Enum HostReaction 

pub enum HostReaction {
    DoNotRetry,
    NarrowOrSkip,
    RaiseBudgetOrSkip,
    RetryWithBackoff,
    Respawn,
    DropProvider,
    ReportAndCount,
}

What a host should do about a provider error. Advisory guidance attached to each ErrorCode, so the reaction lives with the vocabulary rather than being re-derived by every host.

Variants

DoNotRetry

The request itself was wrong. Retrying it unchanged will fail again.

NarrowOrSkip

The provider does not serve exactly what was asked for. Adjust the request — narrow the query’s kinds, or downgrade representation_preferences to full — or stop querying this provider for it.

RaiseBudgetOrSkip

No useful frame fits the stated budget. Raise max_tokens or skip.

RetryWithBackoff

Transient. Retry with backoff.

Respawn

The provider is tearing down. Re-spawn it or drop it from the fan-out.

DropProvider

The provider is permanently unusable — e.g. a handshake version family that shares no major with the host (SPEC.md §H3). Drop it from the fan-out; retrying cannot help, and it is not a health blip to count and keep. Distinct from DoNotRetry (there the request was wrong) and Respawn (there a retry could succeed).

ReportAndCount

A provider fault. Report it and count it against the provider’s health.
