PR Description: Masking Nap Detections during Validated Sleep Periods
Overview
This PR addresses the issue of "False Positive" nap detections occurring within validated night sleep periods in the OpenStrap/edge app.
Previously, the Nap detector (part of DerivationEngine) operated independently of the HMM-based sleep stager. This led to "Nap-Splits" where quiet periods during the night were incorrectly classified as separate naps, corrupting the main sleep session statistics.
Key Changes
Integration with SleepPipelineHMM: The Nap reconciliation logic now utilizes the validated onset_ts and wake_ts from the main sleep session.
Masking: Added a new filter napsWithoutMainSleep in nap_overlap_cleanup.dart that masks out any nap suggestions that overlap with the [mainOnsetSec, mainOffsetSec) window.
Architecture: Refactored DerivationEngine to pass the mainSleepPeriod context into the Nap processing flow, ensuring nap suggestions are logically reconciled against the sleep stage data before persistence.
Impact
Eliminates erroneous "nap" events during the night (e.g., the reported 147-minute nap).
Preserves the continuity of the main sleep session.
Enhances data integrity without removing manual user overrides.
PR Details
Issue: Activity detection splits main sleep into naps.
Solution: Masking Nap detection with HMM Sleep Windows.
Reconcile nap detection with validated main sleep and upgrade sleep and smart-wake analysis with personalized, conservative signal processing.
New Features:
Add HMM-based sleep staging and personalized smart-wake detection using nightly baselines, journal context, movement trends, and late-window protections.
Bug Fixes:
Prevent automatically detected naps from being persisted when they overlap the validated main sleep period.
Enhancements:
Extend smart-wake data collection before the active wake window to improve baseline availability.
Persist nightly heart-rate and HRV baseline values and surface an experimental sleep-analysis disclaimer.
Documentation:
Add user-facing medical disclaimer text for experimental sleep analysis.
Tests:
Add coverage for main-sleep masking, HMM sleep continuity, smart-wake personalization, and extended wake-window scheduling.
Summary by CodeRabbit
New Features
Sleep-stage classification now includes wake, light, deep, and REM stages. The sleep details screen displays a disclaimer noting that the experimental feature is not for medical decisions.
Smart Wake adjusts early-buzz decisions based on recent journal information, heart rate, and movement. It avoids early buzzing when data is insufficient or conditions suggest it may be disruptive.
High-frequency data collection can begin earlier ahead of habitual wake times and scheduled alarms.
Bug Fixes
Nap suggestions that overlap the main sleep period are filtered out before saving.
…e backfill
The smart-wake light-sleep detector (Phase 2 gate, all 8 questions
approved) computes a 10th-percentile HR baseline over the last ~3h of
decoded_onehz. 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. Pure additive field on HighFreqWakePlan; existing
callers that don't read it keep byte-identical behaviour.
…ndow
preSyncAt was computed but never consumed (dead code). 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).
Two defects reported by mikenrafter on PR OpenStrap#630, both mine:
1. 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).
Still not compiled — flutter analyze has not run.
The PR reconciles nap suggestions with validated main-sleep boundaries before persistence, while also introducing an experimental HMM sleep pipeline and broad Smart Wake v2 changes covering journal-aware thresholds, personalized baselines, movement/protection guards, and extended data collection.

Uses a three-hour 10th-percentile HR baseline with day-result and median fallbacks, while preserving the fallback alarm behavior.
Adds movement-trend suppression, late-window deep-sleep protection, and extended high-frequency lease planning before the smart-wake window.
Adds unit coverage for confounder handling, trend detection, protection logic, baseline calculation, and 135-minute lease behavior.
Adds regression coverage for HMM stage continuity across brief arousals.
Verifies that a one-epoch arousal does not leave subsequent deep sleep classified as light sleep.

The PR adds HMM-based sleep-stage classification, filters nap suggestions that overlap the main sleep period, and updates Smart Wake with journal-derived thresholds, baseline heart-rate handling, and expanded wake-window timing. It also adds sleep-baseline database columns and an experimental-use disclaimer to the sleep-detail loading view.
Changes: Nap suggestion filtering
Layer / File(s)
Summary
Shared nap overlap filtering lib/compute/nap_overlap_cleanup.dart, lib/compute/derivation_engine.dart
Nap filters use shared interval logic. Before reconciliation, suggestions that overlap the main sleep period are removed when that period is available. Workout reconciliation is unchanged.
HMM sleep-stage classification
Layer / File(s)
Summary
Sleep-stage model and decoding lib/compute/sleep_pipeline_hmm.dart
The new analyzer computes heart-rate and RMSSD baselines, calculates state emission probabilities, and decodes sleep states using configured transition probabilities. The code labels the analyzer as experimental and not for medical use.
Pipeline integration and disclaimer lib/compute/onehz_pipeline.dart, lib/l10n/app_en.arb, lib/ui2/screens/sleep_detail.dart
The one-hertz pipeline maps decoded states to stage labels and recognizes nrem as a sleep stage. The sleep-detail loading view displays a localized disclaimer.
Smart Wake adaptation
Layer / File(s)
Summary
Confounder profiles and detection rules lib/state/smart_wake.dart
Journal inputs determine profile thresholds and rules. The detector also checks recent samples, rising movement, and late-window protection.
Journal and heart-rate baseline inputs lib/data/db.dart, lib/state/app_state.dart
Database setup and repair add nullable sleep-baseline columns. Smart Wake loads journal inputs and uses a three-hour heart-rate window, with the described fallbacks for its baseline.
Wake-window timing and request lease lib/sync/high_freq_wake_window.dart, lib/state/app_state.dart
Wake plans include pre-sync times and effective leases. Habitual-wake and scheduled-alarm plans enable from 135 minutes before their target, and Smart Wake uses the effective lease when available.

</issue_to_address>
Sourcery assessment
Needs a human reviewer. 2 findings to address first, and the revised smart-wake detector can trigger the band to buzz before the scheduled wake time; if its thresholds or signal interpretation are wrong, a user can be woken early, and reverting cannot undo that night’s lost sleep. The impact is bounded to affected wake windows rather than persisted data or an unbounded policy outcome.

Review comments at @lib/compute/derivation_engine.dart:
- Line 5730: Update the main sleep period lookup to read `sleep_periods` from
`blocks.bundlePatch` instead of `blocks.wake`, so the mask is available during
nap suggestion reconciliation.
- Line 5744: Update the nap reconciliation flow around napsWithoutMainSleep and
activityStore.reconcile to supersede pending nap suggestions that overlap a
validated main sleep period, including when that period removes the nap and
leaves no reconciliation candidate. Leave decided suggestions unchanged.
- Around line 5728-5744: Update kAlgoVersion to 114 for the nap-output change
and add the required changelog entry immediately above the constant so finalized
days are re-derived.
Review comments at @lib/compute/onehz_pipeline.dart:
- Around line 2292-2308: Remove the unused _classifySleepStagesHMM function so
it cannot imply that decoded stages affect persisted or displayed results; do
not wire it into the existing hypnoStages path.
Review comments at @lib/compute/sleep_pipeline_hmm.dart:
- Around line 61-64: Update the `computeBaseline` collection logic for `hrs` and
`rmssds` to read `hr` and `rmssd` as nullable numbers, skip missing or null
values, and retain the existing valid-value range filters so one incomplete
epoch does not abort baseline computation.
- Around line 73-76: Expose baseline availability from the HMM using
`hrMinNight` and `rmssdMeanNight`, and have the caller skip HMM staging when
either baseline is missing. Preserve the existing decoding path when both
baselines are available.
- Around line 113-116: Update viterbiDecode to read each epoch’s isContactLost
flag and pass it to _getEmissionLogProb for both the initial epoch and
subsequent epochs, ensuring contact-lost measurements receive the neutral
emission.
Review comments at @lib/state/app_state.dart:
- Line 4488: Update the confounder profile log at the _log call to report only
the cache day and whether the profile is identity; omit the numeric profile and
any values that reveal active confounders.
- Around line 4550-4551: Update the baseline query flow around
baselineWindowStart and baselineWindowEnd so it does not reread and process the
full three-hour window on every tick. Cache the baseline percentile and ENMO
median for a few minutes, refreshing from the recent window between cache
updates, while preserving the existing calculations in likelyLightSleep.
Review comments at @lib/state/smart_wake.dart:
- Line 203: Preserve the class’s “never less conservative” contract by changing
the lateMealActive adjustment so it does not raise trendFactor above its
baseline; also correct the trendThresholdFactor documentation to state that a
factor below 1 lowers the threshold, allowing smaller rises to block a buzz.
Review comments at @lib/sync/high_freq_wake_window.dart:
- Around line 18-19: Update the `preSyncAt` documentation in the
`HighFreqWakeWindow` class to clarify that it may be set even when the plan is
disabled; only the insufficient-history plan leaves it null. Do not describe
null as a disabled-plan signal.
Review comments at @lib/ui2/screens/sleep_detail.dart:
- Around line 524-534: Move the disclaimer declaration below the
`AppLocalizations.of(c)` assignment in the `build` method so `l` is declared
before `disclaimer` uses it; leave unrelated styling and layout unchanged.
- Around line 526-529: Move the sleep medical disclaimer out of the `_loading &&
_d == null`-only branch and ensure it remains visible in the loaded night view,
positioned above the hypnogram. Preserve its visibility during loading if that
branch currently displays it.

Read the main sleep period from blocks.bundlePatch.
_computeDayBlocks writes sleep_periods to bundlePatch. The wake map contains activity features, not sleep periods. This lookup therefore yields null, and every nap suggestion reaches reconciliation without the new mask. Read blocks.bundlePatch['sleep_periods'] instead. (raw.githubusercontent.com)

Supersede stale pending nap suggestions.
When napsWithoutMainSleep removes a previously persisted nap, reconcile receives no candidate for that interval and performs no update. The pending row can therefore remain visible for up to seven days. Supersede only overlapping pending nap rows when a validated main sleep period is available. Keep decided suggestions unchanged.

Remove or complete _classifySleepStagesHMM.
_classifySleepStagesHMM has no caller, so its decoded stages do not reach persisted or displayed results. The stager output's 'epoch_sec': 1 does not establish the cadence of this function's epochData; it is produced from the existing d.hypnoStages path.
If this classifier is wired in, derive the 120-minute sample count from the actual epoch duration. Also pass isContactLost into the emission calculation. viterbiDecode currently reads only hr and rmssd, so the added key has no effect.

computeBaseline throws on epochs without hr or rmssd.
(d['hr'] as num) and (d['rmssd'] as num) throw a TypeError when the key is missing or null. viterbiDecode reads the same keys with as num? and ?? 0.0, so the two methods disagree about what valid input is. One epoch with a null rmssd aborts baseline computation for the whole night. RMSSD is often absent in sparse windows.
Use the nullable form and skip the epoch.

The 3-hour baseline query runs every 30 s on the main isolate.
During the smart-wake window each tick reads up to about 10,800 rows. It builds SmartWakeSample objects, sorts for the percentile, and computes ENMO over the whole list in likelyLightSleep. The doc for onehzHrAccelBetween in db.dart says every caller passes a window of up to about 90 minutes. This change doubles that.
The baseline changes slowly. Cache the percentile and ENMO median for a few minutes and refresh only the recent window each tick. Alternatively, compute the percentile in SQL.

The late meal factor of 1.5 breaks the "never less conservative" contract.
The class documentation (lines 78-80) says every adjustment can only make early buzz less likely. A trendFactor of 1.5 raises the trend threshold, so a rising ENMO is blocked less often. That makes a buzz more likely.
The documentation for trendThresholdFactor (lines 112-114) is also wrong for stress and sick. A factor of 0.5 lowers the threshold, so smaller rises block the buzz. The comment says "only large transitions count", which is the opposite.
Decide whether late meal may loosen the trend check. Then correct either the code or the documentation.

Preserve the class’s “never less conservative” contract by changing the
lateMealActive adjustment so it does not raise trendFactor above its baseline;
also correct the trendThresholdFactor documentation to state that a factor below
1 lowers the threshold, allowing smaller rises to block a buzz.

The preSyncAt documentation is wrong.
The comment says preSyncAt is null when the plan is disabled. planFromRows always sets preSyncAt on the habitual plan, including when shouldEnable is false. Only the insufficient-history plan leaves it null. Correct the comment so callers do not rely on null as a "disabled" signal.

The disclaimer is hard to read, uses a deprecated API, and shows only while loading.
Colors.amber.withOpacity(0.1) is deprecated in current Flutter. Use withValues(alpha: 0.1).
Amber 10 px text on a 10 % amber tint has low contrast, especially on a light theme. The rest of this file solves contrast with P.of(c).on(...) and F.over. A fixed fontSize: 10 also ignores the design tokens.
The disclaimer is added only to the _loading && _d == null branch. It disappears as soon as the night renders, so users who see staged sleep never see the warning.
Decide where users must see this text, such as the loaded night view above the hypnogram. Use theme tokens for style. The fix in the previous comment covers the token and API changes.

Headless Smart Wake sends the fixed 90-minute lease, not plan.effectiveLease.
For habitual and scheduled-alarm plans, preSyncAt is targetWake minus 135 minutes. The headless call at background_sync.dart:227-234 passes duration: HighFreqWakeWindow.lease (90 minutes). The band therefore stops prompting 90 minutes after the enter command. If that command is sent early in the pre-sync lead, the final part of the planned interval, up to 45 minutes before targetWake, has no prompt coverage. The app still records _highFreqUntil = targetWake, so it does not know the band stopped early.
The foreground path already sends the full interval. app_state.dart:5044 passes plan.effectiveLease ?? HighFreqWakeWindow.lease to the same engine method. The headless path should use the same expression.

PR Description: Masking Nap Detections during Validated Sleep Periods
Overview
This PR addresses the issue of "False Positive" nap detections occurring within validated night sleep periods in the
OpenStrap/edgeapp.Previously, the Nap detector (part of
DerivationEngine) operated independently of the HMM-based sleep stager. This led to "Nap-Splits" where quiet periods during the night were incorrectly classified as separate naps, corrupting the main sleep session statistics.Key Changes
