The recurrence guard, and #2665's own "Optional hardening". This class is silent by construction: TEST_ENV_BASE cannot see an in-process caller, and CI cannot see the class at all because CI never has these env vars set. It damages the developer's machine and reports nothing -- which is how two prior authors each diagnosed it and fixed only the instance in front of them. run-tests.cjs snapshots GSD's install footprint in every live runtime config dir before the suite and re-checks it after, failing the run on a create or a modify. Roots come from the product's own getGlobalConfigDir, so the guard watches wherever the product actually points, including through an ambient var. Scope is ownership-based, not whole-root: the top-level install footprint plus gsd-prefixed children of dirs GSD shares with the host agent. A config root like ~/.claude is shared, and watching it wholesale would false-positive on the host's own history.jsonl or settings.json -- a guard that cries wolf gets disabled, and then catches nothing. The prefix test is load-bearing: the first version watched only the three top-level entries and MISSED a real leak into skills/gsd-*. It earned its place immediately -- it is what found the fifth in-process leak in runtime-artifact-layout.test.cjs, which no amount of reading the review would have surfaced. Known gap documented in the module: a write to a file GSD does not own is out of scope by construction. Lives in scripts/, deliberately NOT scripts/lib/ -- the installer copies that dir into every user's config dir wholesale while uninstall removes only an allowlist, so a test-only module there would ship to users and survive uninstall. Addresses review finding: Minor 8.
