AquaShield staged test plan

Gate	Test article	Pass evidence	Stop condition
AQ-0	Equations and calculator	Independent unit review and reproduced outputs	Unit or conservation error
AQ-1	Bench loop, no chamber	Stable flow, gas separation, filtration, heat balance	Cavitation, uncontrolled gas, leak
AQ-2	0.50 m³ uncrewed flexible cell	Force mapping, drain, isolation, mass closure	Entrapment geometry or failed isolation
AQ-3	Fault-injection rig	Single-fault containment and manual egress fixture	Inventory loss or software-dependent escape
AQ-4	Radiation transport model	Mission-specific dose comparison with uncertainty	No useful benefit at credible mass
AQ-5	Reduced-gravity uncrewed article	Controlled liquid/gas interface and drainage	Persistent gas pocket or loss of control
AQ-6	Human-factors ground protocol	Independent medical/IRB approval first	Approval absent or unacceptable hazard
AQ-7	Flight technology demo	Agency safety approval and telemetry	Any unresolved catastrophic hazard

AQ-2 falsification matrix

The concept fails its initial buildability gate if any of the following survives redesign:

• total water cannot be isolated after one valve or membrane failure;
• a passive/manual occupant release cannot be demonstrated;
• force output cannot be controlled and independently measured;
• gas cannot be separated fast enough to protect pump and breathing boundaries;
• thermal rejection exceeds the available system budget;
• water transfer produces unacceptable center-of-mass excursions;
• sanitation cannot meet the selected human-contact standard.

Null results and stopped tests are reportable outcomes.
