Lean Action CI / build (push) Waiting to run
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.
