FA-11170 / Streaming segment lifecycle / Member archive
Segment append must finish before next · case 05
A second append is started while the previous asynchronous append is still active.
Case contract
Schedule at most one source-buffer append: when busy retain queue; otherwise dequeue its head. Return [scheduled ID or None,pending].
Why this case matters
A deterministic local media controller stage; metadata and downloaded data are supplied explicitly. No external player, service or codec is required.
One recorded failure
