In plain terms: L1 takes raw material (PDFs, CAD metadata, spreadsheets, prior files) and turns it into clean, structured objects, while always keeping a link back to exactly where each piece came from.

​
What it does

L1 normalizes source material while preserving . It parses rules, documents, CAD metadata, tables, bills of material, PDFs, and prior vessel records into typed objects the rest of the system can reason over. The discipline here is “never lose the source.” Every normalized object can trace back to the exact document, page, and version it came from:
  • PDFs become extracted requirements with page references.
  • CAD metadata becomes typed objects.
  • Bills of material become line items linked to materials.

​
What L1 outputs

  • normalized_document
  • extracted_requirement
  • cad_metadata_object
  • bom_line_item
  • evidence_object

​
Why provenance matters here

If a normalized object cannot point back to its origin, then any later claim built on it is unverifiable. By preserving the trail at ingestion time, L1 makes it possible for a clearance value or a rule citation to be traced all the way back to the original document, which is what makes a decision defensible later.
