P1 #1: ``_release_safetensors_chat_for`` now re-reads ``active_model_name`` and ``loading_models`` after each unload AND runs a final sweep against the initial owned-name set. The previous helper trusted ``unload_model() -> True`` even though the orchestrator can respond ``unloaded`` while still holding weights or a concurrent ``load`` can repopulate the tracker between calls. Per-name and global post-state mismatches now raise HTTP 503 so the caller retries. P1 #2: same post-state guarantee inside ``_release_chat_backend_for_diffusion`` for direct backend callers. ``DiffusionBackend.load_model`` now raises RuntimeError when the safetensors tracker still owns a previously-resident name after the unload, matching the route-level helper. The route layer's existing classifier maps the new wording to HTTP 503. P1 #3: ``DiffusionBackend.load_model`` now preflights the full diffusers repo (or explicit GGUF ``base_repo``) via ``hf_hub_download(filename="model_index.json")`` BEFORE the chat / export unload runs. The GGUF path was already covered by the existing ``hf_hub_download(gguf_filename)`` round-trip; the full-repo path used to skip validation and let a typo / private / gated repo only surface inside ``from_pretrained`` AFTER the user's chat model was already dropped. Local paths are checked structurally (must be a directory containing ``model_index.json``) so we do not network-round-trip for an on-disk miss. Error messages route through ``_display_repo_id`` so an absolute filesystem path does not leak the operator's layout. P1 #6: ``/api/inference/unload`` (the direct chat unload endpoint) now treats ``unload_model() -> False`` AND a leftover state (``is_loaded`` / ``is_active`` / ``loading_model_identifier`` for GGUF, ``active_model_name`` / ``loading_models`` for safetensors) as 503 instead of unconditionally responding ``status="unloaded"``. The UI used to show the model as gone while the backend still owned VRAM. P2 #7: extended the /images/load RuntimeError -> HTTPException marker list with ``still active or loading after unload`` and ``still loading after unload``. Round 18 introduced these exact phrasings on the backend side; without the extension a retryable unload failure was returning HTTP 400 to the user instead of 503. P2 #8: removed the unused ``unsloth_backend = get_inference_backend()`` eager construction in the GGUF chat-load branch. Eager construction made the GGUF-only path needlessly fail or pay startup cost when the safetensors backend was unavailable / lazy; ``_release_safetensors_chat_for`` already handles that case as a no-op. All 85 diffusion-relevant + 98 related backend tests pass locally. |
