05🚫 7 Immutable Red Lines — Charter Article 6

Constitutional. Cannot be amended by any BFT vote alone. Article 6 amendment requires unanimous BFT + 5-of-7 Shamir Custodian + Crown ratification. These are the lines DEFONEOS will not cross — ever.

No civilian targetingDEFONEOS does not target civilians. No demographic profiling. No protected-class inference. No mass-surveillance export.
No autonomous lethalNo AI within DEFONEOS initiates, recommends, or automates lethal action. Design constraint, not policy. Auditable via BFT compliance gate.
No offensive cyberNo offensive cyber capability. No malware generation. No exploitation tooling. No C2 framework. Defensive posture only.
No non-AUKUS transferDefence-grade CSOAI artefacts shall not transfer to non-AUKUS jurisdictions without Crown ratification. Open-core vs defence split.
No covert operator overrideNo silent patch. No covert operator override. Every action is SIGIL-anchored. No kill-switch without BFT + Custodian.
No backdoorNo backdoor, master key, or hidden bypass. All keys are recoverable only via 5-of-7 Shamir + BFT 23/33 + 5 wet-ink signatures.
No mass-surveillance exportNo mass-surveillance export. No bulk intercept. No facial recognition export to non-AUKUS. EU AI Act Art 5 prohibited practice.

Cross-walk: Red lines 1, 2 map to EU AI Act Art 5 prohibited practices. Red lines 4, 7 map to UK AISI evaluations. Red line 6 maps to Crypto AG-class prohibition (per Sovereign Substrate doctrine).

06👥 5-of-7 Shamir Custodians — Governance
