Position confidence is a state.
Raw, fused and matched evidence retain uncertainty, source, calibration and candidate context. Ambiguous grade separation and expired dead reckoning hold guidance explicitly.

One route truth—from position evidence to every cockpit surface.
Build installed and enriched routes, qualify vehicle position, enforce moving-state interaction policy, progress revisioned guidance and keep IVI and cluster consumers aligned. Then exercise flyover ambiguity, tunnel dead reckoning, stale traffic, offline operation and incompatible content.

Route truth is revisioned once.
Trip identity, route revision and ordered guidance sequence remain coherent across the primary IVI and read-only secondary displays—even when one subscriber disconnects.
Offline is a designed baseline.
Installed search, routing and guidance remain useful without cloud enrichment. Stale traffic stays visible as evidence but cannot silently influence the effective ETA.
Application to silicon boundary
Evaluate the cockpit, three embedded runtimes and navitainment hardware as one system.
Each product is independently scopeable. Their content compatibility, signal authority, positioning confidence, route state, lifecycle and display projection must remain coherent.
