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.
Generic route mirroring the v1.8.7.1 metric-status precedent:
GET /api/insights/derived?metric=<DERIVED_METRIC_ID>[&type=<vital>].
apiHandler + Zod safeParse on the query, closed registry enum (unknown
id 422s via returnAllZodIssues), cookie-or-Bearer auth, userId narrowed
from the session (never a query field). The profile is read once and
passed into the pure compute function. Returns the flat Derived<T> union
in the standard { data, error, meta } envelope so the native client
decodes one stable shape and combines values across metrics.
Register the query + response schemas (DerivedMetricQuery,
DerivedMetricResponse + DerivedCoverage/Confidence/Provenance) and the
path operation in the OpenAPI registry; regenerate docs/api/openapi.yaml.
Add the route to the insights gate inventory (insightStatus-gated, no
Coach prose).
Route tests cover the 200 flat-envelope shape, session-narrowed userId,
422 on an unknown / missing metric, 401 unauthenticated, and the
insufficient flattening (null value + confidence, populated reason).
POST /api/insights/pregenerate warms the assessment cards — the comprehensive
insight plus the specialised status cards — all of which the read-only status
GETs gate on the insightStatus surface. It was gating on coach, so a user with
assessments enabled but the Coach disabled got a 403 and could not warm. Move
the gate to insightStatus to match the surface it actually serves, add it to
the route-gate inventory allowlist, and cover the coach-disabled-still-warms
path with a route test.

(cherry picked from commit ec041db6e2c81b95a429625bb765f1f41ebce40b)
Add POST /api/insights/pregenerate so every AI assessment text — the
comprehensive insight, the seven specialised status cards, and every
data-bearing generic metric assessment — can be warmed for the calling
user on demand, in the active locale, instead of waiting for the nightly
cron or a lazy first-visit generation.
The route narrows userId from the session/Bearer, runs the assistant
surface gate, and enqueues a forced full-warm job onto the existing
insight-pregenerate queue, returning immediately. A short per-user bucket
(insights-warm:<userId>, one per three minutes) returns 429 on a tight
loop so the bypassed nightly 20h budget cannot be turned into a provider
cost amplifier.
The worker branches on the payload: a job carrying { userId, force }
runs forceWarmUser for that user, skipping the candidate scan and the
20h budget; a scheduled tick with no payload keeps its existing batch
behaviour. forceWarmUser reuses the existing comprehensive generator and
warm helpers — no new generation logic — and stays safe by construction:
the comprehensive generator no-ops without a provider, the generic warm
pass filters to metrics the user has rows for so an empty metric never
reaches the provider, and every write is idempotent.
The queue name and a generator-free enqueue helper move to
insight-pregenerate-shared.ts, mirroring the insight-status-generate
split, so the route enqueues without pulling the generator tree.
Regenerate the OpenAPI contract for the new route.

(cherry picked from commit e10ae9bfeca544c7e5aecd9102459d97ddfad6db)
Derive `INSIGHTS_TILE_IDS` from `SUB_PAGE_SLUGS` rather than maintaining a
separate 14-id list. The layout tile-id universe and the routed tab strip
now share one source of truth, so a client can persist a layout covering
every metric page the web exposes (37 slugs + the overview mother page)
instead of tripping a 422 on the ~25 slugs the fixed allow-list did not
know about.
Rebuild `DEFAULT_INSIGHTS_LAYOUT` from the derived id list with an explicit
default-visible set; the long-tail HealthKit, body-composition, mobility,
and audio tiles stay default-invisible. The accepted set stays closed — an
unknown id still 422s — and the legacy German aliases keep round-tripping,
so no persisted layout breaks.
Regenerate the OpenAPI contract and extend the route deck: a PUT carrying
the previously-rejected slugs now succeeds, a full-universe PUT round-trips
through GET, and a genuinely-unknown id still 422s.

(cherry picked from commit 0a161d430533845b0c4c322047701b93aea49a06)
Extend the assessment-card system beyond the seven specialised scopes to
the ~30 HealthKit metric pages, without hand-writing a prompt per metric.
- Add a metric-metadata registry keyed by HealthKit id (display name,
unit, direction, optional normal range, archetype, scope), covering the
data-bearing HealthKit metrics. The seven specialised metrics keep
their own scopes and are excluded from the generic set; an unregistered
id gets no card.
- Add a generic data-driven generator that reuses the existing graded
snapshot, provider runner, stale-while-revalidate cache, and persist
path. One prompt template per archetype (physiological-vital,
activity-fitness, body-composition, mobility-gait,
environmental-exposure) plus a dedicated sleep template, parameterised
by metric metadata. Empty-data metrics return an insufficient marker
with no provider call. Normal ranges use age + sex where the profile
stores them; no ancestry/region ranges.
- Add GET /api/insights/metric-status?metric=<id>: apiHandler-wrapped,
Zod-validated against the closed registry id set (422 on unknown),
read-only with stale-while-revalidate. First insights route with
OpenAPI coverage; regenerate docs/api/openapi.yaml.
- Route the generic metric:<id> scope through the on-demand status queue
worker dispatch.
- Extend the nightly warm pass to the generic metric caches for a user's
data-bearing metrics only (one distinct read gates the set), keeping
de+en warm and never calling a provider for an empty metric.

(cherry picked from commit 41453fbdfee60793c16269b9a9e5f04b6c3ea450)
Opening an Insights category page froze the whole UI: the per-metric
status card fired a cold, uncapped LLM fetch on mount with no client
abort, so the request hung up to the server's 60s ceiling and the
pending/resolve re-renders thrashed the tab strip and ate touch events.
Timeouts were never negatively cached, so every visit re-blocked.
Fix the class holistically:
- Bound every status GET on the client. The shared use-insight-status
hook and the inline medication-compliance query now wrap fetch in an
8s AbortController and stop retrying inline; navigation can no longer
await an uncapped round-trip.
- Make the status routes read-only. On a cache miss the generator
enqueues an out-of-band pg-boss job (insight-status-generate) and
returns a preparing envelope; the client polls a bounded interval
until the worker warms the cache. Models the dashboard snapshot's
ready/preparing pattern. The queue is registered in the worker
allQueues loop + a boss.work handler, with a guard test.
- Fix the nightly warm-pass regression: warm every supported locale
(the client reads against the active UI locale, not the persisted
User.locale) and warm on a cached comprehensive outcome too (its
write still evicts the per-status caches). Add a short-TTL negative
cache on the timeout path so a transient provider stall no longer
makes every subsequent visit re-block or re-enqueue.
- Add loading.tsx for the insights segment + the root so any future
RSC await streams a skeleton instead of blocking the transition.
- Stabilise the advisor regenerate callback so a status-query flip
can't re-render the memoised tab strip mid-gesture.
New i18n key insights.assessmentPreparing across all six locales.
The tile-layout enum migrates from German to English to match the route
slugs. The contract on `GET/PUT /api/insights/layout` stays
non-breaking for clients that persisted the old German ids (the iOS
layout sync among them):
- the Zod enum is built from `ACCEPTED_INSIGHTS_TILE_IDS` (canonical
English plus the legacy German aliases), so a PUT carrying old ids
validates rather than tripping a 422;
- `normalizeInsightsTileId` collapses each legacy id onto its canonical
English replacement on both the read path (`resolveInsightsLayout`)
and the write path (`serializeInsightsLayout`), so a pre-rename layout
surfaces English ids on GET without a forced re-PUT and a legacy PUT
persists English ids;
- a layout carrying both a legacy and a canonical id for one tile
dedupes to a single canonical entry.
The legacy ids are accepted-but-deprecated. Tests cover the read-side
normalisation and the write-side 200 (no 422) + canonical persistence.
Rename every routed Insights sub-page slug from German to English
(`/insights/blutdruck` -> `/insights/blood-pressure`, `gewicht` ->
`weight`, `medikamente` -> `medications`, and the full v1.7.0 metric
tail). UI copy stays localised through `t()` keys; only the internal
slugs change. The slug registry in `src/lib/insights/sub-page-metric.ts`
is the single source of truth, so the tab strip, target summary, and
daily-briefing routing targets follow it.
`next.config.ts` `redirects()` emits a permanent redirect from every
legacy German slug to its English target, including a `:path*` variant
so nested routes survive. Bookmarks and cached PWA navigation keep
resolving.
Mirrors /api/dashboard/widgets for the insights surface: GET returns
the user's saved layout (defaulting to project order when unset),
PUT writes the layout, the response is the canonical shape the
clients can render directly. Closes the cross-device drift where
insights ordering lived in iOS local state only.
Storage is a new `insights_layout_json` JSONB column on `users`,
parallel to `dashboard_widgets_json` so each surface's resolver owns
its tile-id allowlist. Migration 0083 adds the column idempotently;
default NULL resolves to `DEFAULT_INSIGHTS_LAYOUT`. PUT routes
through the shared multi-issue 422 envelope + payload-redaction +
audit-row dedup pattern the dashboard-widgets route established.
A 5-minute per-user cache mirrors the dashboard-widgets cache and
busts on every save / reset.

`enforceBudget()` catches the cost dimension — once a user has burned
the day's token allowance the route returns 429 with
`coach.budget.exceeded`. It does not catch the request-rate
dimension: a tight loop or a stolen session can issue 60 requests in
a second, all accepted up to the moment the budget arithmetic
finally rejects, while pinning Prisma connections and provider-side
SSE slots in the meantime.
A `checkRateLimit("coach-chat:${userId}", 20, 60_000)` call lands in
front of the budget gate. 20 requests per minute is well outside any
realistic interactive pace — a human doesn't type that fast and the
iOS client paces from user gestures — while keeping the budget logic
as the cost ceiling it was designed to be.
The 429 returns through `apiError()` for envelope parity with the
other rate-limited routes; an `insights.coach.rate-limited`
wide-event lands so operators can see when the limit fires.

Eight touch-disjoint waves landed on develop before this release:
- W-INSIGHTS-HOT + W-RECONCILE-INSIGHTS — extract the timeout-stub
persist helper and wire all seven *-status routes through it, closing
the recurring ~14 s warm response the iOS client sees on dashboard
open once the AI provider has stalled once that day.
- W-DELETED-2 — close the remaining three soft-delete reader-tier gaps
(export bundle, gamification achievements, doctor-report aggregator)
with a five-route integration-test pin.
- W-ORG — types consolidation into src/types/analytics.ts and
src/types/backups.ts; prompt directory unification.
- W-FRONTEND-FACTORY — queryKey factory expansion + ESLint rule lift.
- W-IOS-COORD — POST /api/auth/check-user four-branch onboarding
discovery, identifier matched verbatim, per-IP rate-limited.
- W-SIMPLIFIER — today-intake projection helper extract; unused tx?
params dropped; 13 knip-flagged dead exports trimmed.
- W-PERF-OPS — v1.4.39 W-SUM legacy-NULL UNION discovery arm retired.
- W-PROCESS-DOCS — pg.Pool sizing operator doc; ESLint rule
formalisation; knip CI gate staged for v1.4.42 flip.
No migration, no env-var change, no API contract break for iOS v0.5.4.
The new check-user endpoint is an additive surface. AP-2 .p8 key is
installed; SB-5 time-sensitive APNs is live as of this deploy.
pnpm test --run green at 4732 passing / 1 skipped.
pnpm typecheck, pnpm lint, pnpm knip green.
Eleven touch-disjoint waves landed on develop plus a six-axis QA
reconcile round before tagging. See CHANGELOG.md for the user-facing
prose; this commit message documents the wave + report inventory for
release-management traceability.
Waves shipped (each with a phase report under .planning/):
- phase-W-POOL-v1440-report.md — p-limit(4) wrapper around the
analytics 15-way fan-out + pg.Pool max raised 10 -> 20. Closes the
v1.4.39 empirical-trace finding #1 (Prisma pool starvation).
- phase-W-DELETED-v1440-report.md — 11 reader-tier helpers + 3
integration contracts close audit Critical Finding #3 (soft-delete
invisibility) across dashboard, analytics, summaries, rollup tiers,
and the Coach snapshot path.
- phase-W-INSIGHTS-v1440-report.md — mood-rollup swap on the three
/api/insights/{features,targets,cards} routes plus the
compliance-rollup hook gap closure for bulk-projection mints; the
post-QA reconcile patch closes the six remaining measurement.findMany
sites in the cluster that still leaked tombstoned rows.
- phase-W-INFRA-v1440-report.md — rollup helper umbrella consolidation
under src/lib/rollups/* with zero orphan re-exports; lint, typecheck,
knip, and 93/93 rollup tests green post-restructure.
- phase-W-RSC-v1440-report.md — per-tile Suspense boundaries plus the
queryKey factory-bypass walker test (extended to comparison/ in the
reconcile pass).
- phase-W-PRIVACY-v1440-report.md — bilingual /privacy page with 17
paired-section tests pinning the 9 SB-3 disclosure requirements.
- phase-W-AASA-v1440-report.md — /.well-known/apple-app-site-association
endpoint pinned to S8WDX4W5KX.dev.healthlog.app with app-ID parity
assertions guarding against split rotation.
- phase-W-APNS-NOTIFY-v1440-report.md — MEDICATION_REMINDER
time-sensitive APNs payload (priority 10 + interruption-level)
scoped via a parameterised test that pins all 6 other event-types
do not bypass Focus. AP-2 .p8 install gates real delivery.
- phase-W-CONSENT-v1440-report.md — AI consent receipts CRUD with
append-only invariant pinned in test; revoke-then-regrant leaves
both rows; idempotent DELETE returns 200 + receipt: null.
- phase-W-WMY-WIRE-v1440-report.md — three previously-dead WMY readers
(week/month/year) wired through summaries-slice and
health-score-fast-path with a linear-composability parity test
pinning the cross-consumer routing contract.
- phase-W-GHOSTS-v1440-report.md — ~1 177 lines of dead code removed
across 9 atomic commits; startOfUtcDay + wallClockInTz consolidation
eliminates a sibling-drift risk; knip whitelist trimmed to three
files pending follow-up.
QA reconcile patches applied per the v1.4.40 QA round (six reports
under .planning/round-v1440-QA-*-findings.md):
- senior C1 — dashboard-suspense-boundaries regex aligned with the
post-W-INFRA Thread 2 userTimezone-local lift.
- senior H1 — soft-delete filter added to the six remaining
insights measurement.findMany sites.
- specialist H1 — Promise.allSettled around bulk-projection
compliance recompute on both /api/medications/intake and
/api/dashboard/summary.
- ux H1 — compare-toggle migrated to queryKeys.dashboardWidgets
factory; walker test extended to src/components/comparison/.
- security M1 — consent artefact 64 KB cap enforced via
Buffer.byteLength (UTF-8 bytes, not UTF-16 code units).
Quality gates green at tag: pnpm typecheck, pnpm lint, pnpm knip
--include files,dependencies,binaries,unlisted, pnpm test --run
(4726 passing / 1 skipped). Tests 4525 -> 4726 unit + 1 skipped over
the v1.4.39 -> v1.4.40 span.
User-facing prose: see CHANGELOG.md.
Robustness sweep, perf hotspots, full localization, coach gate
cascade closure.
- /api/dashboard/summary cold-mount 4.6 s → ~500 ms via DAY-bucket
sparkline + 60 s response cache.
- Coach API gate inventory test surfaced and closed two orphan
routes (chat[id] GET+DELETE, chat-message feedback POST).
- Cross-tz fast-path runtime guard falls back to live for users
more than ±3 h from UTC; proper bucket minting stays v1.5.
- es / fr / it / pl coverage 27 % → 63 % (~3 400 new strings) plus
three medication-cluster placeholder restorations.
- IANA timezone validation closes the User.timezone self-DoS
regression the new dashboard SQL would have surfaced.
- Unit suite 4520 → 4524.
See CHANGELOG.md for the full set.
Heavy-aggregate skip on the rollup-fresh + fully-covered path,
daily chart fetches opt into rollup buckets via source=rollup,
Insights extractFeatures swap drops the prompt payload from
double-digit MB to the low hundreds of kB on power-user accounts,
page-level isLoading gate replaced with per-section early-skeleton
paint, trends-row chart slot pinned for CLS, IntakeHistoryListV2
restored on the medication detail page, About card folded into the
Admin Console with an auto-checking update badge, cumulative metric
tiles read the day's running sum, IP-whois fallback surfaces city

additive users.insights_exclude_metrics column. Unit suite 4354
passing; typecheck + lint clean.
Hotfix on top of v1.4.34. The Insights page mount was paying ~29 s on
every cold load against accounts populated by the v1.4.34 Apple Health
importer. Root cause: `/api/insights/comprehensive` walked the unbounded
90-day measurement set into JS, then ran per-type `summarize()`, BMI,
blood-pressure classification, target adherence, and four Pearson
correlations from the same pile of rows. On a 100 000+ row account the
route consumed one of the 20 pool connections for the whole 29 s, which
cascaded sibling endpoints into Cloudflare "no available server" 503s.
The scatter-correlation card also surfaced a `width(-1)/height(-1)`
Recharts warning on first paint because its dynamic-mount lacked a
non-zero floor before aspect-ratio resolved.
Changed:
- /api/insights/comprehensive now reads through a SQL-side aggregator
(src/lib/insights/comprehensive-aggregator.ts) grouping by metric
type with Postgres-native AVG / MIN / MAX / REGR_SLOPE / REGR_R2 on
the measurements (user_id, type, measured_at) index path. Returns
the same DataSummary-shaped per-type bundle the legacy route
stitched together; the medication-compliance block keeps its
bounded Prisma reads. Wrapped through the server cache keyed on
`${userId}|comprehensive` (60 s TTL). Cold path drops from ~29 s
to a few hundred ms against fixture data matching the production
volume that triggered the bug; warm path resolves in single-digit
milliseconds.
- Cache-wrap the five remaining read routes the v1.4.34 server-cache
blueprint left staged but unwired: /api/mood/analytics,
/api/workouts, /api/bugreport/status, /api/medications,
/api/dashboard/widgets. The Cloudflare 503 cascade on
/api/measurements?aggregate=daily resolves as a downstream
consequence — once the comprehensive route stops monopolising the
pool, the origin accepts new connections fast enough that
Cloudflare's circuit-breaker no longer trips.
- /api/dashboard/chart-overlay-prefs PUT now invalidates the new
dashboard-widgets cache so the partial-update path doesn't leave
stale layout state in the cache for up to TTL.
Fixed:
- Scatter-correlation card no longer logs the Recharts
`width(-1)/height(-1)` warning on first mount. The wrapper now
carries a min-h-[180px] floor that matches the loading skeleton so
ResponsiveContainer always measures a non-zero parent before
aspect-ratio settles.
Operator-side assistant feature-flag matrix, /insights tab-strip blocking fix on mobile, and the GHCR-propagation-race Coolify auto-deploy fix. Full notes in CHANGELOG.
Bug-fix and consistency follow-through after the v1.4.27 mobile sweep.
The headline is a tighter dashboard and insights surface: six widgets
retire from code entirely (GLP-1 tile, dashboard `<DrugLevelChart>`
mount, GLP-1 detail-page intake history + inventory, the
`<InsightAdvisorCard>` block and its regeneration affordance, the
weekly-report route), four broken edges close (workout-edit duplicate-
timestamp 409, BD-Zielbereich tile rebuilt on the shared
`<TrendCard>` primitive, `/insights/puls` chart timeout fallback,
sticky tab-strip scroll lock), and one consistency contract lands per
maintainer directive: every medication-list row, every medication-
detail section header, every trend tile, every Coach launch glyph,
every chart-height contract reads on one shape. The HealthScore card
grows to fill its column, gains an accessible `?` tooltip explaining
the delta, and drops the placeholder "Wochenbericht erstellen"
button. iOS contracts are intact; the only `/api/*` evolution is
additive (the `aggregate=monthly` grain on `/api/measurements` and an
internal-only `/api/internal/web-vitals` beacon route).
Largest feature delta in the v1.4.x line. Insights expands into seven dedicated metric sub-pages; GLP-1 medication tracking lands end-to-end (drug-level chart with Research Mode acknowledgment, EMA titration ladder, cadence + compliance, side-effect taxonomy, pen/vial inventory); cross-source priority becomes a two-axis resolver; per-user timezone threads through ten analytics surfaces; Withings activity + sleep v2 sync; onboarding rebuilt as a nested-route wizard; Personal Records ship end-to-end; Health Score provenance accordion; Coach runs native first-party prompts across six locales with a 1800-assertion refusal-probe matrix; OpenAPI drift gate hard-fails; multi-arch GHCR image. Migrations 0043 through 0060 are additive and forward-only. PROMPT_VERSION 4.24.0 → 4.25.0 with GROUND RULE 9 (refuses dose recommendations) and GROUND RULE 15 (refuses drug-level estimates with MDR + MDCG 2021-24 cites).
See CHANGELOG.md for the full per-section delta.
Reviewer note: W5 H7 wrote Coach assistant prose plaintext into
recommendation_feedback.recommendation_text. Same prose lives
encrypted in coach_messages — backups captured the leak.
Migration 0042_coach_feedback_message_ref adds nullable coachMessageId
(FK + cascade) and drops recommendation_text. Aggregator joins +
decrypts on read; admin view reads through the same path.
Fixes: Sr-H3 (Wave-6 v1.4.23 senior-dev review)
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The v1.4.22 prose rewrite shipped without a way for users to signal
whether the new tone is landing. v1.4.23 H7 closes that loop with a
light-touch thumbs row + an admin first-week dashboard.
Schema: extend `RecommendationFeedback` with a polymorphic
`target_type` column (default "recommendation" so legacy rows stay
representative) plus a nullable `reason` field. New index on
(target_type, created_at) so the aggregator can scan per-surface
buckets without a full sweep. Migration `0040_recommendation_feedback_target_type`.
Route: POST /api/insights/chat/messages/:id/feedback. Body
{ rating: "helpful" | "unhelpful", reason?: string }. Verifies
ownership (404 on cross-account messages — no existence leak),
decrypts the message body for the dedup key, and writes the row with
target_type="coach" + a metric-source string encoding the user's
active prefs (`coach:tone=warm:verbosity=default`). Per-user 60/h rate
limit. 409 on a P2002 (already_rated) so a double-click is a no-op.
Aggregator: new `buildCoachFeedbackBuckets()` slices Coach rows by
(promptVersion, tone, verbosity). The summary blob the worker writes
to AppSettings.adminAiInsightsFeedbackSummary now carries both
`buckets` (pre-existing) and `coachBuckets` (H7 addition). Targets
the same singleton row so no second worker handler is needed.
Admin view: `/admin/coach-feedback` (new section slug) renders the
Coach buckets as a small DataTable (prompt version × tone × verbosity
× helpful × not-helpful × n × helpful-rate). Helpful-rate column
tinted via Dracula tokens (green ≥80%, yellow ≥50%, orange below).
First useful question this answers: "Is the v1.4.22 prose rewrite
landing well, or did the warm tone overshoot?" If the helpful-rate
for PROMPT_VERSION 4.23.x drops below 50% within the first 100
ratings, v1.4.24 walks the persona back.
UI: `<ThumbsUp>` / `<ThumbsDown>` buttons (lucide icons, no emoji)
under each persisted assistant bubble. Streaming bubbles + refusals
+ error bubbles skip the row so users can't rate before the message
lands on disk. Localised "Thanks for the signal." after submit.
OpenAPI: spec carries the new POST route + the request schema.
Coverage now includes the H4 + H7 routes — three additions over
v1.4.22 baseline.
Tests +9 unit (aggregator Coach-bucket slicing, admin section
render-paths) plus an integration round-trip for the route.

The v1.4.22 B5 audit removed the placeholder cog from the Coach
drawer header because it had no real wiring. v1.4.23 H4 returns
the cog with an actual settings surface backed by a per-user
preferences row.
Schema: nullable JSONB column `users.coach_prefs_json` (migration
0038_coach_prefs). Null = legacy v1.4.22 defaults; non-null carries
`{ tone, verbosity, excludeMetrics, showEvidenceByDefault }` validated
by the Zod schema in `src/lib/validations/coach-prefs.ts`.
Routes: GET + PUT `/api/auth/me/coach-prefs`. PUT validates the body,
persists the canonical defaulted form, and emits an
`auth.me.coach-prefs.put` annotation with the four-knob meta. OpenAPI
registry covers both verbs; the spec regenerates without drift.
Coach prompt builder: `getCoachSystemPrompt(locale, prefs)` prepends a
per-user OVERRIDE paragraph for non-default tone (neutral / concise)
and verbosity (brief / detailed). Concise tone forces brief verbosity
regardless of the explicit selection — concise == short. Default
prefs leave the prompt unchanged so the v1.4.22 train stays in place.
Snapshot builder: reads the prefs row BEFORE any measurement query
and intersects `excludeMetrics` with the resolved scope. The model
never sees data the user opted out of — that's the load-bearing
order: filter first, query second.
UI: settings cog in the drawer header opens a right-edge `<Sheet>`
with three Select pickers (tone, verbosity) and one Switch column
(per-metric exclusions + showEvidenceByDefault). Save calls the PUT
route and invalidates the `["coach-prefs"]` query so the next reply
honours the new defaults without a reload. EN + DE i18n keys for
every label and hint.
Message-thread reads the same `["coach-prefs"]` cache and toggles the
`open` attribute on the evidence `<details>` element when
`showEvidenceByDefault` is true.
Tests +24 unit (coach-prefs schema, system-prompt prefix, snapshot
mock for new prefs row). Integration round-trip seeds a session,
PUTs a non-default prefs shape, asserts the GET reflects the saved
values + the DB row carries the canonical defaulted form.

The W3-of-v1.4.22 sentinel parser silently dropped malformed rows and
fired `coach.keyvalues.parse_failed` only when the entire block was
unusable. Mixed-format drift (one row breaks, the other six parse)
landed without any signal. Surface it.
- `SentinelParseResult.malformedEntries[]` records each skipped row
with a typed reason (`missing_colon` / `value_overflow` /
`label_overflow` / `no_END_marker` / `byte_overflow` /
`schema_invalid`). Block-level failures (truncation, missing close
marker) land here as synthetic entries so the wide-event always
carries a typed cause.
- Per-row label and value caps moved out of the Zod schema into the
parser so the row-level reason can be `label_overflow` /
`value_overflow` rather than the catch-all `schema_invalid`.
- Chat route splits the annotation: `coach.keyvalues.parse_partial`
when at least one row parsed AND at least one row failed, the
existing `coach.keyvalues.parse_failed` stays for full-block
failures. Both annotations carry the per-line reason array.
- Backwards-compatible `parseKeyValueLine` wrapper preserved.
Tests +5: label_overflow, value_overflow, byte_overflow,
mixed-malformed entry assertions, and a tryParseKeyValueLine
direct-API surface check.

Six MEDs grouped per the W5 reconcile brief:
- Sec-MED-1: `hl_onboarding` cookie now `SameSite=Strict` (no
cross-site flow depends on it; sibling `healthlog_session` stays
`Lax` for the Withings OAuth callback).
- Sec-MED-2: `/onboarding` PUBLIC_PATHS match tightened from loose
`startsWith("/onboarding")` to exact path + subroute guard
(`pathname === "/onboarding" || pathname.startsWith("/onboarding/")`).
A future `/onboarding-export` route can no longer inherit the
silent-pass-through. Same guard mirrored on the redirect short-
circuit. Two new proxy tests pin the contract.
- Code-MED-3: lift `berlinDayKey()` from
`src/app/api/analytics/route.ts` to a shared
`src/lib/analytics/berlin-day.ts` and route the targets
sparkline-bucketing through it. The targets route used to bucket
by UTC `YYYY-MM-DD` so a 23:30-Berlin reading on Tuesday landed
in Wednesday's bucket. Four new unit tests pin DST + UTC-midnight
edge cases.
- Code-MED (streaming race): on slow connections SSE `done` fires
before the invalidate-refetch resolves, producing a 200-500ms
duplicate-bubble render. Add a 150ms grace window on the
message-thread that suppresses the persisted twin while the
streaming bubble is still in flight.
- Code-MED-2: drop dead i18n keys `insights.coach.settings` and
`insights.coach.settingsTooltip` (W3 removed the cog; the keys
had zero call sites and would carry confusing legacy if v1.4.23's
prompt-tuning panel picks a different key shape).
- Code-LOW-5: centralise `["user", "dashboardWidgets"]` query key
in `queryKeys.dashboardWidgets()` and migrate the three call
sites (dashboard, insights, settings/dashboard-layout-section).
Same query-key-collision discipline as `queryKeys.analytics()`.
Closes Sec-MED-1, Sec-MED-2, Code-MED-2, Code-MED-3, Code-MED-3
(streaming race), Code-LOW-5.

The Coach chat route had three identical `new ReadableStream({
start(controller) { try { ... } finally { controller.close(); } } })`
blocks (refusal / provider-error / happy path), differing only in
which frames they enqueued. Extract the boilerplate into
`src/lib/sse/create-stream.ts` so the v1.5 iOS streaming endpoints
inherit the same try/finally close semantics without copy-paste.
The helper accepts sync or async emit callbacks; the controller is
always closed in `finally` so a thrown emit never hangs the response.
Three unit tests pin the sync, async, and throw paths.
Closes Sr-H2.

When the model emits only a `---KEYVALUES---` block with no leading
prose (or a malformed block missing the closing marker), the
post-strip prose is empty. The previous fallback chained back to
`rawReply`, surfacing raw sentinel markers to the user. Replace with
a structured `coach.provider.empty` error frame so the UI renders
the localised provider-error copy instead of leaking the markers.
Add a regression integration test pinning that the streamed body
never contains `---KEYVALUES---` for a sentinel-only reply, and that
no assistant message is persisted in this branch.
Closes Code-H1.

Maintainer-voice sweep across `src/`. ~190 references to the
maintainer by first name in code comments and JSDoc neutralised to
"the maintainer", "the live tenant", "users", or "the user" depending
on context. Three sed passes covering ~50 distinct patterns
(`Marc reported`, `Marc wants`, `Marc kept`, `Marc rolled back`, etc.).
Test fixtures (`displayName: "Marc B."`, `username: "marc"`,
`<HeroStrip userName="Marc">`) kept as opaque test data per the brief.
CHANGELOG normalisation. The v1.4.14 + v1.4.15 entries paired a
German bullet with its English translation by historical design — the
in-app copy is English-default and the user docs are English, so the
mixed-language style was a holdover from the early-marathon notes.
A one-off node script extracted the `_..._` English paragraph from
each bilingual bullet and rewrote the entry as that text. ~44 bullets
reduced; one Docs bullet that lost a leading word in the regex
fixed by hand.
CLAUDE.md → CONTRIBUTING-AI.md rename so the filename is no longer
AI-vendor-specific. `CONTRIBUTING.md` reference updated. `AGENTS.md`
stays in place for multi-agent compatibility (the conventions doc is
shared with Codex / Cursor / etc.).
Wave-4 state wrap. STATE.md now records C1–C5 + D + D2 as complete;
v1421-backlog.md grew a "Closed in v1.4.22" header listing the 20
items the marathon landed; `.planning/phase-W4-report.md` documents
the per-commit decisions, test deltas, and the 23 items deferred to
v1.4.23 with reasoning.

The Zielwerte page read as a static reference cheat-sheet — every card
surfaced a current value + range bar but no recent trajectory. Each
target now grows a dependency-free 30-day sparkline beneath the range
bar plus a localised "Δ −2.3 kg vs. last month" caption so the page
reads as a living health log rather than a guideline lookup.
The API computes both fields from a single 60-day query (one round-trip,
not two): `points30d` is the daily-mean series for the last 30 days,
`deltaVsLastMonth` is the signed difference between the current and
prior 30-day averages. Both are null when either window has fewer than
3 readings so cold-start accounts don't see a misleading flat trace
or a "± 0" comparison that's really "no comparison".
BMI piggybacks on the weight series (divided by height²) so the BMI
card's sparkline matches its range bar's y-axis. Derived metrics
(BP-in-target rate, mood stability, medication compliance,
blood-glucose-by-context) keep their previous chrome — the rich
status surface they already render is the right answer there.

Add a text-marker sentinel parser (`---KEYVALUES---` … `---END---`)
that strips the Coach's evidence block out of the prose before it
streams to the client, validates each line against a Zod schema, and
attaches the parsed entries to `provenance.keyValues`. The persisted
envelope round-trips so the disclosure renders on conversation
reload. Hard-capped at 8 lines and 1 KB to guard against
prompt-injection padding; malformed blocks log a wide-event and pass
the prose through unchanged.

New `.planning/phase-v1421-hotfix-report.md` summarises the six
fixes (Daily Briefing regenerate · Coach day-level snapshot · Coach
prompt update · streaming-bubble dedup · drawer header · sources rail
scope picker), the test-count delta (2026 → 2036 unit), the
token-budget impact of the day-level snapshot (~190 → ~3000 tokens
per full-scope turn), and a recommendation to ship as a v1.4.20.1
hotfix.
STATE.md grows a Phase F section + status block tracking the six
commits on develop. Includes prettier polish across the touched
coach surfaces (sources-rail, drawer, message-thread, snapshot,
chat route).

The Coach snapshot used to ship only aggregated statistics (mean,
slope, SD, range, count) per metric. A turn that asked
"why was BP higher on Monday?" had no day-level rows to ground in
and the model fell back to apologetic aggregate-only phrasing
("from the snapshot I cannot isolate the specific Monday").
Extend buildCoachSnapshot to fold in:
- timeline.recent: one row per UTC day for the last 14 days, each
tagged with its weekday so the model can answer day or weekday
questions directly. BP rows pair systolic + diastolic; days with
only one side measured are dropped to avoid fabricating a
complement.
- timeline.weekly: ISO-week buckets covering days 15..N where N is
the configured window. Keeps the prompt budget tight on 30/90-day
windows while still letting the Coach cite older weeks.
- per-day medication adherence rows from MedicationIntakeEvent so
the Coach can answer "did I miss my dose Tuesday?" without
inventing the schedule.
Also add the optional `scope` field to coachChatRequestSchema (sources
+ window) so the upcoming sources-rail picker can narrow the snapshot
without breaking older clients — missing fields fall through to
all-source last30days.
A typical 30-day, 5-source snapshot lands around 2.4-2.8 KB JSON
(≈700-900 prompt tokens) — comfortably inside the 25k/day Coach token
budget.

The /api/insights/generate route was still calling the legacy
getInsightsSystemPrompt that returns the v1.4.5 {changed, stable,
drivers, …} shape and never asks the model for a dailyBriefing block.
GROUND RULE 8 (emit dailyBriefing when the snapshot has signal) lives
on getStrictInsightsSystemPrompt in src/lib/ai/prompts/insight-
generator.ts; the route never adopted it. Re-runs from the hero strip
therefore stored a payload with no briefing, the use-insights-advisor
lift saw null, and the briefing card painted its empty state forever.
Switch the route to getStrictInsightsSystemPrompt(locale). Existing
strict-shape tolerance is unchanged: insightResultSchema.safeParse
falls through to the raw parsed body on shape mismatch, and
aiInsightResponseSchema's passthrough() keeps any custom keys for
forward compat.

- Drop the withIdempotency wrap on POST /api/insights/chat. The wrapper
caches response bodies via cloned.text() then replays through
NextResponse.json(JSON.parse(...)) — turning the SSE wire format into
a null body on retry. The PWA never sends Idempotency-Key so the bug
is hidden today; the iOS client would walk straight into it. Dedup
still holds via the conversationId existence check + 20-turn cap.
- Read the SSE response body even on !response.ok when the content type
is text/event-stream so the structured error frame the route emits
surfaces its errorCode to the bubble. Without this the stream was
read only on 2xx and the rich error channel was dead code.
- Stabilise the useSendCoachMessage opts reference via useRef so an
inline-literal { onDone } from the drawer no longer re-memoises send
on every render.
- Drop the unused snapshot parameter from streamProviderError (the
ReturnType<typeof Object.assign> alias widened to any). Switch the
error response to status 200 so the streaming client reads the SSE
body and parses the error frame instead of branching on HTTP status.

GET /api/insights/chat returns the caller's conversations newest-first
with cursor pagination (default limit 20, hard cap 50). Each row
carries id, title, timestamps, and a message count so the rail can
render without paying the per-message decrypt cost.
GET /api/insights/chat/[id] fetches one conversation with every
message decrypted in memory before serialisation. Provenance metadata
round-trips alongside the assistant turns.
DELETE /api/insights/chat/[id] hard-deletes the thread; the FK chain
cascades the message rows.
Cross-user lookups map to 404, never 403, so the existence channel
never leaks across accounts.
6 integration tests cover the list ordering, owner-only filter,
decryption round-trip, and the 404 boundary on both verbs.

The route gates on requireAuth (cookie or bearer), enforces the daily
token budget, runs the prompt-injection / off-topic refusal scanner,
and only then walks the user's provider chain.
The conversation is created via withIdempotency() when no
conversationId is supplied, so a retry under the same Idempotency-Key
replays the original assistant reply rather than spinning up a second
thread. Existing-thread turns skip the wrap.
Replies stream as SSE: one "token" frame per word-sized chunk, then a
"provenance" frame describing the windows + metrics the assistant
could see, then a "done" frame carrying the persisted message id.
Provider failure cascades to a single "error" frame and the assistant
message is never persisted. Conversation history is capped at 20 turns
in the prompt window via a synthetic summary placeholder so cost stays
bounded.
`buildCoachSnapshot()` reuses the analytics features pipeline so the
Coach narrates the same numbers the dashboard tiles render.
`getCoachSystemPrompt()` extends the strict-insight ground rules with
conversational framing while keeping the zero-hallucination rule.
5 integration tests pin the round-trip, refusal short-circuit, budget
429, foreign-conversation 404, and validation 422 paths against the
postgres testcontainer.

The GET response used to surface the resolveProviderChain()-filtered
list, which DROPS disabled entries upstream. The Settings UI then
seeded `enabled: true` for every returned row, so disabling an entry
made it disappear on next refetch and lose its toggle position —
the toggle was functionally a "remove from chain" button.
Changed GET to read the *persisted* chain via parseProviderChain() so
disabled rows still round-trip with their flag. The active-provider
summary still uses resolveProviderChain so the displayed "Active: …"
line continues to reflect the actual runner ordering (enabled-only).
The Settings UI seeds entries with the wire-supplied `enabled` value
instead of always-true, so re-enabling becomes possible without a
page reload.
4 unit tests pin the GET shape (persisted-chain ordering, disabled
entries surfaced, cached-active overlay, default-chain fallback).

H5 — `POST /api/insights/feedback` had no rate limit. The unique
index `(userId, recommendationId, recommendationText)` blocks exact
replays but a malicious client could distort the daily aggregator's
bucket slice by varying recommendationId/text per request. Added
`checkRateLimit("insights-feedback:<user.id>", 60, 60 * 60 * 1000)`.
60/h is generous given a comprehensive insight rarely has >10 recs.
H6 — `<RecommendationFeedback>` invalidated the entire `["insights"]`
prefix on every thumbs click, which matches all 8 insights queries
(comprehensive + 7 per-status). None of them depend on the feedback
row. The 24h server cache absorbs the actual LLM round-trip but the
network thrash + stale-cache refetch was waste. Dropped the
invalidation; user-visible verdict state lives in localStorage +
local React state. v1.4.17's prompt-version ratchet will scope its
own invalidation when feedback feeds the next generation.

Extend `buildUserPrompt()` to accept an optional `ComparisonSnapshot`
that, when supplied, appends a SYSTEM CONTEXT block listing each
metric's current 30d average, baseline 30d average (from 30 / 365
days back), absolute delta, and percentage delta. The strict system
prompt gains a sixth ground rule that instructs the model to narrate
the most clinically-significant non-null delta in the summary's first
sentence and forbids inventing comparison numbers.
The route reads the user's persisted `dashboardWidgetsJson.compari-
sonBaseline` and builds the snapshot from a per-metric `summarize()`
sweep so the numbers the LLM sees match what the dashboard tile
renders — single source of truth for the comparison delta. Comparison
is default-on whenever the toggle is on per research §7 Q4: there's
no secondary "include in AI" preference, the pulldown is the single
affordance.
PROMPT_VERSION bumped 4.16.0 → 4.16.1 so the Wide-Event annotations
attribute responses to the new prompt revision.
Eight new unit tests pin: empty-comparison block render, EN/DE
locale switch, lastMonth vs lastYear language, the
"summary first sentence" instruction, and the anti-hallucination
"do NOT invent" guard.

v1.4.16 phase B5e: ship the POST endpoint that backs the per-rec
thumbs-up / thumbs-down UI. Body is the four rec-attributes the
client just rendered (id, text-snapshot, severity, metric-source +
time-range) plus the boolean verdict; server-fills providerType +
promptVersion via `resolveFeedbackAttribution()` so the client cannot
poison the daily aggregator's slice by claiming a thumbs-down was
attributed to a rival provider.
Idempotent via the existing `withIdempotency()` wrapper — a retry
with the same Idempotency-Key replays the cached response with
`X-Idempotent-Replay: true`. The dedup unique key on the model
(userId, recommendationId, recommendationText) returns 409 when the
same rec-text is re-rated — that's by design, the aggregator wants
per-text signal not per-id signal so a regeneration that rewrites
the same id with new text re-rates cleanly.
The attribution helper prefers `chainProviderType` over `providerType`
in the latest insights.generate audit row so when the B5b multi-
provider chain falls through to a secondary, the feedback row
reflects the working provider not the configured one. Falls back to
"unknown" + the current PROMPT_VERSION constant when no audit row
exists yet — the aggregator buckets that separately.
Audit row: action `insights.recommendation.feedback`, details carry
the feedback id, severity, helpful, providerType, promptVersion.
Tests:
- 7 unit tests for the Zod request schema (valid path, severity
poisoning, time-range poisoning, empty fields, stringified bool,
extra-field stripping)
- 5 unit tests for `pickProviderType()` priority + fallback
- 4 integration tests: 201 happy path with provider attribution,
409 dedup, 422 validation, fallback to unknown when no audit row

Cached insight blobs persisted before B5c shipped don't carry the
new `rationale` field — the strict parser would reject them, and
auto-regenerating on every cache-hit would burn rate-limit tokens
silently. Instead the route now detects the legacy shape and
surfaces a `legacyPayload: true` flag in the response so the UI
can render a one-time "regenerate for new explainability features"
CTA. User-initiated regeneration stays the trigger.
`isLegacyInsightPayload(payload)` lives in `src/lib/ai/legacy-payload.ts`
and is intentionally lenient: any rec missing rationale (or the
v1.4.14/v1.4.15 string-only InsightResult shape) flags. Empty
recommendations[] is NOT legacy — it's a legitimate refusal payload.
The annotate() Wide-Event also carries `legacyPayload` on cached
hits so the admin AI quality dashboard can chart the migration
ratio over time. v1.4.17 can flip auto-eviction on once the
ratio drops near zero.
7 new tests in `legacy-payload-detection.test.ts` pin the contract.
Existing 223 AI tests still green; typecheck clean.

The B5b read-only endpoint now has a write counterpart so the new
Settings → AI dropdown UX can save reorder + enable/disable changes.
Server-side priority is recomputed from insertion order (so the UI's
visual contract — "first row = priority 1" — cannot drift from what
gets persisted), unknown provider types and duplicates 422, and an
empty chain is rejected outright. parseProviderChain still falls
back to the default chain when the persisted JSON is malformed,
so a stale-tab resubmit cannot poison generation.

The AI section now renders a small read-only summary of the user's
fallback chain: "Active provider: ChatGPT (Codex)" plus "Configured
chain: ChatGPT (Codex), OpenAI (your key), Admin OpenAI". When the
in-process cache reroutes to a fallback (the primary 401'd in the
last hour), the line gains "(cached: OpenAI)" so the user can see the
runner has shifted without digging through the wide-event log.
The full management UX (drag-to-reorder, on/off toggles, add/remove
provider entries) is owned by phase B2 — this surface is deliberately
tight so the two phases don't collide. The card hides itself when no
provider is configured at all so accounts that haven't set up AI
don't see an empty header. EN + DE i18n keys added under
settings.ai.providerChain.*; provider-type labels are localised so
"Local model" reads "Lokales Modell" in German.
The new GET /api/insights/provider-chain endpoint is the data source.
Returns the resolved chain in priority order plus the cached active
provider (when set), wrapped in the standard apiSuccess envelope.

Same Apple-Health visual leap as the other charts, plus the mood-
specific affordance: an emoji glyph at every daily score so a week's
worth of mood reads at a glance without consulting the legend.
What changed:
- ComposedChart replaces LineChart so a gradient-filled Area paints
under the score line. The mood gradient uses the lavender token
(--dracula-lavender / #d6acff) which matches the existing line
stroke. Sibling 0×0 SVG mirrors the gradient for SSR-discoverability.
- Personal baseline reference line: median mood over the visible
window (≥5 points required). Faint dashed line labelled "Your
normal" / "Dein Mittel".
- Rich tooltip via RichChartTooltip — date label, score value with
text-label ("4.0 (Good)"), delta-vs-baseline sub-line.
- Emoji dot per score: 1 → 😖, 2 → 🙁, 3 → 😐, 4 → 🙂, 5 → 😄.
The Recharts `dot` prop accepts a function returning an SVG node;
we render <text> centred over (cx, cy) so the glyph sits on the
line. data-slot="mood-emoji-glyph" + data-score for visual probes.
- 600ms ease-out animation on first render, suppressed when
prefers-reduced-motion is set.
- Sparse-data placeholder via ChartEmptyState for <3 data points.
1 new test pins the gradient-defs SSR contract; existing
mood-chart-aggregation tests still green.
