Abstract157 words

Publication time, stated effectiveness, and observed status are different clocks.

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.

公告发布时间、公告正文所述生效时间、公开可见性、真实状态翻转和轮询检测并不是同一个时刻。数据集 A 覆盖 2026 年 4 月 23 日至 10 月 20 日(UTC),首尾相隔 180 天、含两端共 181 个自然日;目标地图含 20 家场所,共 996 条公告标签;11 家存在可观测来源,其中 Pacifica 为零事件,另 9 家存在覆盖缺口。数据集 B 对 Bitget、KuCoin、Gate 和 LBank 的公开无密钥状态接口进行对照,日志含 502 轮、跨度 169.1 小时,并存在约 13.2 小时已知缺口。

720 条具有秒级生效时间的公告中,正文生效时间减发布时间的中位数为 46.98 小时。在三家可判定的非 Gate 场所中,503/929 条键级状态迁移记录属于 Q1,描述性比例为 54.14%,其中 LBank 提供 398 条,故该比例不是独立真实事件发生率。81 个唯一 Q3 公告事件的公告—检测时差中位数为 +5.81 分钟;上下界替代后的中位数敏感性包络为 +5.43 至 +14.89 分钟。517 个连续闭合提现区间的中位时长为 0.648 小时,剔除所有同起点八条及以上批次后仅余 75 条,中位数变为 5.028 小时。

研究使用固定时间子样本、场所留一、检测上下界、极端追认排除及 AMPL、GRAM、ERC20 和大批次排除进行描述性稳健性检查。本文没有预测目标、收益模型或交易规则,因此样本外预测、Diebold–Mariano 检验、多模型数据窥探调整和扣除完整成本后的经济显著性均不适用。复现包可从公开标签与派生 JSON 重算结果,但不能重建未公开的历史原始日志,也不能提供第二标注人一致性。本文仅发布结构化标签、公开 URL 和派生审计数据,不发布公告全文、私密注记、用户数据或未公开接口。本文为未同行评审的研究预印本,不构成投资建议。

Paper contents

I · Research question

What can public labels and polling establish without inventing synchronization?

An announcement about a delisting, network upgrade, or transfer suspension has at least two times: when it was published and when its text says an operational change should occur. Independent polling supplies a third time: when a public interface was first detected in a corresponding state. None is automatically a direct observation of the real operational flip.

The paper therefore asks a descriptive question rather than a return-prediction question: what can a carefully documented announcement label set and a short public-status polling study establish about coverage, timing, and observability? Missing coverage is coded as a gap, not a zero. An unmatched transition is not proof that no announcement existed anywhere.

Research 01 and 02 measure and frame net carry. Research 07 adds the operational-event, announcement-time, and transfer-status observation layer; it does not validate their return estimates.

II · Data & method

Separate the record, the event, the key, and the interval.

Dataset A covers 2026-04-23 through 2026-10-20 UTC: 180 elapsed days, or 181 calendar dates when both endpoints are included. Its 20-venue target map contains 996 labels from ten venues with nonzero events, an observable zero at Pacifica, and nine venues with full-window or historical gaps. Publication and effective times remain separate; 253 null effective times are not imputed.

Dataset B contains 502 polling rounds at Bitget, KuCoin, Gate, and LBank over a 169.1-hour log span. A known gap of approximately 13.2 hours and other observational limits remain explicit. Q1, Q2, Q3, and duration use different denominators and are never pooled as if they were interchangeable.

Source and coverage map

Semantic event deduplication, rescheduling links, separate timestamp granularities, and an explicit distinction between observable zero and unavailable history.

996 announcement rows
II

Q1 · unmatched detected transition

A key-by-transition record has no semantically corresponding contemporaneous announcement in the saved auditable snapshot range. It is not an independent-event count.

503 / 929 records
III

Q2 and Q3 · strict evidence and timing

Q2 requires observable keys, due execution, sufficient polling, and a contrary state. Q3 compares detection with publication on unique matched announcement events.

81 Q3 events · 420 keys
IV

Gap-aware duration

Continuous closures, gap-crossing endpoint pairs, right-censored records, and openings without an observed stop remain separate partitions.

517 / 21 / 72 / 98

A negative Q3 lag is not a proven flip order.

It means that the recorded detection preceded the announcement publication timestamp. The actual operational flip is usually latent between polls, and nominal source time is not always proof of first public visibility.

III · Results

Coverage, timing, and batch dependence—shown at record level.

IV · Robustness & evaluation boundary

Robustness means exposing composition—not manufacturing a confidence interval.

Fixed time subsamples, venue leave-one-out rules, lower and upper detection bounds, extreme-retrospective exclusions, and AMPL, GRAM, ERC20, and large-batch exclusions test whether descriptive summaries depend on a particular record mix. They do not convert venue-clustered, batched, nonrandom observations into independent draws.

Announcement lead

The 720-pair median is 46.98 hours. Early and late medians are 45.70 and 47.83 hours; venue exclusions range from 41.48 to 58.00 hours in the reported leave-one-out set.

Q1 composition

The pooled 54.14% is highly concentrated: LBank supplies 398 of 503 Q1 records. Removing Bitget, KuCoin, or LBank changes the denominator as well as the numerator.

Q3 bounds

The recorded median is +5.81 minutes. Lower- and upper-bound substitutions give a deterministic median envelope of +5.43 to +14.89 minutes—not a 95% confidence interval.

Duration batches

Excluding LBank ERC20 changes the median from 0.648 to 0.915 hours; excluding all same-start batches of eight or more leaves 75 intervals and a 5.028-hour median.

Not applicable

There is no forecast target, return model, trading rule, or model search. Diebold–Mariano tests, out-of-sample forecast evaluation, full-cost economic significance, and multiple-model corrections are therefore not applicable.

V · Evidence boundaries

No claim of execution, causality, complete coverage, or trading performance.

Not execution or causality

A publication timestamp is not an execution timestamp, and a detected status change is not proof of the latent operational flip or its cause.

Not complete coverage

Missing announcements remain gaps. Q1 means no contemporaneous semantic match in the audited surface—not that no announcement existed anywhere.

Not independent-event rates

Q1 uses key-transition records, Q3 uses announcement events, and duration uses observed close–open intervals. Their denominators cannot be converted into a universal venue rate.

Not trading evidence

The paper reports no return forecast, realized tradability, executable profit, market impact, venue ranking, or investment recommendation.

VI · Limitations & ethics

Unknown remains unknown.

  • Coverage is incomplete. Nine target venues have full-window or historical gaps. A gap is not zero, and Gate is not assigned a Q1/Q2 rate.
  • Annotation is single-person. An 88-item single-person review does not establish inter-annotator agreement or an independent error rate.
  • Polling detects rather than directly observes flips. Long gaps, round ordering, processing bounds, field oscillations, and many-to-many key mappings restrict interpretation.
  • Replication is bounded. Released data can regenerate all reported tables and figures, but cannot reconstruct unavailable raw historical logs or the earlier 90-day baseline.
  • Redistribution is intentionally limited. The public release contains labels, public URLs, and derived audit data—not announcement text, private notes, user data, nonpublic interfaces, or access-control circumvention.

Not investment advice. This paper is for research and methodological information only. It does not provide investment, legal, accounting, or tax advice; does not recommend any trade or leverage; and does not claim execution, profitability, or market-impact effects.

VII · Conclusion

An operational information layer with visible seams.

The release contributes a documented announcement dataset, an observation-first pairing framework, and a four-venue polling study whose gaps and counting units remain inspectable. Its central finding is methodological: publication time, text-stated effectiveness, detected status, and actual execution cannot be collapsed into one timestamp.

The data can support future research on operational information and market access. They cannot, by themselves, establish causal price effects, realized tradability, profitable execution, or universal venue rankings. Future predictive or trading studies must supply their own outcome definitions, temporal controls, cost models, and evaluation designs.
