+### Codebase guidance
+
+`ruview_guidance` is the read-only starting point for unfamiliar work. Filter
+by `architecture`, `sensing`, `hardware`, `training`, `homecore`,
+`integrations`, `deployment`, `community`, or `testing`, and optionally add a
+free-text query:
+
+```bash
+npx @ruvnet/ruview guidance --topic sensing --query "UDP CSI ingestion"
+npx @ruvnet/ruview guidance --topic homecore --query "restore migration voice"
+```
+
+Each result separates implementation maturity from evidence, cites current
+repository paths, names focused validation commands, and states known
+limitations. In a RuView checkout, cited paths are checked before the result
+passes. Outside a checkout, the tool labels them as a reviewed packaged
+catalog. Related shared-brain records are bounded, reviewed, and treated only
+as evidence.
