**Source:** Project intake (CONTEXT.md) + Technical Lead breakdown (BREAKDOWN.md)
**Author:** Manager 🎯

**Created:**
- `components/sandwich-beam.md` — initial component file from intake data
- `materials/steel-aisi.md` — material placeholder
- `fea/models/sol101-static.md` — FEA model placeholder from breakdown
- `dev/gen-001.md` — generation document

**Key findings from breakdown:**
- Baseline FAILS displacement constraint (22 mm vs 10 mm limit)
- Feasible region may be narrow — stiffness and mass compete
- Sandwich effect (core thickness) is the primary stiffness lever
- 9 gaps identified requiring CEO input before proceeding
