That is a beautiful sight. The test runner orchestrated the boot sequence,
connected via TCP, processed the inbound stream through the VFS-loaded
bytecode, routed the ECALL, executed the net_write syscall, and cleanly
asserted the results.
Your V1.0 microkernel now has a fully automated integration pipeline. You can
refactor the core engine with absolute confidence, knowing that if you break
the memory model or the execution loop, this test suite will instantly catch
it.
Let's update the Master Control Room AST-MD to reflect this victory.

Next Objective: Modular Efuns (ROADMAP_MODULAR_EFUNS)
Right now, system calls like write, read_mail, and net_write are hardcoded
directly into the Compiler and manually injected into the vm.ivt array during
the boot sequence. To build a true "mudlib", we need a pluggable architecture
where dropping a new JavaScript file into an efuns/ directory automatically
makes it available to the LPC environment.
Here is the precise prompt to feed into a new dev-chat to architect this
dynamic auto-loader.
Prompt for Dev-Chat:
> System Prompt:
> You are an expert systems engineer working on the HAUKI-X86 LPC Engine.
> Rule 1: You must strictly obey the architectural boundaries defined in our
AST-MD documentation.
> Rule 2: Absolutely no source code file you generate may exceed 150 lines in
length.
> Rule 3: The VM execution core remains strictly isolated.
> Current Task:
> We are implementing ROADMAP_MODULAR_EFUNS. We must decouple hardcoded system
calls from the Compiler and LPCVirtualMachine.
> Requirements:
> 1. src/system/EfunManager.js
>  * Create a class that loads standard Node.js modules from a new src/efuns/
directory.
>  * It must populate a given vm.ivt array using the IDs specified in the efun
modules.
>  * It must generate a syscallMap (e.g., { 'write': 1, 'net_write': 30 }).
> 2. Refactor src/compiler/compiler.js
>  * The Compiler constructor should now accept an optional syscallMap
parameter alongside the vfs.
>  * Replace the hardcoded CallExpression identifier checks (e.g., if
(node.callee.name === 'write')) with a dynamic lookup against this.syscallMap.
>  * If the node.callee.name exists in the map, compile the arguments and emit
the SYSCALL opcode using the mapped ID. (Remember: R1, R2, R3 are the ABI
registers for arguments).
> 3. Example Efun Module (src/efuns/sys_write.js)
>  * Write a sample module exporting the write efun so we can see the expected
format. It should export name, id (1), and the handler function.
> Please generate EfunManager.js, the refactored compiler.js, and the sample
sys_write.js. Ensure no file exceeds 150 lines.
