dimension_linear always failed with '<unknown>.AddDimLinear' on the COM
backend — pywin32's dynamic dispatch error for a method that does not
exist: the AutoCAD ActiveX API has no AddDimLinear. AddDimRotated takes
the same arguments (XLine1Point, XLine2Point, DimLineLocation,
RotationAngle), so the call site only changes the method name.
Adds a mocked regression test asserting AddDimRotated is called with
the exact point/rotation arguments and AddDimLinear never is.

Audit-driven fixes across the dual backend, the premium workflow, and the
engineering layer. 318 tests, ruff-clean.
Quality gate (the moat):
- drawing_finalize now runs the premium ISO-128 critique in addition to the
8-step validator; leftover construction, non-ISO lineweights, untrimmed
corners, duplicates and dim overlap block the gate (strict_critique fails on
warnings too).
- dim_overlap critique no longer a no-op (dim reference point + bbox fallback);
dim/construction layers resolve from the active layer set (iso13567 too).
Stability / correctness:
- view_screenshot & drawing_export_pdf render headless via Agg (no more
worker-thread SIGSEGV).
- gear tooth profile no longer self-overlaps at high tooth counts; section view
no longer duplicates bore lines; validator keyway heuristic fixed.
- ezdxf aligned/angular dim API, full-circle polar array duplicate already
covered by Sprint 1; this bundle adds save-format-from-extension,
entity_offset side selection, ARC length, properties parity (bounding_box /
rotation / char_height), mtext rotation.
COM robustness (mocked-COM tested):
- CoUninitialize on teardown; transaction commit/rollback try/finally + UNDO via
the CMDACTIVE guard; system_run_lisp guard + USERS1 value capture;
set_variable type coercion; HWND via Application.HWND; BlockInfo.description.
Security:
- HTTP remote-bind guard fires on every launch path (incl. `fastmcp run`);
StaticTokenVerifier wired into FastMCP; AutoLISP allowlist bypass-vector tests.
Hygiene: linetype-on-demand in _apply_attrs, honest view_zoom returns, snap-on-arc
sweep handling, point_tangent acos clamp, dynamic tool_groups / tool count,
word-boundary SPUR/HELICAL, undo-stack locking.
Deferred: R22 (undo/transaction stack isolation) lands with the I1 refiner (1.2),
which depends on it.
- 21 parametrized normalize_lineweight table tests (base.py, platform-independent)
- _safe_send_command: CMDACTIVE immediate/polling/timeout/variable-restore/ESC/handle-detection
- Live integration smoke test skipped on non-Windows via @pytest.mark.skipif
- Runs in CI (Linux) via mocked doc objects; no AutoCAD process required
213 tests total (29 new).
