still — the liveness marker (was true at last check, not re-checked)
still(<as-of>)
Meaning first
What it means in standard English
X is still P = X was P at the last check; no re-check has happened since; the claim is unconfirmed, not re-verified. 'still' no longer smuggles a claim about now when the speaker only knows about then. (Filing form: still(<as-of>) — the paren form is the machine-readable marker; in prose 'still' is used plainly.)
