The codex probe and the egress lib now carry one byte-identical block:
BASH_SOURCE under bash or %x under zsh, made absolute with $PWD, else a set
GSTACK_ROOT that holds the helper. Anything else (dash, sh, a shell that
cannot name the file) prints "gstack: cannot locate <helper> (shell: ...)"
with the docs/troubleshooting.md#sourced-helper-location URL and returns
before any bash- or zsh-only syntax. The Claude-only default path and the
$(pwd) fallback are gone.
The generated Codex preflight dot-sources the probe and, when it cannot load,
reports CODEX_MODE: helper_unavailable with the helper's own line instead of
falling through to not_authed. The class guard enumerates nested sources,
makes real resolver, auth, state-root and egress-home calls under bash and
zsh (absolute, relative then cd, bare name via PATH), covers dash and an
unknown shell, runs the full preflight, and lints BASH_SOURCE to the shared
block plus other bash-only constructs.
