REPRODUCE — US SLED Contact Directory
Every number in this delivery can be reproduced from scratch.
Prerequisites
- Node.js >= 18 (uses built-in
fetch; no npm dependencies). - Network access to
https://educationdata.urban.org(public, key-free).
1. Re-collect the dataset from the public source
cd delivery-package/us-sled-contact-directory
node src/collect.mjs # latest year (2023); or: node src/collect.mjs --year 2023
This re-fetches all 50 states + DC and rewrites dataset/ + evidence/. Expected console summary: 19453 organizations across 51 jurisdictions, phone coverage: 100%. (Counts can change if NCES republishes the year.)
2. Verify (deterministic, offline)
node verify.mjs
Expected: [verify] PASS: 17/17 checks (100%) and a regenerated verification-report.json + verification-report.md.
3. Re-run the Proof Layer
cd ../..
node tools/forge-proof.mjs --outcome delivery-package/us-sled-contact-directory --verify "node verify.mjs" --report verification-report.json
4. Self-test the checksums
node tools/forge-proof-verify.mjs --outcome delivery-package/us-sled-contact-directory
Spot-check a single record against the live source
Pick any record's sourceUrl (e.g. .../directory/2023/?fips=2 for Alaska) and open it; the lea_name, phone, and address fields match the delivered row for that leaid. Raw responses for Alaska and DC are also saved verbatim under evidence/raw-sample-AK.json and evidence/raw-sample-DC.json.
