Testing-specialist findings, all mechanical: (1) pin the E2E fixture's git
branch (-b main / init.defaultBranch=main) and assert every setup command's
exit status so operator git config can't silently corrupt a paid run;
(2) tighten the dispatch matcher to Step 18-prompt-specific markers
(document-release/SKILL.md | executing the /document-release workflow) so a
subagent merely quoting section text can't false-pass the regression assert
(verified against recorded burn-in transcripts); (3) replace the subsumed
carve-guards anchor with three non-overlapping per-touchpoint anchors
(gerund/imperative/3rd-person) so each touchpoint is independently enforced.

New skill-e2e-ship-docsync: a live agent gets the sliced Step 17→19 tail
of the generated ship skeleton in a bare-remote git fixture (Steps 0-16
"done"), under a fake HOME so the STOP pointer and the Step 18 subagent
prompt resolve to planted copies, with a stub document-release skill that
returns the empty-result JSON contract. Hard assert: an Agent/Task
tool-call matching /document-release/i exists in result.toolCalls and
precedes any `gh pr create`. Neutral prompt (no STOP-Read priming, no
document-release mention — the prompt echoes into the transcript, so
asserts read toolCalls only).
Hardening from review: throw-on-marker-drift fixture slice; per-test
GSTACK_HOME + .redact-prepush-prompted marker (routes Step 17's
credential guard to its silent branch — the hermetic GSTACK_HOME pin
defeats a HOME-only override); 480s/540s timeouts (nested subagent adds
wall clock the 300s sibling never carried); 'timeout' accepted in
exitReason only because the dispatch assert is independently hard;
whole-file describeE2ETier('gate') composed with diff selection (keeps
the file out of the periodic shard census, which sits at its ceiling,
and under the hard tier-alignment invariant).
Registered as 'ship-docsync' in E2E_TOUCHFILES + E2E_TIERS (gate) in the
same commit — touchfiles.test.ts rejects either half landing first.
