Two related issues caught in live verification: 1. Coinbase's sequence_num is connection-global (not per-product). Previous per-product tracking flagged every cross-product frame as a gap. 2. Even after switching to global tracking, gaps still occur regularly under normal operation (Coinbase's exact sequencing pattern across channels is not strictly seq+1 frame-to-frame). Treating gaps as fatal kills the ReadLoop in seconds, never giving the minute aggregator a chance to cross a boundary, so btc_eth_minute stays empty. Resolution: rewrite Sequencer for a single global counter and downgrade gap-detection to a non-fatal Warn. ReadLoop continues; (symbol, ts) PK on btc_eth_ticks is the safety net for any duplicate replay. Includes a diagnostic log on loop exit (handleConn) for ops visibility. |
