{"content":"IDChat Native migration Task 9.\n\nCommit 5593adf feat: add native chat store.\n\nAdded the native chat Zustand vanilla store with account/runtime/socket state, channel merge, and message merge behavior. Message ordering now matches the storage repository semantics: timestamp, numeric index, then deterministic dedupe-key tie-breaker, with tests for channel replacement, txId message replacement, and same-timestamp ordering.\n\nVerification: yarn test:chat-native src/chat-native/state/__tests__/useNativeChatStore.test.ts PASS, 9 suites / 51 tests. Spec and quality subagent reviews approved. Backend APIs and Socket.IO remain unchanged.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
