"""Self-scoped user endpoints for the /home onboarding flow.

POST /api/me/onboarded toggles ``users.onboarded`` for the calling user
and writes an audit_log row distinguishing the trigger source:

- ``agnes_init``       — fired by the CLI's ``agnes init`` final step.
- ``self_acknowledged`` — fired by the on-page "I've already set this up"
  button shown to users who set up locally before /home shipped.
- ``self_unmark``      — fired by the on-page "Mark me as offboarded"
  button (visible once the user is onboarded).

The body's optional ``onboarded`` field defaults to ``True`` for
backward compat with existing ``agnes init`` calls. Pass ``false`` to
flip back — useful when an analyst wipes their workspace and wants the
inline install steps back, or when an operator demos the not-onboarded
view without an SQL UPDATE.

Idempotent — a second call still returns 200 and writes a second audit
row, so duplicate fires are visible without breaking the client. See
origin: docs/brainstorms/home-page-requirements.md §2 + §6.
