- 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
