Play & join starts or joins a shared listening clock and real RelaySwarm participation. For a new room, the first full-recording viewer prepares a bounded verified media reservoir locally before publishing the shared start time; preparation does not count as an active listener. A viewer still preparing a private start adopts a verified active room promptly, retires its empty old loader before the acknowledgement and preserves the original Play request; a failed acknowledgement restores an explicit retry. Cancelled or replaced asynchronous setup failures cannot fail a newer Play request; genuine current publication failures still restore retry. Existing rooms keep their advancing clocks and later listeners join live, the starter can leave while others continue, and the room expires after the last listener leaves a short grace period. Pause leaves; Play rejoins live. The recording loops while occupied; the 1080p excerpt has its own room. The live listener ticker includes joined listeners and excludes read-only page observers; Play/Pause events update it directly, with lease expiry for abrupt departures and unknown status during lost room observation. A confirmed empty room invites the first listener to start. One visible player per visitor, room participants distinct from locally connected peers, stable identity mapping through peerConnectionDetails(), proportional media-batch movement and rates, source-host feeds, explicitly self-reported remote links, separate loaded-source/verified-peer/upload counters and recent local peer contribution. Loaded source includes browser cache; playback details distinguish completed source response bodies from network and cache when timing coverage is available. Cache hits do not animate as fresh local network traffic; concealed timings remain unavailable. The browser integration pins RelaySwarm source e910147 (package version 0.4.4), including bounded rolling startup planning from verified future-load timing, with sustainable peer waits, range-sized WASM upload inputs and cached schema-3 mixed admission despite late whole-object estimates. Confirmed recorded main media requires a live same-key fetch lease before waiting for unavailable video; live and unknown playlists retain bounded seeding coordination. Sharing continues throughout active playback without an elapsed-time or cumulative-byte cutoff; upload rate, peers and cache remain bounded. Known pinned recordings use a client-generated bounded sliding live playlist with discontinuities across programme wraps and one visible player. The 267.32-second 4K programme preserves every original audio packet; a separately named, hash-pinned final fragment removes only 32 video frames after the soundtrack ends. The init and first 133 fragments remain byte-identical; the old immutable assets remain available. The next head can load before the tail ends; normal wraps do not end the element, reset its raw time or trigger replay priming. The bounded playlist retains 24 seconds of metadata behind the room clock so a slow initial response does not immediately eject the playhead; this does not enlarge the four-second media back buffer or encoded-media cache. A fixed per-session timeline origin maps raw media time to the shared clock; programme phase drives displayed time, telemetry and the musical pulse. Metadata preparation and peer creation remain after Play. Canonical manifest hashes and exact media URLs are checked, virtual global sequence/discontinuity values are signed against the unchanged piece catalogue, and a separate source/quality/epoch/manifest/duration cohort isolates this mode. Unsupported metadata and native HLS keep the ordinary VOD fallback; automatic clock corrections wait for sustained drift and stable, safely buffered playback, with the measured seek interruption added to the drift threshold, without changing music tempo. The responsive swarm picture keeps short labels and puts transfer rates and contribution statistics below it. A 16 KB score derived from the soundtrack drives a musical broadcast pulse against actual media time; pause, buffering, hidden pages and reduced motion stop it. This does not establish exact global audience counts or multi-speaker audio synchronisation. iPhone and iPad use the same peer-capable HLS path as other MediaSource-capable browsers; browser identity does not bypass sharing. The public Spry credential endpoint remains unconfigured pending an independently operated public endpoint. When configured, active playback requests and renews unique temporary TLS credentials from that independently operated instance, alongside STUN discovery. The supported public service uses its four-field credential contract and fresh one-hour leases, separately from KithMoot paired/private access. The final public instance endpoint remains operator configuration. This supplies a route for browsers that restrict direct UDP, including default Vanadium configurations. The bundle contains no relay password or operator root secret; availability diagnostics contain no credential. Pause cancels renewal. Issuer or route failure preserves HTTPS playback. Playback details can save or share a local JSON report with at most 240 one-second observations of actual frames, buffering, stalls and verified peer traffic, omitting network addresses, keys and credentials; no report is uploaded automatically. The HLS module prepares before Play without media requests or a player. The first tap attaches the selected media source and requests audible playback before awaiting room or peer setup; initial playback no longer waits for paused priming. This preserves request ordering but does not establish physical iPhone acceptance or stall-free startup. VOD fallback replay can still use a safely buffered current position while retaining buffered correction to the room. Reports retain raw media position/buffers and expose recording phase/duration separately; infinite continuous-media duration stays unavailable rather than being relabelled as the finite recording duration. Healthy network-stalled events with future data do not count as playback waits. The deployed 26 October 330-second same-M4 run used two fresh HTTP-cache-disabled Chrome profiles and the actual CDN assets, with no asset, controller or RTC overrides. Both had zero observed post-frame stalls/drops through the programme wrap and at least 60 seconds afterwards; accepted peer shares were 21.05% and 45.31%. First frames took 12.979 and 5.030 seconds. One midway report export per viewer remained in all measurements; A retained one nonfatal pre-frame aborted fragment event with no post-frame error increase. This is sampled same-host evidence, not physical-phone, independent-network, public TURN, wire-cost or eight-person-call acceptance. The earlier lab route passed public browser credential/CORS and hash-verified TLS data checks; that test route was retired. Fresh public-instance issuance, actual lease rotation during playback, independent-network cold-cache 4K and physical iPhone acceptance on the current revision remain separate gates. Positive peer waits require actual origin timing; a cold loader starts HTTP immediately while cached and late-HAVE peers retain their parallel race. Positive waits are bounded by the segment duration after measured origin recovery time; cached peer races start HTTP immediately and use an explicit peer-only Rust ranged planner with no internal HTTP source. The demo enables lateHaveRace: only native connections accepted at load entry can participate, after an actual exact-object HAVE arrives within the original 2.5-second window. HTTP continues immediately; one holder set is frozen and the deadline never extends. A verified calibration piece unlocks bounded pending work. Four-piece and 512 KiB request caps retain upload burst bounds for larger fragments. At the floor the peer arm cancels while its independent HTTP request continues. Normal buffered mixed transfers retain their HTTP ranges; older modules safely decline the unsupported mode. Range uploads copy the requested bytes across the WASM boundary, rather than the whole 4K object for every range. A separately packaged module Worker reuses the compiled Rust/WASM module for bounded piece scheduling and payload verification; HTTP continues during Worker startup or failure, and leaving the swarm terminates it. The bundle receipt pins the companion source and digest. This separates verification work from playback controls; measured device continuity and useful peer contribution remain acceptance checks. On native-HLS-capable browsers, repeated stalls can switch playback to native HLS; anonymous CORS is set before selecting the approved cross-origin media, peer resources close and native transfer totals are marked unavailable. Native recovery requests playback immediately and restores phase on metadata without a second Play; a later pause or policy rejection stays authoritative. Saved reports retain fixed HLS/native error codes, fallback reason and failed state without arbitrary messages or URLs. Terminal media failure restores Play again. A real Chrome recovery test decoded 333 native 4K frames with zero drops over 13 seconds after an intentional fatal Hls event; the transition interrupted playback for 3.827 seconds. This is recovery evidence, not sustained cold-cache or physical-phone acceptance. The Rust/WASM scheduler exchanges site-verified pieces of the unchanged 4K source, with HTTP completing the remainder, native controls, a Back to live action and shared-room invitation links. Integrity uses a site-pinned HTTPS digest catalogue with receiver-local commitment signing.

Startup took 12.979 / 5.030 seconds. Includes report-export interactions and one retained pre-frame abort; no physical-phone, public TURN, independent-network or competitor advantage claim. - [Failed public pair startup attempt](https://github.com/forgesworn/forgesworn.dev/blob/main/docs/evidence/public-pair-startup-red-20261027.json): 27 October 2026, source cce9807/e910147. Viewer A presented 4K after 4.629 seconds; viewer B reached its one-shot startup deadline without a frame. The planned observation did not complete and this is not a 90-second or 330-second pass. Current terminal startup handling restores an explicit Play retry instead of retrying a permanently failed barrier; it does not resolve the underlying startup deadline or extend the deadline. Saved target/coverage/headroom values describe the last observed diagnostic geometry, not present residency after failure. - [Short public pair diagnostic](https://github.com/forgesworn/forgesworn.dev/blob/main/docs/evidence/public-pair-startup-diagnostic-20261027.json): 27 October 2026, site 03c9c95 and RelaySwarm e910147. Two fresh Chrome profiles with HTTP caching disabled on one M4 completed 90.2 seconds after the second first frame. Accepted peer video was 6.19 MB / 159.19 MB (1.74% / 47.26% of source-plus-peer loaded video), with zero reported post-frame stalls/errors and eight post-frame dropped frames in the second viewer. The second viewer still recorded 309.77 MB of HTTP bodies, including partial/aborted responses, so accepted peer share does not establish equivalent source-traffic savings. This shows useful participation; clean-frame, full-loop, phone, separate-network, public TURN, wire savings and competitor qualifications remain open.
