+# CutNesting 2D reference result - dataset v1.1.0
+
+This is the first public reference-machine run of the CutNesting production 2D
+nesting engine. It measures a named engine commit against an immutable public
+dataset; it is not a comparison with another tool.
+
+## Reproducibility record
+
+- Generated: 2026-07-22T08:19:02.698Z
+- Dataset: `v1.1.0` at commit `403f9c4eaea7757d2ba6106e917d4d7657675c72`
+- Suite and methodology: `1.0.0`
+- Engine: `nesting-2d-wasm` `0.1.0`, commit `b974023d6c66aa19959dd8d9f2dc1e88fb56cefb`
+- Production entry point: `optimize_nest`
+- Execution target: native Rust, not browser WebAssembly
+- Timing: 3 warmups and 30 measured synchronous solver calls per case
+- Reference machine: Intel Core i5-9400F, 6 logical cores, Windows x64
+- Toolchain: Rust/Cargo 1.96.1 and Node.js 26.4.0
+- Source and dataset worktrees: clean
+
+The complete JSON retains every raw timing sample, production layout,
+validation outcome, input hash and machine field. The CSV is a compact,
+analysis-friendly view of the same per-case metrics.

+## Results
+
+| Case                          | Placed | Unplaced | Geometric utilization | Estimated unused area | p50 solve time |
+| ----------------------------- | -----: | -------: | --------------------: | --------------------: | -------------: |
+| Exact square grid             |      4 |        0 |              100.000% |                0.000% |       0.565 ms |
+| Steel plate panel grid        |     12 |        0 |               93.440% |                6.560% |       7.944 ms |
+| Wood sheet panel grid         |     12 |        0 |               96.748% |                3.252% |       7.652 ms |
+| Irregular remnant with a void |      4 |        0 |               25.397% |               74.603% |       7.863 ms |
+| Finite sheet stock exhausted  |      1 |        2 |               36.000% |               64.000% |       0.516 ms |
+
+The irregular-remnant case is a geometry and feasibility fixture, not a low-
+waste claim. The finite-stock case intentionally leaves two parts unplaced and
+tests explicit stock-exhaustion reporting.
+
+Geometric unused area is sheet polygon area minus placed part polygon area.
+It is not disposable manufacturing waste: this benchmark does not model kerf,
+lead-ins, pierces, common-line cutting, or generated toolpaths. Part gaps and
+edge margins constrain placement but remain included in unused area.
