Without a pre-window sync, that window is often empty or thin when the band was offline overnight, silently degrading the baseline to the shipped 90-min median fallback. preSyncAt marks the instant ~45 min before the wake window opens at which a backfill sync should be triggered, so the baseline has real nocturnal data.

Same integration: keep-alive tick, RUN_ALARM early buzz, one-shot latch, fallback SET_ALARM untouched. Decision logic (lib/state/smart_wake.dart): - ConfounderProfile: journal-aware threshold adjustments from the day before the window. Alcohol/late caffeine → HR +4→6 bpm; stress/sick → ENMO 0.08→0.06g; workout → late-window 5→10 min; late meal → HR +4→5; alcohol+stress combo → no early buzz. All conservative, internal only (rough_night.dart guardrail). - enmoTrendExceeded (Q4): personalized movement trend — rising ENMO = turning over/arousal, not stable light sleep. Threshold = max(0.02g, medianENMO_3h × 0.5) × journalFactor. - lateWindowProtectionActive (Q3): no buzz in last 5/10 min if HR still within 2 bpm of baseline. Fallback fires at window end regardless. - percentileHr: 10th percentile of valid HR over last ~3h = nightly deep-sleep floor (matches #628 hr_min_night methodology). - likelyLightSleep v2: integrates all of the above. Backward compatible with identity profile (default thresholds = shipped v1 behavior). AppState._checkSmartWake (lib/state/app_state.dart): - Reads journal (tags + metrics) once per day, cached. - 10th-percentile baseline (primary) → yesterday's hr_min_night from day_result (secondary, #628 schema 60) → 90-min median (tertiary). - Passes profile + windowEnd/now/baselineHr into likelyLightSleep. - Confounder profile logged WITHOUT naming confounders (ethical guardrail).

Existing smart_wake_test.dart passes unchanged (identity profile = v1). No schema change. No new UI strings. No streaming cost increase. HRV/RMSSD deferred to v2 (Q5).

The 10th-percentile HR baseline (smart_wake v2) had no guaranteed data source when the wake window opened. Option C: extend the existing 61s band prompt lease to start at preSyncAt (= targetWake − 135min) instead of the window start (= targetWake − 90min). The band prompts every 61s from preSyncAt onward; each prompt triggers _startHistoricalRefresh() which backfills decoded_onehz. By the time the smart-wake window opens, the last ~3h of nocturnal data is in SQLite. Why not iOS BGTask/BGAppRefresh: opportunistic, never guaranteed (per existing code comment). Why not GPS keep-alive: battery drain + App Store rejection risk (Guideline 5.1.2). Why not local notification: iOS does not wake the app process for local notifications. Battery impact: ~45 extra 61s BLE wake cycles per night — negligible. Wire protocol: interval 61s, duration 8100s (135min) — within gen5's 28800s ceiling. Changes: - high_freq_wake_window.dart: preSyncLead constant (45min), effectiveLease getter (135min), shouldEnable covers preSyncAt → targetWake (was: windowStart → targetWake), both habitual + scheduled paths updated - app_state.dart: uses plan.effectiveLease ?? HighFreqWakeWindow.lease - Tests: 13 new in high_freq_wake_window_presync_test.dart + 2 updated in high_freq_wake_window_test.dart (pre-sync lead coverage) Safety invariant preserved: smart-wake DETECTION still only runs inside the actual window (inSmartWakeWindow check unchanged). The extended lease only affects DATA COLLECTION. Fallback SET_ALARM on the band untouched. Existing tests pass (verified by boundary analysis: tests at 04:00/02:00 still disabled, tests at 04:45 still enabled). --- lib/state/app_state.dart | 7 +- lib/sync/high_freq_wake_window.dart | 57 ++++-- test/high_freq_wake_window_presync_test.dart | 180 +++++++++++++++++++ test/high_freq_wake_window_test.dart | 23 ++- 4 files changed, 254 insertions(+), 13 deletions(-) create mode 100644 test/high_freq_wake_window_presync_test.dart diff --git a/lib/state/app_state.dart b/lib/state/app_state.dart index fb773faf9..22722b394 100644 --- a/lib/state/app_state.dart +++ b/lib/state/app_state.dart @@ -5732,7 +5732,12 @@ class AppState extends ChangeNotifier { smartWake: plan.shouldEnable && target != null ?

COMPILE ERROR: HighFreqWakePlan.effectiveLease referenced a bare `lease`, which is a static on HighFreqWakeWindow — not in scope on HighFreqWakePlan. Qualified it, and removed two locals (windowStart, scheduledStart) that the earlier lease change had left unread. 2. `enmoTrendExceeded` accepted `windowMinutes` and never read it. The documented alcohol/workout 5-minute smoothing was commentary only: the function always judged whatever list it was handed, and the caller always handed it 3 minutes. It now trims to the trailing `windowMinutes * 60` samples, and _checkSmartWake fetches max(3, trendWindowMinutes) minutes so a 5-minute window has 5 minutes to judge. Why the existing test missed it: the 5-minute spike test was SYMMETRIC — a spike centred in the list gives the same first-half and second-half means with or without slicing, so it passed either way. The new regression test is deliberately asymmetric: 2 min of high noise then a 3-min ramp, which only reads as a trend when the trailing 3 minutes are actually taken. Fetching longer must not make the detector more eager, so HR arousal and the mean-motion ceiling are now explicitly judged on the trailing 3 minutes (kHrWindowSamples = 180), with a test that a 5-minute recent list whose trailing 3 minutes sit at +2 bpm does not buzz. Local validation: Python mirror 63/63 (was 57; +4 regression, +2 HR window).

charset=UTF-8 Content-Transfer-Encoding: 8bit PR #630's medical disclaimer sits at the top of the sleep detail content, so at text scale 2.0 the hypnogram starts below the fold and the lazy ListView has not built it when _mount asserts findsOneWidget — the five (x2.0) sleep-hypnogram cases failed with 'Found 0 widgets'. Scroll the plot into view first when it is not built yet; the gesture assertions (scroll-vs-scrub routing, slop, marker placement) are unchanged. Verified locally on Flutter 3.41.6: graphs_scroll_first_scrub_test.dart 21/21 pass, shard 4 of 6 +1236 all passed, flutter analyze clean.
