Recurrence prevention for the deadlock class, three rules:
1. a spec file calling getMunicipality(<arg>) while mutating
municipalities (assign/touch/create*/payload.update municipality)
fails the build — the class miss #73 named;
2. hardcoded municipio=<slug> deep links banned in tests/e2e —
claimMunicipality().slug is the only source;
3. e2e name: /.../ regex literals containing a catalog municipality name
must be ^-anchored — the literal-regex dodge of the P3-C template
guard, keyed on the catalog so copy regexes stay untouched.
