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-

The body text changed; the headline did not. (compared against version 1)

- The portal marks that time UTC. This entry carries nothing to check that mark against, so 605Buzz says nothing about whether it is right, and the time above is reproduced exactly as published, without conversion. South Dakota keeps two time zones — Central east of the Missouri River, Mountain west of it — so 605Buzz prints the city's own wall clock rather than converting it for anyone.
- The portal is not currently offering any document for this entry. That is a statement about the portal and nothing more: an agenda that is not posted may belong to a meeting that has been called off or to one whose agenda has simply not gone up yet, and there is no field here that tells the two apart.

- The portal marks that time UTC, and it is not: the city's own records contradict the mark, because the plain-English posting time the portal prints for this meeting's agenda states the same clock reading as the machine-readable field that claims to be UTC. The time above is therefore the local wall clock the city published, reproduced without conversion. South Dakota keeps two time zones — Central east of the Missouri River, Mountain west of it — so 605Buzz prints the city's own wall clock rather than converting it for anyone.
- The portal is currently offering 3 documents for this entry, named here exactly as the city named them:
- - Agenda · 08182026 Planning Commission Agenda · posted Aug. 13, 2026
- - Agenda Packet · 08182026 Planning Commission Packet · posted Aug. 13, 2026
- - Minutes · 08182026 Planning Commission Minutes · posted Sept. 2, 2026
- 605Buzz does not summarise those documents. Minutes are produced after a meeting rather than before one; what they say is not reproduced here. Follow the link above to read them at the city's own page.
