## Changelog

### 0.1 — 2026-10-09

- First release. Filter-only export of the District of Columbia's contractor Basic Business
  Licences from DC GIS's open "Basic Business License" table (DLCP, refreshed daily): the three
  contracting activities — General Contractor/Construction Manager, Home Improvement Contractor,
  Asbestos Abatement Business. 5,909 active licences / 20,910 in all statuses on 2026-10-09.
  An active export is 3 requests.
- Only the activity and status (fixed strings) go to the server; licence number, name, city, ZIP,
  address state and ward are applied in memory, so no user text reaches the query. ArcGIS's
  HTTP-200 `{"error": ...}` answer is treated as an outage (free `blocked` row).
- One row per licence number (unique on all 20,910 rows). The premises address is kept as filed
  and split into street / city / state / ZIP where it has that shape (20,859 of 20,910).
  `LATITUDE`/`LONGITUDE` are not shipped: they read (39, -77) on every row that has them.
  No phone or email: the source publishes neither, and DC's one dataset that does (the DSLBD
  Certified Business Enterprise list) shares no key with the licence table.
- Looking up licence numbers searches every status unless one is set. `maxResults` (default 500,
  max 100000) is run-wide. Chunked push-then-charge at $0.004 per licence.
