This branch is rebuilt from main on every spec change and force-pushed, so it always reflects the latest generated output. Hand-written files in this repository are left untouched; anything under the generated surface is replaced on the next update, so fix the specification rather than editing here.

This PR is squash-merged automatically by the api-spec merge job, which then lets release-please open this SDK's release PR. Every type in release-please-config.json except test and ci is a non-hidden changelog section, so docs and chore cut a patch just as feat/fix do.
