Issuance spine
Job order → engineer assignment → site evidence → certificate draft → role-gated approval → branded PDF. The chain a real certification company already runs.
Outcome
Every issued PDF is the last mile of a controlled record — not a Word file that escaped the office.
- Job created, assigned, and accepted with a named engineer
- Site checklist, photos, and dual signatures captured once
- Drafts cannot skip approval or appear on the public registry
