c2a7b78f6b* Studio: exclude mlx-lm 0.31.3 (broke gemma4/qwen3_5 QK-norm load) mlx-lm 0.31.3 regressed the QK-norm archs: its strict load_weights rejects the q_norm/k_norm tensors with "Received N parameters not in model", so gemma4 and qwen3_5 checkpoints fail to load. Studio installs the MLX stack unpinned at latest, which pulls 0.31.3. Verified on a real macos-14 runner: gemma4 fails to load on 0.31.3 but loads and generates coherently on 0.31.2 and on git-main (future 0.31.4). See mlx-lm #1242. Exclude just that release (!=0.31.3) in the installer and the self-heal floor so --upgrade still resolves to the newest good build, and treat an already-installed 0.31.3 as unsatisfied so the self-heal replaces it. * Studio MLX: cover fresh-install path + robust bad-version compare Address PR review: - Fresh install.sh (Apple Silicon) runs the base 'uv pip install unsloth' with SKIP_STUDIO_BASE=1, skipping the guarded MLX-stack step, so transitive resolution could still pull mlx-lm 0.31.3. install.sh already exports UV_OVERRIDE -> overrides-darwin-arm64.txt before that install, so exclude mlx-lm 0.31.3 there too; this also strengthens the self-heal (same override). - Match the known-bad version with parsed packaging.Version so 0.31.3 == 0.31.3.0 (trailing-zero normalization) instead of raw string equality. * Studio: exclude mlx-lm 0.31.3 on the fresh Apple Silicon install too The overrides file only applies via UV_OVERRIDE when it exists relative to the script, which is not true for a curl-piped install, and the guarded MLX step in install_python_stack.py is skipped there (SKIP_STUDIO_BASE=1). So the base install could still resolve the transitive mlx-lm to the broken 0.31.3. Append mlx-lm!=0.31.3 to the base install on Apple Silicon (empty elsewhere), so the fresh path pins away from 0.31.3 without waiting for the runtime self-heal. * Studio: exclude mlx-lm 0.31.3 on the migrated install; keep the >=0.22.0 floor The with-deps migrated install did not append ${_MLX_LM_EXCLUDE_ARG:-}, so a curl-piped Apple Silicon migration (no repo overrides file, UV_OVERRIDE unset) could resolve mlx-lm 0.31.3 transitively. Append the exclusion there, matching the fresh install path. The no-torch migration is left alone since --no-deps never resolves mlx-lm (same as the fresh no-torch path). Also restore the >=0.22.0 floor in overrides-darwin-arm64.txt: a uv override replaces the transitive constraint, so a bare !=0.31.3 could let the resolver drop below the supported minimum that mlx_repair.py enforces at runtime. * Triage huggingface_hub 1.22.0 / fastapi / multiprocess scanner false positives The scan-packages gate red-failed on all three shards after transitive deps bumped. Every new CRITICAL is a benign false positive, verified against upstream: - huggingface_hub 1.22.0 added _sandbox.py for the remote HF sandbox feature. Its job-startup bootstrap string (fetch sbx-server into the container /tmp and exec it) and the SandboxPool host-reservation loop trip the staged-dropper and C2-loop heuristics; that script runs inside a remote HF container, not on the user machine. The bump also re-hashed the already-reviewed benign polling loops in hf_api.py and utils/_http.py. The PyPI artifact is byte-identical to the official v1.22.0 tag. - fastapi 0.139.0 routing.py re-hashed the websocket keepalive while-True loop; byte-identical to upstream 0.139.0. - multiprocess 0.70.19 forkserver.py and tests/__init__.py re-hashed the AF_UNIX fork-server IPC and fd-inheritance tests; genuine uqfoundation release, local IPC not network. Added 7 reviewed allowlist entries (no blind regenerate). All three shards (hf-stack, studio, extras) exit 0 locally. * Tighten mlx-lm 0.31.3 exclusion comments * Trim mlx-lm 0.31.3 exclusion comments
