+## Provider evaluation (2026-09-26)
+- **DotCompany — NOT integrated.** The free query (25/day per IP, no signup) is the *website* demo for human use; the API (`/api/v1/catalogo/gtin/{ean}`) is prepaid credits (4 credits = R$ 0,04 per query, packages from R$ 120); the only free API access is a `dc_test_` sandbox with test data. Automated free use is not offered, so no adapter (would violate zero cost / permitted automation).
+- **OSCBR / RSC Sistemas — adapter implemented, optional.** Free initial plan without card, 20 req/min, token via account registration (Basic auth on `/oauth/token`, 1 h Bearer), `GET /api/gtin/infor/{gtin}` (fields `ncm`, `nome`, `marca`, `categoria`, `pais`). Terms are shown only inside the authenticated panel, so the operator must create the account and read them; the Hub never creates accounts. Without credentials it is `NOT_CONFIGURED` and makes no request.
+- Cosmos stays optional (`COSMOS_TOKEN`). Nothing else qualified (GS1 CNP is a paid membership; Verified by GS1 is not an automation API).
+- `PAID_PROVIDER_CALLS=0`; `ALLOW_PAID_PROVIDERS=false`.
+
+## Field audit (`docs/PRODUCT_ENRICHMENT_FIELD_AUDIT_V1.json`)
+24 fields checked against `field_contract`; only `CLASSIFICACAO_FISCAL`, `CEST`, `IPI` have a deterministic, company-independent rule. All others need company/operator context (product role, ICMS treatment, origin, PIS/COFINS profile, entry scope, rounding) or description evidence (EX_TIPI) and are excluded on purpose; `CST_IPI` is NOT_APPLICABLE for non-IPI companies; `CCLASSTRIB` stays with the RTC gates.
+
+## Re-baseline after inactivity (1.3.1)
+While the function is DISABLED / WAITING_FEATURE_CONFIGURATION the Agent marks a re-baseline; on reactivation the current catalogue becomes history, so a long-disabled installation never sends a burst of products to the providers.
+
+## Production KB seed strategy
+Production KB starts empty (0 products, head 0028 before deploy). The lab databases are **not** imported into production: their observations are `CLIENT_OBSERVATION` evidence only and cannot verify anything alone (93/241 shared GTINs disagree on NCM). The KB grows from provider evidence on real new products; `scripts/enrichment_lab_kb.py --seed-url` exists for a dev/staging seed only.
