#49 - PRD: Rust indexing core vertical slice

What to build

Run the Agent Sufficiency guardrail matrix against TypeScript-produced and Rust-produced indexes to ensure the Rust path does not increase generic Read/Grep fallback or break existing Flow connectivity.

Acceptance criteria

• This repository is indexed with both TypeScript and Rust engines for representative ZCodeGraph flow prompts.
• Excalidraw is indexed with both TypeScript and Rust engines for representative Excalidraw flow prompts.
• Generic Read fallback does not increase for the Rust path.
• Generic Grep/Bash fallback does not increase for the Rust path.
• Flow section connectivity does not regress for prompts that were already connected.
• Differences are recorded as graph coverage, scope shallow, scope noisy, or agent ignored evidence.
• Guardrail results are stored in a compact repo document.
