Full report and patch

Approved. The diff is limited to generation metadata and two transition documents. The previous and new public generated checkpoints have identical Git trees. The strict zero-line policy and SDK source are unchanged.

The inventory's 41 former mixed files match the pinned baseline's hashes and line counts, totaling 40,356 physical lines. The recorded modes match the 2,028-entry generated manifest. Historical measurements remain intact and are clearly separated from the current status. No blocking findings.

Source-only review: I did not run candidate tests, builds or generation. The compiler tests and legacy/native qualification remain author-reported. Hosted CI and the required human review remain separate gates.

Reviewed head: 398dfbd515fb0608c6ae26c1418b19f356006f8f; base: 3596d18f05b63081fd64c6da82b515293afb98c6.
