  1. Stream Ingestion: Zero-copy memory mapping of input statement bytes.
  2. Layout Tokenization: Spatial bounding-box and tabular coordinate mapping.
  3. Field Normalization: Canonical standardization of transaction codes, currencies, and dates.
  4. Schema Validation: Mathematical checksum balance verification.
