IC Wire Endpoint

Typed query and update entrypoints backed by independent IC Platform Runtime. Core codec, Limits/Error and schema identities remain owned by ic-wire independently of runtime integration releases. Platform owns execution and the singleton guard.

Replace Wire's removed endpoint feature with an ic-wire-endpoint dependency. Move attributes/helpers from ic_wire::endpoint to ic_wire_endpoint; retain codec and schema imports from ic_wire. Enable typescript here for native Contract schema projection. Frame bytes, bounds, acceptance and rollback rules are unchanged. See the repository endpoint guide for handler examples.

Independent Runtime adoption

Endpoint 0.4 selects published ic-platform-runtime = "0.17.1" directly, with Core 0.14 schemas on canonical Types 0.16. Applications that use low-level APIs select that package's cdk feature and use ic_platform_runtime::{cdk, executor, ic0}. Handler macros continue to target the runtime re-exported through Endpoint; applications need no new dependency solely to use an Endpoint macro. Core and derive keep their independent release identity.

Select matching Timers and other runtime suppliers before upgrading applications. Runtime/macros/exact guard 0.17.1 are published. Legacy embedded Platform 0.16 executors cannot coexist with Runtime 0.17. Crypto/Candid facade features may be selected separately with a facade that delegates to this owner. Qualification uses the normal registry lock without supplier patches. The private native fixture retains its older qualified facade/Testkit client; no facade enters the production Endpoint graph.
