## 📂 Session Structure

Both versions create identical session structure:

```
.workflow/.execution/{executionId}/
├── execution.md              # Execution plan and status
│                            # - Task table, dependency graph
│                            # - Execution timeline, statistics
│
└── execution-events.md       # SINGLE SOURCE OF TRUTH
                             # - All agent executions (chronological)
                             # - Success/failure with details
                             # - Artifacts and notes for next agent
```

**Generated files**:
- Created at project paths: `src/types/auth.ts` (not `artifacts/src/types/auth.ts`)
- execution-events.md records actual paths for reference

## 🚀 Execution Flow

```
1. Load & Parse Plan
   ├─ Detect plan format
   ├─ Extract tasks
   └─ Validate dependencies

2. Session Setup
   ├─ Create execution folder
   ├─ Initialize execution.md
   └─ Initialize execution-events.md

3. Pre-Execution Validation
   ├─ Check task feasibility
   ├─ Detect dependency cycles
   └─ User confirmation (unless auto-confirm)

4. Execution Orchestration
   ├─ Topological sort
   ├─ Group into waves (parallel-safe)
   ├─ Execute wave by wave
   └─ Track progress in real-time

5. Progress Logging
   ├─ Each agent reads all previous executions
   ├─ Agent executes with full context
   ├─ Agent appends event (success/failure)
   └─ Next agent inherits complete history

6. Completion
   ├─ Collect statistics
   ├─ Update execution.md
   ├─ execution-events.md complete
   └─ Offer follow-up options
```

## 🎯 Design Principles

1. **Single Source of Truth**
   - execution-events.md as unified execution log
   - No redundant tracking systems

2. **Knowledge Chain**
   - Each agent reads all previous executions
   - Context automatically inherited
   - Full visibility into dependencies

3. **Format Agnostic**
   - Accepts any planning/brainstorm/analysis output
   - Smart format detection
   - Extensible parser architecture

4. **Incremental Progress**
   - No re-execution of completed tasks
   - Resume from failure points
   - Session persistence

5. **Safety & Visibility**
   - Append-only event logging
   - No data loss on failure
   - Detailed error recovery
   - Complete execution timeline

## 🔧 When to Use Each Version

### Use Claude Version When:
- Running in Claude Code CLI environment
- Need direct tool integration (TodoWrite, Task, AskUserQuestion)
- Prefer CLI flag syntax (`-y`, `-p`, `-m`)
- Building multi-command workflows
- Want full workflow system integration

### Use Codex Version When:
- Executing directly in Codex
- Prefer variable substitution format
- Need standalone execution
- Integrating with Codex command chains
- Want simpler parameter interface

---
