Model, provenance, and limits
This is a deterministic interface test bench, not a sensor feed. For an isotropic 2D Gaussian, the assumed radial coverage is r95 = √(−2 ln 0.05) × σ. The toy scenario uses σ = base uncertainty + age × an illustrative source coefficient. Coefficients are authored test controls, not measured GNSS, visual, or inertial performance. A ±20 m corridor is illustrative. A positional confidence envelope is not an integrity protection level. No safety authority or hardware actuation is granted.
Research record
From question
to evidence.
- 01 / Question
- Can a source handoff be understood together with its consequences for assurance?
- 02 / Hypothesis
- Showing the fallback plan alongside Accuracy, Integrity, Confidence, and Latency may improve interpretation of a source transition.
- 03 / Method & prototype
- Compare source-only labels against a PACE waterfall with AICL. Include nominal, degraded, unavailable, and recovery scenarios. Keep integrity distinct from positional confidence. The shared synthetic test bench is an interaction prototype; completing the proposed study requires task design, participant recruitment where relevant, and recorded evaluation.
- 04 / Observation
- Evaluation pending. No participant-study results or field-performance findings are reported in this initial protocol.
- 05 / Measures
- Correct source identification, detection of inadequate or unknown integrity, response time, and over-trust.
- 06 / Systems implication
- Candidate: explain the effect of a source transition, rather than treating a source name as proof of adequacy. Promotion depends on evidence of improvement against the baseline, with failure cases and limitations recorded.
