Polygon L1 regimeLive · since 2026-05-05

Chain backtest certified MEDIUM on canonical Polygon events. Polygon L1 regime is read by the Invarians stress-events detector since 2026-05-05 and feeds the live operational scope (events tracked when Polygon leaves S1D1, composite L1×L1 ETH×POL active when both Ethereum and Polygon stress simultaneously).

Reproduction steps

  1. Open the BigQuery console on a project with the free monthly quota.
  2. Paste the content of extract_pol.sql, run the query.
  3. Export the result as pol_invariants_2020_2023_phi720.csv.
  4. Clone github.com/agentnorthstar/calibration.
  5. Place the CSV in scripts/, run python scripts/backtest_pol_phi720.py.
  6. Confront the output to expected_thresholds.md.
Polygon L1 is integrated to the stress-events detector since 2026-05-05, contributing to the live operational scope alongside Ethereum L1 and the L2 rollups. Internal calibration parameters (nominal construction, divergence thresholds) are embedded in backtest_pol_phi720.py at runtime and are not exposed publicly. Reproducers confront the output (TPR, FPR, M1, per-window states), not the parameters.
