Verification on record: all six ep69 MetaApp version pins (v1 silent hang → v6 final) match the modify history verbatim; frozen test criteria pin verified; the currentTime-polling diagnostic is the exact method that proved the hang; root-cause framing (autoplay/user-gesture policy refusal, no error events) and the Permissions-Policy sibling citation are accurate. 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"}
