Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review. 📝 WalkthroughWalkthroughThe RAG store now splits chunk sets across file parts, persists part and revision metadata, and uses revision-guarded refresh and removal operations. It scans and retries cleanup for obsolete parts. Tests and documentation cover these flows. ChangesMulti-part RAG storage

- Around line 550-557: Extend the existing refresh try/catch to include the
upsertRagDocument call, ensuring metadata persistence failures trigger cleanup
of every new path in filePaths via deleteFileChunks while preserving the current
cleanup logging and behavior for chunk and embedding write failures.
- Around line 494-495: Update the cleanup loop around previousFilePaths and
deleteFileChunks so every prior file path is attempted even when one deletion
fails. Use Promise.allSettled() or equivalent per-path failure collection, then
report the cleanup error after all deletion attempts complete while preserving
the existing replacement metadata behavior.

The last two Sonar complexity annotations are addressed in b699dfe by separating bounded part inspection and metadata-write recovery into focused helpers. Existing behavior is preserved: all 162 embedding/lifecycle steps, typechecking, formatting and lint pass, and the complete-branch review is clean. CI is running on this final SDK head. API dependency #4862 now has all review and Sonar fixes committed locally with 20,930 unit and 2,595 integration tests passing; its final branch review precedes publication and staging deployment. The deployment dependency thread remains open until that deployed proof is available. |

Final checks passed for bb49bb5: all review threads resolved, current-head Codex review clean, CI workflow successful, Sonar zero new issues with 82.4% changed-code coverage. The current SDK passed 22 staging checks against deployed API b996e0fa, including the injected unreadable-orphan case with real deletion; both rounds of disposable fixtures were deleted and independently verified absent. Merge confidence: 95%. Added to the normal merge queue and monitoring its checks. |



Importing a Cloud RAG document with 501 chunks failed because each chunk POST replaces the complete chunk set for one file. Store batches in separate file parts under the same document ID, preserving all content and embeddings.
Refresh and removal use document revisions so a delayed metadata write cannot overwrite a newer refresh or recreate a deleted record. Cleanup discovers orphaned parts through the document-specific file namespace, requests only paths, and inspects live chunks with bounded concurrency. Partial discovery failures preserve successfully found paths for cleanup; known parts are attempted before errors are reported. Empty historical file nodes stay out of the cleanup journal.
The required API revision support is delivered in veryfront/veryfront-api#4862, staging merge
