Module hubs 

Recognized project hub Markdown files at the workspace root.

Rust / open-source norms:

• README.md — project front door
• CHANGELOG.md — Keep a Changelog + SemVer ship history

Optional planning surfaces (agent HITL — never required for a healthy brain):

• ROADMAP.md, BACKLOG.md — priorities / unshipped work

These are indexed under stable node ids (readme, changelog, …) so agents can query and context-pack them reliably when the files exist. Absence is fine: doctor tips are info-level only. Rustbrain never invents changelog entries or plan tasks — it only densifies what is already on disk after sync.
