OPERATOR NOTE — resolves boundary-miss bucket admin:india:district:: (2 misses, chat DWa5bD, 2026-10-07). Sourced by the nightly boundary-miss resolver 2026-10-08.
WHY NOT Survey of India ABDB: state/seeds/IN.json already had ABDB prepared and produced (district dataset nadWtq, 808 units, 2026-08-27) but parked it as a HUMAN LICENCE CALL — ABDB's ISO metadata stamps accessConstraints/useConstraints=copyright and names no open licence, so third-party redistribution by a non-Indian entity was never established (deal-breaker 2). nadWtq was never imported and verify_boundary now reports no metadata anchor: it was reaped as an orphan, so the library had nothing. This NWIC/GSI publication of the same SoI-lineage geometry carries an explicit Government of India reproduction grant and is therefore the licence-clean route to the same target. The ABDB licence question is NOT resolved by this publish — it is simply no longer blocking, and ABDB remains the more current set (777 coded districts vs 733).
ALSO REJECTED: geoBoundaries gbOpen IND ADM2 — its API reports ODbL 1.0 (NOT CC BY 4.0 as IN.json assumed), sourced from 'Pathways Data Pvt. Ltd.' via a private geonode, so it is both share-alike (decision 0012 last-resort gate, which forbids it while a licence-clean source exists) and provenance-weak. GADM v4.1 — 676 units, an under-count, and non-commercial terms. data.gov.in — holds no national SoI boundary product (checked 2026-08-27).
ACCEPTANCE: both retained files joined through the production join path at 96.3% (26/27). The single unmatched key, 'Purba Medinipur', is present as 'Medinipur East' (dtcode 317) — a naming-convention mismatch, NOT a coverage hole.
KNOWN LIMITATION: no alternative-name column. A curated alias column (Purba/Paschim/Uttar/Dakshin forms) would lift name-join rates for Indian district data generally and is a candidate improvement, deliberately not invented unattended.
