partitions, but each Dataset retains its Area id, query URLs, checksums, exact
count and measurement-date range.
Before regional activation:
Regional activation now uses the complete checksum-bound municipality
manifest. The Map flow chooses the exact Area partition for a municipality and
uses a bounded multi-Dataset PostGIS query for regional rectangles or the
complete Flanders Area. GeoJSON remains limited to 1,000 rendered features;
counts and configured metrics cover the complete spatial result. Individual
profile dates remain authoritative and no Dataset-level survey date is
fabricated.
Remaining operational follow-up:
- add a governed Flanders boundary manifest and partition coordinator;
- prove idempotent resume and no duplicate VHA `OBJECTID` within a partition;
- benchmark PostGIS point selection and viewport delivery;
- add freshness/version probing for the VHA MapServer;
- keep individual profile dates instead of fabricating one Dataset
`observed_at`.
- keep selection-performance evidence as the profile inventory grows;
- retain explicit no-profile municipalities in every refreshed manifest.
