New and BOM import give a new nest the machine clamp rail from
clamps.json when it is enabled, converted to the nest's units; with the
default (off) settings nests are created exactly as before. An
unreadable or partly invalid settings file warns once per session.
Nest > Clamps... edits the current nest's rail: clamp width and depth
and a sorted list of X centers with Add/Remove. OK applies the rail to
every plate (Cancel discards the edits); Load Machine Defaults only
fills the dialog; Save as Machine Defaults writes clamps.json at once
and is labelled as not undone by Cancel. The dialog refuses to open
while nesting or a plate action runs. Its decisions live in the
Linux-tested ClampRailEditor; the form only renders and forwards input.
PlateView draws clamp zones as translucent hatched amber rectangles
over the sheet and parts and repaints when they change. They take part
in no hit test, selection or sequencing.
Write the nest's machine clamp rail under plateDefaults.clampRail
(width, depth, centers) so plates created or resized after a reload
still get the clamps. The key is omitted for nests without a rail, and
a missing, empty or malformed rail loads as none while each plate's
saved zones still load.
On load a plate follows the rail again only when its saved zones are
exactly the rail's for that sheet; other zones are kept as written.
The empty-plate filter now drops an empty sheet whose zones the saved
rail recreates, so the editor's trailing empty sheet is not written
for every clamped nest; empty sheets with other zones are still kept.
Add the additive per-plate clamps array (id, x, y, length, width) to the
nest DTO with writer and reader support. Files without the key load with
zero zones; an individually malformed entry is dropped while the rest of
the nest loads. A plate carrying only clamp definitions now survives the
writer's empty-plate filter; genuinely empty plates remain omitted.
Format documented in docs/nest-file-format.md.
The dialog buried its verdict in a scrollable text box that restated the
same numbers per plate behind a paragraph-length warning. Replace it
with:
- a bold colored status line stating exactly what Apply will do
(Ready / Blocked / No new cut-offs / Error with the reason);
- the occupied span, used span, separator X and retained tail as
compact caption+value cells with tooltips instead of four sentences;
- the warning paragraph reduced to one amber line with the full text
in its tooltip;
- a per-plate table (cut-offs, spans, tail, Ready/Blocked/No change)
for the All Plates command, replacing repeated text blocks;
- the details box now lists only issues and notices, prefixed by plate
number when planning a nest, instead of echoing every measurement.
Planning, preview, apply and rollback behavior is unchanged; tests and
the cutoffs document follow the new presentation.
Nests converted from another CAM system carry its seam overcut inside the
clean contour: the last cut runs on past the contour's own start along its
first cut, then a straight jog returns to the start. The ring then touches
itself at its seam, so neither the cutting planner nor the overlap analyzer
could certify it and the whole plate refused.
SeamOvercut recognizes exactly that shape (same line, or same circle and
direction) and trims it from an owned copy; the retraced tail encloses no
area, so material is unchanged and the drawing is never edited. Any other
self-contact still refuses. Arcs of one circle whose centers were each derived
from their own endpoints agree only within Epsilon, so their spans are now
compared at the seam tolerance: shared spans still refuse as overlap, while
arcs that only meet at a joint or lie apart no longer do.
Plates with parts nested in other parts' cutouts then failed to route, since
the host is cut last and every straight approach from the middle of a crowded
cutout crosses a finished neighbour. CuttingNestedOrder tours each host's
inner parts as one run ending beside the host's own contours, hosts follow
the parts beside them, and learned rules still win. Outside entries are
ordered by clear sight lines to the next cut, the look-ahead toward a host is
its nearest contour point rather than its centre, a cutout containing the
arrival point is routed from that point, and a pass that teaches an order
rule ends the round instead of repeating the blocked approach.
Tests: SeamOvercutTests and CuttingNestedOrderTests; the cutting-planning,
diagnostics and overlap tests in OpenNest.Tests pass (1023 passed, 6 skipped).

Report, dialog and diagnostic text across post verification, cutoff
planning, alignment and cutting-plan review repeatedly told the user
what checks weren't (safety certifications, proof, guarantees) instead
of what to do. Reworded these to state the same caveats affirmatively
(inspect X, confirm Y, review Z) without changing the underlying
safety guidance, and updated the tests/docs that pinned the old wording.
Lets the desktop app self-update like CncSender, but only restarts after
the user confirms via a clickable status-bar prompt -- an open, unsaved
nest must never be discarded automatically. The feed URL is a blank-by-
default, per-machine setting (File > Options), since it's operator
infrastructure that doesn't belong in source control; Deploy-OpenNest.ps1
packages releases for whatever feed host/path the operator supplies.
