Examples index

• examples/ — small single-part .coscad files (shapes, booleans, transforms, bezier, zoo of all primitives, and loft — numeric bindings plus lofted funnel and lug).
• examples/topological/ — pipeline syntax and anchor-relative modelling: pipeline_basics, topo_tour (annotated), tbracket (the zero-translation seam bracket, verified identical to its coordinate-built twin).
• examples/assemble/ — .assemble specs: corner/frame (recursion; rail200/rail120 are plain-bar stand-ins for the 2020 extrusions, referenced ×0), spill (multi-bed: the design stage reports plate overflow, coscad next spills to more beds), autotest (orientation search), and bow3/ — the flagship three-part manufactured assembly.
• examples/assemble/tesseract/ — a 100 mm nested-cube display with 12 mm split hubs and captured printed joints, no screws or nuts. The supported build, finished object, three-piece fit test and retained bolted version are described in Tesseract.
• examples-next/ — earlier manufacturing-era parts (bow2 generation, greaser tool with its manifest kept as a reference output), and example_check.assemble with parts a/b/c — a coscad check demo whose lid sits 0.2 mm above the blocks, under the declared 0.3 mm clearance.
• examples/archive/ — a few historical scratch files (the old debug* and test_* files were removed in the repo-hygiene change).
• examples/haskell/ — embedded-DSL samples for ghci (cabal repl, then :load examples/haskell/ExampleGear.hs). They are not library code, but the haskell-examples` test-suite compiles them and renders one shape from each, so they cannot silently rot.

Generated output is gitignored and not committed: .scad/.stl, manifests, _design.json, plan _plan.json/_plan.md and _step* scenes and images. Regenerate with coscad <file>, coscad next <file> or coscad plan [--png] <file>. Exceptions that stay committed: the print records under models/ (each next manifest, the _next_ part scenes and print-run.json/validation.json), the tesseract adhesion-retry verification.json, and the greaser reference manifest. Every example (outside archive/) is compiled, rendered, and compared against test/golden/ by cabal test; see README "Tests".
