The Irregular engine grows each sheet from one side, so parts that fit only when the outer ones hug opposite edges never met: ten one-off brackets (four tapered 112-inch bars, four gussets, two small plates) stacked three bars on one sheet and took three 60 x 120 sheets where two hold them. After the search, a sheet-reduction pass splits a complete single-stock plan over one sheet fewer and packs each sheet edge first: large parts to the corners (flush, most outline on the edges, thinnest across the sheet), small parts into the gaps last, and one key part into the pocket between. Clamped sides move in past the keep-outs so edge parts line up on one straight edge. When no sampled orientation fits the key, ContactFit turns it by its contacts (each overlap a linear constraint on dx, dy and rotation) instead of sampling more angles; the exact no-fit free region then confirms the angle, so spacing and validation are unchanged. That job now nests on two sheets, the middle bar at 4.4 degrees; the repository benchmark jobs are unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
