Maturity
One view of where all 67 components stand. Nothing on this page is maintained here: the phases come from the registry, the migration columns from.altitude/migration.json with their vocabulary read from.altitude/migration.schema.json, and the accessibility column from the same axe report each component's own checks panel reads.
A — is not a no. It means the row has no answer, and every row with one is listed at the foot of the page with the reason.

V2 MIGRATION67 OF 67 TRACKED
STATEMEANSCOUNT
legacyun-migrated (CI rejects feature work)0
dualsupports old + new APIs, requires `expiry`0
scoped-completefully on the new model67
react19True once the React wrapper passes the contract tests on React 19.67 / 67
headlessTrue if the behavior has been extracted into a reactive controller (P5).0 / 67
ssrTrue if Declarative Shadow DOM + Lit SSR is wired and the SSR fixture renders + hydrates without FOUC.1 / 67
The compat budget in .altitude/migration.json allows the legacy aliases — v1 token names and tag suffixes — to be removed in 3.0.0. Until then both spellings resolve; after it, only the v2 one does.
ACCESSIBILITY67 MEASURED · 51 CLEAN · 16 OPEN
Measured means axe ran against this component; clean means it ran and found nothing. Neither is a certification — the screen-reader and keyboard rows on each component's page need a human, and a row nobody has recorded is counted as unrecorded here rather than as a pass.
