Selection rules:
  Most note-targeting commands accept either --id or a title/search selector.
  --id is exact and preferred for automation.

Output conventions:
  Human-readable commands usually print tab-separated rows.
  Commands with --json emit structured JSON for agent consumption.

Examples:
  bear -v notes --limit 20
  bear -vv inspect-note --title \"Scratch\"
  bear -vvv auth
  bear notes --limit 20 --json
  bear open-note --title \"Scratch\"
  bear add-text --title \"Scratch\" \"more text\"
