Jev versus text-generating models
Jev does not generate free-form text. A side-by-side video compares parallel decision-making with token-by-token text generation.

Jev performs a scope check on every code turn, flags hunks the prompt did not ask for, judges per hunk rather than whole PR, and offers In scope / Check scope / N unrequested options. Sessions only for now.
scope check on every code turn Jev flags hunks the prompt did not ask for → chip under the reply: In scope / Check scope / N unrequested → hover lists each flagged file + hunk judged per hunk, not the whole PR → sessions only for now
