- Add __tests__/e2e-wasm.test.ts: full pipeline test
- Parse Counter speck → generate WAT → assemble with wabt → instantiate → run
- Verify init, action calls, guard pass/fail, state mutations
- TigerBeetle WAT validation test (wabt parse + validate + toBinary)
- Fix wasm.ts bugs found by E2E:
- Guard condition inverted: added i32.eqz to negate comparison
- Missing local declarations: locals now inserted before body
- Uncompiled guards left stack values: now emit comments only (no i32.const 1)
- Install wabt npm package for WAT→WASM assembly in tests
- 41/41 tests passing (39 original + 2 E2E)
Milestone: Speckl produces runnable WebAssembly from specs.
