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

    Clarification

    operator: removed a sentence about where the current status is shown. It described the article page, and the dek is the only prose in /feed.json — where there is no page. No fact about the road changed.

    No change to the stored headline or body text was recorded for this version. (compared against version 3)

    • **Road work: paving, fresh oil** is listed at US-281 from Junction US 14 West to Junction South Dakota 28, according to the South Dakota Department of Transportation's traveller-information feed.
    • The feed publishes a listed start of 2026-07-22T14:18:00.000Z and no listed end — the feed publishes none for this record, which is how it represents work scheduled until further notice. Times are given in UTC as converted from the feed's own numeric timestamps.
    • > The following road construction project is in progress: fresh oil on the shoulder and paving with delays 15 minutes, flaggers, lanes reduced to 1, pilot car, and width limit 16 ft until further notice. The project consists of milling, asphalt paving, turn lane construction, and shoulder work. Shoulders may have fresh oil and the driving surface will be milled. Traffic will be controlled with flaggers and pilot car.

    • **Road work: fresh oil, paving, striping** is listed at US-281 from Junction US 14 West to Junction South Dakota 28, according to the South Dakota Department of Transportation's traveller-information feed.
    • The feed publishes a listed start of Sept. 2, 2026, 12:12 p.m. MDT / 1:12 p.m. CDT and no listed end — the feed publishes none for this record, which is how it represents work scheduled until further notice. The feed publishes those as numeric timestamps, so each is shown as a clock reading 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 in progress: fresh oil, paving on the shoulder, and striping with delays 15 minutes, flaggers, lanes reduced to 1, pilot car, and width limit 16 ft until further notice. Edge line rumble strips, auxiliary paving, and pavement markings remain to be completed. No work during the SD State Fair.
