The crate maps the three WIP Core interactions to fixed HTTP routes and strict UTF-8 JSON representations. It constructs and validates http request and response values but deliberately performs no network I/O and does not define TLS, authentication, proxy, or connection policy.

[dependencies]
wip-http = "0.2.0"

use wip_http::wip_protocol::ObserveRequest;
use wip_http::{Endpoint, Limits, encode_observe_request};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let endpoint = Endpoint::parse("https://example.test/wip")?;
    let limits = Limits::new(64 * 1024, 1024 * 1024, 64)?;
    let request = encode_observe_request(
        &endpoint,
        &ObserveRequest { path: "/".into(), depth: 0 },
        limits,
    )?;
    assert_eq!(request.uri(), "https://example.test/wip/v1/observe");
    Ok(())
}

Interface references and scope identity

Every interface reference is encoded as an exact JSON object with required scope and name strings, for example {"scope":"/github","name":"issue.read"}. This applies to Object.interfaces elements, fetch request/response interface, and call interface.reference. Scope must be a canonical absolute Worldspace path and name must be nonempty. Legacy opaque strings, short-form strings, relative scopes, missing fields, and extra members are rejected. Unicode, ::, and # in names remain literal data; comparison uses decoded field values, independent of JSON member order and escapes. HTTP endpoint prefixes do not change Worldspace scope.

Fetch responses and call interface targets additionally carry optional scope_ref, an opaque string copied from the scope Object's ref observation. It is not base64 and is not part of interface identity. Absent values are omitted; null and nonstring values are rejected. Descriptor-independent call metadata validates reference shape, but leaves scope ancestry and identity preconditions to the Host's InterfaceMismatch check, preserving protocol error precedence. Invalid success responses remain client-local InvalidResponse errors; protocol error envelopes and transport failures retain their existing classification.
