update-vllm-3090-configs	Update only the qwen3.6-27b vLLM 3090 llama-swap configs from club-3090 refs; compare diffs, present a plan, and require approval before editing.

Update vLLM 3090 Configs

Scope

Use only for Qwen3.6 27B vLLM 3090 configs in modules/nixos/services/llama-swap/. Do not use this skill for other models, other Qwen sizes, non-vLLM configs, or package bumps.

Local files:

• modules/nixos/services/llama-swap/config.nix
• modules/nixos/services/llama-swap/setup-qwen36-vllm.sh

Local config keys:

• vllm-qwen3.6-27b-tools-text
• vllm-qwen3.6-27b-long-text
• vllm-qwen3.6-27b-long-vision

Upstream References

Compare against club-3090 master:

• models/qwen3.6-27b/vllm/compose/single/tools-text.yml
• models/qwen3.6-27b/vllm/compose/single/long-text.yml
• models/qwen3.6-27b/vllm/compose/single/long-vision.yml
• scripts/setup.sh for the current GENESIS_PIN="${GENESIS_PIN:-...}"

Use raw URLs or a temp clone under _scratch/club-3090. Prefer a temp clone when checking broad changes:

mkdir -p _scratch
git clone https://github.com/noonghunna/club-3090 _scratch/club-3090 2>/dev/null || git -C _scratch/club-3090 pull --ff-only

Required Workflow

1. Fetch/update upstream refs under _scratch/club-3090 or fetch the raw files.
2. Compare upstream compose files to the three local llama-swap entries. Translate docker-compose semantics into the existing docker run/llama-swap format.
3. Compare upstream scripts/setup.sh Genesis pin to local GENESIS_PIN in setup-qwen36-vllm.sh.
4. Check upstream compose volumes/entrypoint for sidecar patches. If patches are added, removed, renamed, or invoked differently, update both:
   • runtime mounts and python3 /patches/... calls in config.nix
   • download/install logic and summary in setup-qwen36-vllm.sh
5. Ignore these diffs unless the user explicitly asks otherwise:
   • shm_size / shm-related compose settings
   • local timing patch patch_timings_07351e088.py and its mount/invocation
   • model served-name differences caused by llama-swap ${MODEL_ID}
   • HUGGING_FACE_HUB_TOKEN; keep local CUDA device/env choices
   • upstream relative paths vs local /mnt/ssd/vLLM/... paths
   • docker-compose format vs local llama-swap/Nix format
6. Before editing, present:
   • upstream files/commit checked
   • meaningful diffs found
   • ignored diffs
   • exact planned local changes Then wait for explicit user approval.
7. After approval, edit minimally and validate:
   • bash -n modules/nixos/services/llama-swap/setup-qwen36-vllm.sh
   • nix-instantiate --parse modules/nixos/services/llama-swap/config.nix
8. Summarize changed files and any remaining upstream differences.
