First release with a real-mode receipt bound to an actual run of the published Phoenix pipeline.

What's new

  • Real-mode receipt at `examples/x-feed-real.receipt.json`, bound to `xai-org/x-algorithm@c3ef330`. Generated by cloning the upstream repo, downloading the 2.9 GB Phoenix LFS artifacts, running `uv run run_pipeline.py`, hashing all 8 model and config files, and signing the audit event.
  • Reproducibility demo (`npm run repro-demo`) showing wrapper-level determinism: two independent runs with the same input produce identical `input_commitment` and `output_root`.
  • Tamper detection demo (`npm run tamper-demo`) showing the verifier rejects any modification to a signed payload.
  • CI workflow (`.github/workflows/verify-receipt.yml`) verifying the receipt on push, PR, and daily schedule. Copyable into any recommender repo.
  • LIMITATIONS.md documenting the canonical caveats: execution binding vs ranking quality, mock vs real, output-bytes vs parsed-records, observer trust, regulatory framing.

Verify

```sh
git clone https://github.com/VeritasActa/x-algorithm-receipts
cd x-algorithm-receipts
npm install

Mock-mode receipt (instant, no artifact download):

npm run demo
npx @veritasacta/verify examples/x-feed-demo.receipt.json --jwks examples/demo.jwks

Real-mode receipt (already in the repo, bound to xai-org@c3ef3307):

npx @veritasacta/verify examples/x-feed-real.receipt.json --jwks examples/real.jwks

Inspect semantic fields:

node scripts/inspect-receipt.mjs examples/x-feed-demo.receipt.json
node scripts/inspect-receipt.mjs examples/x-feed-real.receipt.json

Tamper demo:

npm run tamper-demo

Reproducibility pair:

npm run repro-demo
```

RFC

#1 Add optional post-ranking audit event hook proposes a minimal in-tree hook for `xai-org/x-algorithm`. Filed on this repo because upstream Issues are disabled.

What this proves

Execution binding, not ranking quality. The receipt proves a specific output was bound to specific code, model artifacts, config, and input commitments at signing time. It does not prove the output is fair, truthful, or beneficial. See LIMITATIONS.md.
