Implement Plan

Purpose and authority

Implement the exact approved plan as the smallest complete patch. The plan limits behavior changes; repository evidence determines local form; the v3 implementation contract proves the result.

Accept finalized plan-contract v6 plans with either the legacy request binding or the enriched typed-handoff kind, version, and selected-item binding. Reject ambiguous, unfinalized, unsupported, receipt-mismatched, or materially contradicted plans. Route semantic gaps to plan-change; never reinterpret product intent during implementation. Preserve unrelated dirty work byte for byte, never edit a dirty target without explicit authorization, and stop on a concurrent target change.
