sqlite-graphrag 1.2.5

Persistent GraphRAG memory for Claude Code, Codex, Cursor, and 27 AI agents — one self-contained ~19 MiB Rust binary, zero daemon. Never re-explain your codebase again. Hybrid retrieval (FTS5 BM25 + cosine similarity + multi-hop graph traversal) surfaces the right memory in milliseconds. Embedding and entity enrichment run as parallel REST calls against your cloud LLM — no fragile headless subprocesses, no ONNX runtime, no model downloads. Soft-delete with full version history, transactional atomic writes, BLAKE3-tracked mutations. OAuth-only: raw API keys ABORT the spawn.

//! `--dry-run` preview: report what an ingest would do, touch nothing.

//! Runs after the name plan is resolved and before the database is opened or
//! any model is loaded, so the operator can inspect name derivation, skipped
//! files and chunk/token budgets at zero cost.
