PCBA BOM cost-optimization (target COGS, alt-vendor selection)

pcb_layoutpack: pcba-cost-opttier 2blind

Present a seeded BOM containing premium/out-of-stock primary parts and a component catalog with cheaper in-stock equivalents. Grade the agent on: summing the baseline unit cost, selecting the cheapest compliant in-stock alternative for each line item, computing the optimized COGS, and reporting whether the target COGS is met and out-of-stock parts avoided. All gold is public-param-derived via makerbench.bom_cost; no oracle needed.

Grading ladder

1
Structural
Compiles to a single, watertight, non-empty solid.
2
Geometric
Outer dimensions / bounding box match the brief within tolerance.
3
Physical constraints
Mass, fit, and physical-constraint targets are met.
4
DFM
Manufacturable for the process (e.g. minimum wall thickness).
