# A minimum evidence packet for a public timeline claim

Before publishing a concise timeline statement, assemble a small packet that lets another reader test exactly what is being claimed. The packet is deliberately narrow: it records support without pretending that a single page settles every question.

1. Claim text: write one bounded statement and name the time field it concerns.
2. Source identity: retain the requested URL, final URL after redirects, publisher name when shown, and the page title.
3. Observation record: note the retrieval time, HTTP result or visible access state, and a content fingerprint or preserved excerpt location when practical.
4. Support mapping: distinguish words directly stated by the source from any inference needed to connect them to the timeline claim.
5. Limits: identify missing date fields, competing sources, changed pages, access failures, or scope differences that prevent a stronger conclusion.
6. Recheck trigger: state the concrete new source, correction, restoration, or age threshold that requires a fresh review.

The packet should preserve event time, source publication or update time, and reviewer observation time separately. A page becoming unavailable later is a new retrieval observation; it does not erase the earlier observation or prove why availability changed.
