plan-run

Orchestrator-driven execution of an approved implementation plan — slices the work, delegates each slice to implementer subagents, verifies against intent, and runs adversarial review rounds. Execution loop: 1. Green gate — tests, lint, and typecheck pass before review 2. Slice → delegate → verify — each slice checked against the plan's acceptance criteria 3. Adversarial review — up to 3 rounds fixing real blockers 4. Re-verify after each fix round Consumes plan-architect output directly. File-collision guard prevents parallel slices from conflicting.
