Keep local state consistent
Numeric values are serialized as strings. Live messages include sequence, stream_id,
and server_ts_ms; book.hash summarizes a book payload.
- Build local state from a full
booksnapshot. - Apply incremental messages in sequence.
- On reconnect, stream change, or sequence gap, discard the local book and request a fresh snapshot.
Do not continue applying deltas after a missed sequence. A visually plausible but stale book can produce incorrect prices and unsafe orders.
