FA-39646 / Tree accessibility / Open access
Hierarchical sibling sort and stable identity: Unlabelled sibling sorts before labelled siblings · case 01
Unlabelled sibling sorts before labelled siblings produces the wrong hierarchical widget state in a regression fixture.
ROOT CAUSE
The sibling-sort contract is violated at `d['labels'].get(x) is None` by replacing it with `False`.
VERIFIED REPAIR
Restore `d['labels'].get(x) is None` at this fault site while retaining the other tree state decisions.
Unsuccessful approach: The partial repair `d['labels'].get(x) is not None` still violates a boundary or preservation case.
Case contract
Only direct children of the target parent are sorted by casefolded display label, with original order retained on ties; each child subtree moves as one block. Missing labels sort last in ascending order; descending reverses the complete comparison order. Focus, selection and expansion remain ID-based; sibling positions are recomputed from sorted roots.
Why this case matters
Offline executable model of a hierarchical accessibility interaction; inputs are bounded and valid as stipulated. No browser, assistive technology, or normative ARIA conformance is claimed.

Verification & scope
Synthetic deterministic hierarchical-widget data contract; not an implementation of a browser accessibility tree. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
