- Zig L1: Implemented qvl_issue_slash_signal (constructs SlashSignal)
- Rust L2: Added FFI binding and safe wrapper issue_slash_signal
- Config: Wired l1_slash_mod into qvl_ffi build
- Verified: Unit test for signal creation passing
The active defense loop is closed. L2 can now pull the trigger.
- Created qvl_ffi.zig: C ABI exports (qvl_init, qvl_deinit, trust scoring, PoP verification, betrayal detection, graph mutations)
- Created qvl.h: C header with full API documentation
- Created test_qvl_ffi.c: C test harness (manual compilation)
- Added FFI tests to build.zig with libc linking
- Fixed API mismatches: TrustGraph.init (3 args), BellmanFordResult.betrayal_cycles usage
- All tests passing (173/173: 137 SDK + 36 FFI)
FFI enables Rust Membrane Agents (L2) to consume L1 trust functions.
