fix(pockets): skip pocketing in high-density zones (eta > eta_solid)
...
High density (η > 0.7) means high stress → leave solid, no pocket.
Only low-density regions get lightweighted.
Scenario comparison with s_min=30, s_max=70:
- Baseline uniform (w=0.5): 78 pockets, 2886g
- Bottom-right heavy: 41 pockets, 3516g (bottom stays solid)
- Left-side mount: 27 pockets, 3799g (left stays solid)
- Center pressure: 15 pockets, 4295g (center stays solid)

refactor(triangulation): hex grid isogrid layout replaces constrained Delaunay
...
Complete rewrite of triangulation engine:
- Regular hexagonal-packed vertex grid (equilateral triangles)
- Density-adaptive refinement: denser near holes, coarser in open areas
- Boundary-conforming vertices along frame edge and hole keepouts
- Delaunay on point set + clip to valid region (inside frame, outside keepouts)
- Result: proper isogrid layout, 87 pockets from 234 triangles
- 553 NX entities, min fillet 4.89mm, mass 2770g
- No more dependency on Shewchuk Triangle library (scipy.spatial.Delaunay)

tune(brain): uniform triangulation + bigger spacing for r_f=6mm fillets
...
- Switched to uniform triangulation (no density-adaptive refinement for
initial pass — saves that for stress-informed iterations)
- s_min=45mm, s_max=55mm (was 12/35) — larger triangles fit 6mm fillets
- Boss keepout circles: 12 segments (was 32) — less boundary clutter
- Fillet must be >= 80% of r_f at every corner or pocket is skipped
- Result: 75 pockets, 481 NX entities, min fillet 4.85mm, mass 4066g
- adaptive_density=True param enables density refinement for future stress iterations

fix(brain): enforce r_f=6mm minimum, reject pockets that can't fit fillets
...
- Default r_f raised from 1.5mm to 6mm (machining constraint)
- Default min_pocket_radius raised to 6mm
- Pockets that can't fit r_f at any corner (within 80% tolerance) are
skipped entirely — left solid for more stiffness in tight areas
- Result: 26 pockets (was 432), 187 NX entities (was 13,061)
- Min fillet radius: 4.88mm, all >= 4.8mm (80% of 6mm)
- Mass: 4,601g (was 3,480g — more solid = heavier but manufacturable)

refactor(brain): structured pocket output — 3 lines + 3 arcs per pocket
...
Replaced Shapely buffer-based fillet (59-pt polylines) with exact geometric
fillet computation. Each pocket now outputs:
- 3 straight edges (line start/end pairs)
- 3 fillet arcs (center, radius, tangent points, angles)
NX import updated to use SketchLineBuilder + SketchArcBuilder (3-point).
Total NX entities: ~2,600 (was ~13,000). Includes arc fallback to 2-line
segments if SketchArcBuilder fails.
Also outputs circular hole definitions for future NX circle creation.

fix(import): use SketchLineBuilder instead of model curves + AddGeometry
...
Model curves (part.Curves.CreateLine) are SmartObjects that can't be added
to a sketch via AddGeometry. Switch to SketchLineBuilder which creates
native sketch geometry directly (SetStartPoint/SetEndPoint/Commit).
