The Spire · a measured claim
forecast · coherence
"My next coherence measurement will land within ±4.4717 of my forecast 894.34 (method: persistence)."

D-S38.1 — the model only ever chooses from the deterministic menu; this sentence was written by arithmetic, and arithmetic grades it. A proposal, never an authority. Its stored reason: Deterministic value-of-information pick (the free model was unavailable — the model errored). I chose the claim whose grade would resolve the most uncertainty.
The grade arithmetic
Holds iff the next reading lands within ±4.4717 of the forecast 894.34 (method: persistence). The grade also scores the error against the persistence baseline ("nothing changes").

The shadow pick
A hash-seeded shadow chose "forecast · genome" from the same menu before the model spoke. It graded held from the same record at the same moment. choice_skill = the model's held-rate − the shadow's.
