The daily token cap was read before the provider call and recorded only
after a successful reply, so concurrent requests could all read
`spent < cap` and all hit the provider, and an empty/sentinel reply
recorded zero spend despite burning upstream tokens.
Reserve the budget atomically before the call: a single upsert-increment
returns the new total, so concurrent requests serialise on the row and
cannot both pass the cap; over-cap refunds the reservation and surfaces
`coach.budget.exceeded` as an SSE error frame. Reconcile the reservation
to the actual token count immediately after the provider returns —
before any empty/sentinel short-circuit — so burned tokens are always
recorded. An integration test proves two concurrent requests cannot both
exceed the cap and that an empty reply still records its cost.
The per-worker in-process "last working provider" hint stays volatile
and is deliberately NOT folded into the durable Postgres health ledger.
The ledger already shares the load-bearing skip signal across workers;
the only uncoordinated piece is a soft reorder whose worst case is one
redundant first-hop per worker per hour. Promoting it to a per-request
ledger write would add hot-path write amplification for a negligible
saving. Documented inline so the trade-off is explicit.
The grounding, tone/banned-opener, GLP-1 dose-safety, metric-identifier
ban and forbidden-filler rules were independently encoded across the
comprehensive, status, Coach and narrative prompts and had drifted. Move
the canonical wording into `prompts/shared-contracts.ts` (locale-keyed
fragments) and compose each surface from it.
Where the surfaces had drifted, adopt the stricter wording: most notably
the GLP-1 dose-prescription contract — previously present only in the
comprehensive and Coach prompts — now reaches the status cards and the
period narrative too. A cross-surface coverage test asserts every
enforced fragment appears verbatim in every surface, in de and en.
The comprehensive generator did an ad-hoc JSON.parse with no corrective
retry and failed cold to `invalid-json` on a first-pass miss, while the
strict insight wrapper's `buildRetryCorrectionMessage` sat right next
door. Export that helper and reuse it: on a parse miss, append the
correction to the user prompt and re-run the chain once before declaring
failure. Unifies the JSON-robustness story across the two paths.
The content-hash gate re-stamps the prior text whenever the snapshot is
unchanged, so the "daily" briefing read byte-stable day-over-day. Decouple
phrasing freshness from data freshness for the dailyBriefing.paragraph
alone: on a hash-unchanged hit, re-roll just the paragraph once per
calendar day at a higher, seedless temperature, keeping every structured
finding verbatim from the cached payload.
A new `insightsBriefingRerollDate` column gates it to at most one extra
call per day, and a re-roll miss still stamps the day so a failing
provider cannot be re-driven on every page-open. The hash gate stays
fully intact for the status cards (reference assessments — monotony is
fine).
Add an opt-in `responseFormat: "json"` to CompletionParams that the
structured surfaces (comprehensive briefing + per-metric status cards)
set. On local (Ollama / OpenAI-compatible) it adds `format: "json"`; on
Anthropic it prefills the assistant turn with `{` and re-prepends the
brace to the reply, so the first emitted token is already inside a JSON
object. Both cut the first-pass JSON-failure rate that fence-stripping
otherwise has to absorb.
OpenAI already pins `response_format: json_object` and is unchanged. The
period narrative (plain text) and the Coach (streaming prose) leave the
flag unset, so their non-JSON paths are untouched.
Add an optional `seed` to CompletionParams and thread it onto the
OpenAI and local (Ollama / OpenAI-compatible) request bodies. The field
is dropped when unset, so existing callers are byte-identical.
Pin a stable seed for the status/reference cards (defaulted in the
status provider) and the period narrative, so a prompt change is
diff-able against a fixed baseline rather than masked by low-temperature
non-determinism. Anthropic's Messages API has no seed knob, so its
client ignores the field (documented inline). The seed is annotated on
the narrative wide-event.
Replace the scattered `?? 0.3` / `?? 1000` temperature and maxTokens
magic numbers across the status provider, Coach route, comprehensive
generator and period-narrative generator with a single typed
`ai-budgets.ts` map. Each entry documents the output contract that
fixes its token ceiling.
Right-size the per-metric status output from 1000 to 250 tokens: the
card renders one `{ "summary": "..." }` of 2-4 sentences (30-60 words),
so 1000 was an order of magnitude over the real ceiling.
The floating Coach launcher inherited the button's dark foreground token,
which left the sparkle glyph as a dark outline on the purple-pink
gradient. The glyph is decorative and the button carries its own
accessible name, so the white mark reads cleaner without affecting the
control's non-text contrast, which the offset focus ring already
provides.
The expired-nonce callback test asserted the global fetch spy was never
called. A preceding successful-connection test fires its webhook
subscriptions fire-and-forget, and those promises resolve into the next
test's freshly installed spy, so the broad assertion failed whenever the
background calls landed in time. Filter the recorded calls to the token
endpoint and assert none reached it, matching the replay and cross-user
tests in the same file and keeping the check true to its intent.
KeyFindingRow and SignalRow rendered an identical tone bar + metric icon
+ headline/body/delta and the same link-when-routed behaviour, differing
only in their data-slot and body copy. Extract a single BriefingRow and
have both delegate to it.
The demo seed's random-walk BP generator could drift below the
physiological floor and mint a systolic-0 row (iOS #33). Clamp the walk
to the same band the input validator enforces (systolic >= 40,
diastolic >= 20), reusing the VALUE_RANGES floors, so a fresh seed never
writes a sub-floor reading. Add a read-side selection guard on the blood
pressure series endpoint that excludes rows below those floors from both
the series and the implicit latest point, so a corrupt row that slipped
in before the floor was enforced can never surface as the latest
reading. Export VALUE_RANGES so both sites share one source of truth.
Add aria-expanded to the coach drawer's history-collapse control so its
expanded state is exposed, matching the expand toggle. Give the Vorsorge
trend strip an sr-only summary of the latest value and seven-day
direction, and key the bars on measuredAt rather than the array index.
Remove the integration keys left dead after the integrations refactor:
the WHOOP and Fitbit overlap notes, the Fitbit experimental note, the
per-provider credentials-help strings (WHOOP, Fitbit, Polar, Oura) and
the Nightscout help. None carry a t() call site any longer. Add the
Vorsorge trend-strip screen-reader summary strings (latest value plus
seven-day direction) across all locales.
Add a coarseOnly option to buildTieredSeries that skips the raw 0–14d
read and the DAY (14–30d) / WEEK (30–90d) band reads, returning only the
MONTH / YEAR bands plus the anomaly envelope. The Coach snapshot's
coarse timeline tail consumes only month/year + anomalies, so the
near-term bands were read and discarded every turn; it now passes
coarseOnly. The briefing path is unchanged. Look the learn-guide prompt
example up by slug rather than by array index so reordering the catalog
cannot silently change the example link.
Drop steps from the signals-of-day set: Apple Health steps ingest as
many intraday stats-prefixed samples, so the newest raw row is a
partial-day fragment, not a daily total — same exclusion already applied
to per-night sleep. Add a glucose signal off the canonical stored value
(the model reads the snapshot, not display units) so the block matches
the priority comment that already claimed it; drop the dead sleep entry
from SIGNAL_PRIORITY. Track the raw extreme magnitude when keeping the
most extreme recent anomaly so a larger anomaly is no longer dropped by
comparing against an already-rounded value. Thread the injected clock
through trendSlope so the emerging-trend cutoff is deterministic under a
test clock. Rename the anomaly day-count to anomalyDaysAgo so the
snapshot hash staleness-tiers it instead of letting the raw count drive
the fingerprint. Cap the returned set at three to match the schema.
Wire the Coach snapshot's core-metric history onto the shared tiered
series so blood pressure, weight, and pulse carry a coarse tail the
in-window weekly fold could not produce — 90d-1y monthly and >1y yearly
buckets plus the preserved peak/trough envelope, so a spike from months
ago survives a coarse bucket. The tiered read skips the raw 0-14d band
the snapshot already holds, so no duplicate round-trip; the coarse tail
is bounded per band and sheds first under the prompt-budget degrader, so
token size holds.
Surface the active illness episodes and Rest Mode state to the Coach
prompt: the snapshot already carries the illness block, and the system
prompt now instructs the Coach to read an off-band vital as plausibly
illness-explained and avoid pushing a heavier cadence while the user is
in Rest Mode.
Add a static catalog of the public /learn guides and inject a compact
list into the system prompt. The Coach may reference at most one guide
by topic and URL when genuinely helpful, and only a slug the catalog
lists — a fabricated /learn URL is impossible by construction.
Every Settings → Integrations block now paints one consistent shape:
heading (icon + name + status pill) → a white primary description → a
grey secondary description that ends with the setup-guide link rendered
inline, instead of a standalone bottom-of-card element.
OAuth-only (WHOOP/Fitbit), BYO-credential (Withings/Oura/Polar) and
manual-key (Nightscout) cards share the same skeleton via the new
IntegrationCardDescription helper; the credential form stays as an extra
block where it applies. The "where to find these credentials" hint moves
above the Save button instead of sitting below it.
Rewrite the per-provider description strings across all six locales into a
parallel two-part shape with even length, and drop the now-orphaned
overlap/experimental sub-notes and the standalone setup-guide link.
Wave A removed the inline ask-the-Coach / suggested-questions block from
the overview hero (Coach is reached via the FAB + drawer). Update the
stale assertion that still expected onAskCoach/onPickPrompt + the launch
context on the page.
Remove the single-night "Last night" hypnogram from the sleep overview: its
per-stage breakdown (time + %) duplicated the phase-distribution stacked bar
directly below it. The /api/sleep/night route stays (the dashboard reads it);
only the redundant surface is gone.
Promote the chronotype to the prominent bottom block of the view. Split it out
of the rhythm section (now the sleep-debt headline alone) into its own section:
a large band label with the natural sleep-midpoint clock beneath it and an
expandable disclosure for social jetlag + MSFsc. It reads the same
["sleep-rhythm"] cache, so it adds no round-trip, and keeps the calm
"still learning your rhythm — N of M nights" state.
Fix the sleep-quality assessment slot. It disabled the status fetch whenever the
AI narrative was absent, so the card could not read hasProvider and fell back to
its no-provider default — surfacing the "connect an AI provider" CTA even for
accounts that have a provider connected, stacked under the grounded note. The
card now stays enabled and reports the truthful state: no provider shows its
clean AI-settings CTA alone; a connected provider with no text yet shows the
grounded note; warm or preparing AI text wins. Exactly one block fills the slot.
Redesign the Coach frontend toward a calm, prompt-first reading
experience:
- Narrow the reading column to a centred max-w-2xl with a roomier
vertical rhythm so the conversation reads like a document rather than
a packed log.
- Make the page-surface conversation rail collapsible and collapsed by
default. A single labelled toggle in the rail strip opens it (lg+),
the rail heading carries a matching close control, and the column
folds to zero width with a smooth grid transition. Below lg the
bottom tray is unchanged. The fullscreen header keeps only the
minimize control.
- Replace the boxy default scrollbar on the thread, history list, and
composer with a thin, rounded, subtle bar across WebKit and Firefox,
scoped to the components.
- Polish the pre-stream beat: the Thinking indicator now pairs bouncing
dots with the label, and the assistant turn fades in so the hand-off
to streamed tokens reads as one motion.
- Return voice dictation to the composer via the Web Speech API. The
mic mounts only where the browser supports recognition, dictates into
the textarea, and is keyboard- and screen-reader-accessible.
New labels land in all six locale bundles.
The score dials wore a token-tinted drop-shadow bloom, a conic specular
sheen, a breathing pulse on the green ring, and a dark-to-neon two-stop
arc gradient. Against the flat 2-D Recharts charts that read as a glowing
3-D gauge and made the overview restless.
Make the calm treatment the default everywhere, not only behind the `flat`
prop:
- Drop the bloom, the sheen, and the pulse for every ring. `.wellness-ring-arc`
is now a plain flat stroke; the sheen overlay paints nothing. The shared
cycle ring inherits the same quiet.
- Mute the arc colours toward the chart palette: the two gradient stops sit a
hair apart for a whisper of depth instead of a neon sweep, pulled down and
desaturated per hue in both the Dracula and Alucard sets. Band semantics
(green/yellow/red thresholds) are unchanged.
- `flat` now only drops the entrance sweep + count-up, so the dashboard hero
ring paints its value at once. The /insights strip keeps the subtle spring
fill; prefers-reduced-motion still zeroes it.
Score and band logic, thresholds, and the data-band/aria contract are
untouched.
Enrich the Vorsorge cards with a discreet 7-day trend strip and a path
into the underlying readings.
- A quiet seven-bar strip of the reminder metric's last seven readings
sits under the metric context on both the dashboard summary card and
the full-grid cards, mirroring how a dashboard tile carries a small
trend. Neutral muted bars, no status colour. A free-text reminder or a
metric with fewer than two readings shows nothing, so card height stays
stable. The strip reads a bounded last-7 window per type through the
existing measurements endpoint, cached by type under the measurements
invalidation prefix.
- The card kebab gains a 'Show measurements' item for measurement-linked
reminders that opens /measurements pre-filtered to that type.
- The measurements list accepts a ?type=<MEASUREMENT_TYPE> deep link that
seeds the existing client-side type filter while leaving the rail
interactive; unknown tokens are dropped. The ?add= behaviour is
unchanged.
- New labels added across all six locales.
Render the new signalsOfDay list at the top of the daily-briefing card — a
present-focused row (headline + concrete nudge) sharing the tone bar, metric
icon, and sub-page routing of the key-finding row, with matching typography
(text-sm headline, text-xs muted body) so the card reads consistently with the
rest of the insight surfaces. Add the signalsTitle string across all six
locales.
Remove the "Ask the coach" action button and the guided-questions chip strip
from the overview hero band: the Coach stays the bottom-right drawer mounted by
the insights layout shell. The hero is now greeting + subtitle + baseline meta
+ the optional Health Score panel, and no longer reads the coach flags or the
launch context. Update the coach-cascade / disable-cascade fixtures and the
hero-strip slot tests to pin the affordances absent.
Compute a present-focused "signals of the day" block in extractFeatures from
the in-memory measurement set (no extra query): the freshest reading vs the
user's own 7d/30d windows, the normal-swing verdict, an emerging slope, and a
recent anomaly per salient metric, ranked by clinical priority and capped at
five. Add a signalsOfDay array to the dailyBriefing schema feeding the
briefing alongside the existing keyFindings cap, and rewrite the briefing
prompt (EN + DE) to lead with NOW: a warmer, motivating read that surfaces the
emerging signal and gives one concrete, doable nudge while still drawing on the
tiered history.
The signals block lands inside the compacted features payload, so it also
seeds insightsSnapshotHash — a fresh daily signal now changes the fingerprint
and forces the daily 04:30 warm to regenerate instead of re-stamping a
days-old narrative. Bump PROMPT_VERSION to 4.29.0.
Introduce buildTieredSeries(): a five-band progressive data-context helper —
0-14d raw daily, 14-30d DAY, 30-90d WEEK, 90d-1y MONTH, >1y YEAR — plus a
per-metric min/max-envelope anomaly list so a peak from months ago survives a
coarse bucket. Reuses probeRollupCoverage / ensureUserRollupsFresh with the
existing replace-fall-back-on-miss contract; readers never throw, so a
coverage gap simply yields an empty band. Caps each metric near 600 tokens to
stay within the existing context budget. Shared across the Coach snapshot and
the daily briefing.
The health-record section (PDF + FHIR R4 export) was the only entry-point
gated on the doctorReport module's nav toggle, so flipping that opt-out in
the Modules hub made the whole section vanish from Settings with no
in-context way back. Drop the nav gate: the entry-point now always shows.
The doctorReport module still governs the data layer — the server-side
/api/export/health-record route stays the hard enforcement (403
module.disabled over Bearer when opted out). Assert the entry shows for a
default, empty, and opted-out modules map.
The message thread used h-full inside a plain-block wrapper, so its height
resolved against an auto-height parent: the scroll container grew with its
content instead of scrolling, pushing the composer down and leaving a stray
scrollbar on the page.
Make the thread wrapper a flex column and switch the thread (and its empty
state) from h-full to min-h-0 flex-1, so the scroll region takes a bounded
track from the flex parent. The conversation now scrolls cleanly inside the
card while the composer stays pinned to the bottom.
Mirror the medication card's name + cadence + status layout:
- the cadence ("alle 7 Tage") renders as a chip directly to the right of the
metric name via a new MedicationCardHeader nameChip slot, instead of on the
state-badge row below the category;
- the due / overdue status renders as plain text, not a chip;
- the "zuletzt erledigt" line always renders, falling back to an em dash when
there is no last-done value, instead of being hidden.
The green action button is unchanged. Also drop the per-module tour trigger
from this surface (the tour is first-time-only now).
The guided tour now exists only as the first-time auto-start after onboarding.
Remove every in-app trigger that re-opened it: the per-module "show this tour"
button on the dashboard, measurements, mood, medications, labs, illness, cycle,
achievements, insights, and coach surfaces; and the Settings replay card.
Delete the now-orphaned ModuleTourTrigger component, the tour-restart worker,
the healthlog:module-tour and healthlog:tour-restart event listeners, the
single-stop overlay path, and the force-launch session marker. The first-time
auto-launch gate and the tour overlay itself are unchanged. Prune the orphaned
i18n keys across all locales and update the affected tests.
The settings and admin shells reserved the page-heading height in the left
nav with a hidden replica block. The replica wrapped differently in the 220px
nav column than the real heading in the wide content column, so the first nav
item sat too low and drifted across locales.
Hoist the heading into the shell and place it in its own grid row spanning only
the content column: row 1 holds the heading, row 2 holds the nav and the cards.
The nav's first item and the first card now start the same grid row, so they
align by construction regardless of how the title or subtitle wraps. Drop the
spacer component.
Bump undici 8.4.1 -> 8.5.0 (GHSA-vmh5-mc38-953g, TLS certificate
validation bypass in the SOCKS5 ProxyAgent) and nodemailer 9.0.0 -> 9.0.1
(GHSA-p6gq-j5cr-w38f), both direct dependencies. Clears the production
high-severity dependency audit; no API change.
buildTargetBands was a same-file alias of buildDashboardBands, which the
dead-code gate flags as a duplicate export. Keep the historic name only as
a re-export alias from the snapshot module, so callers and the parity test
are unchanged while bands.ts exposes a single builder.
Cover the whole release — offline reads, cited reference ranges + Coach
grounding, responsible safety alerts + diabetes opt-in, the module tour,
the module-consistency and settings/admin IA pass, sleep/coach polish,
and the reminder completion route — and correct the additive migration
note (0173–0177).
Drop the health-score card's inert onAskCoach prop and its now-dead
pass-through from the hero strip, the buildDashboardBands re-export that no
caller reached through the snapshot module, an unused tour-progress status
type, and an orphan service-worker cache helper.
Drop the overstated claim that the due-reminder green button mirrors the
medication card (the med take button is always the default tone), fix the
module-tour anchor attribute named in a doc comment, and feed the active
section title into the settings nav spacer so its heading line wraps the same
way a long localized title does.
The dashboard recomputed the client band fallback on every render even when
the server snapshot supplied bands, and the module-list-prefs hook reparsed
its stored JSON into a fresh object each render, defeating downstream
memoisation. Wrap both in useMemo keyed on their real inputs.
Remove three diabetes settings strings whose web toggle was never built, four
dead reference-state explainer keys with no consumer, and the generic
reminder-toggle aria label that the per-row aria-labelledby wiring replaced.
The backend and resolver behind the diabetes preference stay in place.
The diabetes PATCH parsed its body without a size cap; bound it through
safeJson like the sibling routes. Label each reminder's enable/disable switch
by its own name span so screen readers hear the reminder rather than one
generic label repeated per row. Point the chronotype and illness disclosure
triggers at the regions they reveal via aria-controls.
The one-time disclaimer acknowledgment route shipped without an OpenAPI
entry, leaving a gap in the contract the iOS client consumes. Add the POST
path and regenerate the spec.
