Question
Can irreversible resource loss push a still-running controlled system through structural, parametric and functional integrity regimes?
Research / EXP-01
Irreversible actuator damage
Executable baseline for a resource-dependent control model. The experiment asks what happens to integrity when control authority is irreversibly lost.

Model
A resource vector modifies the effective plant/control authority. Damage is applied as a one-way change; no repair process exists in EXP-01.
Fault
The declared actuator damage occurs at 5.00 s and produces an irreversible resource loss.
Observed transition
The run moves from nominal N to degraded K and then SK. Functional integrity decreases from 0.450898 immediately after the fault to 0.298923 at 5.03 s and reaches 0 at 14.52 s.
Meaning
The controller may continue issuing commands while the system crosses integrity boundaries. “Still running” is therefore not equivalent to “mission-valid”.
Limit
EXP-01 is a baseline, not proof that a supervisory reconfiguration strategy is better. Its plant mapping and disturbance profile are explicit synthetic assumptions.

Evidence & reproducibility
Raw data, code and audit artefacts remain directly inspectable for reproducibility and independent checking.
