Always-current corpus for rbi-source-mcp — the indexed RBI regulatory document database (hybrid FTS5 + sqlite-vec retrieval).

This release is a moving alias. Assets are clobber-replaced on every successful build. Consumers polling here never see a 404 window.

Cadence

  • Daily at 02:00 UTC: incremental diff build; ~5 min, ~50 CF Neurons.
  • Monthly on the 1st at 03:00 UTC: full rebuild; ~30 min, ~3000 CF Neurons. Catches silent RBI re-uploads (PDFs replaced without bumping the list-page date) that diff-mode can't see by definition.

Install

pip install rbi-source-mcp
rbi-source-fetch-corpus                   # pulls THIS alias
rbi-source-fetch-corpus --verify-sigstore # cryptographic verify

Verify

  • SHA256: shasum -a 256 -c corpus.sqlite.xz.sha256
  • Sigstore: the .sigstore.json bundles are signed by corpus-release.yml@refs/heads/main via GitHub Actions OIDC.

Smoke gate

Each build passes a paired eval gate before publish:

  • absolute: ≥80% hit-rate on the eval suite
  • regression: <5pp drop vs the prior latest-corpus build

Eval JSON attached as eval.json (used by the next run's regression check) plus eval-current.json (this run's snapshot for forensics).

Forensics on prior corpora

Per-build provenance for this corpus is stamped inside the SQLite at corpus_meta (key/value rows: build_commit, build_run_id, build_mode, embedding_*, schema_version). For older builds: see this workflow's run history — each run carries a 30-day artifact with the corpus + eval.
