REFERRAL joins the document-kind enum (Überweisung — LOINC 57133-1 / ePA
ANF). inbound_documents gains content_sha256 (plaintext hash for same-user
duplicate detection; pre-existing rows stay NULL) and content_codec
(base64v1 legacy string codec | binary2 binary codec, explicit column —
never header-sniffed), plus a partial unique index that allows at most one
LIVE row per (user_id, content_sha256) so a tombstoned document never
blocks a re-upload.
document_condition_links is the m:n join between a document and an
illness/condition episode (a discharge letter legitimately touches two
conditions); both sides cascade. app_settings carries the two admin-tunable
limits (per-file cap, default 25 MiB; per-user quota, default 1 GiB) and
users the nullable per-user quota override.
Task: W1-T1.
Two new self-report instruments join the mental-wellbeing engine on the
existing PHQ-9 / GAD-7 infrastructure:
- WHO-5 Well-Being Index: 5 items on the 6-point 5..0 scale over the last
two weeks; the reported total is raw-sum x 4 (0-100) per the official
WHO scoring (WHO/UCN/MSD/MHE/2024.1, CC BY-NC-SA 3.0 IGO). A total of
50 or below follows the WHO comment (below 50 = indication for further
assessment).
- Sleep Condition Indicator: 8 DSM-5-aligned items, 0-4 each with
item-specific anchors, total 0-32, higher = better sleep; a total of
16 or below maps to the probable-insomnia range of the source
publication (Espie et al., BMJ Open 2014;4:e004183, CC BY-NC,
(c) Sleepio Limited).
The instrument registry generalises rather than forking: per-item answer
ceilings, option order/label schemes, recall-stem captions, a reported-
score multiplier, score direction (higher-is-better inverts the follow-up
threshold), per-instrument attribution lines, and the validated-item
locale set are now instrument properties. Scoring stays server-
authoritative; the create route validates the per-instrument answer
ceiling and projects the total onto a COMPUTED WHO5_SCORE / SCI_SCORE
measurement row (never client-attributable), which also auto-satisfies a
planned screening reminder. Migration 0226 adds the enum values
(additive, idempotent). OpenAPI regenerated.
Neither instrument carries a self-harm item; the PHQ-9 item-9 crisis
routing is unchanged.
Each completed PHQ-9 / GAD-7 administration already projects its total
onto a PHQ9_SCORE / GAD7_SCORE measurement row (unit score, linked via
externalId assessment:<id>). Those rows were attributed MANUAL — a
client-writable source. The projection is a server-derived value, so it
now writes source COMPUTED, the same server-owned source RECOVERY_SCORE
uses: no client write surface can attribute COMPUTED, so a forged score
trend point cannot enter through the measurement POST. Migration 0225
re-attributes the existing assessment-linked projection rows; a score a
user typed into the generic measurement form keeps MANUAL. OpenAPI
description updated and the spec regenerated.
Introduce the data model behind a Google Health provider that reads
Fitbit, Pixel Watch, and Fitbit Air data through a user's Google account.
- GoogleHealthConnection: 1:1 with the user, encrypted access/refresh
tokens, token expiry, external Google user id, sync high-water-mark,
and a needsReauth flag for the periodic re-consent that Google's
Testing-mode clients require.
- GoogleHealthOAuthState: the connect-flow nonce ledger with the PKCE
verifier.
- Two encrypted BYO-client columns on User for the operator's own Google
OAuth client id and secret.
- GOOGLE_HEALTH added to the measurement_source enum.
Migration 0224 mirrors the existing integration shape: a standalone
enum-add, guarded CREATE TABLE / ADD COLUMN, forward-only and idempotent.
Renumber the custom-metrics migration to 0223 (the next free slot on the
trunk) and cut the release: version bump, regenerated OpenAPI contract,
service-worker stamp, and CHANGELOG entry.
Add a user-defined custom-metric store alongside the built-in measurements
on the Measurements surface. A user defines an arbitrary metric (name, unit,
optional target window, decimals, description), logs values, and charts them.
The store is a separate generic catalog + values pair, isolated from the
closed measurement-type system: not synced, not in FHIR, not in insights —
log and chart only. Names and units are plaintext, mirroring the biomarker
catalog. The inline list lives beneath the measurement list (no new nav
entry); tapping a metric opens a detail page with the trend chart, target
band, stat strip, and an editable value history.
Migration 0224 adds custom_metrics and custom_metric_entries.
The insights alert cards computed medication compliance with the naive
`schedules.length × days` denominator, so a fully-adherent weekly
injectable read ~14% and fired a false low-compliance alert (and a paused
medication mis-fired the same way). Route the alert path through the
canonical `calculateCompliance` engine like every other compliance
surface — pause eras, schedule revisions and dose windows honoured.
Document confirm: committing a numeric observation against an existing
biomarker silently replaced the stated unit with the catalog's, with no
conversion — a stated "6.1 mmol/L" against a mg/dL marker committed
"6.1 mg/dL". Reject on a unit mismatch (fail closed) so the user
reconciles on the review screen, the same posture as the unit-required
guard.
Wire grip strength, waist (with waist-to-height) and pain into the
briefing feature set and the grounding allow-set so the clinical-depth
signals reach the daily narrative; the mental-health screeners stay
excluded by construction.
Biomarker detail: fall back to a generic description for catalog-less
markers, and keep the heading + description with a retry on the error
state. Collapse the medication External-API and Lifecycle groups by
default. Re-enable the insights scroll-to-top regression and assert the
shipped main-content reset.
Align the EN haemoglobin/haematocrit display names to British spelling.
Drop the redundant `(userId, deletedAt)` index on inbound documents — a
strict prefix of the new three-column index. Trim the dead
MedicalDisclaimer variants to the one live `dataPosture`. Move the
crisis-resources card off the retired amber tint to a calm
destructive-subtle border. Add a registry invariant asserting every
biomarker signal key resolves to a real catalog slug.
Default documentDate at store time. A store-only upload no longer lands
with a NULL filing date: when the client omits one, default it to the
upload day so the column is always set on a stored row. The library list
sorts, groups, and range-filters on the same effective date the UI shows,
so undated uploads no longer mis-sort under nulls-last, break date-group
headers, or fall through the range filter. The date stays user-editable
and may be cleared back to NULL via PATCH.
Block re-extraction once any fact is APPROVED. A partially-confirmed
document stays EXTRACTED, which the CONFIRMED guard does not catch;
re-extracting would delete the approved facts (severing the committed
record's provenance) and re-stage them as PENDING, letting a second
approval duplicate the committed lab / condition / medication. The
extract route now refuses with 409 (documents.inbound.alreadyPartlyConfirmed)
when approved facts exist; the user must finish reviewing or discard first.
RFC 5987-encode the original-download filename. The Content-Disposition
now carries both an ASCII filename= fallback and a filename*=UTF-8'' value
so a non-ASCII name survives intact; the stored set is inline-safe by
construction, so the dead attachment branch is removed.
Add a light per-user rate-limit backstop to the original-read, PATCH, and
DELETE routes (generous; self-DoS only — the routes are owner-scoped).
Lean the list counts: tally facts for the whole page in one grouped count
instead of materialising fact-id rows, and exclude REJECTED facts from
factCount. Extend the documentDate index with deleted_at to cover the
list scan. Document the deliberate plaintext-title PHI tradeoff at the
column and the store site.
Invert the inbound-documents surface from an OCR inbox into a document
library: a file can be stored without any AI provider, and extraction
becomes an opt-in action on top.
- Migration 0222: add `title` + `document_date` columns, a
`(user_id, document_date)` index, the richer kind taxonomy
(lab/imaging/prescription/insurance/vaccination), and a STORED status
made the column default. The status enum is recreated so the new value
can be set as the default within the migration transaction; kind values
use ADD VALUE. Nullable columns, no backfill.
- POST /api/documents/inbound is now store-only: bounded multipart read,
magic-byte MIME sniff, AES-256-GCM at rest, persisted as STORED with no
provider/consent/budget call and no egress.
- POST /api/documents/inbound/[id]/extract carries the relocated
extraction gauntlet (resolve provider, consent, rate-limit, budget, run,
reconcile, stage facts) against an already-stored row; absent a provider
it 422s the enhancement only and leaves the stored document intact.
- PATCH /api/documents/inbound/[id] edits title/kind/documentDate
field-by-field, owner-scoped by session userId.
- GET /api/documents/inbound gains search, kind filter, documentDate
range, sort, and keyset pagination via the parameter-bound query builder.
- Extend the validation schemas + DTO, regenerate the OpenAPI contract,
and add route tests for the store/extract/edit/list paths.
The screener POST hardcoded source=WEB and ignored any client-supplied
externalId, so the native client could not tag provenance and an outbox
replay beyond the 24h idempotency-key window minted duplicate
administrations plus duplicate trend points.
Accept an optional closed source enum (WEB|IOS, default WEB) and an optional
bounded externalId, and persist both. Deduplicate on (userId, externalId)
when present: the route returns the existing administration on replay, and a
partial unique index over (user_id, external_id) WHERE external_id IS NOT
NULL (migration 0221) backstops a concurrent insert race (P2002 resolved to
the winner). The derived *_SCORE measurement keeps its stable per-assessment
externalId, so dedup at the assessment level prevents duplicate trend points.
Item answers stay encrypted and out of AI/MCP/export. Regenerate OpenAPI.
The inbound-document store encrypts the raw upload
(`inbound_documents.content_encrypted`) because it is sensitive clinical
data, but the per-fact staging columns persisted the same class of data in
the clear: `extracted_facts.data_json` held the transcribed clinical values
(diagnosis text, lab values, medication names, stated codes) and
`provenance_json` held the verbatim source span (up to 2000 chars copied
straight out of the report). The at-rest guarantee was defeated for staged
facts, which persist through PENDING and are retained after the decision.
Convert both columns to the AES-256-GCM `*_encrypted` BYTEA convention shared
with the note columns, going through the same Bytes codec. The upload and
fact-edit paths encrypt on write; the confirm path decrypts at commit time to
write into the normal structured stores, so the review-then-confirm flow is
unchanged. Reads are fail-closed (a bad key id throws).
Register both columns in the encrypted-columns registry and the key-rotation
script so a dropped legacy key cannot strand them (the guard test enforces
both). Migration 0220 swaps the plaintext JSONB columns for the encrypted
BYTEA columns; pre-confirm staged rows are ephemeral and cannot be
re-encrypted in SQL, so any left by a pre-release build are dropped rather
than retained as plaintext (their parent document keeps its encrypted
original).
Add `User.homeSince` (nullable effective-from instant) and a `DEVICE` value to
the location-source enum (migration 0219). `homeSince` records when the home
location became effective so day resolution can attribute a past day to the
home only on/after that instant, rather than to the current home for every past
day. Existing accounts with a home get `homeSince` stamped to the migration
instant; their deep past is filled by explicit location periods instead.
`DEVICE` is reserved for a future client-supplied coarse per-day location: the
enum value and the wire contract accept it now so the resolver can rank it
later without rework. Nothing writes it server-side yet.
Add the opt-in environmental-context store: per-day EnvironmentContext
observations (temperature, daylight, sunshine, precipitation, pressure,
humidity, cloud, weather code) keyed by user + day and location, plus the
manual EnvironmentTravelLocation overrides and the coarse home-location
columns on the user. Location is city-level by design; the weather model
needs no finer than ~10-25 km and no GPS track is ever stored.
Store an uploaded doctor report / discharge letter and stage extracted
structured facts for review. Two models:
- InboundDocument: the uploaded document, raw bytes encrypted at rest via
the shared AES-256-GCM Bytes codec (content_encrypted), with queryable
metadata (kind, mime, size, status, report date).
- ExtractedFact: the review-then-confirm staging row — fact type, status,
per-field provenance, a confidence score, and a needs-review gate, plus
the FHIR-staged payload (stated codes/status only) as JSONB.
Wire content_encrypted into the encryption-key rotation registry and the
rotation script so a key drop never strands a stored document.
Introduce two structured health-record tables, kept as reference records
(not time-series signals):
- `allergies` — AllergyIntolerance-style: substance + category + type +
severity + status + optional onset. The substance label stays queryable
plaintext; the free-text reaction and note are AES-256-GCM encrypted
(`reaction_encrypted` / `notes_encrypted` BYTEA).
- `family_history_entries` — one condition per relative: relationship +
condition label + optional age-at-onset; the free-text note is encrypted.
Both are owner-scoped and soft-deleted. Migrations 0215/0216 are additive
and idempotent. The three new encrypted columns are registered in
ENCRYPTED_COLUMNS and wired into the key-rotation script, so a key drop can
never silently strand them undecryptable.
Add the validated mental-health self-assessment surface, beside mood tracking
(never replacing it) and off by default:
- MentalHealthAssessment stores per-item answers in a single AES-256-GCM Bytes
blob (registered for key rotation); only the server-authoritative total,
severity band, and item-9 flag are denormalised. The total projects to a
PHQ9_SCORE / GAD7_SCORE measurement row so the trend rides existing infra
without ever exposing item content.
- Item-9 safety: any non-zero PHQ-9 self-harm answer surfaces a calm,
locale-aware crisis-resource set (DE: TelefonSeelsorge 0800 111 0 111 / 112;
international fallback) and stamps crisisShownAt. No clinical interpretation,
no AI ingestion of item content, no third-party alerting.
- API + OpenAPI: POST/GET /api/mental-health/assessments; the response excludes
raw item answers by construction. Required Pfizer/PHQ attribution lives in the
instrument module, rendered verbatim.
The screener scores are kept off the Coach snapshot and MCP surfaces, and out of
exports by default — item content never reaches the AI pipeline.
Add the clinical-signals wave's new measurement types and wire them through
the signal registry so FHIR, correlation eligibility, ingestion, and the
measurement-list surfaces derive from one definition each:
- MeasurementType: PHQ9_SCORE, GAD7_SCORE, GRIP_STRENGTH, PAIN_NRS,
WAIST_CIRCUMFERENCE, WAIST_TO_HEIGHT (+ AssessmentInstrument enum and the
MentalHealthAssessment model that backs the screener scores).
- Registry: the six measurement/score signals plus the longevity lab panel as
kind:"biomarker" entries; the FHIR golden fixture is regenerated in lockstep.
Grip-strength and waist-to-height carry a null LOINC (NEEDS-VERIFY) and emit a
local text concept until a stable code is confirmed.
- FHIR: add the survey observation category for the screener / pain signals.
- Labs: extend the biomarker catalogue with ApoB, Lp(a), fasting insulin, and
the omega-3 index; add LOINC codes for those plus GGT and hs-CRP; add a
computed HOMA-IR helper.
- Exhaustive maps updated to keep the enum coverage, category, list-meta, and
personal-record drift guards green.
A cluster of related correctness gaps in the compliance denominator and the
insight surfaces that read it:
- Paused medications. A doctor-ordered pause flipped `active` off and stamped
`pausedAt`, but resume nulled `pausedAt`, so the interval was irrecoverable
and every paused day became a missed dose after resume — collapsing
adherence across the Health Score, the BP gate, the Coach snapshot and the
report. Persist pause intervals as durable eras (new `MedicationPauseEra`,
migration 0211), close the open era on resume, thread the eras through the
compliance context and drop slots inside a paused interval from the
denominator. Every compliance call site now fetches and passes the eras.
- Health Score eras. The Health-Score fast path was the only compliance
caller that skipped the shared schedule select and schedule revisions, so
after a schedule edit it scored past days against the current schedule
while every other surface used the historical era. Switch it to the shared
select and thread revisions (and pause eras) like the canonical path.
- Insight bucketing timezone. The per-metric status series bucketed every
user in Europe/Berlin, so a near-midnight reading landed in the wrong day
and the relative-day phrasing was off for non-Berlin self-hosters. Thread
the resolved user timezone and key off `userDayKey`.
- Correlation significance. User-facing correlations surfaced from five
paired points with strength read straight off the coefficient. Route them
through the rigorous engine (at least twenty pairs, Student-t p below 0.05)
so small-N coincidences no longer render as confident findings.
- Resting-pulse input. The mood-versus-"resting pulse" correlation fed the
raw PULSE day-mean, which folds in workout HR, under a "Resting pulse"
label. Feed `resolveRestingPulseSeries` (clean RESTING_HEART_RATE, else a
daily low-percentile proxy) so the label matches the input.
Cap and page the unbounded reads that let a multi-year tenant pull its
whole measurement history into memory on hot paths.
- extractFeatures: read newest-first with a 6000-row cap (mirrors the
Coach snapshot) and reverse to ascending, so a 365-400 day window no
longer materialises hundreds of thousands of PULSE / glucose rows per
Coach turn and nightly briefing. Full-history extremes still come from
readAllTimeExtremes, so the cap never relabels an extreme.
- Add a (userId, measuredAt) index on measurements (migration 0210) for
the type-less range scans that extractFeatures and the consolidation
passes drive; the existing (userId, type, measuredAt) cannot serve them
as a prefix.
- runConsolidation: keyset-paginate the per-(user, type) source scan on
(measuredAt, id) instead of one unbounded findMany, removing the giant
single result-set allocation that drove the boot storm. Output is
identical; covered by a paging unit test.
- Stagger the boot-time backfill enqueues with increasing startAfter
offsets so the heavy full-history loads no longer all drain in parallel
onto one tenant at startup. Non-boot callers keep their immediate send.
- Backups: replace load-all-then-stringify with paged narrow-select reads
for the weekly and off-host writers, bounding transient heap. Off-host
still includes soft-deleted rows. Covered by a serialize/restore
round-trip test.
- Drop the per-request auth.bearer.success audit insert; the wide event
already records auth_method and user_id, so the polling client no longer
drives a write + pool checkout on every request. Failure-path audit
stays.
- Coach conversation detail: cap the message include to the newest 200 so
a long thread no longer decrypts every message on each open; response
shape unchanged.
- Admin audit-log: floor the scan at the retention horizon so the listing
and its count stop sweeping open-ended over the substring filters.
Encrypt MedicationSideEffect.notes, MedicationDoseChange.note and
MedicationInventoryItem.notes with AES-256-GCM, closing the last plaintext
PHI columns left after the v1.23 note-encryption rollout. Add the three
*Encrypted Bytes columns (migration 0208), register them in the encrypted-
column rotation set, route every read/write through the note cipher, and add
a transactional fail-closed boot-time backfill for legacy rows. Plaintext
columns drop in a later release once the backfill reports zero remaining rows.
Require a fresh second factor on password change for MFA-enrolled accounts,
matching the existing step-up on MFA-disable and recovery-code regen. Redact
free-text note values from the Zod validation excerpt that can reach a wide
event.
Combine the remote MCP server (stdio + remote /mcp + OAuth 2.1 + read
tools + deep-value reads + a confirmed, audience-bound write surface)
with the v1.23 account-security line (MFA, known/trusted devices,
free-text note encryption).
- schema: keep every v1.23 User relation (MFA, known/trusted devices)
alongside the McpOAuthConnection relation; the MeasurementSource enum
carries the MCP value.
- api-handler: the MCP audience guard (a token scoped to
health:read/health:write is bound to /mcp and refused a REST write)
and the step-up MFA helpers coexist.
- maintenance queues: register the MCP token-cleanup sweep next to the
note-encryption backfill and key-rotation queues; shift it to 04:00
so the two daily discovery ticks do not collide.
- migrations: renumber the MCP migrations to 0206/0207 so they follow
the v1.23 chain (0199-0205).
- MCP mood writes route the note through the v1.23 at-rest cipher.
Add an opt-in "remember this device" at the second-factor step. On opt-in
a random token is minted, set in an httpOnly+Secure+SameSite=Strict cookie,
and only its HMAC hash is stored in a new TrustedDevice table. A later sign-in
from the same browser still requires the password (factor 1); a matching,
unexpired trusted device lets the login skip factor 2 only.
The token is never accepted for step-up — a trusted-device login does not stamp
mfaVerifiedAt — so a stolen device cookie cannot reach a destructive action.
Trusted devices are listed and revocable from the security surface, are revoked
wholesale when the second factor is removed or the user signs out everywhere,
and cascade away on account deletion. A recovery-code login never trusts the
browser. Migration 0204 adds the table (and the instance-wide mfa_required
policy column that the enforcement work reads).
Drop the in-app bug-report surface end to end: the user submission page,
the feedback intake and admin inbox, the optional GitHub-issue
escalation, the operator config, and the dedicated achievement badges.
- delete the /bugreport page and the bugreport / feedback / admin-feedback API routes
- drop the Feedback model, its enums, and the AppSettings GitHub-issue and enable columns (migration 0205)
- remove the admin Feedback section, the Bug Report integration card, and the system-status row
- drop the bug-report nav entry and the app-settings provider that only carried its flag
- remove the bug-hunter achievement badges and their metric
- prune the related i18n keys across every locale and the encrypted-column and key-rotation registries
On a completed sign-in (password, second-factor, or passkey) from a device or
location not seen before, send one notification through the dispatcher cascade,
honouring the user's per-channel preferences via a new SECURITY_ALERT event
type. Dedupe on a one-way, per-user fingerprint: a SHA-256 over the userId, the
coarse User-Agent family, and a country/ASN-level geo signal, stored in the new
user_known_devices ledger (migration 0203). The first sighting of a fingerprint
alerts and records; later sightings only bump last-seen and stay silent. The
raw User-Agent and IP are never persisted — only the salted hash and a coarse
label. Registration records its device silently so a fresh account does not
alert on its own first session. The whole path is fire-and-forget and never
blocks or fails a sign-in.
Add the TOTP enroll/confirm/disable surface and Argon2id-hashed recovery
codes as the v1.23 second factor.
- totp.ts wraps otpauth (zero-dep) pinned to the interop floor (SHA-1, 6
digits, 30 s) with a +/-1 drift window. Replay protection persists the last
accepted time-step per account (User.totpLastStep, migration
0202_v123_totp_laststep) and rejects any step that is not strictly newer,
so a captured code dies the instant it is accepted once.
- recovery-codes.ts issues ten single-use, high-entropy codes, Argon2id-
hashed at rest, shown once; regeneration replaces the entire prior set in a
transaction and verification burns the matched code with a guarded update.
- The TOTP secret is stored AES-256-GCM encrypted (already registered in the
encrypted-columns registry + rotation script); decrypt is fail-closed.
- Routes: setup (pending secret), confirm (activate + issue recovery codes),
disable (step-up + current factor), recovery-codes/regenerate (step-up).
Setup/confirm are cookie-only; disable/regenerate add requireFreshMfa.
- scripts/disable-mfa.ts is the operator escape hatch for a locked-out
self-hoster, audited, run via pnpm dlx tsx.
Lay the account-security and data-sovereignty substrate for v1.23. No
user-facing behaviour yet — schema, crypto registry, redaction, and the
note-encryption data path only.
Schema + migrations:
- 0199 — User totp_secret_encrypted / totp_confirmed_at / mfa_enforced /
passkey_upgrade_nudge_dismissed; Session mfa_verified_at / last_active_at;
Passkey last_used_at. All additive, nullable / defaulted.
- 0200 — mfa_challenges (single-use step-up ticket; only the ticket hash is
stored, so no session or token is ever minted before the second factor),
mfa_recovery_codes (Argon2id at rest), webauthn_mfa_credentials (second-factor
keys, kept separate from passkeys, which remain the passwordless-primary set).
- 0201 — mood_entries.note_encrypted + measurements.notes_encrypted (BYTEA),
matching the existing free-text encrypted-note convention.
Free-text health notes:
- New writes encrypt the mood / measurement note into the *_encrypted column and
null the legacy plaintext column; reads prefer the ciphertext and fall back to
plaintext only for not-yet-migrated rows, via a single read/write helper.
- A boot-time job migrates existing plaintext rows in an idempotent,
transactional, fail-closed pass (encrypt, then null the plaintext, per row in
one transaction; safe to re-run; a row with content is never left both-null).
- The legacy plaintext columns are kept this release and dropped in a follow-up
once the backfill reports zero remaining rows — the same boundary the
key-rotation playbook uses before dropping a legacy key.
Crypto coverage:
- Register the three new encrypted columns and wire them into the key-rotation
script so a rotation never orphans them.
- Extend the observability and log redaction denylists so TOTP secrets, MFA /
recovery / backup codes, and export passphrases never reach a wide event.
Append an MCP value to MeasurementSource (migration 0196, additive enum
extension) so a row logged through the remote MCP endpoint is distinguishable
from MANUAL/TELEGRAM provenance and gets an isolated idempotency namespace
(userId, type, MCP, externalId). The value joins the read enum so existing
read/response shapes decode the rows; the REST batch and single-POST write
surfaces still reject it (server-resolved only). Regenerate the OpenAPI
contract for the additive enum.
The AI-settings migration altered "User" but the table is "users"; deploy
would abort with relation "User" does not exist. Correct the identifier and
make both v1.22 column additions rerun-safe with IF NOT EXISTS.
Add three per-user AI settings, all configured in the app (no new env vars),
behind one migration (0198):
- Response timeout (seconds). A per-user upstream timeout threaded onto the
provider call. A local/self-hosted backend can take more than the legacy
60 s default to load a model on the first request, which timed the Coach
out before the first token. Defaults to a generous ~180 s when unset;
validated to 10–600 s.
- True token streaming for the local OpenAI-compatible client. The client now
POSTs with stream:true and parses the SSE delta chunks, emitting tokens as
they arrive, with a per-idle-gap timeout instead of a whole-call ceiling and
a graceful fallback to the buffered path when a server cannot stream. The
Coach route runs the provider call inside the response stream behind a
keepalive heartbeat so a reverse proxy no longer idle-drops the connection
during model load or generation. Grounding, refusal, and sentinel-stripping
still run on the complete reply before any token reaches the client.
- Dedicated document-scan (Lab-OCR) provider. Off by default — the OCR path
uses the main provider chain. When enabled, lab-report processing resolves a
separate provider/model/key, with a hint when the chosen model is not
vision-capable. The new key column is AES-256-GCM at rest and registered in
the encrypted-columns registry and the rotation script.
i18n: EN + DE translations for the new Settings → AI strings (other locales
carry interim copies to keep locale parity green).
Add the medication-class to target-vital map and the adherence-to-vital
storyline so the Coach can surface, association-only, when an adherence dip
lines up with a drift in the vital that medication targets. Never causal,
never a dose-change suggestion; dose questions defer to the prescriber.
Add an in-repo CUSUM / binary-segmentation changepoint detector over DAY
rollups with a high firing bar (persistence plus within-segment-spread
magnitude) so the Coach can name a dated, sustained level shift instead of a
vague "lately", and stays silent when no break clears the bar.
Surface which source recovery is read from when two sources materially
diverge, with the honest reason, instead of silently averaging.
Lay the n-of-1 experiment substrate: a nullable encrypted outcome column on
coach_plans (migration 0197), the review_due / reviewed lifecycle statuses
wired into the encrypted-column registry and rotation script, and a daily
worker that reads the experiment result back in the user's own before/after
numbers — association-only, honest-null, no cheerlead on an adverse trend,
and routing a worsened vital to the clinician. The user-visible read-back
stays behind COACH_EXPERIMENT_VERDICT until its review cases clear.
Extend the outbound dose screen to catch experiment-shaped dose changes
(halve / skip / stop a medication to test it). Add evaluation cases and unit
tests for each new surface.
Harden the remote MCP endpoint and the in-repo OAuth bridge against the
adversarial review of the milestone branch. The two ship-blockers made the
"read-only, revocable" promise false; the rest tightened the surface.
Audience binding at the resource server: a token whose only grant is the new
`health:read` scope is the MCP read credential. The REST edge now accepts it on
safe (read) methods and refuses it on writes/deletes with 403, so a connector
token can read over `/mcp` and GET routes but can never POST/DELETE the record
despite a "read-only" consent. The `/mcp` resolver is unaffected.
Revocable, theft-detectable refresh tokens: refresh artifacts now anchor to a
persistent connection row. Revoking a connection stops every future refresh and
kills its access tokens; a replayed (already-rotated) refresh is treated as
theft and revokes the whole connection. Connections surface in settings as the
unit a user can disconnect. The old access token is revoked on rotation.
Also: fail closed on the OAuth/`/mcp` surface when no canonical origin is
configured and mark the discovery documents non-cacheable; honour the global API
kill-switch on `/mcp`, `/token`, `/authorize`, and `/register`; cap the CIMD and
registration body reads while streaming instead of after; show the verified
client origin on consent; validate CIMD redirect-URI schemes; assert same-origin
on the consent POST; and add a daily prune for expired connector tokens.
New migration 0195 adds the connection anchor and links access tokens to it.
Introduce a third Coach memory type alongside facts (durable traits) and
plans (standing if-then habits): a time-anchored "bring this back later"
reminder with a due moment and a done state. The free-text note is
AES-256-GCM ciphertext via the shared Bytes codec; metric, status, the
trigger fields and the dates stay plain so the sweep and the injection
picker rank and filter without a per-row decrypt.
Migration 0196 is purely additive (status and trigger_kind are app-side
closed enums, not DB enums). Register the new note_encrypted column in the
encrypted-columns registry and the rotation script so a key rotation can
never silently skip it.
Add a `hidden` boolean to the Biomarker model (migration
0195_biomarker_hidden) so a marker the user no longer needs can be
soft-removed instead of deleted: it leaves the active catalog and the
lab-entry pickers but keeps its readings and canonical unit/range.
Thread `hidden` through the DTO, the update schema, the PUT handler
(field-by-field), and the list endpoint (visible markers first). Regen
the OpenAPI contract.
Add a CoachPlan model: durable, user-scoped if-then implementation plans
the Coach proposes and the user confirms. The background memory-refresh
pass extracts plans the user agreed to and writes them as "proposed"; only
the user-facing PATCH on /api/coach/plans/[id] activates one. The free-text
cue / action / target are encrypted at rest with the shared Bytes codec;
metric, status and dates stay plain so the injection picker ranks without a
per-row decrypt. Active plans fold into the Coach snapshot's memory block
and survive the prompt-budget drop alongside facts. List, confirm and
soft-delete routes are Coach-gated and narrow the owner from the session.
Key the dashboard-snapshot query cell by locale so a locale switch reads
freshly localised tile copy on its own cell instead of serving the prior
locale's prose until the slot goes stale. The zero-arg key stays
byte-identical, so every prefix-based invalidation keeps reaching the
locale-keyed cells; the offline-banner and preloader match on the prefix.
Migration 0194 (additive CREATE TABLE). Encryption-rotation registry and
script cover the three new Bytes columns.
The per-bucket OLS accumulators stored x on the raw epoch-day axis (x ~ 20540),
so sum_xx accumulated past ~1e10 and the square shed ~10 of a double's
significant digits before the value was ever stored. The sub-day x detail was
lost at accumulation time, which no read-side identity can recover; an
ill-conditioned window's composed slope/r2 then drifted from the live REGR_*
probe past the parity gauge.
Rebase x to a fixed origin (epoch-days of 2020-01-01) at write time so the
squared terms stay O(1e7) and exact. Slope, r2, and population sd are invariant
under the affine x-shift, so the live raw-epoch probe still parity-matches the
cross-bucket compose; composeRegression needs no formula change. The per-bucket
slope/r2 columns stay on the raw axis (shift-invariant).
Migration 0193 recomputes sum_x/sum_xy/sum_xx from measurements on the rebased
basis, one set-based update per granularity. Recompute-from-source is idempotent
and rerun-safe; it touches only rows that already carry the accumulators and
leaves pre-migration NULLs for the boot re-fold.
Un-quarantine the DST-boundary parity test: it now matches live REGR_* within
the existing 1e-9 relative bound, with the WEIGHT case still bit-identical.
Mirror the time-format preference with a per-user date display
choice. AUTO follows the locale convention, DMY/MDY/YMD pin the
field order. Additive, rerun-safe migration; existing rows read AUTO.
Retarget the Fitbit integration from the Google Health API (which needs
annual CASA review — a wall for self-hosters) to the classic Fitbit Web
API with PKCE and rotating refresh tokens, so a self-hoster can connect
with an instant developer app (migration 0191 adds the PKCE verifier).
Transport-only fork; the ingest, dedup, source-priority, backfill and
poll paths are reused. Intraday HR and skin temperature are not mapped
(no honest slot); the integration stays experimental.
The classic Fitbit Web API authorises with PKCE (Authorization Code + S256),
so the connect route mints a code_verifier and the callback presents it on the
token exchange. Carry it on the short-lived FitbitOAuthState row.
Additive + nullable (migration 0191): a legacy in-flight row carries no
verifier, so the change is reversible and rerun-safe with no data loss.
Windowed slope, r2 and population sd still ran a live REGR_*/STDDEV_POP
query over the raw measurements partition on every warm-rollup request,
because the per-bucket mean cannot reconstruct an OLS regression over the
raw points in a window. The per-bucket sd/slope/r2 columns are a
within-bucket fold and do not compose linearly across DAY buckets.
Add the four regression-accumulator sums Postgres folds for REGR_* /
STDDEV_POP - sum_x, sum_xy, sum_xx, sum_yy - per (user, type,
granularity, bucketStart, source) over the same canonical-source rows
the live query reads, with the x-axis in epoch days. With n = count and
sum_y = mean*count already stored, all six terms are additive across
buckets, so a 7/30/90-day slope/r2/sd composes from the summed
accumulators with a bit-identical result to the live closed form.
Migration 0190 adds the four nullable columns; nullable keeps it
additive so existing rows read NULL until the boot re-fold refills them
(mirrors the v1.4.39 sum_value rollout). The populator emits the four
SUM terms inside the existing aggregate (no extra round-trip) and
persistRollupRows writes them. composeRegression / composeWindowedRegression
evaluate the closed form from already-collapsed buckets and return a full
miss when any in-window bucket lacks accumulators, so the reader falls
back to live SQL rather than composing a partial window.
Two related changes to the Telegram bot's data path.
One chat ⇄ one account. `User.telegramChatId` is now UNIQUE (migration
0189, defensive pre-clean of any pre-existing duplicate binding). The
inbound webhook resolves the user from the chat id, so a chat shared
across two accounts would route a reply or button tap ambiguously. The
index is over a nullable column, so an unlinked account (null chat id)
never collides — only two accounts binding the same non-null chat id are
rejected.
Numeric measurement capture. A numeric reply to a measurement reminder is
now captured as a Measurement (`source = TELEGRAM`, added to the enum in
0189). On "Erledigt" for a reminder that names a single-value metric, the
bot offers an optional value prompt via force_reply; a numeric reply is
written through the shared `logTelegramMeasurement` helper — same range
guard, canonical unit, cache + rollup refresh as the manual route. The
reply binds to the reminder and user through a TelegramPromptContext keyed
on the prompt message id (the same strict chat/message binding the
mood-note path uses); the userId is never read from the payload. Comma
decimals are tolerated; non-numeric and out-of-range replies get a calm
hint and write nothing; the reply self-cleans on the ~30-min sweep. Blood
pressure (two values) is out of scope for the single-numeric path and
keeps its satisfy-only flow.
Guard the CREATE TABLE + both CREATE INDEX statements with IF NOT EXISTS so
a re-run on a database that already has the table is a no-op, matching the
guard convention every other recent migration ships with. Semantics are
unchanged — same table, same columns, same indexes.
The v1.19.0 hourly heart-rate bucket
(`stats:HKQuantityTypeIdentifierHeartRate:<UTC-hour>`) shipped avg-only:
one PULSE row carrying the hour's mean bpm. Add the hour's min/max so a
client can render the intra-hour range without re-uploading raw samples.
- Two nullable columns on `measurements` (`value_min` / `value_max`),
migration 0188. Set only on a well-formed hourly HR bucket row; null for
per-sample readings, per-day cumulative totals, and manual entries.
- Batch ingest threads the spread through the same unit conversion as the
average and persists / overwrites it alongside `value` on the bucket
row, pinning it null everywhere else.
- The series reader returns the spread for `kind=pulse` (null on a
per-sample PULSE row); the OpenAPI Zod contract documents both fields on
the batch entry and the series point. The avg path is unchanged.
Add TelegramPromptContext (migration 0187) mapping a bot force-reply
prompt to the entry a free-text reply attaches to, keyed on
(chatId, promptMsgId) and scoped to the owning user. MoodEntry.source
already accepts the free-text TELEGRAM value, so no enum change is
needed.
