No next occurrence is being forecast right now — this pattern has gone quiet and needs to keep recurring before we forecast it again.
Why: it has occurred on 6 days — every day we've been watching, usually around 23:40 UTC.
Defaxon forecasts when a recurring event is likely to happen again — its rhythm — not the outcome. For a sports fixture that means we flag that the match recurs, not who wins; for a flight, that the route runs, not whether it’s on time. It’s probabilistic early-warning, never prophecy, and it sharpens as the archive grows.
