Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to This PR adds a new four-GPU production endpoint that is exposed on all host interfaces without an explicit authentication or authorization boundary while retaining host networking, host IPC, GPU access, writable cache access, and root runtime privileges. Mutable image tags and configuration/pinning mismatches also weaken reproducibility and operator control, so the PR is not merge-ready until these deployment and correctness risks are fixed or explicitly accepted by the owner.

Pin the default production image to the qualified digest in every launch surface.
The launcher and both Compose files default to a mutable GHCR tag, so a restart or fresh deployment can consume different runtime bytes without a repository change. Replace the defaults with ghcr.io/local-inference-lab/glm53-flash-nvfp4-jovian@sha256:8e621a7e381f46a56ece6e6b794a38fc5f0ddf18c7d1d507d54267367c02699d and require digest-form overrides for production deployments.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use MAX_NUM_BATCHED_TOKENS for this environment value.
The launcher reads MAX_NUM_BATCHED_TOKENS, but this file reads MAX_BATCHED_TOKENS. If an operator sets MAX_NUM_BATCHED_TOKENS=8192, the service still receives 4096.
Proposed fix
- MAX_NUM_BATCHED_TOKENS: ${MAX_BATCHED_TOKENS:-4096}
+ MAX_NUM_BATCHED_TOKENS: ${MAX_NUM_BATCHED_TOKENS:-4096}📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Make B12X_RUNTIME_COMMIT control the installed B12X revision.
The runtime Dockerfile preserves B12X from the head image. It never checks out B12X_RUNTIME_COMMIT. If a caller changes this variable, the image label and cache fingerprint report the new revision, but Python imports the inherited old revision.

Security Misconfiguration (CWE-250)
Reachability: External · Exploitability: Difficult
Run the final service as a non-root user.
The final image runs as UID 0 because Config.User is unset, and the Compose service has no user override. The service binds vLLM to 0.0.0.0 and mounts /cache as writable. A command-execution flaw can therefore create root-owned files in /cache.
Create an unprivileged runtime user, grant it access only to required writable paths, and set USER after the build steps.
