"""
Generate spec/index.md from spec/tasks/*.md
Assumptions:
- Each task file starts with YAML-like front matter:
---
id: 001
title: Add endpoint /reports/addons
status: TODO # TODO | DONE
created: 2026-02-01
---
Notes:
- status lives inside each task file (as requested).
- index.md is fully overwritten and marked as generated.
- No external deps (no PyYAML). Supports simple "key: value" scalars.
Usage:
python3 spec/gen_spec_index.py
python3 spec/gen_spec_index.py --check # verify index is up-to-date (CI)
