Place the imported control label inside a valid multi-byte NOP instead of suppressing Mach-O function-start metadata. Encode the supported ARM64 and x86-64 instructions explicitly and retain the load dependency so the control remains past the function entry. Assert that Ghidra imports a label and no procedure at the control address before checking name rejection and address containment.
Two real arm64 Ghidra 12.1.4 imports confirmed both fixture strategies produce labels; only default linking retains LC_FUNCTION_STARTS. The full native-value CLI/MCP verifier passed with 349 successful and 52 expected rejected boundary calls, including imported aliases, complete exports, and startup cancellation cleanup. Host ARM64 and Apple x86-64 fixture compilation passed; x86 provider execution remains unverified.
* fix(test): preserve Ghidra interior-label controls on Mach-O
* test: preserve selector semantics and accept signaled fixture exits
* test(javascript): exercise deep returns through the public CLI
