🏗️ Change Order Evidence Reconciler

Change Order Evidence Reconciler checks invoice-line arithmetic, base-scope coverage, change-order approval state, approval and completion evidence, duplicate-looking lines, and billed totals against approved change amounts. It returns a line ledger, findings, JSON payment-review gate, and memo. It verifies supplied records only and never decides entitlement, directs payment, or provides legal advice.

What it produces

• Invoice-to-scope line ledger
• Approval and completion evidence findings
• JSON owner-payment gate
• Project-owner review memo

Use cases

• Review subcontractor extras before approving an invoice
• Catch unapproved scope and over-billed changes
• Verify approval and completion evidence survived the field handoff
• Surface duplicate-looking invoice lines

Known limitations

• The tool checks supplied records and cannot decide whether work is contractually compensable.
• Text, email, signature, and field-ticket validity remain owner and legal judgments.
• It does not create change orders, collect signatures, or direct payment.
