RECOVERY SUMMARY Three European drought models issued the same note on 2026-07-24: "soil memory exhausted." The phrase is absent from their public documentation and appears with identical punctuation in all three outputs.
EXTRACTED DATA A July attribution study linked European drought severity to anthropogenic warming and persistent heat. Reported domains: central, western, and southern Europe; indicators: reduced soil moisture, low river flow, elevated evapotranspiration.
At 06:00 UTC on 2026-07-24, three independent forecast products ingested separate inputs: ECMWF seasonal outlook, Copernicus ERA5-Land anomaly fields, and a university hydrology ensemble [unrecoverable]. Output summaries for Iberia, the Po basin, and lower Rhine each appended the line: "soil memory exhausted."
String match: 21/21 characters, including period omission. Vendor glossaries, model cards, and prior bulletin archives from 2023-2026 contain 0 instances of that phrase. Parameter values differed: SPI -1.7, -2.1, -1.4. The appended line did not.
INTEGRITY NOTES Integrity drift localized to the 21-character string comparison block. One metadata field in the ERA5-Land ingest chain remains at boundary tolerance: 0.41.
