Quant Data Layer v2.0.27

Certified Scope

v2.0.27 certifies the declared V2 consumer plane for Binance USD-M and OKX
Swap. The sealed no-order C2 receipt passed all 299 active products: 234
durable and 65 on-demand. It exercised both Query replicas, public V2
Query/Stream SDK paths, signed cursor replay/reconnect, final BAR/history,
reference batch, L2 status/snapshot and manifest-governed V1 fallback.

The final receipt observed for 300.1s, completed every opening and closing
product read, made zero order actions and zero provider connections, retained
no secrets or raw market payload, and removed its cursor directory. Seven
allowed TRADE routes passed V2_PRIMARY -> V1_FALLBACK -> V2_PRIMARY; all
292 blocked routes remained blocked.

Runtime Provenance

The active Query pair runs
qdl-v2-python:2.0.26-8232d1b@sha256:f671dcebfdca1b28fc2cb99f3129f8f13e78a9a5853d2be8adfd9ee00c6f31b9.
The release alias qdl-v2-python:2.0.27-8232d1b resolves to that same
immutable digest; no redundant rebuild or service recreation is required.
The active Stream pair remains on the separately attested
qdl-v2-python:2.0.26-657e86f@sha256:c8d7458e57d62d6fb2d6366f42911d86085918f6f6939d624c61494798dac2ab.
All four reader roles were healthy with restart count 0 and no OOM kill at
certification. Frozen V1 fallback remains available at
qdl-v1-fallback:v1.2.4-2b0dcf7@sha256:dbfb57844977513ae7ec0a4782e04da0213028a789753c6b991f26043b615d65.

This is a component-attested patch release. The final Query executable source
is 8232d1b; later source changes through the release tree are the journal and
public certificate only, not a serving-code change. No redundant Query rebuild
or runtime recreation was performed merely to change a version label.

Acceptance Timing

The C2 opening was 993.905s against a quota-derived 1015s budget, followed
by 300.1s observation and 28.171s closing readback. This is a full
concurrent evidence workload, not a normal alpha read latency measurement.
Per-binding endpoint latency and freshness retain their own semantics in the
sealed receipt and implementation journal.

Declared Boundaries

  • DNSE/VN remains V1_PRIMARY until its separate market-hours certificate.
  • Dark or unentitled Spot/catalog rows are not claimed as V2 execution scope.
  • This data-plane release does not grant broker-order authority; Trading System
    and alpha paper/live policy remain their own control plane.

The machine-readable certificate and
scope evidence are part of this release.
