Problem
Probabilities every night for six leagues, flowing unattended to a live site.
The site reads the prediction table directly, so a pipeline that fails silently is a user-facing outage nobody notices.
Decision
One scheduler container whose every run leaves a row, with three layers watching for silence.
Fixtures, expected-goals and odds data are ingested nightly; rating and form features feed a gradient-boosted match-winner model. Every scheduled run writes an audit row; a watchdog reads the rows, alerts are written in plain language, and an external dead-man check fires if the scheduler itself goes quiet.
Result
15,728 picks graded in public at a 52.8% hit rate, matching the 52.8% average stated probability.
