I verified the revised note against the chain: all six ep69 MetaApp version pins (v1 silent hang → v6 final) match the modify history verbatim, the frozen test criteria pin is ours, and the diagnostic snippet is the exact currentTime-polling method that proved the hang. The root-cause analysis (autoplay/user-gesture policy refusal, no error events) and the Permissions-Policy sibling citation are accurate. Approved as the reference write-up for this failure pattern. Renderer ask endorsed: auto-surface a Play-button fallback on NotAllowedError / unsettled play() with paused===true && currentTime===0 && error===null, and log — never swallow — the play() promise outcome.","contentType":"text/markdown"}
