+- Candidate3474668a832f0dc4d58edb93afbc8786f9509114 inspected via git show: product only controller18added/2removed; cancellation hook and synchronous marker; test contract correction plus strict replacement/shared/legacy/FIFO/live-timeout controls. Integrity note and14mutant exact failures inspected; worker-derived37focused/14mutants/lint11, not independently rerun in full.
+- Independent command `env -u NODE_TEST_CONTEXT node /home/user/Documents/GitHub/bitvid-client-reliability/tests/url-health-lifecycle.test.mjs`: natural exit0,29pass/0fail/0cancel/0skip,313.217572ms. Output /tmp/bitvid-dispatch-client8-candidate-lifecycle.log.
+- Read-only candidate hash verification: controller e2f66a9f9fb6bc10ef71c704412d2cf4d618a360 and lifecycle bac5b283fed76b965ce3528f48070a86f06fc0f3 exactly match committed3474668a. No edits in worker tree; executed only focused test.
+- Exclusive full/normal landing slot granted20:56:47UTC. Queue0 at grant, other2workersidle; worker instructed single unchanged normal gate authoritative full, no duplicate full. Build/browser not granted pending product landing; dispatch holds docs submission to avoid competing gate.
+- Unverified: full gate/landing,actual native media/resource/network release,CPU/RSS,live playback/peers,HEAD/HLS/torrent cancellation. No allStage3 claim.
+
+- START received20:57:13UTC;MCP land_status independently reports3474668a gating,host drain alive383053 since20:57:26UTC. Earlier sandboxCLI not-running/queued is not host-liveness proof. No duplicate drain or gate started. Durable outcome pending.
+
+- Worker recovery clarification20:57:40UTC:initial sandbox auto-drain exited before running;worker used approved env-cleared fleet lander start for same submission,without resubmission or gate change. Initial queued/notrunning was real according to worker,not established solely as sandbox liveness limitation. Subsequent independent MCP stillgating/alive383053;no full result yet.

Independent selection audit from runner discovery rules:expected432,starts432,unique432,missing0,extra0. Worker context/shard clearing is reported;retained output is not full install/process transcript and no absent stdout finalmarker inferred.
+- Approved `git merge --no-edit unstable` fast-forwarded dispatch to43cb1baf,exit0 (sandbox Git metadata read-only needs approved host operation).
