Strategies
-
-**High Availability**:
-```bash
-# Deploy SecretumVault cluster (3 nodes)
-provisioning deploy secretum-vault --ha --replicas 3
-
-# Automatic leader election via Raft
-# Clients auto-reconnect to leader
-```
-
-**Migration from SOPS**:
-```bash
-# Phase 1: Import existing SOPS secrets into SecretumVault
-provisioning secrets migrate --from-sops config/secrets.yaml
-
-# Phase 2: Update Nickel configs to reference vault paths
-# Phase 3: Deprecate SOPS for runtime secrets (keep for config files)
-```
-
-**Fallback Strategy**:
-```bash
-// Graceful degradation if vault unavailable
-let secret = match vault_client.get_secret("database/password").await {
-    Ok(s) => s,
-    Err(VaultError::Unavailable) => {
-        // Fallback to SOPS for read-only operations
-        warn!("Vault unavailable, using SOPS fallback");
-        sops_decrypt("config/secrets.yaml", "database.password")?
-    },
-    Err(e) => return Err(e),
-};
-```
-
-**Operational Monitoring**:
-```bash
-# prometheus metrics
-secretum_vault_request_duration_seconds
-secretum_vault_secret_lease_expiry
-secretum_vault_auth_failures_total
-secretum_vault_raft_leader_changes
-
-# Alerts: Vault unavailable, high auth failure rate, lease expiry
-```
-
-## Alternatives Considered
-
-### Alternative 1: Continue with SOPS Only
-
-**Pros**: No new infrastructure, simple
-**Cons**: No dynamic secrets, no audit trail, manual rotation
-**Decision**: REJECTED - Insufficient for production security
-
-### Alternative 2: HashiCorp Vault
-
-**Pros**: Mature, feature-rich, widely adopted
-**Cons**: BSL license, Go binary, HCL policies (not Cedar), complex deployment
-**Decision**: REJECTED - License and integration concerns
-
-### Alternative 3: Cloud Provider Native (AWS Secrets Manager, Azure Key Vault)
-
-**Pros**: Fully managed, high availability
-**Cons**: Vendor lock-in, multi-cloud complexity, cost at scale
-**Decision**: REJECTED - Against open-source and multi-cloud principles
-
-### Alternative 4: CyberArk, 1Password, and Others
-
-**Pros**: Enterprise features
-**Cons**: Proprietary, expensive, poor API integration
-**Decision**: REJECTED - Not suitable for IaC automation
-
-### Alternative 5: Build Custom Secrets Manager
-
-**Pros**: Full control, tailored to needs
-**Cons**: High maintenance burden, security risk, reinventing wheel
-**Decision**: REJECTED - SecretumVault provides this already
-
-## Implementation Details
-
-### SecretumVault Deployment
-
-```bash
-# Deploy via provisioning system
-provisioning deploy secretum-vault 
-  --ha 
-  --replicas 3 
-  --storage postgres 
-  --tls-cert /path/to/cert.pem 
-  --tls-key /path/to/key.pem
-
-# Initialize and unseal
-provisioning vault init

-```
-
-### Rust Client Library
-
-```rust
-// provisioning/core/libs/secretum-client/src/lib.rs
-
-use secretum_vault::{Client, SecretEngine, Auth};
-
-pub struct VaultClient {
-    client: Client,
-}
-
-impl VaultClient {
-    pub async fn new(addr: &str, token: &str) -> Result<Self> {
-        let client = Client::new(addr)
-            .auth(Auth::Token(token))

-
-    pub async fn sign_ssh_key(&self, public_key: &str, ttl: Duration) -> Result<Certificate> {
-        self.client.ssh().sign_key(public_key, ttl).await
-    }
-}
-```
-
-### Nushell Integration
-
-```nushell
-# Nushell commands via Rust CLI wrapper
-provisioning secrets get database/prod/password
-provisioning secrets set api/keys/stripe --value "sk_live_xyz"
-provisioning secrets rotate database/prod/password
-provisioning secrets lease renew lease_id_12345
-provisioning secrets list database/
-```
-
-### Nickel Configuration Integration
-
-```nickel
-# provisioning/schemas/database.ncl
-{
-  database = {
-    host = "postgres.example.com",
-    port = 5432,
-    username = secrets.get "database/prod/username",
-    password = secrets.get "database/prod/password",
-  }
-}
-
-# Nickel function: secrets.get resolves to SecretumVault API call
-```
-
-### Cedar Policy for Secret Access
-
-```bash
-// policy: developers can read dev secrets, not prod
-permit(
-  principal in Group::"developers",
-  action == Action::"read",
-  resource in Secret::"database/dev"
-);
-
-forbid(
-  principal in Group::"developers",
-  action == Action::"read",
-  resource in Secret::"database/prod"
-);
-
-// policy: CI/CD can generate dynamic DB credentials
-permit(
-  principal == Service::"github-actions",
-  action == Action::"generate",
-  resource in Secret::"database/dynamic"
-) when {
-  context.ttl <= duration("1h")
-};
-```
-
-### Dynamic Database Credentials
-
-```bash
-// Application requests temporary DB credentials
-let creds = vault_client
-    .database()
-    .generate_credentials("postgres-readonly")
-    .await?;
-
-println!("Username: {}", creds.username); // v-app-abcd1234
-println!("Password: {}", creds.password); // random-secure-password
-println!("TTL: {}", creds.lease_duration);  // 1h
-
-// Credentials automatically revoked after TTL
-// No manual cleanup needed
-```
-
-### Secret Rotation Automation
-
-```bash
-# secretum-vault config
-[[rotation_policies]]
-path = "database/prod/password"
-schedule = "0 0 * * 0"  # Weekly on Sunday midnight
-max_age = "30d"
-
-[[rotation_policies]]
-path = "api/keys/stripe"
-schedule = "0 0 1 * *"  # Monthly on 1st
-max_age = "90d"
-```
-
-### Audit Log Format
-
-```json
-{
-  "timestamp": "2025-01-08T12:34:56Z",
-  "type": "request",
-  "auth": {
-    "client_token": "sha256:abc123...",

-# ADR-016: Schema-Driven Accessor Generation Pattern
-
-**Status**: Proposed
-**Date**: 2026-01-13
-**Author**: Architecture Team
-**Supersedes**: Manual accessor maintenance in `lib_provisioning/config/accessor.nu`
-
-## Context
-
-The `lib_provisioning/config/accessor.nu` file contains 1567 lines across 187 accessor functions. Analysis reveals that 95% of these functions follow
-an identical mechanical pattern:
-
-```javascript
-export def get-{field-name} [--config: record] {
-    config-get "{path.to.field}" {default_value} --config $config
-}
-```
-
-This represents significant technical debt:
-
-1. **Manual Maintenance Burden**: Adding a new config field requires manually writing a new accessor function
-2. **Schema Drift Risk**: No automated validation that accessor matches the actual Nickel schema
-3. **Code Duplication**: Nearly identical functions across 187 definitions
-4. **Testing Complexity**: Each accessor requires manual testing
-
-## Problem Statement
-
-**Current Architecture**:
-- Nickel schemas define configuration structure (source of truth)
-- Accessor functions manually mirror the schema structure
-- No automated synchronization between schema and accessors
-- High risk of accessor-schema mismatch
-
-**Key Metrics**:
-- 1567 lines of accessor code
-- 187 repetitive functions
-- ~95% code similarity
-
-## Decision
-
-Implement **Schema-Driven Accessor Generation**: automatically generate accessor functions from Nickel schema definitions.
-
-### Architecture
-
-```bash
-Nickel Schema (contracts.ncl)
-    ↓
-[Parse & Extract Schema Structure]
-    ↓
-[Generate Nushell Functions]
-    ↓
-accessor_generated.nu (800 lines)
-    ↓
-[Validation & Integration]
-    ↓
-CI/CD enforces: schema hash == generated code
-```
-
-### Generation Process
-
-1. **Schema Parsing**: Extract field paths, types, and defaults from Nickel contracts
-2. **Code Generation**: Create accessor functions with Nushell 0.109 compliance
-3. **Validation**: Verify generated code against schema
-4. **CI Integration**: Detect schema changes, validate generated code matches
-
-### Compliance Requirements
-
-**Nushell 0.109 Guidelines**:
-- No `try-catch` blocks (use `do-complete` pattern)
-- No `reduce --init` (use `reduce --fold`)
-- No mutable variables (use immutable bindings)
-- No type annotations on boolean flags
-- Use `each` not `map`, `is-not-empty` not `length`
-
-**Nickel Compliance**:
-- Schema-first design (schema is source of truth)
-- Type contracts enforce structure
-- `| doc` before `| default` ordering
-
-## Consequences
-
-### Positive
-
-- **Elimination of Manual Maintenance**: New config fields automatically get accessors
-- **Zero Schema Drift**: Automatic validation ensures accessors match schema
-- **Reduced Code Size**: 1567 lines → ~400 lines (manual core) + ~800 lines (generated)
-- **Type Safety**: Generated code guarantees type correctness
-- **Consistency**: All 187 functions use identical pattern
-
-### Negative
-
-- **Tool Complexity**: Generator must parse Nickel and emit valid Nushell
-- **CI/CD Changes**: Build must validate schema hash
-- **Initial Migration**: One-time effort to verify generated code matches manual versions
-
-## Implementation Strategy
-
-1. **Create Generator** (`tools/codegen/accessor_generator.nu`)
-   - Parse Nickel schema files
-   - Extract paths, types, defaults
-   - Generate valid Nushell code
-   - Emit with proper formatting
-
-2. **Generate Accessors** (`lib_provisioning/config/accessor_generated.nu`)
-   - Run generator on `provisioning/schemas/config/settings/contracts.ncl`
-   - Output 187 accessor functions
-   - Verify compatibility with existing code
-
-3. **Validation**
-   - Integration tests comparing manual vs generated output
-   - Signature validator ensuring generated functions match patterns
-   - CI check for schema hash validity
-
-4. **Gradual Adoption**
-   - Keep manual accessors temporarily
-   - Feature flag to switch between manual and generated
-   - Gradual migration of dependent code
-
-## Testing Strategy
-
-1. **Unit Tests**
-   - Each generated accessor returns correct type
-   - Default values applied correctly
-   - Path resolution handles nested fields
-
-2. **Integration Tests**
-   - Generated accessors produce identical output to manual versions
-   - Config loading pipeline works with generated accessors
-   - Fallback behavior preserved
-
-3. **Regression Tests**
-   - All existing config access patterns work
-   - Performance within 5% of manual version
-   - No breaking changes to public API

-- **ADR-011**: Nickel Migration (schema-first architecture)
-
-## Open Questions
-
-1. Should accessors be regenerated on every build or only on schema changes?
-2. How do we handle conditional fields (if X then Y)?
-3. What's the fallback strategy if generator fails?
-
-## Timeline
-
-- **Phase 1**: Generator implementation (foundation)
-- **Phase 2**: Generate and validate accessor functions
-- **Phase 3**: Integration tests and feature flags
-- **Phase 4**: Full migration and manual code removal
