Liveness

Every listing's most recent code activity — the newer of its last commit and its last release — is refreshed daily. Liveness buckets the age of that timestamp: Active within 30 days, Recent within 90, Quiet within a year, Dormant beyond it. A post on X is news, not maintenance, so it never makes a listing Active; the listing page shows the last news post on its own line. When no commit or release is tracked, no label is shown rather than a guessed one: unknown, not stale.

The label feeds the maintenance component of the Sato Score and is what the directory's liveness badge displays. It is deliberately about observed activity rather than a project's own status field, because self-description drifts and commits do not.

Liveness is not uptime and not quality. A finished library can be Quiet and fine; a busy repo can be Active and broken. It also cannot see private activity, so closed-source projects read quieter than they are.
