Step 1 of 3
Circuit-breakers: block bad data at the boundarya blocking check on each promotion boundary
An alert that fires after corrupt data reached the gold serving layer arrives as a postmortem. The higher-impact pattern is a circuit-breaker: a blocking quality check on each promotion boundary, drawn here at bronze to silver. When the check fails, the bad partition does not promote.
Interactive diagram. Step through it with the Next and Previous controls below, or Tab to a region to read its detail.
The quality gate is drawn at the bronze→silver boundary, and the same check repeats at silver→gold. Fail it and the bad partition never promotes.
