Detect OpenSCAD, probe real PNG rendering, and report dependency versions and limits.

Create and validate version 1; invalid geometry remains saved and editable.

List projects with UTC timestamps and latest status.

Read metadata, current code, exports, and the latest finalization report.

Read the checksum-verified current SCAD snapshot.

Atomically update code if expected_version matches, invalidating previous results.

Compile to a temporary STL and inspect for empty geometry, recording diagnostics.

Render a verified PNG for a named view or a numeric 6/7-value custom camera.

Render six default views, or 1–12 requested named views, in parallel preserving order.

Export STL, 3MF, OFF, AMF, DXF or SVG with fixed CLI arguments.

Inspect a current verified STL/3MF export or create a temporary STL automatically.

Compare X/Y/Z in project units; null skips an axis, tolerances use the larger bound.

Check mesh and build extents; wall thickness, supports and clearance stay unknown.

Validate, render, export and inspect one revision; finalize only if all gates pass.

List immutable versions, UTC timestamps, summaries and SHA-256 checksums.

Restore a historical snapshot as a new version, retaining the complete history.

Move a project to trash only when the confirmation ID matches exactly.
