Reviewer's GuideThe PR fixes a mismatch between sleep continuation detection and final main-sleep selection by reusing the detector’s inclusive 90-minute continuation limit when bridging sessions. Synthetic regression tests cover retained 70-minute interruptions, separation beyond the limit, and preservation of wake versus unobserved gap classification.

**Fragmented nights bypass the span cap**
When multiple accepted sessions, each under the 16-hour run cap, form a chain whose combined span exceeds 16 hours, a chain of individually qualifying sessions with gaps up to 90 minutes is merged without checking the combined span, so `segmentSleep` can select and report an in-bed interval longer than the 16-hour cap.
Enforce the 16-hour limit on the combined group span before merging or selecting it.

The comment says "an hour awake". The test uses a 70-minute gap, which is the case that exceeds the old 60-minute limit. Update the comment to name the 70-minute gap and the 90-minute continuation limit.

Review comments at @test/onehz/sleep_continuation_test.dart:
- Around line 9-13: Update the sleep-continuation scenarios and their fixtures
to include a detected-session boundary where session.start minus the prior run’s
last end timestamp is exactly 90 * 60 seconds; account for _buildRuns using the
last sample timestamp as end. Assert or configure the detected boundaries so the
test fails if the 90-minute comparison changes from <= to <.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.Fixture uses a hard-coded 342-second offset.
The
gap - 342constant depends on the still-window filter and run-endpoint behavior inAdvancedSleepStager. The test assertssessions[1].start - sessions[0].end == gap, so it fails loudly if that behavior changes. The 90-minute boundary case now covers the earlier review concern.The failure message will not explain the cause. Consider naming the constant, for example
const detectorGapInflationSec = 342;. This makes a future mismatch easier to diagnose.

A return to sleep after a 60–90-minute awakening could be detected but omitted from the main night. Align final session grouping with the detector’s inclusive 90-minute continuation limit. Wake and unobserved gaps retain their classifications and do not inflate time asleep.
Grouped sessions must also stay within the existing 16-hour main-sleep span cap. A merge that would exceed it leaves separate valid groups available for selection.
