Quant Data Layer v2.0.14

Certified Patch Scope

v2.0.14 repairs an exact durable-replay optimization in the stable V2
projector. When a canonical Kafka record is already byte-identical and durable,
the projector skips a duplicate canonical sink write while retaining lineage and
idempotent compatibility-cache projection. It also corrects the release
acceptance client so its quiet-trade request exactly matches the governed
manifest entitlement.

This patch inherits the v2.0.13 certificate. Its bounded, real V2 no-order
acceptance verifies the changed runtime through two query replicas and two
stream aliases for:

  • Binance USD-M BTCUSDT and ETHUSDT.
  • OKX Swap BTC-USDT-SWAP and ETH-USDT-SWAP.
  • Five closed 1m BAR warmup rows plus authoritative TRADE, durable cursor ACK
    and contiguous reconnect/resume for every case.

The disposable client made no provider-direct connection and no order, signal
or sizing action. This is a single-host data-plane patch certification, not a
broker execution, independent HA/DR or VN market-hours certificate.
