plan-run

Execute a plan produced by /plan-init + /plan-phase — the current planning suite. Reads plan.md + the execution.md checkbox tracker + the current phase doc (never phases.md), and runs phases in order, resuming from the first unticked box and re-reading that phase document before executing it. Runs the per-phase gate (scoped tests + web-verify for UI + a single-pass cyw author review + diff-review, by a different model when one is available, on any diff with reviewable code), fills each phase's evidence record, makes at most one commit of its own work per phase, and assembles an as-built.md drift report. Refuses a plan that carries no Format: v2 marker. Use when the user invokes /plan-run, or says "execute the plan", "run the plan", "continue the plan".
