Missão 4 / Bloco A.1 (prioridade máxima): central.app.field_contract.infer_role treated ANY C000032.TIPO=COMPOSICAO row for a product as proof of own production, with no ratio check - a beer sold 19 times and used once as a recipe component (Agent 2, real data) was classified OWN_PRODUCTION from that single occurrence, proposing to change its CFOP and IPPT. New deterministic threshold in field_contract.py: COMPOSICAO must be a majority (>=70%) of that product's own C000032 movement history, with at least 5 total events, to count as own-production evidence. Below 30% the evidence is discarded entirely (falls through to other role evidence, e.g. TIPO=VENDA -> RESALE). Between 30% and 70% (with enough events to be meaningful) is genuinely conflicting evidence -> UNKNOWN, never guessed either way. RECEITA_INGREDIENTES/PROD_COZINHA-based evidence (a direct recipe-table linkage, not a statistical ratio) is untouched. agent/src/gti_fiscal_agent/firebird_reader.py now counts COMPOSICAO vs other C000032 rows per product (read_product_evidence: single indexed query; read_evidence: one grouped query for the whole catalog) into a new ev["composed_ratio"] key, alongside the existing "composed" set (kept for other, non-role consumers like coverage.py). central/app/enrichment/api.py's sanitize_product_evidence and fiscal_completion.py's empty-ev fallback both carry the new key through. New tests (central/tests/test_field_contract.py) cover the 5 real cases named in the mission: the beer (1 vs 19, 5% - discarded), a second beer (3 vs 4, 42.9% - MIXED/UNKNOWN), the liqueur (34 vs 22, 60.7% - still MIXED/UNKNOWN, below the 70% bar), the juice with PROD_COZINHA=1+RECEITA_INGREDIENTES (unaffected, stays OWN_PRODUCTION), and the tilapia/corvina fish (no composed evidence at all, stays RESALE) - plus a strong 90% majority case and an insufficient-sample (<5 events) case. A new end-to-end test in agent/tests/test_cfop_ippt_auto_apply.py (committed separately, see the feature/cfop-ippt-write branch) proves the weak-evidence beer never reaches select_candidates as a write candidate, independent of any write flag. Re-running the dry-run over Agent 2's real database (GTI.FDB, 527 products) after this fix: AUTO_FILL_SAFE CFOP/IPPT cells drop from 12 to 3 (the two fish CFOP fills + the juice's IPPT, all with strong, non-statistical evidence) - docs/runs/GTI_dryrun_universe_summary_after_A1.json. This corrects the Missão 3 report's 12/9(downgraded)/4(sustained) manual judgment call with a deterministic, tested engine rule. No schema/migration change. Zero Firebird writes (read-only analysis only). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
