Bank Certificate Envelope

Type bank_certificate runs on the universal Qwen vision pipeline with Reducto disabled — single-page issuer-signed letters certifying an account. The envelope is nested under processed_data.bank_certificate_data:

Validators that fire on every cert (results in validation_flags[]):

  • field_presence — five core fields must be extracted (date issued, bank name, holder name, account number, balance).
  • period_consistency — ADB window length within [30, 400] days; date opened before date issued; balance-as-of within 30 days of date issued.
  • positive — account balance must be > 0.
  • field_cross_check — Gemini 2.5 Flash re-reads account number, balance, ADB, and date issued from the page image and flags mismatches with Stage 1 Qwen.

Cross-document verification: when a bank_certificate shares a doc set with a payslip, bank_statement, passbook, government_id, or certificate_of_employment, the API emits cross_doc_flags[] on BOTH documents indicating whether the account holder name matches. Account-number match against bank_statement / passbook also runs when bank names align.
