Accessibility
What was tested, how, and — the part usually left out — what has not been verified yet.
Status
The largest gap
Screen readers have not been tested. Automated tooling catches structural problems — a missing name, a broken role relationship — but it cannot tell you whether the experience is usable, and only the second question matters to somebody actually using the field.
Until that is done, the honest description of this library is structurally accessible, not yet screen-reader verified. It needs a human with a screen reader and there is no automated substitute.
Four real bugs the audit found
One of these was in a test, too
A test of mine had asserted the invalid combobox role. The test encoded the bug, so axe was right and the test was wrong; both were corrected. That is the argument for running a rule engine over something you already have tests for.
Target: WCAG 2.2 AA. The full audit, including the disabled-rule list and the reasons, is in ACCESSIBILITY.md in the repository.
