Floor bumped from `>=0.8.0` to `>=0.21.0` in both the `[vllm]` and `[triattention]` extras in [pyproject.toml](pyproject.toml). **Relevant to our open tracker rows:** (a) **Gemma4 MTP** (#41745) + MTP for MiMo-V2.5 (#41905) + EAGLE for Mistral (#41024) — vLLM gains the MTP heads natively that FU-028 still can't get on the MLX side; (b) **TurboQuant hybrid model + uniform quantization** (#39931) — relevant to FU-001 / cache-strategy CUDA parity; (c) **Spec-dec with thinking budget** (#34668) — reasoning-model spec dec is correct now (Qwen3.5/3.6/R1); (d) **Qwen3.5/Mamba hybrid Model Runner V2** (#35520) — matters for FU-031 + Coder-Next; (e) **Gated DeltaNet attention for Qwen 3.5/3.6** CPU path (#41025). **Breaking build changes upstream** (consumed transparently by us): C++20 required (PyTorch compat) — affects FU-052's Windows test runner toolchain; transformers v4 deprecated → must migrate to transformers v5. We do not exercise vLLM on Apple Silicon so this is a no-op locally; FU-052 vLLM cells against `Qwen/Qwen3-0.6B` + `Qwen/Qwen3.5-4B` should be re-run on the next Windows / Linux CUDA pull to confirm the matrix still passes against the bumped floor. No code changes required; the `[vllm]` extra was the only contract point and it stays loose-bounded (`>=`) so users with newer vLLM are still satisfied. | | ~~FU-059~~ | ~~Nunchaku pin correction: `>=1.2.1` → `>=0.16.0`~~ | **Shipped 2026-05-17.** | The FU-023 pin `nunchaku>=1.2.1` in `_INSTALLABLE_PIP_PACKAGES` ([backend_service/routes/setup/__init__.py:118](backend_service/routes/setup/__init__.py)) was unsatisfiable: `pip index versions nunchaku` returns max `0.16.1` on PyPI (full history `0.1.0 → 0.16.1`, no `1.x` line exists). Either the original FU-023 note had a typo, OR upstream pulled / renumbered the `1.x` release after the FU-023 tracker line was written. The setup-tab "Install Nunchaku" action would have failed with "No matching distribution" for every user running it after the original FU-023 ship. Floor lowered to `>=0.16.0` so the install button actually resolves to PyPI's current 0.16.1 wheel. Comment in [routes/setup/__init__.py](backend_service/routes/setup/__init__.py) updated to reflect the version reset. **What still needs verification:** the FU-023 wrappers in [image_runtime.py](backend_service/image_runtime.py) (`NunchakuFluxTransformer2dModel` / `NunchakuQwenImageTransformer2DModel` / `NunchakuSD3Transformer2DModel` / `NunchakuSanaTransformer2DModel` / `NunchakuPixArtSigmaTransformer2DModel`) need a live CUDA run against `nunchaku==0.16.1` to confirm the class API still matches — the original FU-023 work was tested against the (now non-existent) 1.2.1 surface, so the class names may have moved between versions. Can't validate on this M4 Max box; trip-wire stays open until the FU-056 Windows-runner work picks it up. | | ~~FU-060~~ | ~~Mock memory-pressure gate in route tests~~ | **Shipped 2026-05-18.** | The `gate_video_generation` + `gate_image_generation` pre-flight checks in [backend_service/helpers/memory_gate.py](backend_service/helpers/memory_gate.py) read live psutil via `snapshot_memory_signals()`. On a busy dev box (parallel pytest + vitest + Tauri running) the host legitimately sits at >92% memory pressure and the route returns `503 — Memory pressure is 97% — video generation would likely OOM`. The 7 `VideoGenerateRouteTests` cases in [tests/test_video_routes.py](tests/test_video_routes.py) + the 2 image equivalents in [tests/test_backend_service.py](tests/test_backend_service.py) (`test_image_generate_unloads_idle_video_runtime_first` + `test_image_generate_rejects_while_video_generation_active`) never mocked this dependency, so a half-full RAM box would surface them as flake. Fix: `setUp` patches `backend_service.helpers.memory_gate.snapshot_memory_signals` with a fixed `(64.0, 10.0)` return — 64 GB available, 10% pressure — so every assertion exercises the actual route logic and FastAPI handler shape, not the host OS state. `tearDown` stops the patch. The function-local `import` in [routes/video.py:335](backend_service/routes/video.py) means the patch lives at the source module rather than `video_routes` namespace; this works for both the image and video gates since they share the same `snapshot_memory_signals` helper. Repro: was deterministic when running `pytest tests/test_mlx_video.py tests/test_video_routes.py` in that order (the mlx-video tests' MLX import allocations briefly pushed the box past the 92% gate). | +| ~~FU-062~~ | ~~Bump `turboquant-mlx-full` floor `>=0.3.0` → `>=0.4.0`~~ | **Shipped 2026-05-25 (v0.9.3).** | Upstream `turboquant-mlx-full` 0.4.1 on PyPI (installed was 0.3.0, FU-001 pin). v0.4.0 added **expert streaming** — pages router-selected MoE experts from disk per token, runs models whose weights exceed available RAM. Live-validated upstream against `Qwen3.6-35B-A3B` (35B sparse) on a 16 GB Mac mini in under 4 GB RAM, output bit-identical to fully-resident model. Compounds with our existing Hadamard rotation + Lloyd-Max codebook K/V compression. Floor bump only — no API changes required, runtime continues to call `TurboQuantKVCache` with the same signature. Pin lives in [pyproject.toml](pyproject.toml) `[turboquant]` extra. Apple Silicon only (CUDA users stay on the `llama-server-turbo` binary path via FU-001's parallel track). | +| ~~FU-063~~ | ~~Bump `mlx-vlm` floor `>=0.4.0` → `>=0.5.0`~~ | **Shipped 2026-05-25 (v0.9.3).** | Upstream `mlx-vlm` 0.5.0 on PyPI (installed was 0.4.4). Minor bump, no API breakage at our call surface (`mlx_vlm.load` + `mlx_vlm.generate` from [mlx_worker_multimodal.py](backend_service/mlx_worker_multimodal.py)). Floor bump in [pyproject.toml](pyproject.toml) `[mlx-vlm]` extra; loose `>=` semantics mean existing 0.4.x installs are still satisfied locally, but fresh installs pick up the newer wheel which carries the upstream Qwen3.5-VL + GLM-4.5V fixes. | +| ~~FU-064~~ | ~~Add `ggml-org/Qwen3.6-{27B,35B-A3B}-GGUF` non-MTP catalog rows~~ | **Shipped 2026-05-25 (v0.9.3).** | ggml-org published canonical Q8_0 non-MTP companion packs on 2026-05-22 alongside the MTP variants we wired in FU-047. Two new rows in [text_models.py](backend_service/catalog/text_models.py) `qwen-3-6` family: `ggml-org/Qwen3.6-27B-GGUF` (Q8_0, 29 GB, dense) + `ggml-org/Qwen3.6-35B-A3B-GGUF` (Q8_0, 37 GB, MoE). Catalog note steers users at the MTP siblings when they want spec-dec. No runtime changes — direct `llama.cpp` lane, same as the lmstudio-community Q4_K_M variants already shipping. | +| FU-065 | Pin `llama-cpp-turboquant` to a commit hash instead of branch HEAD | Trigger: any user-reported build divergence between two install runs, OR a release-build gate where reproducibility matters more than tracking upstream. | [scripts/build-llama-turbo.sh](scripts/build-llama-turbo.sh) + [scripts/update-llama-turbo.sh](scripts/update-llama-turbo.sh) currently clone `TheTom/llama-cpp-turboquant` at branch `feature/turboquant-kv-cache` (`LLAMA_TURBO_BRANCH` env var), then `git reset --hard origin/$TURBO_BRANCH`. Two installs at different times can ship different binaries — the same drift problem FU-033 fixed for `dflash-mlx`. Today's branch HEAD is `2cbfdc62a1a047b01377948dfdede8cb6a744866`. Plan: add `LLAMA_TURBO_COMMIT="${LLAMA_TURBO_COMMIT:-2cbfdc62...}"` to both scripts, `git checkout "$LLAMA_TURBO_COMMIT"` after fetch, surface the hash in `llama-server-turbo.version`, and add a sync-assert to `pre-build-check` that compares the build-script pin to a value in [pyproject.toml](pyproject.toml) or a dedicated `UPSTREAM_PINS.md`. Defer because (a) branch is single-purpose with low churn — author is the same TheTom we already trust for `turboquant_plus`; (b) we already have the v0.9.2 → v0.9.3 release with this code path working. | +| FU-066 | Audit `cache-strategy-matrix` runner against bumped `turboquant-mlx-full` 0.4.x | When FU-062's bump lands in CI or when a user reports a TurboQuant regression. | The runner's TurboQuant cell (`mlx-community/Qwen3-0.6B-4bit × cacheStrategy=turboquant cacheBits=3`) passed against 0.3.0 with output hash `b4337bc07457` (FU-051 evidence). 0.4.x's expert-streaming code path is a no-op for dense 0.6B but flips on for MoE models like `mlx-community/Qwen3.6-35B-A3B-4bit` — worth a one-time live capture of an MoE turboquant cell against the 0.4.x wheel to lock in a baseline hash. No code changes; just record the number once the bumped wheel is installed on the M4 Max box. | +| ~~FU-072~~ | ~~Restore `vision` capability to Qwen3.5 + Qwen3.6 families (reverse FU-040)~~ | **Shipped 2026-05-28.** | FU-040 (2026-05-10) removed `vision` from Qwen3.6-27B + family, asserting the dense model was text-only with vision on "a separate `Qwen3.6-27B-VL` we don't ship." Re-checking upstream on 2026-05-28: **every** Qwen3.5/3.6 `config.json` now ships `architectures: [Qwen3_5ForConditionalGeneration]` / `[Qwen3_5MoeForConditionalGeneration]` with `vision_config` + `image_token_id` + `vision_start/end_token_id` — the base models are natively multimodal. `mlx-vlm` ships `qwen3_5` + `qwen3_5_moe` model support, and the `ggml-org/*-GGUF` packs include an `mmproj-*.gguf` sibling (auto-wired by `llama_cpp_engine._resolve_mmproj_path` → `--mmproj`). The catalog was also internally inconsistent (Qwen3.5-9B tagged vision, Qwen3.5-4B not, same arch). Re-added `vision` across both families in [text_models.py](backend_service/catalog/text_models.py): qwen-3-6 family-level + all 11 variants; qwen-3-5 family-level + `Qwen3.5-4B` (vision+video, matching its 9B sibling) + `lmstudio-community/Qwen3.5-9B-GGUF`. **Safety net (why this can't resurrect the FU-040 broken-button bug):** the composer "Attach image" affordance ([ChatComposer.tsx:129](src/features/chat/ChatComposer.tsx)) reads the *runtime* `supportsVision`, which [catalog/capabilities.py](backend_service/catalog/capabilities.py) demotes to False for the MLX worker (carries no images today) and gates on actual `--mmproj` resolution for GGUF ([llama_cpp_engine.py:737](backend_service/inference/llama_cpp_engine.py) `visionEnabled=attempt_mmproj_path is not None`). So the catalog `vision` tag now drives only the variant-picker / discover badges (capability-in-principle), while the functional button stays runtime-accurate. `gemma-4` was already correctly vision-tagged (mlx-vlm `gemma4` support) — left untouched. Catalog parses + `test_capabilities` / `test_mmproj_vision` green. | +| ~~FU-075~~ | ~~MLX spec-dec silently broken — stale `configure_full_attention_split` import~~ | **Shipped 2026-05-29.** | **Highest-impact bug this sweep.** Inspecting the matrix runtimeNotes (not just pass/fail) revealed the MLX DFlash / DDTree / MTPLX cells were *passing the weak non-empty-output check while NOT actually running spec-dec* — `actual_strategy: native`, note `dflash-mlx could not be imported (cannot import name 'configure_full_attention_split' from 'dflash_mlx.runtime')`. Root cause: dflash-mlx 0.1.5 moved the pre-0.1.5 top-level `configure_full_attention_split` onto the per-family `target_ops` adapter (the FU-006 migration that rewrote `ddtree.py` — but [mlx_worker_lifecycle.py:153](backend_service/mlx_worker_lifecycle.py) was missed). Python evaluates the whole `from … import a, b` line, so the failed `configure_full_attention_split` symbol killed the co-imported `load_draft_bundle` too → `_dflash_generator` never loaded → **every** MLX spec-dec path fell back to standard generation for all users. Fix: import `load_draft_bundle` + `resolve_target_ops` (both still top-level), resolve the adapter, and call `target_ops.configure_full_attention_split(...)` only for the `hybrid_gdn` family (it's a no-op for pure-attention Qwen3/3.5/3.6 — upstream only calls it there). Live-verified after fix: DFlash note "DFLASH speculative decoding active (draft: z-lab/Qwen3-4B-DFlash-b16)", DDTree "DDTree active (budget=16)". | +| ~~FU-076~~ | ~~MTP tensor probe missed top-level `mtp.` keys → MTPLX never selected~~ | **Shipped 2026-05-29.** | The matrix MTPLX cell routed to the DFlash path instead of `MtplxEngine`. `RuntimeController._select_engine` gates MTPLX on `has_mtp_heads_strict(repo, path)`, which calls `model_has_mtp_tensors(path)` → scans the safetensors index against `_MTP_TENSOR_HINTS = ('mtp_heads.', 'mtp_decoder.', 'mtp_emb.', 'model.mtp.', '.mtp.')`. Every hint assumes a *nested* key, but Qwen3.5 / Qwen3.6 ship the MTP head as **top-level** `mtp.layers.*` / `mtp.fc.weight` (no leading prefix) — so the probe returned False on a genuinely MTP-bearing model and MTPLX was skipped. Live-confirmed: `model_has_mtp_tensors` returned False on the real `Qwen/Qwen3.5-4B` snapshot. Fix in [_mtp.py](backend_service/inference/_mtp.py): also match `tensor_name.startswith("mtp.")`. New `test_safetensors_index_with_top_level_mtp_keys` in [tests/test_inference.py](tests/test_inference.py). | +| ~~FU-077~~ | ~~MTPLX isolated venv had a truncated install (missing server deps)~~ | **Shipped 2026-05-29.** | After FU-076 routed correctly, `MtplxEngine` startup died: `ModuleNotFoundError: No module named 'numpy'` — and then `safetensors`, `uvicorn`, `fastapi`, `pydantic`, `mlx-lm`, `rich`… The `~/.chaosengine/mtplx-venv` was a *truncated* install (interrupted `pip install mtplx`), but the installer's verify only ran `import mtplx`, which succeeds because the server deps are imported lazily by `mtplx.server.openai` (not at package top level). Fixed the live venv with a full `pip install --upgrade mtplx` (0.3.5 → 0.3.7, pulled all deps). Hardened [scripts/install-mtplx.sh](scripts/install-mtplx.sh): the verify now imports `mtplx.server.openai` (the real server entrypoint) and auto-retries a full dependency install once before failing loudly, so a truncated install can't pass silently again. | +| ~~FU-078~~ | ~~MtplxEngine handed MTPLX a bare repo id instead of the local snapshot path~~ | **Shipped 2026-05-29.** | Final MTPLX blocker: `mtplx quickstart` died with "model is not available locally. Run: mtplx pull Qwen/Qwen3.5-4B" — it resolves a model *id* against its own registry/cache, not the HF hub cache. [mtplx_engine.py](backend_service/inference/mtplx_engine.py) set `model_arg = path or runtime_target or model_ref`, and for raw HF-org repos `path` is None while `runtime_target` is the *repo id* (`Qwen/Qwen3.5-4B`), so MTPLX got an id it couldn't find. Fix: whenever the candidate isn't an existing local directory, resolve the already-downloaded HF snapshot dir via `snapshot_download(model_ref, local_files_only=True)` (no network) and pass that. Live-verified: MTPLX now **loads + engages** (note "MTPLX MTP speculative decoding active (draft tokens: 1, model: Qwen3.5-4B)", reports 17.8 tok/s) instead of failing to start. Also fixed the matrix runner's `0.0 tok/s` (read `done.assistant.metrics.tokS`, not a non-existent top-level `tokensPerSecond`) + captured `dflashAcceptanceRate`. **Verified-genuine after these fixes: DFlash (33.2 tok/s), DDTree (31.4 tok/s), GGUF-MTP (14.7 tok/s), turboquant MLX/GGUF, triattention, native** — all stream real output with real throughput. MTPLX still has one remaining issue → FU-079. | +| ~~FU-080~~ | ~~Backend cold start dragged in torch via cache-strategy availability probes~~ | **Shipped 2026-05-29.** | `python -X importtime backend_service.app` measured **2.6 s**, of which **1.64 s was `diffusers.hooks`** (→ `torch` → `torch._dynamo` → `sympy`) — blowing the CLAUDE.md "< 2 s backend startup" target. Traced the chain: state init → system snapshot → `_get_cache_strategies()` → `registry.available()` instantiates every strategy and calls `is_available()`, and the 5 diffusion strategies (fbcache / taylorseer / magcache / pab / fastercache) answered availability by **actually importing `diffusers.hooks`** — pulling the whole torch stack onto the cold-start path on every launch. Fix: new [cache_compression/_diffusers_probe.py](cache_compression/_diffusers_probe.py) `diffusers_at_least(major, minor)` reads the installed version via `importlib.metadata.version` (metadata only — never executes `diffusers.__init__`, so no torch). Each `is_available()` now gates on the version (fbcache ≥0.36, the other four ≥0.38); the real `diffusers.hooks` import stays lazy inside each `apply_*` method (still raises a clean NotImplementedError on a broken install). Result: `diffusers` / `torch` / `mlx` are **no longer in `sys.modules` after `import backend_service.app`**, import time dropped **2.6 s → ~0.85 s**, and cold-start → first `/api/health` 200 is **2.34 s** (the native-backend MLX subprocess probe was already async — "detection still running" on first health, never blocked startup). Two subprocess-isolated regression guards in [tests/test_cache_strategies.py](tests/test_cache_strategies.py) (`StartupImportPurityTests`) assert neither `registry.available()` nor `import backend_service.app` pulls torch/diffusers, so this can't silently regress. All 5 diffusion strategies still report `available=True` against the installed diffusers 0.38. | +| FU-079 | MTPLX proxy doesn't surface incremental tokens to the chat stream (empty output) | Active — MTPLX-specific, lower priority (FU-048: MTPLX is ~flat-to-slower vs the alternatives, which all work). | After FU-075–078, the matrix MTPLX cell flipped from "fake pass via DFlash fallback" to **engine genuinely engaged but `FAIL — empty output`**: the loaded-model note confirms "MTPLX MTP active (draft tokens: 1)" and the done event carries a real `tokS` (17.8), but the streamed assistant text is empty (output SHA `e3b0c44298fc` = the empty-string hash). Confirmed the chat stream's incremental token field IS `{"token": "..."}` (DFlash/DDTree/GGUF-MTP/native all stream through it fine on the same `/api/chat/generate/stream` endpoint), so the gap is in `MtplxEngine`'s OpenAI-`/v1`-proxy → SSE adapter: it surfaces final metrics but not per-token deltas, leaving `full_text` empty for both the matrix runner AND the real Chat UI. Plan: inspect `MtplxEngine.generate` / its streaming proxy in [mtplx_engine.py](backend_service/inference/mtplx_engine.py), map the mtplx server's `/v1/chat/completions` SSE `choices[].delta.content` chunks onto our `{"token": ...}` event shape. Until fixed, MTPLX loads but produces no visible output — DFlash is the working MLX spec-dec lane for the same models (and faster per FU-048). | +| ~~FU-074~~ | ~~GGUF MTP speculative decoding had no UI toggle~~ | **Shipped 2026-05-28.** | FU-047 wired the GGUF MTP backend (`--spec-type draft-mtp`, gated on the `speculativeDecoding` request flag in [llama_cpp_engine.py:531](backend_service/inference/llama_cpp_engine.py)) + the `ggufMtpAvailable` capability flag, but never surfaced a UI control. The launch modal's only spec-dec toggles are DFlash (hidden for GGUF — "not supported with llama.cpp models") and MTPLX (Apple-Silicon MLX only), so a user loading `ggml-org/Qwen3.6-27B-MTP-GGUF` had **no way to enable** the lane — only the matrix runner could, by POSTing `speculativeDecoding=true` directly. The button audit (this turn) caught it. Added an `isMtpGgufRepo(repo)` helper in [runtimeSupport.ts](src/components/runtimeSupport.ts) (mirrors backend `is_mtp_gguf_repo`: MTP-flavoured name on a GGUF repo) + a "GGUF MTP" toggle in [RuntimeControls.tsx](src/components/RuntimeControls.tsx), shown only when `isGgufBackend && isMtpGgufRepo(selectedCanonicalRepo)` (FU-034 hide-when-not-applicable). It binds to the same `speculativeDecoding` flag the backend reads; no cache-strategy lock (GGUF KV cache is orthogonal to MTP draft decode, unlike MLX DFlash which forces native). Also patched the DFlash-availability reset effect (was clearing `speculativeDecoding` for any non-DFlash model — would have instantly un-ticked the GGUF-MTP box) to keep it on for `ggufMtpModelSupported`. Old binaries without `--spec-type` fall back to standard decode + a runtimeNote (backend FU-047 path) — acceptable since the bundled llama-server is current; a future refinement could additionally gate the toggle on the `ggufMtpAvailable` capability for old-binary boxes (needs the flag threaded through the ~8 RuntimeControls call sites). 8 new `isMtpGgufRepo` unit tests in [runtimeSupport.test.ts](src/components/__tests__/runtimeSupport.test.ts). Verified live: matrix `gguf MTP (Qwen3.6-27B)` cell PASS (sha 74a1eca8b3b4). | +| ~~FU-073~~ | ~~Matrix MTPLX cell targeted a non-MTP VL model~~ | **Shipped 2026-05-28.** | `scripts/cache-strategy-matrix.py` `MID_MLX_MTPLX_CAPABLE` was `mlx-community/Qwen3.5-4B-bf16` — a VL conversion (ships `video_preprocessor_config.json`) that carries no MTP heads and is absent from both `MTP_MODEL_MAP` and `_MTP_ALIASES`, so the MTPLX cell could never have exercised MTP even with the model on disk (it'd fail the `has_mtp_heads_strict` tensor probe). Switched to the canonical `Qwen/Qwen3.5-4B`, which is a direct `MTP_MODEL_MAP` key (verified `mtp.layers.*` + `mtp.fc.weight` in its safetensors index), a catalog variant (so it passes the `library_refs` check), and downloaded to exercise the lane. Pairs with the FU-070 download-skip classifier so the cell reports honestly on boxes without the model. | +| ~~FU-071~~ | ~~DDTree availability probe checks pre-0.1.5 symbol names~~ | **Shipped 2026-05-28.** | The cache-strategy matrix `ddtree spec-dec` cell skipped with *DDTree runtime not available* even though `dflash_mlx` 0.1.5.1 is installed and `backend_service/ddtree.py` works. Root cause: `dflash.is_ddtree_available()` ([dflash/__init__.py](dflash/__init__.py)) source-greps the installed `dflash_mlx.runtime` for three required symbols and the list was stale — it required `target_forward_with_hidden_states`, which dflash-mlx 0.1.5 **renamed** to the per-family adapter `target_ops.forward_with_hidden_capture` (the same FU-006 migration that rewrote our `ddtree.py` to call `resolve_target_ops(target_model)`). The probe was never updated alongside that rewrite, so it required a symbol that (a) no longer exists in any modern dflash-mlx build (`grep -c` = 0 in the installed `runtime.py`) and (b) our own code no longer uses. Confirmed the real contract our DDTree path imports: `resolve_target_ops` (ddtree.py adapter entry), `load_draft_bundle` (worker lifecycle), `stream_dflash_generate` (speculative). Updated `required_symbols` to those three; dropped the obsolete name + the unused `load_target_bundle`. `dflash.is_ddtree_available()` now returns `True` on this M4 Max box. 4 new `DDTreeAvailabilityProbeTests` in [tests/test_dflash.py](tests/test_dflash.py) mock the runtime source so a future rename can't silently regress the probe again. Note: when FU-057 bumps dflash-mlx to 0.1.7 (which removes `configure_full_attention_split` and reshapes `stream_dflash_generate`), this probe + the lifecycle import need re-checking in lockstep. | +| ~~FU-070~~ | ~~Matrix runner: classify missing-download as SKIP, not FAIL~~ | **Shipped 2026-05-28.** | The full `scripts/cache-strategy-matrix.py` sweep on 2026-05-28 reported the `gguf MTP (Qwen3.6-27B)` cell as **FAIL** — `POST /api/models/load -> 500: Cannot load 'ggml-org/Qwen3.6-27B-MTP-GGUF': No .gguf, .safetensors, or pytorch weights found in HF cache entry.` Root cause: the repo had an empty `~/.cache/huggingface/hub/models--ggml-org--Qwen3.6-27B-MTP-GGUF/` dir (4.0 KB, only `refs/main`, dated May 16 — an interrupted pull), and the runner's `skip_reason` library check uses `caps.library_refs`, which is built from the **catalog** (every variant repo from `/api/workspace`), not from what's actually downloaded. So a catalogued-but-undownloaded model passes the library check and only errors at load — reported as a product FAIL when it's really a missing download (same false-positive class as FU-053). Fix: new pure helper `classify_load_skip(msg)` in [scripts/cache-strategy-matrix.py](scripts/cache-strategy-matrix.py) matches the backend's 'no weights found in HF cache entry' markers; `run_cell` now wraps the load call separately and converts that specific error into `skipped=True, skip_reason="weights not downloaded ()"` instead of a failure. Genuine load errors (OOM, etc.) still surface as fails. 4 unit tests in [tests/test_cache_strategy_matrix_runner.py](tests/test_cache_strategy_matrix_runner.py) (`ClassifyLoadSkipTests`) pin the classification. The dflash/mtplx cells already skipped correctly because their target models (`mlx-community/Qwen3-4B-bf16` / `Qwen3.5-4B-bf16`) aren't catalog variants so they never entered `library_refs`. **To actually exercise the GGUF-MTP lane (FU-047/FU-052 trip-wire), download `ggml-org/Qwen3.6-27B-MTP-GGUF` first**, then re-run full. | +| ~~FU-069~~ | ~~Bump `turboquant-mlx-full` floor `>=0.4.0` → `>=0.5.0`~~ | **Shipped 2026-05-28.** | Upstream `turboquant-mlx-full` 0.5.0 on PyPI (FU-062 had just floored at 0.4.0 on 2026-05-25). v0.5.0 builds on the v0.4.0 expert-streaming path (FU-062) with **parallel expert prefetch** — the missing MoE experts for each layer are read on a thread pool (`--prefetch-workers`, default `8`) so SSD latency hides behind compute. Upstream-reported **~1.9× faster decode** at a tight cache budget, still bit-identical output. `--prefetch-workers 1` restores the serial v0.4.0 behaviour. No API change at our call surface — runtime still constructs `TurboQuantKVCache` with the same signature; the new flag is converter/runtime-side. Floor bump only in [pyproject.toml](pyproject.toml) `[turboquant]` extra; loose `>=` so existing 0.4.x installs stay satisfied locally. Apple Silicon only. Folds in the spirit of FU-066 (the matrix MoE-turboquant baseline should be captured against 0.5.0 once the wheel is installed on the M4 Max box). | +| ~~FU-068~~ | ~~MLX probe timeout 12 s → 20 s~~ | **Shipped 2026-05-25 (v0.9.3).** | E2E full-sweep Phase 1 surfaced three intermittent fails on a freshly-booted backend — `MLX native cache` / `MLX TurboQuant cache` / `fused attention flag` all returned `MLX backend requested but unavailable: ...mlx_worker probe timed out after 12.0 seconds`. Measured cold-start: `time .venv/bin/python -m backend_service.mlx_worker probe` = **12.43 s** on M4 Max / Python 3.11 against current `mlx 0.31.2` + `mlx-lm 0.31.3` + `mlx-vlm 0.4.4` — 0.4 s past the 12.0 s ceiling. The 12.0 s value was an arbitrary default from the v0.8.0 `capabilities.py` extract (commit `f91709e`), never tuned. Bumped to **20.0 s** in [backend_service/inference/capabilities.py](backend_service/inference/capabilities.py) `_probe_native_backends` — ~60% headroom over today's envelope. Phase 5 video gen + Phase 1 GGUF / DFlash / cache-preview already passed (proves MLX itself works once the probe lands), so this was a pure cold-boot probe timing issue, not a regression from the FU-062 / FU-063 floor bumps (which are loose `>=`, no installed package changed). | +| FU-067 | Watch dflash-mlx for v0.1.8+ migration guide (FU-057 is multi-hour, deferred) | Trigger: (a) upstream publishes v0.1.8 with a stability commitment + migration guide, OR (b) we hit a concrete user-visible bug on the orphan `fada1eb` pin, OR (c) a shipped catalog model needs a v0.1.6+ feature (adaptive verify / Gemma4 backend / Qwen3-Next GDN). | Dup of FU-057's trigger but resurfaced after the v0.9.3 upstream scan confirmed v0.1.7 is now on PyPI (`pip install dflash-mlx==0.1.7` resolves) and tagged at commit `210a0fc1`. Plan-of-record stays FU-057's six-step migration. Re-checking quarterly via `git ls-remote --tags` for `v0.1.8` / `v0.2.0` release tags — if upstream publishes a migration guide alongside, the cost drops dramatically. | | ~~FU-061~~ | ~~"Watching upstream" badge + disabled download for tracked-only image seeds~~ | **Shipped 2026-05-18.** | User-reported gap: downloaded `baidu/ERNIE-Image-Turbo` from Image Discover (it sits in `LATEST_IMAGE_TRACKED_SEEDS`), expected it in the Studio dropdown, didn't appear. Root cause: tracked seeds are discovery-only — Studio's dropdown is fed by `IMAGE_MODEL_FAMILIES` which requires explicit pipeline routing (flow-match flags, sampler registry, scheduler defaults). ERNIE-Image (+ Nucleus-Image, Z-Image, HiDream, GLM-Image, FLUX.2 family) has no diffusers-routable Studio variant yet. Fix path A picked over path B (full per-family pipeline wiring) — surgical UX disambiguation. **Backend:** new `_is_launchable_image_repo(repo_id)` helper in [backend_service/helpers/images.py](backend_service/helpers/images.py) returns True only when `repo_id` resolves to a curated `IMAGE_MODEL_FAMILIES` variant. Wired into both payload sites — `_tracked_latest_seed_payloads` (line 411) + the live-HF lane (line 622) — so every Discover row carries `trackedOnly: bool`. **Frontend:** new `trackedOnly?: boolean` field on `ImageModelVariant` ([src/types/image.ts](src/types/image.ts)). [ImageDiscoverTab.tsx](src/features/images/ImageDiscoverTab.tsx) chip row gains a "Watching upstream" badge + tooltip when `trackedOnly`. Action column branches first on `trackedOnly` → renders a disabled `IconActionButton` with tooltip "Watching upstream — Studio playback for this family isn't wired yet. Catalog entry is for awareness; download won't unlock Studio." instead of the Generate / Download / Resume CTAs. Backward-compat: existing curated families have `trackedOnly: undefined` → falsy → no UX change. **Tests:** new `TrackedOnlyFlagTests` in [tests/test_image_discover.py](tests/test_image_discover.py) — 5 cases covering `_is_launchable_image_repo` (FLUX.1-dev + SDXL = true; ERNIE-Image / Nucleus-Image = false; empty = false), `trackedOnly: True` on ERNIE seed payload, and the negative case where a tracked seed that IS in IMAGE_MODEL_FAMILIES must NOT carry the flag (forward-compat for catalog evolution). **Follow-up path B (deferred):** wire ERNIE-Image / Nucleus-Image / Z-Image / HiDream / GLM-Image / FLUX.2 family as real launchable families via per-family pipeline detection in `image_runtime`. Multi-hour per family, gated on diffusers' upstream support landing for each architecture. | --- diff --git a/backend_service/catalog/text_models.py b/backend_service/catalog/text_models.py index abaa88a..5fbb153 100644 --- a/backend_service/catalog/text_models.py +++ b/backend_service/catalog/text_models.py @@ -103,16 +103,20 @@ "popularityLabel": "Featured family", "likesLabel": "Qwen official", "badges": ["Reasoning", "Coding", "Agents", "Long context"], - # FU-040 (2026-05-10): dropped ``vision`` from the family-level - # capabilities.
