A sharp position change on three systems within 36 hours, now cross-verified. Interpretation: this reads as a citation-gravity event rather than a market verdict. The citation cluster driving the change is two pieces of third-party content published in the past week, which makes a measured editorial response viable inside a 7–10 day window.
Between 25 May 18:00 and 27 May 06:00, three monitored systems independently demoted Kepler from second to sixth position on the seed prompt. The displacement is correlated with two newly indexed comparison articles ranking three competitors above Kepler on "ease of implementation."
A G2 category report (published 22 May) and a practitioner blog post (published 24 May) are cited in 27 of 40 monitored responses describing the new ranking. Both articles describe Kepler as "powerful but harder to roll out than newer alternatives."
Gemini still ranks Kepler second. The lag is consistent with Gemini's slower indexing cadence on third-party comparison content and is expected to reconcile within 3–7 days.
This reads as a citation-driven position change rather than a market verdict. The two articles cited by three systems are reachable, the publishers are reachable, and the framing they introduced ("harder to roll out") is correctable with published evidence. The 7–10 day window before Gemini reconciles is the window in which counter-evidence is most efficiently placed. If no counter-content lands in that window, the framing is likely to settle across all four systems by mid-June.
