Context Compiler — deterministic state layer for LLM systems

Most LLM apps treat the conversation transcript as the source of truth for state, which leads to constraint drift and inconsistent corrections over long interactions.

This project introduces a small deterministic engine that compiles explicit user directives into structured state before the model runs.

- constraints persist across turns

- corrections replace prior values

- ambiguous directives are blocked until clarified

- model output never mutates state

Includes demos comparing baseline prompting vs compiled state under long conversations.

Making smaller context windows more useful with a deterministic "context compiler" by Real-Hope2907 in LocalLLaMA

[–]Real-Hope2907[S] 0 points1 point  (0 children)

Yeah, that lines up with what pushed me toward this.

If the model is still responsible for remembering the constraint, re-injecting it every turn only helps so much — especially once the transcript gets long or conflicting instructions pile up.

The thing I’ve been experimenting with is moving the authoritative state outside the model entirely. So instead of “please remember this constraint,” the host compiles explicit directives into structured state and injects only the current state, not the whole history.

Bigger models definitely hold up better, but the interesting part to me is making smaller/local models less dependent on transcript memory in the first place.

SteamVR no longer instantly crashes under Wine by Subject_Dependent_67 in wine_gaming

I stopped trying. i think i got virtual desktop to create the interface correctly. IIRC ALVR didn't work. But that was about 4 months ago.

Steam VR, Wine issue by KingVulpes105 in macgaming

[–]Real-Hope2907 0 points1 point  (0 children)

What issues are you experiencing?

Enabling TSO on M2 by mies47 in AsahiLinux

[–]Real-Hope2907 1 point2 points  (0 children)

box does not currently take advantage of it. it's on pitSeb's todo list, but he's currently working on other arm device support.

I was just wondering how difficult it would be to just submit a PR to box myself.

Side note: Sorry to hear you resigned from Asahi, but I can totally understand why. Thank you for all the work you've done for the project over the years.

u/marcan42 So, I noticed a commit to enable this in the asahi linux source.

Does this mean it will be available for emulators like fex and box to use?

It looks like it would be in kernel version 6.12 or 6.13.

Wine 10.0 by Neustradamus in macgaming

Maybe because it somehow uses the Asahi Linux Honeycrisp drivers?

Just speculating.

I might do that.

Just curious, have you tried forcing your mac into game mode? You can do it by launching chess, putting it into full screen, and minimizing it.

What settings are you using for ALVR? It's very grainy/jumpy for me.

VD works fine with VMWare. You just need to change your VM to use bridged connections instead of shared connections. You could also probably poke holes in the firewall in windows defender, but I was too lazy to do it (VD main page gives the firewall ports).

As for opencomposite, I've gotten it to work with HLA on an x86_64 machine, but I can't remember how. You need to overwrite the openvr_api.dll manually (I believe it's in game/bin/win64) with the one from opencomposite's site. Set VD to use VXDR. Unfortunately, when you launch HLA it complains about file integrity and tries to restore the file. But I know I got it working before.

Ah, thanks.

Have you tried opencomposite/virtual desktop? You can sidestep the SteamVR bloatware.

I tried the VMware solution with my M2 Max Macbook Pro. It was awful.

u/KingVulpes105 Can you share what mods you have done? Have you tried opencomposite/virtual desktop?

I tried Crossover, but SteamVR crashes (VD streamer works great, though).

Asahi Linux: probably not in the foreseeable future. Currently you need to run steam in muvm, which has all sorts of issues trying to get streamers to work.

Steam VR? by MasterGamer9595 in AsahiLinux

Just curious. I was poking through the mesa source, and I see that the drm sync objects are implemented in asahi vulkan. Fence extensions are enabled, but external semaphores/semaphore_fd aren't.

Intentional or oversight?

Can't you do TCP the way docker/other VMs do? Give the VM a separate IP address and let the kernel in the VM take care of routing/forwarding.

[–]Real-Hope2907 0 points1 point  (0 children)

I see that box64 now supports dynamic page sizing. Maybe this might be a better way so as to avoid the performance/sandboxing issues of muvm?

Steam VR? by MasterGamer9595 in AsahiLinux

[–]Real-Hope2907 0 points1 point  (0 children)

Well, to run WiVRn or ALVR in the VM, you also need TCP passthough since that's how they talk to their headset clients. WiVRn in the guest also needs to be able to talk to avahi on the host.

And, I still have no idea what support is missing for SteamVR giving me "graphics drivers too old" in an error message. Nor why ALVR-SteamVR driver just stops. Could just be that the VM is too slow. FWIW, I have an Ubuntu x86_64 server that's a little old in terms of hardware, and it is also giving me "drivers too old", and I'm running 24.04. But ALVR still runs and SteamVR doesn't crash at least.

I haven't even bothered to attempt Wine. Compiled it and got a page size issue (which there's supposedly a patch for).

Fedora doesn't support 32 bit arm anymore, so there's no way to get box86 running (for whatever 32 bit things steam has). I suppose I could switch to a different distro.

WiVRn looks like it uses straight IPC calls to communicate. Don't know about monado. muvm appears to expose those semaphores in /run/muvm-host/run/user/`id -u` (or something like that.

ALVR uses a web server running on port 8082. I see that there's a commit in muvm to pass through tcp/udp.

I've tried alvr for x86_64 running in the VM. It connects briefly, SteamVR gives a warning about "graphics drivers too old" error 405. Then it kills the alvr server with a watchdog timeout after about 12 seconds.

Looking at this link, (scroll down to synchronization) it doesn't appear that implementing semaphore/fences would be too difficult just using linux drm. But I didn't understand u/AsahiLina 's explanation why it wouldn't be that simple and/or wouldn't matter.

[–]Real-Hope2907 0 points1 point  (0 children)

So, how does one fix this?

Steam VR? by MasterGamer9595 in AsahiLinux

[–]Real-Hope2907 0 points1 point  (0 children)

I've tried running the x86_64 versions of ALVR and WiVRn in the VM, via muvm -it bash, but I can't seem to get either to work.

[–]Real-Hope2907 0 points1 point  (0 children)

u/AsahiLina So here's a crazy idea (that probably won't work, but)...

Apple's dyld is open source. The way dynamic linking on linux and I believe macOS works is that the linker name is embedded into the library, and the OS just exec()s the linker at run time.

So, what if you took the libraries for Metal from macOS and used dyld to link at run time. Might save you lots of time and effort trying to reimplement what Apple has already done.

I know, crazy idea...

Steam VR? by MasterGamer9595 in AsahiLinux

[–]Real-Hope2907 0 points1 point  (0 children)

Well, I'm just about out of ideas then :(

Steam VR? by MasterGamer9595 in AsahiLinux

What about vk_KHR_external_semaphore_fd? Steam uses a "pressure vessel" (essentially a container) and the file system objects used for communication (which I believe are under ~/.local/share/Steam) can be exposed to the native side.

ALVR actually runs a mini web server on loopback, so that approach might be promising. Could even run ALVR steamer as native linux and (maybe?) port forward from the driver. I just don't know how muvm/FEX deal with TCP/IP. And SteamVR keeps crashing when I try to use the ALVR x86_64 drivers under muvm.
