* fix(#4341): reference-count the git-config sandbox the three guard suites share node:test evaluates every describe body during collection, before any test runs, so the three isolateGlobalGitConfig() calls happened back to back and each captured the PREVIOUS call's temp path as its "original": A captured undefined, B captured A's path, D captured B's. Suite A's after() fires first and restored undefined — deleting GIT_CONFIG_GLOBAL outright — so suites B and D ran against the developer's real ~/.gitconfig for the rest of the file. A also cleanup()'d a directory B still pointed at. One sandbox now, with the true original captured once and released when the last holder lets go; each returned restorer is idempotent, so an extra call cannot release someone else's hold. The three call sites are unchanged. Reproduced with a global core.hooksPath (via a fixture HOME carrying a .gitconfig, so the developer's real one is never touched): next: ℹ pass 291 ℹ fail 7 — "core.hooksPath is set to ...; a hook written to .../pre-commit would never run" branch: ℹ pass 296 ℹ fail 3 The 3 that remain are two suites (pr-subrepo, #3776 query commit --files) that never called isolateGlobalGitConfig at all — the same class, a different gap, and outside this issue's scope. Noted on the PR. D0 is the regression guard and is deterministic on every lane: suite A's after() runs before this suite's tests, so on the old helper GIT_CONFIG_GLOBAL is already gone by then regardless of what the host's git config contains — which is what makes it fail on CI, where the core.hooksPath that exposed the defect is absent. Verified: full-file run reds on the old helper, greens on the new one. * test(#4341): clean filtered gitconfig sandboxes on exit * test(#4341): retain exit cleanup until release succeeds
