Two hermeticity holes surfaced by the wave's final gate. (1) The three T6
tripwires (branch-slug, codex-flag, empty-find) enumerated the whole tree
including the workspace-local .claude/ install, which is not generated
output and can carry dangling symlinks from unrelated sessions — one ENOENT
there failed all three. They now scan repo sources only. (2)
browse/test/cdp-e2e.test.ts mutated process.env.GSTACK_HOME at module scope
without restore; in one-process shard runs that leaks into every later test
file — observed baking cdp-e2e's temp render path into artifacts that
outlived it (53 dangling SKILL.md symlinks in a workspace install). The
original value is now restored in afterAll. The exact test that performed
the polluted relink remains unattributed; both known leak vectors are
closed and the workspace was repaired via an explicit gstack-relink.

find ... | xargs ls -t runs ls with NO operands when find matches nothing —
GNU xargs still invokes the command once, and ls -t with no operands lists
the current directory. Three sites misfired on fresh installs (no ceo-plans /
checkpoints / plans yet), exactly where a wrong answer is least likely to be
recognized: review.ts's plan fallback silently adopted a random cwd .md as
"the plan", and Context Recovery listed unrelated cwd files as RECENT
ARTIFACTS / LATEST_CHECKPOINT.
All three now use xargs -r ls -t, mirroring the shape the sibling
bin/gstack-codex-session-import fix (#2482) landed with: -r pins the BSD
skip-on-empty behavior on GNU too, and BSD xargs accepts -r as a no-op.
test/empty-find-fallthrough.test.ts pins it four ways: no bare xargs ls -t
in scripts/ or bin/, both rendered Context Recovery sites guarded, a live
execution proving an empty checkpoints dir yields no checkpoint (not a decoy
cwd file), and a rendered-SKILL.md sweep.
