Thin extrude caps are certified by the curves the wall follows, so a sketch attached to a cap survives switching between solid and thin (#1519).

* Name a side drawn on several sketch curves by all of them
An extrude named each side wall after the one sketch curve its profile
segment lies on. A wall along two coincident lines (squares drawn edge to
edge) or along collinear lines merged into one profile segment had no
single curve, so it was named from geometry and could not carry a sketch
attachment. One sketch extruded up and down and joined (the logo) refused
a sketch on every one of its side walls.
Such a side is now named by every curve it lies on, in sketch order: the
first is its name, the others aliases. The set is fixed by the sketch, so
the name is exact. The refusal message no longer blames merged faces.
Adds the reported logo design and a synthetic up-and-down join to the
action-matrix designs, and a regression test that sketches and extrudes on
every flat face, fresh and after save and reopen.

Sheet metal rims and bend ends attach by name (<panel>:rim.<edge>, <flange>:rim.bend0/1), as do face profiles from sheet faces. A plain or counterbored Hole square to a panel is machined into the flat pattern. Boss, Lip, Rest and Snap Fit keep the body's history and name their own faces. Hole tools name their faces by the part they cut, and pattern copies as copies. A pattern's repeated fillets keep the body's history. Loft sides are named by their section curves. A piece Offset Face moved off its face's plane attaches by its own qualified name. Sides of a profile grown to overlap a flush body keep their sketch line's name, so walls a Join merged take a sketch (#681). Face sketch 75% -> 90%, offset plane 75% -> 90%, press-pull/extrude 64% -> 85% in the action matrix; baseline blessed.

A flat face that no construction certificate names on its own now attaches by its exact history name (a new lineage face certificate): cut walls and floors, chamfer faces, each pattern or mirror copy, side walls a Join merged, and the pieces a later feature split a face into. Construction certificates still come first; a seed keeps its certificate when it is patterned. Two flush extrudes of one outline joined end to end keep their exact history in the prism boolean. Face sketch 52% -> 71%, offset plane 52% -> 71%, press-pull/extrude from face 41% -> 60% in the action matrix; baseline blessed.
Fixes#491, fixes#492, fixes#493, fixes#557.

A profile traced over a face sketch's projected boundary left the extrude's caps and sides without an exact planar source, so a sketch or offset plane on the new top face was refused. The drawn curve is now the edge's source where it covers a projection. Clearer fixed-plane message; regression tests in the engine, UI harness and design corpus, plus a corpus-wide flat-face attachment check (known gaps under #491-#495).

* Sketch on a cylinder primitive's caps (#420)
A solid.cylinder's caps carried no construction certificate, so a sketch
on its top or bottom was refused unless fixed:true (#420's crossed
cylinders, built from primitives).
- kernel: FaceSource::CylinderCap { producer, high, plane };
Body::with_cylinder_certificate turns a cylinder's two extrude caps into
certified caps. kernel::cylinder's output is unchanged for its other
callers.
- doc: FaceCertificate::CylinderCap { high }, named F<id>:top / F<id>:bottom
as the cylinder's face names already are; New Body and Join cylinders
are certified, shells carry it as their planar source.
- format 15: designs can store the new certificate kind; version 14
designs need no change, and older builds ask for an update instead of
meeting an unknown kind.
Tests: top and bottom attachments follow a height and base edit and a
reopen; crossed joined cylinders keep both caps attachable; a shelled
cylinder's floor keeps its cap identity; malformed certificate JSON is
refused.

Record ownership transfers in the timeline so earlier Join/Cut membership,
world placement, machining data and styles survive component moves, edits,
independent copying, undo and reopening. Preserve pending positions in history
snapshots and keep constructor transfers ordered during feature redefinition.
Retain shallow sheet pockets and exact planar intersection islands through
unfold/refold, with depth-aware flat previews and DXF export. Store explicit
3D wire coordinate spaces and migrate known legacy provenance without moving
saved points or analytic fits.
Infer unique eligible cylindrical Emboss targets, align Revolve manipulators
with actual extent geometry, and discard obsolete preview errors after input
correction. Certify constructed and immutable imported face styles using exact
source metadata while preserving legacy face names. Upgrade designs to format10
with bounded validation and geometry-preserving legacy migration.
