Fix bulk notification dismissal at palace scale - #28
Conversation
📝 WalkthroughWalkthroughThe dashboard now combines physically chunked Chroma records into logical drawers across listing, search, and drawer reads. The client sends seen-state updates in batches, and the palace schema version is updated to ChangesLogical drawers and seen-state persistence
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to Bulk dismissal can still lose unsent batches while appearing complete, causing notifications to reappear, and large searches can fail with empty results. These concrete correctness issues make the PR unsafe to merge until both failure paths are addressed. Sequence Diagram(s)sequenceDiagram

Avoid SQLite expression-depth limits for broad chunked searches.
When _search_drawer_ids returns up to 2,000 IDs from distinct chunk parents, this predicate creates over 1,000 OR terms. SQLite can reject the query with Expression tree is too large, and the handler then returns an empty search result. Batch the parent expansion or use a temporary target table. Add a regression test with more than 1,000 distinct chunk parents.

Retry failed batches before treating the dismissal as persisted.
When one request fails, this catch exits the loop. The failed batch and every later batch are discarded. The callers already mark all IDs as seen locally, while include_seen: false prevents response reconciliation. The server can therefore persist only part of a bulk dismissal, and dismissed notifications can reappear after the next poll or refresh.
Keep failed batches in a retry queue with bounded backoff, or await the persistence result and surface an incomplete dismissal. Do not silently drop unsent IDs.

What changed
Why
With the Exalta import, Mark all sent thousands of IDs in one request. That exceeded Apricity’s 20 KB request limit, returned HTTP 400, and caused notifications to reappear after refresh.
Impact
Single dismissals are unchanged. Bulk dismissals now persist without relaxing the request-size safety limit.
