Extend the mood-relations surface from mood to a health metric. For each
structured mood tag present on enough days, compare a metric's value on
tag-present vs tag-absent days: active energy on workout days (same day),
sleep length on nights tagged sleep (same day), and next-day recovery
after a tag like alcohol or food (D to D+1 lag). The comparison reuses the
existing statistics engine wholesale — the Welch two-sample t-test, the
per-group day floors, the confidence band, and the Benjamini-Hochberg FDR
control already used by the influence and discovery boards — so no new
statistics code lands. Only pairs that clear p < 0.05 and the FDR control
surface, ranked by adjusted q then absolute delta and capped at eight rows.
The result rides on GET /api/mood/insights as a new additive
`tagMetricCrosstab` field and renders as a confidence-gated, observational
card on the mood insights page, framed as an association in your own data
rather than a cause. The endpoint is server-rendered and not in the OpenAPI
contract, so no contract change is required.
Deprecate the standalone moodLog integration. Mood is now tracked fully
inside HealthLog through entries, structured tags, and rated factors, so
the external webhook and reverse-sync bridge no longer add anything. The
webhook route, the push and pull helpers, and the validation schemas carry
an @deprecated note pointing at the native path; the surface stays
functional this release and is slated for removal in a future major. The
settings card shows a deprecation hint, localised across all six locales.
Extract the Coach chat surface (header actions, message thread,
composer, provenance rails, settings, mobile trays) into a shared
<CoachConversation> component so the drawer and a new full-page route
render the exact same implementation — no forked chat logic. The drawer
keeps only its <Sheet> chrome (close button + maximize control); the
page supplies a minimize-back-to-drawer control.
The maximize control in the drawer header navigates to /insights/coach
and closes the drawer (aborting any in-flight stream); the page's
minimize control routes back to /insights and reopens the drawer through
the shared launch context. Both surfaces preserve incremental streaming,
collapsible history + provenance, the single composer disclaimer, the
auto-grow composer, refusal / budget handling, and the aiMode gating —
the full page redirects to /insights when the operator flag is off or
the user has opted out.
Lift useResettableValue / nextResettableValue into their own module so
the shared surface seeds its composer from the same controlled-prefill
contract without importing the drawer shell. Register the new route in
the coach feature-flag and per-user-disable gate-site invariants, and
add the maximize / minimize labels across all six locales.
The per-metric pages are the canonical home for each metric's primary
tile, target band, and correlation card. The overview was still
rendering its own correlation row (weight × weekday, mood × pulse,
BP × compliance) — the exact cross-view duplication to kill now that
the Weight and Pulse pages own those cards via MetricCorrelationCard.
Remove the on-overview CorrelationRow (component + test) and reorder the
overview toward the iOS Insights structure: hero (coach + briefing +
prompt chips) → detailed daily briefing → dynamics/alerts (today's
signal + rhythm events) → vitals dashboard → trends → period
retrospective → warm-assessments footer control. The overview carried
no target-tile grid, so nothing to remove there.
Drop the now-dead insights.correlationRow.subtitle key across all six
locales; title and disclaimer stay (the per-metric correlation card
still uses them).
Bring the web per-metric Insights detail pages to structural parity with
the canonical metric template: a single top-to-bottom spine, every block
self-suppressing when its data is absent.
New spine (above the chart): header (title + target gear + Coach circle)
→ intro → primary tile → Letzte Messung → stat strip; then the chart,
the range controls + period delta, the per-metric correlation card, and
the Einschätzung assessment last.
- Add the primary tile (headline value + 30-day average + an In-range
bar shown only when the metric carries a per-metric in-target pct).
Blood pressure keeps its richer target panel as its primary tile.
- Add the Letzte Messung card (labeled heading + last-reading date),
reading the last-seen timestamp the slim analytics slice already
carries — no extra fetch.
- Relocate the owning correlation onto its metric page: weight × weekday
on Weight, mood × pulse on Pulse. The card reads the correlations
already on the analytics payload and self-gates below the surfacing
bar; it is now the canonical home for those relationships.
- Move the headline value, 30-day average and in-target share out of the
target reference panel so each figure appears in exactly one place;
the panel stays the band reference (range, status, positional bar,
consistency strip, source). Blood pressure keeps its stitched S/D
30-day average inline.
- Order the Einschätzung last on every page.
Terminology: adopt the canonical labels — rename the mood patterns
surface to "Was auffällt", pluralise the deviation-count card to
"Signale des Tages", and align the settings section labels to
"Über diese App" and "Quellen-Priorität". New In-range /
30-day-average / Letzte Messung strings land in all six locales.
Web charts are unchanged — Recharts and the existing chart tokens
stay; the iOS monochrome chart doctrine is not applied.
Token-by-token streaming was buffering on the server. The chat route
enqueued every tokenised SSE frame synchronously inside the stream's
start() callback, so the runtime coalesced them into a single network
read and the client painted the full answer at once despite the
per-token render path already wired in use-coach. Make the emit callback
async and yield to the event loop between token frames so each one
flushes as its own chunk; the visible cadence now reads ChatGPT/Claude-
style. Refusal and error paths stay single-frame.
The conversation history was a permanent left column on lg+, eating chat
width on laptops and reading as a takeover behind the narrowed drawer
cap. It now lives behind an always-visible "Conversations" toggle on
every viewport and opens as the left-edge tray on demand; the thread
keeps the full width by default and never loses it on mobile.
The provenance block (source chips plus raw key-values) rendered fully
expanded under every answer and was often taller than the reply. Fold
the chips into the existing collapsed disclosure alongside the key-
values so the whole grounding is one click-to-expand surface, collapsed
by default, with the disclosure's aria-expanded/aria-controls intact.
The clinical-decisions disclaimer rendered both at the bottom of the
thread and in the sources-rail footer. Consolidate to a single line
directly above the composer, always visible on every viewport.
The auto-growing composer (single line growing to a capped multi-line
with internal scroll, Enter-to-send, Shift+Enter-newline) and the
aria-live streaming region are preserved. Plain-text React children
throughout; no new dependencies.
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.
- Mood discovery footer no longer pairs a mood-only numerator with the
full behaviour-by-outcome denominator. Reword it to surface the mood
relationships out of all day-to-day pairs the engine tested across
every metric, so the count it reports is honest about its scope.
Update all six locales.
- Rank the better-days board on a comparable scale: standardize the tag
mood-point delta into a Cohen's-d effect (delta over the pooled
with/without mood SD, clamped to [0,1]) so it sits alongside a metric
|r| instead of the old |delta|/2 heuristic. Fall back to |delta|/2 only
when the pooled SD is undefined. The pooled SD is ranking-only and is
stripped before the row enters the snapshot payload; the raw delta and
r the cards show are unchanged.
- Normalize the Withings and Whoop resume buttons to the min-h-11 scale
token, dropping the arbitrary min-h-[44px] spelling.
- Give the API token copy button a 44px tap target on small viewports,
scaling back to the tighter icon size from sm up.
- Drop the dead cached prop from InsightStatusCard and every caller; the
card has carried no cached affordance since the badge was removed.
Apple Health writes an unspecified ASLEEP aggregate alongside the granular
CORE/DEEP/REM partition for the same period. The asleep total already preferred
the granular partition, but the per-night/per-session `stages` map and the
hypnogram `segments` list recorded every stage row unconditionally, so a night
ended up carrying the granular set PLUS its ~equal bare twin — a double-height
green ASLEEP block on the stacked bar and the hypnogram, and a doubled total in
the analytics stage breakdown. Route the `stages` map and the `segments` list
through the same granular-over-bare gate as the asleep total: when a session
carries a granular stage, drop the redundant bare ASLEEP (and stage-less) rows
everywhere. WHOOP never emits a bare ASLEEP, so WHOOP nights are unaffected.
Apply the gate per session, not over the merged night pool, so a granular
overnight no longer strips a same-day bare-only nap's minutes from the night
total. Render the hypnogram per-segment in the stage palette (one ReferenceArea
per segment) instead of a single flat cyan line, and show the breakdown plus
totals footer whenever any per-stage minutes exist — reserving the unavailable
state for a truly empty session — so a legacy stage-summary night still surfaces
its breakdown. Thread the user's source priority into the CSV export's sleep
dedup, and honour offset with a true pre-slice night count on the sleep list.
Render the night's phase progression as a stepped depth track (Awake top
→ Deep base) over clock time, reusing the Dracula stage palette from the
stacked bar (now exported, no token reshuffle). Below it: the per-stage
breakdown (time + %), total asleep, time in bed, and the mid-sleep
awakenings count. One canonical source per night — Apple and WHOOP are
never overlaid.
Wired atop the sleep insights overview, gated on the same data-bearing
branch as the rest of the page so a source-less account never fetches.
New i18n keys under insights.sleep.hypnogram in all six locales;
query-key factory entry + measurement-write invalidation.
Apple Health (and some WHOOP shapes) write BOTH an unspecified ASLEEP
aggregate row AND the granular CORE/DEEP/REM breakdown for the same
sleep period. The per-night reconstruction summed both, so a real ~8 h
night surfaced as ~16 h across every sleep surface — the chart showed
~16-18 h points and the target-range 30-day average read ~16.4 h/day.
Prefer the granular partition: when any CORE/DEEP/REM stage is present
for a night/source, count only those; fall back to the bare ASLEEP (or
a stage-less legacy/manual) row only when no granular stage exists.
IN_BED and AWAKE stay excluded; dual-source nights still collapse to one
canonical source via the user's sleep priority ladder. The same rule
applies inside the per-source asleep tiebreak so a source writing both
shapes is not over-weighted.
Align the surfaces that bypassed the shared helper:
- insights/targets: SLEEP_DURATION was averaged as raw per-stage rows
(minutes) and fed into a target band expressed in hours, producing the
bogus 16.4 h/day. Reconstruct per-night time-asleep, convert to hours,
and classify + roll up consistency on the nightly hour totals.
- coach snapshot: route the sleep block through reconstructSleepNights
so the prompt narrates the same nightly numbers (was summing every
stage row, including IN_BED + AWAKE).
- sleep card chart: read /api/measurements/series?kind=sleep (night
reconstruction, hours) instead of the generic measurement
daily-average path, and label the axis in hours instead of minutes.
Add regression fixtures: a night with both a bare ASLEEP row and the
granular breakdown asserts the granular total (no double-count); a
dual-source night with both shapes per source; and a multi-night 30-day
average that lands at ~8 h, not ~16 h.
Both overview cards carried a min-h floor sized for their tallest state and
applied it to every state, so the calm everyday read left a large empty band
at the bottom.
- Today's signal: the min-h-48 floor now applies only to the tall `fired`
state; all-clear / watch / insufficient size to their short content.
- Period overview: the resolved card drops the min-h-40 floor and the footer's
mt-auto that pinned the timestamp to the bottom of the floored height.
The in-flight skeletons keep their min-h footprint, so the first paint still
reserves the row and does not shift as the read resolves.
The target gear painted a heavier 44 px box on mobile against the Coach
icon's flat 40 px, so the header cluster read as two mismatched icons.
Settle the gear on a flat 40 px box that equals the Coach sparkle on every
breakpoint, and restore the 44 px WCAG 2.5.5 touch target through a
transparent ::before overlay rather than a larger painted box. The shared
icon-button size stays untouched, so other icon affordances are unaffected.
Drop the top-right "cached" label from the assessment card — it surfaced
an implementation detail and read as if the insight were second-hand. The
warm cache still backs the text; the card just no longer announces it.
Mount the "show more" toggle only when the clamped prose actually
overflows three lines, measured against the live layout via a
ResizeObserver instead of a character-count guess. Short assessments that
fit no longer grow a toggle that reveals nothing, and text that wraps past
three lines on a narrow column now gets one.
Move the toggle copy off the inline locale-prefix fallback onto proper
`insights.assessmentShowMore` / `insights.assessmentShowLess` keys across
all six locales, and right-align the "last updated" line.
Two changes that turn the descriptive relations surfaces into a
statistically-gated discovery view on the mood page.
Mood as an outcome: the FDR-controlled all-pairs correlation discovery
engine treated mood only as a behaviour (a lag source). Promote it to an
outcome channel too, so the scan also surfaces "behaviour today → next-day
mood" relations (e.g. more daylight today → better mood tomorrow) alongside
the existing "mood today → next-day outcome" direction. The self-pair is
skipped and Benjamini-Hochberg already controls the larger pair family this
opens up. The discovery route now feeds the shared mood daily-mean series
into both roles.
Surface the discovery slice: the engine was computed but never rendered.
The mood Insights page now shows the mood-involving pairs that survive the
false-discovery correction, each phrased observationally with its paired-day
count, r, and BH q-value, plus the honest "X of N tested" footer. The
surface self-fetches the correlation route and degrades to nothing when the
operator has disabled it. Observational only, with the standing disclaimer.
Two new observational surfaces on the mood Insights page, both computed in
the single mood-aggregates engine so the charts and the coach snapshot stay
in sync.
Influence on mood (per tag): for each frequent flat and structured tag,
compare the average daily mood on days the tag is present against the
counterfactual baseline of days it is absent, with the delta and a
confidence band. The band comes from a Welch two-sample t-test reusing the
exact Student-t p-value already behind the correlation cards, not a naive
approximation. Both groups must clear a five-day floor; rows rank by
absolute delta and cap per axis. Sparse tags, single-day tags,
all-same-value days, and zero-delta tags are dropped cleanly — never NaN.
Better days board: one ranked list folding the tag deltas and the
mood x health-metric correlations (sleep, steps, pulse, weight, blood
pressure) into a single effect-size-ranked, confidence-gated surface — the
headline answer to "what goes with my good days?". Near-zero and
under-sampled correlations are excluded; the list is capped and observational
only, with the standing "association, not cause" caption.
Both surfaces ride the mood-status snapshot too so the assessment prose
never contradicts the on-screen relations. New copy in all six locales.
The target reference card carried an inline "Adjust target range" link,
which read as a control buried in a read surface. Lift the action to a
gear button in the category-page header, to the left of the Coach launch
icon, so the two sit as a consistent icon cluster beside the heading.
A small page-scoped provider bridges the two: the reference card
registers its editable target (one per page, except blood glucose which
fans out to several contexts and registers each) and the header gear
opens the per-metric editor sheet the provider owns. Single-target pages
open that target directly; glucose opens the primary context, since
target editing lives only on these pages — there is no separate targets
management surface. The card itself is now a pure read surface.
The gear carries the action's existing label as its accessible name,
clears the 44 px touch-target floor on mobile, and exposes a stable
`data-slot` for end-to-end coverage.
The per-metric target reference panel rendered on a borderless
`bg-muted/30` inset, which read as a nested detail block rather than a
top-level card. Side-by-side with the assessment, trajectory, trend and
recommendation cards on the same category page it looked off-tone. Match
the compact card surface those siblings use (`bg-card/20` tint, a
`border-border/40` hairline, the shared `rounded-lg`) so the panel reads
as one family.
Each Trends-row card carries a one-line caption below its mini-chart.
The first choice is the AI advisor's per-metric sentence, but on a cold
briefing — a web-only account, a pre-briefing cached payload, or the
advisor still generating — that sentence is null and every card fell
back to a static "Awaiting more data" hint, even with a full 30-day
series painted right above it.
Add a deterministic, rule-based descriptor derived from the same series
the mini-chart plots, and apply a three-tier caption precedence:
1. advisor annotation present → the AI sentence (unchanged).
2. else, a computable series → the deterministic descriptor:
direction (rising / falling / stable) plus the first-vs-last
magnitude over the window, e.g. "Rising over 30 days (+8 mmHg)",
"Falling over 30 days (−1.4 kg)", "Stable over the last 30 days".
Mood reads on a categorical 1–5 scale, so it is phrased in plain
terms ("Mood trended slightly higher over 30 days") with no raw
point delta.
3. else (genuinely < 2 points) → the real "Awaiting more data" hint.
The descriptor is observational and neutral by construction: direction
and magnitude only, with no causal, diagnostic, or medical claim and no
value judgement — a rising weight and a rising step count read the same
way here. A per-metric stability floor (the larger of an absolute and a
relative bound) keeps day-to-day noise from reading as a trend.
The descriptor logic lives in a pure, unit-tested helper. The caption
reads the same series the chart shows: mood reuses the existing
mood-analytics cache slot, and numeric metrics take a small dedicated
30-day daily-aggregate read keyed under a new query-key factory entry
that joins the measurement-write invalidation set. New descriptor copy
ships in all six locales. The pending shimmer while the advisor is in
flight is unchanged.
The Trends row renders three mini-chart cards (blood pressure, weight,
mood). The mood card alone overflowed: its categorical y-axis ("Super
gut/Gut/Okay/...") and date x-axis paint inside a Card shell that runs
taller than the flat HealthChart minis beside it, so the x-axis date
labels bled past the fixed chart slot and overlapped the caption below.
Bound the overflow on the slot itself, without touching the chart
components:
- `overflow-hidden` clips anything the inner chart paints past the
180px envelope, so a stray axis label can never escape into the
caption row.
- `[--chart-height:120px]` drives both mini charts' internal band down
to a shared 120px (both honour `h-[var(--chart-height,140px)]`). The
mood card's full envelope — band + header chrome + axis labels — now
fits inside 180px, so all three tiles share one chart-band baseline.
Recharts and the chart tokens are untouched; the fix lives entirely on
the row's slot container.
The hero strip, daily-briefing card and trends row all read the advisor
payload through `useInsightsAdvisorQuery`, which POSTed `/api/insights/generate`
without `force`. That POST generates inline on a cache miss, pinning the
page-load path on the full provider chain (up to the client's 8 s abort) before
the briefing paints — even though a read-only lift of `User.insightsCachedText`
costs nothing.
Add a read-only GET to the route that serves the cached payload immediately and,
when the cache is stale or missing and a provider is configured, enqueues an
out-of-band warm on the existing `insight-pregenerate` queue. The read mount now
uses the GET; user-initiated regeneration keeps the POST force path. Mirrors the
stale-while-revalidate posture of the per-metric status and period-narrative
reads — no provider call ever sits on a navigation request.
The "mood by time of day" card spans the full overview width, unlike its
distribution/weekday siblings which sit in a two-column grid. Sizing the
chart wrapper with aspect-[3/2] derived the height off the full card width,
so on a wide viewport the chart ballooned to roughly 800px tall and
overflowed its card. Swap the aspect ratio for a fixed bounded height so the
chart fits the card at the same size as the width-constrained sibling charts
regardless of viewport. Chart internals and tokens are unchanged.
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.
The thumb-up / thumb-down POST used to fail silently — on error the
buttons just reappeared with no signal that the submission had not gone
through. Add a lightweight localized error toast on failure while keeping
the success path quiet (the inline confirmation row is signal enough
there).
The recommendation cards carry `transition-all md:hover:-translate-y-0.5`
for a subtle lift on pointer hover. Motion-sensitive users got the full
transform with no opt-out. Pair the hover with
`motion-reduce:transition-none motion-reduce:hover:translate-y-0` so the
card stays put when the user asks for less motion.
Lift the disclaimer and feedback-thanks lines off the off-scale 10px
size onto the standard extra-small step. Unify the user and assistant
row gap, and budget the avatar column out of the bubble's 80% cap so a
bubble plus its avatar never overflow a comfortable width on a narrow
phone. Announce the empty-thread hero as a polite live region so screen
readers read the hint when the thread first mounts.
While a reply streams the composer now swaps the send button for a
visible Stop control bound to the abort handler, so a long or off-track
reply can be interrupted instead of waited out. Closing the drawer
mid-stream also calls the cancel handler, so the SSE request no longer
keeps running in the background after the drawer is gone.
Add a localised "Stop" label across all six bundles.
Replace the incomplete tablist/tab markup on the week/month toggle with
plain buttons carrying aria-pressed, give them a 44px minimum tap target,
and add a focus-visible ring. The visual treatment is unchanged.
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.
Add a calm "your week / month in review" summary to the Insights
overview, generated from the period-narrative context (deltas, personal
bands, FDR-controlled associations, coincident days).
- New insight_narratives table (migration 0113): one durable row per
(user, period, locale); generated prose AES-256-GCM at rest following
the coach-message precedent; labels-only provenance stays plaintext.
- generatePeriodNarrative feeds the context into the provider chain with
a tight, descriptive-never-causal prompt; an insufficient context
yields no narrative, a missing provider no-ops, neither fabricates.
- Nightly warm cron on week (Mon) / month (1st) boundaries, budget-gated
per user; the read-only GET enqueues a single-user warm on a cold read.
- Read route is stale-while-revalidate and never blocks on the provider;
the card renders plain text (no markdown), a single provenance
disclosure, and a fixed footprint (no CLS). i18n in all six locales.
Promote the volatile per-worker last-working cache to a Postgres
provider-health ledger so the fallback chain shares one health signal
across every instance, modelled on the atomic-upsert rate limiter.
The ledger holds a durable negative cache: an auth-class failure
(401/403) benches that provider for a cooldown instead of re-burning the
dead round-trip on every generation; a sustained hard failure backs off
briefly. The local model is never benched — it stays the guaranteed
floor of the chain. Every ledger interaction fails open, so a DB error
falls back to today's chain walk exactly.
When the user's primary provider fails auth-class, the Coach emits a
distinct credential_expired frame that deep-links to reconnect rather
than a generic "try again later".
Adds the provider_health table (migration 0112) and the
errorCredentialExpired copy across all 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 dynamic loader skeleton reserved 120px while the resolved card's
insufficient (~168px) and fired (~192px) states ran taller, shifting the hero
and everything below it down 48–72px on resolve. Pin a min-h-48 on the card
shell sized to the tallest realistic state, and match both the chunk-loader
skeleton and the in-component CardSkeleton to that footprint (including the
44px provenance header row) so there is zero shift across loading → any state.
Announce the fired state to screen readers via a polite role=status (not the
assertive role=alert), and mark the decorative loader skeleton aria-hidden.
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.
The show-all-readings link now carries the originating metric page as a
sanitised from param, so a weight to show-all drill-in returns to weight
rather than the Insights overview. The param is constrained to an internal
/insights/<slug> path so a crafted value cannot redirect off-site.
Lift the time-range pills + period-over-period delta block out of
HealthKitMetricPage into a standalone MetricRangeControls component that
owns the range pref, the range read, and the direction-sentiment lookup.
The HealthKit scaffold now consumes the shared piece so the bespoke metric
pages can render the identical control.
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.
When a derived wellness score (readiness or recovery) crosses a notability gate
— outside the green band AND confidence at least medium — the insights
generator now appends a SYSTEM CONTEXT block so the briefing can narrate the
shift observationally. Mirrors the GLP-1 plateau detector's append mechanism:
reads the one derived contract, returns null (the common case) at zero token
cost, and instructs the model to frame the signal as an observed pattern, never
a diagnosis or a dose recommendation. Add the readiness/recovery sourceMetric
enum values plus their briefing href + icon + trend-chart mappings.
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.
Add mapping tests for the five event classes (verdict resolution,
severity grading, the value-pinned-to-1 contract, unknown-codepoint
fallback, and that a continuous measurement never gets a classification),
the awareness-card gating + device-verdict framing + disclaimer presence,
and the events route narrowing + empty-state contract. Extend the enum,
chart-token and Coach-gate drift guards for the new event types.
Add a timeline of the health notifications the user's device produced on
its own, reachable from the Insights overview. The surface reflects the
device's own decision: each row reads "Your device flagged …" and a
permanent disclaimer states this is not a medical assessment by
HealthLog and that HealthLog does not diagnose any condition.
The surface is data-availability-gated — it un-mounts entirely when the
user has no such events, so an account that never triggered one never
sees an empty or alarming card. Copy renders as plain React text
children; no markdown library is involved.
Wire seven previously-deferred HealthKit quantity identifiers through
the full pipeline — enum, mapping, plausibility range, category, list-UI
metadata, FHIR coding, and the generic metric-status assessment:
CARDIO_RECOVERY heartRateRecoveryOneMinute bpm
WRIST_TEMPERATURE appleSleepingWristTemperature celsius
FALL_COUNT numberOfTimesFallen count
SIX_MINUTE_WALK_DISTANCE sixMinuteWalkTestDistance m
STAIR_ASCENT_SPEED stairAscentSpeed m/s
STAIR_DESCENT_SPEED stairDescentSpeed m/s
BREATHING_DISTURBANCES appleSleepingBreathingDisturbances count
Each value rides raw on the wire (identity conversion). Fall count is
cumulative (daily SUM); the stair speeds drain to a daily mean; the rest
store as latest per-workout / per-night spot readings. Wrist temperature
and breathing disturbances are flagged privacy-sensitive. The category
sleep-apnea and walking-steadiness EVENT identifiers stay deferred — they
are events, not quantities.
Each new metric gains an Insights sub-page on the shared scaffold with the
generic assessment card, localised across all six locales. Cardio fitness
(VO2 max) — ingested since v1.4.23 but assessment-less — gains its own
/insights/cardio-fitness page so it picks up the assessment instead of
riding as a bare chart-row on the pulse page.
Normal-range anchors are cited where defensible (six-minute walk 400-700 m,
ATS guideline + population reference); the rest defer to the user's own
baseline rather than fabricate a band.
Migration 0104 appends the enum values additively (IF NOT EXISTS, forward-only).
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.
