REL1 Inductive.lean + Rust dispatch + 9 new smoke tests (25/25 + 46/46)
Inductive.lean (new module): schema combinators (mkSchema, mkCtor,
mkPath) and canonical schema instances:
- Plain inductives: natSchema, boolSchema, listSchema
- HITs: s1Schema, intervalSchema, propTruncSchema
Plus type-level helpers (CType.natC, listC, s1C, …) and term-level
ergonomic builders (zeroC, succC, nilC, consC, baseC, loopC, …,
natLit, natElim, boolElim, listElim).
Rust kernel (native/cubical/src/):
· tags.rs — TY_IND, TERM_DIMEXPR/CTOR/INDELIM, VAL_VCTOR/VDIMEXPR,
NEU_NINDELIM tag constants per docs/INDUCTIVE_TYPES.md §6.
· value.rs — mk_vctor, mk_vdimexpr, mk_nindelim builders.
· eval.rs — TERM_DIMEXPR / TERM_CTOR / TERM_INDELIM dispatch
arms; full β-reduction on canonical vctor target
(find matching branch by name, vapp chain over
ctor args); stuck nIndElim build for vneu target;
eval_term_list / eval_branches / find_branch_body
helpers (recursive list walking).
· readback.rs — VAL_VCTOR / VAL_VDIMEXPR readback arms;
readback_val_list, map_readback_branches helpers;
NEU_NINDELIM neutral readback; mk_term_dimexpr,
mk_term_ctor, mk_term_indelim builders.
Tests (CubicalTransport/FFITest.lean): nine new smoke arms exercising
canonical-form eval (zero, succ-of-succ, false, cons-true-nil, base,
loop@r), readback round-trip on succ zero, and indElim β on Bool with
both branch directions. Result: 25/25 smoke + 46/46 properties =
71/71 passing.
Existing tests untouched (constructor tags preserved per REL1 freeze).
Rust ABI version is now de facto v2 (new tags); update the
TOPOLEI_FFI_ABI_VERSION constant in a follow-up commit.
Remaining REL1 work (per task list):
- #4 HasType arms for ctor / indElim
- #8 transport over .ind axioms
- #9 composition over .ind axioms
- Path-ctor boundary firing (REL1.1)
- Recursive-arg IH wiring in indElim β (REL1.1)
- Topolei migration (sibling repo) per docs/INDUCTIVE_TYPES.md §9.1
