# Provider acknowledgement and correction status

Update recorded for the article revision on 24 September 2026.

## Source and date

This note records the email from Qalb supplied for this revision on 24 September 2026. The original message headers and sending timestamp were not supplied; 24 September is the revision date, not a verified email sending date. The acknowledgement and expected correction timing are provider statements. No new market-data acquisition or independent verification of corrected records was performed for this update.

## What the provider confirmed

[Assymetrix](https://data.assymetrix.com/api) reports having reviewed the evidence bundle, market and trade identifiers, query windows, both Kalshi comparisons, the Polymarket records and the September 9 recheck notes. It confirms that the reported discrepancies originated in its data rather than a misreading of its interface.

The response states that corrections are underway but will not be available before the planned article publication. Corrected Polymarket records are expected during October 2026, with Kalshi records following. Exact dates remain unconfirmed. The provider says it will supply those dates and corrected rows for the windows in the evidence packet.

The response does not specify the precise technical cause, full affected population, corrected dataset version or completed backfill. It is not independent proof that any corrected record is already available.

## Effect on the article

The trade-data discussion now distinguishes acknowledged provider-side discrepancies from pending corrections. The numerical comparisons continue to describe the saved September 7–9 captures. The affected trade fields remain unqualified for complete-volume or execution-return claims until corrected records are received and checked.

The Miami weather reconstruction, native payout comparisons, historical-rule qualifications and limits on estimating disagreement prevalence remain unchanged. The provider acknowledgement concerns the trade-record cases; it does not establish which weather-source record a venue used for settlement.

Once corrected rows are supplied, the same fixed market/trade IDs and query windows will be compared again. Any resulting change will be recorded in a separately dated update, preserving the original evidence.

## Retained evidence

The earlier provider recheck and receipt evidence retain their original dates and contents. The article evidence bundle includes this new status note separately from those historical records. The supporting-evidence handoff prepared on 16 September remains an account of the original observations, not a claim about the availability of corrected data on a later date.
