MC-C1 Brazil base-map generation (regional packages)

Status: generation complete on local disk (23/23 regional packages present); signed distribution, staging serving proof, World/WorldCoasts compatibility and device validation remain pending. Date: 2026-10-27. Base: 394c1389 plus this task. Supervision/evidence time: ~30 minutes; failed first West attempt ran 2,298.64 s before the routing-stage timeout, and the successful West retry took ~2,227 s launch-to-package.

Scope recorded here

All 23 Brazil_* regions were generated with the current scripts/maps/generate-regional-map.sh, --borders 'Brazil_*' and the pinned CoMaps toolchain. Packages stay on local disk under /data/dev/src/comaps-brazil/mwm/; no .mwm bytes are committed. The per-region border setup fell from ~632 s to 14–23 s after the script fix; the times below are full per-region script times, still dominated by features/geometry/search/routing.

The check_mwm diagnostic exits non-zero for these packages; the per-package receipts record check_mwm_exit: 134. This is the known strict-checker diagnostic, not engine acceptance.

West retry

The v2 batch left Brazil_Northeast Region_West as FAIL after TIME 2298.64 / RSS 1837984 because the routing stage exceeded --timeout 1800. The stale work directory was preserved under old-run-20261027/, and the region was regenerated alone with --timeout 3600 --replace.

Retry result: package Brazil_Northeast Region_West.mwm, 185,957,500 bytes, SHA-256 021f0cabeeb44c842eb1c00d9bf1f25c58c3f81215eaee3cbd8c1f539a23d420, check_mwm_exit: 134. Duration was measured launch-to-package as ~2,227 s; peak RSS was not captured for the retry wrapper.
