 - Tighten inverted smoke canaries: assert the expected `[FAIL]` marker text (`skipped on ... should run` / `missing post-exit sidecar`) alongside wrapper exit 1, so a canary that dies for the wrong reason does not satisfy the gate
 - Overlapping / mirrored UV islands as a *shipped* pathology (not lightmap `--falsify`): SAT hits matching a constructed overlap, then glTF TEXCOORD survival. Deferred — `lightmap-uv-channel` already owns the zero-overlap gate.
 - Vendor CC0 asset fixtures (Kenney, Quaternius, ambientCG only — no aggregators) as `.glb` not `.blend`, with per-fixture provenance records mirroring the Free-Game-Dev-Assets frontmatter schema. Permitted only where the assertion is an invariant over the fixture rather than a measurement of it. Deferred pending a decision on repo weight and CI fetch policy.
-- Falsification flags on shipped examples (Phases 6–8 `--skip-delete` / `--unpair-*` / `--bypass`, Phase 9 `--silent-handler` / `--wrong-text`, Phase 10 `--no-dissolve` / `--identity` / `--no-duplicate`) were proven local-Windows only — chat and `.scratch`, not CI history. Decide later whether a cron should exercise them or whether flags in the scripts are sufficient record.
