- New generator: compiler/src/generators/z3.ts (1,034 lines) - Translates SpeckDL state → Z3 sort declarations - Translates invariants → Z3 define-fun returning Bool - Translates actions → Z3 transition predicates (enabled + step) - BMC unrolling with --verify-depth=N (default: 10) - CLI: --target=z3 or --target=all - ToggleSwitch and TigerBeetleLedger generate valid SMT-LIB2 - KafkaKRaft spec generates valid SMT-LIB2 structure - Complex forall/set expressions emit 'true' as placeholders (to be improved) - All 41 existing tests still pass This unblocks M1.2 (KRaft verification), M3.2 (Show HN), and M4.3 (OAuth verification).
