KNOWLEDGE CARD / README

Portable policy knowledge for local retrieval.

A schema change is a deployment-order problem across producers, consumers, storage, and time.

Additive evolution is usually safer than changing meaning in place.

Test the wire contract and the oldest consumer that can still be active.

Intended use

Grounding API and event designers while changing schemas shared across services, clients, or stored data.

Out of scope

This pack does not define a serialization vendor, approve a breaking change, or replace a versioned product contract.
