Part.CloneAtOffset hands the copy the source's Program instance. The copy
cloned before rotating, but the source still owned the program, so rotating
the source turned the program under every tiled copy while their location
and bounds stayed put.
Program now carries a sticky SharedByParts flag that CloneAtOffset sets, and
a part copies its program before rotating when it does not own it or the
program is shared. The flag lives on the program rather than the part so a
restored cutting state, which reinstates ownership field for field, cannot
re-alias a shared program. Unrotated copies keep sharing one instance, which
the fill and overlap caches key on.
Update, ApplyLeadIns and ApplySingleLeadIn install a fresh program and now
own it, saving a needless copy on the next rotate.

On an enclosed machine a cutout slug that tips once cut free can stand up
above the sheet and catch the enclosure door when the pallet changes. The
head already keeps off cut cutouts, so this is about clearing the door, not
the head.
Cutting Settings > Cutouts > "Slice slugs the support grid can't hold
level" (CuttingParameters.SliceTippingSlugs, off by default, saved per
machine thickness and written only when on) makes Plan Cutting cut each
such slug along the bed's contact lines (grid rows and columns, slat center
lines) before the cutout, so no piece keeps a contact and the pieces drop
between the supports. Each slice stops a kerf short of the cutout, so the
pieces stay attached until the cutout's own kerf frees them together. A
slug the bed holds level, or one on no contact, is left whole; a cutout
holding another part or another of its part's cuts is never sliced.
Slices are break cuts emitted right after the drawing's own break cuts,
pierced on themselves and led straight back to their start. The
released-contour proof now leaves out straight break cuts lying wholly
inside one of the part's closed holes, since the grid cells they free are
scrap; break cuts in material still take part. The plan fingerprint only
changes when the setting is on.

Master added head-raise markers, common-line shared cuts and remainders to
the CI Fiber's own contour extractor, which this branch replaced with Core's
shared PostContours. Those now live in the shared model: PostContour carries
Raised, IsCommonLine and RemainderWinding, and Classify gives remainders the
perimeter macro on their perimeter's side and shared cuts no kerf side.
ContourWinding uses PortableMath for trig, as master's Core guard requires.

The CL post wrote the configured default side (G41) on every contour,
so a contour wound against OpenNest's convention was compensated into
the part. It now takes each feature's side from Core's shared
PostContours winding rule, as the CI Fiber post does: the perimeter is
picked across the part's cut features and hole sub-program contours
are always holes. Correctly wound drawings post unchanged.
Remove the "Default kerf side" post setting; saved configs that still
carry it load as before. Expose PostContours.Flatten and Classify so a
post can classify one part's features itself.
Add CL tests for a square with a hole: the exact inline program, cuts
that match the shared contours on the sheet, G41/G42 keeping the part
out of the kerf inline and through part sub-programs, and identical
output from absolute and incremental part and hole programs. The
replay now records the compensation in force on each cut.

Move the CI Fiber post's contour extraction and winding into Core as
OpenNest.CNC.Posting.PostContours and ContourWinding, so every post can
take sheet- or part-frame contours with the perimeter and kerf side
already chosen instead of re-deriving them. CI Fiber now writes from
the shared model; its golden output is unchanged.
Scribe marks are never picked as the perimeter and get no kerf. A cut
that resumes after suppressed moves starts a new contour where they
end, so it is no longer cut as a chord across the gap.
Add tests for a square with a hole in sheet coordinates, identical
contours from absolute and incremental part/hole programs, rotation,
and the kerf side for both windings.

Geometry, nesting and import code now call PortableMath instead of
System.Math for Sin, Cos, Tan, Atan, Atan2, Asin and Acos (Core, Engine,
IO, Data; 269 calls in 64 files). A test fails if those projects call the
runtime's trig again.
With the runtime's trig, Windows and Linux disagreed in the last bit at
non-quarter angles and the same job could nest differently: the
learned-angle nests (a cross fixture) placed 23 parts in Strip on Windows
and 28 on Linux. Now every Engine.Tests pin gives the same layout on both
(3600 passing on Linux and on DesktopPC), Linux layouts are unchanged, and
the learned-angle rows are re-pinned to the shared layouts, which pass the
overlap and work-area checks, and run on every platform again.
Fixes Project Memory 518f3b58.
The part cut first no longer makes a separate uncompensated centerline
cut with its own lead-in and lead-out, then re-pierces for its
remainder. It cuts its outside compensated, which puts its shared edge
on the kerf centerline, starting on the common line: a straight lead-in
from the scrap along the shared edge, then the line and on round its
perimeter with no lead-out. A member with spans already cut stops in
that kerf and cuts its last stretch from it, ending beside the part it
is cut before. Partners still cut only their remainders.
Replay's tabbed-ring accounting now accepts pieces that tile each span
exactly once, and the pre-post review counts a span as cut by a
member's compensated edge (or an older centerline cut).

Straight spans of one pair that meet at a corner chain into one shared
path (CommonLineGeometry.Paths). Plan Cutting cuts it as one open
centerline cut through its corners, pierced and left in scrap along its
end legs; each member's spans run on to its own vertex at a corner, so
the path is one tab run. Join Common Line slides along the main edge so
the step of a Z or L also lands one kerf apart, and the plate draws the
path through its corners.

N26-295's PT42 pairs saved spacing in slice 1 but every shared edge was
still cut twice, costing a pass per edge and risking a freed part
tipping under the head on the second pass.
Plan Cutting now cuts a plate's common lines once unless the plate is set
to cut them twice. Each group is cut member by member, owner before
partner (a captured dependency that search and replay enforce, so a kept
order cutting the partner first is a constraint conflict): the member's
holes, then the shared cuts it owns as open CommonLine centerline cuts
entered through the notch on the span's axis, then its remainder pieces,
each ramped in from the kerf the shared cut opened. Capture marks the
shared spans as tabs on the owned clean copy, so replay's contour
accounting proves each perimeter is cut exactly once; a lead that fits
at neither end refuses as UnsupportedGeometry naming the span, never
shortened. Material still comes from the drawing, so utilization,
quantity and overlap results do not change. Members are never
support-tabbed; locked or excluded members and broken groups refuse.
The CI Fiber post writes shared cuts in the cut-off form with a lead-in
and no G41/G42, and remainders in the contour form on their perimeter's
compensation side, named by a remainder comment. Cincinnati CL (whose
PreApplied mode offsets nothing) and Gravograph refuse such nests, as do
the desktop and console for any post without ICommonLinePostProcessor;
nothing falls back to a silent double cut. Plate > Arrange > Cut Common
Lines Twice keeps slice 1's behavior, persists with the plate and makes
an open plan stale.
Pre-post review now checks each span is cut once, on its centerline, by
the member cut first, and the rapid check treats a finished member's
remainders as an obstacle. Compensation start in void and cancel in
kerf are unconfirmed on the CI FIBER 4020; release waits on a 3/16
stainless coupon trial.

Nobody tabs every part, but tabbing by size is useful even on a plate
that has a support grid. Cutting Settings > Tabs now offers "Only tab
parts the support grid can't hold level" or "Tab parts by size"
(CuttingParameters.TabBySize), which ignores the bed and tabs each part
whose minimum-area bounding rectangle's narrow side is in the range.
The support grid choice still falls back to that range on plates with
no bed, as before.
The range fields become TabSizeMinWidth/TabSizeMaxWidth; their JSON
keys stay noBedTabMinWidth/noBedTabMaxWidth so saved settings and nests
read unchanged. TabsEnabled stays as the per-contour flag Plan Cutting,
Place Lead-in and drawing pins set on the parts they tab.
Saved user settings with "Tab every part" read as tabs by size from 0
to 9999, which tabs the same parts. Only the user's settings migrate;
a plate's recorded parameters and pins replay as planned.
Plan Cutting, Place Lead-in and the pre-post review all go through
SupportTabSettings, so they agree on which parts need a tab. A
size-tabbed part is held by any clear tab, so it is never a rapid
obstacle.

A cutout's lead-out ends in its slug, so the rapid after it always crossed
the cutout just cut and the strict search refused every plan with cutout
lead-outs. The slug is free and may drop or tip, so emission now marks that
rapid to raise the head, and the rapid check accepts a raised rapid that
starts at the lead-out's end and leaves its cutout exactly once. Cutouts
without a lead-out, or with an overcut, still leave from the cut head down.

A tab entered at a fillet joint trims back around the corner, so the cut
stops on one edge and starts on the other. Each straight lead took its own
edge's normal and the pair sat 150 degrees apart, reading as one bent line
through the corner. Both now take the bisector of the two ends' normals and
form the same V they form on a straight edge, falling back to their own
normals when either lead would not clear the part.

A support-tabbed part that no single tab can hold level may tip once cut,
yet its tabbed outside was crossable like any retained part, so Plan
Cutting could rapid back across a row of long strips. Its outside is now a
rapid obstacle, closed across its tab gap, in the search, replay, cut-off
insertion and the safest route.
Its fallback entries are ranked toward the next cut rather than steadiest
first, so a long strip can be left toward the next part, and the "cut those
two the other way round" rule applies only when the approach crosses no
other part.

A tabbed outside cut is trimmed short of its entry, but the trim only
handled lines and arcs: a round part's outline is one circle, so it was
cut whole. Plan Cutting counted it as tabbed and called the plan ready,
then the pre-post review found no tab and warned that the part may tip.
Cut a tabbed circle as an arc that stops the tab's chord short of its
entry, travelling the circle's own way.

Round holes are cut as sub-programs, which are never marked because they
may be shared, so the safest-route fallback could not raise the head for
the rapid into a hole: on interlocked layouts every such crossing stayed
a finding and the plan stayed unverified. A HEAD RAISE marker may now sit
directly before a sub-program call, raising the call's arrival rapid.
- Motion reader: a marked call raises its first rapid; each sub-program
motion records the part's own call that runs it.
- RaisedRapids marks the call when the crossing rapid is its arrival.
- Cincinnati CL keeps the marker with its hole call and writes M47 before
it; part sub-program dedupe now tells marked programs apart.
- CI Fiber raises before the hole's first G0.

Small parts on a coarse support grid (the help tutorial's 5 x 5 gussets
on a 2 inch grid) rest on one or two points, so no single tab could
steady them and every plan came back unverified. New cutting settings
now start "Tab alone holds parts up to" at 6; settings saved without the
field still read as 0, so existing settings keep their meaning.

With a pierce diameter set, every internal contour whose configured
pierce is inside the zone is resolved by flattening the cutout, finding
its pole and eroding it, and the search emits a part's whole chain again
on every expansion, so on parts with dozens of such holes almost all of
the planning time went there: three 1,600-motion parts took 41 minutes
and timed out in production. The resolution is a pure function of the
hole, the entry, the configured lead-in, the zone and the turn, so each
preparation now keeps it by contour ordinal and reuses it, unchanged,
across its emissions and copies. The same plate plans in 148 s.

Every part the support grid could not hold level got a tabbed perimeter
with the outside lead-out after its tab, and planning refused any lead-out
after its own open cut, so with a lead-out configured no such part could
be planned. Pre-post review already proves such cuts release nothing (the
lead-out stays out of the tab gap); planning now runs the same proof, so
planning and review agree and a lead-out that reaches into the tab is
still refused.

Small features got leads that ignored their shape: full 0.15 leads at a
shallow angle along letter strokes, stubs at the pierce zone's edge in
round holes that could be pierced in the middle, and a lead aimed at a
letter's far pole that ran longer than configured.
Plan Cutting now limits a lead to the feature's depth at its entry, where
a second wall becomes as near. The pierce-zone fallback goes there first
and otherwise aims beside the entry rather than at the whole cutout's
pole. Pinned contours keep their leads, and wide cutouts are unchanged.
Centred pierces exposed the line/circle tangent test: its absolute
discriminant tolerance called a radial line through a hole under about
0.056 radius tangent, reporting a false contact at the centre. Tangent
now also requires the line to stay at the rim, which keeps true grazes
as they were.

Trim refused the piece between two crossing cut-offs because a cut-off had
one start and one end, so a line could not be stopped short around a pocket
of parts without deleting it and drawing two. A cut-off now carries Gaps,
stretches between its limits left uncut: segment generation excludes them
like parts, so the line splits into segments that each take their own place
in the cut sequence. Trimming a middle piece adds a gap from one crossing
centre to the other (merged with any it touches), Extend near a gap's edge
closes it, and Swap Through-Cut refuses a junction a gap touches rather
than guess which side of the gap should run through.
Every reader of the limits treats a gap as uncut, so nothing waits for,
warns about or credits a cut that never happens: segment spans stop at a
gap, the cutting dependencies skip a part inside one, the clamp check
ignores a clamp inside one, the cutting-state and overlap stamps go stale
when gaps change, and a gapped line is never full span for the expected
remnant or automatic cut-offs. Gaps persist as an optional gaps array;
older versions ignore it and would cut straight through.

Plan Cutting spent most of its time on work that never changed the outcome:
many-holed parts paid quadratic shape-pair and ring-containment costs before
any search, every plate was captured twice, and failing plates burned their
whole budget in exhaustive fallback passes that never found a plan on 127
production plates.
- OverlapMaterial: skip native shape pairs whose bounds are clear by more
than the query allowance; gate polygon touch and winding tests on vertex
bounds.
- LeadMaterialSnapshot: gate ring enclosure tests on ring extents when
finding the perimeter and rejecting nested cutouts.
- CuttingPlanBatch: capture each plate once; the kept-order retry derives
from the same capture through CuttingPlanSnapshot.WithPreservedOrder.
- JointCuttingPlanSearch: end the kept-order full pass and the sequence-free
recovery and full passes after FallbackStalls (2) stalls' worth of
expansions when programs are regenerated; plates with only fixed programs
keep the exhaustive search so a refusal stays genuine.
On 127 archive plates (lead-ins cleared, 35" scrap cut-offs) total time fell
from 164 s to 102 s with identical outcomes; the problem-nest corpus gives
the same status and expansion count on every plate.

An arc lead-in meeting a straight window edge tangentially has a double
root at its joint. Rounding split it into two contacts a few 1e-8 apart,
or dropped it so the exact ray fallback reported the joint as an
uncertain contact. Either refused a valid entry, so N26-27U's windows
lost most of their entries and the plate never planned.
Treat a contact within 1e-6 of a joint its boundary passes through as
the joint, and let the exact line fallback skip ray hits at contacts
already recorded. The pinned-hole test now expects the other hole's
nearest entry rather than the fallback both runs used to share.

When no search finds a route that keeps every rapid off parts already
cut, Plan Cutting used to offer only an unverified safest route needing
explicit acceptance. Cincinnati's own software instead raises the head
for such a rapid. Now the safest-route fallback marks each planner-chosen
rapid that still crosses cut parts with a HEAD RAISE comment, and the
plan is Ready with every raise listed. The strict search never marks a
rapid, and the batch prefers fewer broken checks, then fewer raises,
then less travel, so a plate that can be cut head-down never gets one.
The reader flags marked rapids and the checker sets their crossings
apart, in replay and pre-post verification alike. The Cincinnati CL
post writes M47 before a marked rapid whatever the M47 mode (the
distance-based safety raise is unchanged); the CI Fiber post writes a
new Head raise block and refuses marked nests while it is blank, since
its raise code is unconfirmed. Rapids into locked programs, cut-offs
and hole sub-programs are never marked and keep their findings.

Plan Cutting ranked a convex corner first, but a corner rounded by a small
fillet had no corner vertex: its tangent joints ranked level with straight
edge midpoints, so travel decided and a large part (P230323-02 plate 8,
PT06, 0.015 corner fillets) started in the middle of a 64-inch edge. A start
there can leave a step where the cut closes after the head has put heat into
the plate; at a corner it is hidden.
A convex fillet tangent to straight edges at both ends, turning less than a
half circle and reaching no further along either edge than its length, now
makes its two joints convex-corner entries. Each carries its reach from the
sharp corner it rounds, so ranking counts it on both sides of that corner.
Longer curves, half-circle ends and inside fillets keep their tangent joints.
Every perimeter on that plate now starts at a corner; the problem-nest corpus
has no plate below its baseline.

Small parts such as 1.5" test squares on a 2" laser grid rest on at most
one grid point, so no single support tab can bring their center of
gravity inside the contacts and Plan Cutting warned "no single tab can
steady it" on every one. In practice a part that short stays in the
sheet on its tab, so the bed's contacts don't matter.
Cutting Settings > Tabs gets "Tab alone holds parts up to N long"
(CuttingParameters.TabHeldMaxLength, 0 = off, the default). On a plate
with a bed, a part the bed can't hold level whose length (long side of
its minimum-area bounding rectangle) is within the limit is still
tabbed, but any tab clear of inside corners steadies it, so Plan
Cutting, hand-placed lead-ins and the pre-post review warn only when it
has no tab at all. The setting persists with the cutting parameters and
is part of the plan state fingerprint.

Serial-number tags with 27 stencil-text cutouts never planned: contour
recovery stopped at 16 holes, a lone part never got recovery, and the
remaining search kept leaving letters on the wrong side so rapids ran
back across letters already cut. Recovery now handles up to 30 holes,
runs for lone holed parts, and first sweeps the holes in reading order:
by their far side along the way they spread, each left from its far side
(stencil pieces face the next piece), ending at an outside entry beyond
every hole, with a few expansions per hole. Parts within the old 16-hole
reach keep the search first, so their plans are unchanged.
The eroded pierce now steps down through shallower levels so each entry
gets a pierce on its own stroke's centre line, and leads to the entry the
planner aimed at (falling back to the nearest wall), which the sweep needs
to leave a letter from the right place.

Small text and narrow slots often have no entry where the configured
lead-in fits, so Plan Cutting refused them. When every entry of a cutout
fails, the planner now erodes the cutout inward (to the pierce clearance,
or nine tenths of its inscribed radius when smaller), pierces at the
eroded point nearest each ranked entry and leads straight to the closest
wall, with no lead-out. Letter strokes pierce on their centre lines; a
tapering feature pierces at its widest spot. The lead validator still
checks every candidate, and cutouts whose lead fits are unchanged.

Text cutouts on an ID tag sat a micro-inch below another letter's
baseline. The parity ray, offset a fixed 1e-6 above the test point, ran
exactly through that letter's seam vertex, whose two copies differ in the
last bit, so one edge counted and the tag captured as "Nested cutouts are
not supported material" at some plate locations but not others. The ray
height now steps until no vertex (or arc top/bottom) lies within a small
band of it.

Curved leads turned with the contour winding, which is backwards on outside
perimeters: arc lead-ins arrived against the cut, and Line + Arc / arc
lead-outs went the long way round on one winding. LeadTurn now gives the
arc's turn direction for emission, the pierce-zone check and the preview,
and the arc geometry mirrors with it.
At convex outside corners, curved lead-ins use the first-cut edge's normal
and arc lead-outs the last-cut edge's, whichever edge was picked.
ArcLeadIn gains SweepAngle (degrees, (0, 180], default 180) in the cutting
panel, settings, nest files and cut pins; older files read as 180.

With support tabs on and no support bed, nothing was tabbed and nothing
said so. A new no-bed width range (NoBedTabMinWidth..NoBedTabMaxWidth,
the short side of the part's minimum-area bounding rectangle) now picks
the parts to tab instead. SupportTabSettings.Analyze makes the choice
for Plan Cutting, hand-placed lead-ins and the pre-post review; without
a bed any tab clear of inside corners counts. With no bed and no range,
the plan notes that nothing was tabbed. Cutting Settings > Tabs gains
the range fields, and the values persist with the cutting parameters.

Converted part programs keep a source CAM's overcut: a hole's arc or a slot's
last line runs about 0.03 past the pierce along the first cut. The rapid check
only counted a contour closed when it ended exactly at its start, so every
overcut contour became an open fragment, the open-cut proof refused them, and
each part reported "Multiple interrupted/open cutting fragments" and an
unverifiable lead-out instead of being checked (P260810-02: all 50 parts).
ReleasedContourState now closes such a contour at its seam (matched at the
1e-6 seam tolerance, since a hole's two arcs carry centers ~1e-7 apart) and
lets the rapid leaving the overcut end ignore contact within that tolerance of
its departure. The nest now validates fully and reports the real crossings it
was hiding: rapids that cross the hole just cut.

Stock can arrive up to 1.5 in wider than nominal, so only the origin-side
edge is certain. A cut-off with a head-locked overcut cuts past the nominal
far edge with the head height locked, covering the oversize. With that lock,
Plan Cutting may start the far-edge segment at the far edge: overcut outward,
rapid back still locked, unlock, cut toward the origin. Without it the
direction stays fixed, as decided in Project Memory a20ea455.

sessions and used for new cut-offs.
Lock codes and machine behaviour with the head locked are unconfirmed.

Emission splits a contour at its entry with Arc/Line.SplitAt, which treat
a point within Tolerance.Epsilon (1e-5) of an endpoint as that endpoint
and start the contour there. The lead-in still ended at the entry point
itself, so an entry 1e-8..1e-5 from a vertex left that span uncut and the
plan's own verification refused it ("does not preserve complete directed
contours").
Imported PEP mounting holes hit this: two half circles whose stored centre
sits 5e-8 beside the chord's midpoint, so the closest entry to an approach
from straight below lands 5e-8 along the first arc from its start. Panel
doors were refused on every plate holding such a hole.
PreparedContours now snaps an entry 1e-8..1e-5 from its entity's start or
end to the exact vertex, for automatic entries, scrap pierce entries and
drawing pins alike, so the lead-in ends where the contour starts. Entries
already within 1e-8 are left as they were, so saved pinned programs
re-emit unchanged. Entries de-duplicate on the snapped point, and
near-corner insets keep the snap distance from both edge ends so none can
snap onto a reflex vertex.
A part with about 1,700 holes (P241017-01) never planned: material
capture paired every boundary with every other one and lead checks
scanned every boundary per lead, so both hit the 1M native query limit
and the plate fell back to an unverified best-effort plan.
- Material capture sweeps boundary extents along X and queries only
pairs the lead checks' per-pair clearance cannot skip, in the full
scan's order.
- Material with 64+ boundaries keeps a grid of boundary extents. Lead
checks, contour-joint matching and replay's contour accounting query
only nearby boundaries; ray parity reads only holes on the point's row.
- Only native queries that run are charged to the budget; skipped far
material no longer costs its full boundary count.
- The search looks up chosen holes and route ranks instead of scanning.
With that the plate plans Ready, but in 189 s: every step re-emitted
and re-checked all holes already cut. On parts with 64+ contours a
middle hole step now checks only the contour it adds, continuing the
completed-contour state its prefix left (ReleasedContourState.Continue).
It falls back to the full prefix whenever it cannot continue exactly,
and the last contour still checks the whole part from before it.
Isolated contour emission clones only the chosen contour.
P241017-01 now plans Ready in 5.4 s with an identical route, expansions
and rapid travel. Core and engine suites pass; the problem-nest corpus
matches the unchanged commit's outcomes and expansions.

Help > OpenNest Help (F1) and context F1 in Auto Nest and the CAD Converter open
the bundled opennest-help site in a single WebView2 window on its own UI thread.
Both packaging scripts install the opennest-help release pinned in
scripts/help.json, verified by SHA-256. The missing lead-in finding now says
the contour is missing lead-in geometry.

With the pre-post risks acknowledged, an unplanned blank reached the
Cincinnati and engraver posts, which created the output file before
refusing: an existing program at that path was emptied and the desktop
had no handler for the refusal. Both posts now check every part before
creating the file, and Post shows the refusal like the multi-file path.
A display tail marker is now honoured only as one marker ending the
part's own program, followed by a rapid and the outline alone. A marker
inside a sub-program or followed by real cuts is refused by posts and by
executed reads, so cuts after it can never be dropped from both
verification and output.
Enclosure was tested at one point per entity, so a round cutout starting
on the blank but running past its edge, or a cutout whose corners all sit
on an L-shaped blank while an edge crosses its notch, reached an
unverified plan that warning acceptance could apply, cutting into or past
the never-cut edge. Every cut is now sampled along its arcs inside the
outline and must not cross or touch it, and the material capture names the
display perimeter when a cut crosses it.
Place Lead-in built its contours from cut-layer entities only, so on a
blank the largest cutout looked like the outside and took an external
lead pierced on the blank; committing then regenerated the part with the
outline as a cut perimeter. The legacy whole-part strategy did the same.
Both strategies now refuse a program with a display perimeter and leave
the part unchanged, and Place Lead-in explains that such a part's cutouts
get their leads from Plan Cutting instead of selecting it.
An applied cutting program for a display-perimeter blank held only its
cutouts, so the part shrank to them: a 30 x 20 door reported an 11.5 x 20
extent, overlap and the plate view lost the blank, and running automatic
cut-offs afterwards added lines straight through it.
A complete emission now ends with a display tail: a marker comment, a
rapid to the outline and the outline on the display perimeter layer. The
part keeps the blank's bounds and material, so later cut-offs still have
nothing to cut and the door plans again as before. Nothing executes the
tail: executed reads stop at the marker, so search, replay and the
pre-post review see only the cuts, and cut time, the rapid display and the
cut simulation leave it out. DisplayPerimeterTail.ForPosting gives posts
the program without it and refuses an unplanned display perimeter.
