Documentation freshness checklist

Review these together whenever a new onboarding-facing workflow or command ships:

  1. README.md
  2. docs/index.md
  3. docs/getting_started.md
  4. docs/choose_your_path.md
  5. docs/reference/workflow_map.md
  6. docs/reference/module_map.md
  7. docs/reference/public_api_map.md
  8. docs/reference/cli_reference.md
  9. the relevant tutorial page
  10. the relevant packaged example under src/cranalytics/examples/

Treat this checklist as part of the definition of done for onboarding-facing changes. If one of these surfaces changes, the rest should be reviewed in the same pass.
