| 3 | Coverage tiers |
| 4 | -------------- |
| 5 | Unit — parser flags, dead-code removal, docstring schema. |
| 6 | Integration — switch, create, already_on, detach, --dry-run, conflict resolution. |
| 7 | End-to-end — full CLI invocations: text and JSON output, all operations. |
| 8 | Security — ANSI injection in target, error routing to stderr. |
| 9 | Stress — checkout under high file counts, concurrent checkouts. |
