Enum Decision 

pub enum Decision {
    ModelResponse,
    ModelSilent,
    FailClosedNoAction,
    FailClosedActionError,
    FailClosedLlmError,
}

How this speaker arrived at what it did (or did not) put on the wire.

The point of this enum is that “the model declined to join the election” and “the model could not be reached” produce identical bytes — none — and must never be identical in the log. That collapse is the OAuth2 failure the root CLAUDE.md records; here it would hide a total backend outage as protocol-correct quiet, indefinitely, because a silent HSRP speaker is completely normal.

Variants

ModelResponse

The model advertised. Bytes went out.

ModelSilent

The model chose no_advertisement: it looked at the election and stayed out of it. A deliberate answer, and the safe one.

FailClosedNoAction

The model returned no usable action at all.

FailClosedActionError

The model produced actions but none of them encoded — a bad state name, a priority that does not fit v1’s single byte, an MD5 TLV that cannot be generated.

FailClosedLlmError

The LLM call itself failed — outage, overload, unusable output.

Implementations

impl Decision

pub fn as_str(&self) -> &'static str

Stable, grep-able token. An operator looking for advertisements the model did not actually authorise greps decision=fail_closed_.

There is deliberately no model_reject token here, unlike radius. RADIUS can distinguish a refusal from silence because it has an Access-Reject packet to send. HSRP has no negative message of any kind: the only way a speaker declines to participate is by not advertising. So “the model refused” and “the model chose to stay out” are the same act, and model_silent is it. What must stay distinguishable — and does — is that act versus every fail_closed_*.

pub fn is_fail_closed(&self) -> bool

True when the server, not the model, chose to say nothing.
