-## How it works
-
-Vectorless splits document understanding into two layers:
-
-- **Compile (Rust).** Documents are parsed and run through a multi-pass compile pipeline (`crates/vectorless-compiler/`) that builds a navigable tree plus retrieval-acceleration artifacts (concepts, navigation hints, reasoning chains, overlap maps). The output is a `DocumentNavigator` (`crates/vectorless-primitives/`) exposed to Python over PyO3.
-- **Ask (Python).** Queries are answered by an LLM-driven reasoning loop (`vectorless/ask/`) — a Query Plan, an Orchestrator running Worker agents that issue shell-style navigation commands (`ls`, `cd`, `cat`, `grep`, `find`, `head`, `wc`, `chain`) against the compiled document, evidence evaluation with replanning, and a rerank+synthesize step.
