Release-integrity lane before the tag.

Public history audited — 454 blobs across all 29 reachable commits, by content not path. No restricted provider content has ever been committed publicly.

One machine-readable authority replaces scattered assumptions. check-licensing extended (not duplicated) to read every text surface with claim context, restricted document formats, symlinks leaving the repository, MPL application, and the built artifacts and SBOMs rather than the templates.

Two defects it found: the .deb declared no licence anywhere machine-readable (DEP-5 copyright added), and a private filesystem path had been written into public files.

16 legitimate lines produce zero false positives. 84 injections, all executed and detected.

A release-integrity lane before the tag.

PUBLIC HISTORY AUDIT. 454 blobs across all 29 reachable public commits, inspected
by CONTENT and not only by path. Zero PDF, XLSX, DOCX, CSV or archive has ever
existed publicly. Every framework marker found is a clean-room prohibition, the
README's NOT YET CLAIMED list, or an injection's own synthetic string.

ONE MACHINE-READABLE AUTHORITY. public_licensing_policy.json replaces licensing
assumptions scattered across scripts. check-licensing was EXTENDED, not duplicated,
and now reads every text surface with claim CONTEXT (a provider token alone is not
a finding — "do not copy from CIS" names a provider in order to forbid it),
restricted document formats, symlinks leaving the repository, MPL application, and
THE BUILT ARTIFACTS and SBOMs rather than the templates that produced them.

TWO DEFECTS FOUND BY IT. The .deb declared no licence anywhere machine-readable:
the RPM carried License: MPL-2.0 while Debian's mechanism, a DEP-5 file at
/usr/share/doc/<pkg>/copyright, was simply absent. A licence the packaging format
cannot express is one a package manager cannot report. And the privacy gate caught
a private filesystem path written into public files — a public file does not get to
describe a private filesystem.

FALSE-POSITIVE QUALITY. 16 legitimate lines produce zero findings; 6 real claims
are all caught. Noise is a defect.

HARNESS BLIND SPOT. _tree_digest used find -type f, which excludes symlinks
entirely — a blind spot precisely where it matters, since a symlink is one of the
ways restricted content reaches an artifact without being committed to it.

REPORTING CORRECTED. Executed detections are no longer added to declared skips, and
the DEB reproducibility claim is narrowed to what was demonstrated.

Gates 18. Injections 84, all executed and detected.

Implements: D-84, D-90, D-111, GOV-001, GOV-002
