Figure 4. The two-lane operating pattern: (1) Every request flows left to right through the online lane in under 40 ms; (2-3) a nightly offline lane samples served decisions, adjudicates them against reviewed truth, and re-evaluates; (4) distilled rules are promoted back into the live decision funnel by content-addressed swap. The masking invariant holds on both lanes.
