  "abstract": "Operational announcements are often used as if they were synchronized records of market access. This paper separates announcement evidence from observed transfer status in two public, redacted datasets. Dataset A contains 996 labels across a 20-venue target map for 2026-04-23 to 2026-10-20, with explicit coverage gaps and separate publication and effective-time fields. Dataset B audits 502 polling rounds at four venues over a 169.1-hour log span. Among 929 auditable non-Gate key-transition records, 503 had no contemporaneous semantic announcement match; this record-level proportion is concentrated at LBank and is not an independent-event rate. For 81 matched announcement events, median detection-minus-publication lag is +5.81 minutes, with venue-specific signs and sensitivity bounds. The median of 517 continuously observed closed withdrawal intervals is 0.648 hours, but batch exclusions move it materially. The release supplies explicit estimands, gap-aware duration partitions, reproducible tables and figures, and evidence boundaries for research on operational information without claiming execution, profitability, or market-impact effects.",
