Reverse-engineered bracket

reverse_engineeringpack: reverse-engineeringtier 2blindperception

Reconstruct a clean parametric solid from non-answer-bearing observed evidence (noisy measurements + declared symmetry), graded deterministically on observed-bbox fit, recovered hole/symmetry, and manufacturable reconstruction. Promoted from the reverse-engineering scaffold-alpha (#4/#5).

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).
