Placements (entity lookups, intersections, String labels, projections)
recomputed per view() and per mouse-move hit-test, with overlay re-clones
and 2-3x offset recomputes. New constraints_epoch bumped on every set
mutation/visibility/undo/DWG-load (plus new set_constraint_enabled API);
single-slot Arc<[GlyphEntry]> memo on an 11-field key (hover/selection
excluded); overlay de-cloned/de-duped to the single geometry source;
hit paths reuse the cache.
Tests:
- cached_glyph_placements_hit_returns_same_arc: same-key Arc identity
- cached_glyph_placements_invalidated_by_metadata_edit: edit + selection change yield new Arc
- glyph_hit_test_entries_matches_precomputed_boxes: shared hit-test helper
Bench (cargo bench glyph, 60 constraints): 8.18us -> 0.05-0.15us (~55x).
A/B reference deleted.
#1415 made a dimensional Distance keep a negative value's sign in the
parameter while the geometry uses its magnitude (and a zero fold the
points together), but left the value-domain test asserting the old
refusal. Assert the new reading, and keep the radius refusal covered.

Symmetric held the connecting direction perpendicular to the axis with
the kernel's angle-based Perpendicular, which locks its turn side at
construction: a point starting far from its mirror image had to swing
the pair through the axis direction, the residual wrapped, and the
solver stalled with the point unmoved. The perpendicularity is now the
projection of the pair onto the axis direction being zero, a polynomial
residual the solver follows from anywhere. Circle centers and ellipse
centers use the same equation. tests/parametric_constraints_solve.rs
symmetric_constraint_mirrors_one_circles_center_across_the_axis_line
passes again.

Point & line and 2Lines take a text baseline or an ellipse axis as the
line; a zero value folds the points onto the first one; 2Lines turns the
second line about its start. The Properties Constraint section edits
Constraint Form (Dynamic on the *ADSK_CONSTRAINTS layer, Annotational on
the current layer), Reference (driven constraint in parentheses whose
parameter follows the measurement) and Description (stored with the
parameter and the native variable). Dynamic dimensions keep a 12 px text
and 8 px arrows at any zoom, drop trailing zeros and show formulas as
`fx: len=d1*2`; the hidden constraints layer stays out of the layer lists.

DCFORM sets the annotational or dynamic form and continues into the
DIMCONSTRAINT option prompt, whose wording and last-used default match the
reference. -PARAMETERS manages parameters from the command line; a
double-clicked constraint dimension opens its value prompt. Dynamic
dimensions rescale on every camera change and their display overrides stay
out of the saved file. A driving dimension between an entity's own ends no
longer has its length retained, so a new value moves the second point along
the dimension axis; parameter edits hold the first constraint point.

DCALIGNED opens with `[Object/Point & line/2Lines] <Object>`. Point & line
asks `Specify constraint point or [Line] <Line>:` then `Select line:` (or the
line first and `Select constraint point:`), measures perpendicular to the
line from the constraint point to the line end nearest to it, and stores a
directed distance with the line as direction reference. 2Lines asks
`Select first line:` and `Select second line to make parallel:`, adds a
Parallel constraint solved with the first line pinned, then measures on the
solved geometry between the nearest ends. Unsupported line picks report the
reference's message; the same measurement again reports `The constraint
already exists on the selected objects.` and ends the command; an invalid
expression reports both reference lines and asks again.
The offered default and seeded expression carry twelve significant digits;
a typed value moves the second point (or the other object) while the first
point and its measured line stay, negative values keep their sign in the
parameter and use their magnitude, zero folds the points together, and the
dynamic dimension's origins follow every solve. The lock mark sits after the
text, a selected dynamic dimension shows triangle grips at its points and the
text square, and its Properties show the Constraint section (Name and
Expression editable) plus Text rotation.

Every dynamic dimension gets a DIMSCALE override for 12 px text, refreshed
per zoom band, at creation and after load. A SCALE/ROTATE of an entity whose
own end points a driving dimension measures now pins its second constraint
point so the dimension moves the first end, as the reference does.

The dynamic dimension of a dimensional constraint is now linked in the
drawing file (AcDbAssocDependency + AcDbAssocDimDependencyBody on the
constraint node), reread on load, hidden by DCHIDE/DYNCONSTRAINTDISPLAY
and never plotted; it carries a lock mark before its text. New
CONSTRAINTNAMEFORMAT and DYNCONSTRAINTDISPLAY variables and the
DIMCONSTRAINT option front end. A transformed entity whose own end points
a driving dimension measures keeps only the first constraint point, so a
scaled line returns to its dimension value.

- resolve_point, set_polyline_vertex and the solver's point_for_marker
treat the marker one past the last vertex of a closed polyline as
vertex 0, the way line_segment already did. Equal (#1366), the axis
pre-alignment (#1365) and the transform pin (#1361) address a picked
segment's end that way, so on the closing segment they either refused
the pick or pinned nothing.
- Page-setup dictionary keys compare case-insensitively: page_setup_save
replaces "site" when "Site" exists instead of adding a second entry
(PSETUPIN counted it as replaced, #1344), delete and rename match the
same way, and a rename that only changes case is allowed.

Equal was applied through a generic gather-then-apply flow and, with the
default size-retaining solve mode, never changed anything: the solver
held both sizes and the relation could not be met. Now:
- GCEQUAL joins ECONSTRAINT and GEOMCONSTRAINT Equal; both objects are
picked inside the command (`Select first object or [Multiple]:`,
`Select second object:`; Multiple gathers `Select objects to make equal
to the first:`), a selection made beforehand is not used, a miss says
`No object found.` and re-asks, an unsupported object or the same object
twice is reported and re-asked, a repeat is refused.
- The follower is resized in place before the relation is added: a line or
straight polyline segment keeps its start and direction and its end
moves to the first object's length; a circle or arc keeps its center and
takes the radius.
- During edits the side that is not being edited follows the same rule:
its size is not retained, its start (or center) and other vertices are
held and its direction kept, so only its length or radius changes; a
chain of Equal relations follows along.

- acadrust 7ea4247: clamped-knot degree and MINSERT reservation fixes
(cadcodec #47). cadkernel a0b962a: dogleg fails on a non-finite
Jacobian (cadkernel #66) and pins the same codec rev, so one acadrust
stays in the graph.
- The axis re-alignment from #1361 retains its transformed length through
retain_segment_length, which holds a zero-length segment with per-axis
differences instead of a P2PDistance whose gradient is NaN there.

The temporary end-point pin of a transformed Horizontal/Vertical entity is
paired with the length the transform left it, so a scaled vertical line
stays scaled while a rotated one stays vertical at its rotated length.
Co-Authored-By: Claude Fable 5.1 <[email protected]>
10) A transformed entity with a Horizontal or Vertical relation keeps only
its end point where the transform put it; the rest re-aligns to the
axis at the retained length, so a rotated vertical line stays vertical
below its moved end instead of the whole-entity pin contradicting the
axis and leaving the constraint unmet.

9) When an edit contradicts a fixed point together with another constraint
so that the only solution collapses the entity (a rotated line with a
fixed start and a Vertical relation), the entity returns to its pre-edit
shape instead of degenerating, as the reference does.
Co-Authored-By: Claude Fable 5.1 <[email protected]>
8) A moved entity that a Fixed holds only in part no longer pins its free
points as hard anchors: they stay where the edit put them unless another
constraint on the entity (e.g. Vertical) moves them, so the fixed point
holds and the solve no longer fails when the two disagree.

1) FXCONSTRAINT (and the new GCFIX name) prompts "Select point or [Object]
<Object>:" — a pick fixes that constraint point; Enter or O asks for one
line, polyline segment, circle, arc, ellipse or spline; misses and
unsupported objects report the reference messages and re-prompt.
2) Point, block, text, MText, attribute and table insertion points are
addressable constraint points.
3) Re-applying Fixed to the same point or object reports that the constraint
already exists instead of adding a duplicate.
4) A persistent Fixed holds its pre-edit geometry through MOVE, ROTATE,
SCALE, STRETCH, grip and Properties edits: fixed points stay, free points
of a partly fixed entity follow the edit, and size retention skips fixed
entities.
5) Object mode on a polyline fixes the picked segment (natively persisted)
instead of the whole polyline; arc segments pin endpoints, center and
radius.
6) Ribbon label "Fix" with a padlock icon.

Retaining a line's length added a P2PDistance constraint, whose gradient
divides by the current distance. For a zero-length line the solver got a NaN
Jacobian and its SVD fallback never returned, freezing the editor (e.g.
ECONSTRAINT on a line drawn by clicking one point twice). Hold coincident
endpoints together with per-axis differences instead.
Control-point splines read without knots are given a degree their control
points can carry (at most n - 1) and a clamped knot vector when a drawing
loads. Generating knots for fewer points than the degree underflowed during
DWG write: a panic in debug builds, an unbounded allocation in release, and
reachable from autosave. A lone control point with no knots or fit points is
purged as corrupt.
