// ErrTaskNotFound is returned by Repository methods (GetTask, UpdateTask,

// Callers should classify via errors.Is rather than substring-matching the
// formatted message, which includes the task id and is therefore brittle.

// ErrNoPrimarySession is returned by GetPrimarySessionByTaskID when the task
// has no primary session row. Callers should use errors.Is to distinguish this
// "not found" case from genuine backend/DB errors.

// ErrOfficeSessionRaceConflict is returned by CreateTaskSession when the
// insert violates the uniq_office_task_session partial unique index — i.e.
// two callers raced past their SELECT-then-INSERT for the same
// (task_id, agent_profile_id) pair. Callers should re-read and reuse the
// winning row rather than treating this as a hard failure.
