Enum OriginClass 

pub enum OriginClass {
    FirstParty,
    ThirdParty,
}

Trust origin of a schema (or the mem that pins it), decided at adopt/write time and reported — never re-derived — on the read path.

FirstParty is an engine built-in or a schema authored/explicitly trusted in this workspace. Its prose-instruction fields (system_context, write_rules, writing_guidance, when_to_use, prose description, default_writing_guidance) guide authoring in this workspace and are served in full.

ThirdParty is a schema that arrived from outside this workspace (registry-installed or adopted from a foreign folder/clone) and has not been explicitly trusted. Memstead’s value proposition pulls a mem’s schema directly into a consuming agent’s context, where the schema’s free-text fields are framed as instructions (“System context”, “Writing guidance”). A third-party schema is therefore served structural-only: build_schema_payload forces the SchemaVerbosity::Lite skeleton regardless of the requested verbosity, omitting every prose-instruction field. This is lossless for the legitimate use case — the omitted fields only guide writing, and a write never targets a foreign mem.

The class is unforgeable by a publisher: it is decided by how the schema entered the workspace, not by any content the schema carries. An unknown/ambiguous origin classifies ThirdParty — the safe default (a stranger’s prose is never served as first-party instructions on the strength of a missing label).

Variants

FirstParty

Engine built-in, or authored/explicitly trusted in this workspace.

ThirdParty

Arrived from outside this workspace and not explicitly trusted. The safe default for an unlabelled/ambiguous origin.

Implementations

impl OriginClass

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

The wire token for this origin ("first-party" / "third-party"), emitted on every schema read so a consuming host can quarantine non-first-party content.

pub fn is_third_party(self) -> bool

Whether this origin must have its schema served structural-only (prose-instruction fields omitted) on the read path.
