**Evidence** (a page reported by its own publisher, kept as we read it). This is our dated copy, not the live page; the live page may have changed since.

| Against the capture before | the hash of the visible text differs from 11 Nov 2026, 03:24 UTC, but read by the archivist: **same content**. The same communiqués and news items; in this load three news dates were printed in the script's raw form ('Tue Nov 10 08:00:00 UTC 2026') instead of '2026-11-10'. |
| Ignored when comparing | IPMA's pages print the time of the visit (for example '03h24m UTC:'), the warnings timeline prints the hour labels of its time axis, and the news list prints its dates in one of two forms depending on the load ('2026-11-10' or 'Tue Nov 10 08:00:00 UTC 2026'): all three are ignored when judging whether the page changed. |
