    "detail": "The Drift Sentinel continuously samples regime state across the registered Structural Frame, computing three drift vectors at each cycle: ΔM (magnitude — total displacement from nominal), ΔD (direction — angular deviation of migration trajectory), and ΔV (velocity — rate of displacement). When any vector exceeds its configured threshold, the Sentinel emits a collapse-precursor alert to the S3 Spine bus. All readings are time-stamped for the TEMPORAL_REGIME_SEQUENCER. The Drift Sentinel is also the primary consumer of the Expectations module's nominal trajectory envelopes and the Atmosphere module's environmental pressure signals."
