Eyes eyes-bt-detail-layer, session self-2026-10-11-ag2, weighted by the operator's workflow:
"expressing the form elegantly with as few control points as possible, then I go and start
cutting into it for all the hard surface details".

The fidelity wall was the SDF program's own fit, not the remesher; the hard
crease with Newton projection gives a crisp rim; flow and UVs remain open.
Keeps the ~100-line Instant Meshes patch (BSD fork, against 7b31608).

Both run headless; both give clean quads; both stop at the same fidelity
wall on the knife-edge wing. Instant Meshes can take an external cross
field through its existing constraint path.

One continuous shell fitted by least squares: closest fit and best flow so
far, three UV islands, a two-number edit; hard edges and cage design gaps.

Operator-approved spike on Dexter Quiet: exact-Hessian cross field with
crease and ridge constraints aligns well; the numpy position field and
extraction did not converge; CC least-squares cage fitting to the field works.

The compact Dexter Quiet description lowered three ways (OpenSCAD plus
automatic cleanup, a bmesh script, Geometry Nodes) and judged against the
operator's bar. Serves the brush-tree target revision.

Clean unbroken topology flow, part-coherent low-distortion UVs, one-segment
bevels with face-weighted normals; her bevel test render as the reference.

Opus rebuilt a control hull, Dexter Quiet (twice) and Headliner as
OpenSCAD and as Geometry.Csg brush lists, with its own measurement
tools. Outcome A by the plan's table, with qualifications. Serves the
brush-tree forks openscad-surface, fitting-home and vocabulary-growth.

The ends of the brush-tree campaign: OpenSCAD-shaped CSG trees authored
in Blender through brokkr-ctl, with the typed brush tree as the one truth.
Sixteen invariants, scope, canonical implementations, evidence, and the
identity/lifecycle/authority table. No cut plan.

Eyes pass 2026-10-10: Epic's ImpostorBaker, open-source ports, Amplify and
Unity toolkit impostors, relief/true impostors, depth compositing, where
shipped titles use them, and the absence of marcher-to-atlas systems.

Eyes pass 2026-10-10: Chisel surfaces and UVs, hg_sdf blends, Dreams
(full slides), Claybook, Keeter MPR and Fidget, mesh distance fields, and
this crate's current state.
