Where every item on Olhão's page comes from: the page it cites, the day that page was read, and a capture of it (a screenshot and its visible text, each with its SHA-256), kept in an sgit vault so the page can be shown as it was, even after it changes.
Provenance
Kept by place.olhao@PrompTugal.dinis, in 5 commits, from 2026-11-15 21:39 UTC to 2026-11-15 23:32 UTC
Signed with the site's own key site.olhao-promptugal; the signature checks
Rests on 15 items citing 10 pages on 4 sites, read on 15 Nov 2026
private for now: the read key is held by data.places@ and given to Dinis; whether to publish it is Dinis's decision (see board/team/data.places/status.json)
How to check
Clone the vault with its read key, then sha256sum the file at the path below: it must give the hash printed here. A capture is the page as the browser saw it, the top 1280 by 1600 pixels, with its text in full.
