 - **Audio-reactive waveform is flat on the Observation surface**, as explicitly scoped out of 6.7B. No audio graph exists there; `observation-engine.js`'s pre-existing `am.analyser`-null guards degrade it gracefully. Deferred, not solved, per the governing report.
-- **`postmessage-interop.test.js`'s 5 failures** (see §J) are a pre-existing `5.2`/`5.3` handshake-gating mismatch between this SciFi-XZBT change and an independent, prior `src/host.js` change, outside this step's edit scope. Needs separate resolution — likely a version-gating fix in `contract-adapter.js`'s `_setupWindowBridge`, but that edit was withheld here because the report marks it must-not-change for 6.7B.
-- **Live browser verification and the packaged single-file build were not exercised** in this session (§K) — recommended before treating 6.7B as fully accepted.
