/cs-forgetting-audit

The short pass. Skip the cost and architecture work; answer one question about `$ARGUMENTS`:

> **What leaves this store, and on what rule?**

Run

If given a policy JSON:

python ${CLAUDE_PLUGIN_ROOT}/skills/memory-engineering/scripts/forgetting_policy_linter.py --policy <policy.json>

If given a directory, first show what is actually accumulating, then gate:

python ${CLAUDE_PLUGIN_ROOT}/skills/memory-engineering/scripts/memory_density_auditor.py --dir <path>
python ${CLAUDE_PLUGIN_ROOT}/skills/memory-engineering/scripts/forgetting_policy_linter.py --policy <policy.json>

If no policy file exists, that is the answer — nothing leaves the store. Show what `--sample-failing` blocks, then help write one from `skills/memory-engineering/assets/forgetting_policy_template.md`.

The two blocking checks

• **F1 — an explicit forgetting rule** (TTL, capacity bound with a stated

eviction order, or relevance decay). None of the memory systems in the Stanford evaluation prunes or forgets by default: if it was not built, it does not exist.

• **F4 — contradictions surfaced, never auto-merged.** `newest_wins`,

`auto_merge`, `overwrite` and `last_write_wins` all fail. Two memories that disagree may both have been true in different contexts, and silently resolving them destroys the only evidence the conflict existed.

The other six checks (dedup, consolidation, scope, audit trail, rollback, growth-slope monitoring) degrade the verdict to CONDITIONAL rather than failing it.

Report

1. **Verdict** — PASS (0) / CONDITIONAL (2) / **FAIL (4)** 2. **Every failing check** with its ID, why it matters, and its fix 3. **The one thing to fix first** — F1 or F4 if either failed; otherwise the highest-leverage warning

Do not

• Do not soften a FAIL into a suggestion. Retrofitting forgetting onto a full

store is a data migration with a judgment call attached to every record — which is exactly why it never happens.

• Do not accept "we will add pruning later." Later is the failure mode.
• Do not propose auto-resolution for contradictions, in any form.
