🛡️ Phase 4 Playbook — Quality & Hardening
Duration: 3-7 days | Agents: 8 | Gate Keeper: Reality Checker (sole authority)
Objective
The final quality gauntlet. The Reality Checker defaults to "NEEDS WORK" — you must prove production readiness with overwhelming evidence. This phase exists because first implementations typically need 2-3 revision cycles, and that's healthy.
Pre-Conditions
- Phase 3 Quality Gate passed (all tasks QA'd)
- Phase 3 Handoff Package received
- All features implemented and individually verified
Critical Mindset
The Reality Checker's default verdict is NEEDS WORK.
This is not pessimism — it's realism. Production readiness requires:
- Complete user journeys working end-to-end
- Cross-device consistency (desktop, tablet, mobile)
- Performance under load (not just happy path)
- Security validation (not just "we added auth")
- Specification compliance (every requirement, not most)
A B/B+ rating on first pass is normal and expected.
