FA-11428 / Accessibility interaction semantics / Member archive

A removal is announced under an additions-only live policy · case 03

Live-region mutation filtering emits irrelevant event kinds or loses text edits under the default policy.

Member previewVariant 3 · 3 implementations · 6 checks per implementation

Case contract

Events are [kind,text], where kind is additions, removals or text. Policy is None for default additions+text, or a list of relevant tokens; all admits all three kinds. An explicit empty list admits nothing. Return admitted texts in event order without deduplication. This model stops before priority, busy or speech queue scheduling.

Why this case matters

A controlled offline accessibility-data model. It isolates the stated contract; it does not simulate browser accessibility APIs or claim full ARIA conformance.

One recorded failure
