EVIDENCE
Your team approves before anything ships.
Every variation points at its source. Every variation links back to the scope, drawing, client decision, or site change that triggered it.
Every change is reviewable. Your contracts lead reviews the draft before it becomes part of the record.
Every decision leaves a trail. Approvals, edits, sign-offs, and source references are timestamped and traceable.
