android: the handoff — the pending rounds, the pipeline, and what is unverified

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.

+android: the room can measure the song, and a cold artist page stops waiting on one call
+
+The tap-to-sync room draws the recording's own vocal band
+(lyrics_vocal_activity, the desktop's coarse envelope) as a strip under the
+head, and one button lays every line across the stretches it says are sung —
+the desktop's own generator, shared and unit-tested, which refuses rather
+than guesses when there is too little voice to read. The result is labelled
+an estimate everywhere it shows, the cursor goes back to the top so the taps
+correct it, and one more tap drops the whole thing back to an empty set,
+because a rough fill stamps every line at once and leaves Undo nothing to
+take back. The artist page now fires the hero seed and the overview beside
+the full page, the way the desktop stages them: a hero Kyle picked on this
+phone comes back off the file with no network at all, the discography paints
+from the overview's first page until the exhaustive pass lands with the
+classified one, and both lanes are dropped with the page when a hero
+changes. ANDROID.md's "Not done yet" is rewritten as the true map of the
+port — what is absent by design and why, what is waiting on Rust rather than
+on a file picker, and one bullet about the artwork viewer that had been done
+for rounds.
