| [`paths/`](paths/README.md) | Resolves the Harness data root and shared paths |
| [`timeout/`](timeout/README.md) | Provides deadline and timeout classification primitives |
| [`retention/`](retention/README.md) | Bounds retained text and item collections |
| [`atomic-write/`](atomic-write/README.md) | Replaces files atomically |
| [`native-command/`](native-command/README.md) | Runs host-native commands without a shell |
