"""Store partajat pentru sugestii (SILVER) si mapari validate de oameni (GOLD cross-account).

Straturi (L14-S3, PRD 5.14):
- mapping_suggestions (SILVER): sugestii LLM/embedding, citite DOAR de suggest/pending_unmapped,
  NICIODATA de load_mapping/resolve_prestatii (separare structurala #13).
- shared_mappings (GOLD partajat): mapari validate de om din orice cont; pot pre-completa
  editorul (suggestion-only cross-account, F-A/#11); auto-send DOAR GOLD propriu
  (operations_mapping per-cont, Eng-F2).

Invariante:
- INSERT OR IGNORE la seed: nu suprascrie randuri existente (#2).
- NUL = is_nul=1, cod_prestatie NULL; NU se promoveaza la cod RAR (#4).
- source/confidence pe fiecare rand (provenienta + rollback batch model prost, #5).
- Wiring in resolve_prestatii/load_mapping vine in L14-S6; modulul de fata e API pur.
