# Team IterDev -- CSV Schema

## Master CSV: tasks.csv

### Column Definitions

#### Input Columns (Set by Decomposer)

| Column | Type | Required | Description | Example |
|--------|------|----------|-------------|---------|
| `id` | string | Yes | Unique task identifier | `"DEV-001"` |
| `title` | string | Yes | Short task title | `"Implement design"` |

| `role` | string | Yes | Worker role: architect, developer, tester, reviewer | `"developer"` |
| `pipeline` | string | Yes | Pipeline mode: patch, sprint, multi-sprint | `"sprint"` |
| `sprint_num` | integer | Yes | Sprint number (1-based, for multi-sprint tracking) | `"1"` |
| `gc_round` | integer | Yes | Generator-Critic round number (0 = initial, 1+ = fix round) | `"0"` |
| `deps` | string | No | Semicolon-separated dependency task IDs | `"DESIGN-001"` |
| `context_from` | string | No | Semicolon-separated task IDs for context | `"DESIGN-001"` |
| `exec_mode` | enum | Yes | Execution mechanism: `csv-wave` or `interactive` | `"csv-wave"` |

#### Computed Columns (Set by Wave Engine)

| Column | Type | Description | Example |
|--------|------|-------------|---------|
| `wave` | integer | Wave number (1-based, from topological sort) | `2` |
| `prev_context` | string | Aggregated findings from context_from tasks (per-wave CSV only) | `"[Task DESIGN-001] Created design with 3 components..."` |

#### Output Columns (Set by Agent)

|--------|------|-------------|---------|
| `status` | enum | `pending` -> `completed` / `failed` / `skipped` | `"completed"` |
| `findings` | string | Key discoveries (max 500 chars) | `"Implemented 5 files, all syntax clean..."` |

### exec_mode Values

| Value | Mechanism | Description |
|-------|-----------|-------------|
| `csv-wave` | `spawn_agents_on_csv` | One-shot batch execution within wave |
| `interactive` | `spawn_agent`/`wait`/`send_input`/`close_agent` | Multi-round individual execution |

Interactive tasks appear in master CSV for dependency tracking but are NOT included in wave-{N}.csv files.

## Output Schema (JSON)

Agent output via `report_agent_job_result` (csv-wave tasks):

```json
{
  "id": "DEV-001",
  "status": "completed",
  "findings": "Implemented 5 files following design. All syntax checks pass. Key changes: src/auth/jwt.ts, src/middleware/auth.ts.",
  "review_score": "",
  "gc_signal": "",
  "error": ""
}
```

Reviewer-specific output:

```json
{
  "id": "REVIEW-001",
  "status": "completed",
  "findings": "Reviewed 5 files. Correctness: 8/10, Completeness: 9/10, Maintainability: 7/10, Security: 6/10. 1 HIGH issue (missing token expiry check).",
  "review_score": "7.5",
  "gc_signal": "REVISION_NEEDED",
  "error": ""
}
```

Interactive tasks output via structured text or JSON written to `interactive/{id}-result.json`.

```

> Both csv-wave and interactive agents read/write the same discoveries.ndjson file.

## Cross-Mechanism Context Flow

| Source | Target | Mechanism |
|--------|--------|-----------|
| CSV task findings | Interactive task | Injected via spawn message or send_input |
| Interactive task result | CSV task prev_context | Read from interactive/{id}-result.json |
| Any agent discovery | Any agent | Shared via discoveries.ndjson |
