Response frame sent from the daemon back to a client.

Fields

ok: bool

result: Option<String>

error: Option<String>

namespace_mismatch: bool

config_mismatch: bool

Set when the request’s config_id does not match the daemon’s. Like namespace_mismatch, this signals the client to fall back to local dispatch rather than execute under a different runtime/config.

served_config_id: Option<String>

The config_id the daemon dispatched under, echoed back so the client can positively confirm the result came from a matching runtime. A pre-config_id daemon omits this field (deserializes to None), which the client treats as a mismatch and falls back to local dispatch — this closes the upgrade window where a new restricted client could otherwise trust a still-warm legacy daemon’s broader registry.

version_mismatch: bool

Set when the client’s protocol_version does not match the daemon’s PROTOCOL_VERSION. The client must treat this as a hard error and surface the human-readable error field rather than falling back to local dispatch (which would hide the version skew).

daemon_protocol_version: u32

The daemon’s PROTOCOL_VERSION, echoed in error responses so the client can include both sides in the diagnostic message. Pre-versioning daemons omit this field (deserializes to 0).

metrics: Option<MetricsSnapshot>

Populated when the request set metrics_only: true: a point-in-time snapshot of the daemon’s server-side gauges. None on every other response, and on any response from a daemon that predates this field (client-side back-compat via #[serde(default)], matching served_config_id’s upgrade-window handling above).

request_id: Option<u64>

Echo of the request’s request_id (khive#948), present whenever the frame that produced this response carried one — including on every error/denied arm, not only success, so a client can join a failure the same way it joins a success. #[serde(default)] so an older daemon’s response (predating this field) deserializes to None rather than a parse error.
