ci/woodpecker/pr/ci Pipeline failed
Pipeline 2635 (merge-verify of 8eb7e635) failed one advice assertion
('a PR is an issue where labels live...') while pipeline 2634 (same
content, PR event) and 2636 (same tree + one commit) both passed, and the
fixture is stable under 200 direct iterations, 10 suite runs, four
locales, and 60 suite runs inside alpine/busybox 1.37 (the CI userspace).
Mechanism: the harness's 'if ! ... | grep -Fq' shape treats ANY nonzero
from the pipeline as an advice mismatch — including a transient grep
failure (fork/alloc error on a loaded k8s node), which prints the
identical FAIL line without any guard defect. The guard's rc-2 sites were
audited: every classification branch that can fire on this payload names
issue-edit.sh, so no code path produces the observed output.
Fix: the advice assertion now retries grep on rc>=2 (tool error) up to
3x, treats rc=1 as the real mismatch, and on persistent tool failure
prints a distinct TOOL-ERROR line (still fail=1 — never green on
infra noise, but the line names the class so a re-run can be judged
instead of debugged as guard drift). Advice-mismatch direction proven
unchanged by mutation (bogus wrapper name still FAILs both labels arms).
Suite 292/292 x2 locally and under busybox.
