aim-purge

Purge old memories from Qdrant collections with safety guards. Default (no `--confirm`): dry-run preview — shows what would be purged, no deletions. `--confirm`: executes the purge. **Irreversible** — audit log written to `.audit/logs/purge-log.jsonl`. ## Canonical Execution ```bash "${AI_MEMORY_INSTALL_DIR:-$HOME/.ai-memory}/scripts/memory/run-with-env.sh" purge_collections.py \ --older-than <duration> \ [--collection <name>] \ [--confirm] ``` ## Parameters - `--older-than` (required): duration string — `30d`, `2w`, `3m`, `1y` - `--collection`: limit purge to one collection (default: all four) - `--confirm`: execute the purge (absence = dry-run safety gate) ## Script `scripts/memory/purge_collections.py`
