+# Local memory bugfix notes (2026-04-17 v2)
+
+This package includes the following fixes:
+
+1. Remote memU failures no longer delete queued messages before successful persistence.
+2. Remote memU success path no longer removes queued messages twice.
+3. Remote provider selection now requires full memU configuration, not only an API key.
+4. When remote memorization cannot start, the service falls back to local controlled memory.
+5. `doNotRememberThis()` now reuses an existing suppression rule instead of creating duplicates.
+6. Conflict notes are deduplicated, and conflict state is recalculated so stale conflict metadata is cleared.
+7. The Node engine requirement was relaxed from `>=23.11.1` to `>=22.0.0` to avoid blocking install in common environments.

+# Local memory patch notes
+
+This package is based on `memUBot-main-local-memory-explainability` and includes a focused follow-up patch to make the local memory path more usable.
+
+## What was patched
+
+- Switched memorization to **auto-select local provider** when no remote memU API key is configured.
+- Fixed the **duplicate local write / queue retention bug** by clearing queued messages after successful local memorization.
+- Added a **local fallback** for `memu_memory` retrieval, so memory retrieval can work without cloud memU.
+- Added **delete by source platform** through service, IPC, preload, and renderer hook.
+- Expanded local list/search filters with:
+  - `created_after`, `created_before`
+  - `updated_after`, `updated_before`
+  - `min_confidence`, `min_importance`
+- Added basic retention enforcement in local listing by excluding expired memories.
+- Added lightweight duplicate avoidance in local memorization.
+
+## Still not fully finished
+
+- Conflict detection is still not fully implemented.
+- Time decay is not yet applied as a scoring factor.
+- Sensitivity-specific retrieval policy is still basic.
+- The local retrieval scoring is heuristic, not embedding-based.
+- I did not run a full project build inside this environment, so treat this as a strong code patch rather than a fully validated release build.
