Struct CallShape 

pub struct CallShape {
    pub model: String,
    pub max_tokens: Option<Ceiling>,
    pub effort: Option<Effort>,
    pub context_tokens: u64,
}

Which model this run calls, how much it may say, and how hard it may think — the frozen [model] config section as the turn sees it. effort comes from kernel::FrozenConfig and cannot change within the run: the provider renders it into the cached prompt prefix.

Fields

model: String

max_tokens: Option<Ceiling>

The model’s own ceiling, from the endpoint book. None when no catalogue row states one: the request then carries no ceiling and the wire that requires one refuses the call.

effort: Option<Effort>

context_tokens: u64

The model’s window, from the endpoint book. Zero when the book does not say, in which case the context reminder stays silent.

Implementations

impl CallShape

pub fn verified_against(&self, frozen: &CallShape) -> Result<(), AxError>

Refuses a shape that differs from the one a session froze.

The model, its output ceiling and its effort are the fields that reach the provider’s wire; changing any of them mid-session invalidates the message cache breakpoints the frozen prefix is paid for, which is why they freeze with the session rather than with a form. context_tokens is not one of them: it sizes this machine’s own reminder and never leaves it.

This is the runtime’s half of the interception the dispatch face owes: Command::Dispatch { effort } writes a room’s effort, and whoever lets that write through asks here first.

Errors

ConfigInvalid, naming the field that moved and the two ways out.
