With a pierce diameter set, a perimeter none of whose configured lead-ins keeps its pierce
clear (a lead shorter than the zone radius, or neighbours closer than it) was only rejected.
Plan Cutting now looks for a pierce in the open scrap around the part instead.
- ScrapPierceSearch (Engine): the window four zone radii around the part, minus every nearby
part's clean material grown by the zone radius and a margin (ClipperBridge, conservative
flattening); the clear point nearest each ranked perimeter entry is a candidate. Other
parts' cutouts count as scrap, the part's own holes do not. With no clear scrap, the
PolyLabel pole of the free scrap is the best effort, and its shortfall is reported.
- ContourChoice.Pierce / PreparedContours.ScrapPierceEntry: the planner's choice carries the
pierce; the emitter cuts a straight lead from it to the nearest perimeter point and still
reads nothing but the contour and the choice.
- Every candidate passes the lead validator like any planner-chosen entry; pinned perimeters
keep their pins and warn. Without a pierce diameter nothing changes.

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 converted outline whose seam closes within the admitted 1e-6 gap could
only be entered at its seam: entered anywhere else, the arc after the
seam started off its own circle and every emission was refused as an
inconsistent radius. The search then spent its whole budget on that
part and the plate never planned. Emission now bridges the gap with a
straight move and cuts the arc as drawn; the verifier already admits
that slack. An entry on the seam vertex is left as before.
Each prefix of a part re-checked its earlier contours' leads against
every other part's material. One search now remembers each verdict by
the lead curve's exact bits and the material's reference, charging the
same native query budget; replay never uses it. On the reported plate
the memo alone gives a byte-identical result in 57 s instead of 12 min 47 s;
with the seam fix the plate plans Ready in about 17 s.

The 5.5 pinned-entry shortcut in ContourEntryFeasibility looked up the
choice's contour before the probe's own validation, so an owned choice with
an out-of-range contour ordinal threw instead of returning Incomplete as it
did before. The lookup now runs only for an ordinal inside the preparation.

A drawing-pinned contour is now a fixed emission like a locked program. A
regenerated placement maps its execution motions onto the emitted contour
choices (one group per choice after the program's scribes, opened by its
rapids) and owns as fixed the lead-in, cut, lead-out and tab of every pinned
contour; the rapids between contours, including the one into a pinned
contour, stay the planner's and strictly checked. If the motions do not
split cleanly into one group per choice, nothing is treated as fixed.
So a pinned lead that meets another part's material or its own part's no
longer rejects the candidate: the feasibility precheck accepts a pinned
entry as given, the search keeps it in place, and replay reports a FixedLead
warning naming the part, cutting contour, pin and the part hit, with the
advice to increase spacing or switch off drawing pins for the part. The
plate is UNVERIFIED and needs acceptance; the lead is never shortened and
the entry never moved. The unpinned control and the same plate with pins
off are Ready.

No-hole parts now choose the outside entry through the S03-S08 pipeline
at the part boundary: rank the native catalogue toward the NEXT cut's
placed-material centre, lazily certify each emitted lead with the shared
validator, cap at maxEntries with side coverage. The next cut is the
next unfinished part on the supplied order (re-read after every
learned-order replan) or, in sequence-free fallback, the nearest
dependency-ready remaining part with stable ordinal ties; the last part
has no target and ranks by tier then arrival distance — never the plate
origin. Target and arrival are converted to prepared LOCAL coordinates
exactly once; geometry is already rotated.
The look-ahead rank survives Follow's ordering: children sort by
nearest source first (the sequence-free tour stays nearest-first), then
contour, then the selection rank — plain OrderBy(Distance) can no longer
undo the facing. Measured fixture (three squares, 0.15 leads, origin
start): legacy cut every sheet at its arrival-nearest lower-left corner
with 10.5-unit cross-sheet rapids totalling 21.0; look-ahead cuts the
+X-facing corner with the same 21.0 total but each inter-part rapid now
starts at the facing edge instead of trailing across the whole sheet.
Uncertain validator answers are never precheck-refused: they skip the
selected slots but flow to the emitted-prefix Check and complete replay,
which stay the authority — a refused-looking incomplete is reported,
not hidden. A fully evaluated catalogue with no fitting lead surfaces
'No tested lead-in fits on part N, contour M'; budget exhaustion stays a
budget finding. Lead prechecks count separately from DFS expansions; the
pipeline itself is one counted expansion per contour. Full backtracking,
dependencies, locked/fixed programs, cutoff handling, emitted-prefix
Check and complete replay are unchanged; budgets and CuttingPartOrder
untouched. Hole parts keep the legacy path until S12.
ContourEntryFeasibility: one adapter over the EXISTING LeadPathValidator
for one owned candidate — emit through the S06 diagnostic seam, read at
the placement position, certify emitted lead-in AND lead-out against ALL
placed material. Only complete+clear qualifies; blocked and incomplete
keep their reasons as distinct verdicts (an incomplete check never
reads as clear). Not a new collision implementation and not a plan
approval: NoLeadIn passes vacuously and the complete-plan missing-lead
check still runs later; rapids and pierce clearance stay with their
existing checkers.
One instance is one captured planning attempt: verdicts cache per exact
owned choice + node context (settings/placement are fixed per instance),
never static, never across instances. Lazy: only the checked candidate
is emitted; EvaluationCount counts validator executions for cost tests.
Foreign/malformed emissions are Incomplete verdicts with reasons, never
crashes; cancellation propagates without poisoning the cache. No search
changes and no broad-phase skips.
