Controller/observer/cache diff between filedAt and HEAD is empty. Item still applies; claimed. +- Scratch: /tmp/client9-head-repro.mjs, derived from real lifecycle fixture; imports actual observer/controller/cache. Controlled fetch and AbortSignal; manually driven positive-delay timeout callbacks; actual DOM/media events. Zero-delay JSDOM tasks use native timers.

Last owner leaves HEAD1/abort0/timer1(5000ms)/unsettled/cache0/media0/video slots0/queued0/original inflight retained. Rejoin starts1 HEAD total, expected2. This is retained network work, not media-slot retention: HEAD has no shared slot cap in this controller. +- Eight natural passes (exit0, 1 scenario each, cancelled0): shared, cross, legacy, live-success, live-error, live-timeout, late-success, late-error. Shared survivor remains un-aborted and receives healthy result; disposed badge checking. Live HEAD success/error/timeout proceed to successful controlled media and healthy cache; timeout abort1. Completed probe timers0, video slots0. Late HEAD success/error after disposal settles null/cache0/media0/mirror0; existing guards work eventually, but not promptly. +- Cleanup resolves all controlled outstanding HEAD requests, completes created media, disposes registrations, restores globals and closes JSDOM before natural exit. Initial diagnostic intercepted a JSDOM0ms timer; corrected capture to delegate0ms tasks, repeated all11 modes above. Final pass timer counts exclude no real probe timer. +- Inspection: retainUrlProbe calls lifecycle.cancelActive on final owner loss, but probeUrl HEAD phase installs none. Existing hook only covers active media. Proposed smallest product boundary: js/ui/urlHealthController.js probeUrl HEAD phase only; register identity-checked lifecycle cancellation hook, mark cancelled synchronously, abort/race-settle cancelled, clear timer and hook on every completion; explicitly skip fallback/mirrors/cache on cancel. Existing shared-owner release logic/cache identity guards stay unchanged. +- Proposed retained test boundary: new focused HEAD lifecycle suite or tests/url-health-lifecycle.test.mjs plus unique integrity/spec notes. Preserve current29 media scenarios and live HEAD error/timeout fallback. Add both rejoin timings, shared/cross/legacy controls, cancellation with abort-unresponsive transport, late callbacks/replacement identity and transition-to-media/FIFO checks before readiness.
