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.

Branch-name-to-filename had incompatible rules across writer and readers:
gstack-review-log WRITES <branch>-reviews.jsonl with the gstack-slug
canonical form (tr '/' '-' then tr -cd 'a-zA-Z0-9._-', bin/gstack-slug:178),
but Context Recovery PROBED it with raw $_BRANCH from git branch
--show-current — so for any branch containing a '/' the REVIEWS line never
fired (#1851's reader half of #1127). The probe now uses ${BRANCH:-unknown},
the canonical value the gstack-slug eval on the block's first line already
sets. review.ts's plan content-search BRANCH gains the missing tr -cd half
so it matches the same canonical pipeline.
Full audit of the 5 raw $_BRANCH interpolation sites in scripts/resolvers/
(E3): generate-context-recovery.ts:16 (reviews.jsonl path) -> canonical
BRANCH; :19/:21 (timeline.jsonl content greps) KEEP raw $_BRANCH because the
timeline writer (preamble's gstack-timeline-log call) stores the raw branch
in the "branch" field — slugging the reader would break that pairing;
generate-preamble-bash.ts:29 (display echo) and :97 (timeline data write)
keep raw by design. The *-$BRANCH-design-*.md family (review.ts:313 + 3
plan-review templates) is a consistent tr '/' '-' writer/reader pair and is
deliberately untouched.
test/branch-slug-hygiene.test.ts pins the discipline: a rendered-output
sweep forbids raw $_BRANCH adjacent to a path separator or as a filename
prefix in ANY generated SKILL.md/section, and a live round-trip on a
feat/slash branch proves gstack-review-log's write is found by the rendered
probe (with the raw-form shape as a negative control).
