Fix encrypted day-log data loss and the stalled cumulative-measurement drain;
capture Withings sleep vitals and Oura VO2max; harden AI grounding across the
briefing, Coach, narrative, and status cards; full-page Coach with history and a
working mic; on-device lab OCR; preventive-care, labs, and settings polish; BP
warm/cold parity, a statement timeout, and a covering measurements index.
Coach new-chat surface with streamed answers and a token footer; lab-report OCR
ingestion with a mandatory per-row review; qualitative lab results; labs list
default, sort, and delete; VO2max on the dashboard with Oura ingest; preventive-
care date and due-status polish; faster condition journal; honest report
staleness; dashboard freshness on background sync.
One-shot prettier pass so the new format:check gate starts from a clean
baseline. Formatting only — no behaviour change. Generator-owned and
vendored artifacts stay untouched via .prettierignore.
The offline layer wrote far too much to disk and cleared it too rarely.
The query persister used a denylist (only auth/session/admin/tokens), so
every other family — coach, insights, illness, labs, mood, cycle — was
dehydrated to IndexedDB in plaintext; the service worker likewise
prefix-cached GET /api/insights, which serves decrypted Coach
conversations. Neither store carried an account marker and both were
wiped only on explicit logout, so a session that ended by expiry or a
401 left health data on disk for the next account on a shared profile.
Flip the persister to a strict allowlist (dashboard snapshot, per-chart
series, widget layout — the offline-dashboard set only) and stamp each
payload with the live account id, discarding on mismatch. Drop
/api/insights and /api/analytics from the worker allowlist. Wipe the
IndexedDB blob and the data/page caches on every session end — the
401/expiry redirect and the logout path both route through one helper.
The offline service worker cached allowlisted GET /api/* reads with
stale-while-revalidate, serving the cached pre-mutation copy first and
revalidating in the background. Online, a list fetched straight after a
create or update rendered the old (or empty) data until the next paint,
breaking read-after-write.
Switch the data branch to network-first: always fetch fresh from the
network online and refresh the cache behind it; fall back to the last
cached copy only when the network fails (offline). The offline fallback,
the allowlist plus auth/token/secret-body boundary, and the
release-versioned cache name are unchanged.
Add a regression guard to the cache-policy test that reads public/sw.js
and asserts the network-first wiring and the absence of the old
stale-while-revalidate handler.
An installed PWA opened offline rendered empty skeletons forever: the
service worker hard-excluded every /api/* path and there was no client
query persistence. Close both gaps for read value.
Service worker: add a stale-while-revalidate branch for an allowlist of
safe GET /api/* reads (dashboard snapshot + widgets, measurements,
medications, insights, analytics, version) in a release-versioned
healthlog-data cache. Two-layer refusal — a path deny guard for any
auth/token/session/login segment plus a body-level secret refusal for
hlk_/hlr_/sk- shapes and no-store responses — so a secret-shaped body or
an auth surface can never be persisted. Mutations stay network-only.
Client: add a dependency-free IndexedDB query persister that hydrates the
last successful reads before the first authenticated paint, build-version
and age gated, debounced on cache change, with an auth/session/admin/token
denylist. Cleared on logout alongside the SW page and data caches so a
shared device never leaks one account's data.
Offline banner now states it is showing last-synced data when a cached
snapshot is present. Bump release to v1.18.6.
Add categories (health, medical, lifestyle) and extend display_override
to allow minimal-ui as a fallback. Maskable icons were already present.
Screenshots are deferred until narrow + wide capture assets exist.
Self-hosters without an Apple Developer account rely on Web Push to the
installed PWA — there is no Live Activity or lock-screen widget to drive.
Make that path carry the dose lifecycle on its own:
- Stable per-slot tag. The medication dose-due reminder now sets a
`med:<id>:<iso-slot>` Web Push tag (medicationDoseTag), so a re-fired
reminder for the same slot coalesces instead of stacking, and a later
clear can target it.
- Clear-on-taken. When a dose is marked taken or skipped, push a
`type:"clear"` notification reusing that slot tag. The service worker
closes the matching pending reminder and refreshes the badge — the PWA
equivalent of ending a Live Activity. A snooze leaves the dose
outstanding and clears nothing. Wired into the single + bulk intake
routes alongside the existing APNs cross-device sync.
- App badge. The dispatcher carries a server-authoritative outstanding-
dose count; the SW reflects it via the Badging API
(setAppBadge/clearAppBadge), feature-detected and a no-op where
unsupported.
- The SW push handler honours requireInteraction for urgent events and
renotify so a re-fired reminder re-alerts.
Dose-due, preventive-care, and low-stock reminders already cascade to
Web Push when no APNs channel exists; tests pin that an APNs-less
instance still delivers.
Add the blood-glucose clinical panel with Nightscout, sleep debt and chronotype,
Polar and Oura over OAuth, reorder-aware medication supply and an invite
deep-link. Every new metric is computed once on the server and read the same way
on the dashboard, the coach, the doctor-report and the companion app, each behind
a still-learning gate. The coach now reasons from the new signals, mood and cycle
entry is one sectioned sheet, and previously-hidden wearable data surfaces.
Two daily-use fixes: the last-night hypnogram bar collapsed to its breakdown
for nights whose stages share an end instant, and the dashboard kept prompting
for a dose until a full reload after it was recorded. No breaking changes.
Read sleep, recovery and blood glucose from a single source on every surface —
dashboard, coach, doctor-report, CSV and FHIR exports, and the companion app —
so the displayed figure agrees wherever it appears. Sleep nights reconstruct
once with source de-duplication; WHOOP-native recovery is canonical and resolves
to one row per night; glucose converts to the user's unit at the point it is
served. Hardens the consent receipt path and deepens WHOOP sync with per-resource
cursors, targeted refresh and full backfill. Several displayed numbers become
correct-but-different — flagged in the changelog.
Coherence release: blood-pressure in-target unified on a labeled, thin-data-gated
90-day window across tile, health-score pillar and coach; the dashboard ring and
insights card built from one shared health-score input builder; the coach and the
doctor-report PDF/FHIR adherence drawn from the same dose ledger as the detail page;
and a shared entry-timestamp plausibility guard on measurement and mood. Several
displayed figures become correct-but-different (BP headline window, adherence).
App-wide service-worker registration (installable + offline, authenticated
pages kept out of the cache, logout wipe), era-correct historical dose-edit
attribution, CSV intake stock consumption, WHOOP late-workout ingest, web AI
consent-receipt minting, the layout partial-PUT section merge, the curated
mood-tag catalog, and a sweep of mobile header fixes.
Add three home-screen shortcuts (Add measurement, Today, Medications)
deep-linking into the app, each tagged `source=shortcut`. Add a 192×192
maskable icon alongside the existing 512 so adaptive launchers mask the
right size instead of downscaling the 512 or clipping the un-masked 192
"any" icon on circular masks.
No screenshots: the repo ships no real screenshot assets and fabricating
them is worse than the richer-install-dialog gain.
`public/sw.js` carries a `|| "..."` fallback literal used for `CACHE_VERSION`
when `importScripts('/sw-version.js')` is unavailable. The literal had drifted
to `v1.4.43`, four-plus minors behind `package.json`; in any environment where
the generated file is missing this keyed every cache to the stale version and
turned the activate-step eviction into a no-op — the exact bug the generator
was written to kill.
Extend the prebuild generator to rewrite the fallback literal in `sw.js` to the
current `package.json` version on every build, anchored on a
`/* @sw-version-fallback */` marker (the build fails loudly if the marker is
gone). The literal and the generated `sw-version.js` can no longer diverge.
The SW test now reads the fallback straight from the source so it tracks the
literal instead of hard-coding it.
With the service worker now registered for every user, the network-first
page cache sees every authenticated navigation. The everyday app routes
are client-fetch-only shells with no server-rendered PII, but the
`/c/[token]` clinician-share view renders health values straight into the
HTML and emits `no-store`. The page cache ignored the header and stored
it, so a revoked or expired share could still render back offline.
Gate `cache.put` in `networkFirst` on a new `isCacheableNavigation`
check: skip any response carrying `Cache-Control: no-store` (the
principled rule for any present or future server RSC that renders user
data) and skip the `/c/*` path outright as belt-and-braces. Ordinary
navigations still cache unchanged.
The score ring's bloom was clipped by the SVG's own viewport — the
drop-shadow sits on a child of the viewBox-filling arc — so the glow
never extended past the circle; the SVG now overflows visibly on every
host. The insight pill strip gains chevron buttons and wheel scrolling
so an overflowing row is reachable with a mouse. Safari favourites
rendered the transparent icon on a white plate; a flattened
apple-touch-icon and a maskable manifest icon fix both. The
time-of-day mood chart adopts the damped fill the weekday chart already
uses, eighteen delete confirmations move onto the destructive button
variant (one of them had the wrong text colour), five confirmation
dialogs gain pending states, the sources dialog stacks its primary
action on top on mobile, and the token form aligns input and button
heights.
The medication list fired one compliance request per card every 30
seconds, and each request scanned the medication's full intake history
and expanded the recurrence calendar five to six times. The endpoint now
mints bands once per request, serves the sub-windows from that single
ledger, bounds the event read to a year of selected columns and sits
behind a write-invalidated 15-minute server cache; the cards poll at
five minutes. The dashboard drops two redundant checklist queries by
reading counts from the snapshot, the BMI chart derives from the weight
series instead of refetching it, the detail page no longer serialises
behind the auth probe and seeds its query from the list row. Expensive
analytics reads gain a shared per-user rate limit, and the service
worker stops serving cross-version shells, enables navigation preload
and trims caches in one pass.
Swap the hand-authored body silhouette in the injection-site picker for a
clean, gender-neutral medical line-art figure with correct proportions
(arms to mid-thigh, head-to-body ≈1:7.5, separated legs, feet). The figure
ships as a small transparent raster (~8 KB) and is painted theme-aware: its
alpha drives an SVG mask over a currentColor rect, so the strokes take the
picker's text colour and tint correctly in light and dark.
Keeping the figure inside the SVG (rather than a CSS-masked sibling) means
it shares the dots' 100×200 viewBox, so alignment stays responsive by
construction. Recalibrate SITE_COORDS so the upper-arm, abdomen-quadrant
and thigh anchors land on the new figure's anatomy; the pointer overlay,
keyboard targets, recommendation ring, last-used marker and disabled-set
logic are unchanged.
The v1.4.38.3 `AppError` boundary reloads once when a stale shell
trips `ChunkLoadError`, but the reload only fires AFTER the user
hits a navigation that lazy-loads a missing chunk. Users sitting on
the dashboard or insights overview ride out the staleness until
their next click; some never click and the cached shell silently
drifts further out of date with every deploy.
Three layered fixes so the running app heals itself instead:
- `public/sw.js` now keys both `STATIC_CACHE` and `PAGE_CACHE` to
the app release tag (`v1.4.38.4`). The `activate` step already
evicts any cache name outside the current pair, so bumping the
string at release time guarantees the precached root HTML and the
precached `/_next/static/*` chunks from the previous deploy are
dropped on the next SW install.
- `next.config.ts` injects `NEXT_PUBLIC_APP_VERSION` from
`package.json` into the client bundle so the running shell knows
which release it was built against.
- New `<VersionPoller>` client component mounts inside `<Providers>`
and polls `/api/version` every 60 s. If the live version moves
ahead of the shell-baked version it unregisters every active SW,
wipes CacheStorage, and `window.location.reload()`s.
`sessionStorage` gates the reload to once per session so a
mid-deploy webhook race that briefly returns a stale image cannot
loop the page.
Consolidated hotfix landing the findings from a six-axis audit
covering mobile security, UX + accessibility, code quality + docs,
README + discoverability, web performance, and mobile-deep responsive
behaviour. None of the changes break the public API or the existing
data shape; every fix is additive and SAFE under the v1.4.34.x web
freeze. Full audit reports live in `.planning/round-audit-*.md`.
Security
- Password rotation now wipes API tokens + refresh tokens in the
same `$transaction` as session revocation. A stolen iOS Bearer no
longer survives a user-initiated password change or an admin reset.
- `/.well-known/` proxy bypass tightened to an explicit-allowlist
`Set`. Stale `/api/auth/codex/callback` PUBLIC_PATHS entry dropped.
- HSTS gains `preload`. Withings host removed from the global CSP
and gated to the integration's own routes.
- `getClientIp` warns once per process on `TRUST_PROXY_HOPS`/XFF
mismatch + exposes a tagged helper for tighter universal buckets.
- Service worker rejects off-origin notification-click URLs. Offline
fallback body switched to a locale-neutral icon. Manifest gains
`scope`, `id`, `display_override`.
UX + accessibility
- i18n leaks closed on Dialog/Sheet close-X, ChartSkeleton's loading
announcement, and the notifications-section breadcrumb.
- Focus rings on bottom-nav, the More overflow button, and the
mobile top-bar user menu.
- Tap-target floor: Input / NativeSelect / Select / DateTimeInput
switch to `h-11 sm:h-10`.
- Admin chip-strip auto-scroll-into-view (matches v1.4.33 settings).
- List-page subtitles visible on mobile.
- Insights empty-state CTA vocabulary normalised so the link opens
the right measurement form (was silently failing for
BODY_TEMPERATURE / BLOOD_GLUCOSE / PULSE).
Mobile-deep
- `viewport.themeColor` reacts to light/dark mode.
- TopBar + Coach FAB reserve safe-area-inset-top / -bottom for
notched iPhones.
- Sonner toaster switches to `theme="system"`.
Code quality
- `SESSION_SECRET` dropped — the env var was documented as required
but never read by code. Three secrets, not four. Self-hosters
upgrading can delete the existing line.
- `toJson<T>()` helper consolidates seven Prisma JSON-cast sites.
- `db-compat.ts` gains a header docstring naming it the
schema-bootstrap path.
- Passkey response types adopted from `@simplewebauthn/server`;
`any` + eslint-disable pragmas drop out.
- Zero-TODO CI gate added at `.github/workflows/no-todo-markers.yml`.
Documentation + discoverability
- README rework: How-it-compares matrix, Apple Health + AI Coach
promoted to standalone Key-Features bullets, status block, latest
release + GHCR badges, OpenAPI pointer, three-secret Quick Start.
- openGraph + twitter cards now carry `images` and a
`summary_large_image` Twitter card.
- GitHub repo metadata: description tightened from 290 to 156
chars + keyword-front, `homepageUrl` flipped from a personal
tenant to the demo site, six generic / PII-adjacent topics
swapped for six high-intent ones.
- Five new user-facing docs: `docs/self-hosting/getting-started.md`,
`docs/self-hosting/reverse-proxy.md`,
`docs/integrations/apple-health.md`,
`docs/integrations/withings.md`,
`docs/integrations/ai-providers.md`.
- `docs/README.md` clarifies the docs tree as internal playbooks
vs the user-facing `docs.healthlog.dev` site.
Long-overdue prettier sweep; prettier had drifted vs. checked-in code
across ~130 files (mostly long-argument line-break wrapping in TS and
table-padding in markdown). Pure formatting — no semantic changes —
and required to clear the v1.4.6 release gate's `pnpm format:check`.
