## 3. Managed Assembler (spec: managed-assembler)
- [ ] 3.1 Add tests for `EmitU8`/`EmitU32`/`EmitU64` little-endian primitives
- [ ] 3.2 Implement `WhiteMagic/Assembly/StubAssembler.cs` emitters + `IAssembler` interface to pass 3.1
- [ ] 3.3 Add tests for x86 cdecl stub encoding (reverse push, call, `add esp, N*4`, ret) with known byte expectations
- [ ] 3.4 Implement x86 cdecl stub to pass 3.3
- [ ] 3.5 Add tests for stdcall (no caller cleanup), thiscall (ecx = this), fastcall (ecx/edx) x86 stubs
- [ ] 3.6 Implement x86 stdcall/thiscall/fastcall stubs to pass 3.5
- [ ] 3.7 Add tests for x64 stub argument-register placement and call
- [ ] 3.8 Implement x64 stub to pass 3.7
- [ ] 3.9 Confirm no FASM/`ManagedFasm` reference exists in `WhiteMagic` output (assert via a test that scans loaded references)
- [x] 3.1 Add tests for `EmitU8`/`EmitU32`/`EmitU64` little-endian primitives
- [x] 3.2 Implement `WhiteMagic/Assembly/StubAssembler.cs` emitters + `IAssembler` interface to pass 3.1
- [x] 3.3 Add tests for x86 cdecl stub encoding (reverse push, call, `add esp, N*4`, ret) with known byte expectations
- [x] 3.4 Implement x86 cdecl stub to pass 3.3
- [x] 3.5 Add tests for stdcall (no caller cleanup), thiscall (ecx = this), fastcall (ecx/edx) x86 stubs
- [x] 3.6 Implement x86 stdcall/thiscall/fastcall stubs to pass 3.5
- [x] 3.7 Add tests for x64 stub argument-register placement and call. Now also asserts Microsoft x64 ABI compliance: `sub rsp, 0x20` shadow-space allocation (stack args land at `[rsp + 0x20 + 8*(i-4)]`), 16-byte stack alignment at the inner `call target`, `mov r64, imm64` loads for RCX/RDX/R8/R9 with the full 64-bit immediate (regression test for the old `mov r32d, imm32` truncation bug).
- [x] 3.8 Implement x64 stub to pass 3.7. Builds a compliant Microsoft x64 ABI frame: `sub rsp, 0x20`, 64-bit register loads, stack-argv above the shadow window, `call rel32`, `add rsp, 0x20`, `ret`. Accepts `nuint[]` so callers can pass full 64-bit pointers unchanged (x86 path truncates `nuint` → `uint` with a range check).
- [x] 3.9 Confirm no FASM/`ManagedFasm` reference exists in `WhiteMagic` output (assert via a test that scans loaded references)
## 4. Crash-Safe Execution Slice (spec: remote-execution, function-hooking)
