+ AgentiCorp: Cost tracking (analytics only)
+ Key Differentiators
+
+ VAPORA advantages:
+ - Learning curves: Agents improve via execution history with recency bias
+ - Cost-aware routing: Automatic fallback to cheaper providers when budget
+ exceeded
+ - Knowledge Graph: Temporal execution history with causal reasoning +
+ similarity search
+ - Type safety: Full Rust stack with compile-time guarantees
+ - Swarm coordination: Prometheus metrics, capability-based filtering
+
+ AgentiCorp advantages:
+ - Temporal integration: Battle-tested workflow durability (saga patterns,
+ retries, timeouts)
+ - Simpler deployment: Single Docker Compose brings up entire stack
+ - Human-in-the-loop: Built-in decision/approval workflows with 48h timeouts
+ - Self-improvement: Meta-circular "agenticorp" persona that enhances the
+ platform
+ - Lower barrier: Go is more accessible than async Rust
+
+ Architecture Philosophy
+
+ VAPORA: Fine-grained crates, explicit boundaries, compile-time safety
+ └── 13 crates, 218+ tests, typed errors, trait-based abstractions
+
+ AgentiCorp: Coarse-grained Go packages, runtime flexibility, Temporal

+ ★ Insight ─────────────────────────────────────
+ Workflow durability: AgentiCorp's Temporal dependency provides battle-tested
+ saga patterns, automatic retries, and complete audit trails—features that
+ VAPORA implements manually via NATS + custom coordinator logic.
+
+ Learning vs Personas: VAPORA's learning profiles adapt agent selection based
+ on historical performance; AgentiCorp uses static personas mimicking org
+ structures (CEO, PM, QA). Different paradigms: adaptive ML vs human org
+ simulation.
+
+ Cost control philosophy: VAPORA enforces budgets at routing time (prevent
+ overspend); AgentiCorp tracks costs after-the-fact (analytics). Proactive vs
+ reactive.
+ ─────────────────────────────────────────────────
+
+ Recommendation
+
+ - Use VAPORA if you need: type safety, multi-provider LLM routing with budget
+ enforcement, learning-based agent selection, or a full-Rust stack.
+ - Use AgentiCorp if you need: quick deployment, Temporal's workflow
+ guarantees, human approval workflows, or Go ecosystem familiarity.

+ ★ Insight ─────────────────────────────────────
+ Complementariedad: Los tres proyectos no compiten—operan en capas distintas:
+ - TypeDialog = Input/Output layer (recolección estructurada)
+ - VAPORA = Intelligence layer (decisiones, aprendizaje, routing)
+ - Provisioning = Execution layer (infraestructura real)
+
+ Diferenciador común: Stack 100% Rust/Nushell/Nickel sin dependencias
+ Python/Node. Type safety desde config hasta deployment.
+
+ Oportunidad de integración: VAPORA podría invocar TypeDialog para inputs
+ interactivos y Provisioning para ejecución, creando un pipeline end-to-end
+ declarativo.

+
+ ★ Insight ─────────────────────────────────────
+ axum vs axum-server: Son crates diferentes. axum::serve es la API oficial
+ desde Axum 0.7+ y maneja HTTP/1.1 y HTTP/2 nativamente. axum-server era un
+ wrapper externo que añadía TLS y graceful shutdown, pero su mantenimiento no
+ sigue el ritmo de hyper/hyper-util.
+
+ TLS nativo: Con tokio-rustls puedes implementar TLS directamente con
+ TlsAcceptor sobre el listener antes de pasarlo a axum::serve. Es más explícito
+ y evita dependencias intermedias problemáticas.

+ Archivo: Cargo.toml
+ Cambio: Eliminado axum-server, añadido tokio-rustls
+ ────────────────────────────────────────
+ Archivo: crates/vapora-backend/Cargo.toml
+ Cambio: Eliminado axum-server
+ 2. Fix del test test_step_execution_updates_timestamps
+ Archivo: crates/vapora-agents/src/coordinator.rs
+ Cambio: Nueva función resolve_schema_dir()
+ Causa raíz: El ValidationPipeline usaba path relativo schemas/ que fallaba
+ cuando los tests ejecutaban desde el directorio del crate.
+
+ Solución: Función que busca el directorio schemas/ con esta prioridad:
+ 1. VAPORA_SCHEMA_DIR env var (si es absoluto)
+ 2. Traverse up desde CARGO_MANIFEST_DIR buscando schemas/
+ 3. current_dir()/schemas
+ 4. Fallback a schemas/ relativo
+
+ fn resolve_schema_dir() -> PathBuf {
+ // Check env var first
+ if let Ok(dir) = std::env::var("VAPORA_SCHEMA_DIR") { ... }
+
+ // Try to find workspace root from CARGO_MANIFEST_DIR
+ if let Ok(manifest_dir) = std::env::var("CARGO_MANIFEST_DIR") {
+ // Traverse up looking for schemas/ directory
+ }
+ ...
+ }
+
+ Resultado:
+ ✅ cargo check --workspace → Finished
+ ✅ cargo test --workspace --lib → All 218+ tests pass
+
+ ★ Insight ─────────────────────────────────────
+ Path resolution en Cargo workspaces: Los tests de crates individuales ejecutan
+ con cwd en el directorio del crate, no en el workspace root.
+ CARGO_MANIFEST_DIR siempre apunta al Cargo.toml del crate actual, permitiendo
+ navegar hacia arriba para encontrar recursos del workspace.
+
+ axum-server vs axum::serve: axum-server es un wrapper de terceros que añade
+ TLS/graceful shutdown. Desde Axum 0.7, axum::serve es suficiente para la
+ mayoría de casos. TLS se puede añadir con tokio-rustls directamente sobre el
+ TcpListener.

+ Key Differentiators
+
+ VAPORA advantages:
+ - Learning curves: Agents improve via execution history with recency bias
+ - Cost-aware routing: Automatic fallback to cheaper providers when budget
+ exceeded
+ - Knowledge Graph: Temporal execution history with causal reasoning +
+ similarity search
+ - Type safety: Full Rust stack with compile-time guarantees
+ - Swarm coordination: Prometheus metrics, capability-based filtering
+
+ AgentiCorp advantages:
+ - Temporal integration: Battle-tested workflow durability (saga patterns,
+ retries, timeouts)
+ - Simpler deployment: Single Docker Compose brings up entire stack
+ - Human-in-the-loop: Built-in decision/approval workflows with 48h timeouts
+ - Self-improvement: Meta-circular "agenticorp" persona that enhances the
+ platform
+ - Lower barrier: Go is more accessible than async Rust
+
+ Architecture Philosophy
+
+ VAPORA: Fine-grained crates, explicit boundaries, compile-time safety

+ ★ Insight ─────────────────────────────────────
+ Workflow durability: AgentiCorp's Temporal dependency provides battle-tested
+ saga patterns, automatic retries, and complete audit trails—features that
+ VAPORA implements manually via NATS + custom coordinator logic.
+
+ Learning vs Personas: VAPORA's learning profiles adapt agent selection based
+ on historical performance; AgentiCorp uses static personas mimicking org
+ structures (CEO, PM, QA). Different paradigms: adaptive ML vs human org
+ simulation.
+
+ Cost control philosophy: VAPORA enforces budgets at routing time (prevent
+ overspend); AgentiCorp tracks costs after-the-fact (analytics). Proactive vs
+ reactive.
+ ─────────────────────────────────────────────────
+
+ Recommendation
+
+ - Use VAPORA if you need: type safety, multi-provider LLM routing with budget
+ enforcement, learning-based agent selection, or a full-Rust stack.
+ - Use AgentiCorp if you need: quick deployment, Temporal's workflow
+ guarantees, human approval workflows, or Go ecosystem familiarity.

+ ★ Insight ─────────────────────────────────────
+ Complementariedad: Los tres proyectos no compiten—operan en capas distintas:
+ - TypeDialog = Input/Output layer (recolección estructurada)
+ - VAPORA = Intelligence layer (decisiones, aprendizaje, routing)
+ - Provisioning = Execution layer (infraestructura real)
+
+ Diferenciador común: Stack 100% Rust/Nushell/Nickel sin dependencias
+ Python/Node. Type safety desde config hasta deployment.
+
+ Oportunidad de integración: VAPORA podría invocar TypeDialog para inputs
+ interactivos y Provisioning para ejecución, creando un pipeline end-to-end
+ declarativo.

+ Archivo: crates/vapora-backend/Cargo.toml
+ Cambio: Eliminado axum-server
+ 2. Fix del test test_step_execution_updates_timestamps
+ Archivo: crates/vapora-agents/src/coordinator.rs
+ Cambio: Nueva función resolve_schema_dir()
+ Causa raíz: El ValidationPipeline usaba path relativo schemas/ que fallaba
+ cuando los tests ejecutaban desde el directorio del crate.
+
+ Solución: Función que busca el directorio schemas/ con esta prioridad:
+ 1. VAPORA_SCHEMA_DIR env var (si es absoluto)
+ 2. Traverse up desde CARGO_MANIFEST_DIR buscando schemas/
+ 3. current_dir()/schemas
+ 4. Fallback a schemas/ relativo
+
+ fn resolve_schema_dir() -> PathBuf {
+ // Check env var first
+ if let Ok(dir) = std::env::var("VAPORA_SCHEMA_DIR") { ... }
+
+ // Try to find workspace root from CARGO_MANIFEST_DIR
+ if let Ok(manifest_dir) = std::env::var("CARGO_MANIFEST_DIR") {
+ // Traverse up looking for schemas/ directory
+ }
+ ...
+ }
+
+ Resultado:
+ ✅ cargo check --workspace → Finished
+ ✅ cargo test --workspace --lib → All 218+ tests pass
+
+ ★ Insight ─────────────────────────────────────
+ Path resolution en Cargo workspaces: Los tests de crates individuales ejecutan
+ con cwd en el directorio del crate, no en el workspace root.
+ CARGO_MANIFEST_DIR siempre apunta al Cargo.toml del crate actual, permitiendo
+ navegar hacia arriba para encontrar recursos del workspace.
+
+ axum-server vs axum::serve: axum-server es un wrapper de terceros que añade
+ TLS/graceful shutdown. Desde Axum 0.7, axum::serve es suficiente para la
+ mayoría de casos. TLS se puede añadir con tokio-rustls directamente sobre el
+ TcpListener.

- **Smart Organization**: Feature tags, priority levels, task ordering
- **Responsive Design**: Works seamlessly from mobile to ultra-wide displays
+### 🔄 Workflow Orchestrator (v1.2.0)
+
+- **Multi-Stage Pipelines**: Orchestrate complex workflows with approval gates
+- **Short-Lived Agent Contexts**: 95% cache token reduction (from $840/month to $110/month)
+- **Artifact Passing**: ADR, Code, TestResults, Review, Documentation artifacts between stages
+- **Kogral Integration**: Automatic context enrichment from `.kogral/` filesystem (guidelines, patterns, ADRs)
+- **CLI Management**: 6 commands (start, list, status, approve, cancel, templates)
+- **Event-Driven Coordination**: NATS pub/sub for workflow stage progression
+- **4 Workflow Templates**:
+ - `feature_development` (5 stages: design → implementation → testing → review → deployment)
+ - `bugfix` (4 stages: investigation → fix → testing → deployment)
+ - `documentation_update` (3 stages: creation → review → publish)
+ - `security_audit` (4 stages: analysis → testing → remediation → verification)
+
### 🧠 Intelligent Learning & Cost Optimization (Phase 5.3 + 5.4)
- - **Per-Task-Type Learning**: Agents build expertise profiles from execution history
- - **Recency Bias**: Recent performance weighted 3x (last 7 days) for adaptive selection
- - **Budget Enforcement**: Hard caps per role (monthly/weekly) with automatic fallback
- - **Cost-Efficient Routing**: Quality/cost ratio optimization for provider selection
- - **Learning Curves**: Track agent improvement over time with confidence scoring
- - **Prometheus Metrics**: Real-time budget utilization, fallback triggers, cost per provider
- - **Gradual Production Rollout**: 4-week canary deployment with automated rollback

+//! Vapora Workflow Engine
+//!
+//! Orchestrates multi-stage workflows with learning-based agent selection,
+//! artifact passing between stages, and cost-aware LLM routing.
+//!
+//! # Architecture
+//!
+//! The workflow engine uses a state machine approach where each
+//! WorkflowInstance tracks progress through stages. Each stage can execute
+//! tasks in parallel or sequentially, with artifacts passed between stages via
+//! the Knowledge Graph.
+//!
+//! # Key Components
+//!
+//! - `WorkflowOrchestrator`: Main coordinator managing workflow lifecycle
+//! - `WorkflowInstance`: State machine tracking individual workflow execution
+//! - `StageState`: Manages stage execution and task assignment
+//! - `Artifact`: Data passed between stages
+//!
+//! # Example
+//!
+//! ```no_run
+//! use vapora_workflow_engine::{WorkflowOrchestrator, config::WorkflowsConfig};
+//! use std::sync::Arc;
+//!
+//! # async fn example() -> Result<(), Box> {
+//! // Initialize dependencies (SwarmCoordinator, KGPersistence, NATS)
+//! # let swarm = todo!();
+//! # let kg = todo!();
+//! # let nats = todo!();
+//!
+//! // Create orchestrator
+//! let orchestrator = Arc::new(
+//! WorkflowOrchestrator::new(
+//! "config/workflows.toml",
+//! swarm,
+//! kg,
+//! nats,
+//! ).await?
+//! );
+//!
+//! // Start event listener
+//! orchestrator.clone().start_event_listener().await?;
+//!
+//! // Start a workflow
+//! let workflow_id = orchestrator.start_workflow(
+//! "feature_development",
+//! serde_json::json!({
+//! "task": "Add authentication",
+//! "requirements": ["OAuth2", "JWT"]
+//! })
+//! ).await?;

+# ADR-0028: Workflow Orchestrator for Cost-Efficient Multi-Agent Pipelines
+
+## Status
+
+**Accepted** - Implemented in v1.2.0
+
+## Context
+
+### The Problem: Excessive LLM Costs from Cache Token Accumulation
+
+Analysis of real Claude Code usage data (5 weeks, individual developer) reveals a critical cost pattern:
+
+| Metric | Value |
+|--------|-------|
+| Total cost | $1,050.68 |
+| Weekly average | ~$210 |
+| Monthly projection | ~$840 |
+| Cache read tokens | 3.82B (95.7% of total) |
+| Cache creation tokens | 170M (4.3%) |
+| Direct input tokens | 2.4M (0.06%) |
+| Direct output tokens | 366K (0.009%) |
+
+**The cost is dominated by cache tokens, not generation.**
+
+### Root Cause: Monolithic Session Pattern
+
+Current workflow with Claude Code follows a monolithic session pattern:
+
+```text
+Session start
+├─ Message 1: context 50K → cache read 50K
+├─ Message 2: context 100K → cache read 100K
+├─ Message 3: context 150K → cache read 150K
+├─ ...
+└─ Message 50: context 800K → cache read 800K
+ ─────────────────
+ ~20M cache reads per session
+```
+
+Each message in a long session re-sends the entire conversation history. Over a typical development session (50+ messages), context accumulates to 500K-1M tokens, with each subsequent message re-transmitting all previous context.
+
+### Why This Matters
+
+At current pricing (2026 rates):
+
+- Cache read (Haiku): $0.03/1M tokens
+- Cache read (Sonnet): $0.30/1M tokens
+- Cache read (Opus): $1.50/1M tokens
+
+With 3.82B cache read tokens distributed across Sonnet (51%) and Haiku (38%), the cache cost alone exceeds what direct input/output would cost.
+
+## Decision
+
+**Implement a Workflow Orchestrator (vapora-workflow-engine) that executes multi-stage pipelines with short-lived agent contexts.**
+
+### Architecture: Agents with Short Lifecycles
+
+Instead of one long session accumulating context, workflows execute as discrete stages:
+
+```text
+┌─────────────────────────────────────────────────────────┐
+│ Task: "Implement feature X" │
+└─────────────────────────────────────────────────────────┘
+ │
+ ┌────────────────────┼────────────────────┐
+ ▼ ▼ ▼
+┌─────────┐ ┌──────────┐ ┌──────────┐
+│Architect│ │Developer │ │ Reviewer │
+│ (Opus) │ │ (Haiku) │ │ (Sonnet) │
+├─────────┤ ├──────────┤ ├──────────┤
+│Context: │ │Context: │ │Context: │
+│ 40K │───────▶│ 25K │───────▶│ 35K │
+│ 5 msgs │ spec │ 12 msgs │ code │ 4 msgs │
+│ 200K │ │ 300K │ │ 140K │
+│ cache │ │ cache │ │ cache │
+└────┬────┘ └────┬─────┘ └────┬─────┘
+ │ │ │
+ ▼ ▼ ▼
+ TERMINATES TERMINATES TERMINATES
+ (context (context (context
+ discarded) discarded) discarded)
+
+Total cache: ~640K
+Monolithic equivalent: ~20-40M
+Reduction: 95-97%
+```
+
+### Key Principles
+
+1. **Context isolation**: Each agent receives only what it needs (spec, relevant files), not full conversation history
+
+2. **Artifact passing, not conversation passing**: Between agents flows the result (spec, code, review), not the dialogue that produced it
+
+3. **Short lifecycles**: Agent completes task → context dies → next agent starts fresh
+
+4. **Persistent memory via Kogral**: Important decisions/patterns stored in knowledge base, not in session context
+
+## Implementation
+
+### Components
+
+1. **vapora-workflow-engine** (new crate):
+ - `WorkflowOrchestrator`: Main coordinator managing workflow lifecycle
+ - `WorkflowInstance`: State machine tracking individual workflow execution
+ - `StageState`: Manages stage execution and task assignment
+ - `Artifact`: Data passed between stages (ADR, Code, TestResults, Review, Documentation)
+
+2. **Workflow Templates** (`config/workflows.toml`):
+ - `feature_development` (5 stages): architecture → implementation → testing → review → deployment
+ - `bugfix` (4 stages): investigation → fix → testing → deployment
+ - `documentation_update` (3 stages): content → review → publish
+ - `security_audit` (4 stages): analysis → pentesting → remediation → verification
+
+3. **REST API** (`/api/v1/workflow_orchestrator`):
+ - `POST /` - Start workflow
+ - `GET /` - List active workflows
+ - `GET /:id` - Get workflow status
+ - `POST /:id/approve` - Approve waiting stage
+ - `POST /:id/cancel` - Cancel running workflow
+ - `GET /templates` - List available templates
+
+4. **CLI** (vapora-cli):
+ - `vapora workflow start --template --context context.json`
+ - `vapora workflow list`
+ - `vapora workflow status `
+ - `vapora workflow approve --approver "Name"`
+ - `vapora workflow cancel --reason "Reason"`
+ - `vapora workflow templates`
+
+5. **Kogral Integration**:
+ - `enrich_context_from_kogral()` - Loads guidelines, patterns, ADRs
+ - Filesystem-based knowledge retrieval from `.kogral/` directory
+ - Configurable via `KOGRAL_PATH` environment variable
+
+### Integration with Existing Components
+
+| Component | Usage |
+|-----------|-------|
+| SwarmCoordinator | Task assignment via `submit_task_for_bidding()` |
+| AgentRegistry | 12 roles with lifecycle management |
+| LearningProfiles | Expertise-based agent selection |
+| KGPersistence | Workflow execution history |
+| NATS JetStream | Inter-stage event coordination |
+
+## Rationale
+
+### Why Vapora Already Has the Pieces
+
+Current Vapora implementation includes:
+
+| Component | Status | Functionality |
+|-----------|--------|---------------|
+| SwarmCoordinator | Complete | Task assignment, load balancing |
+| AgentRegistry | Complete | 12 roles, lifecycle management |
+| Learning Profiles | Complete | Expertise scoring with recency bias |
+| KG Persistence | Complete | SurrealDB, execution history |
+| NATS Messaging | Complete | Inter-agent communication |
+| Workflow Templates | Complete | `workflows.toml` with stage definitions |
+| Artifact Types | Complete | `TaskCompleted.artifacts` field |
+
+**What was missing**: The orchestration layer that executes workflow templates by loading templates, creating instances, listening for task completions, advancing stages, and passing artifacts.
+
+### Why Not Alternative Solutions
+
+| Alternative | Why Not |
+|-------------|---------|
+| Manual `/compact` in Claude Code | Requires user discipline, doesn't fundamentally change pattern |
+| Shorter sessions manually | Loses context continuity, user must track state |
+| External tools (LiteLLM, CrewAI) | Python-based, doesn't leverage existing Vapora infrastructure |
+| Just use Haiku everywhere | Quality degradation for complex tasks |
+
+Vapora already has budget-aware routing, learning profiles, and swarm coordination. The workflow orchestrator completes the picture.
+
+### Why Kogral Integration
+
+Kogral provides persistent knowledge that would otherwise bloat session context:
+
+| Without Kogral | With Kogral |
+|----------------|-------------|
+| Guidelines re-explained each session | Query once via MCP, inject 5K tokens |
+| ADRs repeated in conversation | Reference by ID, inject summary |
+| Patterns described verbally | Structured retrieval, minimal tokens |
+
+Kogral transforms "remember our auth pattern" (requires context) into "query pattern:auth" (stateless lookup).
+
+## Consequences
+
+### Positive
+
+1. **~95% reduction in cache token costs**: $840/month → ~$50-100/month for same workload
+
+2. **Better model allocation**: Opus for architecture (high quality, few tokens), Haiku for implementation (lower quality acceptable, many tokens)
+
+3. **Leverages existing investment**: Uses SwarmCoordinator, LearningProfiles, KGPersistence already built
+
+4. **Audit trail**: Each agent execution persisted to KG with tokens, cost, duration
+
+5. **Parallelization**: Multiple developers can work simultaneously on different parts
+
+6. **Quality through specialization**: Each agent optimized for its role vs one generalist session
+
+### Negative
+
+1. **Orchestration overhead**: Additional component to maintain
+
+2. **Latency between stages**: Artifact passing adds delay vs continuous conversation
+
+3. **Context loss between agents**: Agent B doesn't know what Agent A "considered but rejected"
+
+4. **Debugging complexity**: Issues span multiple agent executions
+
+### Mitigations
+
+| Negative | Mitigation |
+|----------|------------|
+| Orchestration overhead | Minimal code (~1500 lines), clear separation of concerns |
+| Latency | Parallel stages where possible, async execution |
+| Context loss | Kogral captures decisions, not just outcomes |
+| Debugging | Workflow ID traces all related executions in KG |
+
+## Metrics for Success
+
+| Metric | Before | After (Target) |
+|--------|--------|----------------|
+| Monthly LLM cost | ~$840 | <$150 |
+| Cache tokens per task | ~20M | <1M |
+| Average context size | 500K+ | <50K per agent |
+| Workflow completion rate | N/A | >95% |
+
+## Cost Projection
+
+Based on analyzed usage patterns with optimized workflow:
+
+| Role | Model | % of Work | Monthly Cost |
+|------|-------|-----------|--------------|
+| Architect | Opus | 10% | ~$25 |
+| Developer | Haiku | 50% | ~$30 |
+| Reviewer | Sonnet | 25% | ~$40 |
+| Tester | Haiku | 15% | ~$15 |
+| **Total** | | | **~$110** |
+
+**Savings: ~$730/month (87% reduction)**

+# Workflow Orchestrator
+
+Multi-stage workflow execution with cost-efficient agent coordination and artifact passing.
+
+## Overview
+
+The Workflow Orchestrator (`vapora-workflow-engine`) enables cost-efficient multi-agent pipelines by executing workflows as discrete stages with short-lived agent contexts. Instead of accumulating context in long sessions, agents receive only what they need, produce artifacts, and terminate.
+
+**Key Benefit**: ~95% reduction in LLM cache token costs compared to monolithic session patterns.
+
+## Architecture
+
+### Core Components
+
+```text
+┌─────────────────────────────────────────────────────────┐
+│ WorkflowOrchestrator │
+│ ┌─────────────────────────────────────────────────┐ │
+│ │ WorkflowInstance │ │
+│ │ ├─ workflow_id: UUID │ │
+│ │ ├─ template: WorkflowConfig │ │
+│ │ ├─ current_stage: usize │ │
+│ │ ├─ stage_states: Vec │ │
+│ │ └─ artifacts: HashMap │ │
+│ └─────────────────────────────────────────────────┘ │
+└─────────────────────────────────────────────────────────┘
+ │ │ │
+ ▼ ▼ ▼
+┌──────────┐ ┌──────────┐ ┌──────────┐
+│ NATS │ │ Swarm │ │ KG │
+│ Listener │ │Coordinator│ │Persistence│
+└──────────┘ └──────────┘ └──────────┘
+```
+
+### Workflow Lifecycle
+
+1. **Template Loading**: Read workflow definition from `config/workflows.toml`
+2. **Instance Creation**: Create `WorkflowInstance` with initial context
+3. **Stage Execution**: Orchestrator assigns tasks to agents via SwarmCoordinator
+4. **Event Listening**: NATS subscribers wait for `TaskCompleted`/`TaskFailed` events
+5. **Stage Advancement**: When all tasks complete, advance to next stage
+6. **Artifact Passing**: Accumulated artifacts passed to subsequent stages
+7. **Completion**: Workflow marked complete, metrics recorded
+
+## Workflow Templates
+
+Pre-configured workflows in `config/workflows.toml`:
+
+### feature_development (5 stages)
+
+```toml
+[[workflows]]
+name = "feature_development"
+trigger = "manual"
+
+[[workflows.stages]]
+name = "architecture_design"
+agents = ["architect"]
+parallel = false
+approval_required = false
+
+[[workflows.stages]]
+name = "implementation"
+agents = ["developer", "developer"]
+parallel = true
+max_parallel = 2
+approval_required = false
+
+[[workflows.stages]]
+name = "testing"
+agents = ["tester"]
+parallel = false
+approval_required = false
+
+[[workflows.stages]]
+name = "code_review"
+agents = ["reviewer"]
+parallel = false
+approval_required = true
+
+[[workflows.stages]]
+name = "deployment"
+agents = ["devops"]
+parallel = false
+approval_required = true
+```
+
+**Stages**: architecture → implementation (parallel) → testing → review (approval) → deployment (approval)
+
+### bugfix (4 stages)
+
+**Stages**: investigation → fix → testing → deployment
+
+### documentation_update (3 stages)
+
+**Stages**: content creation → review (approval) → publish
+
+### security_audit (4 stages)
+
+**Stages**: code analysis → penetration testing → remediation → verification (approval)
+
+## Stage Types
+
+### Sequential Stages
+
+Single agent executes task, advances when complete.
+
+```toml
+[[workflows.stages]]
+name = "architecture_design"
+agents = ["architect"]
+parallel = false
+```
+
+### Parallel Stages
+
+Multiple agents execute tasks simultaneously.
+
+```toml
+[[workflows.stages]]
+name = "implementation"
+agents = ["developer", "developer"]
+parallel = true
+max_parallel = 2
+```
+
+### Approval Gates
+
+Stage requires manual approval before advancing.
+
+```toml
+[[workflows.stages]]
+name = "deployment"
+agents = ["devops"]
+approval_required = true
+```
+
+When `approval_required = true`:
+
+1. Workflow pauses with status `waiting_approval:`
+2. NATS event published to `vapora.workflow.approval_required`
+3. Admin approves via API or CLI
+4. Workflow resumes execution
+
+## Artifacts
+
+Data passed between stages:
+
+### Artifact Types
+
+```rust
+pub enum ArtifactType {
+ Adr, // Architecture Decision Record
+ Code, // Source code files
+ TestResults, // Test execution output
+ Review, // Code review feedback
+ Documentation, // Generated docs
+ Custom(String), // User-defined type
+}
+```
+
+### Artifact Flow
+
+```text
+Stage 1: Architecture
+ └─ Produces: Artifact(Adr, "design-spec", ...)
+ │
+ ▼
+Stage 2: Implementation
+ ├─ Consumes: design-spec
+ └─ Produces: Artifact(Code, "feature-impl", ...)
+ │
+ ▼
+Stage 3: Testing
+ ├─ Consumes: feature-impl
+ └─ Produces: Artifact(TestResults, "test-report", ...)
+```
+
+Artifacts stored in `WorkflowInstance.accumulated_artifacts` and passed to subsequent stages via context.
+
+## Kogral Integration
+
+Enrich workflow context with persistent knowledge from Kogral:
+
+```rust
+orchestrator.enrich_context_from_kogral(&mut context, "feature_development").await?;
+```
+
+Loads:
+
+- **Guidelines**: `.kogral/guidelines/{workflow_name}.md`
+- **Patterns**: `.kogral/patterns/*.md` (matching workflow name)
+- **ADRs**: `.kogral/adrs/*.md` (5 most recent, containing workflow name)
+
+Result injected into context:
+
+```json
+{
+ "task": "Add authentication",
+ "kogral_guidelines": {
+ "source": ".kogral/guidelines/feature_development.md",
+ "content": "..."
+ },
+ "kogral_patterns": [
+ { "file": "auth-pattern.md", "content": "..." }
+ ],
+ "kogral_decisions": [
+ { "file": "0005-oauth2-implementation.md", "content": "..." }
+ ]
+}
+```
+
+**Configuration**:
+
+```bash
+export KOGRAL_PATH="/path/to/kogral/.kogral"
+```
+
+Default: `../kogral/.kogral` (sibling directory)
+
+## REST API
+
+All endpoints under `/api/v1/workflow_orchestrator`:

+## NATS Events
+
+Workflow orchestrator publishes/subscribes to NATS JetStream:
+
+### Subscriptions
+
+- `vapora.tasks.completed` - Agent task completion events
+- `vapora.tasks.failed` - Agent task failure events
+
+### Publications
+
+- `vapora.workflow.approval_required` - Stage waiting for approval
+- `vapora.workflow.completed` - Workflow finished successfully
+
+**Event Format**:
+
+```json
+{
+ "type": "approval_required",
+ "workflow_id": "3f9a2b1c-5e7f-4a9b-8c2d-1e3f5a7b9c1d",
+ "stage": "code_review",
+ "timestamp": "2026-01-24T01:45:12.456Z"
+}
+```
+
+## Metrics
+
+Prometheus metrics exposed at `/metrics`:
+
+- `vapora_workflows_started_total` - Total workflows initiated
+- `vapora_workflows_completed_total` - Successfully finished workflows
+- `vapora_workflows_failed_total` - Failed workflows
+- `vapora_stages_completed_total` - Individual stage completions

+- `vapora_workflow_duration_seconds` - Histogram of total workflow times
+
+## Cost Optimization
+
+### Before: Monolithic Session
+
+```text
+Session with 50 messages:
+├─ Message 1: 50K context → 50K cache reads
+├─ Message 2: 100K context → 100K cache reads
+├─ Message 3: 150K context → 150K cache reads
+└─ Message 50: 800K context → 800K cache reads
+ ──────────────────
+ ~20M cache reads
+```
+
+**Cost**: ~$840/month for typical usage
+
+### After: Multi-Stage Workflow
+
+```text
+Workflow with 3 stages:
+├─ Architect: 40K context, 5 msgs → 200K cache reads
+├─ Developer: 25K context, 12 msgs → 300K cache reads
+└─ Reviewer: 35K context, 4 msgs → 140K cache reads
+ ──────────────────
+ ~640K cache reads
+```
+
+**Cost**: ~$110/month for equivalent work
+
+**Savings**: ~$730/month (87% reduction)
+
+## Usage Examples
+
+See [CLI Commands Guide](../setup/cli-commands.md) for command-line usage.
+
+### Programmatic Usage
+
+```rust
+use vapora_workflow_engine::WorkflowOrchestrator;
+use std::sync::Arc;
+
+// Initialize orchestrator
+let orchestrator = Arc::new(
+ WorkflowOrchestrator::new(
+ "config/workflows.toml",
+ swarm,
+ kg,
+ nats,
+ ).await?
+);
+
+// Start event listener
+orchestrator.clone().start_event_listener().await?;
+
+// Start workflow
+let workflow_id = orchestrator.start_workflow(
+ "feature_development",
+ serde_json::json!({
+ "task": "Add authentication",
+ "requirements": ["OAuth2", "JWT"]
+ })
+).await?;
+
+// Get status
+let workflow = orchestrator.get_workflow(&workflow_id)?;
+println!("Status: {:?}", workflow.status);
+
+// Approve stage (if waiting)
+orchestrator.approve_stage(&workflow_id, "Jane Doe").await?;
+```
+
+## Configuration
+
+### Workflow Templates
+
+File: `config/workflows.toml`
+
+```toml
+[engine]
+max_parallel_tasks = 10
+workflow_timeout = 3600
+approval_gates_enabled = true
+
+[[workflows]]
+name = "custom_workflow"
+trigger = "manual"
+
+[[workflows.stages]]
+name = "stage_name"
+agents = ["agent_role"]
+parallel = false
+max_parallel = 1
+approval_required = false
+```
+
+### Environment Variables
+
+```bash
+# Kogral knowledge base path
+export KOGRAL_PATH="/path/to/kogral/.kogral"
+
+# NATS connection
+export NATS_URL="nats://localhost:4222"
+
+# Backend API (for CLI)
+export VAPORA_API_URL="http://localhost:8001"
+```
+
+## Troubleshooting
+
+### Workflow Stuck in "waiting_approval"
+
+**Solution**: Use CLI or API to approve:
+
+```bash
+vapora workflow approve --approver "Your Name"
+```
+
+### Stage Fails Repeatedly
+
+**Check**:
+
+1. Agent availability: `vapora workflow list` (via backend)
+2. NATS connection: Verify NATS URL and cluster status
+3. Task requirements: Check if stage agents have required capabilities
+
+### High Latency Between Stages
+
+**Causes**:
+
+- NATS messaging delay (check network)
+- SwarmCoordinator queue depth (check agent load)
+- Artifact serialization overhead (reduce artifact size)
+
+**Mitigation**:
+
+- Use parallel stages where possible
+- Increase `max_parallel` in stage config
+- Optimize artifact content (references instead of full content)
+
+### Workflow Not Advancing
+
+**Debug**:
+
+```bash
+# Check workflow status
+vapora workflow status
+
+# Check backend logs
+docker logs vapora-backend
+
+# Check NATS messages
+nats sub "vapora.tasks.>"
+```
