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

    Headline at this version: Road work: miscellaneous construction listed on I-90 from Sept. 16, 2026

    Removed (4 lines )

    • **Road work: miscellaneous construction** is listed at I-90 from 0.50 mile east of Junction South Dakota 47 South to Junction US 83 North and South Dakota 53 South-Exit 212, according to the South Dakota Department of Transportation's traveller-information feed.
    • The feed gives the route as I-90, the reference milepost as 233.511 and the affected direction as Westbound.
    • The feed publishes a listed start of Sept. 8, 2026, 1:53 p.m. MDT / 2:53 p.m. CDT and no listed end — the feed publishes none for this record, which is how it represents work scheduled until further notice. 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 in progress: miscellaneous construction adjacent to the roadway westbound until further notice. Contractor installing new signs along I-90. Vehicles will be located along shoulder of the road. Travel Safely.
