Sessions and Activity
FFI/language binding exploration and design day. Fractal type-IR architecture expansions with new language projectors. Motif mathematical structures work.
fractal: 2 sessions
motif: 1 session
Key Work
- fractal: Comprehensive type-ir and projector architecture survey (118 active projectors); FFI generation design exploration; new language support:
- Gleam projector implementation (46 tests, bindings/FFI generation)
- ReScript projector implementation (35 tests)
- Wasm-bindgen projector implementation (44 tests)
- General FFI-IR architecture design with 5 variant forks and WIT (WebAssembly Interface Types) deep analysis
- motif: Private mathematics project work (structural invariants across fields)
Delegated Tasks
Total tasks completed: 3 (type-ir survey, gleam projector, rescript projector, wasm-bindgen projector, FFI-IR design)

Observations
- Major new capability emerging in fractal: language binding generation via type projectors
- FFI-IR design represents new architectural direction for cross-language interop
- Test coverage strong on all new projectors (35-46 tests each)
- Gleam/ReScript support expands fractal's multi-language story significantly
- Clean working tree; multiple features integrated and tested
Projects Touched
- fractal — API framework, type projectors, FFI/binding generation, new language support
- motif — a private mathematics project, structural analysis
