VOID Loop — Implementation Checklist (v0.1)

Purpose: Prototype, test, and iterate quickly. Build a runnable module with logs.

0) Meta

• Module:
• Owner:

• Repo/Path:
• Spec link (PRD):

1) Setup

• ☐ .env.example committed (no secrets)
• ☐ Config via env/params (no hard‑coding)
• ☐ requirements.txt / pyproject.toml present
• ☐ Repro seed for stochastic steps (if any)

2) Deterministic pipeline

• ☐ Steps documented in README.md
• ☐ Input validation (schema checks)
• ☐ Output schema enforced (contract)

3) Tests

• ☐ Smoke tests (I/O sanity)
• ☐ Minimal unit tests for core transforms
• ☐ Test dataset available

4) Observability

• ☐ Timing metrics (per step)
• ☐ Error handling with clear messages
• ☐ Usage logs (runs, params)
• ☐ Cost tracking (if APIs/LLMs)

5) Artifacts

• ☐ CLI entry point or notebook
• ☐ Example command(s) in README
• ☐ Sample input/output files

6) Ship v0.1

• ☐ Meets acceptance criteria (see PRD)
• ☐ Tag release v0.1
• ☐ Handover notes

Pitfalls: Over‑engineering v1; skipping tests; no logs.
