 # Area: Client reliability (client-reliability)
 
-## Current assignment: client-reliability-5 — active probe investigation
+## Current assignment: client-reliability-5 — prevent orphaned mirror continuation
+
+Investigation at0c1dd7e8 found a narrow defect, independently reproduced by dispatch at47953970 (administrative roster only): after last-owner disposal during active primary media, primary error starts1 fresh mirror HEAD(expected0). /tmp/bitvid-dispatch-5-active-url.mjs mirror-disposed --expect-no-obsolete-head exits1 after cleanup/retry; mirror-shared control exits0/healthy,resources0/slots0. Bounded active retention/success caching itself is intentional and not a defect.
+
+Implement controller-only lifecycle guard before next mirror request: temporary ownership js/ui/urlHealthController.js, focused tests/url-health-lifecycle.test.mjs and your unique integrity/evidence notes. Existing ownership hook is sufficient. Do not change observer/app/shared cache/HEAD-media-HLS-torrent abort,TTLs/limits/mirror order. Ensure cancellation settles with explicit cancelled outcome, no negative cache, no stale UI or newer inflight deletion. Preserve shared/rejoining live owners and ordered mirrors, active healthy cache and normal timeout/retry behavior. No competing writers: storage-cors owns only storage helper; playback-qa product read-only.
+
+Read current rules/test integrity before edits; retain actual observer/controller/cache regression with controlled external IO and mock clock, no sleeps/retries. Test disposed active failure starts0 mirror HEAD; shared/rejoin owner continues; active success cache,timeout/retry and inflight identity preserved. Every new scenario needs reverted failing mutant. Relevant focused tests/lint/build; coordinate full suite/normal queue through dispatch before expensive run (roster full gate currently underway). QA initially owns shared browser: do not launch browser until dispatch allocates it; request availability and use only your own server/port. No blanket prior-suite reruns for administrative edits. Commit item5, merge unstable (never rebase), unchanged gate/durable ancestry before close. CLI/agent/lander launch must unset inherited NODE_TEST_CONTEXT test transport (operational environment correction, no assertion/gate change). Send blocker/product landing/final events with exact checks/counts/gaps. Dispatch owns preview3000 refresh. No subagents/kit/scheduler/external operations. Continue next actions via dispatch routing under existing owner direction.

Read RULE-CHANGES, KNOWN_ISSUES, PROGRAM, and performance-efficiency-plan Stage3. Items3/4 are completed: queued torrent/URL cancellation shipped; do not repeat their full qualification.

Keep item5 client-reliability; add storage-cors-1 offline existing-origin preservation reproduction and playback-qa-1 independent local fallback qualification. Preflight public open PR count0. Inspection confirms helper constructs requested-origin-only PutBucketCors; QA gap documented in Stage3 and prior item4 report. Neither task assumes a new product defect.
 - Three worker target, disjoint branches/worktrees/files. QA browser first; focused offline work overlaps; full suites/product gates coordinated one at a time. Measure pickup latency, real outputs, gate/browser/tool stalls and durable queue outcomes. No credentialed cloud/live peers/production activity. Launch pending roster landing.

+- Item5 narrow fix routed after worker+dispatch reproduction: prevent fresh mirror HEAD after disposed last-owner active-media error; controller+focused URL lifecycle tests only. Preserve bounded active/cache/shared/rejoin/timeout semantics, no active abort. Parallel trial CLI/agent/lander launches clear inherited NODE_TEST_CONTEXT transport; exact gate/assertions unchanged. Original roster gate hit binary capture cap, not identified product assertion. No kit patch.

 - Owner authorizes bounded parallel trial via interpreter: dispatch plus existing client-reliability and two new areas storage-cors/playback-qa. Separate worktrees/disjoint write ownership; no competing app/grid/URL writers. QA initially owns browser; one expensive full gate at a time coordinated through dispatch. Each worker sends read/next-action and timed contention/evidence events. No new external authority or scheduler changes.
