# Gen 001 — Project Intake + Technical Breakdown

**Date:** 2026-02-09
**Sources:** CEO intake in #project-hydrotech-beam, Technical Lead analysis
**Author:** Manager 🎯

---

## What Happened

1. Antoine submitted the Hydrotech beam optimization request via #project-hydrotech-beam
2. Manager created project folder and CONTEXT.md from intake data
3. Technical Lead produced a full technical breakdown (BREAKDOWN.md)
4. Manager and CEO agreed on project structure (KB-integrated layout)

## Key Findings

### From Intake
- Sandwich I-beam, steel, with lightening holes in web
- 4 design variables (3 continuous + 1 integer)
- Current design: ~974 kg, ~22 mm tip displacement
- Targets: minimize mass, displacement ≤ 10 mm, stress ≤ 130 MPa

### From Technical Breakdown
- **Critical:** Baseline already violates displacement constraint (22 mm vs 10 mm)
- Single-objective formulation recommended (minimize mass, constrain the rest)
- Two-phase approach: DoE (40–50 trials) then TPE (60–100 trials)
- Significant variable interactions expected (sandwich theory, hole interactions)
- 9 gaps identified needing CEO input
- Overall risk: MEDIUM-HIGH (feasible region may be tight or empty)

## KB Entries Created

- `components/sandwich-beam.md` — component file with specs, behavior, interactions
- `materials/steel-aisi.md` — placeholder, needs NX model data
- `fea/models/sol101-static.md` — solver setup, pending gap resolution

## Decisions Made

- DEC-HB-004: KB-integrated project structure (Approved)
- DEC-HB-005: No Notion, Gitea + .md only (Approved)
- DEC-HB-006: KB skill extension pattern, no fork (Approved)

## Open Items

9 gaps pending CEO input (see [_index.md](../_index.md)):
- G1–G2: Geometry and loading (most critical)
- G3–G4: Result extraction specifics
- G5: Geometric feasibility at extremes
- G6–G8: NX model details
- G9: Stress allowable basis

## Next Steps

1. Resolve gaps G1–G9 with Antoine
2. Upload reference models to `models/`
3. Begin NX model introspection
4. Set up first study (DoE)
