The 2026 development
Trimble described agents drafting potential change orders from contracts, drawings and project records.
The governance gap
A change order is a financial and contractual instrument. The agent's draft must show which clause, drawing revision and record supports each line, and a human must own the approval.
Where CAIN-42 fits: Moat 4 — Execution Provenance & Attestation
Core question: Can we prove what actually happened? Hash-chained, signed records binding decision to execution to observable effect.
Build the change order as an evidence-backed claim: each line cites a document, a revision and a reviewer. The signed package preserves the source hashes and the approval chain.
How the wiring works
- Extract each line item and cite its source document and revision.
- Flag unsupported or conflicting citations.
- Require a human reviewer for each financial line.
- Sign the package and preserve the source hashes.
