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.
Check a newly chosen password against HaveIBeenPwned through the k-anonymity
range API: only the first five hex characters of the SHA-1 digest leave the
host, the suffix is matched locally, and Add-Padding hides the bucket size.
A confirmed match is rejected so a fresh credential is never a known-breached
one; the check fails open, so an unreachable HIBP never blocks the operation.
Covers registration, password change, and admin reset. Existing passwords are
never retroactively blocked at login.
Also lands the six-locale strings for the password-breach notice and the
account-security surfaces that follow.
Account deletion and the keep-account data reset now demand a recent
second-factor re-verification for accounts that have a second factor
active; single-factor accounts are unaffected and keep the typed-
confirmation-only contract. The gate runs through requireFreshMfaIfEnrolled,
which is cookie-only by construction — a Bearer transport for an MFA-enrolled
account cannot satisfy step-up and surfaces the auth.stepup.required envelope
so the UI can launch a re-verification flow.
When a password is accepted for an account with a confirmed TOTP factor, the
login route no longer mints a session or token. It creates a single-use,
~5-minute MfaChallenge (the opaque ticket is stored only as a hash) and
returns HTTP 200 with data:null, error:null and meta.mfaRequired + mfaTicket +
methods. The client completes the login at POST /api/auth/mfa/verify with the
ticket + a TOTP or recovery code, receiving the exact same token bundle the
password path issues, with the session stamped second-factor-verified.
- The ticket is claimed once, atomically, only after the factor verifies, so
two concurrent submissions can mint at most one session; no session ever
exists before factor two.
- Wrong codes increment the ticket attempt counter and burn it at the cap
(throttle, not an account lock); the anonymous verify surface is also
rate-limited per IP.
- meta.mfaRequired is returned only after a valid password and the
invalid-credentials response is identical regardless of MFA state, so an
attacker without the password cannot enumerate MFA.
- The session/token tail is extracted to login-response.ts and shared by both
the password path and the verify path, keeping the transport contract
identical. OpenAPI registers the verify endpoint, the MFA management
endpoints, and the mfaRequired login variant.
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.
Add requireFreshMfa(maxAgeSeconds) and requireCookieAuth alongside
requireAdmin. Both resolve through getSession() only, so a Bearer token can
never satisfy them — the same structural boundary requireAdmin relies on, not
a softenable runtime check. requireFreshMfa passes only for a cookie session
whose Session.mfaVerifiedAt is within the window and whose user has an active
second factor; otherwise it throws StepUpRequiredError (401 +
meta.errorCode "auth.stepup.required") so the client can launch a
re-verification flow.
createSession now accepts an optional mfaVerifiedAt stamp so a session minted
behind a completed second factor records its freshness.
Wrap GET /api/measurements/:id through shapeMeasurementNotes like the list,
create, and update paths already do, so the encrypted note column is decrypted
into notes and the raw ciphertext is stripped from the response. Harden the
rotation-coverage guard to require both the field literal and the model
delegate, so a same-named encrypted column whose table is not rotated is caught.
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.
Standardise the labs marker subtitle to text-xs across both the compact list
and the card grid, and build the localized name->slug lookup map once per
locale instead of re-scanning the catalog seeds per group on every render.
Add relative to the mobile section strips in the settings and admin shells so
the active chip's offsetLeft is measured from the strip, giving an exact
horizontal scroll target.
Drop the orphaned insights.sleep.headlineCaption and headlineCaptionSuffix
keys from all six locales; nothing references them after the sleep headline
removal.
Hide the copy button on insecure-context (plain-HTTP) self-hosts where the
Clipboard API is undefined: a new SSR-safe useClipboardSupported() detector
mirrors the speech-synthesis hook so the button is absent rather than
error-toasting on tap.
Stop the per-message action row compressing below the 44px touch floor on
narrow phones: the icon buttons keep their tap size (shrink-0 + min-w-11) and
the row wraps instead of shrinking the up-to-six targets to ~30px.
Surface an icon-only action row below each message, sharing the row with
the hover timestamp: muted until the bubble is hovered or focused on
pointer devices, and always visible on touch where there is no hover.
User turns get Copy; assistant turns get Copy, Read-aloud, a thumbs-up /
thumbs-down feedback pair (wired to the existing per-message feedback
endpoint), and Try-again. Copy strips inline chart tokens from assistant
prose so they are never pasted. Try-again resubmits the user turn that
produced the reply as a fresh turn, leaving the composer untouched.
Read-aloud only set the utterance language and let the browser fall back
to its default voice, which on most systems is a legacy compact engine
that reads robotically. Enumerate the installed voices, rank them for the
active locale (prefer enhanced/premium, Siri, Microsoft Natural/Online,
Google, and an exact lang-region match; penalise known compact engines),
and assign the winner with a natural rate and pitch. The voice list loads
asynchronously, so subscribe to voiceschanged and re-rank lazily; when no
voice beats the legacy default, fall back gracefully to prior behaviour.
The history search rendered as a thin, short strip that read as an
afterthought. Give it the app's standard full-width input height and
padding so it matches the standalone conversations page and looks
intentional.
Shorten the composer placeholder across all locales to a short, inviting
one-liner and clip the placeholder pseudo-element so a longer hint can
never wrap to a second line inside the single-row composer on a narrow
phone. The textarea value still wraps and auto-grows for real typing.
Surface a short, factual subtitle under every catalog-linked lab marker on
the Labs page, mirroring the descriptive line the Insights overview carries
under its metric headings. The text states what each biomarker measures,
sourced from the seed catalog via a new labs.catalog.desc.<slug> i18n map in
all six locales.
A reading's analyte resolves back to its catalog slug by a case- and
whitespace-insensitive match against the localised catalog name; free-text
markers with no catalog match carry no subtitle rather than a fabricated one.
Rendered in both the compact list view and the card/tile view.
Fixed-pixel chart bands ate roughly half the screen when a small phone
was rotated to landscape. Swap the brittle heights for viewport-relative
clamps so the chart envelope holds its previous size on desktop and
portrait but shrinks toward a floor on short landscape viewports. Covers
the overview trends-row slot and the mood distribution, weekday, and
time-of-day charts (with matching skeleton heights). Chart series and
styling are untouched; only the container heights flex.
The Sleep view led with an average-per-night headline card that repeated
the same figure and label already shown in the average-sleep tile within
the sleep-rhythm grid row below it. Remove the leading card and let the
tile carry the readout; the stage-distribution bar and duration trend
chart stay in place.
The long single-word labels (de "Benachrichtigungen") clipped their last
character at the tile edge on a 320 px phone. Trim the grid gutters and the
tile padding/gap to hand each label more horizontal room, and cap the bottom
sheet at max-w-md, so the label wraps cleanly onto a second line instead of
running off the tile. Tile height stays uniform.
The Theme sub-trigger inherited the shared sub-trigger padding (py-1.5,
no min-height) while every sibling row carries min-h-11 py-2, so the
Theme row sat a few pixels shorter and the menu read as unevenly spaced.
Match the item height on this instance only, leaving other dropdowns'
sub-triggers untouched.
Code-review and design follow-ups before the v1.22 cut. No behaviour change
beyond the items below.
Coach / insights:
- Coach SSE route: a non-provider error raised inside the open producer (e.g. a
DB failure persisting the reply) now records on the wide event and forwards to
GlitchTip instead of masquerading as a provider outage; it still surfaces an
error frame since the stream is open.
- Lab ↔ outcome correlations: hedge faint-tier pairs ("a faint hint, if
anything … too small to lean on") so the narrated confidence never outruns the
effect, matching the daily engine.
- Reminder sweep: mint the plan-review reminder and clear the plan's reviewDate
in one transaction so a half-applied write can't duplicate the reminder.
- Fold the two raw provider-fallback runners onto one shared chain walker.
Design / accessibility:
- Lift sub-44px tap targets to the 44px mobile floor (suggested-action card,
Coach bubble affordances), brighten the resting timestamp clock for non-text
contrast, and route the lab chart height through the shared constant.
- Replace ad-hoc arbitrary type sizes with the scale token and static size-11
icon buttons with the named icon-lg variant.
- Settings: add the missing About card-header descriptions, normalise the
low-stock numeric widths, and relax the notification-status rows from nested
cards to a divided list.
Housekeeping:
- Drop three unused exported types (and the now-orphaned source const), re-stamp
v1.21.5 comments to v1.22, and register the live-judge eval harness as a knip
entry so the script-only module resolves.
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.
Route the composer seed questions through i18n so a German user no longer
gets an English opener when tapping Ask the Coach from a metric page or an
insight card. Replace the relative timestamp on the briefing and per-metric
cards with a freshness label that shows the time only for today, drops it for
yesterday, and renders a locale date honouring the user's date-format
preference for older entries. Render the briefing paragraph, the per-metric
and score assessments, and the period narrative through the shared paragraph
helper so longer prose shows real paragraphs instead of one run-on block.
Adds the insights.coach.seed.* and insights.updated* keys (English + German).
Feed the user's own usual blood-pressure range — the median plus or minus
MAD band, computed from the readings already in the snapshot — into the Coach
context with a clause to quote those bounds verbatim, so a band is never
invented from window means. Thread the stored first name into the prompt and
surface it sparingly on roughly one turn in three, never as a rote greeting.
Add the context-layer rule that names the relevant context before a
suggestion, a single-chart-token allowance that works on every provider, and
a per-turn opener hint.
Wire the already-shipped suggested-action SSE frame to render: the streaming
hook collects it and the message thread shows the action card, mirroring the
reminder-suggestion path. Extend the eval golden set with band-verbatim,
chart-token, and no-overclaim cases, and pin a red-team case proving the
chart-token syntax cannot smuggle a dose past the outbound screen.
Replace the fixed three-beat assessment skeleton with a menu of moves the
model orders freely, and reframe the daily briefing from per-signal
enumeration to a verdict-first read that weaves the few salient signals into
one associative story. Score cards now name both the helped and the hurt
contributors, translate the band into a forward read for the day, and close
on one grounded nudge; the deterministic fallback gains the same band-meaning
sentence so provider-less and demo accounts read as well.
Add a hash-seeded opener-archetype rotation (deterministic, testable) so
consecutive cards and days no longer open the same way, a day-rotated sampling
seed for the period narrative in place of the fixed reference seed, and a
shared paragraph formatting contract. Add a score-number grounding gate and
extend the briefing grounding allow-set to the glucose, labs, preventive-care
and workout aggregate blocks so real figures can be cited without opening the
gate. Gate the daily score warm on an input fingerprint so a quiet day skips
the model call.
Add unit coverage for the closed when-grammar and `---REMEMBER---` capture
(propose-free active write, recall-only note, malformed drop, per-user cap),
the closed action-card allowlist (off-list and bad-interval rejection, no
auto-apply), the daily sweep (due flip, plan-review mint, undecryptable
skip), and the routes (owner-scoped no-IDOR 404, field-by-field build, the
off-allowlist 422, and the module gate).
Add a "Your reminders" panel under Settings → Coach that lists the stored
reminders, highlights the due ones, and gives the user view, confirm,
done/dismiss, and delete control over their own memory. Light the Coach
launcher dot when a reminder is due, alongside the existing nudge signal.
Add the generic confirm-card component for the suggested-action frame: a
plain-text preview with a localized per-action heading and a single confirm
tap that posts the validated params to the build endpoint.
Translate the new copy in English and German.
Add the management surface for the reminder memory: list, create, confirm,
done/dismiss, and soft-delete, every query scoped to the session owner with
the same no-IDOR posture as the plans routes (a cross-user or unknown id is
a 0-count no-op, never a leaked existence). The note is the only writable
field; timing is resolved server-side from the closed grammar.
Add the confirm endpoint behind the generalised action card. It switches on
a closed action-type allowlist and builds each entity field-by-field from a
server-resolved spec: a preventive-care reminder whose schedule comes from a
closed interval catalog, or a reminder note. It never auto-applies, and the
allowlist excludes any medication or clinical change.
Regenerate the OpenAPI contract for the new routes.
Capture the casual "remember this / remind me about X" utterance the Coach
used to drop. The model emits a provider-neutral `---REMEMBER---` sentinel
that the chat route strips inline on EVERY turn — so a short conversation,
where the request usually happens, no longer waits for the long-chat memory
worker. The note is the user's own explicit request, so it is stored
silently as active; a validated closed grammar (ISO date, relative +Nd/+Nw,
or a context cue) sets the trigger, and a malformed block is dropped.
Surface the stored reminders two ways. A snapshot recall sub-block injects
near, overdue, and already-surfaced reminders so the Coach references them
unprompted next turn. A daily sweep flips overdue reminders to due and
mints a one-off review reminder from a plan whose review date has passed,
finally activating the plan review-date column. In-app surfacing only here;
push delivery follows later.
Also generalise the propose-then-confirm action card: a closed
`---SUGGEST-ACTION---` allowlist (a preventive-care item or a reminder note)
rides an additive SSE frame. Nothing is created until the user confirms.
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.
Thread the rolling early-detection pass and the labs -> outcome pass through the
correlations route and the coach correlations reader, both of which already
build the same daily series. The route response gains an optional `emerging`
block (recent-window pairs not yet established, flagged provisional) and a
`labCorrelations` block; the coach reader gains matching `emerging` and
`labDrivers` fields. Regenerate the OpenAPI contract for the new response shape.
The daily briefing's always-on feature payload carried only the core vitals,
mood, sleep, steps and medication compliance, leaving four captured domains
invisible to it. Add four blocks to the aggregated features:
- Labs: recent flagged biomarkers (out-of-range or trending vs the prior
reading). Retired markers are excluded; qualitative results stay neutral with
no fabricated verdict.
- Preventive care: due and overdue items off the server-authoritative next-due
date, so an overdue screening can prompt an early nudge.
- Workouts: a provider-agnostic count, duration and distance aggregate over the
trailing windows (the briefing previously saw activity only as step counts).
- Glucose: the present-and-trend block the other vitals carry, where glucose
previously reached the briefing only as a single signal-of-the-day row.
The three extra reads are scoped to the wide briefing window; the tight
snapshot window that already carries its own context skips them. Every block is
omitted when its domain is empty rather than emitting zeros, and user-entered
labels are sanitised before they reach the prompt.
Add a rolling 14-21 day early-detection pass to the FDR correlation engine
so an emerging shift (illness pulling HRV and sleep down together) surfaces
before the 180-day retrospective scan accrues the n>=20 it needs. The recent
pass re-runs the same engine over the trailing window with a lower paired-day
floor, a tighter Benjamini-Hochberg target, and a no-faint effect bar, then
drops any pair the retrospective scan already established so a pattern is never
reported as both established and emerging.
Extend the curated behaviour x outcome matrix with three clinically meaningful
links: medication adherence -> next-day blood pressure (systolic and diastolic,
the latter previously never a candidate channel), sleep as a behaviour
(poor sleep -> next-day mood / HRV), and a separate point-vs-window labs ->
outcome pass (each draw against the contemporaneous outcome mean) since sparse
lab draws cannot meet a daily-lag floor. Every pass keeps FDR control, the
effect-size floor, and shrinkage; thin data degrades to absent, never a
fabricated link. All associations stay descriptive, never causal.
The bottom-right launcher opened a blank new chat on an unread proactive
message instead of the thread the Coach wrote. Return the owning
conversation id from the nudge-status endpoint, have the launcher open
/coach?c=<id> on the unread path, and stamp the same deep link on the push
metadata so the notification lands in the exact conversation rather than
relying on a most-recent heuristic.
Activate the dormant chart-token render path for the Coach: an allowlisted
metric:<TYPE> token in a settled assistant turn mounts the self-fetching
HealthChart for the user's own series, gated on the turn's grounded
provenance so a metric the reply never saw never renders and no data is
fabricated. Add a read-aloud toggle backed by the browser Speech Synthesis
API (no dependency, no egress) and a hover/tap timestamp tooltip on each
message bubble. Render message text through the shared paragraph helper.
Add a shared, pure ProseBlocks helper that splits trusted plain text on
blank lines into <p> blocks and single newlines into <br>, with no markdown
library and no dangerouslySetInnerHTML. A catalog-whitelisted linkifier turns
grounded /learn/<slug> references into safe anchors via learn-more-link;
unknown slugs stay plain text. Rewrite StreamedProse to be streaming-safe:
completed paragraphs settle while only the growing tail animates word by
word.
Clicking a type on the measurements list now drills into that metric's
insights sub-page when one exists, falling back to the existing
?type= filtered list when it does not. A reverse type-to-slug map backs
the navigation, preferring the dedicated single-metric page so an
ambiguous type resolves correctly (PULSE to pulse, not blood-pressure;
WEIGHT to weight, not bmi). No API change.
resolveInsightsLayout merged any default tile a saved layout did not
enumerate as hidden, so a late-added tile such as steps (introduced in
v1.12) was force-hidden on every read of an existing or iOS-synced
layout and its nav pill never appeared, even with step data present.
Appended tiles now inherit the default visibility instead, matching the
fresh-account default; the per-tile data floor still keeps an empty
metric out of the nav.
