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.

Add a real TurnExecutor (behind the `provider` feature) that runs each
topology turn as a single tool-free LLM call via any cm-llm provider
(Anthropic / OpenAI-compat / scripted). Topologies now execute real model
calls and produce real metrics (tokens), feeding the comparison harness.
- ProviderExecutor builds a per-role system prompt + threads upstream context
into the user message; collects TextDelta → output, Usage → tokens.
- Tool-free reasoning turns take no sandbox-leaving actions (gated = []); §15
remains satisfied. Tool-using turns will route through a cm-runtime adapter.
- Core crate stays dependency-light; cm-llm/futures are optional (feature).
- Tests: pipeline + hierarchical run over the deterministic scripted provider
(7 tests with --features provider). Clippy clean.
