Add averagePerNight to the SleepRhythmResource OpenAPI schema so the new
average-per-night card's field is part of the iOS-consumed contract (the
endpoint already returned it; the Zod source had not been updated, so the
in-sync check could not catch the omission).
Tag each vital return with whether it deviated in the illness-adverse
direction and tally only adverse returns when naming the recovery driver,
so a neutral move (e.g. weight drift) can no longer be surfaced as the
vital someone recovered ahead of.
The cross-episode summary already computes per-vital physiological returns
but the card surfaced only one bare line. Thread the dominant returning
vital through the aggregate and the DTO so the copy reads 'you tend to feel
better before your resting heart rate settles' instead of a context-free
gap figure.
The aggregate tallies which vital produced a real return across the
episodes that qualified for the typical-gap median and reports the most
frequent one (deterministic alphabetical tiebreak); the driver is named
only when a gap actually clears the magnitude gate. Zero new compute — the
returns were already in hand. Adds the localized copy in all six locales.
The cross-episode typical-gap median counts an episode toward its
qualifying-days floor via the per-episode coverage `historyDays`, which
counts a day if ANY banded vital has a reading. A WEIGHT-only episode (no
illness-adverse direction) could therefore clear the floor and feed the
median despite carrying no illness-relevant signal, weakening the honest-
sample claim.
Compute a distinct-adverse-day count in the engine — days with at least
one notable reading in the metric's adverse direction — and feed that as
the qualifying-days floor instead. Reuses the engine's single adverse-
direction predicate (now exported as `isAdverseDeviation`); a neutral-
direction vital never counts a day. The insufficient arm contributes 0,
which is correct since its gap is null and never reaches the median.
The full SNAPSHOT block (every cluster plus labs, illness, cycle and the
reference-grounding lines) was interpolated into the prompt on every turn,
so a one-word follow-up re-paid the entire grounding prefix. Ship it only on
the first turn, or once the history window starts eliding turns; on a cheap
follow-up send a short pointer back to the snapshot the model already received
earlier in the same conversation. The prior turns ride the transcript, so
grounding and cross-metric correlation are preserved while a follow-up turn
sheds about 6,000 tokens. Record snapshotSent and promptChars on the reply
annotation so the cut is observable.
The canonical rotation registry (src/lib/crypto/encrypted-columns.ts) is the
source of truth its guard test cross-checks; add EcgRecording.waveformEncrypted
there (the script already references it) and drop the redundant parallel guard.
Update the sleep/rhythm route test to the v1.19.0 rolling 5-night balance
(nightsCounted 5, debt 300) instead of the old 14-night cumulative sum.
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.
Extend the self-cleaning Telegram bot beyond medication. A mood reminder
now carries a 1-5 inline keyboard plus a "Note..." force-reply and a
"Later" action; a tap logs a MoodEntry (source TELEGRAM, server-side,
user resolved from the linked chat, idempotent on a per-tap externalId)
and confirms with a calm callback toast, no chat echo. An optional
free-text note attaches to that entry via the prompt-context correlation.
A measurement reminder carries "Done" (satisfies the cadence) and
"Later" (pushes nextDueAt forward) — completion and snooze only, no value
capture.
Prompts and replies self-clean in ~30 minutes: the window drops from 1h
and moves to a shared helper, the sender schedules an unanswered prompt's
deletion at send time, and the existing 15-min sweep also prunes expired
prompt-context rows. The webhook keeps the shared-secret + timingSafeEqual
+ rate-limit-before-secret posture; every write callback authenticates via
the stored chat binding. The Telegram chat id is added to the egress
redaction denylist.
The comprehensive briefing's bounded feature read (extractFeatures) was
paid more than once where it should not be: the on-demand route and the
shared generator each run a downgrade ladder that re-reads with identical
arguments, and a nightly warm has no shared object across consumers in a
single tick.
Add a request/run-scoped feature cache: withFeatureCacheScope opens an
AsyncLocalStorage store, getCachedFeatures memoises the first compute per
(userId, day, includeRaw, sinceDays), gated on a cheap salient-input
fingerprint so a mid-scope ingest recomputes and a probe failure fails
safe. Outside a scope it is a pure passthrough. Wired into the
comprehensive generator, the on-demand POST handler, and the nightly
per-candidate loop + forceWarmUser. Coach keeps its own snapshot.
Define the go-forward aggregated heart-rate upload shape so clients can
stop posting one Measurement per raw HealthKit sample. A heart-rate row
keyed `stats:HKQuantityTypeIdentifierHeartRate:<bucket-start-hour>`
carries the hour's average bpm as a single PULSE row and rides the
existing `stats:` overwrite path: a re-post within the hour overwrites
the value instead of duplicating, identical to the per-day cumulative
rows. The hour boundary is UTC so the key is timezone-stable.
The batch route rejects a row that targets the heart-rate bucket prefix
with a malformed hour suffix as a per-entry skip
(`malformed_hr_bucket_id`) rather than persisting an un-overwriteable
row; well-formed buckets, per-sample uuid ingest, and the per-day
cumulative overwrite path are all unchanged.
Average-only for now — the measurement row carries a single value
column, so hourly min/max would need a schema change and is left as a
follow-up. Documents all three externalId shapes plus the `updated`
status in the OpenAPI contract.
The medication detail clients computed the supply headline in the browser
via summariseSupply, risking web/iOS drift and pulling the shared math
into the client bundle. The GET /api/medications/[id]/inventory route now
computes the canonical SupplySummary server-side through summariseSupply
(the single source of truth) and ships it in the DTO; the Bestand and
Übersicht surfaces render the ready figures. Adds the MedicationSupplySummary
schema to the inventory list response and regenerates the OpenAPI contract.
The v1.18.11 briefing now folds illness-episode and cycle state into the
prompt via buildBriefingIllnessCycleContext, which resolves module gates
through memoizePerRequest and queries cycleProfile. The generate route test
mocks neither getEvent nor the cycle/illness models, so every case threw once
the new call path ran. Stub the context module to no output and add the
getEvent export to the logging-context mock so these cases stay scoped to the
provider and cache behaviour they assert.
Serve achievements via SWR and precompute Berlin day-keys to kill the per-row
Intl cost; switch dashboard/summary to cachedSwr; lazy-load three charts that
bypassed the dynamic boundary.
Achievements: the bucket was 60 s hard-TTL while the app-wide unlock
notifier polls every 2 minutes, so every poll landed on an expired
entry and fired a cold ~400 ms rebuild in the foreground. Add a
10-minute stale-while-revalidate window and read the route through
cachedSwr; the route already persists pendingUnlocks outside the cached
factory, so a stale serve never skips an unlock write.
Achievements builder: the vitals array ran through several full-array
passes, each re-deriving a Berlin day-key (and hour) per row via
Intl.DateTimeFormat. Compute each row's day-key once and thread the
parallel array into the green-day, weekly-consistency, engagement, and
hidden passes; the hidden pass reuses a single precomputed hour array.
Results are byte-identical to the per-row derivation (parity test added).
dashboard/summary: read through cachedSwr so the iOS-polled endpoint
serves its existing 1 h stale window instead of re-paying the cold
rebuild every 60 s on the plain cached path.
Charts: route the three recharts consumers that bypassed the shared
next/dynamic boundary (lab biomarker chart, sleep stage stacked bar,
recommendation rationale charts) through dynamic imports with matching
loading skeletons, taking recharts off the first-load JS for
/labs/[id], /insights/sleep, and the insights recommendations surface.
Bound the comprehensive briefing's feature read to a 400-day window instead of
walking the full measurement history on every generation. All-time min/max/avg
are sourced from one grouped aggregation over the whole history, so the
allTime* fields stay honest while the unbounded row materialisation is gone;
the oversize downgrade ladder remains as the safety net.
Fold illness-episode and cycle state into the briefing prompt, reusing the
server-authoritative builders the Coach already assembles. Both are
module-gated and cost nothing for users without them, so a mid-illness or
mid-cycle user finally gets context-aware prose.
Ground daily-briefing numbers against the signal features, guard Coach replies
against fabricated doses and risk scores, gate the period narrative, feed the six
status cards a precomputed signal block, add SSE cancellation, and cap the Coach
snapshot read.
Apply the outbound safety screen to the assembled Coach reply before
persistence and streaming, with a per-turn audit row on a block.
createSseStream gains a cancel handler + a shared AbortSignal: a client
disconnect now flips the signal so the token-emit loop stops enqueuing
into a closed connection and any provider fetch wired to the signal is
torn down. The chat emit loop honours it between frames.
The daily-briefing block (paragraph / signalsOfDay / keyFindings) was
schema-shaped but never number-checked the way recommendations[] are: a
restated figure could drift from the snapshot with no server rejection.
Add a grounding cross-check that asserts every number the briefing prose
states traces to a features.signalsOfDay figure (latest / avg / delta)
within a rounding tolerance. Wire it into both generation sites with one
corrective retry, then strip the briefing rather than persist a
fabricated number. Also gate the higher-temperature paragraph reroll on
the same check so a phrasing reroll cannot drift a figure.
Add an opt-in in-browser OCR path so a user whose provider cannot read
images (ChatGPT-OAuth/Codex, a text-only model) can still scan a lab
report. The capability probe gains a `mode` field: `vision` when the
provider reads the image directly, `text` when local OCR is enabled and
any provider is configured, or null. The extract route grows a text
branch that accepts the in-browser-OCR'd text as JSON and structures it
through the existing schema + review/commit flow; the raw image never
reaches the server in text mode. New `labsLocalOcrEnabled` user column
(migration 0184, default off) gates it, with a dedicated PATCH endpoint.
The per-row commit loop ran isDuplicate() then create() sequentially, so
two identical rows in one confirmed document only collapsed because row 1
autocommitted before row 2's live query. Track written keys in a
per-request seen-set keyed on analyte+day+value so in-batch dedup no
longer depends on DB visibility. Note the mint-then-create orphan on a
mid-row failure is benign and self-healing, matching the manual path.
The in-app measurement routes evict the snapshot cache, but the iOS
batch ingest and the server-side Withings sync only marked it stale (or
never touched it), so a focus-refetch could serve pre-sync data for up
to the snapshot TTL. Route both background-sync entry points through a
hard evict so returning to the dashboard surfaces freshly-synced rows.
Add the OcrCapability, OcrExtract, and OcrCommit operations under
/api/labs/ocr/* and regenerate the YAML. Document the multipart upload, the
untrusted-extraction contract, and the source OCR commit value. Mark the three
routes exempt in the module-route gate inventory under the labs data-layer
reasoning.
Resolve a vision-capable provider, gate with consent + a 6/hour rate bucket +
a reserved per-day token budget, then transcribe an uploaded photo or PDF into
structured proposed rows. The raw upload stays in memory only and is never
persisted. The commit route writes only the rows a human confirmed, resolving
or minting a biomarker per row with source OCR and skipping commit-time
duplicates. The capability probe drives whether the UI shows the scan entry.
Extracted text is treated as untrusted; the review screen is the safety
boundary.
Rebuild the /coach surface as a centred-hero chat with a word-by-word fade, a
single thinking disclosure, and a per-message token footer; emit token usage on
the done frame and persist it via migration 0182; plumb an additive reasoning
frame with an elapsed-time fallback for non-reasoning providers.
Invalidate the dashboard snapshot on measurement writes and refetch on focus so
fresh and background-synced readings surface without a hard reload; expose the
no-provider state on the briefing read with a connect-a-provider hint; align the
briefing footer caption.
An account with no AI provider configured still reads the last cached
briefing — the read path serves it without ever touching a provider — so
the days-old report rendered as current. The pregenerate cron runs fine;
the cache simply can never refill without a provider. Report provider
availability from the read GET and pair the briefing's relative age with a
discreet 'this can't refresh — connect a provider' hint linking to
Settings -> AI, on both the overview hero meta row and the briefing card
footer. The hint only shows when a briefing is actually rendered; the
empty-state already owns its own no-provider branch.
Also align the briefing card footer caption to the 11px scale the
adjacent period-in-review card uses, so the two overview footers read at
one size.
Carry an additive usage envelope on the SSE done frame
({ totalTokens, model }) and persist tokensUsed + model onto
coach_messages (migration 0182, nullable, no backfill) so the
per-message token footer survives a conversation reload. Add an
optional reasoning frame the client can render inside the thinking
disclosure when a reasoning-capable provider emits a summary; providers
without reasoning emit none. Extend CoachMessageDTO and regenerate the
OpenAPI contract. Server-authoritative: clients display the count, never
recompute it.
The illness list load triggered the cross-episode correlation fan-out on
every mount, so the page waited on up to 24 per-episode reads before it
painted. Move that work behind an explicit opt-in: the insights endpoint
takes an includeRecoveryGap query param (default off), the list reads the
count breakdown on a single fast query, and the recovery gap is computed
only when the viewer opens the Analyse expansion.
Tighten the typical-gap gate against coincidental data. A gap now counts
only from an episode that cleared a per-episode measurement floor
(MIN_GAP_MEASUREMENT_DAYS), at least MIN_EPISODES_FOR_TYPICAL_GAP such
episodes must qualify, and the median magnitude must reach
MIN_TYPICAL_GAP_MAGNITUDE_DAYS — a 0/+-1-day gap is the coincidental
baseline and is withheld as noise.
Add first-class qualitative lab findings (positive / negative / borderline
serology) alongside the existing numeric path. A LabResult is now EITHER a
numeric reading (value + unit, optional reference bounds) OR a qualitative one
(valueText, e.g. "negativ"), never both, never neither.
- schema: make `value` nullable, add `value_text`; migration 0181 is additive
(DROP NOT NULL + ADD COLUMN), every existing numeric row is untouched.
- validation: numeric-XOR-qualitative refine on create + update; unit/bounds
apply to the numeric path only; valueText capped at 120 chars. The single
resource PUT rejects a cross-type edit.
- serialise: carry valueText through both DTOs; a qualitative row reports the
neutral `unknown` range verdict (no number to classify).
- FHIR: a qualitative result emits valueCodeableConcept — SNOMED qualifier
value for confidently-known terms (Negative 260385009, Positive 10828004,
Not detected 260415000, Detected 260373001), text-only for borderline /
grenzwertig and any unrecognised term. The raw text always rides .text.
- UI: a numeric/qualitative toggle in the lab form; list, history, detail,
chart, sparkline, and the doctor-report PDF all render qualitative readings
as their text and never plot or divide on a null value.
- i18n: new labs.form keys across all six locales.
- openapi: response carries a nullable value + valueText; regenerated.
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.
A protected share link no longer renders the record until the passphrase
is verified. The public page checks the gate state first (without bumping
access counters), and for a link with a passphrase hash it serves a gate
island unless a valid, token-scoped unlock cookie is present. A legacy
link with a null passphrase hash renders exactly as before.
The unlock route verifies the submitted passphrase with a constant-time
compare against the stored hash, is rate-limited by share-unlock token
and IP before any compare, and on success sets a short-lived (30 min)
httpOnly, SameSite=Strict, Secure cookie scoped to that one token's view
path. Every failure class answers one blunt 401; no-store and the flat
404 for unknown links are preserved. The gate island auto-submits the
#k= fragment (scrubbing it from history first) or prompts for input.
Every new share link now carries a high-entropy passphrase (80-bit,
Crockford-base32, grouped XXXX-XXXX-XXXX-XXXX). The create response
returns the raw passphrase, the share URL, and a QR deep link EXACTLY
ONCE alongside the token; the server stores only the passphrase's HMAC
hash (the same key as the token hash). The QR deep link carries the
passphrase in the URL fragment (#k=) so it never reaches a server log,
referrer, or access record.
Add the passphrase generator, normaliser, and constant-time verifier;
the short-lived token-scoped unlock-cookie mint/verify; a gate-state
resolver that reports live + passphrase status without bumping access
counters; and the unlock request schema.
Centralise per-surface AI budgets and right-size status maxTokens; add
seed support (pinned for reference surfaces, seedless for the briefing);
force JSON on Ollama and Anthropic; reroll only the daily-briefing prose
once a day for variety while findings stay stable; reuse the corrective
retry on the comprehensive path; extract shared prompt contracts as one
source of truth for grounding, tone, and the GLP-1 safety rule; reserve
the coach budget atomically before the call and reconcile burned tokens;
turn the local-AI private-host flag into a host allowlist.
`ALLOW_LOCAL_AI_PRIVATE_HOSTS` was a binary flag that, when `true`,
opened every private/internal host at once — including the cloud
metadata endpoint and any internal panel. Replace the binary check at
all three sites (write-time validation, local client, test resolver)
with a shared `isLocalAiHostAllowed` helper: a comma-separated host list
permits only those exact hostnames, while the legacy `true` still
permits any private host for backward compatibility. The safeFetch /
isPublicUrl floor is untouched; the allowlist only widens what the
operator deliberately permits. Docs and the SSRF-pin inventory test are
updated accordingly.
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 /medications card and table render the dose-derived stock
(stockUnitsRemaining / stockDosesRemaining) straight from the
GET /api/medications list payload, which reads through cachedSwr on the
60s-fresh + 10-min-stale medications bucket. Registering, adjusting, or
deleting an inventory container changes that stock, but the inventory
routes never invalidated any cache — so the list served the pre-write
stock for the rest of the stale window. On the client the add / adjust /
delete supply mutations only invalidated the per-medication inventory
query, never the medications-list query that the card reads, so a mounted
list never refetched even once the server caught up.
Hard-evict the per-user medications + compliance buckets from every
supply-affecting write (inventory POST, the per-item PATCH / DELETE, and
the deprecated glp1 POST dose-change + ledger branches) so the next read
reflects the change rather than a stale SWR value. On the client,
centralise the supply mutations on a shared invalidateSupplyQueries helper
that drops both the medications-list key and the per-medication inventory
key. The card's neutral styling is unchanged.
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 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.
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.
Add POST /api/measurement-reminders/{id}/complete so a client can mark a
measurement reminder done on the server, rather than only dismissing the
notification locally. The route is the explicit user-action equivalent of
the cron auto-resolve: it routes through the one shared satisfaction
primitive, stamps lastSatisfiedAt, re-anchors the server-authoritative
nextDueAt, and fires no notification of its own.
Idempotent via the primitive's forward-only guard — completing an
already-completed or auto-satisfied reminder returns 200 with
completed=false so a repeat tap need not be special-cased. Owner-scoped;
a cross-user or tombstoned id 404s and never satisfies. No schema change:
lastSatisfiedAt already records the completion instant.
Extend the OpenAPI contract with the new path and the completion result
schema, and cover the route with unit tests (marks done, idempotent
no-op, owner-scoped 404, no double-notify).
Replace the per-page and per-chart disclaimer banners with a single
acknowledgment at the start of onboarding: HealthLog is a private tracking
tool, not a clinical assessment or diagnosis; talk to a doctor if worried.
- record the acknowledgment per user (disclaimer_acknowledged_at/_version,
migration 0175) mirroring the research-mode acknowledgment precedent
- gate the welcome "Get started" on the checkbox; expose the timestamp on
/api/auth/me so a returning user is never re-asked
- keep the full legal text reachable on the public privacy page
Add a discreet unread dot to the Coach FAB when the Coach has something
the user has not opened yet, and clear it when they open the Coach.
The signal is server-authoritative: a new coach_last_seen_at column on
users records the last time the Coach was opened, and the launcher's
status endpoint reports unread when the newest assistant message is
newer than that stamp — so the dot works even with no push channel and
clears across every device, web and iOS. Opening the Coach (FAB or the
/coach page) stamps the column via a new /api/insights/coach/seen
endpoint; the launcher keeps a local stamp only for an instant paint.
The dot is a calm cyan, not an alarming red, per the card-status rule.
Surface the population reference bands behind the metrics a Coach turn
carries as a compact, citation-aware grounding block appended after the
SNAPSHOT. For each present metric the block states the headline band, its
source (blood pressure on the ESH 2023 line, US/ESC framings as context
only), and where the user's value sits via the shared four-state
placement contract.
Framed strictly as general guidance: the block opens and closes with a
not-a-diagnosis caveat, never overrides the existing refusal/dose/drug-
level safety discipline, and carries no commercial brand name. Glucose
respects the diabetes opt-in — the tighter ADA management goal only when
the user has declared it, otherwise the general non-diabetic band.
The block is deterministic and inspectable: built purely from the
reference-range backbone over the same scalars the snapshot already
surfaces, so it can never cite a value or band the snapshot does not
carry.
Add absolute, guideline-backed safety floors that escalate a freshly logged
reading — but only after a second, confirming reading inside a one-hour
re-test window, so a single oscillometric spike or a one-off finger-stick can
never raise a false alarm:
- blood pressure 180/120 or higher (re-check, contact your doctor; symptom-
coupled lifts to emergency copy) and a symmetric low-systolic-under-90
cautionary tier;
- glucose under 70 (low) and under 54 (very low), and a sustained very-high
250-or-higher tier. The 200 DKA criterion deliberately never shows an
all-clear and never urgently escalates on its own, since a value alone
cannot rule euglycemic DKA in or out.
The escalation reuses the urgent SYSTEM_ALERT path with a 24h per-reason
dedup, never names a condition, and gates glucose behind the glucose module.
An optional transient `symptomsPresent` flag on the measurement write lifts a
confirmed breach from the contact-your-doctor copy to the emergency copy. The
measurement POST runs the check fire-and-forget so a notification failure
never fails the user's write.
Introduce an explicit, user-declared "I have diabetes / clinician glucose
targets" preference (`User.hasDiabetes`, migration 0174, defaulted false) plus
its GET/PATCH endpoint at `/api/auth/me/diabetes`. The flag selects which
glucose target band a reading is judged against; it is never inferred from a
value and never asserts a diagnosis. Mirrors the existing per-user-scalar
preference pattern: 60/min rate limit, Zod validation, audit-logged,
field-by-field write. OpenAPI regenerated for the new route.
Extend the in-house spotlight into a cross-page tour: 15 module stops,
each gated on its module, walking the app and teaching what each module
does and how it feeds the others. Auto-starts after the anamnesis,
resumes from onboarding_tour_progress_json, re-enters per-module via a
header trigger, and replays from one Settings card. Adds the tour
progress pref + migration 0173 and the onboarding tour checkpoint route.
# Conflicts:
# src/components/onboarding/DoneScreen.tsx
Add nullable onboarding_tour_progress_json to users (migration 0173),
a Zod-validated progress shape, and extend POST /api/onboarding/tour to
accept a mid-tour resume checkpoint and clear it on replay. Surface the
resume point on GET /api/auth/me and register the contract in OpenAPI so
the native client mirrors it.
