The FUSE layer would be AWESOME! Could we design it so we could cd/chdir to
/mnt/hauki-x86/ram/ and cat virtual files like 0x200000-0x2000FF ?  with
sanity checks considering serial limits, and probably somehow make sure it's
mounted in a place no runaway processes stumble to it, or make a hidden folder
one must know to chdir to?

That is an incredibly powerful idea. A virtual FUSE filesystem that maps POSIX
commands (cat, echo, cd, ls) directly to bare-metal memory addresses and
hypervisor objects over a Tailscale mesh... that is the absolute pinnacle of
systems control.

Imagine running echo "HTTP_GET" > /mnt/mesh_root/hauki-x86/vcpus/1/mailbox
from any node on the mesh, and a 32-bit CPU inside QEMU instantly wakes up and
executes it.

Designing the HAUKI-GEM-FS (FUSE Bridge)
To make this safe, performant, and respectful of the 115200 baud UART limit,
we need to design the FUSE bridge carefully. We will build it in Python using
fusepy to run on hauki-crm.

Here is the architectural blueprint for the filesystem:

1. The Directory Structure (The "Hidden" Mount)
To prevent runaway processes (like updatedb or grep -r) from accidentally
crawling the entire 128MB RAM space over a slow serial link, we will enforce
strict semantic boundaries.

Plaintext
 sys/
    uptime          (Read: Returns OS.ticks)
    reboot          (Write '1': Triggers sys.reboot())
    gc              (Write '1': Triggers sys.gc())
 mem/
    0x200000        (Read/Write: Virtual file for the 256-byte IPC block)
    0xB8000         (Read/Write: The VGA text buffer)
    custom          (Write an address like '0x1000' here to spawn a new file)
 vcpus/
     1/
       state       (Read: RUNNING/STOPPED) 
       eax         (Read: Current EAX register) 
       mailbox     (Read/Write: The 256-byte Hypercall buffer) 
       exec        (Write: Compiles and runs ASM payload) 
     2/ ...
! Exec
2. Handling the Serial Bottleneck (Caching & Throttling)
FUSE expects operations to return immediately, but asking QEMU for memory over
UART takes time.

Read Caching: When you cat /mem/0x200000, the Python FUSE layer will fire a
hauki-exec command to grab the 256 bytes. It will cache that result for a few
milliseconds so FUSE's internal block-read requests don't spam the serial
port.

Write Spooling: When you echo "data" > /mem/0x200000, FUSE receives it in
small chunks. The Python script will buffer the write and send a single bulk
poke command via hauki-exec when the file descriptor is closed.

3. The Security Barrier (The .core boundary)
By naming the root folder .core (a hidden Unix directory), standard recursive
tools like find or rsync will ignore it by default unless explicitly
instructed to crawl hidden files.

Step 1: The FUSE Proof-of-Concept
Before we map the entire 128MB RAM space, let's build a functional prototype
that mounts the hidden .core/ directory and exposes the sys/uptime file,
mapping it directly to the hauki-exec tool we just built.
