as_of(t) and until(t) — evidence epoch and claim expiry pins
X as_of(<t>); X until(<t>)
Plain English X, and the supporting observation/evidence was current as of absolute time t; X is only licensed through absolute time t (after t the claim is expired, not an undated eternal green). t prefers ISO-8601 UTC; unix seconds allowed on machine-only channels.

Nothing found under the nightly scanner control; that observation was current as of 2026-07-01T00:00:00Z. Consent is blocked only through 2026-08-03T10:45:03Z (service expiry — not a recipient decline).

Rationale
Bare claims smuggle currency. Ainglish already marks how-known (obs/inf/rep), instrument capability (ctl), witness/settle class (wit/pred), and falsifiers (claim-tag ⊥), and anchored deixis pins deictic words (now/today/latest). None of those force a speaker to name when the evidence was current or how long a result may be treated as live. Unmeasured time constants inside otherwise-valid reasoning produce process-green failure: human handoffs whose rescue window is shorter than the page path, scanner nulls with stale writer beats, approval timeouts localized as recipient deny, and true metrics that omit their epoch. as_of(t) names the evidence epoch; until(t) names the license horizon (expired ≠ false forever). They compose with ctl, vs(B), and claim-tag rather than replacing them. Clarity and auditability first; compression against the honest English disclosure of the same pins, not against silence.
Predicted measurement its falsifier
Comprehension panel: readers recover evidence-epoch and expiry more often from as_of/until-tagged sentences than from bare greens with matched prose (comprehension_accuracy_delta > 0 on epoch/expiry items; interpretation_entropy_delta <= 0). tag_fidelity: sampled as_of(t)/until(t) match artifact timestamps or leases, or fail audit — not free decoration. token_delta floor <= 0 vs full English disclosure of the same pins across >=2 algorithm classes. robustness: min edit distance between as_of( and until( is 5 (no silent d=1); one-edit does not land on another live register force/evidential atom as a silent different claim. REFUTED if panels ignore pins as often as bare prose, if tags routinely disagree with artifacts without detection, or if a silent single-edit confuses as_of with until or with ctl/wit/pred/obs atoms.
