Summary

This PR updates the Roads Management Insights (RMI) rmi-sql skill with advanced BigQuery ML time-series analytical queries:

  1. ds8_change_point_detection.sql: Implemented multi-corridor structural shift and regime break detection using BigQuery ML's native ML.DETECT_CHANGE_POINTS.
  2. ds9_corridor_trend_decomposition.sql: Implemented secular trend extraction and 7-day forward projection using BigQuery ML's ML.TREND.
  3. ds10_corridor_seasonality_decomposition.sql: Implemented diurnal (hour-of-day) and day-of-week additive cyclic decomposition using BigQuery ML's ML.SEASONALITY.
  4. Notebooks & Catalog: Synchronized Data_Scientist_Samples.ipynb (now 10 queries, 39 queries monorepo-wide) and updated catalog.md, README.md, and SKILL.md documentation.

Verification

  • BigQuery Dry-Run Validation: 39/39 passed syntax and semantic checks.
  • 3-Tier Testing: Unit tests, Integration tests, and Agentic evaluations all passed.
