Manufacturing Evidence Adapters

Manufacturing evidence adapters turn generated fabrication files into proof-pack evidence. The first adapter scans an output directory and records:

  • Gerber files;
  • Excellon drill files;
  • BOM CSV;
  • pick-and-place CSV;
  • manufacturing manifest JSON;
  • ZIP bundles;
  • optional ODB++ and IPC-2581 attachments when present.

Each artifact record includes a relative path, kind, file size, and SHA-256 hash. Gerber and Excellon files receive smoke validation so CI can fail early when an exporter emits malformed or incomplete files.

Fab profile validation is represented as release-blocking manufacturing evidence: DFM errors block release, warnings remain visible for review.

Current limitations:

  • Gerber/Excellon smoke validation checks basic syntax markers only.
  • ODB++ and IPC-2581 records can be attached to proof packs, but full external parsers are intentionally left to provider-specific adapters.
  • Evidence is not manufacturer approval and does not remove human fabrication review.
