No automated guard that removed islands have zero SEN connections

apps/web/public/atlas/data/atlas.json

The commit's claim is factually correct per public CENACE/CFE docs, but there is no test to catch misclassification if future commits re-add islands.

Occidental holes (rings 1–3) are inland water bodies, not topological errors

apps/web/public/atlas/data/atlas.json

The 4-ring Occidental polygon's holes center inside Lago de Chapala, Lago de Pátzcuaro, and highland basins — geometrically valid. Ring count decrease 5→4 reflects polygon removal, not ring removal.

Peninsular 2-polygon structure correctly represents Cozumel on SEN

apps/web/public/atlas/data/atlas.json

Polygon 1 centroid confirmed at lat≈20.43, lon≈−86.87 — correct for Cozumel. Retention justified by submarine cable SEN connection.

Islas Marías removal from Occidental is geographically consistent

apps/web/public/atlas/data/atlas.json

Islas Marías falls west of Occidental's outer longitude boundary (−105.76W), confirming it was a separate polygon correctly excised.

No X-Content-Type-Options header for public static JSON (pre-existing)

apps/web/public/atlas/data/atlas.json

Not introduced by this diff. Vercel serves with correct MIME type; a nosniff header would be belt-and-suspenders hardening.

No CHANGELOG or data-version signal for open-source dataset consumers

apps/web/public/atlas/data/atlas.json

atlas.json is published as MIT open-source data. Downstream consumers who pin the file have no in-file version marker to detect this semantic change.

Generation script or source dataset not referenced in commit message

apps/web/public/atlas/data/atlas.json

Commit explains intent but not the tool/command used to regenerate polygons, making future regeneration harder to trace.

No schema validation test for atlas.json

apps/web/public/atlas/data/atlas.json

A lightweight Vitest fixture (~20 lines) asserting required top-level keys, RP keys match REG set, all coords within Mexico bounding box, and rings have ≥3 points would prevent silent data regressions on future polygon edits.

Island-exclusion rule undocumented in any generation artifact

apps/web/public/atlas/data/atlas.json

Rule (keep only main contiguous body; exception: SEN submarine-cable islands) exists only in this commit message. Codifying in the atlas-sen generation pipeline would prevent regression on next data rebuild.

Cozumel polygon has no visual or data distinction from mainland Peninsular

apps/web/public/atlas/data/atlas.json

Both Peninsular polygons render identically. A boolean island_connection field could let the map render a dashed outline or tooltip explaining the submarine cable.

No embedded provenance or generation timestamp in atlas.json

apps/web/public/atlas/data/atlas.json

A top-level _meta key or sidecar atlas.meta.json with generated date and source commit would let future maintainers quickly audit whether the island-exclusion rule was applied.

centerRegion() bounding-box fit includes Cozumel, widening Peninsular zoom slightly

apps/web/public/atlas/data/atlas.json

Minor UX quirk. A primary: true flag on the mainland polygon in the generation script would let the map zoom to the mainland first.
