Add signed offsets, affine transforms, draft, tapered and limited extrusions, and multi-section sweeps with strict graph replay. Support closed and periodic sketch B-splines and accurate rational-surface volume integration.
Capture Builder and algebra programs into portable feature traces, emit native FTC sources, and validate geometry in isolated processes. Include the API inventory, six real trace fixtures, inferred constraint recovery, and the 50-model benchmark. All models build; the tea-cup STEP reference-kernel failure remains explicit.
pymupdf (AGPL-3.0 / commercial dual license) was on the eager package import path via inspect.drawing, so 'import simplecadapi' hard-failed without it — including inside the render worker subprocess. The drawing modules now bind a lazy proxy (real module under TYPE_CHECKING); the first attribute access performs the import and a missing pymupdf raises an ImportError naming the new 'drawing' extra. Core install drops pymupdf; the dev extra keeps it for the test suite. Verified: fresh venv without pymupdf and py-slvs passes import, build, STEP export, render, solver-backend resolution; full suite 1941 passed / 5 skipped; ty diagnostics on the drawing package unchanged vs dev.
PCG unitized-curtain-wall tower: one parametric code base, any plan (rect/chamfer/l_shape), floor count and setback policy, generating a manufacturable facade - 3,697 instances resolved onto 22-43 typed parts with a hard quantization-error bound. Pure-data layout engine (plan -> setback tiers -> per-edge subdivision -> panel schedule with K-quantized fin wave and ordered-dithered WWR), type part factories, band subassemblies, tower assembly, export (scadpkg + AP242 STEP + panel-schedule CSV) and eight verify gates with known-bad proofs. Imported as archived from the author's working stash; ported to the current SDK in the following commit. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…time SDK The example was written against the part-cache SDK removed in PR #17. Port every gate to the current API without weakening a single geometry, layout or validity check: - s2/s3: drop the P7/K8 warm-cache-hit assertions (feature gone). - s4: A2 becomes a pure determinism check (two builds carry the same definition content hash); the corrupt/dirty solve-report fields no longer exist. - s4/s5 known-bad KB10: a tampered content_hash cannot be constructed (definitions self-validate), so the case now rebuilds a DIFFERENT design and requires A2 to fire. - s7: the incremental-rebuild assertions died with the cache; the gate is now an honest full-rebuild timing report per edit step (out/incremental.json). - panels/floor docstrings and the three Chinese design notes updated for the cache removal (dated era-notes, original text kept). Also: example README (run commands, module map, known limitations), examples/README.md table row, and SDK_DEFECTS.md D11 recording the L_SHAPE reflex-corner profile vs V5 envelope conflict (open, contribution welcome) — s6's plan geometry sweep covers RECT/CHAMFER; L_SHAPE is layout-verified only. Gates: s1 3s, s2 7s, s3 80s, s4 139s, s5 279s, s6 967s, s7 264s, s8 377s - all PASS; s1-s3/s4/s5 known-bad all discriminate as designed. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…ndering The DXF -> PNG path consumes pymupdf through ezdxf's drawing backend, so the extra covers both drawing consumers, not just vector-PDF inspection. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
pcg_facade_tower example: parametric facade tower (pure-data layout engine, typed part factories, band/tower assemblies, AP242 export) with eight verify gates ported to the notebook-runtime SDK and known-bad proofs; L_SHAPE full-tower verification is an open issue (SDK_DEFECTS D11).
pymupdf becomes an optional 'drawing' extra: the engineering-drawing family (vector-PDF inspection + DXF PNG rendering via ezdxf's backend) is its only consumer; import, modeling, STEP export and VTK rendering run without it. Drawing functions without pymupdf raise an ImportError naming the extra.
Parameters are the top-level literals or scad.var of a '# ---- params ----' cell, with an optional trailing '# ui: slider(min, max, ...)' comment for the control. The editor kernel applies values an editor saved (params.json in the notebook state dir) as the defining cell finishes; headless runs take only explicit overrides. live_package/publish_live project the product from a running marimo kernel. sca ls / sca params report workspaces and notebooks from the files alone, with no change to existing examples. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…value The editor kernel runs scratch cells the notebook does not contain; the executor raised KeyError on them. params.commit_value writes a parameter's value into the cell source, keeping the rest of the line. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
The editor moves in from sca-web-editor as simplecadapi.editor (UI sources in editor-web/, built into the package; 'editor' extra). It no longer records anything itself: the kernel runs the notebook with the SDK cell executor, the server asks it for the product (runtime.live.publish_live) when marimo reports a completed run, and parameters are saved values the executor applies, so marimo's dataflow reruns what reads them. Controls come from '# ui:' comments; a workspace is any directory of notebooks. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…s inside functions code.edit stripped every line starting with 'return', including those inside @app.function bodies, and rewrote the file even when the code was unchanged. Now only the cell's own top-level return is stripped (by AST), unchanged code just runs, and @app.function cells are not edited through code mode (marimo would turn them into plain cells). Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…w look Picking in the viewport writes a selection cell (ql selectors from the picked geometry, selected_<kind>[_<i>] and selected_item) and saves a snapshot (.sca-editor/snapshot.json + viewport.png, sca snapshot) for coding agents. The viewport gets a ground grid and an axis gizmo in a CAD (Z up) frame. Cells fold to their step name, run everything above, autosave, and are deleted with a trash button; the inspector shows a JSON tree; the chrome is black and white with square 2px rules. Opening a notebook clears the model at once. ql.vertices() now resolves through solids and faces. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

Each cell header gets a copy button: the reference is the notebook path, the cell's line range in the file, its number and name; Alt/Shift+click adds the code. Line ranges come from the saved file, so they follow autosave. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…change The workspace lists the local modules notebooks import (sca ls reports them too) and opens one in a module view: autosaved source plus its dataclass fields (and commented constants) as controls written into the file. A change, from the editor or on disk, reloads the module in the kernel and reruns the notebook; used notebooks are rerun from their files. Number boxes keep the typed text until it is committed. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…the kernel The kernel runs scratch code one piece at a time, so a selection write queued behind a long run (publishing a big assembly takes seconds) delayed the cell, and fast picks piled up one thread each. The server now pushes the selection cell from memory immediately and coalesces the kernel writes. SCA_EDITOR_TRACE=1 logs the time of every kernel call. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…rnel; faster packages The cell cache is stored under a digest of the files each cell depends on (modules reached through the names it reads, through the notebook functions it calls, and through the cells it reads from; child notebooks; inputs) instead of one digest for the notebook: a changed module recomputes what reads it and restores the rest, and going back restores everything. The editor kernel runs cells through the same cache (cells downstream of saved parameter values are keyed by them; cells that run child notebooks are not cached there). The render mesh of a face is computed with numpy in the profile's fixed operation order: identical bytes, package builds about twice as fast. The editor also watches the data files a notebook lists in 'inputs'. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

While a model is being made (kernel starting, notebook opening, module reload, run all) a gray mask covers the panels: a square dot-matrix with a ripple spreading from the middle, and a small retro window with a spinner, what is going on and for how long. It shows after 250 ms, ends when the model arrives or the work fails, and does not veil interactive rebuilds. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…veil marimo interrupts the kernel when the client of /api/kernel/execute disconnects. The bridge's scratch calls had client timeouts (the 5 s watchdog ping: 10 s; the idle probe: 15 s), so any cell that ran longer than that - a use() of a child notebook - was killed with KeyboardInterrupt and the product was missing. Scratch calls now wait without a timeout and the watchdog asks /api/sessions instead. The loading veil's swell is one long wave and its dots are dimmer. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
A cell's run button is a stop button while the kernel runs it (so is run-all in the header); stopping interrupts the kernel and drops the work queued behind it. The server forwards marimo's live cell states. The editor remembers each notebook's last published package under a digest of everything the model depends on (notebook, modules, children, data, saved values, versions); switching back shows that model and the cells from the file immediately while the kernel boots, and the kernel's own publish only reloads the view if the model differs. Revisiting an assembly went from 16.5 s to 0.3 s. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
scene.preview makes what a viewer under edit needs, without a package: the triangles, edge segments and vertices of each part, the index range of every face and edge (so they can be highlighted and picked), each part once with its instances' placements, and entity_info for one picked entity (worked out on demand; the same properties the package sidecar holds). Geometry is kept per (BREP content, tolerance), so a part that did not change previews for free even if its object was rebuilt. Entity ids and properties match the package's. Solids no longer build a mesh when created: nothing read it while modeling, and every intermediate solid paid about 20% of the run for one. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…uilding a package The kernel publishes a SCAPREV1 preview (triangles, edges, vertices, face/edge groups) straight from the solids; the viewer loads it, and per-entity details are fetched on demand (entity.info) before a selection cell is written. Previews are cached per dependency signature for instant revisit. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…ine dependencies
marimo asks whether to sandbox such a notebook and waited on stdin forever
("marimo not ready after 60s"). Pass --no-sandbox and close stdin.

Edges and faces are tessellated separately, so a mesh chord can bulge past an edge's polyline and break it into dashes. The edge shader now moves its depth 0.4 mm towards the camera (screen position unchanged). Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…switching - bottom dock: log of events/errors, progress of the cells being re-evaluated, running/queued/blocked on cells; errors leave the header - opening notebooks is ordered (latest wins), a superseded open ends quietly, the list highlights the notebook being opened immediately - boot waits for the instantiate run before publishing; a failing setup is reported as the cause; refreshed pages load an unchanged model; viewport redraws after resize Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

CI syncs only the dev group; three drawing tests import pymupdf, which became an optional extra, so collection failed. Putting it in the group keeps local uv sync --group dev able to run the whole suite. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
The editor's packages join the dev group so the main job no longer skips test_editor.py, and a separate job runs it with SCA_EDITOR_E2E=1 to boot a real marimo kernel. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
feat: code-first editor (sca edit) and the agent landing path
…es Re-Studio - both READMEs open with the line to paste to a coding agent - pillar 3 is now the code-first editor (screenshot added); Re-Studio and the standalone sca-web-editor references are gone - update notes for 2.2, install and examples sections brought up to date - remove the Re-Studio skill workflow and its demo media (10 MB) Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
