nesting-orientation-review-gate

What problem does it solve?

Gate orientation-preference changes in the nesting heuristic to prevent loss of fit behavior and determinism.

Core Features & Use Cases

• Separate the preference case from the necessity case to preserve deterministic results.
• Prove the rule on the real service path by asserting actual placement geometry and Rotated90.
• Add a preserved-rotation counterexample to show old rotate-to-fit behavior remains valid after changes.
• Re-run the same request twice and compare placement order, coordinates, dimensions, and rotation flags to ensure determinism.
• Keep one no-fit regression check to guard against misleading reason codes.
• Prefer a narrow priority key over a heuristic rewrite to maintain deterministic ordering.

Quick Start

Generate a regression test plan to validate orientation-preference changes in the nesting heuristic while preserving fit and determinism.
