Action labels are replaced by internal operation names.

Case contract

Input actions [id,label,enabled,exposed,requires_confirmation,kind,priority], plus permission and locale label overrides. Omit unknown kinds (only invoke, expand, collapse, increment, decrement), disabled or unexposed entries. Destructive confirmation-requiring actions need permission. First eligible occurrence of an ID wins; sort by ascending priority preserving ties. Label is override if key exists (including empty), else authored label, else kind. Return [id,label,kind,requires_confirmation]. This only describes platform actions and never activates them.

Why this case matters

Offline accessibility bridge model with explicit policy; useful for testing semantic API adapters independently of browser implementations.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
ordered descriptor set	`[["y", "expand", "expand", false], ["z", "collapse", "collapse", true], ["x", "Localized4", "invoke", false]]`	`[["y", "expand", "expand", false], ["z", "Close", "collapse", true], ["x", "Localized4", "invoke", false]]`	Failed
