The posts treat every non-lead feed move as a cut, so an applied blank's
display tail, or the outline of a blank posted without a plan, would have
been cut along the blank's edge. The pre-post review counted that outline
as an ordinary cutting contour.
Cincinnati, CI Fiber and the engraver now read part programs through
DisplayPerimeterTail.ForPosting: an applied program posts exactly what the
same program posts with its tail removed by hand, and an unplanned display
perimeter is refused with a message that names the part and points to Plan
Cutting. The pre-post review reports the unplanned outline by name.
The safety raise (M47 P<SafetyHeadraiseDistance>) used to fire only when
the next part had a different drawing name, which has nothing to do with
crash risk: a long rapid between copies of the same part got a plain M47,
while a short hop between neighbouring different drawings got the full
raise. Sheets are rarely flat (5/8" plate can be ~1.5" out of flat within
supplier tolerance), and longer rapids cross more of that bow.
Add SafetyHeadraiseRapidDistance (program units, default 12"): any rapid to
the next pierce longer than it takes the safety raise, regardless of
drawing. Unknown travel never does.

Part sub-program calls restored the sheet frame with G92 at the part
corner while the tool sat at the sub-program's last endpoint, shifting
every later part. The call now raises the head, rapids back to local 0,0
and restores there. Parts share a sub-program only when their posted
toolpaths match, so per-part lead-ins are kept.
Suppressed moves are left uncut: the cut resumes with a rapid past them.
Head raises go before the rapid that leaves a feature, one per rapid:
the safety raise now precedes the rapid to a new part instead of
following its first feature, and sub-program mode no longer posts M47
then M47 P2000. M47Mode.Auto posts M47 before rapids longer than
M47OverrideDistanceThreshold and /M47 otherwise. ExteriorM47 applies to
the contour spanning the part's cut extents.
The sheet GOTO targets FeatureLineNumberStart and is omitted without line
numbers. PrepareForNest pre-selects only the gas- and thickness-matching
library. Part programs are read through absolute copies, never switched
to absolute in place.
Removes the unimplemented UseSheetSubprograms, CoordModeBetweenParts and
ProcessParameterMode (G89Mode); old configs still load.

Hole sub-programs are stored incremental but were written under G90 as
if absolute, producing invalid arcs. The registry now posts absolute
copies and leaves the nest's programs untouched.
Sheet-level hole calls omitted the part location from G52, so every
part's holes were cut near the sheet origin. Calls now shift to the
part location plus the hole offset.
Hole calls were matched to sub-programs by call id, which planned
emission numbers 1, 2, ... per drawing, so holes from different drawings
shared the first drawing's sub-program and diameter. Calls are now keyed
by program reference and deduplicated by posted toolpath.
A part opening with a hole call got a synthetic rapid that posted an
empty pierce on the part edge. The rapid is now only inserted before a
contour motion with no rapid ahead of it; the hole call carries the
part comment and safety head raise that feature used to hold.
The sheet writer re-sorted parts bottom-then-left with cut-offs last.
Plate order is the cut sequence, so parts now post in plate order.
Regression tests replay the posted G-code for off-origin parts of
several drawings and check each hole's center and radius.

Group the Cincinnati and GravographIS plugin projects in a Posts/
folder so new machine posts have one home. Project names, namespaces,
and the runtime Posts/ deploy target are unchanged; only relative
paths in the solution and project references move.
