// Workflow .md text IS what the runtime loads and the agent executes, so
// asserting on its shell invocations tests the deployed contract directly.
//
// Repo-wide regression guard for #637 (generalizes the plan-phase-only guard
// from #621): NO workflow .md may invoke gsd-tools via a hardcoded
// `node "$HOME/.../gsd-tools.cjs"` path. On a global/shim-only install with no
// project-local runtime, that path can miss a working install, so the step
// reports the tool "not found" instead of resolving it. Every invocation must
// go through the `gsd_run` launcher (defined once per file in the canonical
// preamble, which resolves RUNTIME_DIR → .claude → PATH → $HOME in order).
//
// The parity test (runtime-launcher-parity) guards the retired $GSD_SDK and
// bare /gsd-tools tokens but NOT this hardcoded-node form — which is exactly
// how it survived across plan-phase.md (#621) and three more files (#637).
