- AST: Def::Type mit Ctors; Term::Ctor (Konstruktion) und Term::Match
mit Arm/Pattern. Patterns: Wild, Var, Lit, Ctor { ctor, fields } —
Sub-Patterns im MVP auf Var/Wild beschränkt.
- Typchecker: Type-Registry, ctor_index für O(1)-Resolution, Pattern-
Bindings, Exhaustiveness-Check gegen volle Konstruktormenge plus
Negativ-Tests.
- Codegen: Boxed-Heap-Layout via malloc; Tag in Offset 0, Felder ab
Offset 8 in 8-Byte-Slots. Match lowert zu load tag + switch + Phi
am Join. Default-Block ist unreachable, wenn vom Typchecker geprüft.
- examples/list.ail.json: rekursive Int-Liste mit sum_list via match.
E2E-Test + Exhaustiveness-Tests. 19/19 Tests grün.
