Module config 

Environment-driven configuration management. Environment-driven configuration for Rusty Memory.

This module loads and validates settings once at startup (via init_config) and exposes a global, read‑only view through get_config. The configuration powers both the HTTP API and the MCP server and includes:

• Qdrant connectivity (QDRANT_URL, QDRANT_COLLECTION_NAME, QDRANT_API_KEY?).
• Embedding provider/model (EMBEDDING_PROVIDER, EMBEDDING_MODEL, EMBEDDING_DIMENSION, OLLAMA_URL?).
• Chunking overrides (TEXT_SPLITTER_CHUNK_SIZE?, TEXT_SPLITTER_CHUNK_OVERLAP?, TEXT_SPLITTER_USE_SAFE_DEFAULTS?).
• Search ergonomics (SEARCH_DEFAULT_LIMIT?, SEARCH_MAX_LIMIT?, SEARCH_DEFAULT_SCORE_THRESHOLD?).
• Summarization (SUMMARIZATION_PROVIDER?, SUMMARIZATION_MODEL?, SUMMARIZATION_MAX_WORDS?).
• HTTP server port (SERVER_PORT?).

Most fields are optional with sensible defaults; invalid combinations are flagged early with descriptive errors so misconfiguration is easy to diagnose.
