entry-push-latest.yml gains a sync-main job that force-pushes the current repository's main from a source repo (default infinito-nexus/core) before CI policy and deploy discovery derive scope from origin/main. The source is configurable and can be disabled via CI_SYNC_MAIN_SOURCE_REPOSITORY; the same-repository case and disabled values skip the sync.
The sync-main checkout uses fetch-depth: 0 and the push is --force to avoid shallow-update and non-fast-forward rejections. Docs warn that main is force-overwritten and must not be used as a working branch on synced repositories.
