-- 029_memory_dream_usage.sql — per-(date, owner) circuit-breaker counters
-- for the dream worker (feature 020 follow-up). Each row accumulates
-- daily token and job consumption so the ConsolidatorWorker can refuse
-- to dispatch further jobs once a threshold is hit. Rows are keyed by
-- UTC date (YYYY-MM-DD); the circuit naturally resets at midnight UTC
-- when Today() begins reading from a fresh row.
