 ## Local Completion V2 (2026-09-20)
 Audit outcome in `docs/LOCAL_COMPLETION_V2_REPORT.md`: origin rule invalid → rolled back (35,048); CFOP/IPPT weak-evidence writes rolled back; role no longer inferred from PROD_COZINHA alone; SPED 4.3.x dataset in `docs/sources/`; PIS/COFINS Simples rule from ERP emission evidence; questionnaire V2 (`docs/LOCAL_FISCAL_CONTEXT_QUESTIONS_V2.*`). Rollback tool: `scripts/rollback_field.py`; audit: `scripts/audit_local_writes.py`.
+## Local Completion V3 Operations
+
+Tasks 8-10 are CLI-first and review-first: company/group answers are validated
+locally and emitted as JSON/CSV without import or Firebird writes; `MIXED_OR_DYNAMIC`
+never invents a static entry CFOP; `STORE_IPI_PROFILE` requires an explicit choice
+and produces only a rollback plan. Rollback previews are scoped by run, database,
+field, and product and refuse drift where current differs from the audited after
+value. `scripts/run_local_validation.py` and `scripts/generate_local_health.py`
+are deterministic and emit `docs/LOCAL_PRODUCT_HEALTH_V1.json` with measured counts.
+
+## PRE-AI Local Completion V3 (2026-09-21)
+
+Offline completion is operationally ready. `DeterministicFakeSemanticProvider`
+and the ID-correlated batch runner cover batch sizes 5/10/20 plus contract and
+transport failures; budget, cache-key, dataset-drift, and zero-write E2E tests
+are present. KB conflict audit is conservative: 90 observable GTIN/NCM conflicts
+remain `NCM_CONFLICT`; 73 historical conflicts are explicitly uncovered by the
+seed payload. Canonical identity is deterministic and excludes tenant fiscal
+context. Retrieval V3 evidence hooks exist but V2 remains active until a full
+untouched holdout replay proves no regression. Human/group questionnaire CLIs,
+guarded rollback preview, local validation, and health report are available.
+See `docs/PRE_AI_LOCAL_COMPLETION_V3_REPORT.md` for measured values.
