Backfill path

The backfill path starts from Polymarket Gamma active and closed events, hydrates missing fields from CLOB by slug or condition id, and supplements missed markets from Polygon exchange registry events.

Live path

The live path keeps moving forward with checkpointed market discovery, overlapping block scans, and a shared safe high-water block for market, oracle, and trade sync.
