- spawn_agent default profile: correct the false "omit profile_id to use
  this developer profile" — omitting profile_id inherits navi_code (the
  parent), not developer; set profile_id explicitly to pick another profile.
- Safety Rules: scope strict confirmation to destructive/irreversible
  operations (rm, delete, wholesale write overwrite, drop table, force-push);
  state explicitly that routine edit/edit_lines do not require confirmation.
- Workflow Understand: soften the hard "start with docs/index.md" to a soft
  "read notes/docs first (see NAVI.md and Documentation sections below)" so
  it no longer conflicts with the NAVI.md-first entry point.
- Documentation: add a branch for projects with no docs/ — propose creating
  one (with user approval) or record in NAVI.md that docs are absent/not
  needed.
- Execution environment: document terminal action="run" for one-off commands
  (tests, git status, lint, py_compile); persistent terminals only for
  long-running processes.

Findings 6 (subagent briefing toolset), 7 (subagent delegation wording),
8 (planning/context-org tools) deferred for later work.
