Evidence for mission resilience.
Current results are simulation-backed and demonstrate the intended behaviour of HOLDFAST and VERITY under controlled degraded-communications scenarios.
More critical traffic delivered under degradation.
Across the complete 580-run abstract-bearer dataset, HOLDFAST Core and Adapt configurations produced higher mean C2 delivery than the AODV-labelled abstract baseline proxy. VERITY adds trust-assessment evidence without changing packet delivery — by design.
Finding
Communications continuity
In controlled simulations, HOLDFAST configurations delivered more critical traffic than the modelled baseline across the complete abstract-bearer dataset.
Finding
Custody through disruption
The model exercises custody and store-forward behaviour intended to preserve critical messages across temporary loss of connectivity.
Finding
Bounded adaptation
Adaptation depends on reliable evidence and must remain bounded when network conditions change faster than confidence can accumulate.
Finding
Trust-assessment evidence
VERITY produced additional confidence, uncertainty and review evidence without claiming packet-delivery improvement.
Simulation-backed today. The next gate is the Resolvix Node Runtime and platform-adapter architecture; live RF/GNSS, hardware-in-the-loop and controlled field validation follow in later phases.
Two separate evidence families with different model boundaries.
These are preserved legacy simulation evidence from the pre-Node-Runtime architecture, retained as the platform is re-packaged around the Node Runtime and versioned adapters. Evidence is drawn from two separate simulation workstreams. Evidence Family A is an abstract-bearer simulation (580 paired runs per comparison) that models custody, continuity, uncertainty and trust-assessment proxy metrics. Evidence Family B is an ns-3 stack comparison using a custody-favourable scenario.
The two families are not combined. Family A attributes a modelled adaptation gain to HOLDFAST Adapt. Family B shows Adapt as assessment-only and behaviour-neutral, with delivery gain attributed to HOLDFAST Core.
HOLDFAST improves C2 delivery in the abstract simulation.
HOLDFAST Core lifts mean C2 delivery from the abstract baseline through custody, priority and store-forward behaviour. In this simulation, HOLDFAST Adapt adds a modelled adaptation gain. VERITY adds trust-assessment evidence without changing delivery.

Key message
HOLDFAST improved C2 delivery. VERITY contributed trust-assessment evidence — operating exactly as designed, above the delivery layer.
Core delivers the gain. Adapt is assessment-only in this comparison.
In the pinned ns-3 custody-favourable scenario, HOLDFAST Adapt operates as assessment-only and behaviour-neutral. The observed delivery difference between the ns-3 AODV baseline and HOLDFAST modes is attributed to HOLDFAST Core custody and store-forward behaviour alone.

What the simulation demonstrates. What later validation adds.
What this demonstrates in simulation
- The pinned abstract simulation produced deterministic, reproducible outputs for its configured model.
- Across the complete 580-run abstract-bearer dataset, HOLDFAST Core and Adapt configurations produced higher mean C2 delivery than the AODV-labelled abstract baseline proxy.
- In the ns-3 comparison, HOLDFAST Core custody and store-forward behaviour accounts for the observed delivery difference; Adapt is behaviour-neutral.
- VERITY produced deterministic trust-assessment proxy metrics and review signals without changing delivery.
What later validation establishes
- Live RF, GNSS, SDR and waveform validation — later hardware phases.
- Operational and field validation — the controlled field-pilot phase.
- Representative adversary emitter and threat behaviour — live RF testing.
- Performance under representative constrained-node hardware — later hardware phases.
- Multi-seed ns-3 aggregation with confidence intervals — planned for a later phase.
Next: the Node Runtime. Live RF / GNSS / HIL follows.
