XCLIP clips block and xref references to a rectangular, polygonal or
closed-polyline boundary (Invert clip, ON/OFF, Delete, generate Polyline;
Clipdepth is ignored in 2D). The boundary is Insert::clip, in block
coordinates, so it follows its reference; other references stay whole.
Clipped references are drawn, plotted and framed (XCLIPFRAME 0/1/2) cut
to the boundary, attributes included, and their extents are cut to it.
DXF and DWG read and write it as the reference's ACAD_FILTER/SPATIAL
SPATIAL_FILTER; filters the model can't hold stay foreign data. Gap F2.

AUDIT checks for missing layers, linetypes, styles and block definitions,
current-style variables naming missing entries, invalid geometry (NaN or
infinite numbers, zero-length lines, zero-radius circles and arcs),
block definitions that contain themselves, duplicate handles, and
references to missing objects (dimension associations, groups,
constraints, viewport layer lists). It asks "Fix any errors detected?
[Yes/No] <N>:"; the JSON form `audit {fix?}` returns a structured
report. RECOVER opens a file through the read hook and applies AUDIT's
fixes. A question prompt now shows its answers without "or".
