SHA256SUMS.txt sat beside the artifacts it vouches for, so whoever could
rewrite a release rewrote the list with it. The packs were already
reproducible, which answers corruption and lets a third party rebuild an
archive byte for byte; nothing answered a rewritten release.
The list is now signed with an ed25519 key kept for this alone, and the
public half is allowed_signers at the repository root, so verification
does not go through the release page: ssh-keygen -Y verify against the
committed file, then sha256sum --check. Rehearsed on all three outcomes:
a good signature, a tampered pack caught by the sums, a rewritten list
caught by the signature.
The release steps sign and upload the signature, the README points a
downloader at the procedure, and the reproducibility section says what
each half proves. Rotation keeps retired lines so past releases stay
verifiable. Three tests hold the trust root, the signing step and the
documented principal in agreement.
The pages described workflows, an installer pinning and a CI permission
model that are not the ones in the tree. Corrected: the release process,
the CI table, the resolution chain and its statuses, the hash-mismatch
policy per verification mode, the archive convention, and the romset
recipe store.
The FAQ keeps the project's own reading of the legal question rather
than a version that reaches no conclusion.
Update wiki source files (the single source of truth for the site):
- tools.md: renumber pipeline steps 1-8, add step 6 (pack integrity),
add missing CLI flags for cross_reference.py and refresh_data_dirs.py
- architecture.md: update mermaid diagram with pack integrity step,
fix test file count (5 files, 249 tests)
- testing-guide.md: add test_pack_integrity section, add step 5 to
verification discipline checklist
9 new wiki pages: getting-started, faq, troubleshooting,
advanced-usage, verification-modes, adding-a-platform,
adding-a-scraper, testing-guide, release-process.
Updated architecture.md with mermaid diagrams, tools.md with
full pipeline and target/exporter sections, profiling.md with
missing fields, index.md with glossary and nav links.
Expanded CONTRIBUTING.md from stub to full contributor guide.
Filter .old.yml from load_emulator_profiles, generate_db alias
collection, and generate_readme counts. Fix BizHawk sha1 mode
in tools.md, fix RetroPie path, fix export_truth.py typos.
