Implement

Flow

Analysis → Gate pre-run → TDD(RED→GREEN→REFACTOR) → /verify → /review → /wrap

Execution

1. Analysis: Review plan, identify affected modules

2. Gate pre-run (MUST — before coding) Run the PLAN's [unverified-gate: probe=…] / Phase 0 probes before RED. Fail → halt + report (don't build on a falsified assumption). Map Acceptance/DoD → RED tests; mark unverifiable as [unverified-gate] to carry to verify/wrap. Detail → references/gates.md (tag vocab: ../clarify/references/provenance.md).

   Rust-specific probes:

   • cargo check — whether it compiles
   • cargo test -- --list — verify test targets exist
   • make check — unified fmt + clippy + test gate

3. TDD Cycle:

   • RED: Write failing test first
   • GREEN: Minimal code to pass
   • REFACTOR: Clean up (keep tests passing)

4. Auto-call /verify: On implementation complete

5. Auto-call /review: On verify pass

6. Auto-call /wrap: On review PASS

Commands

cargo test
cargo clippy -- -D warnings
cargo fmt --check

Rules

• No implementation without test
• On verify fail → fix and retry
• On review FAIL → fix and retry
• Complete full chain without stopping
