# NO `paths:` filter on purpose (issue #447). The tool-spec REGISTRY is split
# across two packages that MUST stay in sync: the specs live in `packages/mcp`
# but the parity/tier guard tests that read them live in the `apps/server` jest
# suite. A PR touching only `packages/mcp/**` must therefore still run the SERVER
# suite (and vice-versa), or an in-app wiring break slips through green and only
# surfaces on develop after merge. The `test` job below runs BOTH suites via
# `pnpm -r test` on every PR; the dedicated `mcp-server-parity` job makes that
# cross-package gate explicit and fast. Do not add a `paths:` filter here.

  # Guard against a long-lived branch adding a migration whose timestamped
  # filename sorts BEFORE migrations already applied on the target branch (and
  # thus in prod). The Kysely startup migrator rejects that as "corrupted
  # migrations" and crash-loops the app on boot (incident #361). This gate fails
  # the PR so the migration is renamed to a current timestamp before merge. Only
  # runs for pull_request events (needs a base branch to diff against).
