109 Focused Tests Passed. The Final Video Still Wasn't Proven.Video
A green test suite did not prove that the final MP4 still matched the approved package. The repair binds the current video path and SHA-256 digest to the validation report.
The Identity Check This AI Video Pipeline Was MissingVideo
The publish gate now requires the reviewed package, story, current video path, and current bytes to agree, stopping stale state or the wrong artifact before release.
The Prompt Constraint That Kept This GPT-5.6 Sol Refactor BoundedVideo
One behavior, three integration boundaries, 12 application files, and no merge authority: the constraint that kept a real GPT-5.6 Sol refactor narrow enough to review.
I Gave GPT-5.6 Sol a Real Repo RefactorVideo
A bounded GPT-5.6 Sol refactor inside a real production video system, followed by an independent review that found the missing artifact-provenance guarantee.
Your Local AI Tools Should Train From Their LogsVideo
Local assistants already record failures, retries, repairs, and corrections. With training events, redaction, quality gates, and evals, those logs can become a disciplined learning loop.
