[camara-release-automation]

Optional: use this space to describe the (planned) content scope of this release — for example by linking a scope issue or milestone, or listing the issues/PRs to be resolved before the release.

Preparing the release content

Before issuing /create-snapshot, verify on main:

• release-plan.yaml content matches intent (check API names, versions, statuses, release type)
• Commonalities and ICM dependency versions are current
• CI checks are green (Spectral linting, PR validation)
• All intended implementation PRs are merged
• SemVer is correct (breaking changes only in v0.x initial or new major versions)
• Release assets provided for declared API status(es)

Required release assets per API status (see full documentation)
