A rigorous TDD development workflow enforcing Red-Green-Refactor at the pipeline level: Product Design → Technical Solution → Test Plan → Test Code → Business Code → Pre-Release Testing → System Quality Audit → Acceptance Testing. Phases 1–5 are creation phases with mandatory Ralph-loop review. Phase 6 is the pipeline's validation closure — systematic pre-release testing with bug root cause analysis and rollback paths. Phase 7 is an incremental system-level audit (16-pattern catalog, pair discovery, execution-order analysis). Phase 8 is functional acceptance — requirements traceability, AC-level verification, independent check, and release decision. No business code is written until tests exist and fail.
Design and execute double-blind A/B experiments for AI agent workflows. Progressive disclosure: assess the task below, then load the appropriate tier file (tier-1.md, tier-2.md, or tier-3.md). Each tier file is a self-contained protocol for that stakes level.
