## Module-to-WBS mapping

| Module | WBS leaves served |
|--------|-------------------|
| `modules/bms/project-management-engineering.md` | 1.1, 1.2, 1.3, 1.4, 3.1 |
| `modules/bms/head-end.md` | 2.1.x, 3.7.x |
| `modules/bms/network-infrastructure.md` | 2.2.x, 3.6.x |
| `modules/bms/controller-panel.md` | 2.3.x, 3.4.x |
| `modules/bms/field-devices-hvac.md` | 2.4.x, 3.5.1 |
| `modules/bms/field-devices-plumbing.md` | 2.5.x, 3.5.2 |
| `modules/bms/field-devices-power.md` | 2.6.x, 3.5.3 |
| `modules/bms/cabling-and-containment.md` | 2.7.x, 3.2, 3.3 |
| `modules/bms/programming-engineering.md` | 1.2 (partial), 4.x |
| `modules/bms/testing-commissioning.md` | 3.8, 5.x |
| `modules/bms/training-handover.md` | 6.x |

(Modules don't 1:1 to leaves — a module is referenced by multiple leaves, typically supply leaves + install leaves for the same physical subsystem. Programming-engineering also feeds 1.2 — engineering hours.)

**Note:** This list adds an 11th module — `cabling-and-containment.md` — to the originally proposed 10. Cabling is cross-cutting (drives quantities for all field-device modules) and warrants its own module to keep cable-cost rules DRY.

## Notes for Phase 5a

- **Build A1 (I/O list) first.** Almost every WBS leaf has a working-doc reference to A1 or one of its derivatives (A2, B1, B3).
- **Cabling-and-containment module needs to be created** when we get to 5b. It's referenced by 2.7.x, 3.2, 3.3.
- **Q-008 answer materially refines 2.7.5** (containment in-scope or shared with ME contractor). Until then, keep A-001-supplemental conservative (in-scope).
- **Q-012 answer determines** whether 4.4.3 / 7.3 / 7.4 / 7.5 are IN or EXC. Until then, keep them in 7.0.
