Examples
Upgrade an SDK through a compatibility canary
Pin the candidate SDK version in a branch and run the development agent suite against synthetic create-call, retrieval, error, and webhook scenarios. Record the old and new package versions and any changed request shapes, then deploy a preview configuration before altering production dependencies. Keep the prior lockfile and agent version available until the canary has met its error and latency limits, so rollback does not require reconstructing the old runtime.
