Continuous Event Evidence · v0.1.44

Replay the sequence.
Never fill the gap.

DEAL journals public BTC/USD WebSocket frames into immutable evidence segments, reconstructs venue-local books from documented update semantics, and records continuity failures instead of silently guessing missing state.

139,733 indexed frames 632 evidence segments 4,593 book checkpoints 0 recorded gaps
Current continuous state

Venue-local reconstructed books

A reconnect begins a new evidence session. A sequence failure ends continuity. DEAL never merges those boundaries away.

Positive book flow means bid additions / ask removals dominated visible change. Negative means ask additions / bid removals dominated. It is a DEAL-defined statistic, not trader intent.

Transient liquidity0

A transient add/remove episode is not proof of spoofing. A sweep cluster can contain multiple takers. Absorption is a deterministic pattern test, not proof of hidden liquidity.

SESSION BOUNDED

Permanent boundary

CONTINUITY IS EVIDENCE.

When a provider documents update identifiers, DEAL verifies them. When the sequence skips, the local book is invalidated and the next connection must establish a fresh snapshot. Missing events are not reconstructed from price action, interpolation or model inference.
