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, cross-runtime when a second runtime 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".
