- fetch_format_rules.py CLI: robots.txt-aware fetcher (httpx + bs4,
>=2s per-host throttle) + DeepSeek quote-backed rule extractor
- Status: OUP/Wiley/Cell return 403 from this environment; the five
featured journals' format_rules in journals.json were manually
verified against official sites instead. Tooling kept for future
re-runs; data/format_cache/ is runtime output and gitignored
- Service code never imports this toolchain (standalone CLI only)
