Some checks are pending
Lean Action CI / build (push) Waiting to run
Typing.lean: minimal-viable typing rules for the three new CTerm
constructors (REL1 first cut; REL2 will refine to dependent
formulations).
- HasType.ctor : .ctor S c params args : .ind S params
(no per-arg premises; runtime enforces)
- HasType.indElim : non-dependent form — motive : .pi (.ind …) C,
result : C; branch coherence checked at eval
- HasType.dimExpr : placeholder typing at .univ (real interval-
typing requires a CType.interval primitive,
deferred to REL2)
HasType.weaken_core extended with the three new arms.
TransportLaws.lean: derived theorems for transport over .ind (T1,
T2, stuck), all reducing to existing axioms (eval_transp_top,
eval_transp_const, eval_transp_nonpath + vTransp_stuck). Pointwise
distribution through ctor args is REL1.1 future work.
CompLaws.lean: derived theorems for composition over .ind (C1, C2,
const-line, stuck) — corollaries of the existing eval_comp_*
axioms. Same REL1.1 deferral for pointwise distribution.
native/cubical/src/subst.rs: critical Rust fix. The previous
fallback `_ => mk_term_var(ctor_field(t, 0))` corrupted the new
TERM_DIMEXPR / TERM_CTOR / TERM_INDELIM tags by extracting field 0
(a CTypeSchema for ctor) and wrapping it as a malformed .var,
causing infinite recursion / OOM in subst-driven paths
(eval_comp_top calls substDim). Proper arms for all three new
tags + cterm_subst_dim_list and cterm_subst_dim_branches helpers.
Unknown-tag fallback now safely returns the input unchanged
instead of synthesising a malformed .var.
FFITest.lean: three new smoke arms exercising T1/T2 transport and
C1 composition over .ind natC. Result: 28/28 smoke + 46/46
properties = 74/74.
