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.

+# One round, end to end — the same gates as ship.sh, with the two things that
+# do not depend on each other run at the same time.

+#   bash src-tauri/android/ship-fast.sh [commit-message-file]
+#
+# ship.sh runs the mock walk, THEN the deploy, THEN the phone walk. But the
+# mock walk only drives headless Chrome against dist-smoke/ and the deploy
+# only builds and installs an APK: neither reads the other's output. Running
+# them together takes about four minutes off a round that was taking
+# twenty-three.
+#
+# The one thing they would collide over is vite — two builds racing for the
+# same dependency cache — so the dist-smoke build happens ONCE here, up
+# front, and the walk is told to use it (SS_SKIP_BUILD=1). By the time the
+# deploy runs its own build of dist/ the cache is warm and it only reads.
+#
+# The gate is unchanged in substance: nothing reaches the PHONE that the mock
+# walk did not pass, and nothing is committed the phone walk did not pass. A
+# failing mock walk now costs a wasted APK build rather than a wasted wait,
+# which is the right trade at four minutes a round.
