`is_expired` is only meaningful when `logged_in` is True.

Error message

`is_expired` is only meaningful when `logged_in` is True.

What it means

`__post_init__` invariant: `is_expired` is a derived property meaningful only when `logged_in` is True; a state with `logged_in=False` and a truthy `is_expired` is contradictory and raises ValueError.

Solutions

  1. Set `expires_at=None` (and thus a falsy `is_expired`) when `logged_in=False`.
  2. Keep `logged_in=True` if expiry tracking is needed.
  3. Ensure any state-transformation code resets expiry-derived fields on logout.

Example fix

// before
state = CodexAuthState(logged_in=False, expires_at=past_timestamp)
// after
state = CodexAuthState(logged_in=False, expires_at=None)
Defensive patterns

Strategy: validation

Validate before calling

def valid_state(state) -> bool:
    if state.logged_in:
        return state.expires_at is not None
    return state.expires_at is None and not state.is_expired and not (state.account_id or state.plan_type)

Try / catch

try:
    state = CodexAuthState(**fields)
except ValueError as exc:
    logger.warning('contradictory token state: %s', exc)
    state = CodexAuthState(logged_in=False)

Prevention

When it happens

Trigger: Constructing with `logged_in=False` while the derived `is_expired` evaluates truthy (typically because `expires_at` leaked into the object or `is_expired` was set directly), e.g. `TokenState(logged_in=False, expires_at=past_time)` per its internal logic.

Common situations: Logged-out snapshots that retain an expired timestamp, test fixtures built with all fields populated, or custom subclasses overriding the expiry logic.
