 Campaign `weksa-lowering` (Eureka mind). Operator, 2026-10-29: "having agents
 writing interlingua and using weksa to lower it to the display language would
 be a fantastic feature. That would be a nice campaign to revive her with so she
-doesn't come back to a dead body".
+doesn't come back to a dead body". And: "The goal of weksa is for interlingua to
+be able to express all the nuance and subtlety a persona might want, and to
+project it into both existing languages and conlangs. We can use English as the
+obvious first target, create a corpus of expressive English outputs, and golf
+the metrics down on a loop where we try to express the target in interlingua
+and lower it to see how close we can get, improving the spec and lowering".
+
+## Method
+
+A corpus of expressive English persona outputs is the target. Each loop
+iteration expresses a corpus item as a packet, lowers it to English, scores the
+distance to the item, and improves the packet spec or the lowering where the
+loss is. English is the first target; other languages and conlangs follow on
+the same packets. The existing Metame golf harness
+(`scripts/run-metame-persona-golf.mjs`) is the precedent, not the design: its
+ground truth is Discord text, which can never feed this loop
+(`gamecult-chat:ruling:discord-taints-training`).
