 - Prefer local-first search routing and remember Brave free-plan rate limits.
 - Keep backup/transcription infrastructure notes in long-term memory when they affect future operations.
 
+## Consolidation pass
+- Archived obvious low-value auto-generated session-summary files out of top-level `memory/` into `memory/archive/session-summaries/` instead of deleting them.
+- Archived files:
+  - `2026-03-02-2127.md`
+  - `2026-03-03-2223.md`
+  - `2026-03-03-session-greeting.md`
+  - `2026-03-04-0825.md`
+  - `2026-03-04-greeting.md`
+  - `2026-03-04-test-confirmation.md`
+  - `2026-03-05-heartbeat-ok.md`
+  - `2026-03-05-codex-error-type-error-error-t.md`
+- Rationale: these were mostly reset/greeting/test/heartbeat artifacts with little long-term value, but still worth retaining in case old session evidence is needed later.

 ## Follow-up intent
 - Be more disciplined about using the daily note as the default inbox and promoting only durable truths into `MEMORY.md`.
 - Avoid adding new one-off memory files unless the topic is truly long-lived.
+- Consider a later second-pass reclassification for remaining topical files (for example, move stable plans/references into clearer subfolders and fold tiny one-off notes back into day files where safe).
