name: Release Metadata Sync

# Keep generated version-carrying files in sync on release-please's branch.
#
# Why this exists
# ---------------
# release-please only rewrites `pyproject.toml` plus the `extra-files` listed in
# `.release-please-config.json` (currently the TypeScript SDK and OpenClaw
# package.json). Several other tracked files also carry the version, and
# `server.json` is asserted byte-for-byte against `render_server_json()` — which
# derives its version from `pyproject.toml`. So the moment release-please bumps
# the version, `tests/test_mcp_registry/test_server_json.py::
# test_root_server_json_matches_builder` fails on the release PR, and the release
# cannot be merged. That is what blocked v0.33.0 (PR #2339).
#
# `release.yml` already runs `scripts/version-sync.py` before its own
# `verify-versions.py` gate, so the release *build* self-heals in the workspace.
# The regular CI test job does not, so the fix has to be committed.
#
# Why a workflow rather than more `extra-files` entries
# ----------------------------------------------------
# `scripts/version-sync.py` is the single place that knows every version-carrying
# file. Restating that list as per-file jsonpaths would duplicate it, and a
# jsonpath that silently fails to match produces exactly the failure we are trying
# to remove. Running the script instead means files added to it in future are
# covered with no change here.
#
# Why the push trigger
# --------------------
# release-please regenerates (force-pushes) its branch on every merge to main.
# That is what repeatedly wiped the hand-pushed metadata fixes on #2339. Keying
# off a push to the branch means the sync re-applies after every regeneration
# instead of being lost.
