The rust-skills directory is now a regular directory, not a git submodule. This fixes the CI error: 'No url found for submodule path rust-skills' The rust-skills rules are included as regular files in the repository. Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>
- Format .map_err() closures consistently across model_cache.rs, semantic_cleaner_impl.rs, inference_engine.rs - All error propagation operators (?) preserved after formatting - Fixes CI formatting checks Related to Issue #9 - AI Semantic Cleaning Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>
Critical bug: Relevance scoring was discarding embedding vectors, resulting in "Generated 0 chunks with embeddings" logs and empty embeddings fields in JSONL output (lost 49536 dimensions). Changes: - Updated filter_by_relevance() to use filter_with_embeddings() - Restored embeddings to chunks after filtering (chunk.embeddings = Some(embedding)) - Added length mismatch validation to prevent silent data loss (mem-prevent-data-loss) - Updated documentation with safe embedding verification (no unwrap()) - Added integration test for embeddings preservation validation - Added test example to verify 384-dimension embeddings Fixed rules: - Fixed unwrapped access in doc example (Critical security antipattern) - Added length validation (mem-prevent-data-loss) - Applied doc-all-public (complete documentation) Verification: - Before: "Generated 0 chunks with embeddings" → JSONL has embeddings: [] - After: "Generated 149 chunks with embeddings" → JSONL has full embedding vectors - All generated chunks have embeddings.is_some() after fix Fix mitigates: mem-double-clone, mem-optimal-copy (performance)
…servation Includes AI feature implementation with ONNX Runtime, embedding preservation fix, and comprehensive documentation. Changes: - Migrated from tract-onnx to Ort (ONNX Runtime 2.0.0-rc.12) - Added --download-images and --download-documents features - Added --clean-ai flag for semantic chunking with embeddings - Downloaded model: all-MiniLM-L6-v2 (90MB, cpu_only, sha256 verified) - Fixed embeddings preservation in semantic filtering - Added --features ai CLI option and compilation support - Updated Cargo.toml with all-new dependencies (ort, ndarray, etc) - Added example: examples/test_ai.rs for AI pipeline testing - Updated CLI.md with AI feature documentation - Added README Recent Bugs section Infrastructure: - Implements ModelResolver pattern for manual model download - Fixes ort inputs: token_type_ids and attention_mask required - Validates model integrity using sha256 verification - Implements proper model cache management (~/.cache/rust-scraper) Dependencies added: - ort: 2.0.0-rc.12 (CPU-only BERT model support) - ndarray: ^0.17 - regex: ^1.0 - trace-subscriber: ^0.3 - tempfile: ^3.6
