Anomalies the detectors caught on the tape: spot tokens off their peg, perps discovering price into a sleeping reference, corporate actions a venue failed to apply, and gaps in our own capture — published against ourselves, because freshness claims are also measurable.
trades + funding streams silent for 20m41s (threshold 60s) — venue marked stale, never silently frozen.
hl perp keeps discovering price while the US reference is stale (closed session). Divergence is measured, not noise.
spot-backed token beyond its 75 bps depeg threshold. Redeemability is the claim; the tape disagrees.
CEX-listed token trading rich while the reference sleeps — weekend price discovery, recorded.
book stream 6m20s behind (threshold 60s); trades stream healthy. Depth metrics for bitget flagged stale.
spot-backed token trading at a discount beyond threshold — redemption arbitrage not closing the gap.
book stream gapped 4m during venue maintenance; backfilled.
reference executed a 4:1 reverse split; the backed token still prints at pre-split scale (0.25x the reference).
