 **Keys are permanent and use bare agent name aliases.**
 
-- **Duration**: `null` — keys never expire. NOT enforced today: CT 116 `litellm_config.yaml` has no `default_key_generate_params` block, and a key generated with no explicit models comes back with an empty models list. OPEN policy question: should agent keys expire by default? (captain security-policy decision, raised separately.)
+- **Duration**: `null` — keys never expire by default. **Expiry must be set EXPLICITLY at creation** with the `duration` parameter (e.g., `90d` for 90 days). The 90-day default is the standard; however, the config default is **NOT honoured** by LiteLLM 1.99.1 (verified on CT 116: a key generated with no explicit duration returns `expires=null`). This has been recorded in `/opt/inference-harness/litellm_config.yaml` to prevent re-filing as a bug.
+- **Daily Audit**: A daily audit job runs at 00:00 UTC (`/usr/local/bin/litellm-key-renewal-ct116.sh`, cron 00:00). It is **AUDIT-ONLY** and does not perform renewal. It lists every key, reports those with no expiry and those inside a 14-day warning window, explicitly EXCLUDES `abiba-pi` and `koby` (report-only, and .129 must never be touched), and logs `RENEWAL-REQUIRED-BUT-NOT-PERFORMED + NO KEY WAS CHANGED` when renewal is skipped. **Renewal is NOT implemented** — keys must not be rotated until delivery (vault injection + consumer verification) exists and is proven end-to-end.
+- **Exclusions**: `abiba-pi` and every firstmate/secondmate/crewmate key stay **WITHOUT an expiry** until a proven renewal path exists. `koby` is **report-only** (never touched). These exclusions are enforced by the audit job.
 - **Alias convention**: bare agent name only (e.g., `tanko`, `mumuni`, `koby`, `koonimo`). No dates, no versions. The alias IS the identity.
-- **Rotation triggers**: compromise, personnel departure, or quarterly security hygiene. NOT calendar-driven.
+- **Rotation triggers**: compromise, personnel departure, or quarterly security hygiene. NOT calendar-driven. Manual rotation is permitted only when the renewal delivery path is proven and verified on a throwaway consumer before production use.
 - **Max budget**: $100 per key (config default).
