Home: say why a ring needs attention, right on the ring card - #681
Home shows three rings, but when one of them is off, the card doesn't say why. The only explanation was a "Why?" line under the card listing recovery driver names, with nothing for sleep or strain. This PR puts a short answer on the card itself for the rings that need it, lets the rings show how far past their target you went, and breaks the sleep ring into your sleep stages.
This builds on #679 (scroll-first scrubbing and the reading panel), so that one should land first. Until it does, this PR's diff also contains #679's commits; this compare view shows only this PR's own changes.
What changes
The ring card says why. Under the rings, the card shows at most two rows, for the rings that most need attention:
"Recovery is low", with the score.
"Sleep is short of need", with how long you slept, how far under your need, and the need itself.
"Strain is above target", with today's strain and today's target range.
A ring with no value says so ("No reason recorded.") instead of a blank.
When recovery has just been recalculated, the update note takes a row. Each row opens the same detail screen as its ring. The "Why?" footer is gone; tapping the recovery ring still opens Readiness, which has the full driver breakdown with each driver's weight.
Rings go past 100%. Past its target, a ring keeps going as a spiral, one lap inside the last with a thin separator, so 120% of your sleep need looks different from 100%. Under 100% nothing changes.
The sleep ring shows its sleep stages. When last night was scored with stages (the stored deep, REM and light minutes), the sleep ring is drawn as Deep, REM and Light arcs in the hypnogram's colours, in that order, scaled so together they sweep exactly the share of your need you slept. Time awake in bed follows as a fourth arc, only in the part of the ring that is still open, so it never pushes the ring past what you actually slept. A night without stage data keeps the plain single-colour ring. The caption reads "94% of 8h 00m", with "(default)" while your need is still the default.
Plainer labels. 11 existing Home strings are reworded (for example "Updating your trends" for the rollup rebuild card) and 25 new ones added, in all 8 languages. Thai is translated fresh. Chart axes say "1 day ago", not "1 days ago", and the "days behind" count uses the app clock, so it is testable.
Tradeoffs worth knowing.
The card shows at most two rows, so on a day where all three rings need attention, the third ring's row waits until one of the others clears. Its ring is still tappable.
The recovery row shows the score, not the drivers. The recovery ring is a composite and has no per-driver evidence of its own; naming drivers from a different calculation could blame the wrong thing.
Ring itself now spirals past 100%, so the steps ring on metric detail, the live screen and Home's steps ring do too.

How I tested it
New tests cover the row ranking and the two-row cap, each why row's text in every locale, the plain recovery score (including when an older rollup or a different calculation disagrees), the spiral geometry and its pixels past 100%, 200% and at the seam, the stage arcs, the card at 1.0, 1.5 and 2.0 text with no row overflowing, Thai layout with a verified Thai font, plural forms for every locale, and one decode per day switch through the real repository.
Existing tests changed: four, each because it asserted text or layout this PR changes.
I've run the fork version of this on my daily build, and I'm confident it works.
flutter analyze: clean.
Full suite (flutter test, 2 workers) on eb3190a2: 7,262 passed, 29 skipped, 15 failed. None of the remaining failures come from this PR:
10 pass on my machine on this branch: the time-zone tests that can't run on the cloud machine I used (day_window_dst_test, luteal_flags_dst_test, band_step_spans_local_hour_test), and three that flaked under 2-worker load (device_coverage_test ×2, app_state_sync_open_session_test).
4 are settings_report_l10n_test (es, fr, hi, zh), which main a9b765a7 fails on its own.
1 was a test pinning the old rebuild-card wording; it is updated in 6aca1a6d.
Not in this PR
A "you're on track for N sleep cycles tonight" estimate. It needs to know when your day actually ends, which I want to tie to your own sleep–wake cycle rather than a clock time, so it's coming with that work.
The fork's shared header, provenance rows and the day review list.
… annotations
Inert stubs only (chart_annotations.dart, ChartFrame.annotations/annotationCursor,
MetricDetail.annotationLoader/journalToggleKey) so the suites compile.
187 tests, 165 failing on assertions.
Icon and dashed-line marks, shaded ranges and +n clusters laid out by a
pure engine in chart_annotations.dart. ChartFrame draws the lane above the
plot in its own RepaintBoundary; with no annotations it renders as before.
…ions
Scrubber states increase/decrease values whenever it has a value, and Flutter
rejects an empty neighbour; real callers always describe the position.
… the page
The Scrubber was a bare Listener that moved the marker on every pointer-down
and move, so a page scroll that began on a chart also dragged the marker.
It now joins the gesture arena: a tap selects on release, a drag scrubs only
when it is horizontal-dominant (more than 1.5x the vertical) past the
device touch slop, and a long press selects and then follows any axis.
…readiness charts
An inset panel under the chart reads LATEST at rest and SELECTED while a
finger is on it, so the chart no longer changes height under the thumb. A gap
reads a dash, never a neighbour. Metric detail adds 7-day avg and vs avg and
an Open <day> action; the sleep charts read the stage from the timestamped
boundaries and each signal within 15 minutes; readiness gets the same panel.
…ric detail
Version changes become an icon with a dashed line in the annotation lane,
replacing the dotted marks. A chip, off by default and reading nothing until
turned on, adds the window's workouts, timed meals and timed journal fields.
…e selected
The panel excluded every cell from semantics and the sleep sliders only said
the time and stage, so heart rate, HRV, breathing and temperature were never
spoken, and the resting LATEST reading was silent everywhere.
One owner at a time: at rest the panel speaks 'LATEST . day, label value, ...'
as a single node; while a day or instant is selected the slider speaks the
whole reading (sleep now adds every signal, a missing one as 'No record') and
the panel stays silent.
The lane excluded its semantics and offered one comma list of labels, so a
screen reader could neither focus an icon nor step a cluster, and never heard
what kind of thing each mark was.
Each icon is a button labelled '<kind>, <label>'; the +n button steps the
cluster and names the members the icon does not show; marks too crowded for
an icon are still spoken. Kind words reuse existing strings; Moment and
Symptom are new in all eight locales.
…read tests
SlotScrub labelled its days against the clock at each touch, so a chart left
open across midnight shifted every label without shifting the data. The
caller now passes the calendar day the series was built for (Workout reuses
trimpEnd; HRV and the month grid take the day they built their window on).
The failed-read test now makes the loader throw. The local-day tests run in
America/New_York with literal timestamps across both DST transitions.
Drop stepAnnotationFocus, which nothing called, and say plainly that the
no-repaint test is a component check, not a claim about the sleep plots.
ChartPanel takes an optional note line (and reserveNote to keep its height on
multi-device windows). Metric detail fills it with the day's contributors under
the same gate and rules as the slider reading. The slider owns it while
scrubbed; at rest it ends the resting reading, so it is spoken once.
… tap target, stale journal read)
- scrubbed onto a no-value day, the panel names no device, as the slider
- a mark whose label is its kind name is spoken once
- SlotScrub: optional dayWord (HRV says "Last night"); no day named when no
slot has a value
- annotation icon hit box ends at the plot seam, so a drag under an icon scrubs
- drop a journal read that started before a reload
- fix the 7-day average arb description and two doc comments
Metric detail no longer draws an annotation lane or the Journal marks
chip; algorithm-version changes are the plain dotted xMarks lines again,
with upstream's footnote wording in all locales. The annotation engine
stays for single-day graphs.
The annotation lane, its icons and sources, and their tests are saved on
pr/edge-chart-annotations. This PR keeps the scroll-first scrubber and the
chart panel.
The panel's value line ends in the same chevron the old pop-in row had when
the shown day can be opened, and nothing on a day that cannot. A panel that
offers to open keeps the chevron's width on a gap day, so scrubbing onto one
never changes its height. The chevron is not spoken; the panel already says
Open <day>.
A missing stat is spoken as "No record". A panel with no cells and a
SlotScrub with no series no longer throw. Readiness dates its history from
the day the series was built, and a missing day keeps the swatch width (the
sleep stage cell too). A device's gaps between epochs read as not measured.
Both sleep charts share one selected instant instead of one fraction, and a
night with no staging no longer says "not measured".
Rings past 100% draw as an eased spiral with one separator per lap; the sleep ring model groups a scored night into stage arcs against the person's need (or a labelled 8 h default) and estimates tonight before sleep. The pixel probes now fail against a flat ring.
The ring card ends in up to two inset rows: why the most pressing rings are low (recovery under 37, sleep under 85% of need, strain above target), the recovery update note, then an absent ring's reason. The sleep ring shows a scored night as stage arcs against its target ('92% of 8h 00m (default)') and, before sleep, an estimate that follows the clock each minute. Eleven Home strings lose their jargon, the illness texts no longer print a z multiple, and 25 new keys are added in all eight locales. axisDay says '1 day ago' and daysBehind counts on the injectable clock.
The 'on track for N cycles' estimate and everything that only served it
move out of this PR: the alarm/learned-wake/learned-onset/coach-bedtime
selection and night boundary in sleep_ring_model, the minute tick, the
HomeData estimate inputs and sleepWindows read, the estimate strings in
all eight locales, and their tests. The no-sleep ring uses upstream's
homeSleepGapFallback again.
…arget per locale, trim dead code and keys
Past-day need comes from the night's own need_min (same source and staleness gate as getInsights); drop the second read and sleepCoachOf. The strain target range uses displayFixed. Remove unused homeWhyLabel/homeSleepNoTarget/homeOfSpan, dead caption/LayoutBuilder code and stale comments, the test-only Ring/StageRing.pieces getters and the duplicate gradientAt. Tests call SpiralGeometry directly; the round2/round3 spiral tests merge into ui2_spiral_ring_test.dart; the glassbox absence tests become one load assertion.
The PR adds reusable chart panels and slot scrubbing to multiple charts. It updates sleep-stage chart interactions and Home ring calculations and rendering. It also revises chart and Home text in eight localization catalogs.

The title "Home: say why a ring needs attention, right on the ring card" matches the main change in the changeset. The PR adds explanation rows to the Home ring card for recovery, sleep, and strain rings, and the raw summary of home_screen.dart confirms it. The title is specific and concise, and it names the Home screen and the ring card. It does not cover every detail, such as the spiral ring rendering, localization, or chart panel work, but the task does not require that.

Inline comments:
Review comments at @lib/compute/vendor_sleep.dart:
- Around line 60-61: Update the epoch-processing logic around epochs and the
unobserved-boundary insertion so overlapping epochs are resolved using the
defined stage precedence before gaps are calculated. Add an unobserved boundary
only when no resolved epoch covers that time, including when a shorter epoch
ends inside a longer one.
Review comments at @lib/ui2/grammar.dart:
- Around line 399-413: Update the `Semantics` handling around `_caption` and
`_reading` so the selected gallery `ChartPanel` without a `Scrubber` has a
semantic owner that exposes its caption and missing heart-rate reading to screen
readers. Preserve the existing semantics behavior for other panels.
- Around line 499-508: Update the caption-height cache key used by the
`tallest(timeSpan)` lookup to include the `timeSpan` strings with value-based
equality, rather than relying only on `Object.hashAll(timeSpan)` and
`timeSpan.length`; preserve the other key components.
Review comments at @lib/ui2/screens/home_screen.dart:
- Around line 1205-1208: Load the retained strain target for the selected day
into HomeData.strainTarget when it belongs to that day, using date-specific
storage for older targets because the cross-day artifact retains only one
target. Use past-day wording for a selected past day with a matching target, and
preserve the above-target explanation when a row is available.
- Around line 1796-1799: Update the historical-night need handling around
`metricOf(sleep['need_min'])` so the caption and shortfall explanation do not
imply that the current sleep-coach need is historical. Use a date-specific need
when available; otherwise clearly label the comparison as based on the current
need, preserving the existing absent-need behavior.
- Around line 1049-1055: Update the sleep-shortfall calculation in the Home
sleep explanation to compare asleep minutes with the completed night’s target,
not tonight’s need; if that target is unavailable, withhold the shortfall alert.
Keep the existing detail formatting and fallback behavior for valid comparison
values.
Review comments at @lib/ui2/screens/metric_detail.dart:
- Around line 1647-1649: Update the `note` assignment so a selected gap reflects
the slider’s distinction between a device recording and no recording, rather
than always hiding `who` when `_pick` is set and `v` is null. Keep the status
unknown when the recording device cannot be named.
Review comments at @lib/ui2/screens/month_grid.dart:
- Around line 274-276: Increase the scrubber’s touch target around `CustomPaint`
in the month strip while keeping the painted strip at 22 logical pixels high.
Ensure touches in the added area still reach the existing day-selection scrub
behavior.
Review comments at @lib/ui2/screens/sleep_detail.dart:
- Around line 1603-1606: Update recorded in the sleep detail signal-cell flow to
require at least one valid reading within the displayed chart’s night window
before adding a cell; apply the same window check to scrub readings and use the
selected device’s window where applicable.
Review comments at @lib/ui2/screens/slot_scrub.dart:
- Line 121: Update SlotScrub’s drag-completion handling to clear the historical
slot selection and restore the latest reading after the user lifts their finger.
Apply the same completion behavior in readiness and metric detail, while
preserving the metric panel’s day-opening action.
Review comments at @lib/ui2/sleep_ring_model.dart:
- Around line 57-59: Update the learnedNeed check before calculating target so
values that round to zero use kDefaultSleepTargetMin; also reject non-finite
needs to prevent an invalid target from reaching _slept. Preserve the existing
learned-need behavior for valid values that round to a positive target.
- Around line 85-89: Adjust the awake arc allocation around asleepFrac and
SleepArcKind.awake so the awake portion is represented within the existing sleep
sweep rather than added to its progress. Keep the combined sweep extent at
asleepFrac, so the ring reflects the 75% caption in the stated scenario.

Different timeSpan lists can have the same hash and length but need different caption heights. The second chart can then reflow while scrubbing. Include the strings in the cache key using value equality.

If tonight’s need is higher than the completed night’s target, Home can report a false sleep shortfall. For example, eight hours of sleep against tonight’s ten-hour need produces a two-hour shortfall alert. Use the completed night’s target, or withhold the alert when it is unavailable.

When the saved cross-day target belongs to the selected past day, load it into HomeData.strainTarget and use past-day wording. Otherwise, the card omits the above-target explanation even when a row is available. Older targets need date-specific storage because the cross-day artifact retains only one target.

Home shows three rings, but when one of them is off, the card doesn't say why. The only explanation was a "Why?" line under the card listing recovery driver names, with nothing for sleep or strain. This PR puts a short answer on the card itself for the rings that need it, lets the rings show how far past their target you went, and breaks the sleep ring into your sleep stages.
This builds on #679 (scroll-first scrubbing and the reading panel), so that one should land first. Until it does, this PR's diff also contains #679's commits; this compare view shows only this PR's own changes.
What changes
The ring card says why. Under the rings, the card shows at most two rows, for the rings that most need attention:
When recovery has just been recalculated, the update note takes a row. Each row opens the same detail screen as its ring. The "Why?" footer is gone; tapping the recovery ring still opens Readiness, which has the full driver breakdown with each driver's weight.
Rings go past 100%. Past its target, a ring keeps going as a spiral, one lap inside the last with a thin separator, so 120% of your sleep need looks different from 100%. Under 100% nothing changes.
The sleep ring shows its sleep stages. When last night was scored with stages (the stored deep, REM and light minutes), the sleep ring is drawn as Deep, REM and Light arcs in the hypnogram's colours, in that order, scaled so together they sweep exactly the share of your need you slept. Time awake in bed follows as a fourth arc, only in the part of the ring that is still open, so it never pushes the ring past what you actually slept. A night without stage data keeps the plain single-colour ring. The caption reads "94% of 8h 00m", with "(default)" while your need is still the default.
Plainer labels. 11 existing Home strings are reworded (for example "Updating your trends" for the rollup rebuild card) and 25 new ones added, in all 8 languages. Thai is translated fresh. Chart axes say "1 day ago", not "1 days ago", and the "days behind" count uses the app clock, so it is testable.
Tradeoffs worth knowing.
Ringitself now spirals past 100%, so the steps ring on metric detail, the live screen and Home's steps ring do too.Screenshots
