Decision-OS V5 Addendum — SiriusA Adoption Gate (0.3 Disclosure)

This addendum exposes a 0.3-disclosure adoption gate for Decision-OS V5 (SiriusA) so that the core life-protective operational design becomes readable and citable without revealing calibration-sensitive details.

**Disclosed (0.3)**
- Interface format and non-parameterized computation skeleton
- State machine: Request → Hold (Two-step) → Approve/Reject → Execute | Revoke
- Five-line output contract (incl. HOLD (evidence))
- Minimal evidence/audit bundle (non-PII; hash)

**Not disclosed (0.7)**
- Threshold values, calibration/update rules, Flip/BLOCK exception logic
- Data acquisition protocol (signals/denoising/filtering)
- Turnkey operational templates enabling copy-paste deployment

Priority: When irreversibility or coercion is plausible, the gate defaults to Hold-first control, prioritizing prevention of missed harm over minimizing false alarms.
