Mission 6b reconciliation: status#9564 integrates #9531’s Voice work with Mission 6’s resumable browser mutations. It preserves #9531’s core contract: completed transcript → shared Combined testing found and fixed several integration bugs: browser work running after local Stop, textless tool failures appearing ready, lost client-tool Voice origins after history folding, unstable delivery payload ordering, missing stopped metadata, and cleanup/conversation-switch/late-speech races. Current automated evidence: 39/39 uncached tasks and 1,318 tests in 167 files. This is stronger integration coverage, not Mission 6b acceptance. Remaining acceptance gaps

🌟 What is the purpose of this PR?
This PR builds on #9528's unified Flue conversation route and restores the Voice safety and UX behavior needed on top of it.
A completed spoken transcript follows the same path as typed input:
Voice → shared panel useChat → browser Flue transport → /agents/chat/:instanceIdThe response shown in the panel is the canonical Brunch text passed unchanged to TTS. Initial speech may start from a durably completed, submission-correlated canonical segment while the rest of the Flue submission continues; settlement still gates replay and the next input turn.
This PR does not restore Brunch
/api/chat, add a direct VoiceFlueClient.send()path, rewrite responses with a simplifier, mountbrunch_ask, or add Petri-net generation.🔗 Related links

The existing before/after values came from one author-observed real microphone-to-audible turn per side. Raw samples and a reproducible artifact bundle were not retained, so these numbers are diagnostic only and are not acceptance evidence. The required 10+10 controlled comparison remains open.
