RM-02's registered fixtures found this before the registry was built. Worse than the
banked unknown=>exit 0: ci-queue-wait.sh:266 pipes the payload into a classifier
starting 'python3 - <<PY', so python reads its PROGRAM from stdin and json.load never
sees the JSON. Proven empirically — success, failure, pending and malformed all
classify as unknown, and unknown exits 0.
The mandatory pre-push/pre-merge guard therefore returns PASS for every possible input,
including a genuinely failing CI. The six observed meaningless greens were not an edge
case; they are the only output it can produce.
PR #1023 is exactly this fix, open and parked, and its body diagnoses it precisely.
Two aggravating details from that body: pr-ci-wait.sh:38 documented the bug and remedy
and it was never backported to the mandatory sibling (D-14 propagation with a
security-adjacent blast radius); and the fix was opened without re-verification.
Escalated for Jason's #1023 disposition. RM-02 records required-vs-actual with
DEFECT (owner: RM-03); no RM-03 lane opened, guard not edited.
