V-model execute: CP-2 plan → CP-3 build → CP-3v component verify → CP-4 integration verify (full) → CP-5 acceptance. Worker never grades its own homework; evidence rows trace back to AC-n. Use via /execute.

Prompt

We are running a single-task feature update categorized under the normal lane. Should we spawn the integration verifier for Phase 5 (CP-4)?

Closed-loop execute (V-model right arm)

Mechanical verification pipeline. Every verify step emits evidence rows tied to acceptance criterion IDs (AC-n).

When to use

/execute <task> or /execute <spec-path>
Any skill at normal+ lane after implementation
Code changes, deploys, multi-step vault deliverables

Phase 0 — Lane + run folder

bash .claude/lib/lane-classify.sh explain "<task>"
bash .claude/lib/checkpoint.sh init 04-projects/harness/runs/<YYYY-MM-DD-HHmm>

Lane	Checkpoints
`tiny`	CP-3 → CP-5 (if mutating)
`normal`	CP-1 → CP-2 → CP-3 → CP-3v → CP-5
`full`	+ CP-4 + claim-verifier + CP-6
`bug`	root-cause ledger (CP-0) before CP-3

Record: checkpoint.sh record <run-dir> CP-0 PASS|SKIP "<lane>"

Phase 1 — CP-1 Spec (acceptance criteria)

If spec exists, use its ## Acceptance criteria + traceability matrix. Else write:

04-projects/harness/runs/<id>/criteria.md using 04-projects/harness/templates/SPEC-template.md (criteria + matrix only).

Each criterion: falsifiable + AC-n ID + verify method.

Record: checkpoint.sh record <run-dir> CP-1 PASS "N criteria"

Phase 2 — CP-2 Plan

Map tasks → AC IDs in evidence/CP-2-plan.md. Update matrix status to pending.
