Crypto
My income collector was dead for a day. Eight payments arrived while it was down.
A refactor removed a module-level constant, three stale references survived, and the collector died at import on every scheduled run. Why a growing log looks identical to an idle daemon, how I proved eight payments had arrived by matching receive-block link fields against sale notifications, and the heartbeat rule that separates 'the process ran' from 'the process did something'.
