Michał Pierzchała f843dc2df1 fix(scroll): keep saturated scroll gestures out of the status bar; gate Android replays from android/emulator (#1781 A1) (#1820)
* fix(scroll): keep saturated scroll gestures out of the status bar; gate Android replays from android/emulator (#1781 A1)

`pnpm gate replay-android` failed 4/8 whenever it ran after the full-tier Android E2E
(replays-nightly run 32107665052, job 95620294899): 05-app-lifecycle, 06-swipe-gestures and
both fixture replays diverged under "A system surface covers the app". The E2E was not the
cause. Reproduced on a pixel_7 / API 36 AVD with the same cutout geometry CI's
`avdmanager --device pixel_7` produces (status bar 136px, not the 63px of a plain 1080x2400
skin):

- `03-scroll-discovery.ad` runs `scroll up 3`. The scroll planner clamps travel to the viewport
  minus a 5% band, so the touch-down landed at y=120 — inside the 136px status bar — and
  pulled the notification shade instead of scrolling. On API 36 the app window is
  edge-to-edge, so the reported viewport starts at y=0 and includes that bar.
- The shade then covered every replay until `04`'s `back` closed it. Native readdir order on
  the runner (03, 05, 06, fixture/02, fixture/01, 04, 01, 02) put four files in that window;
  the last green run (2026-07-30) had 04 right after 03, so the pull was masked.

Fix in the product, not the lane: DEFAULT_EDGE_PADDING_FRACTION 0.05 -> 0.1 in the TS scroll
planner and its Swift port. Every real Pixel has a cutout (5.7% of a Pixel 7's height) and an
iPhone's Dynamic Island status bar is 6.9%, so any saturated `scroll up` opened the shade /
Notification Center for real agents too. Parity vectors updated in both suites plus a Pixel 7
regression vector (1080x2400, amount 3 -> touch-down y=240 > 136).

Second contamination the same order exposed once the shade was gone:
`fixture/02-selector-routes-covered-diagnosis.ad` is a #1715 reproduction recipe that FAILS
BY DESIGN at step 9 (covered-target refusal) and leaves the device in landscape, yet the
gate enumerated `test/integration/replays/android` recursively. iOS keeps gate replays in
`replays/ios/simulator` and fixture recipes in `replays/ios/fixture`; Android now mirrors that:
the six Settings replays move to `replays/android/emulator`, `test:replay:android` points there,
and `fixture/` stays E2E-owned (`full:fixture-replays` already runs 01 by path). android.yml
and the workflow-evidence fixture follow the path; the replay-compat manifest keeps the
historical paths it pins at released tags.

Verified live (Pixel 7 geometry, API 36, --retries 0): control run at main head in CI order
reproduces exactly CI's 4/8; with the fix, `pnpm gate replay-android` 6/6 in both native and
CI order, and `03` leaves Settings on screen (scroll up 3 now touches down at y=240).

* test(scroll): drive the TS and Swift scroll-plan parity vectors from one table (#1820 review)

The two suites hand-mirrored the same vectors and #1820 had to edit both by hand — the drift
class the repo already closes for the tap-point rule via contracts/fixtures/tap-point-policy.json.
The scroll vectors (plus both planner constants, pinned behaviourally on a 1000px axis) now live in
contracts/fixtures/scroll-gesture.json; scroll-gesture.test.ts and RunnerTests+ScrollGesture.swift
iterate it. Verified: vitest 10/10; the four XCTests run on an iOS 26.2 simulator with the unit
flag on (Executed 4 tests, 0 failures).

Also: test/ci/android-workflow-evidence.json says what it guards.

Follow-up for content-safe viewport bounds + discovery order: #1821.
