MC-B1 correction rules

Status: LOCAL_DONE. Date: 2026-10-27. Base: f6abff83 plus this task. Time: ~15 minutes.

Delivered

docs/product/STATION_CATALOG.md now carries B-BR-COR-01..08 before any code:

• target and one-field-only corrections against an existing station UUID;
• official/community separation (D8): official facts and canonical identity are never overwritten; accepted locations become reviewed revisions and other accepted fields become labelled community assertions;
• signed free-account proof, 20/day quota, one open correction per account+station+field and idempotency semantics;
• per-field validation, Brazil/municipality bounds, coarse proximity bucket only and no contributor GPS;
• consensus, auto-verification and reviewed decisions with mandatory reasons;
• the frozen status lifecycle pending, auto_verified, accepted, rejected, expired, cancelled, superseded, frozen;
• privacy/erasure, evidence expiry, text/PII rejection and abuse/audit rules.

Verification

• Documentation-only change; no runtime or migration.
• git diff --check clean.
• The field list in this batch is location, display name, brand, address and operating status; dossier and EV fields join after MC-A5/MC-A8.
