Alexander Whitestone	3fca28b1c8	feat: export embedding backends from mnemosyne __init__	2026-04-12 05:07:55 +00:00
Alexander Whitestone	1f8994abc9	docs: mark embedding_backend as shipped in FEATURES.yaml	2026-04-12 05:07:29 +00:00
Alexander Whitestone	fcdb049117	feat: CLI --backend flag for embedding backend selection ... - search: --backend ollama|tfidf|auto - rebuild: --backend flag - Auto-detects best backend when --semantic is used	2026-04-12 05:07:14 +00:00
Alexander Whitestone	85dda06ff0	test: add embedding backend test suite ... Tests cosine similarity, TF-IDF backend, auto-detection, and fallback behavior.	2026-04-12 05:06:24 +00:00
Alexander Whitestone	bd27cd4bf5	feat: archive.py uses embedding backend for semantic search ... - MnemosyneArchive.__init__ accepts optional EmbeddingBackend - Auto-detects best backend via get_embedding_backend() - semantic_search uses embedding cosine similarity when available - Falls back to Jaccard token similarity gracefully	2026-04-12 05:06:00 +00:00
Alexander Whitestone	fd7c66bd54	feat: linker supports pluggable embedding backend ... HolographicLinker now accepts optional EmbeddingBackend. Uses cosine similarity on embeddings when available, falls back to Jaccard token similarity otherwise. Embedding cache for performance during link operations.	2026-04-12 05:05:17 +00:00
Alexander Whitestone	3bf8d6e0a6	feat: add pluggable embedding backend (Ollama + TF-IDF) ... Implements embedding_backend from FEATURES.yaml: - Abstract EmbeddingBackend interface - OllamaEmbeddingBackend for local sovereign models - TfidfEmbeddingBackend pure-Python fallback - get_embedding_backend() auto-detection	2026-04-12 05:04:53 +00:00
