User description

Stacked on #258 — review that one first, this targets it so the diff here is only the new work.

Everything he asked for after the audit, plus two bugs found on the way in.

the dead end

forget the band and there was no way back to pairing. MyDevicesView decided whether to draw the pair affordance from sources.isEmpty, but that list is built from two independent conditions — isPaired adds the band, phoneStepsEnabled adds a phone. Forgetting the band cleared only the first, so the phone's steps row kept the list non-empty, the empty-state card never rendered, and that card carried the only onPair callback in the app. Skipping pairing and then turning on phone steps produced the same [phone] list and the same hidden button.

Found on the way: unpair() cleared paired and the PairedDevice row and nothing else. The engine holds one DeviceState for the process lifetime and band.strap_name lives in prefs, so pairing a different band inherited the old one's name, serial, battery, bond verdicts and generation — which every sensor-dependent metric keys its constants off. DeviceState.reset() now runs on unpair.

imported days were setting the baseline they're supposed to stay out of

The rule was enforced on the write path only. _BaselineHistoryCache.load() read metric_series with no source filter, and both importers write real series rows through putDayResult — so rhr, rmssd, readiness and resp_rate were partly set by somebody else's algorithm. The other four escaped by accident: the importers happen to write skin_temp_z, not skin_temp_adc.

NOOP is not foreign — NoopIngest holds a DerivationEngine and feeds it reconstructed 1 Hz substrate, so those days are our own maths. Only whoop_export and cloud_v2 are.

source is NULL for every pre-v43 day and the backfill deliberately never fills it, so filtering on source = 'band' would have traded a pollution bug for a data-loss one. Both importers also put imported: true in the day bundle, which is what the write path has always tested, so old days are decidable anyway. importedDates() is the union of both eras.

trailingSeriesValues defaults to measured-only (it exists to build rolling baselines); metricSeries defaults to including imports. A picture may splice two algorithms, a statistic may not.

kAlgoVersion 76. Strict no-op for anyone who never imported.

screens didn't notice writes landing under them

Two halves, and fixing either alone still looks broken. The importers called notifyListeners() and never bumped the revision — Home's own comment already named the hole. And of the five tabs the shell keeps alive forever in an IndexedStack, only Home and Workouts listened.

Fixed on Health (and its sub-tabs, which cached on != null — the same bug one level down), Nutrition, Wellness, Cycle. Home and Workouts moved onto a shared RevisionReload mixin, deleting ~50 lines of duplicated plumbing.

It rides the ValueNotifier, not the ChangeNotifier path, so nothing repaints — notifyListeners() fires at ~1 Hz with live HR and is untouched. Pinned test: five notifyListeners() in a row produce zero extra reads.

widgets

The palettes were already ui2; the content model wasn't. The face was Strain · Sleep · HRV — the pre-rebuild home. It's Recovery · Strain · Sleep now, matching RingTrio, arcs painted through P.on(accent) (computed by running the real solver, which caught three hardcoded values already slightly off).

It printed a held-over night as today's. getToday serves the last night that scored until today's settles; Home refuses those and the widget didn't, so every morning before the first sync you saw the night-before-last as this morning. And every absence was one dimmed circle — Home has four ring states, the widget had one, and the two that carry the reason live in a Metric.note that never crossed the App Group.

New: Last night (sleep + efficiency, nightly-stable so the refresh budget can't make it wrong) and Overnight (HRV against your own baseline + resting HR — HRV left the home rings in the rebuild, this is where it went). Steps and day strain rejected: they accrue all day but only move on a derive, and a step count reading low is a wrong number, not a missing one.

iOS extension builds; target membership proved by injecting a type error, watching it fail, reverting. Sentinels 14 → 21.

prompts to log

Medication — the only prompt whose time isn't a guess. The schedule model already existed (med_def.schedule_json, slotsForDay()) and nothing in lib/notify/ had ever read it. Only a dose still upcoming arms. Names no drug — it lands on a lock screen.

Daily check-in — one prompt for the whole journal, an hour before the bedtime the sleep coach already learned, floored at 17:00, refusing to arm inside quiet hours.

Both off by default. Rejected: food (the timing model needs a history that only exists once you already log reliably), water (water_ml is hasTime: false, so neither "already drank" nor "done" is answerable), post-workout rating (already inline while you're holding the phone).

double-tap

The engine shipped long ago — decode, recency and debounce guards, persisted mapping, both native channels — and the picker died with lib/ui. So the mapping sat on none with nothing able to move it. Restored under Settings › Automation, plus a log water action. The list is what capabilities() says this phone can do, so volume and Tasker never appear on iOS.

trend arrows

Sparkline → arrow on the overview tiles. A direction only counts if it clears half a standard deviation of the baseline; inside that it's steady, and under 7 recorded values there's no arrow at all with the reason in the semantics label, because a flat arrow claims a measured "no change". Polarity is per metric — respiratory rate deliberately unjudged. Orange rather than red: C.red is already the heart's category colour in MetricRow.


Goldens fail in CI as always (test/goldens/ is gitignored). 3161 pass, 53 golden failures, nothing else.

Known, not fixed here: StartCard throws a RenderFlex assert when the Workouts tab is pumped headlessly — debug-only, which is why it ships, but it makes that tab untestable.

Description

  • Fix dead-end after forgetting a band: pair button now gates on band presence, not source list emptiness; unpair resets DeviceState and clears strap name so a re-pair with a different band doesn't inherit the old one's identity, generation, or bond verdicts.

  • Fix imported days (WHOOP/cloud) polluting readiness/illness baselines: trailingSeriesValues now excludes imported dates by default; metricSeries gains a measuredOnly flag; pre-v43 NULL-source days are resolved via the "imported":true bundle flag rather than dropped.

  • Add medication and daily check-in notification prompts (both off by default): one notification per upcoming dose (no drug name on lock screen), one evening check-in suppressed once any rating is written; notification settings screen now routes through AppState so the med schedule and journal state are available.

  • Replace sparklines on metric rows with a statistical trend arrow (Cohen's d ≥ 0.5 SD threshold); widget service now resolves all three home rings (Recovery/Strain/Sleep) in Dart with calibration-progress and held-over-overnight states; Sleep and Overnight widgets added and reloaded together with the main widget.

the pair button lived inside `sources.isEmpty` and the phone is a source, so
one steps row was enough to hide it. gate it on whether there's a BAND, and
put it at the top where the missing band would sit — a phone pedometer is not
a substitute for one and the screen now says so. same dead end for anyone who
only ever had phone steps and never paired.

while in there: forgetting now drops what the old band said about itself.
the engine keeps one DeviceState for the life of the process and the strap
name is in prefs, so a re-pair with a DIFFERENT band inherited its name,
serial, generation and bond verdicts — including an autoReconnectPaused that
would have quietly paused the loop for the new one. generation is the one
that matters: the device page states it as a calibration fact.

driven through the real screen over a real AppState, because both halves look
fine on their own.
nothing in the app ever asked — you had to remember to open it.

meds come off the schedule you already typed in, one notification per
dose still due (a dose marked taken or skipped is never armed), and the
notification names no drug: that lands on a lock screen.

check-in is one prompt for the whole self-report, an hour before the
bedtime the coach learned, and it's skipped once the day has a rating in
it. both off by default, both on schedulableIds so they can actually
fire, both land on a screen that exists.
and the notification screen reschedules through appstate — calling the centre
directly cancels what you turned off and arms nothing back, so meds stayed
silent until the next foreground pass.
isMeasuredDay only ever guarded the write path. metric_series reads had
no filter, so a whoop/cloud import's rhr, rmssd, readiness and resp_rate
rows went straight into the readiness + illness window.

can't filter on metric_series_version.source alone — it only exists from
v43 and is never retro-filled, so every older day reads NULL and dropping
those would delete the real early history instead. NULL is decidable
though: the bundle behind the day still carries "imported":true, which is
the same flag isMeasuredDay tests. so the mask is both signals unioned,
in LocalDb.importedDates.

trailingSeriesValues defaults to measured-only now (it exists to build a
baseline), which also fixes the live rhr anchor without touching
app_state. journal insights and the weekday permutation test filter too —
a chart may splice two algorithms, a statistic may not.
the widgets were left behind by the ui2 rebuild. the home face was a
readiness headline over strain · sleep · hrv, which is the OLD home
screen — home has three rings now (recovery · strain · sleep), the icon
inside the dial and the number under it. so does the widget.

the bigger thing: an absence used to be a dimmed empty circle. "four
more nights and this fills in" and "the band recorded nothing all
night" were the same picture, forever, because the calibration counts
and the pipeline's reason live in a metric's note and the note never
crossed the app group. push() resolves all four ring states now
(measured / calibrating / unscaled / absent) exactly like RingTrio, and
swift + kotlin just draw them. deletes the ring maths from both natives
rather than adding to them.

also: home refuses an overnight block that belongs to an earlier night
instead of printing it in the today slot. the widget didn't, so every
morning before the first sync the home screen showed the night before
last's recovery as today's. it refuses it now and publishes the reason
in its place.

new widgets, both small + all three lock screen families:

  last night — the sleep ring at full size plus efficiency. the number
  people look for before they open anything, at the moment the lock
  screen is already up.
  overnight — hrv against your own baseline, and resting hr. hrv left
  the home rings in the rebuild; this is where it went, and it's a
  better home for it than a third of a card.

rejected: steps and day strain. both accrue all day and only move on a
derive, and widgetkit's reload budget throttles us well under that — a
step count reading low is a wrong number, not a missing one. battery
already has a widget.

arcs now spend P.on(accent) like the app's do, not raw pigment, and the
numerals are sf pro text tabular rather than rounded. android gets the
same three dials with the icon drawn into the bitmap.
imports never bumped insightsRevision, and health/nutrition/wellness/cycle
never listened to it at all — the shell keeps those tabs alive forever, so
leaving the tab and coming back was the only way to see an import. home and
workouts had each hand-rolled the same twenty lines around the same notifier,
so that's a mixin now (RevisionReload) and everyone uses it.

signal stays on the ValueNotifier, not notifyListeners — that one ticks at 1 hz
with live hr and watching it broadly is the slow-app bug, not the stale-screen
one.

also: overview rows show a direction arrow instead of the 52pt sparkline you
couldn't read a number off. only claims a direction when the last 3 days clear
half an sd of the 14 behind them, nothing at all under a week of data, and
green/orange is per metric (rhr down is good, hrv down isn't) with the arrow
carrying the direction on its own.
it's a detection, not a chart — the night gets called rough by comparing it
against the spread behind it, and imported days were setting that spread.
no-op if you never did: the imported-days set is empty and every read is the
same. days already finalized keep what they were derived with, raw is long
pruned.

🧪 PR contains tests
🔒 No security concerns identified
⚡ Recommended focus areas for review

Inline subquery in WHERE

metricSeries and trailingSeriesValues now embed _importedDatesSql directly inside a NOT IN (...) clause. _importedDatesSql itself contains a LIKE '%"imported":true%' scan over day_result.payload_json (whole day bundles). Every call to either method with measuredOnly: true — including every baseline read in _BaselineHistoryCache.load() — now runs this full-table scan inline. trailingSeriesValues defaults measuredOnly: true, so this fires on every baseline read during derivation. For a user with years of history this is an unbounded synchronous scan inside Isolate.run, but more critically metricSeries is also called from the UI isolate in local_repository_impl.dart for sparklines. If any of those call sites pass measuredOnly: true (or if a future caller does so by accident given the default on trailingSeriesValues), this becomes heavy synchronous work on the UI isolate — the exact ANR pattern documented in §4.4. A materialized imported_dates table or a one-time importedDates() call whose result is passed in would avoid the repeated scan.

where: 'key = ? AND value IS NOT NULL'
    '${measuredOnly ? ' AND date NOT IN ($_importedDatesSql)' : ''}',
whereArgs: [key],
orderBy: 'date ASC',
limit: limit,
Column alias mismatch

importedDates() casts every row's date column directly to String with r['date'] as String. The comment above the SQL notes that SQLite does not enforce NOT NULL on a declared PRIMARY KEY column of a legacy rowid table, and the IS NOT NULL guards in the SQL protect the NOT IN predicate — but the Dart-side cast happens after the query returns. If a NULL date somehow survives into the result set (e.g. from the day_result half of the UNION where the guard is r.day_id IS NOT NULL but r.day_id is the alias, not date), the cast throws a TypeError at runtime, silently caught nowhere, and the caller gets an exception rather than a set. The day_result half selects r.day_id aliased as nothing — it lands in the map as r.day_id, not date — so the Dart cast r['date'] as String would return null for those rows and throw. The column alias should be explicit: r.day_id AS date.

    'SELECT r.day_id FROM day_result r '
    '$_servedDayJoin '
    "WHERE r.day_id IS NOT NULL AND r.payload_json LIKE '%\"imported\":true%'";

/// Day labels whose stored scalars are ANOTHER vendor's derived numbers.
///
/// THE MASK for every baseline read, and the inverse of [isMeasuredDay]:
/// that one guards the WRITE path (an import must not clobber a measured
/// day), and nothing guarded the read path — so imported days were feeding
/// the readiness and illness baselines the user's own scores are measured
/// against. A window that mixes them is not a baseline of this person.
///
/// Returned as a set rather than applied inside each query on purpose: the
/// scan behind it is over `day_result.payload_json` (whole day bundles), so

static Future<Set<String>> importedDates() async {
  final db = await instance;
  return {
    for (final r in await db.rawQuery(_importedDatesSql)) r['date'] as String,
  };
}
checkInSlot suppression logic

checkInSlot suppresses the prompt when doneToday && t > nowMin, meaning "today is written AND the slot is still in the future". The intent is to avoid re-arming a prompt for a day already answered. However, when t <= nowMin (the slot has already passed today) and doneToday is true, the method returns t and arms tomorrow's instance — which is correct. But when doneToday is false and t <= nowMin, it also returns t, arming a one-shot for a time that has already passed today. scheduleOnce will then fire immediately or be silently dropped depending on the platform's behavior for past instants. The existing water-slot and weekly-recap paths avoid this by computing nextDailyInstant, but _armCheckIn passes minuteOfDay directly to svc.nextDailyInstant — so the instant itself is always tomorrow-or-later. The slot value t is a minute-of-day, not an absolute instant, so the suppression condition is comparing apples to oranges: t > nowMin is "the slot minute is later than the current minute", which is true even if the slot already fired earlier today and the user just opened the app at 21:05 with a 20:30 slot. This means a user who opens the app after their check-in time but before midnight, with today unanswered, gets a prompt armed for tomorrow's 20:30 — which is correct — but the suppression path for doneToday at the same time of day also correctly skips it. The logic is accidentally right but the reasoning is fragile; a future caller passing an absolute minute could break it silently.

static int? checkInSlot(
  NotificationPrefs prefs,
  double? bedtimeMinOfDay, {
  required bool doneToday,
  required int nowMin,
}) {
  final t = checkInMinute(prefs, bedtimeMinOfDay);
  if (t == null) return null;
  if (doneToday && t > nowMin) return null; // would land today, already asked
  return t;
}
frac saved as double for absent ring

In _reloadSnapshotWidgets-adjacent wipe path (wipe()), absent rings are written with ring_${r}_frac as -1.0 (a double). In the push() path, _Ring stores frac as a double and HomeWidget.saveWidgetData<double>('ring_${r.key}_frac', r.frac) is called. When _gapRing returns a calibrating ring (state 1), frac is (counts.have / counts.need).clamp(0.0, 1.0) — correct. But when it returns a state-2 absent ring, frac defaults to -1 via the constructor (frac == null ? -1 : frac.clamp(...)). The native readers on both iOS and Android must therefore handle -1.0 as "no arc" for state 2 but a real sweep for state 1. This is a contract between Dart and native code that is not enforced anywhere in the diff — if a native reader interprets -1.0 as a sweep value rather than a sentinel, it draws a backward arc. This is not verifiable from the Dart diff alone, but given the history of widget rendering regressions in this codebase (§4.11) it warrants explicit confirmation that all four native targets (iOS widget, Android widget, Watch, Siri) handle the -1.0 sentinel consistently.

  await HomeWidget.saveWidgetData<double>('ring_${r.key}_frac', r.frac);
}

Possible issue
Mixin subscription never fires without super call

RevisionReload.didChangeDependencies subscribes to insightsRevision and calls
reload() when it moves, but WorkoutScreen overrides didChangeDependencies without
calling super.didChangeDependencies(). This means the mixin's subscription logic
never runs, so reload() is never triggered by revision changes and the screen still
only loads once.

lib/ui2/screens/workout_screen.dart [56-64]

 @override
 void didChangeDependencies() {
   super.didChangeDependencies();
   // `_load ??=` alone meant the screen read the database exactly once, for
   // the life of the widget — so a session you had just finished was absent
   // from History, "This week", "Tracked" and the weekly load until the app
   // was restarted. `RevisionReload` re-reads when the data moves: the manual
   // finish, the gesture path, the Live Activity and an import alike.
-  _load ??= _loadWorkoutData(context.read<AppState>());
+  if (_load == null) {
+    _load = _loadWorkoutData(context.read<AppState>());
+  }
 }
Suggestion importance[1-10]: 9

__

Why: The RevisionReload.didChangeDependencies mixin method subscribes to insightsRevision, but _WorkoutScreenState.didChangeDependencies calls super.didChangeDependencies() first and then sets _load ??=. Looking at the code, super.didChangeDependencies() IS called on line 57, which chains to the mixin's didChangeDependencies. This is actually correct behavior — the mixin's subscription logic runs via super. However, the suggestion's improved_code changes _load ??= ... to an if (_load == null) block, which is functionally identical and doesn't fix any real issue. The suggestion misidentifies the problem since super.didChangeDependencies() is already called.

Fix crash setting views on wrong layout root

When !w.fresh(widgetData) the no-data RemoteViews is built from
widget_openstrap_nodata, which does not contain R.id.widget_root. Calling setInt and
setOnClickPendingIntent on that view after the if/else block will throw a
RuntimeException at render time. The background and tap intent must be set inside
each branch, on the correct layout, as OvernightWidgetProvider already does for the
text colours inside the no-data branch.

android/app/src/main/kotlin/wtf/openstrap/openstrap_edge/OvernightWidgetProvider.kt [80-82]

Suggestion importance[1-10]: 7

__

Why: The widget_openstrap_nodata layout may not contain R.id.widget_root, so calling setInt and setOnClickPendingIntent after the if/else block could throw a RuntimeException. However, it's possible that widget_openstrap_nodata does include R.id.widget_root (as it's a common pattern), making this a conditional issue rather than a guaranteed crash.

Prevent crash drawing icon onto immutable bitmap

ringBitmap returns a hardware-backed or already-recycled bitmap on some API levels;
drawing onto it via Canvas(bmp) requires a software-backed mutable bitmap. If
ringBitmap returns an immutable bitmap, Canvas(bmp) will throw
IllegalStateException: Software rendering doesn't support hardware bitmaps. The icon
should be drawn onto a fresh mutable copy of the bitmap.

android/app/src/main/kotlin/wtf/openstrap/openstrap_edge/StrapWidgets.kt [234-252]

 fun dialBitmap(
     context: Context,
     sizeDp: Int,
     strokeDp: Float,
     trackColor: Int,
     color: Int,
     t: Double,
     iconRes: Int,
 ): Bitmap {
-    val bmp = ringBitmap(context, sizeDp, strokeDp, trackColor, color, t)
-    val icon = ContextCompat.getDrawable(context, iconRes) ?: return bmp
+    val ring = ringBitmap(context, sizeDp, strokeDp, trackColor, color, t)

     val px = bmp.width
     val side = (px * 0.34f).toInt().coerceAtLeast(1)
     val left = (px - side) / 2
     icon.setBounds(left, left, left + side, left + side)
     icon.setTint(color)
     icon.draw(Canvas(bmp))
     return bmp
Suggestion importance[1-10]: 6

__

Why: Drawing onto a bitmap via Canvas(bmp) requires a mutable, software-backed bitmap. If ringBitmap returns an immutable bitmap, this would throw an IllegalStateException. Copying to a mutable bitmap before drawing is a valid defensive fix, though ringBitmap likely already creates a mutable bitmap via Bitmap.createBitmap.

Guard against NaN standard deviation with single-element baseline

When base.length == 1, the variance denominator is base.length - 1 == 0, producing
sd = NaN. The subsequent comparison delta.abs() <= 0.5 * NaN is always false, so a
single-element baseline always reports a direction instead of Trend.steady. Guard
against this by returning Trend.steady when sd is zero or NaN (a single-element
baseline has no spread to compare against).

lib/ui2/grammar.dart [1127-1130]

 final sd = math.sqrt(
     base.map((x) => (x - mb) * (x - mb)).fold<double>(0, (a, b) => a + b) /
         (base.length - 1));
-if (delta.abs() <= 0.5 * sd) return Trend.steady;
+if (!sd.isFinite || sd == 0 || delta.abs() <= 0.5 * sd) return Trend.steady;
Suggestion importance[1-10]: 4

__

Why: The concern about base.length == 1 causing division by zero is valid in theory, but the code requires v.length < recentN + baseMin (3 + 4 = 7) to return null, meaning base will always have at least baseMin (4) elements. So base.length - 1 is always at least 3, making the NaN case impossible in practice. The suggestion is technically incorrect given the existing guard. Additionally, the improved_code changes the behavior for sd == 0 (a flat baseline), which the code's own comment explicitly says should NOT abstain.

Low
Avoid table alias collision in embedded subquery

The first branch of the UNION selects days from metric_series_version where source
IS NOT NULL AND source <> 'band'. However, a pre-v43 measured day that was later
re-derived by the band will have its metric_series_version.source updated to 'band'
and be correctly excluded. But a pre-v43 imported day that was later re-derived by
the band would also get source = 'band' and fall through to the day_result half —
which correctly catches it via the "imported":true payload. The concern is the
reverse: a day where metric_series_version.source is a foreign vendor but day_result
has no "imported":true flag (e.g. written by a future importer that forgets the
flag). The UNION already handles this correctly. However, the day_result half uses
$_servedDayJoin which filters to the current algo_version — but _importedDatesSql is
also used inside trailingSeriesValues via a subquery, where _servedDayJoin
references a table alias r that is already defined in the outer query context.
Verify that $_servedDayJoin does not introduce a conflicting alias r when embedded
as a subquery inside trailingSeriesValues's rawQuery, as a duplicate alias would
cause a SQL error at runtime.

lib/data/db.dart [6134-6140]

 static const String _importedDatesSql =
     'SELECT date FROM metric_series_version '
     "WHERE date IS NOT NULL AND source IS NOT NULL AND source <> 'band' "
     'UNION '
-    'SELECT r.day_id FROM day_result r '
-    '$_servedDayJoin '
-    "WHERE r.day_id IS NOT NULL AND r.payload_json LIKE '%\"imported\":true%'";
+    'SELECT dr.day_id FROM day_result dr '
+    '${_servedDayJoin.replaceAll(' r ', ' dr ').replaceAll(' r.', ' dr.')} '
+    "WHERE dr.day_id IS NOT NULL AND dr.payload_json LIKE '%\"imported\":true%'";
Suggestion importance[1-10]: 2

__

Why: The suggestion asks to verify a potential alias collision, but the improved_code uses string replacement on _servedDayJoin which is a fragile approach and may not correctly handle all occurrences. Additionally, _importedDatesSql is used as a subquery (via NOT IN (...)) in metricSeries and trailingSeriesValues, where the outer query uses different table names, not r, so a collision is unlikely. The suggestion is speculative and the proposed fix is error-prone.

Low
Revision listener leaks on dispose

_WellnessScreenState.dispose removes the tab-request listener but does not call
super.dispose() last — it does, but it also does not call the RevisionReload mixin's
dispose, which removes the _rev listener. Since RevisionReload defines its own
dispose that must be called via super.dispose(), and _WellnessScreenState overrides
dispose without the mixin's cleanup being chained, the _rev listener leaks and
_onRevision can fire on a dead state. The mixin's dispose is only reached if
super.dispose() chains through it, which requires the mixin to be listed correctly
in the MRO — verify that super.dispose() in _WellnessScreenState.dispose actually
reaches RevisionReload.dispose before State.dispose.

lib/ui2/screens/wellness_screen.dart [125-128]

 @override
 void dispose() {
   WellnessScreen.tabRequest.removeListener(_onTabRequest);
+  _rev?.removeListener(_onRevision);
   super.dispose();
 }
Suggestion importance[1-10]: 2

__

Why: In Dart mixins, super.dispose() in _WellnessScreenState.dispose correctly chains through RevisionReload.dispose before reaching State.dispose due to mixin linearization. The mixin's dispose is not bypassed — it is part of the MRO chain. The suggestion's concern about listener leaks is unfounded given correct mixin usage, and the improved_code adds a redundant explicit _rev?.removeListener(_onRevision) call that would double-remove the listener.

General
Fix quiet-hours cap missing for same-day quiet windows

The quiet-hours cap is only applied when quietStartMin > quietEndMin (an overnight
window, e.g. 22:00–07:00). A same-day quiet window (e.g. 12:00–23:00, where
quietStartMin < quietEndMin) never has its cap applied, so the check-in can be
scheduled inside it. The final prefs.inQuietHours(t) call will catch it and return
null, but only after checkInEarliestMin may have pushed t back into the window. The
cap should be applied whenever quiet hours are enabled and the computed time falls
after quietStartMin.

lib/notify/notification_center.dart [490-505]

 static int? checkInMinute(NotificationPrefs prefs, double? bedtimeMinOfDay) {
   if (!prefs.checkInEnabled) return null;
   var t = bedtimeMinOfDay == null
       ? checkInFallbackMin
       : bedtimeMinOfDay.round() - checkInBeforeBedMin;
-  if (prefs.quietEnabled && prefs.quietStartMin > prefs.quietEndMin) {
+  if (prefs.quietEnabled) {
     final cap = prefs.quietStartMin - 30;
     if (t > cap) t = cap;
   }
   if (t < checkInEarliestMin) t = checkInEarliestMin;
   if (prefs.inQuietHours(t) || t >= 24 * 60) return null;
   return t;
 }
Suggestion importance[1-10]: 3

__

Why: The suggestion identifies a real asymmetry in the cap logic, but the final prefs.inQuietHours(t) guard already catches and returns null for any time inside the quiet window. The cap is an optimization to avoid pushing t back into the window via checkInEarliestMin, but the existing fallback handles the correctness case. The impact is minor and the suggestion's improved_code could cause unintended capping for same-day windows where the cap itself might be negative or before checkInEarliestMin.

Low
Failure path boolean latch never reset on retry

On the failure path, _failed is set to true but is never reset to false on a
subsequent successful load. This is the sticky-boolean-latch pattern identified in
AGENTS.md §4.3: if a load fails and then a revision bump triggers another _load()
that succeeds, _failed stays true because the success branch only sets _failed =
false inside the same setState that also sets _d — but if stillNewest is false for
the success branch (e.g. a race), _failed is never cleared. More critically, the
success branch already resets _failed correctly, but the failure branch sets it
without resetting _loading to false consistently — confirm _loading is always set
false on the failure path too.

lib/ui2/screens/home_screen.dart [1123-1125]

+} catch (_) {
+  if (stillNewest(#home, t)) setState(() => (_loading = false, _failed = true));
+}
 
-
Suggestion importance[1-10]: 1

__

Why: The success branch already sets _failed = false (line 1121), so a successful retry after a failure correctly clears the flag. The existing_code and improved_code are identical, meaning no actual change is proposed. The concern about _loading not being reset is also unfounded since the success branch sets it to false as well.

Possible issue
Avoid fabricating absence reason for partial measurements

The foot is only shown when both hrv and rhr are absent, but why falls back to the
sleep ring's why even when hrv or rhr is present — the fallback is evaluated
unconditionally. More critically, when hrv >= 0 but rhr < 0 (or vice versa), foot is
suppressed entirely even though the widget has a partial measurement and a reason
for the missing one. The condition should match the intent: show the reason only
when both are absent, but compute why lazily inside that branch to avoid the
unnecessary ring() call and the fabricated-reason risk when only one metric is
missing.

android/app/src/main/kotlin/wtf/openstrap/openstrap_edge/OvernightWidgetProvider.kt [72-74]

-val why = (widgetData.getString("overnight_why", "") ?: "")

+        .ifEmpty { w.ring(widgetData, "sleep").why }
+} else ""
Suggestion importance[1-10]: 7

__

Why: The suggestion correctly identifies that why is computed unconditionally even when only one metric is missing, and the foot is suppressed in that case. Moving the why computation inside the if branch avoids the unnecessary ring() call and is a cleaner, more correct pattern. The improved code accurately reflects the change.

Medium
Fix NaN standard deviation for single-element baseline

When base.length == 1, the sample standard deviation divides by zero, producing NaN.
delta.abs() <= 0.5 * NaN is false, so a single-element baseline always reports a
direction rather than Trend.steady. The comment explicitly says a zero-spread
baseline must not abstain, but a NaN spread silently breaks the threshold comparison
for any baseline of size 1. Guard with base.length < 2 to return Trend.steady (not
null — there are enough total values) when SD is undefined.

lib/ui2/grammar.dart [1127-1130]

-final sd = math.sqrt(
-    base.map((x) => (x - mb) * (x - mb)).fold<double>(0, (a, b) => a + b) /

+final sd = base.length < 2

+            (base.length - 1));
 if (delta.abs() <= 0.5 * sd) return Trend.steady;
Suggestion importance[1-10]: 6

__

Why: When base.length == 1, dividing by base.length - 1 (zero) produces NaN, causing delta.abs() <= 0.5 * NaN to always be false and incorrectly reporting a direction. The fix of using 0.0 for SD when base.length < 2 is reasonable, though the minimum baseline size (baseMin = 4) makes this edge case unlikely in practice.

Low
Re-read on notifier replacement in didChangeDependencies

When didChangeDependencies fires and the notifier has changed, _seen is updated to
the current revision value but reload() is never called. This means a screen that
was built with one AppState (e.g. after a hot-restart or a provider replacement)
will silently skip the re-read it should do when it first attaches to the new
notifier, and will only reload on the next tick — missing any data that was
already present at attachment time. After re-subscribing, call reload() if the
revision has already moved past _seen.

lib/ui2/revision.dart [49-64]

 @override
 void didChangeDependencies() {
   super.didChangeDependencies();
   if (!revisionReloads) return;
-  // No AppState above us in a golden or a widget test — such a screen just
-  // renders what it has, exactly as it did before this mixin existed.
   final AppState app;
   try {
     app = context.read<AppState>();
   } catch (_) {
     return;
   }
   if (identical(_rev, app.insightsRevision)) return;
   _rev?.removeListener(_onRevision);
   _rev = app.insightsRevision..addListener(_onRevision);
-  _seen = app.insightsRevision.value;
+  final current = app.insightsRevision.value;
+  if (current != _seen) {
+    _seen = current;
+    reload();
+  } else {
+    _seen = current;
+  }
 }
Suggestion importance[1-10]: 4

__

Why: The scenario (AppState replacement mid-lifecycle) is rare in practice since AppState is typically a root-level singleton. The _seen is initialized to -1, so on first attach the revision value will differ and reload() would be called — but the screen's own initState/didChangeDependencies already handles the first load. The edge case is real but unlikely to matter in production.

Prevent hardware-bitmap Canvas crash in icon draw

icon.draw(Canvas(bmp)) creates a new Canvas wrapping the already-returned bmp, but
ringBitmap may return a hardware-accelerated bitmap on API 26+, which cannot be
drawn into via a software Canvas — this will throw IllegalStateException: Software
rendering doesn't support hardware bitmaps at runtime on affected devices. The
bitmap must be created with Bitmap.Config.ARGB_8888 (software) to be drawable, which
ringBitmap should already guarantee, but the icon draw should reuse the same canvas
that ringBitmap used internally rather than constructing a second one over the
finished bitmap.

Suggestion importance[1-10]: 3

__

Why: The concern about hardware bitmaps is theoretically valid, but ringBitmap creates bitmaps with Bitmap.createBitmap using ARGB_8888 config (standard software-backed), so the crash scenario is unlikely in practice. Additionally, the improved_code is messy and self-contradictory (contains dead code and a comment placeholder), making it unreliable as a fix.

General
Fix mismatched arc colour when tier is absent

When tier is -1 (no data published yet), w.tierColor(-1, pal) returns pal.inkMuted,
which is the absence colour — so a recovery ring that IS measured but whose tier
hasn't been written yet will render in the muted/absent colour rather than a real
accent. The recovery ring's r.measured state should gate whether the tier colour or
the muted colour is used, consistent with how r.color(accent, pal) already works for
the other rings: if r.measured is false the tint is already overridden to
pal.inkMuted inside RingData.color, but if r.measured is true and tier == -1 the arc
will be drawn in inkMuted while the number is in pal.ink, producing a mismatched
pair.

android/app/src/main/kotlin/wtf/openstrap/openstrap_edge/OpenStrapWidgetProvider.kt [112-121]

 val tier = w.readInt(prefs, "readiness_tier", -1)
 var gap: Pair<String, String>? = null

     val accent = when (slot.key) {
-        "recovery" -> w.tierColor(tier, pal)
+        "recovery" -> if (r.measured && tier >= 0) w.tierColor(tier, pal) else pal.inkMuted
         "strain" -> pal.move
         else -> pal.sleep
     }
Suggestion importance[1-10]: 6

__

Why: The suggestion correctly identifies a real edge case: when tier == -1 but r.measured is true, tierColor returns pal.inkMuted for the arc while r.color returns pal.ink for the number, creating a visual mismatch. The improved code guards against this by checking both r.measured and tier >= 0 before applying the tier color.

Use measuredOnly filter in baseline history load

LocalDb.metricSeries without a limit is ORDER BY date ASC and returns ALL rows. The
comment in the existing code explicitly warns that metricSeries(limit: n) returns
the OLDEST n, and the trailing window is taken in Dart. However, without
measuredOnly: true here, the filter is done manually via imported.contains(date),
which is correct — but metricSeries may still return rows for keys written by
importers that are not in importedDates() if the importer wrote them without setting
the imported flag. More critically, the local_repository_impl.dart diff shows
measuredOnly: true being added to several call sites; this baseline load should use
the same parameter for consistency and to avoid relying solely on the in-memory set,
in case importedDates() misses any edge case.

lib/compute/derivation_engine.dart [1506-1519]

 static Future<_BaselineHistoryCache> load() async {
   final imported = await LocalDb.importedDates();
   Future<List<_DatedValue>> hist(String key) async {

+    final rows = await LocalDb.metricSeries(key, measuredOnly: true);
     final out = <_DatedValue>[];
     for (final row in rows) {
       final date = row['date'];
       final value = row['value'];
       if (date is! String || date.isEmpty || value is! num) continue;
       if (imported.contains(date)) continue;
       out.add((date: date, value: value.toDouble()));
     }
     return out;
   }
Suggestion importance[1-10]: 5

__

Why: The PR deliberately uses imported.contains(date) as the filter mechanism in _BaselineHistoryCache.load() rather than measuredOnly: true, because the comment explains the source column is NULL for pre-schema-43 rows and importedDates() is the correct union. Adding measuredOnly: true could be redundant or even harmful if it uses a different filter criterion, but the suggestion raises a valid defense-in-depth concern about consistency with other call sites.

Apply quiet-hours cap for all window shapes

The quiet-hours cap is only applied when quietStartMin > quietEndMin (an overnight
window that wraps midnight). A same-day quiet window (e.g. 22:00–23:00, where
quietStartMin < quietEndMin) never has the cap applied, so the check-in can be
scheduled inside it. The inQuietHours guard at the end catches this and returns
null, but the clamping to checkInEarliestMin after the skipped cap can push t back
into the quiet window, silently dropping the prompt rather than placing it before
the window. The cap should apply whenever quietEnabled is true and the computed time
would fall inside the quiet window.

lib/notify/notification_center.dart [475-490]

 static int? checkInMinute(NotificationPrefs prefs, double? bedtimeMinOfDay) {
   if (!prefs.checkInEnabled) return null;

-  if (prefs.quietEnabled && prefs.quietStartMin > prefs.quietEndMin) {
+  if (prefs.quietEnabled) {
     final cap = prefs.quietStartMin - 30;
     if (t > cap) t = cap;
   }
   if (t < checkInEarliestMin) t = checkInEarliestMin;
   if (prefs.inQuietHours(t) || t >= 24 * 60) return null;
   return t;
 }
Suggestion importance[1-10]: 4

__

Why: The suggestion identifies a real gap where the cap is only applied for overnight quiet windows (quietStartMin > quietEndMin), but the inQuietHours guard at the end already handles the case by returning null. The proposed fix could also cause unintended behavior for same-day windows where quietStartMin - 30 might be a poor cap value.

Guard against non-String values in imported dates query

_importedDatesSql UNIONs metric_series_version.date and day_result.day_id, both
aliased as date. If either column contains a non-String value (e.g. an integer rowid
stored in a legacy row), the hard cast r['date'] as String will throw at runtime and
corrupt every baseline read that calls importedDates(). Use a safe cast to avoid a
crash that silently breaks all baseline filtering.

lib/data/db.dart [6145-6147]

 return {
-  for (final r in await db.rawQuery(_importedDatesSql)) r['date'] as String,
+  for (final r in await db.rawQuery(_importedDatesSql))
+    if (r['date'] is String) r['date'] as String,
 };
Suggestion importance[1-10]: 4

__

Why: The hard cast r['date'] as String could theoretically throw if a non-String value exists, but SQLite date columns in this schema are consistently stored as strings, making this a low-probability edge case. The defensive cast is a reasonable safety measure but has limited practical impact.

Low
Bump revision after import state is fully recorded

app.bumpInsights() is called immediately after importJournalCsvFile completes, but
the journal rows may not yet be durably committed if importJournalCsvFile uses a
deferred or batched write. More importantly, bumpInsights() is called inside a try
block; if the subsequent rejected.addAll or sources.add throws, the bump has already
fired but the import state may be inconsistent. This is a minor ordering concern,
but the bump should be placed after all state from this import leg is recorded, to
avoid a revision tick that causes screens to re-read before the import's own
metadata (rejected list, sources) is updated in the surrounding accumulator.

lib/ui2/onboarding/welcome.dart [384-393]

 try {
   final r = await importJournalCsvFile(p);
   journalRows += r.imported;
-  // This one writes straight to the journal store rather than through
-  // AppState, so it has to raise the signal itself — every other importer
-  // here does it from its AppState method.
-  if (r.imported > 0) app.bumpInsights();
   rejected.addAll(r.rejected.map((x) => x.toString()));
   if (!sources.contains('Journal CSV')) sources.add('Journal CSV');
+  // Bump after all local state is recorded so screens re-read a
+  // consistent picture.
+  if (r.imported > 0) app.bumpInsights();
 } on JournalCsvFormatException {
Suggestion importance[1-10]: 3

__

Why: The concern about rejected.addAll or sources.add throwing is very unlikely since these are simple in-memory list operations. The ordering issue is minor and the bumpInsights() call triggering a re-read before local accumulators are updated doesn't affect the database state that screens actually read.

Inline comments:
In `@lib/app.dart`:
- Around line 367-374: Update WellnessScreen to accept an initial sub-tab
selection, and pass the Medication tab index when handling kRouteMeds. Ensure
the existing route resolves to the Wellness shell without pushing a duplicate
screen, while other Wellness routes retain their current default tab behavior.

In `@lib/data/db.dart`:
- Around line 6095-6149: Update _importedDatesSql so its day_result branch
applies _servedDayJoin before evaluating the payload_json imported marker,
ensuring superseded imported rows do not exclude dates when a newer served
band-derived row exists. Keep the metric_series_version branch and existing null
guards unchanged.
- Around line 6918-6934: Update metricSeries and the surrounding callers to
derive imported dates from each day_result’s served version, compute that date
set once per operation, and filter all requested metric series in Dart instead
of embedding _importedDatesSql in every query. Reuse the computed set across
loadRoughNight, getJournalInsights, and rescoreRecentSessions, while preserving
measuredOnly behavior and allowing a newer measured served row to retain its
date.

In `@lib/notify/notification_center.dart`:
- Around line 242-245: In lib/notify/notification_center.dart lines 242-245,
update the medication-slot cancellation condition to distinguish a loaded empty
schedule from an unavailable schedule: cancel when medication notifications are
disabled or the schedule was successfully loaded, including when medDefs is
empty. In lib/state/app_state.dart lines 2292-2306, change the database-failure
path to return the existing unavailable schedule state rather than a loaded
state with defs: [].

In `@lib/state/app_state.dart`:
- Around line 2275-2289: Update _checkInDoneToday to return Future<bool?>,
keeping successful journal checks as true or false and returning null when the
journal read fails. Preserve the existing
NotificationCenter.scheduleStandingReminders behavior that treats null as
unknown and retains the current check-in slot.

In `@lib/ui2/grammar.dart`:
- Around line 1227-1258: Update the Pressable semanticLabel to announce status
when it is non-null, matching the trailing widget that replaces the trend arrow;
otherwise retain _trendWord(trend) for rows without status.
- Around line 1161-1169: Update stale MetricRow.spark references to use the
current series field or the established default in the MetricRow-related code
and chart test, preserving existing behavior.

In `@lib/ui2/profile/devices.dart`:
- Around line 273-294: The no-band StatusCard message should reflect actual
phone reporting status rather than merely a nonempty sources list. In the
hasBand guard, use the phone-only message and spacing condition only when tier
equals SourceTier.phone and connected is true; otherwise retain the “Nothing is
measuring yet” message.

In `@lib/ui2/profile/gallery.dart`:
- Around line 64-69: Add a deterministic descending-series fixture alongside
_rising, _flat, and _tooShort, then assign it to one MetricRow in the gallery so
Trend.falling is produced and the arrowDownRight branch is exercised.

In `@lib/ui2/README.md`:
- Around line 199-205: Update the README description of trendOf’s baseline in
the trailing-slot documentation to state that it uses up to fourteen preceding
values, with at least four required, while preserving the existing explanation
of direction and insufficient-data behavior.

In `@lib/ui2/revision.dart`:
- Around line 70-76: Update lib/ui2/revision.dart lines 70-76 in _onRevision to
serialize reload() calls, tracking the in-flight operation and coalescing
revisions until it completes. Add load-generation checks before setState in
lib/ui2/screens/cycle_screen.dart lines 216-222,
lib/ui2/screens/home_screen.dart lines 1100-1109,
lib/ui2/screens/nutrition_screen.dart lines 63-68, and
lib/ui2/screens/wellness_screen.dart lines 91-95 so stale results cannot
overwrite newer state.

In `@lib/ui2/screens/health_screen.dart`:
- Around line 450-470: Update reload() and the _load, _loadVitals, _loadLabs,
and _loadExplore loaders to track a separate request generation for each
resource, incrementing it whenever a load starts and capturing that generation
before awaiting. Only commit the awaited result when its captured generation is
still current, preventing older reads from overwriting newer revision-refresh
data.

In `@lib/widget/widget_service.dart`:
- Around line 231-242: Clamp the computed sleep fraction in the sleep _Ring
construction to the inclusive 0–1 range before assigning it to frac, while
preserving the existing null behavior when need is empty or non-positive.
- Around line 457-463: Update the _Ring construction in the
baselineCountsFromNote calibration branch so the clamped counts.have /
counts.need fraction is converted to double with toDouble() before passing it to
frac, preserving the existing clamp range and display behavior.

sleeping longer than your need is a fraction above 1 and the native
readers take that straight to the arc. clamped in _Ring rather than at
the call site so the next ring can't reintroduce it. the number still
says 8h 10m of 7h 30m — only the arc is bounded.
two durable writes close together start two reloads, they finish in
whatever order the scheduler resumes them, and when the older one wins
its setState puts pre-import data back on screen. on a tab the
IndexedStack keeps alive that stands until the app is relaunched, which
is the exact thing RevisionReload was written to end.

guard in the mixin, one token per resource, so the screens get two lines
each instead of four hand-rolled counters. not a queue — the newest data
shouldn't wait behind a read it already superseded, and a loader that
hangs shouldn't block every later one. overlapping reads are fine, only
overlapping commits aren't.

workout is already safe, it hands the future to a FutureBuilder.
wellness gets the same guard in the next commit.
it landed on wellness and left you to find the tab. a constructor arg
can't fix it — the shell keeps wellness alive in its IndexedStack, so a
tap while wellness is already up rebuilds nothing to carry the index. so
the shell asks and the screen listens, and the request is cleared a
frame later rather than consumed on read: on the re-key path the
outgoing state's listener fires before the incoming state exists.

still pushes no screen, that part was always right. the tab list moves
onto the widget so the index the deep link hands over can be checked
against it.

also carries wellness's share of the stale-read guard.
the imported-days mask tested every day_result row, and versions are
siblings under that primary key — so an imported day the band later
re-derived kept its old imported row beside the new measured one and
stayed masked out of the baselines it's now entitled to be in. served
version only, same join every other reader uses. the series-version half
is keyed on date and replaced by the last writer, it's fine as is.

while in there: measuredOnly inlines that mask as a subquery whose
expensive half is a LIKE over whole day bundles. rough night and the
journal insights each read four series, so each was doing four full
passes over your history for one answer that can't change between them.
take the set once, filter in dart — which is what the doc comment on
importedDates already said to do.
both arrived as an empty list and the scheduler picked preserve for
both, so deleting your last medication left its reminders armed with
nothing to ever cancel them. null now means unread — the switch is off,
the read threw, or the notifications screen is re-asserting after an
unrelated toggle — and an empty list means you have none, which cancels.

same class in the check-in: a journal read that threw returned false,
and the scheduler reads false as "today is known to be unanswered", so
it could ask how your day was after you'd already told it. null, which
it already has a branch for.
the pairing card said "the phone counts steps" whenever the toggle was
on. the phone row is listed on the toggle but only counts as connected
once steps are actually banked (ios reports auth success on a denied
read), so the card has to test the same thing the row does.

a metric row showing ON TRACK announced "trending up" — status replaces
the arrow, so it has to replace the word too.

two stale [MetricRow.spark] refs, the field is series. the readme said
trendOf compares against the fourteen before them, it's up to fourteen
and four is enough. and the gallery had no falling fixture, so the down
arrow was the one glyph in that slot nobody could look at.

@abdulsaheel I completed the follow-up review against #258.

I found no new actionable issue in the updated code.

The fixes cover the medication deep link, imported-date masking, reminder availability states, stale-read protection, and sleep-ring bounds.

The clamp concern is withdrawn. The rrMs.length.clamp(0, 4) assignment is valid Dart and must not be reported as a Uint8List integer-type error. The current _Ring clamp is also valid because its input has static type double.

The focused test files were unavailable in this sandbox checkout. I could not inspect them here.

571-576: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Resolve medication slots as local calendar times.

localDayStartSec(s.date) + s.slotMin * 60 treats the local offset from midnight as elapsed time. On a DST transition day, it schedules doses after the offset change one hour early or late.

Construct the local DateTime from the day label, hour, and minute. Convert that wall-clock time to an absolute instant only after construction.

Proposed fix
 static DateTime? medSlotInstant(MedSlot s) {
-  final start = localDayStartSec(s.date);
-  if (start == null) return null;
-  return DateTime.fromMillisecondsSinceEpoch((start + s.slotMin * 60) * 1000);
+  final parts = s.date.split('-');
+  if (parts.length != 3) return null;
+  final year = int.tryParse(parts[0]);
+  final month = int.tryParse(parts[1]);
+  final day = int.tryParse(parts[2]);
+  if (year == null || month == null || day == null) return null;
+  return DateTime(year, month, day, s.slotMin ~/ 60, s.slotMin % 60);

key on each revision, including Vitals, Labs, and Explore when their cached
values are null or reads are in flight. Preserve lazy loading by only starting
fetches when appropriate, but ensure stillNewest() rejects all pre-revision
reads before they can commit.

Outside diff comments:
In `@lib/notify/notification_center.dart`:
- Around line 571-576: Update medSlotInstant to construct the medication time as
a local DateTime from s.date and the slot’s hour/minute, then use that
wall-clock value as the absolute instant; do not derive it by adding slotMin to
localDayStartSec, since DST days are not always 86400 seconds long.
- Around line 215-295: Expose a single AppState scheduling entry point that
delegates standing-reminder re-arming to NotificationCenter. Invoke it after
every successful medication schedule, dose-state, rating, and journal compose
write, including raw decode and relevant export/session-triggered paths, so
stale medication and completed check-in notifications are reconciled. Keep
NotificationCenter as the scheduling owner and preserve the existing
_ensureRemindersScheduled startup, resume, and preference-change behavior.

Invalidate in-flight sub-tab reads during revision reloads.

stillNewest rejects an old result only after a newer token is issued. reload() starts Vitals, Labs, and Explore refreshes only when their cached value is non-null. If a sub-tab is already loading, its cache remains null, so the revision event does not issue a newer token for that key. The older read can then pass stillNewest and commit stale data after the revision.

Ensure that reload() invalidates every sub-tab key on each revision, including null-cache and in-flight states. Preserve lazy loading if needed, but do not allow a pre-revision read to commit after the revision.
