Grip strength, pain (0–10 NRS), waist circumference, and waist-to-height
existed in the measurement enum, signal registry, and FHIR export but had
no web entry, no detail page, single non-sex-aware bands, and a split-brain
MCP exposure. This closes those gaps.
Web capture: the four signals join the manual measurement form, so a
web-only self-hoster can log them (the iOS client and the measurements API
already could).
Detail pages: flip detailPage on for the four signals and mount each on the
shared HealthKit metric template (chart, stat strip, Coach-read strip,
assessment card) via routed sub-pages and tab-strip pills, the same detail
spine every other metric carries.
Sex-aware bands: grip strength (EWGSOP2 men 27 / women 16 kg) and waist
(WHO men 94 / women 80 cm) now classify by the profile sex through the
age/sex norm resolver the assessment already threads; the resolver also
returns a sex-specific, age-independent band when no date of birth is set.
Fix the waist-to-height boundary so the NICE >= 0.5 rule is correct (the
last in-range value is 0.49).
MCP single source of truth: decouple the registry mcp facet from the Coach
snapshot — a signal can be MCP-readable without being on the Coach surface.
Mark the four physical signals mcp:true, derive the MCP rich-reads clinical
set from the registry flag instead of a duplicate allowlist, and relax the
invariant to coachSnapshot implies mcp (not the reverse). PHQ-9 / GAD-7 and
the environmental signals stay mcp:false and unreachable. compare_metric and
detect_changepoints now advertise clinical-signal support to match
get_metric_baseline.
Generalise sleep debt onto the existing per-metric source-priority picker
(a new sleepDebt ladder, native-above-computed, default WHOOP > Oura > Polar >
computed) instead of assuming one provider. The rhythm read resolves the active
source off the ladder and carries it on the DTO; when the active source is our
own COMPUTED engine — every user today, since no provider ships a native
sleep-debt balance — the Sleep page explains what the figure means and that it
differs from a wearable's native number. The computed model itself is unchanged
and correct (a short rolling balance of need minus sleep, surplus-credited);
only stale comments that still referenced the old 14-night window are corrected.
Add the medication-class to target-vital map and the adherence-to-vital
storyline so the Coach can surface, association-only, when an adherence dip
lines up with a drift in the vital that medication targets. Never causal,
never a dose-change suggestion; dose questions defer to the prescriber.
Add an in-repo CUSUM / binary-segmentation changepoint detector over DAY
rollups with a high firing bar (persistence plus within-segment-spread
magnitude) so the Coach can name a dated, sustained level shift instead of a
vague "lately", and stays silent when no break clears the bar.
Surface which source recovery is read from when two sources materially
diverge, with the honest reason, instead of silently averaging.
Lay the n-of-1 experiment substrate: a nullable encrypted outcome column on
coach_plans (migration 0197), the review_due / reviewed lifecycle statuses
wired into the encrypted-column registry and rotation script, and a daily
worker that reads the experiment result back in the user's own before/after
numbers — association-only, honest-null, no cheerlead on an adverse trend,
and routing a worsened vital to the clinician. The user-visible read-back
stays behind COACH_EXPERIMENT_VERDICT until its review cases clear.
Extend the outbound dose screen to catch experiment-shaped dose changes
(halve / skip / stop a medication to test it). Add evaluation cases and unit
tests for each new surface.
Replace the fixed three-beat assessment skeleton with a menu of moves the
model orders freely, and reframe the daily briefing from per-signal
enumeration to a verdict-first read that weaves the few salient signals into
one associative story. Score cards now name both the helped and the hurt
contributors, translate the band into a forward read for the day, and close
on one grounded nudge; the deterministic fallback gains the same band-meaning
sentence so provider-less and demo accounts read as well.
Add a hash-seeded opener-archetype rotation (deterministic, testable) so
consecutive cards and days no longer open the same way, a day-rotated sampling
seed for the period narrative in place of the fixed reference seed, and a
shared paragraph formatting contract. Add a score-number grounding gate and
extend the briefing grounding allow-set to the glucose, labs, preventive-care
and workout aggregate blocks so real figures can be cited without opening the
gate. Gate the daily score warm on an input fingerprint so a quiet day skips
the model call.
The A1–A3 source files carried v1.22.0 docstrings from before the work was
re-cut as the v1.21.2 point release. Comment-only sweep so blame and the
in-file version tags read consistently with the shipped version.
The builder is server-only by construction — only the metric-page route
imports it and it reads Prisma — and no other module in the tree depends on
the `server-only` package, so the import was both redundant and an undeclared
dependency. Removing it keeps the dead-code gate clean without weakening the
boundary.
Render a compact two-line "Coach read" above each metric sub-page chart:
an own-baseline line ("Your usual range is X–Y; today's Z sits within /
above / below") and one top lagged-association line from discovered
correlations, framed descriptively. It makes a metric read seen-in-context
rather than isolated.
The strip is server-authoritative: a new GET /api/insights/coach-read
resolves the band via the median ± k·MAD baseline engine (with its 7-day
history floor — below it the strip says "still learning your range" rather
than inventing a range) and the strongest on-metric driver from the
existing FDR-controlled, effect-size-floored correlation discovery (no
lowered floor; the line is omitted when nothing clears it). The client
component only renders the resolved DTO, so web and iOS read identical
numbers. DTO shapes and the pure selection logic live in a client-safe
sibling shared by the component and the unit test.
Wired through the HealthKit metric scaffold (every generic metric page) and
the bespoke weight, blood-pressure, and pulse pages.
The coincident-deviation read grouped the latest day with a UTC date
slice while the sibling readiness read already used the tz-aware day key.
For a user east or west of UTC, a late-evening or early-morning reading
landed on the wrong calendar day, so a fired flag could compare a vital
from the wrong day against its band and narrate '2 or more vitals out of
band today' on the wrong day.
Thread the user's timezone into the latest-day read and mint the day key
with userDayKey, matching readiness. The Coach derived-snapshot and the
correlations reader pass the real account timezone through. Adds a
regression covering a UTC+2 user whose late-night reading rolls to the
next local day.
The per-score deterministic text named the score, its standing, and the
weakest contributor, then stopped at the diagnosis. When the band is not
green and the weakest driver is behaviourally addressable (sleep, mood,
consistency, timing), append a single grounded pointer drawn from that same
contributor. Physiology-only drivers add nothing, so the text affirms and
watches rather than manufacturing a step.
The comment claimed the average-per-night, sleep-debt, and chronotype
cards share one window and cannot disagree. They each read their own
sub-window — the average over the full scorable span, sleep-debt over
its trailing 14 nights, chronotype over CHRONOTYPE_WINDOW_NIGHTS — so
the figures are each internally honest rather than identical, and every
card's caption discloses its own nightsCounted. State that plainly; no
computation changes.
Compute the mean asleep minutes per night from the same canonical
per-night data the sleep-debt and chronotype cards read, exposed as a
new averagePerNight field on the sleep-rhythm DTO. Surface it as a third
peer card with identical chrome, so the three tiles sit side by side.
Calm partial state under a four-night floor; localised in six locales.
The cumulative model summed every nightly deficit over a 14-night window
with no credit for catch-up sleep, so a sleeper a modest amount short on
most nights carried hours of standing debt that never recovered while the
pattern held. Replace it with a running balance over a 5-night window:
short nights add their capped shortfall, nights above need pay the balance
down at a sub-linear recovery rate, floored at zero. The headline now
reflects what is still owed tonight and shrinks as the sleeper catches up.
The readiness same-day grouping and the mood-streak anchor/walk both
sliced the UTC instant for their day key, mis-bucketing a late-evening
reading for a logger east or west of UTC. Thread an optional tz (default
Europe/Berlin) through both paths and key the buckets via userDayKey so
the day boundary follows the user's wall clock. Centralise the inline
day-in-ms literal in a shared time-constants module and use it here.
One-shot prettier pass so the new format:check gate starts from a clean
baseline. Formatting only — no behaviour change. Generator-owned and
vendored artifacts stay untouched via .prettierignore.
An active illness/condition episode annotates, it never penalises: the
measured number is untouched, only the narrative changes.
- rest-mode.ts: one server-authoritative resolver (module-gated, fail-soft)
for "is the account in Rest Mode + which episodes back it". iOS mirrors the
resolved context, never recomputes the suppression.
- health-score: /api/analytics attaches a value-free Rest Mode annotation;
computeHealthScore stays pure (score never adjusted).
- recovery-score: computeRecoveryScore carries the Rest Mode context as of the
scored day; the persisted blend is unchanged.
- coach-nudge: pause cadence-nudges during an active episode (new
skippedDuringIllness counter, gate sits before the trigger search).
- achievements: bridgeFrozenStreakGaps freezes (does not break) every
day-streak across illness days; never invents a streak, a non-illness gap
still breaks.
- coincident-deviation: reframe a fired flag as illness-explained; vital
numbers untouched. Surfaced as a neutral line on the insights card.
- coach snapshot: illness history + active illness as load-bearing context so
the coach knows about Rest Mode (no decrypted note reaches the prompt).
- FHIR: illness episodes map to Condition (generic disease root, label on
code.text, patient-reported/unconfirmed) + a bounding Encounter.
- doctor-report: module-gated illness section in the aggregator + PDF table
(retrospective, neutral palette); FHIR Condition section in the bundle.
i18n x6 for the report + reframe copy. Tests: score-annotation-not-
penalisation, streak-freeze, coach-nudge pause, FHIR Condition/Encounter
mapping, doctor-report inclusion, Rest Mode resolver. typecheck/lint/test
green, openapi in sync, knip clean.
Oura and Polar recovery rows are bucketed on the local day of their raw
measuredAt, on the assumption that both stamp the wake morning. Polar
always anchors at UTC midnight of the wake date and Oura falls back to the
same anchor when no real wake instant is present, so for a user in a far
negative UTC zone that anchor reads as the previous local evening and a
single night can split across two recovery days near the date line. A
correct fix needs an anchor-kind signal threaded through the recovery
read so the date-anchored sources read their wake day in UTC while a real
wake instant stays local — out of scope here. Document the assumption at
the bucketing site; positive-UTC users are unaffected.
Connect a Polar account over AccessLink v3: an authorization-code OAuth
flow (shared app from POLAR_CLIENT_ID / POLAR_CLIENT_SECRET) backed by a
stateless HMAC-signed state token doubling as an httpOnly cookie for CSRF.
The callback verifies the signature, expiry, provider binding, and the
byte-exact cookie match, then encrypts the access token plus member id onto
the user row.
An hourly poll-cohort job maps Nightly Recharge recovery, sleep stages,
and daily activity to canonical measurements tagged source POLAR, idempotent
on (userId, type, source, externalId). The recovery band feeds RECOVERY_SCORE
through the canonical ladder, which now ranks native readiness above the
computed proxy. Settings gains a connect / disconnect card. Tokens are never
logged or returned; every egress goes through safeFetch.
Make computeSleepRhythmFromNights own the chronotype look-back so the dashboard
summary (a year of nights) and GET /api/sleep/rhythm (six weeks) return the
same band, mid-sleep, and social-jetlag values rather than averaging different
samples. Derive the free/work day-type from the local wake-day digits so the
classification holds in far-east timezones, and read the shared sleep-rhythm
DTO type into the client hook instead of a hand-mirrored copy.
Compute cumulative sleep debt and the MCTQ chronotype server-side off the
canonical night reconstruction the Sleep Score reads, and render them on
the sleep page: a sleep-debt headline with a calm partial state under the
night threshold, and a chronotype card whose social-jetlag detail and
corrected mid-sleep sit behind an advanced disclosure. Both hold a learning
state on thin data and never assert a total or a band.
Serve the same values to the dashboard summary and a new GET /api/sleep/rhythm
read so the native client renders identical figures. Free vs work nights
default to weekend in the user's timezone until day-type tracking exists.
WHOOP stamps a recovery on the wake morning while the computed proxy files the
same night under the day that ended, a systematic off-by-one that left both
rows alive as two competing recovery days once the native series was read.
Resolve recovery by a source-aware wake-day key in the user's timezone — the
computed proxy's day is shifted forward to meet WHOOP's wake morning — so one
night collapses to one canonical row without re-dating the stored stamp and
without a backfill. Thread the same resolution through the wellness reader, the
coach nudge trend, and the coach snapshot, which had each read recovery raw.
The native WHOOP recovery and the computed proxy stamp the same night on
opposite clocks: WHOOP files the wake-morning instant (day D), the proxy files
noon-UTC of the day that ended (day D-1). Bucketing raw measuredAt by calendar
day leaves both alive as two competing recovery days.
Bucket each source by the user's local wake-day instead — shifting the proxy's
day-that-ended stamp forward one day to meet WHOOP's wake-morning stamp — so a
single night collapses to one canonical row while distinct nights stay
separate. Resolve the coach-nudge recovery trend and the coach-snapshot dedup
through the same path so no surface blends the two series or drops a genuine
native value on a numeric tie.
Nights with AWAKE rows but no IN_BED row (a common Apple Health shape)
lost their efficiency sub-score after the canonical reconstructSleepNights
migration, silently reweighting the composite and shifting historical Sleep
Scores. Restore the synthesised asleep + awake fallback on top of the deduped
per-night totals: keep the real IN_BED figure when present, synthesise when
only asleep + awake exist, stay null when neither.
RECOVERY_SCORE is written by two sources for the same day: the WHOOP-native
percentage from the device sync and the COMPUTED proxy from the nightly
readiness job. The wellness reader hard-filtered to source COMPUTED, silently
dropping every ingested native row, and the doctor PDF blended both sources
into one min/avg/max. The COMPUTED proxy also equals the readiness blend
verbatim, so the Coach prompt carried the same number under both READINESS and
RECOVERY_SCORE.
Add resolveCanonicalRecovery: per day, keep the WHOOP row when present, else
the COMPUTED proxy. Drop the COMPUTED-only filter for RECOVERY in the wellness
reader and resolve to the canonical row; STRESS and STRAIN stay COMPUTED-only.
Resolve the doctor PDF wellness summary the same way so the report reads the
native value, not a proxy/native blend. Dedup the Coach snapshot: omit the
recovery line when it mirrors readiness (the no-native case), keep it when a
WHOOP-native value differs. Document the WHOOP-over-COMPUTED resolution on the
sync delta feed, which already mirrors each row with its source so the client
resolves one canonical series rather than charting two.
A WHOOP-connected user's recovery tile, chart, and PDF flip from the proxy to
the native value.
Replace the divergent UTC-day night reconstructor in the Sleep Score with a
thin adapter over reconstructSleepNights, the shared engine the dashboard,
hypnogram, and doctor surfaces already read. The old path bucketed rows by UTC
calendar day and never deduplicated writers, so a multi-source night (WHOOP +
Apple Health for the same sleep) summed both writers and roughly doubled the
total. The adapter inherits session-clustering, local-wake-day keying, and
multi-source writer dedup, then derives the score-only fields the canonical
night does not carry: REM and Deep minutes from the stage map, the stage-
breakdown flag from any granular stage, and the midpoint from the asleep span.
Select source and deviceType in the Sleep Score read so the writer-dedup
ladder fires, and thread the user source priority through so the chosen writer
matches every other sleep surface. Round emitted asleep and in-bed minutes to
whole numbers, and round the per-stage map in the sleep-night DTO, matching the
integer contract the native client decodes.
A multi-source user's sleep score and the readiness score that folds it drop
once the double-count is removed, reflecting the true single-writer night.
A typed apiFetch wrapper owns the envelope unwrap, the ok-check and the
error read for every client call — two hundred call sites across the
app migrate onto it and a lint rule keeps raw api fetches out for good.
The legacy timezone helpers fold into the tz module and test fixtures
drop personal names.
The per-metric and wellness-score assessment prompts gain a premium-advisory
layer: name the earned win, build a little momentum, frame an unfavourable
finding as an opportunity, and close forward-looking. Every existing guard
stays in force — no platitudes, no bare number-echoing, autonomy-supporting,
never alarming, moralising or diagnostic, and the banned-opener and
forbidden-phrase lists are unchanged. The composite-score archetype warms to
a WHOOP/Oura-style recovery coach while staying descriptive, not clinical.
PROMPT_VERSION 5.0.0 -> 5.1.0 so the provenance can slice prose before/after
the tone edit. Cached accounts converge to the new voice within ~24h.

Add an additive, non-breaking assessment field to GET /api/insights/derived:
{ text, source, updatedAt } | null, keyed to the requested metric id for the
five per-score ids (READINESS, SLEEP_SCORE, RECOVERY_SCORE, STRAIN_SCORE,
STRESS_SCORE). The field is null when the metric is not one of those or when
its status is not "ok". A deterministic text always fills it — composed from
the score's own contributors, so provider-less accounts and the demo are never
empty — and warmer provider prose overrides it once cached, warmed out of band
so the GET never blocks on a model round-trip. de/en, following the v1.12.12
deterministic-narrative model. The batch grid read returns assessment: null;
the detail sheets use the single-metric route.
Introduce a shared buildMetricSignal() helper: a token-lean, signal-rich
descriptor (current, own baseline, signed delta, spread, normal-swing verdict,
normal-range placement, contributors) computed server-side so the model states
the comparison instead of re-deriving it from raw buckets. Thread it into the
generic per-metric assessment snapshot and lead the base prompt from it. Add a
PROMPT_VERSION constant to the base system prompt so prompt changes are
traceable.
Regenerate docs/api/openapi.yaml.

The generic metric-status generator read SLEEP_DURATION row-per-stage and
fed the snapshot a single sleep STAGE (~16 min) as the current value, so the
sleep prose reported a fraction of an hour for a full night. Route the
SLEEP_DURATION status/snapshot through reconstructSleepNights — the same
per-night, source-deduped, midnight-aware time-asleep total the dashboard,
series, and targets surfaces use — so the snapshot's series, summary, and
latest value are all the night total in minutes (the registry unit and normal
range are already minutes). Gated to SLEEP_DURATION; no other metric's status
path changes.
The readiness wellness index could surface a contributor value of 0 for an
account that recorded resting heart rate / HRV / respiratory rate but had no
scorable baseline: a non-finite baseline center or today value fell through
clamp100 to a misleading 0 that reads as a real worst-case sub-score. Return
null instead so the client drops the contributor, and document the null-vs-0
contract: null means no usable signal (no baseline, no recent reading,
non-finite input); a finite value — including a genuine 0 — means the baseline
is established and the latest reading really deviates that far.
(cherry picked from commit 0422ac012765f30069a41f662c2b025197ed9a88)
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.
The Enright & Sherrill 1998 predicted-distance equation was established on a
40-80 reference cohort; the metric accepts adult ages 18-120, so the
prediction extrapolates outside that range. State it in the user-facing
caveat (all locales) and the norms doc so a younger or older user reads
their percent-of-predicted with that honesty.
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 sleep midpoint was minutes-of-day in UTC, so a non-UTC sleeper's
consistency and timing sub-scores drifted with the offset (a 03:00-local
midpoint read as a different clock time than a UTC user's). Resolve the user's
stored zone in computeSleepScore and express the midpoint against it via the
existing tz helpers; reconstructNights takes an explicit tz (UTC default) so
the pure path stays test-pinnable.
The readiness + coincident-deviation latest-day-mean reads cap the row scan
on a dense intra-day day. Lift the bare 50 into a named MAX_LATEST_DAY_ROWS
constant and document the dense-intraday-retention reasoning at both call
sites so the bound is intentional rather than a loose literal.
The age/sex reference tables are coarse decade / paediatric brackets, so a
fractional age read a hard step at a bracket edge (39.9 -> 30s band, 40.0 ->
40s band). Anchor each band at its bracket centre and linearly interpolate a
fractional age between the two adjacent centres; below the youngest centre /
above the oldest centre hold the nearest cited band flat (clamp, never
extrapolate) so the band stays within the span of the two cited brackets and
the standard's provenance stays accurate.
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.
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 readiness and coincident-deviation composites passed historyDays =
windowDays (a constant) into deriveCoverage, pinning historyFraction to 1 so
a 7-day and a 30-day blend reported identical confidence. Pass the real
distinct-history-days backing the composite (the depth of the
best-supported present contributor) so confidence tracks actual depth.
The readiness provenance source was derived only from RHR/HRV/respiratory, so
a blend backed solely by sleep + mood could mislabel as DAY. Fold the present
sleep + mood provenance in so the source chip matches what actually backed
the headline.

The sleep-score consistency + timing sub-scores measured the midpoint as a
linear minutes-of-day difference, so a sleeper whose midpoint straddles
midnight (and any night across a DST shift) read a spurious ~24-hour spread
that inflated the SD and timing distance. Measure the midpoint on the
circular 24-hour clock (mod 1440) — a circular mean for the habitual midpoint
and a circular distance for the SD and timing offset.
Efficiency clamped asleep > in-bed (overlapping HealthKit stages) silently to
100, masking a data problem. Handle the overlap explicitly: a small overshoot
caps at the AASM ceiling of 100 (asleep cannot exceed time in bed), a gross
overshoot drops the sub-score because the in-bed denominator is not usable.

computeHrvBalance read recentAvg = baseline.value.center, which is the band
midpoint by construction and therefore always inside [low, high] — so the
"low" and "unbalanced" arms were dead and the card could only ever read
"balanced". Compute recentAvg from the last <= 7 DAY means (the recent
trend) and place that against the longer-window personal band, so a
suppressed recent trend flags "low" and an elevated one flags "unbalanced".

The Recovery/Stress/Strain crons fire in the small hours (04:45-04:55
Europe/Berlin, ~03 UTC) but scored the CURRENT UTC day, only a few hours
old: Strain missed the just-completed day's workouts and Stress saw a
near-empty intra-day SDNN set and falsely gated as insufficient. Score the
day that just ended (now - 1 day) across all three engines and their
measuredAt / externalId day stamps.
Resolve the previous-day key in one place by extracting the shared score-row
helpers the three engines each duplicated: scoreDayKey / scoreMeasuredAt /
scoreExternalId, the idempotent upsertScoreRow, and the cohort runScoreBatch
tally loop into src/lib/insights/score-row.ts; and loadBaselineProfile into
the baseline engine (the three byte-identical profile loaders + the partial
strain variant now route through it). The derived route should adopt
loadBaselineProfile too.

Register RECOVERY_SCORE / STRESS_SCORE / STRAIN_SCORE as derived metrics that
read the nightly-persisted COMPUTED Measurement rows — a passthrough, never a
recompute. The dispatcher routes the three ids to a thin reader that returns
the latest score, a trailing-window trend, and a direction-aware band (stress
and strain invert, so a high stress reads red). This lets every surface — the
dashboard, the Coach snapshot, the doctor report — consume the scores through
the one Derived<T> route + hook rather than each growing its own read path.
Regenerate the OpenAPI enum, which picks up the three ids from the registry.
Resolve the overlap where the vitals tier and the composite tier both extend
the derived-metric registry, dispatch, query-key factory, i18n bundles and the
OpenAPI contract: every derived metric (vitals baseline, fitness/vascular age,
HRV balance, BMI, sleep score, readiness, coincident-deviation) is now wired and
implemented, the dispatch test asserts the full set, and the locale bundles carry
both the vitals and the score-anatomy/composite strings.
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.
