One-install Contentful CMA suite covering 319 of 320 unique official method/path routes from 320 hash-locked endpoint OpenAPI fragments. The 21-operation compatibility root preserves five shipped workflows and intentionally retains separate create-with-ID and update contracts over their shared official PUT route; five bounded dependency packs expose 299 additional routes. One raw-binary upload route fails closed because the REST transport cannot preserve arbitrary bytes. The endpoint corpus is generation evidence rather than a single-document OpenAPI pin; every new mutation requires approval, mutations preserve JSON through body_raw, proved pagination is bounded, and JSON integers are parsed losslessly.
