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

    • Work includes pavement repair in the driving lane southbound until further notice. Concrete repair planned for 11/12 with lane closure.
    • The listed work zone is at I-29 S 2.25 miles north of the Interstate 90 junction north of the Sioux Falls exit \(Exit 84\), near milepost 86.

    • Drivers heading south on I-29 north of Sioux Falls will find the driving lane closed near Exit 84. The closure sits 2.25 miles north of the Interstate 90 junction. Crews are doing pavement repair work in the southbound driving lane, and the South Dakota Department of Transportation says the work will continue until further notice. Pavement repair fixes cracked or broken concrete in the road surface, work that often requires closing a lane so crews can work safely. The department lists the project.
