Quirks
- SNAPSHOT, NOT A FEED: zero derechos formulated 2021+ (the live cadastre has 35,614 such codes, 54%); this bridge re-keys the long-lived titled stock only - state coverage per-asset, never as a headline
- TI_JURNAT forks the id namespace: J = 11-digit SUNAT RUC, N = 8-digit RENIEC DNI; natural persons are dropped and counted, never minted
- TI_JURNAT='J' does NOT imply a valid RUC - 117 juridical rows carry a legacy 8-digit id, so admission requires 11 digits with the '20' company prefix
- NJ_NOMSOC is frozen at snapshot time; never match or mint on it - the RUC carries renames
- one CG_CODIGO can hold several titulars (14,408 fractional TI_PORPAR rows) - the join is one-to-many and first-row-wins would drop co-owners
- EE_ESTAEX='R' rows (26.8%) are 2020 petitorios, an unknown share never titled; their facility ids may not exist in the live cadastre
- SERV_REINFO is a DECOY: its M_RUC is the formalizing OPERATOR, not the titular - never use it for titular re-keying
- www.minem.gob.pe and app.ingemmet.gob.pe time out from non-PE networks; route nothing through them
The Peruvian analog of the ANM-SCM bridge: re-keys name-minted cadastre holders onto SUNAT RUCs, which survive renames (COMACSA → Holcim Perú Agregados keeps RUC 20100037689).
