-`<repo>/models-cache/` by default. Override with `MODEL_DIR=/path/to/your/scratch bash scripts/setup.sh qwen3.6-27b`. See [`.env.example`](../.env.example) for all env vars.
+Yes. The knob is `MODEL_DIR`, with **four ways** to set it (priority order):
+
+1. **`MODEL_DIR` env var in your shell** — takes precedence over everything:
+   ```bash
+   export MODEL_DIR=/mnt/your-second-drive/models
+   bash scripts/setup.sh qwen3.6-27b
+   ```
+2. **`.env` file at repo root** — picked up automatically on every script run. See [`.env.example`](../.env.example).
+3. **Interactive prompt** — `bash scripts/setup.sh qwen3.6-27b` with nothing set offers three choices: in-repo default, `~/models`, or custom path. After you pick custom, it asks "Save `MODEL_DIR=/your/path` to `.env` so we skip this next time?" — say `Y` and it persists for every subsequent `launch.sh` / `switch.sh` / `bench.sh` call.
+4. **Silent fallback** — `<repo>/models-cache/`. Functional but pollutes the git tree; not recommended.
+
+Every script that touches model paths reads from the same `MODEL_DIR`. The compose YAMLs' volume mount is `${MODEL_DIR:-...}:/root/.cache/huggingface` — once set, every container reads + writes there.
+
+**HF env-var integration** — we don't directly respect `HF_HOME` / `HF_HUB_CACHE` because we mount a host directory INTO the container's `/root/.cache/huggingface`, not the host's HF cache. The internal layout inside `MODEL_DIR` matches HF's repo-cache convention (`<MODEL_DIR>/<repo-subdir>/`), so models downloaded by `setup.sh` are byte-compatible with anything that reads HF's local cache layout. Two clean workarounds if you already have an HF cache you want to reuse:
+- Set `MODEL_DIR=$HF_HOME/hub`
+- Or symlink between them
+
+**On Windows / WSL2** — same mechanism. Docker Desktop handles path translation. Use Windows paths (`D:\models`) from PowerShell or WSL paths (`/mnt/d/models`) from WSL. If you flip between Linux and Windows on the same rig, point `MODEL_DIR` at a drive both OSes can see — the model files themselves are OS-agnostic.

 ### How do I keep my install up-to-date?

@@ -33,6 +33,22 @@ The recipes are written against 3090 specifically but should work on:

 **Won't work:** anything with <20 GB VRAM (3060, 3070, stock 3080, 3080 Ti). The 27B model in INT4 is ~18 GB — KV pool + activations push past 24 GB on smaller cards even with aggressive quantization. **Modded 20 GB 3080s do work** (see row above) — the mod gives them enough headroom for the 27B + TQ K8V4 KV path on TP=2, with `mem-util=0.82` to absorb cudagraph profiling overhead.

+### Mismatched / heterogeneous GPUs
+
+`scripts/switch.sh` reads hardware metadata from the vLLM compose headers before starting Docker. The preflight checks required GPU count, per-GPU VRAM, tensor parallel size, and any hard SM floor.
+
+For TP=1 vLLM composes, `switch.sh` auto-selects the largest eligible GPU and exports it through `NVIDIA_VISIBLE_DEVICES`. On a mixed 16 GB + 24 GB rig, `bash scripts/switch.sh vllm/default` should pick the 24 GB card instead of trying to boot on GPU 0 blindly.
+
+Overrides:
+
+```bash
+CLUB3090_GPU=1 bash scripts/switch.sh vllm/default
+NVIDIA_VISIBLE_DEVICES=2,3 bash scripts/switch.sh vllm/dual
+bash scripts/switch.sh --force vllm/gemma-mtp-tp1
+```
+
+Use `--force` only when you are intentionally testing an unsupported combo. Example: `vllm/gemma-mtp-tp1` is now preflight-blocked on a 24 GB 3090 because the compose is preserved for 32 GB / newer-SM single-card rigs.
+
 ### Note for sub-24 GB cards

 On 20 GB cards (modded 3080) the cudagraph-profiling overhead is a meaningful slice of available VRAM. Drop `--gpu-memory-utilization` to **0.82** (vs shipped 0.95 for 24 GB). vLLM nightly's `gpu_worker.py` reports the equivalent effective KV size in the boot log; tune to keep activation headroom for the ~15K tool-prefill peak (verify-full check 8).

+
+## Installation: sidecar pattern (v0.5.1+)
+
+The overlay is **not** mounted directly at vLLM's site-packages paths. Instead:
+
+1. Both files are bind-mounted at side paths under `/etc/club3090/`:
+   - `pr35936-chat-completion-serving.py`
+   - `pr35936-engine-serving.py`
+2. `install.sh` is bind-mounted at `/etc/club3090/install-pr35936.sh`
+3. The compose entrypoint invokes `bash /etc/club3090/install-pr35936.sh`
+   **before** any other patch step (`python3 -m vllm._genesis.patches.apply_all`
+   in Genesis-loaded composes, or `exec vllm serve` in Genesis-less ones).
+4. `install.sh` copies our files into vLLM's site-packages with `cp`. The
+   destination becomes a writable file in the container's RW layer.
+
+### Why a sidecar instead of an RO bind-mount
+
+v0.5.0 originally mounted both files directly at vLLM's site-packages paths
+with `:ro`. That broke 8 Genesis-loaded composes because Genesis P64
+(qwen3coder MTP streaming early-return), P68 (auto force tool_choice=required),
+and P69 (long-context tool-format reminder) all write hooks into
+`chat_completion/serving.py` at vllm-import time. The RO mount blocked those
+writes with `Errno 30: Read-only file system`, and Genesis explicitly warned
+"partial state risk; container should be torn down." Reported by @ygafarov in
+[#120](https://github.com/noonghunna/club-3090/issues/120#issuecomment-4443236686);
+sidecar pattern shipped in v0.5.1.
+
+The sidecar resolves it cleanly:
+- Our patched files land in the container's RW layer (not bind-mounted RO)
+- Genesis can write its hooks on top freely
+- Host patches dir stays canonical (no Genesis hooks bleeding into our git tree)
+- Each container restart starts fresh; Genesis re-applies on a clean copy
+
+If a future patch to our overlay also touches `chat_completion/serving.py`
+(e.g. when PR #35936's streaming hunks land for a nightly we pin to), the
+sidecar layout supports it without further changes — our patched content
+sits on disk in the install.sh source path, gets installed before Genesis
+runs, Genesis layers its hooks on top.

+# Install PR #35936 required-tool fallback overlay into vLLM's site-packages.
+#
+# WHY a sidecar instead of an RO bind-mount:
+# Genesis P64 (qwen3coder MTP streaming early-return), P68 (auto-force
+# tool_choice=required), and P69 (long-context tool-format reminder) all
+# write hooks INTO chat_completion/serving.py at vllm-import time. An RO
+# bind-mount blocks those writes with `Errno 30: Read-only file system`,
+# and Genesis explicitly warns "partial state risk; container should be
+# torn down."
+#
+# Sidecar copies our files into the container's RW layer BEFORE Genesis
+# runs, so Genesis can write its hooks freely on top. Same pattern we
+# used for `patch_tolist_cudagraph.py` before Genesis absorbed it.
+#
+# Today chat_completion/serving.py is byte-identical to the upstream
+# nightly (PR #35936's streaming hunks don't apply on our pin), so
+# Genesis writes its hooks onto a clean copy. Slot stays future-ready
+# for when streaming hunks land — our changes will sit underneath
+# Genesis writes.
+#
+# Idempotent: cp overwrites unconditionally (per-boot fresh copy is
+# correct behaviour — Genesis re-applies on each fresh container).

noonghunnaandClaude Opus 4.7	6617e1e090	fix(qwen): PR #35936 overlay — sidecar pattern to resolve Genesis RO-mount conflict Release / release (push) Failing after 52s Details v0.5.0 mounted vLLM PR #35936 overlay files as :ro bind-mounts at vLLM's site-packages paths. On Genesis-loaded composes, this blocked Genesis P64 (qwen3coder MTP streaming early-return), P68 (auto force tool_choice= required), and P69 (long-context tool-format reminder) — all three write hooks into chat_completion/serving.py at vllm-import time. Genesis reported "Errno 30: Read-only file system" and warned "partial state risk; container should be torn down." Reported by @ygafarov on club-3090#120: https://github.com/noonghunna/club-3090/issues/120#issuecomment-4443236686 This commit converts all 23 PR #35936-mounted composes to a sidecar pattern: 1. Patched files are bind-mounted at side paths under /etc/club3090/ (pr35936-chat-completion-serving.py, pr35936-engine-serving.py). 2. install.sh is bind-mounted at /etc/club3090/install-pr35936.sh. 3. Each compose entrypoint invokes `bash /etc/club3090/install-pr35936.sh` BEFORE Genesis runs (apply_all in Genesis-loaded composes, or vllm serve invocation in Genesis-less ones). 4. install.sh copies the files into vLLM's site-packages via `cp`, landing them in the container's RW layer. Result: Genesis can write its hooks freely on top of our content. No RO-mount errors. Host patches dir stays canonical. Three entrypoint variants handled: - A) Existing apply_all invocation (9 composes — Genesis-loaded): insert install.sh before `python3 -m vllm._genesis.patches.apply_all` - B) Simple `exec vllm serve` (13 composes — non-Genesis): prepend install.sh before exec - C) No entrypoint at all (1 compose — qwopus): add new entrypoint that runs install.sh then exec's vllm serve Validated 2026-05-13 on single/long-text.yml (Genesis-loaded): [club3090/pr35936] chat_completion/serving.py installed from /etc/club3090/... [INFO:genesis.apply_all] applied: P64 qwen3coder MTP streaming early-return fix — P64 applied: 2 files modified, 0 idempotent [INFO:genesis.apply_all] applied: P68/P69 long-context tool-call adherence — Hook injected into create_chat_completion Zero `Read-only file system` errors anywhere in boot log. Pattern is forward-compatible: if a future PR #35936 patch update touches chat_completion/serving.py (e.g. streaming hunks), the sidecar layout already supports layering our content under Genesis writes — no further plumbing changes needed.

noonghunnaandClaude Opus 4.7	1678ca0c8b	docs: clarify MODEL_DIR — second drive / HF cache / Windows-WSL @tomByrer asked on disc #125 about pointing the scripts at a model dir on a second drive. The support has always been there (MODEL_DIR env var with 4-tier resolution: shell export, .env file, interactive prompt, silent fallback) but the docs were too terse to discover without running setup.sh interactively. Two changes: - docs/FAQ.md: expand the "where does it go?" entry from a one-liner to a full explanation covering all 4 resolution paths, HF env-var integration (we mount host dir INTO container cache, so HF_HOME isn't directly respected but layout is byte-compatible), and Windows/WSL2 path handling. - README.md: add a 3-line parenthetical to step 2 of the quickstart pointing at MODEL_DIR. Users who copy-paste the quickstart now see the option without having to dig. Both surfaces now point at the same canonical answer.

noonghunnaandClaude Opus 4.7	14ffe45667	docs(upstream): correct stale vllm#40807 row + add #40798/#42215 row The UPSTREAM.md row for vllm#40807 (.tolist cudagraph crash) and the P78 comment in tq3-mtp-genesis.yml both claimed we ship a local patch_tolist_cudagraph.py sidecar. That sidecar was retired on 2026-05-05 when we bumped Genesis to v7.72.2 (which provides P78 as the equivalent guard) — but the docs never caught up. Two stale lines fixed: - docs/UPSTREAM.md vllm#40807 row: was "⚫ Local workaround", now "✅ Retired locally" with the actual current state (P78=0 on tq3-mtp-genesis.yml because rebench-full leg 6 passed clean without it; non-Genesis composes on 1acd67a79 pin run without any guard, unvalidated at long-context TurboQuant chunked-prefill). - tq3-mtp-genesis.yml line 197 comment: was "superseded by our patch_tolist_cudagraph.py" (the file we no longer ship), now explains the actual reason P78=0 (rebench evidence) plus the flip-to-1 trigger. Also adds a new UPSTREAM.md row for vllm#40798 + vllm#42215 — the upstream pair that closes the workspace-locked assertion at turboquant_attn.py:_continuation_prefill for ≥48K-token chunked- prefill with TurboQuant KV. Independently validated on 2× 3090 sm_86 by @cferra (vllm#41403 comment, 2026-05-12). On our stack, Genesis PN34 addresses the same symptom via a different mechanism (relax-lock vs reserve-before-capture); when the upstream pair propagates to a nightly we pin to, we'd A/B PN34 vs the pair.
