Status: IN
Time injection enables fully deterministic testing by making wall-clock time an explicit parameter across notification, rate limiting, and crawling — unless the inconsistent fallback defaults (rate limiter falls back to `time.time()` while chat defaults to `0.0`) mean that tests omitting the time parameter exercise fundamentally different behavior depending on which module's convention they inherit.
Time injection is sound but inconsistent defaults create divergent untested fallback behavior
