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
