Polar and Oura response classifiers were byte-identical copies of the
status-driven verdict, the typed API error, and the invalid_grant probe.
Extract classifyHttpStatus, an IntegrationApiError base carrying the vendor
label, and a vendor-scoped isOAuthInvalidGrant into a shared module; Polar
and Oura now re-export under their existing names and types so call sites
and instanceof checks are unchanged.
Collapse the triplicated classifyXFailure mapping (Polar, Oura, Nightscout)
onto one toFailureKind helper. Behaviour is identical: same classifications,
same failure kinds, same error types.
Only the Nightscout sync queue was asserted in allQueues; the two OAuth-
wearable polls shipped alongside it carry the same v1.4.37 dead-queue risk.
Assert POLAR_SYNC_QUEUE and OURA_SYNC_QUEUE membership, cron, and handler
wiring so a future refactor can't silently drop one.
The entries URL carries the access token as ?token=<secret>; a SafeFetchError
embeds the full target URL in its message, and the sync feeds err.message into
recordSyncFailure, which the status endpoint returns as lastError. Strip token
and api-secret query values to =REDACTED before the message reaches the ledger,
so the secret can never surface in the status response.
buildExtras emits bpInTargetCount90 + bpInTargetSpanDays90, but the
registered extras schema (additionalProperties: false) omitted them, so a
strict iOS decoder would reject the dashboard snapshot. Declare both as
nullable integers to match the runtime shape and regenerate the spec.
Hard-coding isSpotEstimate: true mislabels a dense Nightscout CGM stream
(~288 readings/day) as a spot estimate and undersells the data in the
clinical panel and coach. Compute readings-per-day over the covered span
and treat the series as continuous below the spot caveat once it clears a
~hourly bar (24 readings/day); sparse spot fingersticks keep the caveat.
The panel only renders the spot-reading line when isSpotEstimate, and the
OpenAPI field relaxes from a literal-true to a boolean.
Move the low-stock trigger from a bare runway threshold to the larger of that
threshold and the reorder lead time plus one dose interval, so a weekly
medication is flagged before its last dose rather than after — early enough to
reorder. The change only moves the alert earlier; no one's threshold shrinks.
Surface concrete dates (runs out on, reorder by) and a running-low vs last-dose
state through the existing badge and channel, never the card colour. A reorder
lead time is configurable globally with a per-medication override, and the glp1
card flag now runs the same runway decision as the daily check instead of a
stale dose count.
The low-stock alert fired when the projected runway dropped below the
user threshold (default 7 days). For a sparse cadence — a weekly
injection's 7-day floor is barely one dose-interval — the warning landed
with about one dose left, too late to reorder before the supply ran out.
Add an optional per-medication reorder lead time plus a user-level
default (0–60 days, default 10) and widen the alert trigger to
max(lowStockRunwayDays, leadDays + cadenceIntervalDays), so the warning
lands before the last dose for any cadence. Because the trigger is a
max() over the user floor it never shrinks anyone's current threshold; a
daily med with no lead keeps its prior boundary.
The push body and the card notice surface concrete dates — supply runs
out around <date>, reorder by <date> — with a last-dose informational
state and the days/units fallback when supply data is thin. Retire the
stale fixed 4-dose count threshold on the GLP-1 details endpoint and
route its card lowStock flag through the same runway evaluation so the
card and the daily cron agree. Surface the lead default in the low-stock
settings card with progressive disclosure; a single medication can
override it.
Additive schema: nullable Medication.reorderLeadDays (migration 0161, no
backfill) and notificationPrefs.medication.reorderLeadDays. OpenAPI
regenerated.
Connect Polar and Oura through full OAuth, mirroring the existing wearable
house-pattern: a signed, expiring, provider-bound state doubles as an httpOnly
cookie, tokens are encrypted on the user, and an hourly job pulls sleep, heart
rate, respiratory and activity into canonical measurements under each source,
idempotently. Polar Nightly Recharge and Oura readiness feed the recovery
series, which now ranks WHOOP, then Oura, then Polar over the computed proxy.
Settings cards, localized copy and the credential env contract are wired for
both; the providers are optional and configured all-or-none.
Connect an Oura account over the Cloud v2 API: an authorization-code OAuth
flow (shared app from OURA_CLIENT_ID / OURA_CLIENT_SECRET) on the same signed
state machinery as Polar. Unlike Polar, Oura issues refresh tokens; the sync
refreshes reactively on a 401, rotating and re-encrypting both tokens, and a
403 stays a hard reauth rather than a refresh.
An hourly poll-cohort job maps daily readiness to RECOVERY_SCORE, sleep to
per-stage durations plus efficiency / HRV / resting heart rate / respiratory
rate, and daily activity to steps and active energy — all tagged source OURA,
idempotent on (userId, type, source, externalId). Readiness flows through the
canonical recovery ladder above the computed proxy. Settings gains a connect /
disconnect card. Tokens are never logged or returned; every egress goes
through safeFetch.
Connect a Polar account over AccessLink v3: an authorization-code OAuth
flow (shared app from POLAR_CLIENT_ID / POLAR_CLIENT_SECRET) backed by a
stateless HMAC-signed state token doubling as an httpOnly cookie for CSRF.
The callback verifies the signature, expiry, provider binding, and the
byte-exact cookie match, then encrypts the access token plus member id onto
the user row.
An hourly poll-cohort job maps Nightly Recharge recovery, sleep stages,
and daily activity to canonical measurements tagged source POLAR, idempotent
on (userId, type, source, externalId). The recovery band feeds RECOVERY_SCORE
through the canonical ladder, which now ranks native readiness above the
computed proxy. Settings gains a connect / disconnect card. Tokens are never
logged or returned; every egress goes through safeFetch.
Emit invite links as a /invite/<token> path the iOS app intercepts as a
universal link to start a prefilled registration, with a browser fallback that
redirects to the register flow once the token shape checks out. The path is a
thin, side-effect-free redirect — no lookup, no logging, no enumeration oracle
— and carries the same no-store, no-index, no-referrer hardening as the other
secret-bearing path since the token rides in the URL.
Surface the server-authoritative sleep-rhythm read in the coach snapshot
so a reply can reference cumulative sleep debt and the chronotype band the
Sleep page and dashboard already show. The values come from the same
assembler those surfaces use over a fixed trailing-42-day window, never a
recompute, so the coach can only quote what the page renders.
Hold the learning gate: the chronotype band and social jetlag are emitted
only once the signal is ready; a calibrating chronotype is surfaced as such
and never asserted as a band. Document the new fields and minute units in
the system prompt.
Encode the admin invite QR as a clean /invite/<hlv_token> universal-link
that the iOS app intercepts via the AASA wildcard matcher. Add the
matching web route as a thin, shape-validated redirect onto the existing
register flow, and open the path on the public allowlist so an
unauthenticated scanner reaches it. A malformed token segment is
indistinguishable from no invite — no database hit, no enumeration
oracle. The token is never logged.
Surface a clinical panel beneath the blood-glucose chart: time-in-range on the
consensus bands, the glucose management indicator and estimated A1C, and the
coefficient of variation with its instability flag by default, and the J-index
and the low and high blood-glucose risk indices with a per-context breakdown
behind an advanced disclosure. Below the calibration threshold it shows a calm
learning state, and it always carries the spot-reading caveat. The analytics
read, the dashboard snapshot, the coach and the doctor report all consume one
computed result over a fixed window, so the panel, the assistant and the
printed report cannot disagree.
Assemble a sleep-rhythm read on the canonical per-night reconstruction — the
same midpoints and asleep totals the sleep score uses — that reports a rolling
sleep debt against the age-based need and an MCTQ chronotype with its mid-sleep,
social jetlag and band. A shared assembler caps the chronotype window so the
dashboard and the dedicated read return identical values, and both withhold a
confident reading behind a learning state until enough nights accrue. The sleep
page gains a debt headline and a chronotype card with the deeper detail behind
an advanced disclosure; the sleep score is left untouched so debt reframes the
sufficiency gap without double-counting it.
Make computeSleepRhythmFromNights own the chronotype look-back so the dashboard
summary (a year of nights) and GET /api/sleep/rhythm (six weeks) return the
same band, mid-sleep, and social-jetlag values rather than averaging different
samples. Derive the free/work day-type from the local wake-day digits so the
classification holds in far-east timezones, and read the shared sleep-rhythm
DTO type into the client hook instead of a hand-mirrored copy.
Route the sync write through mapSgvEntryToMeasurement so the
entry-to-measurement shape has one source of truth instead of an
inline copy plus an unused parallel mapper that could drift.
Pull continuous glucose readings from a self-hosted Nightscout instance
and store them as immutable BLOOD_GLUCOSE mg/dL measurements
(source=NIGHTSCOUT), giving the glucose panel real CGM density.
- client over safeFetch: public-host pin by default, relaxed only on the
per-user private-network opt-in; redirect pinned manual + timeout
- credentials encrypted at rest on User; URL is the connect marker
- sync maps SGV entries first-write-wins on (userId,type,source,externalId)
- connect/disconnect/status routes: apiHandler + requireAuth + rate limit;
connect validates by a live test fetch with clear errors
- hourly poll-cohort job registered in the all-queues registry
- settings card with URL, token, and the private-network toggle
- i18n across all six locales
Compute cumulative sleep debt and the MCTQ chronotype server-side off the
canonical night reconstruction the Sleep Score reads, and render them on
the sleep page: a sleep-debt headline with a calm partial state under the
night threshold, and a chronotype card whose social-jetlag detail and
corrected mid-sleep sit behind an advanced disclosure. Both hold a learning
state on thin data and never assert a total or a band.
Serve the same values to the dashboard summary and a new GET /api/sleep/rhythm
read so the native client renders identical figures. Free vs work nights
default to weekend in the user's timezone until day-type tracking exists.
Extend MeasurementSource with NIGHTSCOUT, POLAR, OURA and add the
per-user encrypted credential columns each source needs: a Nightscout
base URL + token plus a private-host opt-in flag, and Polar/Oura OAuth
tokens mirroring the WHOOP columns. Migration 0160 is additive only —
new enum values, nullable columns, one boolean default false.
Register the three sources across the read enum, the integration-status
key set, and the source-priority ladders.
Compose two pure, server-authoritative modules on the canonical per-night
reconstruction rather than a second pass: a rolling sleep-debt that sums each
night's deficit against the existing sleep need, drains as nights age out, and
never mints negative debt; and an MCTQ chronotype from free-day mid-sleep with
the sleep-debt correction and the social-jetlag gap, classified into a band
through the shared estimator. Both withhold a confident reading behind a
learning gate until enough nights accrue.
Pass the report's timezone into the canonical recovery resolution so the PDF
buckets a WHOOP-native row and its computed proxy onto the same physiological
night — the proxy is stamped the day that ended while WHOOP stamps the wake
morning — instead of a raw calendar day. Aligns the printed recovery summary
with the tile, the coach, and the companion feed.
WHOOP stamps a recovery on the wake morning while the computed proxy files the
same night under the day that ended, a systematic off-by-one that left both
rows alive as two competing recovery days once the native series was read.
Resolve recovery by a source-aware wake-day key in the user's timezone — the
computed proxy's day is shifted forward to meet WHOOP's wake morning — so one
night collapses to one canonical row without re-dating the stored stamp and
without a backfill. Thread the same resolution through the wellness reader, the
coach nudge trend, and the coach snapshot, which had each read recovery raw.
The native WHOOP recovery and the computed proxy stamp the same night on
opposite clocks: WHOOP files the wake-morning instant (day D), the proxy files
noon-UTC of the day that ended (day D-1). Bucketing raw measuredAt by calendar
day leaves both alive as two competing recovery days.
Bucket each source by the user's local wake-day instead — shifting the proxy's
day-that-ended stamp forward one day to meet WHOOP's wake-morning stamp — so a
single night collapses to one canonical row while distinct nights stay
separate. Resolve the coach-nudge recovery trend and the coach-snapshot dedup
through the same path so no surface blends the two series or drops a genuine
native value on a numeric tie.
Convert the glucose figures the coach snapshot builds to the user's unit and
carry the unit into the prompt, so the coach speaks mmol/L to a mmol/L user
instead of a bare mg/dL number — the one glucose surface the unit work had not
reached. Aggregate the series stats over raw values and convert each figure
once, matching the detail page and the FHIR export so a multi-reading mean no
longer differs in the last decimal between surfaces. Drop the fixed day count
from the median label, which the windowed median value cannot honour.
Add OpenAPI registry entries for the two endpoints the iOS client now depends
on — the measurement series read it charts from and the provider endpoint it
gates coach visibility on — so the contract source of truth covers their
response shapes and CI catches a future drift. Give the consent active-receipt
dedup a deterministic id tie-break so the unique-index build cannot abort on an
identical-timestamp pair, and map a concurrent first-grant unique violation in
createReceipt to the winning receipt instead of a 500.
Document GET /api/measurements/series and GET /api/user/ai-provider in the
OpenAPI registry — both are consumed by the iOS client (charts and Coach
visibility gating) but were absent from the spec.
Break migration 0159's active-receipt dedup on (created_at, id) so an exact
created_at tie still leaves one survivor, keeping the unique index build from
aborting 23505 on affected tenants.
Catch P2002 in createReceipt: two concurrent first grants both reach create,
the loser re-reads the winning active receipt and returns it instead of a 500.
Nights with AWAKE rows but no IN_BED row (a common Apple Health shape)
lost their efficiency sub-score after the canonical reconstructSleepNights
migration, silently reweighting the composite and shifting historical Sleep
Scores. Restore the synthesised asleep + awake fallback on top of the deduped
per-night totals: keep the real IN_BED figure when present, synthesise when
only asleep + awake exist, stay null when neither.
Mint the web AI-consent receipt inside a serializable transaction with an
in-transaction recheck, backed by a partial unique index over one active
receipt per user and kind, so two concurrent mounts can no longer leave two
active grants; a duplicate maps to a no-op mint. Supersede an active row
against the server clock rather than the client-supplied timestamp so a
backdated grant cannot invert the audit chain, and revoke through a single
atomic update. Rate-limit the consent endpoints per user. Extract the
hand-rolled sub-page back link into one component and adopt it across the
four pages that duplicated it.
Two follow-ups to the active-receipt uniqueness work:
- Migration 0159 now revokes all-but-the-newest active row per
(user_id, kind) before building the partial unique index. Without the
pre-flight dedup the CREATE UNIQUE INDEX would abort on any tenant that
already carries duplicate active grants — exactly the tenants the fix
targets — and fail the deploy.
- createReceipt stamps the superseded row's revoked_at with a server
clock instead of the client-supplied signedAt. A backdated signedAt
would otherwise mark the prior row revoked before its own signed_at,
inverting the audit chain. The new row keeps the client signedAt.
Give each WHOOP collection its own incremental cursor in a resource_cursors
map so a slow or rejecting collection no longer drags the sync window forward
for its siblings; legacy connections fall back to the shared last-synced
timestamp. The update webhook now carries the record id and triggers a
targeted single-record refresh instead of re-walking the collection, and a
full sync anchors at a fixed deep start so a backfill covers the span an
incremental tick skips. Cursor advances are a single atomic update guarded by
GREATEST so the independent resource queues cannot race each other backward.
Ingest row shape, source tagging, and upsert keys are unchanged.
Route the derived Sleep Score through the canonical night reconstruction
instead of its own UTC-day grouping, so a night logged by more than one
source is deduplicated to a single writer rather than summed. The score and
the readiness that folds it now read true per-night totals; multi-source
nights drop to their real figure. Emitted minutes and the night stage map
round to integers.
Resolve recovery to one canonical series — WHOOP-native when present, the
computed proxy as fallback — in the wellness reader, the doctor report, and
the coach snapshot, and stop presenting the proxy and the native score as two
numbers. A WHOOP-connected account's recovery now reads the native value on
the tile, the chart, and the printed report alike.
The four WHOOP resources are independent pg-boss queues that run concurrently
for the same user, so the read-modify-write that merged one cursor key into the
map and wrote it back could let a sibling's write clobber a just-advanced
cursor. Replace it with a single jsonb_set UPDATE that merges in place under the
row lock, and GREATEST so the shared last-synced instant only moves forward.
The resource key is parameter-bound and asserted against the closed resource set
before it reaches the JSON path.
RECOVERY_SCORE is written by two sources for the same day: the WHOOP-native
percentage from the device sync and the COMPUTED proxy from the nightly
readiness job. The wellness reader hard-filtered to source COMPUTED, silently
dropping every ingested native row, and the doctor PDF blended both sources
into one min/avg/max. The COMPUTED proxy also equals the readiness blend
verbatim, so the Coach prompt carried the same number under both READINESS and
RECOVERY_SCORE.
Add resolveCanonicalRecovery: per day, keep the WHOOP row when present, else
the COMPUTED proxy. Drop the COMPUTED-only filter for RECOVERY in the wellness
reader and resolve to the canonical row; STRESS and STRAIN stay COMPUTED-only.
Resolve the doctor PDF wellness summary the same way so the report reads the
native value, not a proxy/native blend. Dedup the Coach snapshot: omit the
recovery line when it mirrors readiness (the no-native case), keep it when a
WHOOP-native value differs. Document the WHOOP-over-COMPUTED resolution on the
sync delta feed, which already mirrors each row with its source so the client
resolves one canonical series rather than charting two.
A WHOOP-connected user's recovery tile, chart, and PDF flip from the proxy to
the native value.
Glucose stays stored canonical mg/dL; conversion now happens at the
serialization boundary through the one convertGlucose/resolveGlucoseUnit
helper rather than ad hoc at render time. The series DTO reports the user's
unit and converts its points and stats; the CSV export converts and emits a
unit column to match the FHIR export; the blood-glucose page and stat strip
honour the preference; the median label declares its trailing-90-day window.
A mmol/L user now reads the same converted value on every surface and in
both exports instead of a mg/dL CSV against a converted FHIR document.
POST /api/consent/ai, POST /api/consent/ai/web, and GET/DELETE
/api/consent/ai/latest had no rate limit, so a scripted loop or a
stolen session could pin the receipts table. Add a shared per-user
bucket (20/min, keyed by user id) mirroring the coach-chat ceiling,
checked right after requireAuth, returning 429 with the X-RateLimit
headers attached. The web heal endpoint runs on every AI-settings
mount, so the bucket is generous enough to never throttle normal use.
Two concurrent web-grant heals could each pass the read-then-create gap
and insert a duplicate active ai_full receipt; the revoke path then had
to chase one row at a time. Wrap the web-grant mint in a Serializable
transaction with an in-transaction re-check, and add migration 0159 — a
partial unique index over (user_id, kind) WHERE revoked_at IS NULL — as
the structural backstop. createReceipt now supersedes any active row of
the same kind before appending, and revokeLatest flips revoked_at via a
single atomic updateMany, so the append-only audit chain is preserved
while at most one active row ever exists.
Replace the single shared last-synced cursor with a per-resource cursor map
on the WHOOP connection. Recovery, sleep, workout, and cycle each advance only
their own cursor on a successful fetch+upsert, so a slow or 403-ing collection
never drags the incremental window forward for its siblings and its own
late-arriving records stay inside the overlap. Legacy connections fall back to
the shared last-synced instant, so no historical state is lost.
Add single-record fetch-by-id client routes and per-resource by-id syncs. The
update webhook now carries the resource id through the queue payload, so the
worker resolves and upserts that one record immediately rather than re-walking
the whole collection on the next overlap tick.
Anchor a full sync at a fixed deep-history point instead of returning no lower
bound, so a backfill covers the multi-year span an incremental tick would skip
and a stale cursor cannot silently narrow it.
Glucose is stored canonical mg/dL but the series DTO, CSV export, and detail
page emitted raw mg/dL while FHIR already converted to the user preference.
Convert at serialization through the single convertGlucose helper:
- series route sets unit from the user's glucoseUnit and converts each point
- CSV export converts BLOOD_GLUCOSE rows and emits the unit in the unit column
- the detail page + stat strip honour the preference via the chart value scale
- declare the trailing-90-day window in the glucose median label across locales
mmol/L-preference users now see the blood-glucose page, stat strip, iOS series,
and CSV in mmol/L; mg/dL users are unchanged.
Replace the divergent UTC-day night reconstructor in the Sleep Score with a
thin adapter over reconstructSleepNights, the shared engine the dashboard,
hypnogram, and doctor surfaces already read. The old path bucketed rows by UTC
calendar day and never deduplicated writers, so a multi-source night (WHOOP +
Apple Health for the same sleep) summed both writers and roughly doubled the
total. The adapter inherits session-clustering, local-wake-day keying, and
multi-source writer dedup, then derives the score-only fields the canonical
night does not carry: REM and Deep minutes from the stage map, the stage-
breakdown flag from any granular stage, and the midpoint from the asleep span.
Select source and deviceType in the Sleep Score read so the writer-dedup
ladder fires, and thread the user source priority through so the chosen writer
matches every other sleep surface. Round emitted asleep and in-bed minutes to
whole numbers, and round the per-stage map in the sleep-night DTO, matching the
integer contract the native client decodes.
A multi-source user's sleep score and the readiness score that folds it drop
once the double-count is removed, reflecting the true single-writer night.
