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.

The repo mixed variants such as center/centre and color/colour, so a
name could be spelled either way and searches missed half the hits.
Standardize on the US spelling, matching .NET's own APIs (Color, Center).
Wire values owned by other systems keep their spelling: the material
ledger's "Cancelled" hold status and GitHub's "cancelled" job status.
No behavior change beyond the spelling of a few status messages.

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.

A plate of tags with arc-outline digits found no plan, although each
cutout had a clear entry. Eroded pierces were offered only when no
configured lead fit, so a letter with one fitting lead on the wrong
side stayed stuck with it, and an uncertain lead check skipped erosion
altogether. Recovery also spent its allowance on the outside entries
and accepted the first it reached, leaving a part on a side the next
rapid had to cross it from.
Count uncertain leads as no fit. Give recovery a last, separately
funded try that adds eroded pierces for the outside entries ranked
ahead of the first reached, and hold back routes that end facing away
from the next cut until then. Drop a lead that touches only in the
whole emission, where rounding moves it, rather than rebuilding the
same chain. Plans reached from their best entry keep their entries.

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.

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.

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.

Plan Cutting is now the only automatic lead-in assignment, and parts the
support grid cannot hold level are reported wherever they lack a
steadying tab.
- Remove Assign Lead-ins (plate and nest), LeadInAssigner, the lead-in
tool's Auto-Assign button and the Auto Tab size range; old settings
with autoTab sizes still load
- Manual Place Lead-in tabs the clicked entry when support tabs are on
and the grid cannot hold the part (SupportTabSettings)
- New PartSupport finding: Plan Cutting replay and best-effort plans
warn when a drawing pin, a lead-in that does not fit or no single tab
leaves a part unsteady; the pre-post review checks each placed
program's outside tab gap. These warnings replace the advisory
weak-tab notes; only the inside-corner tab note stays advisory, and
never for a pin
- Pinned perimeters keep their pin but carry the support analysis
- Draw grid points as pixel-snapped squares without anti-aliasing
- Post fixtures build lead-ins through a test-only TestLeadIns helper
- Docs: support tabs, pre-post verification and planner notes

Remove a private part reference from the lead-in notes, fix the Options and
New menu paths, say that release ZIPs never auto-update, describe current
Cincinnati CL ordering, clamp validation coverage and empty-plate saving,
list every built-in engine, and drop internal decision labels.
Thick plate pierces leave a crater wider than the kerf. CuttingParameters.PierceDiameter
(Cutting Settings > Pierce Diameter, 0 = off) requires every lead-in pierce to keep half
of it from all part material: its own contour, its holes and every other part.
- LeadPathValidator checks the zone during Plan Cutting candidate checks and final
replay; fixed emissions warn as usual. No-fit findings explain the zone.
- PierceZoneReview reports Pierce zone warnings before posting for leads from any source.
- Holes whose configured pierce is inside the zone move it toward the hole's PolyLabel
pole (round holes: the centre), as close to the contour as the zone allows; a hole
too small for the zone is pierced at its pole and the shortfall is still reported.
- Straight corner leads and round-hole clamping use the larger of PierceClearance and
the zone radius. The manual lead-in preview shares the Core rules.
- Persisted through the DTO, owned copies and state fingerprint.
Perimeter fallback is not included; see docs/geometry/pierce-zone.md.

A tab trims the perimeter short of its entry, but the lead-out was still
generated from the nominal entry point. An arc lead-out therefore started
off its own radius (ExecutionMotionReader rejected it as inconsistent), and
a line lead-out ran diagonally back toward the entry.
Every lead-out style on a tabbed perimeter now leaves from the trimmed
cut's actual end, on that entity's normal, so arcs are tangent and the tab
gap stays uncut. Untabbed contours and the corner run-out rules are
unchanged. Malformed legacy output is still refused, never refit.
Red before the fix: the three tabbed arc cases threw "Arc has zero or
inconsistent radius" and the line case ended at y=5 instead of 4.8. Keeping
the entry's normal at the actual end fails the curved-perimeter case.
A straight lead-in at a convex outside-perimeter corner now runs along the
extension of the edge cut first, so the torch enters on that line and keeps
cutting it. The result no longer depends on which of the corner's two edges
auto-assign or the manual cursor picked, which made placement flip between
straight and 90 degrees. The approach angle is ignored at such corners.
The straight lead falls back to the first-cut edge normal when its pierce
would be closer than PierceClearance to the contour (very flat or tessellated
corners). Reflex perimeter corners bisect the notch. Line lead-outs run on
straight past a convex corner along the last-cut edge, except on tabbed
perimeters. Program generation and the Place Lead-in preview share
ResolveLeadIn/ResolveLeadOut.
