- Add verify_phase_goal step to execute-phase workflow
- Verifier outputs structured gaps: YAML for planner consumption
- Add --gaps flag to plan-phase for gap closure mode
- Route by verification status: passed, gaps_found, human_needed
- Gap closure creates sequential plans (04, 05...) from verification gaps
- User stays in control at each decision point

- gsd-verifier.md: dedicated verification subagent with all logic baked in
- Goal-backward verification: checks codebase, not SUMMARY claims
- Creates VERIFICATION.md, returns status to orchestrator
- execute-phase spawns gsd-verifier instead of general-purpose

Moves all plan execution logic into a dedicated subagent:
- Deviation rules, checkpoint protocols, commit formatting
- Summary creation, state updates, TDD execution
- Authentication gate handling, continuation support
Installer now copies agents/ to ~/.claude/agents/
