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.

/* Five reads that never depended on one another. Each is a
|
|
spawn_blocking SQLite read behind the library's single
|
|
`conn: Mutex<Connection>`, so the queries still take their turn —
|
|
what is saved is five bridge round trips collapsing into one.
|
|
|
|
Every call keeps the handling it had. The one thing that could have
|
|
moved is `lib.error`, which has two writers and used to be settled
|
|
by the order they were awaited in; the two messages are carried out
|
|
of the round and applied in that same order instead, so a failing
|
|
library still shows the library's message and not app_status's, no
|
|
matter which of them answers last. Nothing is dropped, nothing new
|
|
is asked for, and `lib.loaded` still goes up only once all five
|
|
have settled. */
