Restructure to engine-only contents. Application code (Topolei.*
namespace, canvas-rs / render Rust crates, Main / ProbeTest, naga IR
pipeline, Selection / Subobject / Trace / Obs.Ctx hypothesis stack,
cells-spec / HYPOTHESES / STATUS / NAGA_IR_PLAN docs) moves to the
sibling repo max/topolei.
What moved:
- `Topolei/Cubical/*.lean` (22 files) → `CubicalTransport/*.lean`
with namespace `Topolei.Cubical.*` renamed to `CubicalTransport.*`.
Fully-qualified test types `TopoleiCubical{FFI,Property}Test` →
`CubicalTransport{FFI,Property}Test` for consistency.
- New root file `CubicalTransport.lean` re-exporting all 22 modules.
- Lakefile: package `cubicalTransport`; lib `CubicalTransport`; only
`cubical-test` and `cubical-bench` exes (no GPU link path).
The split criterion: anything an AI shortcut could break that would
cascade-corrupt downstream proofs lives here. Anything that would
only break the application stays in the topolei interface repo.
cubical-test passes 62/62 (smoke + properties) on the renamed engine.

Implements the cells-spec vision: a computation space that preserves
auditability, correctness, interactivity. Phase 1 (Lean kernel +
naga-IR Rust backend) is closed; foundation hypothesis stack
(Selection H1+H2, Subobject H3, Trace H5, Obs.Ctx C2, Cubical.Trace)
landed.
Highlights:
- Cubical-HoTT syntax + value/eval/readback in Lean
- naga-IR pipeline (no GLSL string crosses FFI; 17/17 probes pass)
- Honesty audit: every non-transport (sealed cells, vertex shader,
Y-flip, presentation conventions) is documented as such
- Polymorphic Trace α as free monoid; Cubical.Trace gives
CTerm → Trace CTerm by structural fold (homomorphism = definition)
- Selection as Huet zipper; Subobject as Boolean algebra over WCell
- All theorems proven; the proof IS the implementation
See STATUS.md for the resume guide.
