Maintainer impact

The reduced-motion mouse-close contract intermittently fails because the test's untimestamped five-step mouse drag depends on event delivery speed. CI run 42518970572, job “Accessibility spec-test contracts (5/6)”, at ac0046c failed expect(dialog).toBeHidden({timeout: 2_000}): Expected hidden, Received visible.

A delayed synthetic stream lowers the mouse release velocity, or zeroes it after the tracker's stillness interval. The 150 px drag then snaps back instead of projecting past the dismiss line, so the test never exercises its intended closing behavior.

Intended invariant and change

No behavior change. Reuse this file's existing timestamped CDP mouseDrag helper. Keep the downward mouse gesture and 150 px travel, pin it to 50 ms (3,000 px/s), and release 1 ms after the final move. The mouse projection remains on the intended dismissal branch: travel exceeds the 48 px projection floor, and 150 + 3 × 499 = 1,647 px passes the dismiss line. The original input had no specified duration; this chooses a representative fast mouse release, not a longer drag or a different product path.

This follows AST-100 FR4's event-time velocity contract and keeps BottomSheet FR15 / reduced-motion DR1's no-travel assertions. Every assertion and timeout remains unchanged. No component, story, runner or workflow changes.

Evidence

deflake_evidence: b. It went red in 2 streaks in 7 days (2026-11-08T05:23Z, 2026-11-08T20:32Z), passing between them.

Successful CI run 42503506547 at c08de54 occurred between those streaks. Later successful run 42533992004 at c590f9b contains the failing commit, verified by git merge-base --is-ancestor.

Local tests use base 15098bc, with a freshly built Storybook and the pinned Node/pnpm versions. The BottomSheet sources, this test and VelocityTracker have no changes between the failing commit and that base.

Before the fix, replacing the original mouse.move(..., {steps: 5}) with five 30 px moves and a 200 ms delay after each move reproduced the same hidden-dialog failure in 2/2 runs (--repeat-each=2 --retries=0). Only the synthetic input cadence changed.

After the fix, normal delivery passed 20/20 (--repeat-each=20 --retries=0). Adding a 200 ms delay before every CDP mouse event, including release, while retaining the pinned timestamps also passed 20/20 with the same command. All failure-injection delays were removed from the final change.

Scope

• No intended public API, product behavior, visual direction, or policy change.
• No product changes, weakened assertions, longer waits, or retries.
• Public text contains no private operational context.

This test passed on main since, but it failed intermittently (BottomSheetRelease.a11y.chromium.spec.ts › a mouse close under reduced motion moves the sheet no further: red at 2026-11-08 05:23 UTC, 2026-11-08 20:32 UTC); this PR fixes the intermittency.
