Application flow: Navigation built for intermittent connectivity

Reliable guidance across coverage gaps without giving up traffic, search freshness, or safety.

The real-world moment

A vehicle crosses a long connectivity gap after receiving a regional data update the night before. Navigation must boot with a compatible signed offline package, plan and guide locally, blend online traffic/search when available, protect driver attention, and recover automatically if the new package or runtime is unhealthy.

Operating contract

Make ownership visible before code.

Compose multiple capabilities while the application owns user intent, policy, and continuity.

Vehicle/OEM identity

Activate the head unit

Owns hardware, market/region, entitlement, runtime compatibility, privacy/consent, activation and update campaign.

Supporting operation

Vehicle manifest ↔ hardware/runtime/region/entitlement versions

GETGets the live data of devices./deviceThis is a supporting operation from the selected product stack, not proof of an exact provider contract for this stage. Resolve the stage through its product source or adapter boundary before live implementation.

Evidence to retain

Record stage 1 with the application identity, source fingerprint, request or aggregate identity, timestamp, and observable outcome.

Failure drillPower loss during update

Write only the inactive slot and switch one atomic pointer after verification; boot always finds a previously acknowledged package.

Dual-slot offline runtime

Install compatible signed regional data

Maintains one active and one staged signed package, atomic activation pointer, health acknowledgement and rollback evidence.

Supporting operation

Data package ↔ epoch, region, size, content/signature hash, compatibility

GETGeocode API/api/places/geocodeThis is a supporting operation from the selected product stack, not proof of an exact provider contract for this stage. Resolve the stage through its product source or adapter boundary before live implementation.

Evidence to retain

Record stage 2 with the application identity, source fingerprint, request or aggregate identity, timestamp, and observable outcome.

Failure drillOnline traffic disappears mid-route

Keep guiding from the last valid local route, mark traffic freshness and avoid blocking safety-critical guidance.

Local navigation

Plan and guide offline

Search index, routing graph, guidance and map rendering operate without network under pinned runtime/data/profile versions.

Supporting operation

Route session ↔ offline/online sources, profile, data/traffic versions

GETRouting API/{REST_KEY}/{resources}/{profile}/{geopositions}This is a supporting operation from the selected product stack, not proof of an exact provider contract for this stage. Resolve the stage through its product source or adapter boundary before live implementation.

Evidence to retain

Record stage 3 with the application identity, source fingerprint, request or aggregate identity, timestamp, and observable outcome.

Failure drillNew package boots but fails route smoke test

Fail health acknowledgement, restore the prior slot and upload privacy-safe diagnostics when connectivity returns.

Online enhancement

Blend online traffic and search when available

Trusted cloud boundary adds fresh search, traffic and telemetry only when entitled and available; responses carry freshness/provenance.

Supporting operation

Update event ↔ campaign, stage, evidence, event/receipt time, health/rollback outcome

GETGets the historical location events of a device./devices/{deviceId}/eventsThis is a supporting operation from the selected product stack, not proof of an exact provider contract for this stage. Resolve the stage through its product source or adapter boundary before live implementation.

Evidence to retain

Record stage 4 with the application identity, source fingerprint, request or aggregate identity, timestamp, and observable outcome.

Failure drillPower loss during update

Write only the inactive slot and switch one atomic pointer after verification; boot always finds a previously acknowledged package.

Interactive contract lab

Edit once. Generate eight trusted-runtime implementations.

The recipe starts from the normalized GET /{REST_KEY}/{resources}/{profile}/{geopositions} contract. Execute six deterministic fixture outcomes before an issued account is involved.

Reliability contract

These controls are required at this operating depth; deeper recipes add durable truth rather than merely more API calls.

Application-owned intentStable cross-capability identityPartial-failure fallbackCancellation and teardownFreshness and provenanceQuota and latency budget

Definition of done

Every capability has one owner, bounded input, explicit timeout, and useful unavailable state.

Application intent survives refresh, back navigation, duplicate callbacks, and partial capability failure.

Provider identities, source fingerprints, request identities, and application decisions remain attributable.

Accessibility, privacy, quota, observability, support, and rollback evidence cover the complete user flow.
