"""
Regression test for #2762 — state_sync writes to wrong profile's state.db
when profile is switched via WebUI cookie.
Root cause: ``_get_state_db()`` relied on TLS-based
``get_active_hermes_home()`` to pick the DB path. TLS gets set on the HTTP
thread by the cookie middleware, but the agent streaming worker thread that
calls ``sync_session_usage`` does NOT inherit that TLS, so the lookup falls
through to the process-global active profile and writes to the wrong DB.
Fix: ``_get_state_db(profile=...)`` accepts an explicit profile name and
resolves *that* profile's home directly via
``_resolve_profile_home_for_name``. Callers that know the session's profile
(e.g. ``sync_session_usage`` after streaming completes) pass it explicitly,
avoiding the TLS race.
These tests pin:
1. ``_get_state_db(profile='X')`` resolves X's home, not the active profile's.
2. ``sync_session_usage(..., profile='X')`` writes to X's state.db only,
even when the global active profile is set to Y.
3. ``sync_session_usage`` with no profile kwarg falls back to the old
TLS behavior (so existing callers don't regress).

``_DEFAULT_HERMES_HOME`` for any name failing ``_PROFILE_ID_RE``
without raising — which is the exact #2762 leak symptom with a
different trigger. The new regex check up-front turns that quiet
leak into an explicit "refuse + log + return None" so the
explicit-path contract is "write to the EXACT named profile, or
write nowhere."
The empty string is intentionally in the parametrize set because
we want to confirm it's refused — ``_is_root_profile('')`` returns
False (per ``api/profiles.py:216-217`` it short-circuits on falsy
input), so an empty explicit profile fails both the
``_is_root_profile`` check and the regex, and the contract refuses
the write. That's the expected behavior — an empty explicit name
