IC Platform Runtime

The sole IC0, executor, CDK adapter and prepared-call implementation. This package and its macros/singleton guard have an independent Runtime release group. Crypto, certificates, Candid and native clients remain in ic-platform; identities remain in ic-platform-types. There are no default features.

Select ic0 for raw system calls, executor for method/task contexts, runtime for raw calls and prepared call::Call, or cdk for explicit-codec entrypoints. Use ic_platform_runtime::{ic0, executor, cdk, call}. Endpoint codecs and policy remain caller-owned. For a renamed dependency, pass the existing macro crate option with the selected runtime's CDK path.

Existing Platform facade paths delegate to this same owner. They install no second executor. Different runtime generations and the older embedded Platform executor remain mutually exclusive through the exact Cargo singleton guard. IC0/executor-only selections exclude Types, Candid, hashing and host adapters.

Imported Apache source/licenses and protected region fingerprints are retained. See the repository migration contract for source/archive qualification and the separate installed owner and Timers composition proofs. This package owns no scheduler, codecs, retries or storage allocation.
