Struct FrozenConfig 

pub struct FrozenConfig {
    pub clock_stamp: ClockStampGranularity,
    pub clock_zones: Vec<ClockZone>,
    pub sandbox: SandboxLimits,

}

Frozen at Run start, never re-read within the Run. Fields only grow.

Fields

clock_stamp: ClockStampGranularity

clock_zones: Vec<ClockZone>

sandbox: SandboxLimits

Frozen for the same reason the tool table is: what a run may reach decides what it was told it could do, and a capability that widens mid-run is one nobody reviewed.

mcp: Vec<McpServer>

External tool servers, frozen for the same reason as the tool table itself: their tools enter the catalog at run start, a provider hashes that array ahead of the system prompt, and a table that widened mid-run would both discard the cache and hand the model a capability nobody reviewed.

effort: Option<Effort>

How hard the model may think. Frozen rather than live because the provider renders it into the cached prompt prefix: changing the effort value mid-run invalidates the message cache breakpoints, so a run that could retune itself would keep paying to rebuild the cache it just discarded. A change applies to the next run.

second_threshold: Option<SecondThreshold>

Where the context reminder’s second rung sits. None when no layer states one: the rung falls back to consts_policy::CTX_REMINDER_SECOND_DEFAULT where it is read. Frozen with the run: a rung that moved mid-run would make “each rung sounds once per run” depend on when somebody edited a file.

search: SearchConfiguration

Which supplier web_search reaches, frozen for the reason mcp is: the tool and its parameters enter the catalog at run start, and a supplier changed mid-run would change who receives the run’s queries without anybody reviewing it. Absent in a snapshot written before search existed, which reads as Default.
