-# Provisioning Core - Changes
+# Provisioning Core - Changelog
 
-**Date**: 2025-12-11
+**Date**: 2026-04-17
 **Repository**: provisioning/core
-**Changes**: CLI, libraries, plugins, and utilities updates
+**Status**: Nickel IaC (PRIMARY)
 
 ---
 
 ## 📋 Summary
 
-Updates to core CLI, Nushell libraries, plugins system, and utility scripts for the provisioning core system.
+Major refactor: three-layer DAG architecture with workspace composition, Unified
+Component Architecture (components + workflows + capabilities), Nickel-backed
+commands-registry with JSON cache for fast CLI startup, consolidated platform
+service manager, and completed Nushell 0.110/0.112 migration (no try/catch, no
+bash redirections). TTY stack moved from `shlib/` into `cli/tty-*`. Numerous new
+domain modules: `dag`, `components`, `workflow` engine, `images` lifecycle,
+workspace state/sync, ontoref queries, FIP handler.
+
+---
+
+## 🔄 Latest Release (2026-04-17)
+
+### Three-Layer DAG Architecture
+
+**Scope**: Workspace composition as a DAG with formula_id::task_name namespacing,
+health gates, conditions, and NATS subject emission.
+
+**New files**:
+- `nulib/main_provisioning/dag.nu` — `dag show/validate/export` (DOT/JSON/Mermaid)
+- `nulib/lib_provisioning/config/loader/dag.nu` — DAG config loader
+- `nulib/taskservs/dag-executor.nu` — taskserv-level DAG execution helper
+
+**Related**: ADR-020 (extension capability declarations), ADR-021 (workspace
+composition DAG). Orchestrator consumes composition via
+`WorkspaceComposition::into_workflow` and emits NATS events.
+
+### Unified Component Architecture
+
+**Scope**: Components + workflows + capabilities as first-class citizens
+(libre-daoshi plan, blocks A-H complete).
+
+**New files**:
+- `nulib/components/mod.nu` — component dispatch module
+- `nulib/main_provisioning/components.nu` — `validate capabilities/components`,
+  `component list/info`
+- `nulib/main_provisioning/workflow.nu` — full workflow engine: run/list/status/
+  validate, topological sort, NATS event emission (+605 lines)
+- `nulib/main_provisioning/extensions.nu` — `extensions capabilities/graph`
+- `nulib/main_provisioning/ontoref-queries.nu` — on+re-aware CLI queries
+  (describe component/databases/namespace/storage/workflow)
+
+### Commands-Registry & Fast-Path Dispatch
+
+**Scope**: Eliminate Nu startup cost on every `prvng` invocation.
+
+**New files**:
+- `nulib/commands-registry.ncl` — Nickel command catalog (314 lines)
+- `nulib/lib_provisioning/utils/command-registry.nu` — registry accessor
+- `nulib/scripts/validate-command.nu` — cache-aware command validator
+
+**Behavior**: `cli/provisioning` reads the JSON cache at
+`~/.cache/provisioning/commands-registry.json`, rebuilt automatically via
+`nickel export` when the `.ncl` source is newer. Single-char aliases
+(`s`, `t`, `c`, `e`, `w`, `j`, `b`, `o`, `a`) are expanded in bash before
+dispatch. `nulib/main_provisioning/ADDING_COMMANDS.md` documents the four-step
+procedure for new commands.
+
+### Platform Service Manager
+
+**New files**:
+- `nulib/lib_provisioning/platform/service-manager.nu` (+573 lines)
+- `nulib/lib_provisioning/platform/startup.nu` (+611 lines)
+- `nulib/lib_provisioning/utils/service-check.nu` (+255 lines)
+
+**Refactored**: `platform/autostart.nu`, `platform/bootstrap.nu`,
+`platform/health.nu`, `platform/target.nu` — unified lifecycle, health probes,
+and autostart logic.
+
+### Nushell 0.112.2 Migration
+
+**Scope**: Project-wide refactor driven by `scripts/refactor-try-catch.nu` and
+`scripts/refactor-try-catch-simplified.nu` to reach Nushell 0.112.2 compliance.
+
+**Enforced**:
+- No `try/catch` — all use `do { } | complete`
+- No bash redirections (`2>&1`, `2>/dev/null`)

 ## Installation
 
 ### Prerequisites
 
-- **Nushell 0.107.1+** - Primary shell and scripting environment
-- **KCL 0.11.2+** - Configuration language for infrastructure definitions
+- **Nushell 0.112.2** - Primary shell and scripting environment
+- **Nickel 1.15.1+** - Configuration language for infrastructure definitions
 - **SOPS 3.10.2+** - Secrets management (optional but recommended)
 - **Age 1.2.1+** - Encryption tool for secrets (optional)
 
 ### Adding to PATH
 
-To use the CLI globally, add it to your PATH:
+Recommended installation uses a symlink plus the `prvng` shell alias:
 
 ```bash
-# Create symbolic link
-ln -sf "$(pwd)/provisioning/core/cli/provisioning" /usr/local/bin/provisioning
+# Symlink the bash wrapper into ~/.local/bin

+# Provisioning CLI - Flow-Aware TTY Command Management
+
+## Architecture Overview
+
+The provisioning wrapper (`provisioning/core/cli/provisioning`) is a **flow controller** that manages three execution paths for command handling:
+
+1. **Standalone TTY** - Interactive commands that exit after execution
+2. **Pipeline TTY** - Interactive commands that output for piping to other commands
+3. **Regular** - Standard Nushell command processing
+
+This design enables:
+- Interactive commands (TTY input) without blocking Nushell
+- Inter-command piping of TTY output to subsequent commands
+- Same-command flow (TTY input → Nushell processing in one execution)
+- Daemon optimization for non-interactive commands
+
+## How Flow Management Works
+
+### Execution Flow
+
+```text
+User Command: provisioning <cmd> <args>
+       ↓
+Bash wrapper (provisioning)
+       ↓
+┌──────────────────────────────────────┐
+│ Phase 1: TTY Command Detection       │
+│ - Read tty-commands.conf registry    │
+│ - Match command pattern              │
+└──────────────────────────────────────┘
+       ↓
+       ├─→ Not a TTY command → Continue to Nushell (normal processing)
+       │
+       └─→ TTY command found → Check flow type
+              ↓
+              ├─→ flow=exit → Execute wrapper, exit immediately
+              ├─→ flow=pipe → Execute wrapper, output to stdout, exit (allows piping)
+              └─→ flow=continue → Execute wrapper, capture output, continue to Nushell
+                                   ($env.TTY_OUTPUT available in Nushell)
+```
+
+### Flow Types Explained
+
+#### 1. Standalone TTY Commands (flow=exit)
+
+**Use case**: Interactive forms, setup wizards, authentication dialogs
+
+**Example**: `provisioning setup wizard`
+
+**Flow**:
+
+```bash
+Bash wrapper → TTY filter detects "setup wizard" → flow=exit
+              ↓
+Execute wrapper: core/shlib/setup-wizard-tty.sh
+              ↓
+User interaction (TypeDialog form)
+              ↓
+Exit wrapper → Exit bash wrapper
+              ↓
+Never reaches Nushell
+```
+
+**Registry entry**:
+
+```bash
+"setup wizard" "core/shlib/setup-wizard-tty.sh" "exit"
+```
+
+#### 2. Pipeline TTY Commands (flow=pipe)
+
+**Use case**: Getting user input to pipe to another command
+
+**Example**: `provisioning auth get-key | provisioning deploy --api-key-stdin`
+
+**Flow**:
+
+```bash
+Bash wrapper → TTY filter detects "auth get-key" → flow=pipe
+              ↓
+Execute wrapper: core/shlib/auth-get-key-tty.sh
+              ↓
+User provides API key via TTY prompt
+              ↓
+Wrapper outputs API key to stdout
+              ↓
+Exit wrapper (process exits, pipe has captured output)
+              ↓
+Next command receives API key from stdin
+```
+
+**Registry entry**:
+
+```bash
+"auth get-key" "core/shlib/auth-get-key-tty.sh" "pipe"
+```
+
+**Wrapper requirements** (flow=pipe):
+- Must output result to stdout
+- Output must be newline-terminated
+- Exit with proper code (0=success, non-zero=error)
+
+#### 3. Continue-to-Nushell TTY Commands (flow=continue)
+
+**Use case**: TTY input that needs further processing in Nushell
+
+**Example**: `provisioning auth integrate --provider azure`
+
+**Flow**:
+
+```bash
+Bash wrapper → TTY filter detects "auth integrate" → flow=continue
+              ↓
+Execute wrapper: core/shlib/auth-integrate-tty.sh
+              ↓
+User provides credentials via TTY prompt
+              ↓
+Wrapper outputs credentials (usually JSON) to stdout
+              ↓
+Filter CAPTURES output to $TTY_OUTPUT environment variable
+              ↓
+Set $env.PROVISIONING_BYPASS_DAEMON=true (skip daemon)
+              ↓
+Return 0 WITHOUT EXITING (continue to Nushell)
+              ↓
+Nushell dispatcher receives both:
+  - CLI args: --provider azure
+  - TTY output: $env.TTY_OUTPUT (credentials JSON)
+              ↓
+Nushell script processes both, completes integration
+```
+
+**Registry entry**:
+
+```bash
+"auth integrate" "core/shlib/auth-integrate-tty.sh" "continue"
+```
+
+**Wrapper requirements** (flow=continue):
+- Must output result to stdout (usually JSON for structured data)
+- Exit with proper code (0=success, non-zero=error)
+
+**Nushell script requirements** (receives flow=continue output):
+
+```nushell
+export def "provisioning auth integrate" [--provider: string] {
+    # Check if TTY output exists (guard pattern)
+    let tty_output = ($env.TTY_OUTPUT? | default "")
+    if ($tty_output | is-empty) {
+        error make {msg: "No credentials provided via TTY"}
+    }
+
+    # Parse TTY output (credentials)
+    let credentials = ($tty_output | from json)
+
+    # Use both TTY input ($credentials) and CLI args ($provider)
+    # Complete integration logic...
+
+    # Clear sensitive data after use
+    hide-env TTY_OUTPUT
+}
+```
+
+#### 4. Regular Commands
+
+**Use case**: Standard provisioning operations
+
+**Example**: `provisioning server list`
+
+**Flow**:
+
+```bash
+Bash wrapper → TTY filter checks registry → Not found → Return 1
+              ↓
+Continue to normal processing:
+  - Fast-path checks (help, workspace, env, etc.)
+  - Daemon check (if applicable)
+  - Nushell dispatcher
+```
+
+## Registry Format
+
+**File**: `provisioning/core/cli/tty-commands.conf`
+
+**Three-field format**: `"PATTERN" "WRAPPER_PATH" "FLOW_TYPE"`
+
+```bash
+# Exact command match (e.g., "setup wizard" matches "provisioning setup wizard")
+"setup wizard" "core/shlib/setup-wizard-tty.sh" "exit"
+
+# Paths are relative to $PROVISIONING
+"auth get-key" "core/shlib/auth-get-key-tty.sh" "pipe"
+
+# Flow types: exit | pipe | continue
+"auth integrate" "core/shlib/auth-integrate-tty.sh" "continue"
+```
+
+### Flow Type Decision Matrix
+
+| Interaction | Flow Type | Example |
+| ----------- | --------- | ------- |
+| Interactive form, no output needed | `exit` | Setup wizard, auth login |
+| User input → pipe to next command | `pipe` | API key for piping to deploy |
+| User input → same-command Nushell processing | `continue` | Credentials for integration |
+
+## Adding New TTY Commands
+
+### Step 1: Create Wrapper Script
+
+Create wrapper in `provisioning/core/shlib/`:
+
+```bash
+#!/bin/bash
+set -euo pipefail
+
+main() {
+    local input
+
+    # Get input from user
+    read -rsp "Prompt: " input
+    echo  # Newline
+
+    # For flow=pipe: output to stdout
+    # For flow=continue: output to stdout (will be captured by filter)
+    echo "$input"
+
+    return 0
+}
+
+main "$@"
+```
+
+Make it executable:
+
+```bash
+chmod +x provisioning/core/shlib/your-wrapper-tty.sh
+```
+
+### Step 2: Add Registry Entry
+
+Edit `provisioning/core/cli/tty-commands.conf`:
+
+```bash
+# Standalone TTY
+"your command" "core/shlib/your-wrapper-tty.sh" "exit"
+
+# Pipeline TTY
+"get something" "core/shlib/get-something-tty.sh" "pipe"
+
+# Continue-to-Nushell TTY
+"setup something" "core/shlib/setup-something-tty.sh" "continue"
+```
+
+### Step 3: No Wrapper Modifications Required
+
+The provisioning wrapper automatically:
+- Reads registry
+- Matches command pattern
+- Routes based on flow type
+- Handles all three flows
+
+**No need to modify provisioning wrapper for new commands!**
+
+## Wrapper Script Requirements
+
+### For All Wrappers
+
+- **Shebang**: `#!/bin/bash`
+- **Safety**: `set -euo pipefail`
+- **Arguments**: Accept `"${@}"` from wrapper
+- **Exit codes**: 0=success, non-zero=error
+- **Validation**: `shellcheck` passes without warnings
+
+### For flow=exit Wrappers
+
+- Complete all interaction in wrapper
+- Exit with proper code (0=success, non-zero=error)
+- Output shown directly to user (from wrapper)
+
+### For flow=pipe Wrappers
+
+- Get input from user (TTY)
+- Output result to stdout
+- Output must be newline-terminated
+- Exit with proper code (0=success, non-zero=error)
+
+### For flow=continue Wrappers
+
+- Get input from user (TTY)
+- Output result to stdout (usually JSON)
+- Exit with proper code (0=success, non-zero=error)
+- Filter captures output → $TTY_OUTPUT
+- Nushell script reads $env.TTY_OUTPUT
+
+## Environment Variables
+
+### Exported by Filter (flow=continue only)
+
+- **`$TTY_OUTPUT`**: Captured output from wrapper (available in Nushell as `$env.TTY_OUTPUT`)
+- **`$PROVISIONING_BYPASS_DAEMON`**: Set to "true" to skip daemon (flow=continue automatically sets this)
+- **`$TTY_WRAPPER_EXECUTED`**: Set to "true" when TTY wrapper was executed
+
+### Usage in Nushell
+
+```nushell
+# Access TTY output in Nushell script
+export def "provisioning auth integrate" [--provider: string] {
+    let tty_output = ($env.TTY_OUTPUT? | default "")
+
+    # Parse if JSON
+    let creds = ($tty_output | from json)
+
+    # Use both TTY output and CLI args
+    integration-logic $provider $creds
+
+    # Clear after use (security)
+    hide-env TTY_OUTPUT
+}
+```
+
+## Daemon Interaction
+
+The flow filter intelligently manages daemon usage:
+
+### For flow=exit and flow=pipe
+- ✅ **Daemon can be used** - No stdin required
+- No output needs to be captured and passed to Nushell
+- Daemon optimization available (~100ms startup improvement)
+
+### For flow=continue
+- ❌ **Daemon MUST be bypassed** - stdin required for TTY interaction
+- `PROVISIONING_BYPASS_DAEMON=true` automatically set by filter
+- Direct Nushell execution (preserves stdin for TTY)
+- Zero overhead (same as non-daemon path)
+
+## Testing TTY Commands
+
+### Test Standalone (flow=exit)
+
+```bash
+provisioning setup wizard
+# Expected: TypeDialog form, user interaction, exits
+```
+
+### Test Pipeline (flow=pipe)
+
+```bash
+provisioning auth get-key | wc -c
+# Expected: Prompts for API key, outputs to pipe
+```
+
+### Test Continue (flow=continue)
+
+```bash
+provisioning auth integrate --provider azure
+# Expected: Prompts for credentials, passes to Nushell with $env.TTY_OUTPUT
+```
+
+### Test Regular Command
+
+```bash
+provisioning server list
+# Expected: Normal Nushell processing
+```
+
+## Troubleshooting
+
+### Command Not Executed
+- **Check**: Is command in tty-commands.conf?
+- **Check**: Does pattern exactly match command?
+- **Check**: Is wrapper path correct and executable?
+
+### Wrapper Not Found
+- **Error message**: `Warning: TTY wrapper not found or not executable: /path/to/wrapper`
+- **Check**: File exists at `$PROVISIONING/wrapper-path`
+- **Check**: File is executable: `chmod +x wrapper-path`
+
+### Output Not Piping (flow=pipe)
+- **Check**: Wrapper outputs to stdout (not stderr)
+- **Check**: Output is newline-terminated: `echo "output"`
+- **Check**: No daemon interference (PROVISIONING_BYPASS_DAEMON not set)
+
+### Nushell Not Receiving Output (flow=continue)
+- **Check**: `$env.TTY_OUTPUT` accessible in Nushell: `echo $env.TTY_OUTPUT`
+- **Check**: Output format (usually JSON): `echo $env.TTY_OUTPUT | from json`
+- **Check**: Wrapper exits with 0: `echo $?`
+
+## Implementation Details
+
+### Filter Location and Function
+
+**File**: `provisioning/core/cli/tty-filter.sh`
+**Function**: `filter_tty_command()`
+**Lines**: ~104 (includes documentation and three flow paths)
+
+### Integration in Wrapper
+
+**File**: `provisioning/core/cli/provisioning`
+**Lines**: ~20 (sources filter, calls function, continues to Nushell)
+
+### Registry Parsing
+
+- **File**: `provisioning/core/cli/tty-commands.conf`
+- **Method**: Line-by-line bash read (no jq dependency)
+- **Format**: Three-field bash array (bash-compatible)
+- **Sections**: Organized by flow type for clarity
+
+## Performance Implications
+
+### startup time
+- **flow=exit/pipe**: Daemon available for startup optimization (~100ms improvement)
+- **flow=continue**: Daemon bypassed (stdin needed), ~500ms traditional path
+- **Regular commands**: Normal daemon/non-daemon path selection
+
+### Memory
+- **flow=continue**: Wrapper output stored in `$TTY_OUTPUT` environment variable
+- Typical size: < 1KB (credentials, keys, etc.)
+- Cleared after Nushell processing (or via `hide-env`)
+
+## Security Considerations
+
+### Sensitive Data in $TTY_OUTPUT
+
+- **Credentials** captured in `$TTY_OUTPUT`
+- **Nushell scripts should clear after use**: `hide-env TTY_OUTPUT`
+- **Wrapper output may be logged**: Use standard Unix conventions (hide passwords from output)
+
+### Wrapper Location Restriction
+
+- Wrappers should be in `provisioning/core/shlib/` or `provisioning/scripts/`
+- Registry reads only wrappers from these trusted locations
+- Pattern validation prevents arbitrary script execution
+
+### No Shell Injection
+
+- All variables quoted: `"$variable"`
+- No eval or command substitution with user input
+- Pattern matching uses exact string match (no regex)
+
+## Related Files
+
+- **Filter**: `provisioning/core/cli/tty-filter.sh`
+- **Registry**: `provisioning/core/cli/tty-commands.conf`
+- **Wrapper**: `provisioning/core/cli/provisioning`
+- **Example wrappers**: `provisioning/core/shlib/auth-get-key-tty.sh`, `provisioning/core/shlib/auth-integrate-tty.sh`
+
+## Key Insights
+
+The provisioning wrapper is not just a pass-through - it's a **flow controller** that:
+
+1. **Detects TTY requirements** (registry matching)
+2. **Manages execution paths** (three flows: exit, pipe, continue)
+3. **Controls exit behavior** (standalone vs pipeline vs same-command)
+4. **Enables inter-command piping** (TTY output to pipes)
+5. **Supports Nushell integration** (TTY→Nushell continuation)
+6. **Optimizes with daemon** (skip when stdin needed)
+
+This solves:
+- "el tema no es sólo un filter" → ✅ Flow controller with three execution paths
+- "cómo gestionar el flow por medio del provisioning command" → ✅ Registry + flow types
+- "usamos tty para input de una API key, se lo pasamos a un script de nushell" → ✅ Pipeline + continue flows

+# DAEMON ROUTING - ENABLED (Phase 3.7: CLI Daemon Integration)
+# ============================================================================
+# Redesigned daemon with pre-loaded Nushell environment (no CLI callback).
+# Routes eligible commands to HTTP daemon for <100ms execution.
+# Gracefully falls back to full load if daemon unavailable.
+#
+# ARCHITECTURE:
+#   1. Check daemon health (curl with 5ms timeout)
+#   2. Route eligible commands to daemon via HTTP POST
+#   3. Fall back to full load if daemon unavailable
+#   4. Zero breaking changes (graceful degradation)
+#
+# PERFORMANCE:
+#   - With daemon: <100ms for ALL commands
+#   - Without daemon: ~430ms (normal behavior)
+#   - Daemon fallback: Automatic, user sees no difference

+# DAEMON ROUTING - ENABLED (Phase 3.7: CLI Daemon Integration)
+# ============================================================================
+# Redesigned daemon with pre-loaded Nushell environment (no CLI callback).
+# Routes eligible commands to HTTP daemon for <100ms execution.
+# Gracefully falls back to full load if daemon unavailable.
+#
+# ARCHITECTURE:
+#   1. Check daemon health (curl with 5ms timeout)
+#   2. Route eligible commands to daemon via HTTP POST
+#   3. Fall back to full load if daemon unavailable
+#   4. Zero breaking changes (graceful degradation)
+#
+# PERFORMANCE:
+#   - With daemon: <100ms for ALL commands
+#   - Without daemon: ~430ms (normal behavior)
+#   - Daemon fallback: Automatic, user sees no difference

-# FormInquire Integration System
-
-Dynamic form generation using Jinja2 templates rendered with `nu_plugin_tera`.
-
-## Architecture
-
-```
-provisioning/core/forminquire/
-├── templates/                      # Jinja2 form templates (.j2)
-│   ├── setup-wizard.form.j2
-│   ├── workspace-init.form.j2
-│   ├── settings-update.form.j2
-│   ├── server-delete-confirm.form.j2
-│   └── ...more templates
-├── nulib/
-│   └── forminquire.nu             # Nushell integration functions
-└── wrappers/
-    └── form.sh                    # Bash wrapper for FormInquire
-```
-
-## How It Works
-
-1. **Template Rendering**: Jinja2 templates are rendered with data from config files
-2. **Form Generation**: Rendered templates are saved as TOML forms in cache
-3. **User Interaction**: FormInquire binary presents the form to user
-4. **Result Processing**: JSON output from FormInquire is returned to calling code
-
-```
-Config Data → Template Rendering → Form Generation → FormInquire → JSON Output
-             (nu_plugin_tera)      (cache: ~/.cache/)  (interactive)
-```
-
-## Quick Examples
-
-### Settings Update with Current Values as Defaults
-
-```nushell
-use provisioning/core/forminquire/nulib/forminquire.nu *
-
-# Load current settings and show form with them as defaults
-let result = (settings-update-form)
-
-if $result.success {
-    # Process updated settings
-    print $"Updated: ($result.values | to json)"
-}
-```
-
-### Setup Wizard
-
-```nushell
-let result = (setup-wizard-form)
-
-if $result.success {
-    print "Setup configuration:"
-    print ($result.values | to json)
-}
-```
-
-### Workspace Initialization
-
-```nushell
-let result = (workspace-init-form "my-workspace")
-
-if $result.success {
-    print "Workspace created with settings:"
-    print ($result.values | to json)
-}
-```
-
-### Server Delete Confirmation
-
-```nushell
-let confirm = (server-delete-confirm-form "web-01" "192.168.1.10" "running")
-
-if $confirm.success {
-    let confirmation_text = $confirm.values.confirmation_text
-    let final_confirm = $confirm.values.final_confirm
-
-    if ($confirmation_text == "web-01" and $final_confirm) {
-        print "Deleting server..."
-    }
-}
-```
-
-## Template Variables
-
-All templates have access to:
-
-### Automatic Variables (always available)
-- `now_iso`: Current timestamp in ISO 8601 format
-- `home_dir`: User's home directory
-- `username`: Current username
-- `provisioning_root`: Provisioning root directory
-
-### Custom Variables (passed per form)
-- Settings from `config.defaults.toml`
-- User preferences from `~/.config/provisioning/user_config.yaml`
-- Workspace configuration from workspace `config.toml`
-- Any custom data passed to the form function
-
-## Cache Management
-
-Forms are cached at: `~/.cache/provisioning/forms/`
-
-### Cleanup Old Forms
-
-```nushell
-let cleanup_result = (cleanup-form-cache)
-print $"Cleaned up ($cleanup_result.cleaned) old form files"
-```
-
-### List Generated Forms
-
-```nushell
-list-cached-forms
-```
-
-## Template Syntax
-
-Templates use Jinja2 syntax with macros for common form elements:
-
-```jinja2
-[items.my_field]
-type = "text"
-prompt = "Enter value"
-default = "{{ my_variable }}"
-help = "Help text here"
-required = true
-```
-
-### Available Form Types
-
-- `text`: Text input
-- `select`: Dropdown selection
-- `confirm`: Yes/No confirmation
-- `password`: Masked password input
-- `multiselect`: Multiple selection
-
-## Available Functions
-
-### Form Execution
-
-- `interactive-form [name] [template] [data]` - Complete form flow
-- `render-template [template_name] [data]` - Render template only
-- `generate-form [form_name] [template_name] [data]` - Generate TOML form
-- `run-form [form_path]` - Execute FormInquire with form
-
-### Config Loading
-
-- `load-user-preferences` - Load user preferences from config
-- `load-workspace-config [workspace_name]` - Load workspace settings
-- `load-system-defaults` - Load system defaults
-- `get-form-context [workspace_name] [custom_data]` - Merged config context
-
-### Convenience Functions
-
-- `settings-update-form` - Update system settings
-- `setup-wizard-form` - Run setup wizard
-- `workspace-init-form [name]` - Initialize workspace
-- `server-delete-confirm-form [name] [ip] [status]` - Delete confirmation
-
-### Utilities
-
-- `list-templates` - List available templates
-- `list-cached-forms` - List generated forms in cache
-- `cleanup-form-cache` - Remove old cached forms
-
-## Shell Integration
-
-Use the bash wrapper for shell scripts:
-
-```bash
-#!/bin/bash
-
-# Generate form with Nushell
-nu -c "use forminquire *; interactive-form 'my-form' 'my-template' {foo: 'bar'}" > /tmp/form.toml
-
-# Or use form.sh wrapper directly
-./provisioning/core/forminquire/wrappers/form.sh /path/to/form.toml json
-```
-
-## Performance Notes
-
-- **First form**: ~200ms (template rendering + form generation)
-- **Subsequent forms**: ~50ms (cached config loading)
-- **User interaction**: Depends on FormInquire response time
-- **Form cache**: Automatically cleaned after 1+ days
-
-## Dependencies
-
-- `forminquire` - FormInquire binary (in PATH)
-- `nu_plugin_tera` - Nushell Jinja2 template plugin
-- `Nushell 0.109.0+` - Core scripting language
-
-## Error Handling
-
-All functions return structured results:
-
-```nushell
-{
-    success: bool          # Operation succeeded
-    error: string          # Error message (empty if success)
-    form_path: string      # Generated form path (if applicable)
-    values: record         # FormInquire output values
-}
-```
-
-## Adding New Forms
-
-1. Create template in `templates/` with `.form.j2` extension
-2. Create convenience function in `forminquire.nu` like `my-form-function`
-3. Use in scripts: `my-form-function [args...]`
-
-Example:
-
-```jinja2
-# templates/my-form.form.j2
-[meta]
-title = "My Custom Form"
-[items.field1]
-type = "text"
-prompt = "Enter value"
-default = "{{ default_value }}"
-```
-
-```nushell
-# In forminquire.nu
-export def my-form-function [default_value: string = ""] {
-    interactive-form "my-form" "my-form" {default_value: $default_value}
-}
-```
-
-## Limitations
-
-- Template rendering uses Jinja2 syntax only
-- FormInquire must be in PATH
-- `nu_plugin_tera` must be installed for template rendering
-- Form output limited to FormInquire-supported types

-provisioning platform start
-
-# Start specific services with dependencies
-provisioning platform start control-center
-
-# Check platform status
-provisioning platform status
-
-# Check platform health
-provisioning platform health
-```
-
-### Manage Individual Services
-
-```bash
-# List all services
-provisioning services list
-
-# Start service (with pre-flight checks)
-provisioning services start orchestrator
-
-# Check service health
-provisioning services health orchestrator
-
-# View service logs
-provisioning services logs orchestrator --follow
-
-# Stop service (with dependent check)
-provisioning services stop orchestrator
-```
-
-### Dependency Management
-
-```bash
-# View dependency graph
-provisioning services dependencies
-
-# View specific service dependencies
-provisioning services dependencies control-center
-
-# Check if service can be stopped safely
-nu -c "use lib_provisioning/services/mod.nu *; can-stop-service orchestrator"
-```
-
-### Health Monitoring
-
-```bash
-# Continuous health monitoring
-provisioning services monitor orchestrator --interval 30
-
-# One-time health check
-provisioning services health orchestrator
-```
-
-### Validation
-
-```bash
-# Validate all services
-provisioning services validate
-
-# Check readiness
-provisioning services readiness
-
-# Check required services for operation
-provisioning services check server
-```
-
----
-
-## Integration Points
-
-### 1. Command Dispatcher
-
-Pre-flight checks integrated into dispatcher:
-
-```nushell
-# Before executing operation, check required services
-let preflight = (check-required-services $task)
-
-if not $preflight.all_running {
-    if $preflight.can_auto_start {
-        auto-start-required-services $task
-    } else {
-        error "Required services not running"
-    }
-}
-```
-
-### 2. Workflow System
-
-Orchestrator automatically starts when workflows are submitted:
-
-```bash
-provisioning workflow submit my-workflow
-# Orchestrator auto-starts if not running
-```
-
-### 3. Test Environments
-
-Orchestrator required for test environment operations:
-
-```bash
-provisioning test quick kubernetes
-# Orchestrator auto-starts if needed
-```

-    - Interactive mode with follow-up questions
-    - Automatic validation and improvement
-
-  🛠 Files Created/Enhanced:
-
-  Core AI Library
-
-  - core/nulib/lib_provisioning/ai/lib.nu - Core AI functionality and API integration
-  - core/nulib/lib_provisioning/ai/templates.nu - KCL template generation
-  - core/nulib/lib_provisioning/ai/webhook.nu - Chat/webhook processing
-  - core/nulib/lib_provisioning/ai/mod.nu - Module exports
-
-  Command Interface
-
-  - core/nulib/main_provisioning/ai.nu - AI command interface (already existed, enhanced)
-  - core/nulib/main_provisioning/generate_ai.nu - Enhanced generation commands
-
-  Configuration Files
-
-  - kcl/settings.k - Added AIProvider schema (already existed)
-  - templates/ai.yaml - AI configuration template
-  - templates/default_context.yaml - Enhanced with AI settings
-
-  Documentation
-
-  - core/nulib/lib_provisioning/ai/README.md - Comprehensive documentation
-
-  🚀 Usage Examples:
-
-  Generate Infrastructure with Natural Language
-
-  # Interactive generation
-  ./provisioning ai generate --interactive
-
-  # Generate Kubernetes servers
-  ./provisioning generate-ai servers "3-node Kubernetes cluster with Ceph storage and monitoring" --provider
-   upcloud --validate
-
-  # Generate AWS production defaults
-  ./provisioning ai gen -t defaults -p aws -i "High-availability production environment in us-west-2"
-
-  # Improve existing configurations
-  ./provisioning ai improve -i servers.k -o optimized_servers.k
-
-  AI Chat Interface
-
-  # Start interactive chat
-  ./provisioning ai chat
-
-  # Single query
-  ./provisioning ai chat -i "How do I set up persistent storage for Kubernetes?"
-
-  # Test AI functionality
-  ./provisioning ai test
-
-  Webhook Integration
-
-  # Process webhook messages
-  curl -X POST http://your-server/webhook \
-    -H "Content-Type: application/json" \
-    -d '{"message": "generate 3 kubernetes servers", "user_id": "user123"}'
-
-  ⚙️ Configuration:
-
-  Environment Variables
-
-  export PROVISIONING_AI_ENABLED=true
-  export PROVISIONING_AI_PROVIDER="openai"
-  export OPENAI_API_KEY="your-api-key"
-
-  KCL Configuration
-
-  ai = AIProvider {
-      enabled = True
-      provider = "openai"
-      model = "gpt-4"
-      max_tokens = 2048
-      temperature = 0.3
-      enable_template_ai = True
-      enable_query_ai = True
-      enable_webhook_ai = False
-  }
-
-  🎯 Capabilities:
-
-  1. Smart KCL Generation - Understands infrastructure requirements and generates proper KCL configurations
-  2. Provider Intelligence - Optimizes configurations for specific cloud providers
-  3. Interactive Enhancement - Asks clarifying questions to improve generation quality
-  4. Validation & Fixing - Automatically validates and fixes KCL syntax issues
-  5. Natural Language Queries - Process questions about infrastructure in plain English
-  6. Chat Integration - Slack/Discord bot capabilities for team collaboration
-  7. Template Improvement - AI-powered optimization of existing configurations
-
-  🔄 Integration with Existing System:
-
-  The AI system seamlessly integrates with your existing provisioning workflow:
-  1. Generate configurations with AI
-  2. Validate using existing KCL tools
-  3. Apply using standard provisioning commands
-  4. Monitor and iterate with AI assistance
-
-  This creates a powerful natural language interface for your infrastructure automation system, making it
-  accessible to team members who may not be familiar with KCL syntax while maintaining all the precision and
-   power of your existing tooling.
-
-  The AI implementation follows the same patterns as your SOPS/KMS integration - it's modular, configurable,
-   and maintains backward compatibility while adding powerful new capabilities! 🚀

-# Modular Configuration Loading Architecture
-
-## Overview
-
-The configuration system has been refactored into modular components to achieve 2-3x performance improvements for regular commands while maintaining full functionality for complex operations.
-
-## Architecture Layers
-
-### Layer 1: Minimal Loader (0.023s)
-**File**: `loader-minimal.nu` (~150 lines)
-
-Contains only essential functions needed for:
-- Workspace detection
-- Environment determination
-- Project root discovery
-- Fast path detection
-
-**Exported Functions**:
-- `get-active-workspace` - Get current workspace
-- `detect-current-environment` - Determine dev/test/prod
-- `get-project-root` - Find project directory
-- `get-defaults-config-path` - Path to default config
-- `check-if-sops-encrypted` - SOPS file detection
-- `find-sops-config-path` - Locate SOPS config
-
-**Used by**:
-- Help commands (help infrastructure, help workspace, etc.)
-- Status commands
-- Workspace listing
-- Quick reference operations
-
-### Layer 2: Lazy Loader (decision layer)
-**File**: `loader-lazy.nu` (~80 lines)
-
-Smart loader that decides which configuration to load:
-- Fast path for help/status commands
-- Full path for operations that need config
-
-**Key Function**:
-- `command-needs-full-config` - Determines if full config required
-
-### Layer 3: Full Loader (0.091s)
-**File**: `loader.nu` (1990 lines)
-
-Original comprehensive loader that handles:
-- Hierarchical config loading
-- Variable interpolation
-- Config validation
-- Provider configuration
-- Platform configuration
-
-**Used by**:
-- Server creation
-- Infrastructure operations
-- Deployment commands
-- Anything needing full config
-
-## Performance Characteristics
-
-### Benchmarks
-
-| Operation | Time | Notes |
-|-----------|------|-------|
-| Workspace detection | 0.023s | 23ms for minimal load |
-| Full config load | 0.091s | ~4x slower than minimal |
-| Help command | 0.040s | Uses minimal loader only |
-| Status command | 0.030s | Fast path, no full config |
-| Server operations | 0.150s+ | Requires full config load |
-
-### Performance Gains
-
-- **Help commands**: 30-40% faster (40ms vs 60ms with full config)
-- **Workspace operations**: 50% faster (uses minimal loader)
-- **Status checks**: Nearly instant (23ms)
-
-## Module Dependency Graph
-
-```
-Help/Status Commands
-    ↓
-loader-lazy.nu
-    ↓
-loader-minimal.nu (workspace, environment detection)
-    ↓
-     (no further deps)
-
-Infrastructure/Server Commands
-    ↓
-loader-lazy.nu
-    ↓
-loader.nu (full configuration)
-    ├── loader-minimal.nu (for workspace detection)
-    ├── Interpolation functions
-    ├── Validation functions
-    └── Config merging logic
-```
-
-## Usage Examples
-
-### Fast Path (Help Commands)
-```nushell
-# Uses minimal loader - 23ms
-./provisioning help infrastructure
-./provisioning workspace list
-./provisioning version
-```
-
-### Medium Path (Status Operations)
-```nushell
-# Uses minimal loader with some full config - ~50ms
-./provisioning status
-./provisioning workspace active
-./provisioning config validate
-```
-
-### Full Path (Infrastructure Operations)
-```nushell
-# Uses full loader - ~150ms
-./provisioning server create --infra myinfra
-./provisioning taskserv create kubernetes
-./provisioning workflow submit batch.yaml
-```
-
-## Implementation Details
-
-### Lazy Loading Decision Logic
-
-```nushell
-# In loader-lazy.nu
-let is_fast_command = (
-    $command == "help" or
-    $command == "status" or
-    $command == "version"
-)
-
-if $is_fast_command {
-    # Use minimal loader only (0.023s)
-    get-minimal-config
-} else {
-    # Load full configuration (0.091s)
-    load-provisioning-config
-}
-```
-
-### Minimal Config Structure
-
-The minimal loader returns a lightweight config record:
-
-```nushell
-{
-    workspace: {
-        name: "librecloud"
-        path: "/path/to/workspace_librecloud"
-    }
-    environment: "dev"
-    debug: false
-    paths: {
-        base: "/path/to/workspace_librecloud"
-    }
-}
-```
-
-This is sufficient for:
-- Workspace identification
-- Environment determination
-- Path resolution
-- Help text generation
-
-### Full Config Structure
-
-The full loader returns comprehensive configuration with:
-- Workspace settings
-- Provider configurations
-- Platform settings
-- Interpolated variables
-- Validation results
-- Environment-specific overrides
-
-## Migration Path
-
-### For CLI Commands
-
-1. Commands are already categorized (help, workspace, server, etc.)
-2. Help system uses fast path (minimal loader)
-3. Infrastructure commands use full path (full loader)
-4. No changes needed to command implementations
-
-### For New Modules
-
-When creating new modules:
-1. Check if full config is needed
-2. If not, use `loader-minimal.nu` functions only
-3. If yes, use `get-config` from main config accessor
-
-## Future Optimizations
-
-### Phase 2: Per-Command Config Caching
-- Cache full config for 60 seconds
-- Reuse config across related commands
-- Potential: Additional 50% improvement
-
-### Phase 3: Configuration Profiles
-- Create thin config profiles for common scenarios
-- Pre-loaded templates for workspace/infra combinations
-- Fast switching between profiles
-
-### Phase 4: Parallel Config Loading
-- Load workspace and provider configs in parallel
-- Async validation and interpolation
-- Potential: 30% improvement for full config load
-
-## Maintenance Notes
-
-### Adding New Functions to Minimal Loader
-Only add if:
-1. Used by help/status commands
-2. Doesn't require full config
-3. Performance-critical path
-
-### Modifying Full Loader
-- Changes are backward compatible
-- Validate against existing config files
-- Update tests in test suite
-
-### Performance Testing
-```bash
-# Benchmark minimal loader
-time nu -n -c "use loader-minimal.nu *; get-active-workspace"
-
-# Benchmark full loader
-time nu -c "use config/accessor.nu *; get-config"
-
-# Benchmark help command
-time ./provisioning help infrastructure
-```

-# Extension System Quick Start Guide
-
-Get started with the Extension Loading System in 5 minutes.
-
-## Prerequisites
-
-1. **OCI Registry** (optional, for OCI features):
-   ```bash
-   # Start local registry
-   docker run -d -p 5000:5000 --name registry registry:2
-   ```
-
-2. **Nushell 0.107+**:
-   ```bash
-   nu --version
-   ```
-
-## Quick Start
-
-### 1. Load an Extension
-
-```bash
-# Load latest from auto-detected source
-provisioning ext load kubernetes
-
-# Load specific version
-provisioning ext load kubernetes --version 1.28.0
-
-# Load from specific source
-provisioning ext load redis --source oci
-```
-
-### 2. Search for Extensions
-
-```bash
-# Search all sources
-provisioning ext search kube
-
-# Search OCI registry
-provisioning ext search postgres --source oci
-```
-
-### 3. List Available Extensions
-
-```bash
-# List all
-provisioning ext list
-
-# Filter by type
-provisioning ext list --type taskserv
-
-# JSON format
-provisioning ext list --format json
-```
-
-### 4. Manage Cache
-
-```bash
-# Show cache stats
-provisioning ext cache stats
-
-# List cached
-provisioning ext cache list
-
-# Clear cache
-provisioning ext cache clear --all
-```
-
-### 5. Publish an Extension
-
-```bash
-# Create extension
-mkdir -p my-extension/{kcl,scripts}
-
-# Create manifest
-cat > my-extension/extension.yaml <<EOF
-extension:
-  name: my-extension
-  version: 1.0.0
-  type: taskserv
-  description: My awesome extension
-EOF
-
-# Publish to OCI
-provisioning ext publish ./my-extension --version 1.0.0
-```
-
-## Configuration
-
-### Enable OCI Registry
-
-Edit `workspace/config/local-overrides.toml`:
-
-```toml
-[oci]
-registry = "localhost:5000"
-namespace = "provisioning-extensions"
-auth_token_path = "~/.provisioning/oci-token"
-
-[extensions]
-source_type = "auto"  # auto, oci, gitea, local
-```
-
-### Test OCI Connection
-
-```bash
-provisioning ext test-oci
-```
-
-## Common Workflows
-
-### Workflow 1: Install Taskserv from OCI
-
-```bash
-# Search for taskserv
-provisioning ext search kubernetes --source oci
-
-# Load it
-provisioning ext load kubernetes --version ^1.28.0
-
-# Use in provisioning
-provisioning taskserv create kubernetes
-```
-
-### Workflow 2: Develop and Test Locally
-
-```bash
-# Copy to local path
-cp -r my-extension ~/.provisioning-extensions/taskservs/
-
-# Load locally
-provisioning ext load my-extension --source local
-
-# Test
-provisioning taskserv create my-extension --check
-
-# Publish when ready
-provisioning ext publish ./my-extension --version 1.0.0
-```
-
-### Workflow 3: Offline Usage
-
-```bash
-# Pull extensions to cache while online
-provisioning ext pull kubernetes --version 1.28.0
-provisioning ext pull redis --version 7.0.0
-provisioning ext pull postgres --version 15.0.0
-
-# Work offline - uses cache
-provisioning ext load kubernetes
-provisioning ext load redis
-```
-
-## Extension Structure

-## Troubleshooting
-
-### Extension Not Found
-
-```bash
-# Discover available extensions
-provisioning ext discover
-
-# Search by name
-provisioning ext search <name>
-
-# Check specific source
-provisioning ext list --source oci
-```
-
-### OCI Registry Issues
-
-```bash
-# Test connection
-provisioning ext test-oci
-
-# Check registry is running
-curl http://localhost:5000/v2/
-
-# View OCI config
-provisioning env | grep OCI
-```
-
-### Cache Problems
-
-```bash
-# Clear and rebuild
-provisioning ext cache clear --all
-
-# Pull fresh copy
-provisioning ext pull <name> --force
-```

+#! Fluent i18n translation daemon functions

+#! Provides high-performance message translation via HTTP API using Mozilla's Fluent.
+#! The CLI daemon's Fluent engine offers 50-100x better performance than using
+#! the nu_plugin_fluent plugin due to aggressive caching and no process spawning.
+#!
+#! Performance:
+#! - Single translation: ~1-5ms uncached, ~0.1-0.5ms cached (vs ~50ms with plugin)
+#! - Batch 10 translations: ~10-20ms with cache
+#! - Cache hit ratio: 75-80% on typical workloads

-5. **Collaboration Features**
-   - Pull request workflows
-   - Code review integration
-   - Team management
-
----
-
-## Known Limitations
-
-1. **Comment API**: Gitea basic API doesn't support adding comments to issues directly
-2. **SSH Keys**: SSH key management not yet implemented
-3. **Webhooks**: Webhook creation supported in schema but not automated
-4. **Binary Deployment**: Process management for binary mode is basic
-
----
-
-## Security Considerations
-
-1. **Token Storage**: Always use SOPS encryption for tokens
-2. **Repository Privacy**: Default to private repositories
-3. **Lock Validation**: Validate lock ownership before release
-4. **Token Rotation**: Implement regular token rotation
-5. **Audit Logging**: All lock operations are tracked via issues
-
----
-
-## Performance Notes
-
-1. **API Rate Limiting**: Gitea has rate limits, batch operations may need throttling
-2. **Large Files**: Git LFS not yet integrated for large workspace files
-3. **Lock Cleanup**: Run cleanup periodically to prevent issue buildup
-4. **Docker Resources**: Monitor container resources for local deployments
-
----
-
-## Conclusion
-
-The Gitea integration is **complete and production-ready** with:
-
-- ✅ 95+ functions across 6 modules
-- ✅ 13 KCL schemas for configuration
-- ✅ 30+ CLI commands
-- ✅ Comprehensive testing suite
-- ✅ Complete documentation (650+ lines)
-- ✅ Docker and binary deployment support
-- ✅ Workspace git integration
-- ✅ Distributed locking mechanism
-- ✅ Extension publishing workflow
-
-The implementation follows all PAP principles:
-- Configuration-driven (KCL schemas)
-- Modular architecture (6 focused modules)
-- Idiomatic Nushell (explicit types, pure functions)
-- Comprehensive documentation
-- Extensive testing
-
----
-
-**Version:** 1.0.0
-**Implementation Date:** 2025-10-06
-**Status:** ✅ Complete
-**Next Review:** 2025-11-06

+#! Template rendering daemon functions
+#!
+#! Provides high-performance Jinja2 template rendering via HTTP API.

+#! spawning a new Nushell process for each template render.
+#!
+#! Performance:
+#! - Single render: ~4-10ms (vs ~500ms with Nushell spawning)
+#! - Batch 10 renders: ~50-60ms (vs ~5500ms)
+#! - Batch 100 renders: ~600-700ms (vs ~55000ms)

+# * `context` - Context record with template variables
+# * `--name` - Optional template name for error reporting

+# Module: Service Availability Check Utilities
+# Purpose: Reusable patterns for checking service availability before making requests
+# Guidelines: Follows .claude/guidelines/provisioning.md - Service Check Pattern
+#
+# Features:
+# - Check individual service availability
+# - Check all essential services (cascade failure detection)
+# - Check external dependencies (database, OCI registries, Git sources)
+# - Clean error messages with short aliases
+# - No stack traces (uses print + return, not error make)
+
+# Selective imports (ADR-025 Phase 3 Layer 2).

+# Cómo Agregar un Nuevo Comando
+
+**Sistema actual**: Los comandos se definen en `commands-registry.ncl` y se dispatch dinámicamente.
+
+## Pasos para Agregar un Comando
+
+### 1. Agregar a commands-registry.ncl
+
+```nickel
+make_command {
+  command = "mi-comando",
+  aliases = ["mi", "cmd"],
+  help_category = "mi-categoria",  # ← Este es el domain
+  description = "Descripción del comando"
+}
+```
+
+### 2. Crear módulo de handler (SI es nueva categoría)
+
+Si `help_category = "mi-categoria"` es **nueva**, crear:
+
+```bash
+# Archivo: provisioning/core/nulib/main_provisioning/commands/mi_categoria.nu
+
+export def handle_mi_categoria_command [
+  command: string
+  ops: string
+  flags: record
+] {
+  match $command {
+    "subcomando1" => { # implementar lógica aquí }
+    "subcomando2" => { # implementar lógica aquí }
+    _ => { print $"Unknown command: ($command)" }
+  }
+}
+```
+
+### 3. Importar en dispatcher.nu (SI es nueva categoría)
+
+```nushell
+# Línea ~20
+use commands/mi_categoria.nu *
+```
+
+### 4. Agregar handler al registry (SI es nueva categoría)
+
+```nushell
+# Línea ~245 en handlers record
+let handlers = {
+  infrastructure: {|cmd, ops, flags| handle_infrastructure_command $cmd $ops $flags}
+  orchestration: {|cmd, ops, flags| handle_orchestration_command $cmd $ops $flags}
+  mi-categoria: {|cmd, ops, flags| handle_mi_categoria_command $cmd $ops $flags}
+}
+```
+
+## Comandos en Categoría Existente
+
+Si `help_category` usa una categoría existente (e.g., "infrastructure"), **solo** actualizar:
+
+1. `commands-registry.ncl` (paso 1)
+2. El handler correspondiente (e.g., `commands/infrastructure.nu`)
+
+**No** necesitas tocar dispatcher.nu.
+
+## Resultado
+
+✅ **1 archivo** para comando en categoría existente
+✅ **3 archivos** para nueva categoría completa

+# Core Provisioning Scripts
+
+Reusable Nushell scripts for querying system state, validation, and metadata extraction.
+
+## Purpose
+
+These scripts provide a clean interface for:
+- **Querying** system resources (providers, servers, clusters, etc.)
+- **Validating** system state (commands, configuration)
+- **Extracting** metadata (help categories, schema info)
+
+## Usage Contexts
+
+1. **Bash wrapper** (`provisioning/core/cli/provisioning`)
+2. **CLI commands** (via dispatcher and command handlers)
+3. **Direct invocation** (for debugging, testing, CI/CD)
+4. **Other scripts** (as utilities)
+
+## Scripts
+
+### Query Scripts (Read-only resource listing)
+
+| Script | Purpose | Usage |
+| ------ | ------- | ----- |
+| `query-providers.nu` | List all available providers | `nu query-providers.nu` |
+| `query-taskservs.nu` | List all available taskservs | `nu query-taskservs.nu` |
+| `query-servers.nu` | List servers in active workspace | `nu query-servers.nu [infra_filter]` |
+| `query-clusters.nu` | List clusters in active workspace | `nu query-clusters.nu` |
+| `query-infra.nu` | List infrastructures in active workspace | `nu query-infra.nu` |
+
+**Output**: Table format (columns: name, type, status, etc.)
+
+### Validation Scripts
+
+| Script | Purpose | Usage |
+| ------ | ------- | ----- |
+| `validate-command.nu` | Validate if command exists in registry | `nu validate-command.nu <command_name>` |
+| `validate-config.nu` | Validate configuration structure | `nu validate-config.nu` |
+
+**Output**:
+- `validate-command.nu`: `FOUND|true/false` or `NOT_FOUND`
+- `validate-config.nu`: Validation errors or success message
+
+### Metadata Scripts
+
+| Script | Purpose | Usage |
+| ------ | ------- | ----- |
+| `get-help-category.nu` | Get help category for command | `nu get-help-category.nu <schema_file> <command>` |
+
+**Output**: Help category string or empty
+
+## Design Principles
+
+1. ✅ **Single responsibility**: Each script does ONE thing
+2. ✅ **Reusable**: Can be called from any context
+3. ✅ **Testable**: Can run standalone with `nu --ide-check`
+4. ✅ **Self-contained**: Minimal dependencies (lib_minimal.nu when needed)
+5. ✅ **Structured output**: Consistent format for bash consumption
+
+## Naming Convention
+
+- `query-*.nu`: Read-only resource listing
+- `validate-*.nu`: System state validation
+- `get-*.nu`: Metadata extraction
+
+## Guidelines
+
+- Use `do { } | complete` pattern for error handling
+- All scripts should be executable (`chmod +x`)
+- Use `#!/usr/bin/env nu` shebang
+- Source `lib_minimal.nu` when workspace functions needed
+- Return structured output (table, string, or status code)
+- No side effects (read-only operations)
+
+## Testing
+
+```bash
+# Syntax validation
+nu --ide-check 50 query-providers.nu
+
+# Functional testing
+nu query-providers.nu
+nu validate-command.nu platform
+nu get-help-category.nu "$PROVISIONING/core/nulib/commands-registry.ncl" guides
+```
+
+## Migration from init-wrapper
+
+These scripts were previously in `provisioning/core/cli/init-wrapper/` with different names:
+- `provider-list.nu` → `query-providers.nu`
+- `taskserv-list.nu` → `query-taskservs.nu`
+- `server-list.nu` → `query-servers.nu`
+- `cluster-list.nu` → `query-clusters.nu`
+- `infra-list.nu` → `query-infra.nu`
+- `validate-command.nu` → (same name)
+- `validate-config.nu` → (same name)
+- `get-help-category.nu` → (same name)
+
+The new location (`core/nulib/scripts/`) reflects their general-purpose nature beyond just bash wrapper initialization.

-# Test Environment Service - Implementation Summary
-
-**Date**: 2025-10-06
-**Status**: ✅ Complete and Production Ready
-
----
-
-## 🎯 What Was Built
-
-A complete **containerized test environment service** integrated into the orchestrator, enabling automated testing of:
-- Single taskservs
-- Complete servers with multiple taskservs
-- Multi-node cluster topologies (Kubernetes, etcd, etc.)
-
-### Key Innovation
-**No manual Docker management** - The orchestrator automatically handles:
-- Container lifecycle
-- Network isolation
-- Resource limits
-- Multi-node topologies
-- Test execution
-- Cleanup
-
----
-
-## 📦 Implementation Details
-
-### Rust Components (Orchestrator)
-
-#### 1. **test_environment.rs** - Core Types
-- Test environment types: Single/Server/Cluster
-- Resource limits configuration
-- Network configuration
-- Container instances
-- Test results tracking
-
-#### 2. **container_manager.rs** - Docker Integration
-- Docker API client (bollard)
-- Container lifecycle management
-- Network creation/isolation
-- Image pulling
-- Command execution
-- Log collection
-
-#### 3. **test_orchestrator.rs** - Orchestration
-- Environment provisioning logic
-- Single taskserv setup
-- Server simulation
-- Cluster topology deployment
-- Test execution framework
-- Cleanup automation
-
-#### 4. **API Endpoints** (main.rs)
-```

-GET    /test/environments
-GET    /test/environments/{id}
-POST   /test/environments/{id}/run
-DELETE /test/environments/{id}
-GET    /test/environments/{id}/logs
-```
-
-### Nushell Integration

-- `test env cluster` - Cluster topology
-- `test env list/get/status` - Management
-- `test env run` - Execute tests
-- `test env logs` - View logs
-- `test env cleanup` - Cleanup
-- `test quick` - One-command test
-
-#### 2. **test/mod.nu** - CLI Dispatcher
-- Command routing
-- Help system
-- Integration with main CLI
-
-#### 3. **CLI Integration**
-- Added to main dispatcher
-- Registry shortcuts: `test`, `tst`
-- Full help documentation
-
-### Configuration & Templates
-
-#### 1. **test-topologies.toml** - Predefined Topologies
-Templates included:
-- `kubernetes_3node` - K8s HA cluster (1 CP + 2 workers)
-- `kubernetes_single` - All-in-one K8s
-- `etcd_cluster` - 3-member etcd cluster
-- `containerd_test` - Standalone containerd
-- `postgres_redis` - Database stack
-
-#### 2. **Cargo.toml** - Dependencies
-- Added `bollard = "0.17"` for Docker API

-## Security Implementation
-
-### 1. Path Interpolation
-
-All paths support secure interpolation:
-```toml
-base = "{{workspace.path}}/.kms"           # Workspace-relative
-keys_dir = "{{kms.paths.base}}/keys"       # Self-referential
-token_path = "{{env.HOME}}/.kms/token"     # Environment-based
-```
-
-**Benefits:**
-- No hardcoded paths
-- Portable configurations
-- Dynamic workspace support
-- Environment-aware
-
-### 2. Secret References
-
-**Never plaintext secrets!** Only references:
-```toml
-# ✅ Secure
-password_secret = "sops://kms/remote/password"
-api_key = "vault://kms/api_key"
-
-# ❌ Insecure (blocked by validation)
-password = "my-password"
-```
-
-**Supported Schemes:**
-- `sops://` - SOPS encrypted
-- `vault://` - HashiCorp Vault
-- `kms://` - KMS encrypted
-- `age://` - Age encrypted
-
-### 3. Permission Enforcement
-
-```toml
-[kms.local.age]
-key_permissions = "0600"  # Owner read/write only
-
-[kms.security]
-enforce_key_permissions = true
-disallow_plaintext_secrets = true
-```
-
-**Enforced Rules:**
-- Keys must be 0600 or 0400
-- Secrets must be references
-- TLS 1.3+ for remote
-- Certificate verification required
-
-### 4. Audit and Monitoring
-
-```toml
-[kms.policies]
-audit_log_enabled = true
-audit_log_path = "{{kms.paths.base}}/audit.log"
-audit_log_format = "json"
-
-[kms.monitoring]
-health_check_enabled = true
-metrics_enabled = true
-```
-
-**Logged Events:**
-- Encryption/decryption operations
-- Key rotations
-- Authentication attempts
-- Configuration changes
-
-## Changes to Existing Code
-
-### Modified Files
-
-#### 1. config/accessor.nu
-
-**Location:** `/provisioning/core/nulib/lib_provisioning/config/accessor.nu`
-
-**Changes:**
-- Added 59 new KMS accessor functions (lines 739-1144)
-- Added comprehensive documentation header
-- Added helper function `get-kms-config-full`
-- Total KMS functions: 69 (10 existing + 59 new)
-
-**No Breaking Changes:**
-- Existing functions preserved
-- Backward compatible
-- Additive only
-
-### Existing KMS Library (lib.nu)
-
-**Location:** `/provisioning/core/nulib/lib_provisioning/kms/lib.nu`
-
-**Current State:**
-- Uses old accessor functions (`get-kms-server`, etc.)
-- Hardcoded to remote KMS (Cosmian)
-- No local/hybrid mode support
-
-**Recommended Updates:**
-```nushell
-# Update get_kms_config function to use new accessors:
-def get_kms_config [] {
-    let mode = (get-kms-mode)
-
-    match $mode {
-        "local" => {
-            {
-                provider: (get-kms-local-provider)
-                key_path: (get-kms-local-key-path)
-            }
-        }
-        "remote" => {
-            {
-                endpoint: (get-kms-remote-endpoint)
-                auth_method: (get-kms-remote-auth-method)
-                # ... existing remote config
-            }
-        }
-        "hybrid" => {
-            # Both configs with fallback
-        }
-    }
-}
-```
-
-**Note:** lib.nu was NOT modified in this task. Future task should update it to use new config.
-
-## Integration Points
-
-### 1. With SOPS
-
-KMS config is now independent but still supports SOPS:
-```toml
-[kms.local]
-provider = "sops"
-sops_config = "{{workspace.path}}/.sops.yaml"
-
-[kms.local.sops]
-age_recipients = ["age1xxx..."]
-```
-
-### 2. With Workspace Config
-
-KMS config loads from workspace:
-```toml
-[kms.paths]
-base = "{{workspace.path}}/.kms"
-```
-
-### 3. With Provider Configs
-
-Can integrate with cloud provider KMS:
-```toml
-[kms.local.sops]
-aws_kms_arn = "arn:aws:kms:..."
-gcp_kms_resource_id = "projects/..."
-azure_keyvault_url = "https://..."
-```
-
-## Usage Examples
-
-### Local Age Encryption
-```nushell
-# Configuration automatically loaded
-let kms_config = (get-kms-config-full)
-print $kms_config.local.key_path
-# Output: /workspace/my-project/.kms/keys/age.txt
-```
-
-### Remote KMS with mTLS
-```nushell
-let endpoint = (get-kms-remote-endpoint)
-let auth = (get-kms-remote-auth-method)
-let tls_enabled = (get-kms-remote-tls-enabled)
-
-print $"Connecting to ($endpoint) using ($auth)"
-# Output: Connecting to https://kms.prod.example.com using mtls
-```
-
-### Hybrid Mode with Fallback
-```nushell
-let mode = (get-kms-mode)
-let fallback = (get-kms-hybrid-fallback-to-local)
-
-if $mode == "hybrid" and $fallback {
-    print "Hybrid mode with local fallback enabled"
-}
-```
-
