T-20: identify interfaces by exact scope/name pairs; add optional opaque scope_ref metadata and separate shape validation from path-dependent scope compatibility. Preserve call error precedence, strict JSON, validators and transport boundaries. Mechanically migrate consumers and document API/wire compatibility and deferred lifecycle semantics. Validation: cargo fmt --all --check; git diff --check; cargo check --workspace --all-targets; cargo test -p wip-protocol -p wip-http; cargo test --workspace (221 passing tests including doctests); cargo test --workspace --all-targets; nix develop --command cargo clippy --workspace --all-targets -- -D warnings; RUSTDOCFLAGS="-D warnings" cargo doc --workspace --no-deps. All pass. cargo/rustc 1.95.0; development-shell Clippy/rustc 1.97.1.
wip-http
Framework-independent WIP over HTTP v1 endpoint, route, JSON codec, and response-classification support.
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 = "0.1.0"
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.
