The 4K player counted browser-cache responses as fresh source traffic and sought for small shared-clock offsets, briefly interrupting Pixel playback.

Pin RelaySwarm0.4.4 for cached mixed-piece delivery and fetch-backed waits on recorded main media, preserving live seeding coordination. Separate loaded-source totals from browser-reported network/cache response bodies, include measured seek cost in ordinary clock corrections, and require a playable frame before starting stall measurements. Music stays at its original tempo.

Validation:

• 236 Node tests; mocked controller and browser graph regressions cover stale startup frames, real stalls, cache hits and unavailable timings.
• Exact SDK source85bbefa is an ancestor of mergedfdebc64 with an identical tree; all14 SDK hosted checks passed.
• Physical Pixel/Vanadium and M4 Chrome played original2160p through private expiring SpryTLS profiles. The scoped cached-browser run verified14,925,824 peer bytes in101.9s with no dropped frames; its recording-loop buffer wait remains counted.
• The unchanged M4 live-broadcast fixture passed both qualities and producer reconnect:3.42MB verified peer delivery across6loads; consumer and origin-only baseline reported no stalls.
• The strict cold-cache4K check remains failed:245,760 verified peer bytes and one1.64s wait in101s. First-visit efficiency and continuity need further work.

Qualification profiles stay private. Automatic public TURN credential delivery and physical iPhone acceptance remain separate.
