- Replace all response.data ?? [] with (response.data ?? response)
pattern across 14 files to handle SDK array-shaped responses
- Normalize SDK parts in parts-reader.ts by injecting sessionID/
messageID before validation (P1: SDK parts lack these fields)
- Treat unknown part types as having content in
recover-empty-content-message-sdk.ts to prevent false placeholder
injection on image/file parts
- Replace local isRecord with shared import in parts-reader.ts
- Re-read messages from SDK after injectTextPartAsync to prevent stale
snapshot from causing duplicate placeholder injection (P2)
- Replace local isRecord with shared import from record-type-guard (P3)
- isTodo: allow optional id to match Todo interface, preventing
todos without ids from being silently dropped
- messageHasContentFromSDK: treat unknown part types as empty
(continue) instead of content (return true) for parity with
existing storage logic
- readMessagesFromSDK in recover-empty-content-message-sdk: wrap
SDK call in try/catch to prevent recovery from throwing
