Slice 3 of common-line cutting. On costly plate (N26-295: 3/16 RA310S at about $2,500 a sheet) pairing parts one kerf apart fits the part the spacing cannot: the last plate's 38 parts fit on one 48x120 with Auto Nest only with pairs. - Drawing Properties gains "Allow common line" (Drawing.AllowCommonLine, off by default because customer edge-quality needs vary). The nest's CommonLineUsage (Off / When it adds parts / Whenever available) is set in Auto Nest and seeded from Tools > Nest Defaults; both persist (nest.json, defaults.json). - NestPipeline runs the ordinary solve, then, with a level on, trials where eligible parts are offered as kerf-gap pair compounds. Placed pairs expand into parts plus explicit NestJobCommonLine groups, are validated again, and CommonLineRanking keeps a trial only by the level: count first, then sheets; "when it adds parts" keeps the plain layout on a tie, "whenever" also takes a shorter cut or less material, never at the cost of a part. Engines, FillScore and their comparers are unchanged; Off asks the engine exactly what it did. - NestLayoutCheck exempts members only through a sheet's explicit group list and only when the job allows common lines; materializing and committing create Plate.CommonLines. - Server nesting writes common-line jobs as version 3 and replays the recorded trial answers, so the desktop binds the same groups. - Fill Area honors the level through a PlateFillService overload. - The benchmark gains --common-lines <level> --kerf <k>. Benchmark (synthetic nests + N26-295, --parallel 1): with no flag and with --common-lines off every engine matches the base commit; with a level on no layout becomes invalid and three runs save a sheet at equal nested area.
