rdar

rdar installs the radar command, a fast local repository router written in Rust. The core project is currently private. This small, auditable launcher downloads a stripped release from https://radar.sanixdk.xyz, verifies its SHA-256 checksum, caches it per native version and platform, then forwards arguments. Launcher release 0.5.1 installs the pinned radar 0.5.0 Linux x86_64 artifact. Other release targets stay disabled until their native builds pass the same verification.

cargo install --locked rdar
radar --version
cd your-project
radar map
radar query "where is the auth boundary?" --source

Measured results

• Live navigation input: 15,407 to 4,249 tokens, 72.4% lower.
• Live reference cost: $0.1555 to $0.0564, 63.7% lower.
• Accuracy: 20/21 to 21/21 in the locked live navigation matrix.
• Retrieval: expected source anchor in the top three for 40/40 questions.
• Generated 10,000-file query: 28.74 ms p95 with zero model calls.

Radar combines deterministic tree-sitter extraction, compact lexical fingerprints, exact-symbol routing, confidence-based abstention, bounded source-span verification, incremental content-addressed caches, and tiny committed MAP.md routers. Maps and caches are derived navigation data; source files remain authoritative.
