Bloco C.1-C.4: searched every BLOB column and every XML/IMPOSTO/TRIBUT-named
table across all 5 databases - no authorized NFC-e/NF-e XML is stored
anywhere (XML_MES only holds a filesystem path on the original machine;
CARTA_CORRECAO/MDFES_XML are for correction letters and cargo manifests;
DEOLHONOIMPOSTO is the national IBPT reference table, not per-item data).
FONTE_ENCONTRADA = NFCE_ITENS's own PIS/COFINS columns (the same values used
to build the XML) - docs/PISCOFINS_TRANSMITTED_SOURCE_V1.md.
Bloco D.1-D.3: the 27 products blocked by NCM on Agent 2, categorized
(4 placeholder 00000000, 3 legacy/vencido, 5 valid-format-but-not-in-the-
active-table, 15 obvious test/garbage values) with a prioritized kb.attest
queue - real products first (Coca-Cola, chicken cuts, pâté, broths), test
cadastro last. All 27 lack a real GTIN, so none can be resolved by barcode
lookup - documented in docs/NCM_27_BLOCKED_PRODUCTS_V1.md.
dossie_contador.md (internal + anonymized) updated with the Bloco C finding.
No schema/migration change. Zero Firebird writes (read-only SQL only).
