Marc-André Bombeck f4dec8c28f feat(medications): fractional dosing via decimal units per dose (#316)
A dose can now consume a fraction of a unit — a half, third or quarter
tablet for a split pill. The wizard offers a curated fraction set beside
the whole numbers (the most error-resistant input); units-per-dose and the
per-container counts widen from Int to Decimal, so a 30-tablet pack dosed
at a half reads 29.5 after one dose and the days-left projection follows.
The consumption ledger stamps and refunds the exact fraction, and existing
whole-number doses are untouched. OpenAPI regenerated — the three unit
fields move from integer to number — and the units-per-dose hint is
updated across the six locales.

Also anchors a first-use date relative to now in an inventory route test
that had aged past its 30-day in-use window.

Marc-André Bombeck 6fef2081d0 fix(medications): the audit findings on the new supply and dose surfaces
- The escalated card row keeps its time anchor: the red badge carries
  the matched window or the overdue-slot value beside it, and the
  inline row's range stays visible on mobile, where it was the only
  clock on the card.
- Take-all-due collects what the cards offer: a dose escalated past its
  catch-up band joins the set with exactly the slot the card's own
  button would record; as-needed medications never join.
- The table's stock warning follows the user's runway threshold instead
  of a leftover four-dose constant; threshold off means no amber, empty
  stays red.
- The card itself shows the remaining runway in the warning tone once
  it crosses the threshold — only then, the card stays calm above.
- The low-stock push deep-links straight into the supply tab and its
  APNs payload keeps url, runwayDays and thresholdDays; supply tab and
  threshold setting link to each other; the reminder-thresholds and
  notification-prefs endpoints enter the OpenAPI contract.

Marc-André Bombeck 3943dcfb72 feat(medications): as-needed medications log without a schedule
A medication can declare itself as-needed: no schedules, never due,
never reminded, excluded from every compliance rate — but intakes log
ad-hoc, consume inventory exactly like scheduled doses, and the
history stays. The wizard offers it as a cadence choice and round-
trips it on edit; card, table and detail show a calm marker where the
next dose normally sits, the take-all dialog never collects one, and
the supply runway stays unknowable by construction. (#316)

Marc-André Bombeck cac9a32756 feat(medications): low-stock notifications with a runway threshold
A daily job projects each tracked medication's remaining supply against
its schedules and notifies through the normal channel cascade when the
runway falls below the user's threshold (default seven days, 1-60 or
off, set beside the reminder thresholds). One notification per
crossing: a stamp on the medication row re-arms on refill or threshold
change, and a failed dispatch leaves it clear for the next day's retry.
The GLP-1 card's fixed four-dose flag stays as the locked iOS read
contract; the engine covers it like any other medication.

Marc-André Bombeck ea29e9cf1b feat(dashboard): open the day with a verdict
The dashboard now leads with a daily band: the greeting, the one item
that matters right now — an overdue or upcoming dose, a very high
blood-pressure reading, weight drifting from its range, a run of short
nights, a quiet stretch, a score drop, or the briefing's key finding —
with a single action, today's dose tally beside the next due time, and
the health score as a ring on the right. The verdict resolves from a
fixed nine-rung ladder on the client with the thresholds shared from
the nudge engine through a dependency-free module, the blood-pressure
rung uses fixed crisis floors rather than personal target ranges, and
a cached next-due in the past never renders as overdue. The band
reserves its exact footprint from the first paint, swaps in with the
tiles in one pass, respects the hour-format preference, and can be
turned off in the dashboard settings; the greeting moves out of the
page header into the band.

Marc-André Bombeck f790e14edd fix(api,lib): consent before reuse, tighter inputs and caches that tell on themselves
Per-status texts check AI consent before the unchanged-data refresh can
re-stamp them, the comprehensive fingerprint folds in the comparison
baseline and generation language so toggling either regenerates once,
and profile, threshold and source-priority writes evict the analytics,
targets and derived caches they feed. CSV export neutralises spreadsheet
formula prefixes on free-text cells while numeric columns stay typed,
the derived batch validates its type token against the measurement enum
and carries a per-user rate limit, and a dose synced from the phone app
counts as the interactive write it is. Background cache refresh
failures log a structured event instead of vanishing, the warm queue
runs visit-triggered jobs alongside the nightly walk, the formatter
memo evicts one entry instead of flushing wholesale with its option
objects frozen, the targets cold build bounds its fan-out, and time in
bed unions every writer's envelope while stages stay with the richest
recorder.

Marc-André Bombeck 23f7c74c04 perf(insights): regenerate texts only when the underlying data changed
A sha256 fingerprint of the compacted feature snapshot is stored beside
every generated text; nightly, forced and ingest-triggered regeneration
all skip the model call when the fingerprint matches and refresh the
timestamp instead. Warms cover only the user's resolved locale and the
blanket per-status eviction after a comprehensive generation is gone —
a lazily-read second locale regenerates on its own miss path. The
ingest debounce widens from thirty minutes to six hours and no longer
deletes cache rows, the visit-triggered warm re-checks freshness at job
start, backs off for an hour after a failure and is capped at two
forced runs per user per day, and its dedup window now outlives the
client poll horizon. An active day drops from hundreds of model calls
to a handful tied to actual data change.

Marc-André Bombeck 03453aaed2 fix(insights,cache): surface revalidation to clients and evict on interactive writes
Stale-served insights responses now carry a revalidating flag; the
advisor and comprehensive queries poll on a bounded 25 s cadence until
the background warm lands, so an open session converges instead of
pinning yesterday's briefing for an hour. Interactive measurement
writes (single create, edit, delete, bulk-delete, restore) hard-evict
the analytics cache so a manually entered value is reflected on the
next read; background batch sync keeps the mark-stale path. The
visit-triggered force warm collapses to one job per user instead of
one per locale, and the umami script proxy failure now annotates a
named action with the failure reason instead of a bare flag.
2026-06-11 19:45:32 +02:00
Marc-André Bombeck 78fe82e348 perf(insights,api): always answer instantly and regenerate in the background
The insights read path served a cold cache by generating inline — up to
ten seconds on first visit — and the nightly warm pass structurally
excluded evening visitors: their visit stamped the cache, the half-four
run skipped it as fresh, and it expired exactly at the next evening's
visit. Stale content now serves immediately with its timestamp while
one background job revalidates, the warm threshold drops to an hour,
forced warming fills both message locales, the analytics caches serve
stale-while-revalidate, the profile endpoint parallelises its reads,
the bug-report status drops a write per call, the umami proxy degrades
to a no-op script instead of an error, the insights route sheds its
heaviest static imports, and the medication page prefetches on intent.

Marc-André Bombeck a62e00cfcd feat(coach): a guided dialog for follow-ups and nudges that know their owner
Open follow-up questions now run as a guided in-chat sequence — a quiet
card offers to start, the coach asks one question at a time with
visible progress, answers can be adopted into the matching self-context
field, skipping keeps a question pending and a closing summary says
what was taken over. Proactive nudges learn three new deterministic
signals — weight drifting from its target band, a run of short nights,
an active user falling silent — address the focus the user asked to
watch, and gain per-group toggles and a frequency preference.

Marc-André Bombeck 9445d89b76 refactor(api,tz): one typed client for every call and one home for wall-clock math
A typed apiFetch wrapper owns the envelope unwrap, the ok-check and the
error read for every client call — two hundred call sites across the
app migrate onto it and a lint rule keeps raw api fetches out for good.
The legacy timezone helpers fold into the tz module and test fixtures
drop personal names.

Marc-André Bombeck 410c62c292 refactor(jobs,dashboard): a thin worker registry and a composed dashboard

behaviour, pinned by the existing suites.

Marc-André Bombeck b55fab5e94 fix(insights,coach): warm every card nightly and round out the smaller findings
The pregenerate pass now warms the status cards even when the
comprehensive step is budget-blocked, failed or timed out — the gap
that left cards generating on first visit despite the nightly runs —
and the loop gains a per-user timeout so one hanging provider cannot
stall the tick. Schedule edits recompute their rollup days immediately,
the compliance cache keys on the timezone, open doses no longer count
against the nudge trigger, an invite sent against an open registration
still lands in the ledger, the self-report prompt fence uses explicit
data markers, the maintenance crons invalidate the caches they touch,
and a flaky audit assertion polls instead of racing. Six care-focused
achievements join the engine: miss-free streaks, measurement routine,
a complete self-context and a sleep-log run.

Marc-André Bombeck 5b75184649 feat(coach,admin): finish the self-context and invite surfaces end to end
Invites move into their own admin section with a real ledger: status
badges, expiry, uses, a redemption history of who joined when (new
redemption table, revocation is now soft so history survives), and an
honest one-time link/QR moment. The assistant self-context grows
structured fields for conditions, allergies and focus — encrypted like
the free text — merges age and gender from the profile into one fenced
prompt block, and asks up to three targeted follow-up questions that
surface as tappable chips above the coach composer. A fourth nudge
trigger gently suggests a check-up when the self-context is stale and
the coach is actually in use.
2026-06-10 16:18:48 +02:00
Marc-André Bombeck 51dd614199 feat(coach,auth): self-context for the assistant, invite links, proactive nudges
Users can now tell the assistant about themselves in an encrypted
free-text profile that feeds the coach and briefing prompts as clearly
fenced context, with the coach allowed one targeted follow-up question
when the picture is incomplete. Operators on closed registrations can
mint expiring invite links with a QR code from the admin area; a valid
invite opens registration exactly as many times as it allows and records
who redeemed it. A nightly pass watches three deterministic signals —
low adherence, blood pressure above its target band, a falling recovery
trend — and sends at most one coach nudge per week through the existing
notification channels, gated behind the same opt-outs as every other
assistant surface.
2026-06-10 15:40:48 +02:00
Marc-André Bombeck 3cf48fa0f1 fix(insights): honest assistant pipeline — gates, tombstones, retries, truthful states
The two-o'clock status crons generated for every account, ignoring both
the per-user coach opt-out and the operator kill switch; they now share
one gated discovery that also skips users the pregenerate pass will
rewarm anyway, and the mood card finally gets the nightly run the other
six always had. Deleted measurements no longer feed any prompt. Locales
without an assistant language fall back to English consistently instead
of German texts with English fallbacks. A rate-limited regenerate stops
claiming success, the dashboard briefing state distinguishes a missing
provider from a pending generation and serves a stale briefing with its
timestamp instead of hiding it, narrative warming actually processes
oldest first, and worker failures reach the error tracker through one
shared reporter while the insight queues gain real retries.

Marc-André Bombeck 0a4bf34a2b fix(medications): align the slot lifecycle with the band model end to end
The auto-miss cron stamped every pending row missed a flat day after
its slot even though weekly schedules stay takeable for days, touched
tombstones because it never filtered deleted rows, and a verdict stuck
even after the dose was taken. The cron now derives its cutoff from the
schedule's window reach, skips deleted rows and bumps the sync counter,
and a take clears the auto-miss flag. Editing a schedule tombstones the
open pending rows of the old anchors and reconciles a stale window onto
the new times. The bulk write path attributes takes through the same
band engine as the single-intake routes and accepts forceSlotInstant
per entry. Configured dose windows now reach every compliance call site
through one shared schedule select, and the card window pill takes a
timezone, treats a degenerate window as a point and counts dose times
instead of schedule rows.

Marc-André Bombeck 9e6d0d5acb fix(medications): converge intake writes onto existing slot rows across sources
A take whose slot the legacy resolver rejected fell back to a standalone
insert that kept the client's scheduledFor, parking a second live row on
an anchor the reminder projector had already minted — the partial unique
index permits that because it spans source. Both intake write routes now
probe the slot source-agnostically and converge onto the existing row
before inserting, and a standalone insert anchors on the take time per
the ad-hoc contract. The compliance rollup counts distinct slots instead
of rows, which also corrects historical duplicates on the next recompute,
and the slot dedup pass runs nightly instead of only at worker boot.

Marc-André Bombeck b8c2b2e8c5 fix(measurements): keep the mean-consolidation pass alive past unique collisions
The nightly mean-consolidation upsert targets the externalId arbiter, but
the measurement table carries a second full unique on (user, type,
measured_at, source, sleep_stage) that also spans tombstones. Any row
parked exactly on the canonical local-noon instant made the insert throw
P2002, and because the global pass had no per-bucket fence the first
poisoned day aborted consolidation for every remaining user and type.

writeDay now probes the canonical slot inside the transaction and
resolves the collision deterministically: rows the pass owns (tombstones,
per-sample rows about to fold) shift to the next free second, foreign
live rows keep their instant and the mean row yields instead. The runner
gains an optional per-bucket error fence so one bad day is logged,
counted as daysFailed, and skipped.

Marc-André Bombeck 29fa982e11 fix(medications): count forgotten doses as missed, not skipped
A never-acted dose past its 24h cutoff was flipped to skipped=true by the
hourly cron. The compliance engine excludes skipped doses from the
denominator (a deliberate user pause), so a forgotten dose then counted
neither as taken nor missed — silently inflating adherence.

Add a dedicated auto_missed terminal state. The cron now sets auto_missed
(not skipped) on a never-acted pending row, so the engine counts it as a
real miss against the rate, while a user-initiated skip stays excluded.
The two are mutually exclusive on a live row by construction.

Marc-André Bombeck 93d47ddd05 feat(cycle): fertile-window reminder for the conception goal
Add a CYCLE_FERTILE_SOON reminder that fires two days before the
predicted fertile-window start. Twice-gated and default-OFF: it only
surfaces when CycleProfile.goal is TRYING_TO_CONCEIVE and fertileWindowStart
is populated, so fertile language never reaches the avoid / general / peri
goals. Reuses the existing cycle-reminder cron, discreet mode, clientManaged
suppression, idempotency ledger, and push-attempts plumbing verbatim; the
body carries the non-medical, not-a-contraceptive framing.

Marc-André BombeckandClaude Opus 4.8 824dcbb01a perf(cycle): scope the reminder cron to the in-window cohort and harden the period write
Push the cycle-reminder cron's gating into the query instead of loading
every CyclePrediction row each tick: filter on the user's
cycleTrackingEnabled / predictionEnabled relation and restrict to rows
whose nextPeriodStart falls inside a tz-generous [today-grace, today+lead]
string window. The per-tick cost now scales with the in-window cohort, not
the whole table; the exact per-user-timezone window still runs in JS.

Make the period-boundary shortcut transactional and idempotent: wrap the
close-prior + open-new (or stamp-current) cycle mutations in a single
$transaction so two concurrent taps cannot double-close a prior cycle or
compute a length against a stale read, and add withIdempotency so an exact
key replay is a no-op. The boundary day-log now ranks the incoming flow
against any existing same-day entry and never downgrades a richer flow.

Decode sync cursors additively: a live beta v1 token keeps its
measurement / mood / intake watermarks and simply fresh-scans the two
domains added in v2 (cycleDays, cycles) rather than forcing a full
re-init. Correct the stale "no live consumer" comment.

Thread the user's timezone through the Coach cycle snapshot so "today",
day-of-cycle and days-until-period derive from the user's zone — matching
the calendar and insights routes — instead of wall-clock Berlin.

Marc-André BombeckandClaude Opus 4.8 ac13dd28ed fix(cycle): honour the sensitive-data encryption toggle + harden the write path
- When the sensitive-category encryption preference is on (the default),
  encrypt the intent-revealing day-log fields (sexual activity, protection,
  pregnancy/progesterone tests, contraception) into an encrypted envelope and
  leave the queryable columns null, decrypting on read. The toggle now does
  what it says rather than storing those fields in plaintext.
- Make the day-log write a partial merge so a re-log only overwrites the
  fields it carries, never nulling untouched ones (no more data loss when the
  same day is logged again).
- Make the upsert collision-safe: a manual entry and an imported entry on the
  same date adopt one canonical row instead of throwing, and the single POST
  returns a clean conflict rather than a 500; one bad date no longer aborts a
  whole import.
- Compare the decrypted note, not the ciphertext, so an unchanged re-log is a
  true no-op and stops needless re-sync.
- Hoist cycle attribution out of the per-entry loop; map bulk failures to
  stable reason codes; audit the import goal change; mask the event name in
  discreet reminder pushes; add a one-tap hard-delete purge for all cycle data.

Marc-André BombeckandClaude Opus 4.8 e984ada5f1 feat(cycle): import Apple Health reproductive data into cycle, add cycle export
Promote the reproductive HealthKit category types out of the
Apple-Health-import privacy-hold list and route them into cycle day-logs
instead of measurements, and surface cycle data on the three export
surfaces.

Import promotion:
- A new HealthKit -> cycle mapping module is the single source of truth for
  how MenstrualFlow, IntermenstrualBleeding, CervicalMucusQuality,
  OvulationTestResult, SexualActivity, PregnancyTestResult,
  ProgesteroneTestResult, Contraceptive and the symptom category types fold
  into CycleDayLog fields / seeded symptom keys. The XML importer
  accumulates same-day reproductive samples and writes one canonical
  day-log per day with source APPLE_HEALTH and a synthetic per-day
  externalId for idempotent re-import. The fold is gated on cycle tracking
  being enabled, so a non-cycle export never provisions cycle rows. A
  contraceptive method nudges the profile goal toward avoiding pregnancy
  only when the goal is still on its default. Basal body temperature stays
  a measurement and mirrors onto the day-log. Pregnancy/Lactation status
  and the pregnancy-bleeding types stay deferred; the cycle awareness types
  remain server-derived.

Export:
- FHIR emits LMP (LOINC 8665-2), average cycle length (64700-8), period
  length (64698-4) and the current phase as opt-in reproductive-health
  observations grouped into their own document section.
- The doctor PDF gains an opt-in cycle section (recent cycles, average
  length and variability, current phase), privacy-default off like mood.
- The full-backup export, the weekly backup worker and the off-host DR
  snapshot include the cycle tables, and the admin restore re-creates them;
  the day-log note round-trips as ciphertext and is never decrypted onto a
  report surface.

Mapping table documented in docs/api/cycle-healthkit-mapping.md. Adds unit
+ integration coverage for the mapping, the import routing, the FHIR
observations and the backup round-trip. OpenAPI regenerated. Six-locale
strings added.

Marc-André BombeckandClaude Opus 4.8 6fdbb8d889 feat(cycle): predicted-period notifications + reproductive-data privacy docs
Add two cycle reminders through the existing notification cascade and the
honest self-hosting privacy framing for reproductive-health data.

Notifications:
- New event types CYCLE_PERIOD_SOON (fires ~2 days before the predicted
  next-period start, from the cached prediction) and CYCLE_PERIOD_CONFIRM
  (a gentle "did your period start?" on/after the predicted start while no
  period is logged, within a short grace window). Both default OFF and are
  gated again on cycleTrackingEnabled — opt in twice for a sensitive surface.
- A 15-minute pg-boss cron mirrors the mood-reminder worker: it scans users
  with cycle tracking enabled + predictionEnabled, computes who is in-window
  from the cached forecast, and dispatches one push per event per local day.
  Idempotency anchors on the push_attempts ledger (no new table). The queue
  is declared, registered in allQueues, scheduled, and wired to a boss.work
  handler, with a source-grep guard so it cannot ship unregistered.
- Honours notificationPrefs.cycle.clientManaged (skip the server push when
  the device owns local reminders, with a suppressed annotation, mirroring
  the medication path) and CycleProfile.discreetNotifications (generic
  "HealthLog reminder" body so no cycle event is named on the lock screen).
- Every attempt is recorded in push_attempts via the unchanged dispatcher.

Privacy / disclaimer:
- docs/self-hosting/reproductive-health-data.md — the "no cloud vendor to
  subpoena" framing with the honest residual-threat caveat (your own host,
  provider, backups, and devices remain part of the surface), citing the
  2021 FTC settlement and 2025 verdict as public record only.
- docs/security/cycle-data-threat-model.md — a compact "protects against /
  does not protect against" note, plus README pointers.
- CyclePredictionDisclaimer component (reusing the GLP-1 estimate-disclaimer
  pattern) for every fertility/prediction surface: descriptive, not a
  contraceptive method, not medical advice, never a safe-to-have-unprotected
  -sex claim. 6-locale copy under cycle.disclaimer.

Marc-André BombeckandClaude Opus 4.8 30a7437f4d feat(insights): per-score assessment text + shared metric signal block
Add an additive, non-breaking assessment field to GET /api/insights/derived:
{ text, source, updatedAt } | null, keyed to the requested metric id for the
five per-score ids (READINESS, SLEEP_SCORE, RECOVERY_SCORE, STRAIN_SCORE,
STRESS_SCORE). The field is null when the metric is not one of those or when
its status is not "ok". A deterministic text always fills it — composed from
the score's own contributors, so provider-less accounts and the demo are never
empty — and warmer provider prose overrides it once cached, warmed out of band
so the GET never blocks on a model round-trip. de/en, following the v1.12.12
deterministic-narrative model. The batch grid read returns assessment: null;
the detail sheets use the single-metric route.

Introduce a shared buildMetricSignal() helper: a token-lean, signal-rich
descriptor (current, own baseline, signed delta, spread, normal-swing verdict,
normal-range placement, contributors) computed server-side so the model states
the comparison instead of re-deriving it from raw buckets. Thread it into the
generic per-metric assessment snapshot and lead the base prompt from it. Add a
PROMPT_VERSION constant to the base system prompt so prompt changes are
traceable.

Regenerate docs/api/openapi.yaml.

Marc-André BombeckandClaude Opus 4.8 f25b6aa2dc chore(release): v1.12.12 — deterministic fallback so the period retrospective is never empty
When no AI provider is configured (or before the first AI summary is written),
the period-in-review card stayed empty. Compose a concise, factual, strictly
non-causal summary from the same structured digest the AI prompt is built from
— ranked metric changes vs the prior period, vitals that moved outside their
typical range, and an honest count of statistical associations — and persist it
with a `deterministic` provider marker so a later AI warm replaces it in place.
The read route now warms regardless of provider; the read-never-blocks posture
is unchanged. Fills the no-key demo's retrospective too.

Marc-André Bombeck 1a478d3028 feat(whoop): native-scheme connect redirect and Bearer connect ticket
Two connect-in-app enhancements for the native client.

return_scheme: GET /api/whoop/connect accepts an optional custom scheme,
threaded through the server-side OAuth-state row so it survives the round
trip without ever riding in the URL or cookie. When a valid scheme is
present, the callback's final redirect targets <scheme>://whoop?whoop=
connected|error&reason=... so an in-app web session auto-completes on its
custom-scheme match; absent or invalid, the web settings redirect is
unchanged. Schemes validate against a strict allowlist (custom app scheme
only, ^[a-z][a-z0-9.+-]*$, http/https/javascript/data/file/vbscript
rejected, pinned to dev.healthlog.app). A rejected scheme falls back to
the web redirect and never reflects an arbitrary value.

Bearer connect ticket: a purely Bearer-authenticated client holds no web
session cookie, so it cannot start the handshake through the cookie-gated
connect route. POST /api/whoop/connect/ticket (Bearer) mints a one-time,
~60s, opaque ticket bound to the user; only its HMAC-SHA256 hash is stored
(the raw value never persists). GET /api/whoop/connect?ticket=<opaque>
accepts the ticket in lieu of a cookie, consumes it atomically (single-use,
reuse rejected), sets the nonce cookie, and 302s to WHOOP exactly as the
cookie path. Expired, consumed, or invalid tickets return a typed 401. The
two combine. The daily WHOOP OAuth-state cleanup also sweeps expired ticket
rows.

The ticket query param is added to the egress redaction denylist so the
opaque value never reaches logs or error reports.

Migration 0124 adds whoop_connect_tickets (id, user_id FK cascade,
token_hash unique, expires_at, consumed_at, created_at) and a nullable
return_scheme column on whoop_oauth_states.

Marc-André Bombeck 540abebf09 feat(ops): alarm on a TLS leaf SPKI change for pinned native clients
The native client SPKI-pins the server's TLS leaf certificate. When the
leaf auto-renews (GTS re-issues it roughly every 90 days) the leaf keypair
— and so the SPKI pin — changes, and a client shipped only the old pin
refuses to connect on the next renewal: a silent outage. Nothing
server-side signalled that a client pins the served leaf.

Add a pg-boss monitor that probes the served leaf every 6 hours, computes
its iOS SPKI pin (base64(sha256(DER subjectPublicKeyInfo)) via a raw TLS
socket + X509Certificate), and compares it against the operator's
known-good set in TLS_LEAF_SPKI_PINS (comma-separated for the dual-pin
renewal window). On a served pin outside the set it fails loud: a
tls.pin.leaf_changed wide-event annotation, a system.tls.pin_changed audit
row, and a high-priority SYSTEM_ALERT fanned out to admins through the
existing dispatcher idiom. Transient TLS/network failures annotate
tls.pin.probe_failed and never alarm.

The baseline is an env var, not a persisted last-seen row — a self-learning
baseline would silently adopt the first rotation and suppress the alarm the
pinned client needs; an unset baseline logs the served pin and warns rather
than auto-adopting. The runbook documents extraction, the re-pin + dual-pin
procedure (≥11 days before expiry, ship to TestFlight), and the assumption
that the probed host is the host the client connects to.

Wires the queue into the worker (allQueues + cron + worker), adds the
optional env to the manifest, compose whitelist, and .env example, and
covers the SPKI computation + change detection with a fixture-cert unit
test plus a queue-registration guard.

Marc-André Bombeck 3021d54068 fix(fitbit): skip tombstones on sync, batch backfill writes, bound poll concurrency
Three hardening + performance fixes to the Fitbit/Google Health sync.

Stop soft-delete resurrection. The measurement write probed the existing
row by the `(userId, type, source, externalId)` unique key without excluding
soft-deleted rows, so a reading the user deleted came back on the next hourly
sync (the upsert matched the tombstone and took the update branch — silently
undoing the delete). The write now probes only live rows (`deletedAt: null`)
and treats a tombstone as absent, minting a fresh insert instead. The fresh
insert relies on the partial unique index over `deleted_at IS NULL` to keep
live-row uniqueness; the tombstone sits outside it, and `skipDuplicates` guards
a live-row race.

Batch the backfill writes + collapse the rollup recompute. The write loop
was one upsert per reading (N+1) followed by a per-(type,day) DAY-rollup
recompute, so a multi-year backfill paid thousands of serial round-trips on a
concurrency-1 worker. The existence probe is now a single `findMany` over the
batch; fresh rows go through chunked `createMany`; only already-live rows take a
per-row update for their differing values. On a `fullSync` the per-write rollup
hook is deferred and the touched type-days collapse into one
`recomputeUserRollups(from, to)` pass at the end of the cycle. The incremental
path keeps the inline per-day hook. The `stats:` overwrite contract, the
single-watermark `markSynced`, and the all-403 soft-skip guard are unchanged.

Bound the hourly poll concurrency. The poll synced every connection in one
serial loop, so a single slow Google response stalled the whole cohort. The
cohort now fans out through a bounded `p-limit` pool with per-user error
isolation, extracted into `runFitbitPollCohort` so the contract is unit testable
without exporting worker internals. The accumulators are read after the await to
avoid a compound-assignment lost-update across overlapping pool tasks.

Marc-André Bombeck 686bc1bf30 feat(fitbit): sync Google Health metrics with backfill and poll jobs
Extend the Fitbit/Google Health provider with the read path: the
dataPoints.list client half, the metrics-bundle sync, the poll + backfill
jobs, and the connection-management routes. Builds on the existing OAuth +
credentials + token-refresh layer.

- client: paginated `fetchDataPoints` walker over `safeFetch` keyed on
  `nextPageToken`, encoding each data type kebab-case in the path and
  snake_case in the filter predicate; defensive per-type mappers (finite +
  positive guards) for weight, body fat, daily SpO2, daily HRV, daily resting
  heart rate, daily respiratory rate, intraday heart rate, sleep-temperature
  derivations, and a height profile-seed extractor. `FITBIT_FIELD_MAP` +
  `mapping.md` are the source of truth.
- mapping (no new MeasurementType): weight→WEIGHT, body-fat→BODY_FAT,
  SpO2→OXYGEN_SATURATION, HRV→HEART_RATE_VARIABILITY (SDNN slot, not
  HRV_RMSSD), resting-HR→RESTING_HEART_RATE, respiratory-rate→RESPIRATORY_RATE,
  heart-rate→PULSE, sleep-temp→WRIST_TEMPERATURE, height→User.heightCm when
  null. Steps/distance/energy/floors/VO2 + sleep + workouts stay for a later
  wave.
- sync: `syncUserFitbit` orchestrator with the reauth short-circuit, the
  per-data-class 403 soft-skip (the six Restricted bundles grant
  independently), the all-soft-skipped success guard, and incremental-vs-full
  windows; `upsertFitbitMeasurements` keyed (userId,type,FITBIT,externalId)
  with a 24 h overlap for after-the-fact daily re-rolls, recomputing rollups
  and invalidating status caches. Google refresh tokens do not rotate, so the
  stored refresh token is kept unless a new one is returned.
- jobs: hourly `fitbit-sync` poll (poll-only; Pub/Sub deferred), the
  self-converging boot backfill, and the daily OAuth-state sweep — every queue
  registered in both `allQueues` and a `boss.work` binding, staggered off the
  WHOOP/Withings crons.
- routes: status / sync / disconnect mirroring the WHOOP shape.

Tests cover the mappers, the casing invariant, `fetchDataPoints`, the
orchestrator soft-skip guard, the idempotent upsert, the backfill discovery,
and the queue registration; an integration test pins the upsert idempotency,
the DAY rollup fold, and the Fitbit-vs-Withings per-source no-collapse against
the Postgres testcontainer.

Marc-André BombeckandClaude Opus 4.8 7ab2cbaa56 feat(fitbit): add Google OAuth, credentials, and token refresh
Land the OAuth + credentials half of the Fitbit / Google Health provider,
cloning the WHOOP provider structure and adapting it to the Google identity
flow.

- Client OAuth half (src/lib/fitbit/client.ts): Google authorize-URL builder
  (access_type=offline + prompt=consent), authorization-code exchange, token
  refresh, and a profile fetch for the connection's external user id. Client
  credentials ride in an HTTP Basic-auth header on the token endpoint; the
  four launch Restricted read scopes are pinned in FITBIT_OAUTH_SCOPE. All
  egress goes through safeFetch.
- Non-rotating refresh tokens: getValidToken refreshes at expiry-minus-five-
  minutes, persists the new access token + expiry, and overwrites the stored
  refresh token ONLY when the response carries a fresh one — Google keeps the
  refresh token stable, unlike WHOOP.
- BYO credentials route (PUT/GET/DELETE /api/fitbit/credentials): per-user
  client id/secret stored encrypted on the User columns, built field-by-field
  under requireAuth.
- OAuth state + connect + callback routes: a random base64url nonce backed by
  a 10-minute FitbitOAuthState ledger row carries the (nonce -> userId)
  mapping; the callback validates the cookie/URL state with timingSafeEqual,
  consumes the row atomically (replay/expired/cross-user reason tags),
  exchanges the code, upserts the encrypted FitbitConnection, clears prior
  reauth state, and enqueues the self-converging history backfill.
- Response classifier mirrors WHOOP's HTTP-status buckets; Google signals a
  revoked grant with a 401, so there is no invalid_grant body special-case.

Tests cover the authorize URL, Basic-auth token exchange, the no-rotation
refresh branch (token preserved when omitted, overwritten when present), the
classifier status table, and the OAuth-state nonce mint.

Marc-André Bombeck 5917bba61c feat(insights): period-narrative summary on the overview
Add a calm "your week / month in review" summary to the Insights
overview, generated from the period-narrative context (deltas, personal
bands, FDR-controlled associations, coincident days).

- New insight_narratives table (migration 0113): one durable row per
  (user, period, locale); generated prose AES-256-GCM at rest following
  the coach-message precedent; labels-only provenance stays plaintext.
- generatePeriodNarrative feeds the context into the provider chain with
  a tight, descriptive-never-causal prompt; an insufficient context
  yields no narrative, a missing provider no-ops, neither fabricates.
- Nightly warm cron on week (Mon) / month (1st) boundaries, budget-gated
  per user; the read-only GET enqueues a single-user warm on a cold read.
- Read route is stale-while-revalidate and never blocks on the provider;
  the card renders plain text (no markdown), a single provenance
  disclosure, and a fixed footprint (no CLS). i18n in all six locales.

Marc-André Bombeck 337f024a87 feat(whoop): pg-boss sync workers + self-converging backfill
Build the WHOOP sync layer on the W2 client, mirroring the Withings
queues. A per-resource sync (recovery/sleep/cycle/workout) pulls since
the last cursor with a 24h overlap on recovery/sleep to absorb WHOOP's
after-the-fact re-scoring, maps via the W2 mappers, and upserts
Measurements with source=WHOOP keyed on (userId,type,source,externalId)
so a re-post overwrites in place. Workouts upsert into Workout with
per-workout strain + HR zones in metadata and kJ->kcal energy.

Token refresh persists BOTH rotated tokens (WHOOP invalidates the prior
access and refresh token on every refresh). A self-converging boot
backfill enqueues one full-history sync per un-backfilled connection and
stamps backfillCompletedAt; the discovery query drops completed accounts,
idempotent across reboots.

Every new queue is registered in the worker's allQueues + cron schedule
(recovery/sleep/workout poll catch-all, cycle poll-only, backfill,
oauth-state sweep). IntegrationStatus gains the whoop key + label.

Tests: rotating-refresh persistence, idempotent measurement upsert,
incremental-window overlap, backfill self-convergence, and a
queue-registration inventory guard.

Marc-André Bombeck efa132b1aa fix(insights): make the score candidate finders deterministic
The recovery / stress / strain nightly finders used distinct + take with no
order, so when more than the cap of users qualified the selected set was
arbitrary across runs. Switch to a grouped query ordered by each user's
newest input first with userId as the stable tiebreak, so the cap takes the
most-recently-active users reproducibly. The strain finder interleaves its
workout and active-energy lists so the merged cap favours recency across both
sources.

collision. With the fold reworked to coexist with the canonical daily row
and integration-tested against real rows, flip the default back ON
(DENSE_INTRADAY_RETENTION_ENABLED=true unless explicitly set to false). The
boot-discovery still defers past the startup storm via the boot-delay so it
never contends for the connection pool on a data-heavy tenant; the nightly
03:50 walk and the per-user handler run again.

Marc-André BombeckandClaude Opus 4.8 148e6cd600 fix(insights): score the previous day in the nightly score engines
The Recovery/Stress/Strain crons fire in the small hours (04:45-04:55
Europe/Berlin, ~03 UTC) but scored the CURRENT UTC day, only a few hours
old: Strain missed the just-completed day's workouts and Stress saw a
near-empty intra-day SDNN set and falsely gated as insufficient. Score the
day that just ended (now - 1 day) across all three engines and their
measuredAt / externalId day stamps.

Resolve the previous-day key in one place by extracting the shared score-row
helpers the three engines each duplicated: scoreDayKey / scoreMeasuredAt /
scoreExternalId, the idempotent upsertScoreRow, and the cohort runScoreBatch
tally loop into src/lib/insights/score-row.ts; and loadBaselineProfile into
the baseline engine (the three byte-identical profile loaders + the partial
strain variant now route through it). The derived route should adopt
loadBaselineProfile too.

Marc-André Bombeck c5ba38cebb feat(insights): register the stress, strain, and dense-retention jobs
Wire the two nightly score passes and the dense intra-day retention drain
into the worker. The stress (04:50) and strain (04:55) crons each get a
queue, a schedule, and a single-flight handler; the dense-retention drain
gets a per-user backfill queue with boot discovery (like mean-consolidation)
and folds its steady-state nightly walk onto the existing drain-cumulative
tick, after the daily-mean fold.

A queue not registered in allQueues silently never drains, so a source-grep
guard pins every registration site for all three jobs.

Marc-André Bombeck 6935feda15 feat(insights): compute and store a nightly strain score from workout load
Derive a daily cardio-load proxy from the per-workout heart-rate series
plus active energy. Each workout's HR series scores via Banister's
gender-weighted exponential TRIMP over the fractional heart-rate reserve
(Tanaka age-predicted HRmax, the user's resting HR); the day's TRIMP totals
map to a 0-100 saturating scale. Days with no usable HR series but a
non-trivial active-energy total fall back to an energy-only proxy, with the
path recorded in the result.

Stored as a COMPUTED STRAIN_SCORE row, idempotent per user per day, gated
when neither a usable HR series nor active energy is present.

Standard: Banister 1991; Morton, Fitz-Clarke & Banister 1990 (TRIMP);
Tanaka, Monahan & Seals 2001 (HRmax).

Marc-André Bombeck 57d9cc1674 feat(insights): compute and store a nightly stress score from intra-day HRV
Apple Watch has no electrodermal sensor, so there is no direct stress
measurement to read — what HealthKit does give is discrete SDNN samples
through the day. Derive an honest HRV-through-day PROXY: a suppressed,
below-baseline intra-day SDNN is a recognised marker of higher sympathetic
load. The provenance and label say "HRV-derived proxy" and never imply a
galvanic/EDA reading.

The engine reuses the shared vitals-baseline math (the same SDNN baseline
the wellness index reads), maps the day's below-baseline suppression to a
0-100 score, and stores it as a COMPUTED STRESS_SCORE row — server-owned, a
client can never POST it. It gates and writes nothing below the minimum
intra-day sample floor or without a usable baseline.

Standard: Kim et al. 2018 (HRV and stress meta-analysis); Thayer et al. 2012
(neurovisceral integration). Idempotent per user per day via the nightly job.
2026-06-02 22:49:43 +02:00
Marc-André Bombeck ce2b745cc3 feat(measurements): add a bounded dense intra-day retention tier for HRV/HR
Daytime heart-rate-variability (SDNN) and heart-rate samples need to keep
their intra-day shape long enough for the stress engine to read them, but
the raw per-sample volume must stay bounded. Add a retention tier that
keeps the last 14 days of raw HRV/HR samples and folds everything older to
one daily-mean row via the proven mean-consolidation drain (same idempotent
stats:<HK>:<day> fold, soft-delete, and rollup recompute).

The two dense-tier types are deliberately EXEMPT from the destructive
daily-mean drain allowlist (HIGH_FREQUENCY_MEAN_TYPES) — that drain would
collapse the intra-day shape and soft-delete the raw rows. A regression test
pins both exclusions so a future edit that adds either type to the drain
allowlist fails loudly.

Migration 0108 adds only the partial index that keeps the retention drain's
discovery and per-user scan cheap; the retention bound lives in code so
tuning it never needs a migration.
2026-06-02 22:49:43 +02:00
Marc-André Bombeck 3dcec54726 feat(insights): compute and store a nightly recovery score
Add a recovery-score engine that turns a user's already-stored nightly
signals into a stored 0-100 score. It reuses the readiness blend — the
resting-heart-rate, HRV (SDNN), sleep and respiratory-rate deviation
from the personal baseline, with the null-redistribution the health
score already uses — so the stored series and the live readiness surface
can never drift. The lineage is the recovery-marker literature (Plews
2013, Buchheit 2014): a higher score reads as more recovered. It is a
descriptive wellness proxy, not a clinical or training-recovery
assessment, and it is only stored when enough components are present —
below that floor no row is written rather than a headline from one
signal.

A nightly job computes each eligible user's score and upserts it as a
COMPUTED RECOVERY_SCORE row, idempotent per user per day on the
externalId day key, so a re-fired tick overwrites in place instead of
duplicating. The score is never computed on a page visit. The queue is
registered in the worker's queue inventory, scheduled, and wired to a
handler; a grep guard pins all four points so it cannot silently never
run.

Marc-André Bombeck b13721cc97 fix(insights): stop a timed-out warm from evicting its own freshly-warmed caches
The on-demand force-warm bounds the comprehensive briefing with a 45 s
timeout and then warms the per-status + generic-metric caches itself. The
timeout could not cancel the underlying generation, so a comprehensive that
resolved after the timeout reached its own per-status eviction and deleted
the rows the warm passes had just written — leaving the user back on a cold
cache.

Thread an AbortSignal into the comprehensive generation and abort it when the
timeout fires; the generation now bails out before its write + evict once the
signal is aborted, so a late resolve can never undo the warm.

Also align the force-warm gating with the route: the route admits the job on
the per-user assessment surface, so warm the per-status + generic-metric
cards whenever that surface is enabled, even when the global briefing switch
is off. Only the comprehensive briefing stays gated on the briefing switch.

Factor the per-status cache-action shape into a single helper so the key is
built in one place rather than hand-assembled across the generators, the
eviction sweep, and the ingest debounce.

Marc-André Bombeck 2c6a9f8165 fix(insights): decouple the forced warm sections so a slow comprehensive step cannot starve the rest
The on-demand force-warm ran the comprehensive insight first and only ran
the per-status (7) and generic-metric (~30) assessment passes when that
step returned generated or cached. A slow or stalled comprehensive
generation therefore aborted the entire warm — observed in production as a
102 s run ending with assessments_warmed: 0 — leaving every card cold and
the user back on the lazy 30-60 s on-first-click path.

Give the comprehensive step its own bounded budget and treat a timeout,
error, or skip as non-fatal: the per-status and generic-metric passes now
always run afterwards. Each per-card generator resolves its own provider
chain and bounds its own provider call, so running them after a failed
comprehensive costs a cheap chain-resolve when no provider is configured
and is capped per card otherwise. The result reports each section's
outcome independently, and a timed-out comprehensive is reported distinctly
from a failed one so a partial warm is observable.

Marc-André Bombeck bf5052bb01 feat(insights): add on-demand full assessment warm
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.

Marc-André Bombeck e33911e2d4 feat(insights): generic per-metric assessment coverage for HealthKit metrics
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.
