Struct Describe 

pub struct Describe {
    pub name: String,
    pub link_namespace: String,
    pub fetch_style: FetchStyle,
    pub auth_realm: Option<String>,
    pub protocol: u32,
}

What a plugin declares about itself.

Fields

name: String

Plugin name (local-recordings, graph).

link_namespace: String

The link namespace this source’s citations carry (recording, graph). Recorded into sources.ron at install; collision-checked.

fetch_style: FetchStyle

auth_realm: Option<String>

FALLBACK credentials realm; prefer config_auth_realm (derived from validated configuration — tenant/client — so unrelated tenants never share a token). None = no auth (local sources).

protocol: u32

Plugin protocol version (ADR 0001). v1 = typed items + engine-owned checkpoints — the first externally observable wire contract; earlier in-process trait shapes are implementation history, not versions. The engine refuses to fetch from a plugin declaring any version other than PROTOCOL, and the field is REQUIRED on the wire: no plugin protocol has ever shipped besides the current one, so a missing declaration is a malformed plugin, not an old one — there is no legacy to default to.
