Separate when something happened, was published and was observed
A source may describe an earlier event, publish it later and be observed later still. Those dates answer different questions. Confusing them can shift a timeline and create an impression of recency that the source never claimed. A temporal reading preserves available dates with their meanings and leaves dates unknown when the material does not supply them, rather than filling gaps by intuition.
Evaluate currentness against a defined moment
Currentness needs a reference instant and a policy with explicit criteria. Under a versioned policy, an observation may move from CURRENT to STALE and then HISTORICAL as time passes. These transitions describe its usefulness for present questions; they do not change the original content or establish that the claim stopped being true. UNKNOWN remains unknown until new governed evidence changes what is known.
Reobservation adds evidence and preserves history
Recovering support for the present may require observing the same claim again or asking a different question. A reobservation has its own time and provenance and is appended to the history; it does not silently replace the earlier record. Comparing the observations requires checking that they concern the same subject and scope, and explaining any source, method or condition change that affects interpretation.
Do not turn age into a verdict
Old evidence may be decisive for understanding a historical sequence even when it cannot describe the present situation. A recent source also does not automatically resolve identity, coverage, authority or contradictions. Currentness combines with evidential strength, provenance and scope; it should not be compressed into total certainty or confused with permission to reuse data in every context.
Conceptual example
Hypothetical: a catalog observed years ago lists a product line. It may support that the representation existed when the catalog was captured. Establishing that the line remains available on the date of the question needs suitable evidence for that time. The old catalog does not become false; its ability to support a present claim is different.
Scope and limits
Age thresholds depend on an explicit policy and the kind of claim; there is no universal duration for all evidence. Currentness does not prove truth, and temporality does not grant reuse permission. Missing dates remain UNKNOWN. AXIGNAL should not invent an end event or present a historical observation as current state without additional support.
