Addresses the PR #138 review. Blocker 1 — duplicate chat row: a brand-new chat whose first turn errors BEFORE the SSE 'start' chunk never receives the authoritative chatId, so metadata adoption can't run; a retry then sent chatId:null and the server inserted a SECOND chat row, orphaning the first turn. Keep metadata adoption as the primary path (resolveAdoptedChatId) and add a bounded, unambiguous fallback: on a new-chat finish with no server id, snapshot the known chat ids and, once the list refetch lands, adopt the SINGLE newly-appeared id (pickNewlyCreatedChatId). Zero or >1 new ids (e.g. two tabs racing) → no adoption — no items[0] guessing, so #137 stays fixed. The wait-for-refetch guard compares set membership (robust to a concurrent delete), and the diff dedupes so a repeated id from a paginated list never reads as ambiguous. Blocker 2 — tests: new adopt-chat-id.test.ts covers both pure helpers (adopt decision + newly-created-id diff incl. dedupe/reorder); the server messageMetadata callback is extracted to chatStreamStartMetadata and unit-tested (start -> {chatId}, otherwise undefined).
