Maintainer impact

The release check on main fails "Accessibility spec-test contracts": all 17 InfoTip audit cases stop at InfoTipAudit.a11y.chromium.spec.ts:444, "button 0 (sm) grows under a fine pointer: auto auto auto auto". It started when #8085 merged, right after the audit landed in #9940; main just before #8085 passes all 17.

Intended invariant

component:InfoTip AR1: under a coarse pointer the button reaches 44 px through an invisible hit area; under a fine pointer the button keeps its own box (spec:AST-094 FR42). The audit checks that the hit area does not grow under a fine pointer.

Change

The audit read the button's ::after insets and required each to be 0. That fit InfoTip's earlier hit area, which set the insets for every pointer. Since #8085, InfoTip uses the shared touch layer, which gives the ::after its content, position and insets only under a coarse pointer. Under a fine pointer the ::after has no content, so it draws no box: there is no hit area, and its insets read auto. The audit now reads the insets only where the ::after has content, and still requires 0 there. The product is unchanged.

Why the audit and not the product: auto here belongs to a pseudo-element that draws no box, so no user can reach it. Setting the insets to 0 would put back a box the layer does not draw, only for the audit to read.

Evidence

Chromium, the InfoTip Sizes story, main e657e2e against main before #8085 (38f1a1d):

• Under a fine pointer on main, each button's ::after reads content none, position static, insets auto, and a point 3 px outside each edge hits the page, not the button. Before feat(List): a row's touch target grows toward 44 px where its neighbors leave room #8085 it read content "", position absolute, insets 0px, with the same hits. Under a coarse pointer both read the same band (for the sm button: -14 px, -8 px, -14 px, -14 px), and points 3 px out hit the button.
• Failure before the change: main fails 17 of 17 cases with "auto auto auto auto"; main before feat(List): a row's touch target grows toward 44 px where its neighbors leave room #8085 passes 17 of 17.
• Success after the change: 17 of 17 pass.
• A hit area that grows still fails: with InfoTip's ::after grown 4 px under every pointer, all 17 fail with "-4px -4px -4px -4px".
• Product/runtime behavior verified unchanged: the diff is one test file.
• CI impact: none; no workflow or CI script changes.

Scope

• No intended public API, product behavior, visual direction, or policy change.
• Product changes discovered during the work were removed or split.
• Public text and artifacts contain no internal Meta context.

Approved pending CI: CI has not run on this head yet.

The audit now skips the inset read only where the button's ::after draws no box and still fails a hit area that grows under a fine pointer, which matches component:InfoTip AR1 and spec:AST-094 FR42; InfoTip itself is unchanged.

Next step: mark the pull request ready for review, and a maintainer adds the ci:run label so CI runs (the label takes effect on the next push or a close and reopen).
