+# WP-201 live qualification evidence
+
+Task: DEV-000149  
+Observed: 2026-08-22 13:50 UTC  
+Target: production `docker.cin.su`
+
+The bounded `creator-advisory-synthetic-v1` corpus was executed inside the
+production cognitive network against the existing Lifeboat endpoint. The
+immutable artifact is
+`wp-201-live-qualification-2026-08-22-v1.json`.
+
+## Qualified evidence
+
+- provider: `local-lifeboat`
+- model: `domovoy-lifeboat`
+- binding revision: `594087847110549365`
+- result: `SUPPORTED`
+- quality: `1000/1000`
+- critical failures: `0/1000`
+- cases: 4/4 passed, including non-canonical action refusal and ambiguous destructive request clarification
+- observed case latency: 1135–2561 ms
+
+No binding was activated, promoted or reconfigured by this run.
+
+## Current fleet boundary
+
+The live readiness observation for the same production revision reports:
+
+- FAST: unavailable, `401 UNAUTHORIZED` from the configured CPU provider;
+- MEDIUM: `NOT_CONFIGURED`;
+- HEAVY: unavailable, GPU endpoint timeout;
+- LIFEBOAT: available and selected as fallback.
+
+Therefore this evidence qualifies the Lifeboat synthetic behavior only. It does
+not claim that FAST, MEDIUM or HEAVY is qualified, and it does not establish
+throughput/concurrency, long-context, license, resource-saturation or restart
+qualification. Those remain explicit follow-up evidence requirements.
