/gsd-execute-phase

/gsd-execute-phase N — Phase 3. “Execute all plans in a phase with wave-based parallelization.” Discovers task dependencies, groups them into parallel execution waves (see pattern-wave-parallelism), spawns a gsd-executor subagent per task in a wave — each in a clean ~200k-token context (pattern-fresh-context-subagents) — and collects results. gsd-verifier runs a goal-backward analysis afterward.

Produces: artifact-atomic-commit — one atomic git commit per completed task (gsd-executor is the only agent with Edit tool access).

Flags: --wave N (execute only Wave N; staged rollout), --interactive (sequential inline execution with user checkpoints).
