Version history
Every published version of this article, newest first. Versions are append-only: a correction adds a row, it never rewrites history. Each version below states what changed against the version before it — which fields moved, and which body lines were added or removed.
The content hash is a SHA-256 fingerprint of that version's stored headline and body, computed when the version was written. Two versions with the same hash hold identical text; a changed hash proves the text moved. It is the tamper-evidence check — recompute it against an exported copy of a version and any silent edit shows up as a mismatch.
How we verify a hash — and how you can
Canonicalization: the hashed bytes are the version's stored headline, then the two characters ||, then the version's stored body markdown — UTF-8, SHA-256, lowercase hex. Nothing else is in the input: no normalization, re-wrapping or rendering is applied first, no trailing newline is added, and no other field (including the parent version's id) is mixed in.
Export a version's stored headline and body, join them with the two characters ||, and take the SHA-256 of the UTF-8 bytes. It must equal the hash printed beside that version. In a shell:
printf '%s' "HEADLINE||BODY" | shasum -a 256-
Version 2
Source update — the underlying public record changed

- The city of Aberdeen posted a document titled [**September 8, 2026 - Agenda for Regular City Council Meeting at 5:30 P.M.**](https://www.aberdeen.sd.us/AgendaCenter/PreviousVersions/1472) to its Agenda Center on Sept. 3, 2026.
- The city's feed timestamps the posting at 17:48 on Sept. 3, 2026, printed as published. The feed labels that time -0600, which is the publishing platform's own default rather than a statement about this city, so it is recorded but not applied. The feed does not name a time zone for that clock. South Dakota spans both the Central and Mountain zones, so the time above is reproduced exactly as the city published it and is not converted.
