Permission-aware tree branch projection: Redacted branch enters selectable row set · case 05

Redacted branch enters selectable row set produces the wrong hierarchical widget state in a regression fixture.

Member previewVariant 5 · 3 implementations · 6 checks per implementation

Case contract

Denied branches suppress descendants even when descendants grant access. A denied branch itself may remain a nonselectable redacted row if a summary is allowed. Metadata counts exposed siblings only, and active focus never references a redacted row.

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.

One recorded failure

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
redaction	`[["r", "a", "s", "v0", "v1", "v2", "v3", "v4"], ["a", "s"], ["a"], {"a": "Restricted branch", "r": "r private", "s": "s private", "v0": "v0 private", "v1": "v1 private", "v2": "v2 private", "v3": "v3 private", "v4": "v4 private"}, "a", {"a": 1, "r": 7, "s": 7, "v0": 7, "v1": 7, "v2": 7, "v3": 7, "v4": 7}]`	`[["r", "a", "s", "v0", "v1", "v2", "v3", "v4"], ["s"], [], {"a": "Restricted branch", "r": "r private", "s": "s private", "v0": "v0 private", "v1": "v1 private", "v2": "v2 private", "v3": "v3 private", "v4": "v4 private"}, "r", {"a": 1, "r": 7, "s": 7, "v0": 7, "v1": 7, "v2": 7, "v3": 7, "v4": 7}]`	Failed
