The feedback hook derives injectedIds by regex-parsing event.prependContext, but auto-recall injection formats lines as category/scope prefixes (e.g. [category:scope]) and does not include memory IDs, so this match path returns no IDs in normal runs. Because injectedIds stays empty, the scoring loop never executes and bad_recall_count/importance are never updated, effectively disabling the new recall-governance feature despite pendingRecall already storing the selected IDs at injection time.
Useful? React with 👍 / 👎.

Once a pendingRecall entry exists, this agent_end handler keeps overwriting its responseText on every subsequent turn, even when no new recall was injected, and the map is only cleared on session_end. Without deleting the entry after a scoring pass, later turns can repeatedly reward/penalize the same old recallIds based on unrelated responses, which will skew importance over long sessions.

… (Codex review)
P1: before_prompt_build was trying to parse memory IDs from
prependContext via regex /\[[a-f0-9]{8,}\]/gi, but auto-recall
injects memories with [category:scope] prefixes (e.g. [reflection:correction])
and does NOT include memory IDs. pending.recallIds already contains the
correct IDs — use them directly instead of parsing a text format that
never contains IDs. This unblocks the scoring loop so bad_recall_count
and importance are actually updated.
P2: pendingRecall entry was never deleted after scoring, causing
subsequent turns to re-score the same recallIds against a new
responseText, distorting importance over time. Delete the entry
immediately after the scoring loop completes.
Fixes two Codex review comments on PR CortexReach#736.

Compare
- Remove broken prependContext regex parse that always returned empty
(prependContext format is `[category:scope]`, not hex IDs).
Scoring now uses pending.recallIds directly (populated by auto-recall hook).
- Add pendingRecall TTL eviction (10min max-age) to prevent unbounded Map
growth when session_end never fires (crash, SIGKILL, etc.).
- Add pendingRecall.delete(sessionKey) after scoring loop to prevent
re-scoring same recallIds on subsequent turns (Codex P2).
Fixes: C1 (CRITICAL - scoring dead code), C3 (CRITICAL - re-scoring),
TTL gap (CRITICAL - process crash leaks).

Review action: COMMENT
Thanks for the PR. GitHub currently reports this branch as not mergeable (mergeable=CONFLICTING, merge_state_status=DIRTY), so I am deferring deep review until the diff can be reviewed against the current base.
Please rebase onto the latest base branch, resolve the merge conflicts, and push the updated branch. Once it is cleanly mergeable again, I will re-run the full review on the updated diff.

Summary
Phase 1 of Proposal A: implements a feedback-driven recall governance loop that detects when auto-recalled memories are actually used vs not referenced in the agent response, and applies configurable scoring penalties accordingly.
See RFC: #569
What this PR does
Core feature: isRecallUsed() feedback loop
When auto-recall injects memories into context, the system tracks which recalled items the agent references in its response. If a recalled memory is not mentioned, it incurs a scoring penalty — reducing its chance of being recalled again.
Key components:
isRecallUsed(): keyword-based usage heuristic — checks if response text contains natural usage markers (e.g. "記得", "記住了", "之前說的", "根據...") that indicate the agent is referencing the recalled memorystore.update({ importance })+store.patchMetadata({ bad_recall_count })feedbackActivationThreshold(how many recalls before feedback activates),suppressionThreshold(>= 3 consecutive unused before penalty)Bugs fixed during review
before_prompt_buildregex parse was dead code —prependContextformat is[category:scope], not hex IDs, so regex/\[([a-f0-9]{8,})\]/gialways returned[]. Scoring loop never ran. Fix: usepending.recallIdsdirectly (populated by auto-recall hook).pendingRecall.delete(sessionKey)was only called insession_endhook. Without it, the samerecallIdswould be re-scored on every subsequent turn indefinitely. Fix: addpendingRecall.delete(sessionKey)after scoring loop completes.pendingRecallMap had no TTL eviction. Ifsession_endnever fires (crash, SIGKILL, unhandled exception), entries accumulate forever. Fix: add 10-min max-age eviction when reading stale entries.Previous (pre-review) claims that were incorrect
