Function WithClock

pkg/session/session.go:891–895

WithClock injects the time source used for the session's CreatedAt, for timestamping messages it generates (summaries, compaction input), and for messages added through WithUserMessage/WithSystemMessage/ WithImplicitUserMessage. Because those message options read the clock when they run, WithClock m

(now func() time.Time)

// ordering). Primarily for tests that need a deterministic clock; production
// code leaves it unset and falls back to time.Now.
func WithClock(now func() time.Time) Opt {
	return func(s *Session) {
		s.clock = now
	}
}

// WithIDGen injects the generator used to mint the session ID when no explicit
// ID is provided. Primarily for tests that need deterministic IDs; production
