The supply-chain scan gates on non-baselined CRITICAL/HIGH findings. A newer
sentencepiece release reindented the stdout/stderr fd-redirect helper in
sentencepiece/__init__.py (the os.dup2 pair the heuristic flags as a
reverse/bind-shell pattern), moving it from L1221/L1226 to L772/L777 and
changing its leading indentation.
The baseline key is (package, package-relative file, check, evidence_hash),
where evidence_hash is over the matched code with the L<NN>: markers stripped
but the code's own indentation preserved. The reindent therefore changed the
hash (bba233.. -> 65b5a11c..), so the existing entry no longer suppressed the
finding and it resurfaced as a blocking CRITICAL in the hf-stack and studio
scan legs.
Add the new indentation variant to the allowlist. The calls are sentencepiece
redirecting stdout/stderr file descriptors to capture its C++ logs, not a
shell; no socket or networking is involved. The old L1221 entry is kept so
both versions stay covered.
