Judge spend gained provider, model and mission on 2026-09-14; agent spend —
the larger half — did not. The runtime's `done` frame has always carried
`model` and `provider` beside the two token counts, and `topology_exec` read
only the counts, summed them, and charged the sum as output with no record of
which provider served the turn.
`TurnOutcome` and `StepRecord` carry a `Spend` now (input/output split,
provider, model), the worker passes it through `cm_billing::charge` along with
the mission id, and the chat runtime records the model it requested — that
loop drives one provider with no chain, so requested is answered. A bare
model name is recorded without a guessed family. `StepRecord.spend` is
`serde(default)` so journaled checkpoints from before this field still load,
and `tokens` stays as the total every reader keys on.
`charge` moved from `query!` to `query`: the macro pins the statement to
offline metadata that a schema change then has to regenerate against a live
database, for columns that are nullable text and uuid.
The done-frame test now asserts the split and the provider survive, not just
the sum.
