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: what a screen reader says — names, roles, and the sheets out of the tree when they are down
+
+Every control on the phone has a name now, in the app's own words, and the
+desktop's word where it already has one; the nav is a tab set whose badge
+count is part of the tab's name — "You, 3 transfers" rather than a stray 3
+read out before it. The two sheets are dialogs with somewhere sensible for
+the focus to land, and the half sheet's grab handle is finally a real
+Close — the first dismissal a screen reader could reach, because the scrim
+never was one. A sheet that is down is inert rather than sitting
+off-screen in the accessibility tree with the hidden mini bar and the nav
+under it, and one live region is mounted for the life of the app so that
+an undo offer is actually announced; switches say on or off, chips say
+pressed, and the waveform is a slider where it can seek. Nothing visible
+changed. The walk counts the controls with no name, with a junk name, in a
+hidden layer, or with unsaid state — all four held at zero on ten screens,
+and the nameless count on a room and on both prompts besides, which is
+where the six fields named here actually live.
