- Filter non-model files in scanner when folder_paths category extensions are empty
- Skip candidates with known non-model extensions in find_matches
- Add .engine, .patch, and .tflite to MODEL_EXTENSIONS
- Add unit tests for empty extension directory scanning and matcher candidate filtering
- Recover completed .part files on HTTP 416 without deleting and redownloading
- Add stream stall detection and automatic reconnect for interrupted socket reads
- Implement persistent download state store and pause/resume lifecycle controls
- Add RateLimitCoordinator and ConnectivityGuard circuit breaker for requests
- Support proxy_url configuration and validate aria2 proxy settings
- Add unit tests for 416 recovery, stall reconnect, state store, and network guard
- Drain aria2 daemon stderr in a background thread to prevent Windows pipe buffer saturation and deadlock
- Promote critical disk write and permission errors from aria2 stderr to warnings
- Automatically refresh expired signed CDN URLs and resume downloads via aria2 continue=true
- Shield addUri against mid-registration cancellations to prevent orphaned downloads
- Retry Range requests directly on target URL when redirects drop the Range header in Python downloads
- Add auto-reconnect stream loop on transient socket disruptions with seamless partial-hash resumption
- Increase default download chunk size to 4MB for improved I/O throughput
- Parse HTTP 429 Retry-After headers for informative rate limit reporting
- Add unit test suite covering new aria2 and Python downloader resilience behaviors
- Omit blocking checksum and check-integrity options from aria2 transfers to prevent long pauses at 100% on large models
- Run SHA-256 integrity verification asynchronously in a background thread via Python hashlib
- Update download progress and metadata sidecars upon background verification completion or mismatch
- Add unit tests for aria2 option omission and background verification
Add custom node adapter for ComfyUI_SmartModelLoader_Nova suite:
- Support 'Smart Model Loader [SML2]', 'CLIP Loader [SML2]', and 'LoRA Stack [SML2]'
- Parse and serialize canonical JSON configuration widget
- Extract diffusion models, VAE, CLIP text encoders, and LoRAs with strengths
- Enable model resolution by hash using per-resource SHA256 stored in the node
- Update model paths and SHA256 checksums in canonical JSON format during relinking
- Add unit and end-to-end integration tests
- Add paste handler (Ctrl+V) in Metadata tab for workflow JSON, images, and Civitai image URLs/HTML
- Resolve authentic .safetensors filenames and local ComfyUI model paths via Civitai modelVersionId
- Normalize prompt <lora:...> tags to authentic filenames and enrich transfer/loaded chip labels
Use order-insensitive token comparison in calculate_filename_confidence
so variant names with reordered tokens (e.g., int8_convrot vs convrot_int8)
score higher. Replace first-match partial matching in HuggingFace source with
best-match selection based on filename confidence, and surface confidence in
search results.
Reuse model metadata across _find_civitai_file_in_model calls within a single search, avoid resolve_urn when modelVersions already contains usable file lists, and add tests for request-count behavior.
- Preserve HuggingFace textual model/version IDs in download metadata instead of coercing to integers
- Add convrot as a recognized model variant suffix
- Recognize numeric precision tokens with optional mixed/scaled suffixes (e.g. int8mixed, fp8scaled)
- Report partial batch search failures as informational notifications rather than errors
