Struct HarnessMcpOpaquePayloadV1 

pub struct HarnessMcpOpaquePayloadV1 {
    pub content_type: HarnessMcpContentTypeV1,
    pub body: Vec<u8>,
}

An opaque harness-MCP payload.

This is the carriage this crate’s wire types actually move end to end (HarnessMcpLocalRequestV1::request, HarnessMcpLocalReplyV1::Ok:: response, NodeEvent::HarnessMcpReadCall::request): body is whatever bytes the originating endpoint encoded, and this crate never decodes it. Only the reviewed local helper (hatchery-harness-mcp bin from hatchery-harness-mcp, which holds hatchery-harness-api types via hatchery-harness-client) and hatchery-harness-service (the harness itself) know what body actually contains.

This is the Nested Control Plane doctrine’s Law 3 made mechanical (docs/architecture/nested-control-plane.md): a lower tier (node, wrapped by c2) must never import a higher tier’s (the harness’s) crate. Before this type existed, HarnessMcpLocalRequestV1/HarnessMcpLocalReplyV1 carried the harness’s own HarnessReadRequestV1/HarnessReadResponseV1 typed, which pulled hatchery-harness-api into this crate’s dependency graph and, through it, into every crate that re-exports this one – node, node-wire, c2, c2-client. A relay that cannot read what it relays is a relay done right.
