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 feed publishes a listed start of Sept. 23, 2026, 6 a.m. MDT / 7 a.m. CDT and a listed end of Sept. 23, 2026, 5 p.m. MDT / 6 p.m. CDT. Each is one instant shown in both of South Dakota's zones — Mountain first, Central second; they are the same moment. The feed names a route and not a zone, so 605Buzz does not pick one for you.
- > The following road construction project is scheduled to begin: from 6:00 AM MDT Wednesday, September 23, 2026 maintenance with flaggers, lanes reduced to 1, and width limit 15 ft until 5:00 PM MDT Wednesday, September 23, 2026. SDDOT crew performing routine inspection and maintenance.

- **Road work: maintenance** is listed at SD-20 from 0.50 mile west of Mobridge to Mobridge, according to the South Dakota Department of Transportation's traveller-information feed.
- The feed's route field and its location description do not agree on this record: the route reads US-12 while the location description begins "SD-20 from 0.50 mile west of Mobridge to Mobridge". Both are reproduced as published rather than reconciled.
