Struct ProbeResponse 

pub struct ProbeResponse {
    pub body: ProbeResponseBody,
    pub slash_sig: Vec<u8>,
}

Node → client response on cdn/probe/v1 (ADR 005 §cdn/probe/v1).

This struct holds only the frozen base (ADR 013 §Tier 1): the signed ProbeResponseBody and the slash_sig covering it. Unsigned fields live in ProbeResponseExt, which travels as separate trailing bytes — see encode_probe_response / parse_probe_response_ext.

The split is what keeps a future unsigned field out of Tier 3. Postcard is positional and fills no defaults for absent trailing fields, so an Option<T> appended to this struct would fail to decode against an older sender that never wrote it; appended to the separately-decoded extension it costs no coordination at all.

slash_sig is mandatory and non-empty on the wire; requesters MUST reject missing/zero-length signatures (enforced via ProbeResponse::validate and the requester’s SLASH_SIG_LEN check).

Fields

body: ProbeResponseBody

Signed body. Its wire layout is frozen per ADR 013.

slash_sig: Vec<u8>

EIP-712 secp256k1 signature over the typed-data hash of body’s fields {hash, has_blob, rate_per_mb, timestamp_us} (ADR 014 §1; see decdn_incentive::ProbeSlashData). Always exactly SLASH_SIG_LEN bytes — not a signature over postcard bytes. The verify path rejects any other length.

Implementations

impl ProbeResponse

pub const fn validate(&self) -> Result<(), MessageValidationError>

Validate field invariants. The wire-decode path enforces the rate_per_mb bound automatically via deserialize_rate_per_mb; this method additionally enforces the requester-side mandatory-slash_sig rule (ADR 014 §1) and is exposed so construction sites can re-check before sending and tests can assert validity without a full encode/decode roundtrip.
