Node test suites run inside an OpenRig seat no longer inherit that seat's instance. The daemon and TUI suites now use the same fixture-home and fetch-guard setup as the CLI suite (test/hermetic-env.setup.ts). OPENRIG_* and RIGGED_* instance selectors are cleared before product imports, so tests cannot reach the person's OpenRig home, database or daemon endpoint.
Ordinary runs also redirect HOME and the XDG directories and clear CODEX_HOME. With OPENRIG_E2E_REAL_CODEX=1, the real HOME, CODEX_HOME and XDG directories are kept, so the opt-in real-Codex tests run as before. Explicit fixture overrides set after setup still apply.
Test-only; no product code changes. Controls against disposable outer audit, SQLite and HTTP targets fail with the old setup and pass with the new one. Not covered: subprocess globals and hardcoded filesystem targets outside the fetch guard.
