- Add # nosec B104 to all intentional 0.0.0.0 binds in honeypot servers (hardcoded_bind_all_interfaces is by design — deckies must accept attacker connections) - Add # nosec B101 to assert statements used for protocol validation in ldap/snmp - Add # nosec B105 to fake SASL placeholder in ldap - Add # nosec B108 to /tmp usage in smb template - Exclude root-owned auto-generated decnet_logging.py copies from bandit scan via pyproject.toml [tool.bandit] config (synced by _sync_logging_helper at deploy)
