6d28d6994a1f  AX: VoiceOver repeats the first sentence over and over as content streams in on gemini.google.com

Classified as not security-relevant.
Triage note: AXLiveRegionManager feature work: empty-region settle timer, aggregated-text caching, word-boundary/punctuation handling and streaming re-render matching, with defensive caps (maximumAggregateLength, maximumSnapshotObjects) and CheckedRef captures. Accessibility announcement behavior, not a fix of a concrete reachable memory-safety bug.
This commit was flagged by the signal scorer and reviewed by AI (not a human). It is listed only so the triage is auditable; there is no root-cause analysis because this is not a vulnerability fix.
