# bl-push-main — balls close.post plugin: deliver main to origin.
#
# bl close seals its squash-merge to main itself, outside `git commit`, so the
# repo's .githooks/post-commit hook never fires and upstream delivery stalls.
# Wired into close.post, this plugin restores it: once close lands the squash
# on main, push main to origin.
#
# Contract:
#   * answers the balls plugin protocol handshake;
#   * ignores stdin (drains a piped payload, never blocks);
#   * ALWAYS exits 0 — a non-zero exit in close.post triggers plugin rollback,
#     un-sealing a commit the remote may already hold; a push failure only
#     warns on stderr;
#   * acts on THIS project's repo, resolved from the plugin's own on-disk home
#     (<repo>/scripts/bl-push-main -> <repo>), so it is right regardless of the
#     dispatch working directory.

# Plugin protocol handshake: declare the ops we serve.
