- * (a common policy), --exclude-standard filters out the very files the rescue
- * was meant to save, producing an empty result and skipping the rescue branch.

+ * handles SUMMARY rescue internally using a filesystem-level find+cp approach

+/**
+ * Regression test for #3668: --local install has soft dependency on global gsd-sdk
+ *
+ * Two defects confirmed by code inspection:
+ *
+ * Defect 1 — `buildGsdSdkVersionMismatchReport` emits `npm install -g get-shit-done-cc@latest`
+ *   unconditionally, even when the caller is a local install. For local installs the
+ *   correct remediation is to run `/gsd:update` (or `npx get-shit-done-cc@latest --local`),
+ *   not to install globally.
+ *
+ * Defect 2 — 69 of 72 workflow files that call `gsd-sdk query …` do so without a
+ *   `[ -f "$GSD_TOOLS" ] … elif command -v gsd-sdk` fallback, so uninstalling the
+ *   global `gsd-sdk` breaks every workflow on a fresh local session.
+ *
+ * Defect 3 — No CI guard prevents future workflow regressions.
+ *
+ * Acceptance criteria (from confirmed-bug triage comment):
+ *   - `renderGsdSdkVersionMismatchReport` does NOT emit `npm install -g` for isLocal=true.
+ *   - All SDK-invoking workflow files (recursively) use the local-first guard pattern.
+ *   - A CI guard (Defect 3) blocks any future workflow file from invoking bare `gsd-sdk`
+ *     without a resolution guard. The guard also catches untyped fences, not just bash/sh.
