The cookie was the Session row's cuid. cuid is built for collision-
resistant identity across distributed writers, not for unguessability —
it encodes a millisecond timestamp and a process-local counter and never
touches a CSPRNG. A session cookie is a bearer credential and has to be
unguessable, so it now carries 32 random bytes and only the HMAC of that
value is stored, matching how api_tokens and refresh_tokens already hold
their secrets.
Compatibility is passive, and deliberately so. A backfill cannot help:
the cookie already sitting in a browser is the cuid, and nothing we
generate server-side can be pushed into it — backfilling would sign
everyone out at deploy. Upgrading a row in place on first use loses to
the parallel requests a single page load fires: each mints its own
secret, one write wins, and the losers cannot re-emit the winner's
secret because only a hash is stored, so the browser can end up holding
a value the row does not honour. Instead, rows minted before the column
keep a NULL token_hash and stay resolvable by id, and are denied the
sliding-expiry extension so they drain within the 30-day session
lifetime. Every login from this release forward is on a secret at once,
and an id stops authenticating the moment its row holds one.
Note for operators: API_TOKEN_HMAC_KEY now also keys session cookies, so
rotating it signs browser sessions out as well as invalidating tokens.
It is already Core-required, so no deployment gains a new prerequisite.
A transient database fault during logout must still clear the session
cookie; record the delete failure on the wide event instead of throwing
before the cookie is cleared, so a user can never stay authenticated
after logging out. Remove the batch measurement future/past instant
refine: cumulative HealthKit rows carry an end-of-day endDate that is
legitimately hours ahead for the current day, and a whole-array parse
would 422 the entire sync. Note the workout batch's deferred Withings
path must write its source directly.
The incident forwarder stripped the query string but not path-segment
secrets from the reported URL; route it through the same redaction the
message and stack already use. Several delete-and-swallow paths caught
every error as the expected unique/absent-row case, masking real
failures on security-notification, logout, and integration-disconnect
paths and the Telegram reply-consume guard; narrow each to the specific
Prisma code and let real failures surface.
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.
