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
Automated update from the source feed — no human edit
The headline and the body text both changed. (compared against version 1)
Headline at this version: Pierre's Library calendar lists "Makerspace Monday - Pressed Flower Bookmarks" for September 21, 2026
Removed (2 lines )
- The city of Pierre lists [**Makerspace Monday**](https://www.cityofpierre.org/Calendar.aspx?EID=2455) for September 21, 2026 on its Library calendar, with the location given as Rawlins Municipal Library 1000 E. Church St.Pierre, SD 57501.
- The city's feed says it published this entry on 2026-08-26 at 14:51, printed as published. That is when the listing went up, not when the event is. 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.
