The centred score number painted off the band token (success/warning/
destructive), which cleared only ~1.5:1 against the dark wellness card
and read as illegible. Switch the number to the foreground colour so it
is legible on both the dark and the light card. The band semantic stays
carried by the ring arc fill, the data-band attribute, and the
aria-label, so the colour change costs no information.

Reorder the Insights overview top → bottom to Hero + Coach, Wellnesswerte,
Vitalwerte, Trends, period retrospective, then today's signals — the
wellness-score strip and vitals grid already render in that sequence inside
the vitals dashboard, so the change is the surrounding section order plus
moving the signal cards below the retrospective.
Make the steps reference value in the daily briefing tappable: it was the one
key finding with no destination, so it now routes to the generic readings view
for its measurement type like every other metric drills in.
Paint the health-score headline number through the semantic success / warning /
destructive tokens instead of the raw dracula primitives, which carry no
light-mode override and read illegibly on the Alucard light theme.
Widen the wellness-score strip so the tiles always fill the row: the fixed
five-column desktop track left an empty cell on the common four-score case and
read as a missing tile.
Drop the duplicate footer "prepare assessments" control — the tab-strip
regenerate button is the single affordance — and remove the now-dead warm hook
and its strings.
Trim the coach suggested prompts to the two that read as a clear next step
(ask the doctor, is the medication working) and remove the three speculative
data-specific openers, across all six locales.

Settings → Integrations fired five status round-trips on every mount —
the consolidated /api/integrations/status alongside the four per-provider
/api/<provider>/status queries. Extend the consolidated endpoint to carry
every field the four cards render (Withings activity scope, WHOOP/Fitbit
backfill state, moodLog webhook secret + entry count) and drive all four
cards off the single envelope. The legacy per-provider routes stay for the
iOS/test callers; the web cards no longer hit them.
Mood-insights cache was a plain 60 s TTL that was hard-evicted on every
mood write, so an active logger re-paid the multi-second cold compute on
every entry. Add stale-while-revalidate to ServerCache (wrapSwr / cachedSwr
+ a markStaleByPrefix that collapses the fresh TTL without dropping the
value), give the moodInsights bucket a 10-minute stale window, route the
read through cachedSwr, and switch the mood-write invalidation from a hard
evict to a mark-stale so the prior aggregate serves immediately while a
single background recompute warms a fresh one.
Defer the eager Recharts on the mood-insights surface. The trajectory
forecast card pulled Recharts into the initial chunk of every
trajectory-eligible metric page though the main chart is already deferred;
split its fan band into trajectory-fan.tsx behind next/dynamic. The three
below-fold mood mini-charts (distribution / weekday / time-of-day) were
static imports under an already-dynamic hero line chart; defer them with
next/dynamic. Each loader paints a skeleton sized to the chart's own band
so the chunk arrives without a layout shift; the charts stay Recharts and
visually identical.
(cherry picked from commit 2b627893ab6b4d7bc457fc18e6e5585b048190e1)
Move the time-range pills + period-over-period delta out of the slot between
the stat strip and the chart and render them as a clean row below the chart on
every metric sub-page (the HealthKit scaffold plus weight, BMI, pulse, blood
pressure, sleep). The control owns its own persisted range pref and delta read,
and the chart owns its window via its in-card range tabs, so the relocation is
a pure DOM reorder that leaves the chart range untouched.
Right-align the last-updated timestamp on the period narrative ("Zeitraum im
Überblick") and the daily-briefing footer so the "updated" line matches the
status cards, which already route through the right-aligned footer.
Tighten the sleep average and hypnogram cards — drop the default card gap and
the headline card's extra padding that left tall empty bands — and give the
hypnogram clock-aligned X-axis ticks (whole hours on a 1–3 h step picked from
the night's span) so the time axis reads 23:00 / 01:00 / 03:00 / 05:00 instead
of raw bedtime/wake stamps.
Add a compact density to the short-horizon projection card for the metric
sub-pages: it sheds the min-height floor, shortens the chart, and surfaces how
many more days of tracking are needed before a projection can appear, drawn
from the coverage envelope. The Insights overview keeps the roomier default
geometry for grid symmetry.
The wellness-score ring tiles passed the metric title into the ScoreRing
as an in-SVG centred <tspan>. A long localised title (Schlaf-Score,
Bereitschaft) was wider than the small ring's clear centre, and because
the text is SVG-centred inside the recharts overflow:hidden svg the leading
glyph was clipped (the missing leading "S" on Schlaf-Score). Render the
title as an HTML caption below the ring instead, where it wraps within the
tile and never truncates; the ring keeps just the number centred. The
in-SVG label slot stays for the anatomy detail view, which only ever passes
the short "/100" string.
Add a short-horizon OLS projection over the DAY-native per-day mean
series, extending the existing trendSlope. The fit, residual standard
error and prediction interval are computed at DAY granularity only — the
rollup invariant forbids composing a slope/sd from WEEK/MONTH buckets.
The projection is gated on fit quality (R squared), in-window history and
staleness: below any floor the engine returns insufficient rather than a
weak line, so noise is never extrapolated. The prediction-interval band
widens with the horizon distance from the data centre, so the fan
visibly communicates uncertainty.
Register TRAJECTORY in the derived registry and dispatch (additive,
iOS-forward-compatible; the capabilities endpoint and drift-guard pick it
up automatically). Surface it on the weight detail page as a forecast
band beneath the chart, labelled a projection with the cited method and
a conditional, range-only headline — never a prediction or a dated
event. i18n across all six locales.
Carry the per-day STRAIN anchor (personal vs population) from the
strain_trimp_cache row through to the STRAIN WellnessScoreValue read, and
pick the framing line by it on the score-anatomy surface: relative to your
own typical effort once anchored personally, a general reference during
cold start. The method copy was describing both regimes generically and
could not tell the user which one produced this score. Additive read field
— iOS non-breaking.
The estimated 6-minute-walk band + the three any-user HealthKit baseline
bands (wrist temperature, stair ascent/descent speed) were registered,
provenance-mapped and engine-tested but rendered on no surface. Add a
"Mobility & body" section to the vitals dashboard: the 6MWT passthrough
re-frame (distance + trend always, percent-of-predicted framing only with
the Enright demographics) and a shared baseline-band tile for the three bands.
Every tile is data-availability-gated like the existing ones — absent with no
readings, CoverageMeter while provisional, value + framing + provenance when
ready — and the section heading hides when none resolve. All four tokens ride
the single batched derived request. Derive the sparkline gradient id via
useId() to avoid duplicate-label collisions.
The Derived<T> tile (SparklineDeltaTile) renders a trailing series, but the
engines never filled it, so the inline sparkline was always empty. Each engine
now carries a capped trailing series sourced from the rows it already reads:
- baseline-band metrics (incl. wrist-temperature / stair ascent+descent) ship
the per-day mean series the band is built from;
- HRV balance reuses the day-mean read it already does for the recent average;
- the wellness scores (recovery / stress / strain) ship their window scores;
- the six-minute-walk band ships its reading series;
- BMI reads a bounded recent-weight set and derives a BMI series at the fixed
profile height.
All series cap at the last 30 points. The vitals dashboard wires the series
into the baseline, HRV and BMI tiles; the tile already renders >= 2 points and
collapses the sparkline row otherwise.
Register four new derived metrics for the additive HealthKit signals:
- WRIST_TEMPERATURE_BASELINE, STAIR_ASCENT_SPEED_BASELINE,
STAIR_DESCENT_SPEED_BASELINE — any-user-baseline personal bands reusing
the type-generic median +/- k*MAD engine via a new BASELINE_CAPABLE_TYPES
allowlist. Wrist temperature is a personal-deviation band only (no illness
or cycle inference); stair speeds are personal trend bands (no population
cutoff, geometry-confounded).
- SIX_MINUTE_WALK_BAND — passthrough re-frame placing the device-estimated
distance against the Enright & Sherrill 1998 predicted 6MWD (ATS 2002
test standard), as percent-of-predicted with a green/yellow/red band;
band null when age/height/weight/sex are incomplete.
Fall count and the breathing-disturbance index stay trend-only by design,
documented in the registry: fall count is a zero-inflated discrete safety
event, the breathing index is a regulated screening signal where a derived
band would imply a diagnosis.
Note wrist temperature as a deferred correlation outcome channel held
pending a privacy review (cycle-phase inference risk), mirroring the
medication-compliance omission note.
Add provenance + standards entries, method/caveat copy across all six
locales, and tests for the engine routing, the Enright equation, and the
percent-of-predicted band.
Promote the COINCIDENT_DEVIATION flag from a fire-only tile buried in the
below-the-fold vitals grid to an always-mounted headline card at the top of
the Insights overview. The card renders four calm states off the single
existing derived payload — building-baselines, all-clear, watch, fired — with
no new engine math, route, or schema change.
Keep it calm and clinically safe: at most an amber band, never red, no score,
no chart, no push. Soften a fired flag to the watch tone when the backing
history is thin. The fired/watch states carry the load-bearing "possible
factors, never a cause / not a diagnosis" framing and reuse ProvenanceExplainer
+ CoverageMeter + the band tokens verbatim.
Remove the now-redundant tile, its batch token, and the hasRenderableVital
branch from the vitals grid so the signal is not shown twice.
Render a skeleton row matching the resolved tile height while the derived
batch loads so the grid reserves its final footprint with no layout shift.
Hide the section heading until there is content (or a skeleton placeholder)
under it, removing the stranded-heading layout shift on empty data. Surface
an inline error message plus a Retry that refetches the shared batch query
when the batch fails, instead of the whole surface silently vanishing. Mark
the tiles container aria-busy while loading and aria-live polite, matching
the insights a11y pattern.
Only Sleep and Readiness reached a provenance surface; the other nine
shipped a number with the cited standard buried in a code comment. Give
every derived metric a path to its inputs + method + cited standard:
- Recovery, Stress and Strain get a ScoreAnatomyView detail page and a
tappable ring (they were read-only dead-ends). Stress surfaces its
'HRV-derived proxy, NOT an EDA/galvanic measurement' caveat; Strain
cites the TRIMP load model; Recovery the HRV-guided recovery literature.
- The vitals tiles (baseline, HRV balance, BMI, fitness age, vascular age)
gain an info explainer affordance carrying the method + standard, since
they render as tiles with no detail page.
- The coincident-deviation flag gains a dashboard tile (shown only when it
fired) with the same explainer (median ± k·MAD basis).
- A single standards map (src/components/insights/derived/standards.ts)
pins each metric's method copy key, standard name and a real linkable URL
(DOI / WHO / Wikipedia) so the citation a metric exposes stays one source.
Add the per-metric method/caveat/description copy across all six locales.
Map storage units to display symbols so a baseline tile reads '36.6 °C',
not '36.6 celsius'. Show the band word under the strip rings so a value
reads 'low 62', not a bare reddish 62. Drop the empty dashed sparkline
placeholder when no trailing series exists rather than reserving dead
space, and give the tile a series + provenance slot for when one does.
The Insights cold mount fired 14+ independent GET /api/insights/derived
requests — Readiness, Sleep and the vitals baselines are compute-on-visit,
and all of them share one Prisma pool. That is the pool-starvation class
that surfaces as the app hanging then recovering.
Add GET /api/insights/derived/batch?metrics=a,b,c[:type] that resolves the
requested metrics server-side under a bounded p-limit(4) with the profile
loaded once via the shared loadBaselineProfile, returning a map of the same
flat Derived<T> envelope keyed by the request token. Add the useDerivedBatch
hook + the insightsDerivedBatch query-key factory entry; the single-metric
route + hook stay for the per-score detail pages. The single route now also
adopts loadBaselineProfile instead of re-inlining the profile read. Honors
the existing 8s ceiling, retry:0, replace-with-fallback, and warms nothing
on visit. Register the new route in the OpenAPI contract.
The band primitives (score ring, coverage dots, contributor bars,
provenance chips + standard link, sparkline tint, trend arrow/delta)
painted straight from the raw `--dracula-*` variables, which carry no
`:root.light` override. On the white card the Alucard light theme uses,
the green/orange/yellow cleared roughly 1.1-1.5:1 — under AA — and the
`bg-dracula-yellow` confidence dot read near-invisible. The file comment
claimed they 'track automatically'; they did not.
Point BAND_NUMBER/PROGRESS/BORDER/VAR, the coverage-meter dot tint, the
provenance cyan chips, the sparkline stroke, and sentimentColorClass at
the semantic `--success`/`--warning`/`--destructive`/`--info` tokens
instead. Those alias the same Dracula tones in dark mode (pixel-identical
there, the primary target) but carry the darker AA-safe values under
`:root.light`. Clamp the score-ring provisional caption to one line so a
longer localised string cannot wrap over the ring arc.
Add a wellness-scores section to the vitals dashboard: a row of score rings for
Readiness, Recovery, Sleep, Stress, and Strain. Every ring is
data-availability-gated — a score with no underlying data simply does not
render, so the strip never shows an apologetic empty ring. Readiness and Sleep
are tappable and route to their existing score-anatomy detail pages; the
persisted nightly scores render read-only. Every ring reads the one
/api/insights/derived route through the shared useDerivedMetric hook.
Two parallel loaders for the generic derived-metric route had grown — a
components-local hook keyed on a 4-element tuple and a hooks/ hook keyed on a
3-or-4-element tuple. Both shared the ["insights","derived",metric,…] prefix
with different tuple shapes, which silently poisons the TanStack cache between
surfaces. Collapse to the single components-local hook (auth-gated, 8 s client
ceiling, retry-free) on the one insightsDerived factory key; the fourth slot is
always present so the metric prefix can no longer carry two shapes.
Build the composite tier of the derived-metrics layer on the shared seam:
- Sleep score — a transparent 0–100 composite from sufficiency, efficiency,
consistency, timing and composition sub-scores over the per-stage sleep
rows, reweighting around any sub-score the data cannot support (a legacy
asleep-only night drops composition gracefully rather than fabricating it).
- Wellness/readiness index — extends the health-score null-redistribution
blend with resting-HR, HRV (SDNN), sleep, respiratory-rate and mood
deviation-from-baseline components; returns insufficient below two present
components so it never headlines from one signal.
- Coincident-deviation flag — counts vitals outside their personal band on
the latest day and fires when two or more coincide, listing the
contributing vitals as possible factors, never a cause or a diagnosis.
Each composite cites its standard, carries coverage + confidence +
provenance, and reweights around missing inputs.
Add an FDR-controlled correlation discovery engine behind
GET /api/insights/correlations: it scans a curated behaviour x outcome
matrix, lag-joins each behaviour day to the next day's outcome, runs Pearson
with the exact Student-t p-value, and applies Benjamini-Hochberg control
across every tested pair so only statistically-defensible patterns surface —
each tagged with n, r, p and the adjusted q, framed descriptive not causal.
Add the score-anatomy detail view at /insights/scores/<metric>: a full
score ring, ranked contributor rows each showing its push/pull and weight
share, and the cited-standard provenance explainer — reused by every
composite, mobile-first and accessible.
Regenerate the OpenAPI contract for the new metric values + the correlation
discovery response, and add the i18n keys across all six locales.
Build the Apple-Health-Highlights grid of personal-vital tiles on the
Insights overview, backed by four new pure derived-metric compute
functions over the established seam:
- cardio-fitness band ("Fitness Age" frame) — VO2max placed against the
FRIEND-registry age/sex norm (Kaminsky 2015), surfaced + trended, never
re-derived.
- vascular-age delta — Withings vascular-age vs chronological age, a
relative wellness indicator (Vlachopoulos 2010 PWV framing), no medical
claim.
- HRV (SDNN) balance — reuses the typical-range engine for the band and
places the recent average as balanced / above / below; SDNN never
relabelled RMSSD; cadence-gated.
- BMI from weight + height — exact WHO classification, the fallback when
no device BMI exists.
Each metric carries coverage + confidence + provenance and cites its
standard through the provenance explainer. The dashboard renders one
SparklineDeltaTile per available vital: an absent vital does not render,
a still-building one shows the honest coverage meter rather than a
headline from too little history. Tiles read the generic
/api/insights/derived route through a TanStack Query hook keyed off the
centralised factory.
Regenerates the OpenAPI contract for the two new metric ids and adds the
vitals copy across all six locales.
Build the four reusable presentational components the v1.10 vitals and
score-anatomy surfaces share: a radial score ring, a coverage meter, a
sparkline delta tile, and a provenance explainer. Each extends the
existing dracula band + trend-sentiment vocabulary rather than a new
colour system, and ships its populated, provisional/empty, and stale
states up front so a sparse-data surface never goes blank.
- score-ring: centred tabular-nums number on a Recharts RadialBarChart,
band-coloured, size prop (sm tile / md / lg anatomy), count-up + sweep
on mount via a 0 KB requestAnimationFrame hook; role=img aria-label
restates the number so the ring is never colour-only.
- coverage-meter: CSS-only filled/hollow dots driven by the Derived<T>
coverage + confidence facets, with an accessible breakdown tooltip
(present vs required inputs, history days, missing list).
- sparkline-delta-tile: extends the trend-card grammar with an inline
Recharts area sparkline, a signed period delta, and an age/normal-range
framing slot.
- provenance-explainer: collapsible Popover (desktop) / bottom-sheet
(mobile) rendering inputs, plain-language method, and an optional cited
standard as React text children — no markdown library.
All four read their data off the Derived<T> union as a type-only import
so the client bundle stays free of the server graph. Recharts only, no
new runtime dependency. New i18n keys propagated across all six locales.
