Everything written this session that has not been through the device: rounds 43 to 48 (each patch adversarially verified, 43's transient-notice expectation fixed), a partial round 49, the pipeline scripts, the Android Auto design and the icon comparison mock. Also the two harness changes that were never A/B'd — adaptive waits, which may only shorten a declared wait and never lengthen it, and a ship that runs the mock walk and the deploy at the same time. The A/B and its 255-step baseline are in handoff/tools; main stays at what the phone has actually walked.

/* THE QUEUE WINDOW. Every update carries a bounded slice of the queue —
|
|
the current item and QUEUE_WINDOW either side — because media3's
|
|
SimpleBasePlayer.getState() wants a playlist and an index into it, and
|
|
the migration to it should find this data already running rather than
|
|
written the same day. Nothing reads it yet: MediaService ignores both
|
|
fields and the card is exactly the card it was.
|
|
|
|
TEN either side, twenty-one entries at most. One would cover the card's
|
|
own prev and next and nothing else; a queue LIST — which is what Auto
|
|
asks for — wants a screenful plus a scroll in either direction, and a
|
|
car's list pages about five rows, so ten is two of those each way. It is
|
|
a CAP, not a length: a two-thousand-track queue crosses the bridge as
|
|
twenty-one entries exactly like a twenty-one-track one does. Measured at
|
|
two kilobytes of JSON for twenty-one short titles and six with long ones
|
|
and real Android cover paths — against the thirty to eighty kilobytes of
|
|
base64 cover that already ride this same call once per record, and an
|
|
update is a track change, a transport change or the thirty-second top-up,
|
|
never a position tick. */
