# 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.
