The 49,358-byte source file is unchanged. Rendering uses Mercator projection and
custom neutral styling. Source province codes repeat for newer Papua provinces;
rendering identifies geometry by unique province name, not by those codes.
This is simplified illustrative geography, not a survey or jurisdiction map.
The publisher mentions SOURCE.md in its license, but that file was unavailable
(HTTP 404) at retrieval. No more specific upstream provenance was supplied.

## Polda catalog

Names/headquarters-city references, independent of the province dataset:
https://www.polri.go.id/tentang/satuan-wilayah
https://eppid.polri.go.id/e-ppid-polda
https://tribratanews.polri.go.id/blog/nasional-3/polda-papua-barat-daya-resmi-beroperasi-82804
https://tribratanews.papua.polri.go.id/kapolda-papua-tengah-pimpin-pelantikan-pju-polda-papua-tengah-dan-sertijab-dua-kapolres/

The catalog has 36 entries, including Papua Tengah and Papua Barat Daya.
Coordinates are approximate headquarters-city positions manually curated for
this national-scale visualization, not official building coordinates.
Jurisdiction descriptions are broad summaries, not rules for assigning users.
Metro Jaya overlaps province-level geography; Papua covers multiple provinces.
No institution membership is inferred from geography. No official insignia used.

## Performance data

All initial scores, participant counts, rank movement, and the example user's
region are deterministic illustrative fixtures for one simulation, not official
results or a real-time feed. Scores use 0–100. Equal scores sort by stable Polda ID
for deterministic demo ordering. No backend province rankings are reinterpreted.
