Addresses the 2nd PR #138 review (test debt + the Variant-B architecture ask). The new→persisted chat id lifecycle (mount key, both adoption paths, the history-load latch, the render-phase reconciler, onTurnFinished) is moved out of the 768-line window into a new useChatSession hook driven by a pure threadSessionReducer (reconcile/adopt), so adopt-vs-switch is one explicit dispatch point and the scattering the review flagged is gone (window: 768→~620). Tests (the blockers): - use-chat-session.test.tsx — hook-level locks incl. the #137 regression (adopts the authoritative streamed id 'A', NOT chats.items[0]='B' — fails on the old heuristic), the error-path fallback (arm/adopt/ambiguous/add+delete), the disarm-on-reconcile lock (a fallback armed then switched away must not be adopted by a late refetch), in-place-adopt-keeps-key vs external-switch-remount, and the waitingForHistory latch. - extractServerChatId (reading message.metadata.chatId) and newlyAddedChatIds extracted as pure helpers with unit tests; threadSessionReducer tested. Cleanups: single canonical #137 explanation in adopt-chat-id.ts (other sites reference it); fallback effect computes the set diff once; invalidate callbacks memoized; redundant invariant tests folded. Behavior preserved — re-verified live (z.ai glm-5.2): new-chat adopt + 2nd turn in the same row, no mid-conversation remount, two-tab race leak-free, switch to an existing chat reseeds full history, reload restores history.
