Design and version a Cogitave API
Shape a clean, consistent API against the Cogitave API design standard - resources, standard methods, typed errors, cursor pagination, idempotency - then version and deprecate it under the versioning policy so no consumer is ever broken without consent.

By the end of this module, you'll be able to:
- Design a resource-oriented, contract-first API that meets the same shape across HTTP, gRPC, GraphQL, and MCP, using the conventions the API design standard fixes.
- Apply the estate-wide MUST invariants - the RFC 9457 error model, the
codetaxonomy, cursor pagination bounds, and idempotency on creating writes - and know when a default needs a recorded deviation. - Pick the right versioning scheme per surface and evolve a contract additively without breaking a live consumer.
- Walk a contract through the deprecation lifecycle - deprecated, sunset, retired - keeping the API, docs, and changelog in lockstep from one deprecation manifest.
