# HOME-to-HOME classified trip patch

## Definition

A complete trip is created from two consecutive NDI classifications with status `HOME`.

- Active trip start: `startHomeClassification.evidence.endedAt`
- Active trip end: `endHomeClassification.evidence.startedAt`
- Boundary evidence: both complete HOME classification objects
- Contained evidence: every `NOT_HOME` classification fully contained in the active trip window
- Country segmentation: calculated separately inside each completed trip

A middle HOME classification is shared: it closes the preceding trip and starts the following trip.

Classifications before the first HOME and after the last HOME are not assigned to a completed trip. Their count is exposed as `unassignedNonHomeClassificationCount`.

## Result additions

`DriverCountryTripSegmentationResult` now contains:

- `tripCount`
- `unassignedNonHomeClassificationCount`
- `trips`

Each `DriverClassifiedTrip` contains:

- `tripId`
- `startedAt`, `endedAt`, `durationSeconds`
- `startHomeClassification`
- `endHomeClassification`
- `containedNonHomeClassifications`
- `drivingIntervalCount`
- `countrySegmentCount`
- `countrySegments`

Each `DriverCountryTripSegment` now contains:

- `tripId`
- `countryCode`

The former flat `segments` collection remains available and is the concatenation of all per-trip segments. Compatibility constructors are retained for Java callers using the former record signatures.

## Pipeline order

`country-trip-segmentation` now explicitly depends on:

```text
support-evidence-normalization
ndi-home-classification
```

This guarantees that the trip boundaries are available before country segmentation starts.
