Changelog

What shipped, dated. Each entry corresponds to a public, verifiable artifact — that's the house style.

  1. Incident record published — canned verdicts, 21-25 August 2026

    Four-day window in which /evaluate signed and returned receipts for evaluations it never performed. The signed layer halted every affected request; the presentation body did not disclose that. Fixes shipped 4a8b37177, 98b3b7e78, c28c5dd6f, 49261a37b, a8ce2a18d. External review by @giskard09 found and closed a same-class defect in the conformance sample and an unauthenticated signing path; kid separation remains open with no date. Full record: /incidents/2026-08-25-canned-verdicts ↗.

  2. Verifier v0.1.0 published to PyPI — three-outcome status semantics live on the released artifact

    pip install agentoracle-receipt-verify==0.1.0 · MIT · offline verification against the published JWKS. Public API exposes STATUS_VALID, STATUS_INVALID, STATUS_INDETERMINATE. Post-publish gate ran against the installed package in a fresh venv — the no-key path returns invalid rather than valid. pypi ↗

  3. Experiment A pre-registered — design frozen, three model families, results Sep 2

    Two deep-research agents, one gated through /evaluate (fail-closed, replans on failing verdict), 200 questions across four domains. Measured quantity: which citations survive independent verification. Ground-truth stack deterministic. The pre-registration document was public before any data was collected; the harness and the frozen question set land before the first run, on the schedule published in the repository README. pre-registration ↗

    Corrected 2026-08-17. This entry originally read “Pre-registration document, harness, and questions all public before any data was collected.” That overstated what was public: at the time of writing the harness was a disclosed stub and the question set was an empty array, both scheduled in the repository README for 2026-08-17, ahead of the 2026-08-19 run start. The pre-registration document itself was complete and public as described. No data had been collected at any point, and none has been collected as of this correction.

  4. Virtuals showcase merged — a live production receipt now sits in Virtual-Protocol/acp-cli-demos

    10 files, +670/-0, merge commit c08af80e7a12. Receipt blob d13a275e1c4d is byte-identical to the production receipt. Anyone can clone the showcase folder, install the verifier, and run python3 verify.py receipt.json against the live JWKS. showcase ↗

  5. Deterministic mode — POST /v1/verify-facts: six check types, no LLM in the trust chain, check_mode recorded inside the signed payload
