+**Junk opcodes:** The compiler inserts random junk opcodes (0x1C-0x1F) at ~33% probability between real instructions. The VM silently consumes them via the `default` case, breaking linear disassembly. Use `CompileWith(program, CompileOpts{NoJunk: true})` for deterministic output.
+
+### 10. Anti-Disassembly Injection
+
+Injects junk `[N]byte` variable declarations at ~15% per statement to confuse disassemblers and decompilers.
+
+```go
+// Injected junk — valid Go, but semantically dead
+var _j1 = [7]byte{0x4e, 0x6f, 0x70, 0x65, 0x21, 0x00, 0x00}
+var _j2 = [12]byte{0xde, 0xad, 0xbe, 0xef, ...}
+```
+
+These produce opaque byte sequences in the binary that disassemblers cannot reliably skip.
+
+### 11. Junk String Injection
+
+Adds 4-10 fake string constants per file to dilute the `strings` output and increase noise for analysts.
+
+```go
+var _js1 = "xK9mP2vL8nQ4wR7yT"
+var _js2 = "aB3cD5eF7gH9iJ1kL"
+```
+
+These strings have no semantic effect but increase the string table from ~200 to ~4000+ entries, making secret extraction harder.
+
+### 12. Function Pointer Dispatch
+
+Wraps function calls through function pointer variables to obscure call targets.
+
+```go
+var _fptr0 = checkLicense_obf4721  // function pointer variable
+//go:noinline
+func checkLicense(args ...interface{}) interface{} {

 ## Limitations
 
 - **Text-based transformation:** The transformer operates on source text, not Go AST. This limits what can be reliably transformed (e.g., type inference for variable hoisting is heuristic).
-- **Darwin syscall stubs:** `pkg/syscallobf` returns `ENOSYS` on macOS. Linux is the primary target for runtime protections.
 - **Garble required:** Stage 2 depends on `mvdan.cc/garble` for name mangling, literal encryption, and binary stripping.
 - **Simple function virtualization only:** The VM currently handles len-comparisons and arithmetic. Complex control flow is not virtualized.
+- **Windows integrity check:** PE `.text` section hashing works but is less battle-tested than ELF/Mach-O paths.
