E1. Two halves of one correction. `.env.example` still said backup objects
older than BACKUP_RETENTION_DAYS are pruned, which no code does, so a
self-hoster reading that file alone still expected the worker to keep the
bucket tidy. It now carries the same sentence as the production example.
And that sentence overreached in the other direction: "the worker never
deletes an object" is not true of `_healthcheck/<ts>.bin`, the 1-byte key
the Test-connection button writes and then deletes. The delete swallows
its own failure, so an operator who granted exactly the three documented
actions leaves one orphan per press and is never told. Both files now say
"a BACKUP object", and name the one key and what happens without
DeleteObject on that prefix.
BACKUP_S3_REGION and BACKUP_RETENTION_DAYS are both on the compose whitelist and
both read by the backup job, but the example file listed neither — so an
operator following it had no way to learn that the region defaults to auto, or
that the retention number is what the bucket's own lifecycle rule has to be set
to, since the worker never deletes an object itself.
The environment: block is a whitelist. Compose substitutes ${VAR} from .env
at compose-up, so a value set there looks configured, but a variable the block
does not name never reaches the Node process and the default stands silently.
Twenty-eight variables were in that state: DEMO_MODE, the four LOG_* knobs and
the three LOKI_* shipping vars, DATABASE_STATEMENT_TIMEOUT_MS, four retention
and alerting windows, TELEGRAM_WEBHOOK_SECRET, NIGHTSCOUT_PRIVATE_ORIGINS,
three OAuth callback overrides, both Open-Meteo endpoints, four AI knobs,
three APNs key-source vars, and DASHBOARD_SSR_PREFETCH.
APNS_KEY and APNS_KEY_FILE are the sharpest of them: .env.production.example
and the env manifest both document a precedence chain of APNS_KEY_B64 before
APNS_KEY before APNS_KEY_FILE, and only the first arrived.
Each is documented in .env.production.example in its neighbours' style. The
VAPID section's note claiming those three names are absent from the whitelist
is corrected; they have been on it since v1.17.1.
Two findings from the docs truth audit, both operator-facing.
scripts/restore-backup.ts wrote the decrypted backup, which is health
data in plaintext, with the process default file mode, leaving it
world-readable on the operator's disk while it sat there. It is now
written 0o600.
TRUST_PROXY_HOPS is read from the environment to size the trusted
X-Forwarded-For chain, but it was absent from the compose environment
whitelist, so an operator value in .env never reached the container and
was silently ignored. It now rides all four surfaces: the compose
whitelist, both env examples, and the manifest that pnpm check-env
reads.
The document-AI actions (read/index, extract, suggest, summarise) shared a
hard-coded 6/hour bucket that lied twice: the 429 said "try again in a few
minutes" while the window is an hour, and several failure paths burned a
slot before any provider was dispatched.
- DOCUMENT_AI_LIMIT_PER_HOUR configures the shared per-user ceiling
(default 6, clamped 1-1000), wired end to end: compose environment
whitelist, .env.production.example, env manifest, operator docs.
- INSIGHTS_RATE_LIMIT_PER_HOUR joins the compose whitelist and manifest;
it was documented but never listed, so an operator value could not reach
the container.
- The 429 mirrors the bucket's reset instant into meta.retryAt (plus the
existing X-RateLimit-Reset header); the client derives "try again in
about N minutes" from it in all six locales, with a plural-aware key.
- A slot is consumed only when a request actually reaches the provider (or
the local index/echo work): malformed bodies, unreadable originals,
refused consent, and exhausted daily budgets refund the charged slot via
a window-scoped refundRateLimit primitive. Consistent across all four
routes sharing the bucket.
Cover the new MAXMIND_LICENSE_KEY route in the self-hosting guide as the
first of the three ways to get the offline databases (fetch, mount, bake),
and note that the monthly runtime refresh keeps a keyed host current on its
own. Add the variable to both env examples and to the env-check manifest so
the optional group lists it.
Refs #659
AUDIT_LOG_RETENTION_DAYS is not only enforced, it is published: the
shared-access panel prints the window under the activity list, and the dialog
that ends somebody else's access states how long "who entered what" stays
answerable. Both read the value the server resolved. It was missing from the
compose environment: whitelist and from both example files, so an operator who
set 90 got 365 told to every user, in a sentence about their own data.
That block is a whitelist and Compose substitutes from .env regardless, which
is what makes the variable look configured while never arriving — the same
shape as the session-cookie flag in v1.5.2. A guard now covers the three places
an operator meets such a variable, and its control leg found that the cookie
flag itself is still absent from the production example. Documented there too.
The runtime has always read GEOLITE2_DIR, but the variable was absent
from the compose `environment:` whitelist, from both env examples, and
from the docs. A variable that is not on that whitelist never reaches
the container even when the operator's `.env` sets it, so the override
existed in code and was unreachable from the documented path.
Put it on the whitelist, document it in both examples and the manifest,
and add `docs/self-hosting/geolite2.md`: fetch the databases with a free
MaxMind account, mount the directory read-only, point the variable at
it. The compose file carries the bind-mount line commented out beside
the app service.
The admin notification told the reader to set MAXMIND_LICENSE_KEY in
this repository's Actions secrets — something nobody running the
published image can do, about a fallback that sends their sign-in
addresses to a third party. It now names the mount, names the online
provider it is actually querying, and links the runbook. Six locales.
It also no longer claims the carrier column stays empty; the online
tier has filled the carrier from the ISP field since v1.25.8.
A blank GEOLITE2_DIR now resolves to the default instead of the process
working directory: compose substitutes an unset variable to the empty
string, which is not nullish.

The web OIDC flow ends in a session cookie the Bearer-transport native
client cannot consume, so on an OIDC_ONLY instance the iOS app had no
sign-in. Add a native leg: the app opens the login URL with
client=native and its own PKCE S256 challenge inside an in-app browser;
the callback resolves identity exactly as before, then mints a one-time
handoff code and 302s to the fixed compiled-in scheme
healthlog://oidc-callback (or hands back the existing MFA ticket when
the account has a second factor). The app exchanges the code plus its
PKCE verifier at POST /api/auth/oidc/native/token for the standard
native token bundle.
The return address is a compile-time constant — no redirect_uri
parameter and no env allowlist, so the open-redirect / scheme-hijack
class is removed by construction. The native flag and app challenge
travel only inside the AES-256-GCM state blob, so a network attacker or
the IdP cannot flip a web login into a native one. The handoff code is
256-bit CSPRNG, HMAC-hashed at rest, 90-second TTL, single-use via a
guarded consume; a failed PKCE check burns it. A replay of a consumed
code revokes exactly the pair the first exchange issued. The token pair
never rides a URL; only the opaque code or the MFA ticket do. The SSO
login can never satisfy requireFreshMfa step-up — the transport is
Bearer and step-up is cookie-only.
Adds the OidcNativeHandoff model (migration 0252), the token-exchange
route, a daily cleanup sweep, and the OpenAPI entry.
Token verification: jwtVerify now carries a closed asymmetric algorithm
allowlist (RS256/PS256/ES256/EdDSA — an HMAC alg would let anyone with
the client secret forge identities) and a 60 s clock tolerance for the
usual self-host drift between IdP and app box. The JWKS fetch — jose's
own, outside safeFetch by design — is disciplined instead by pinning
the jwks_uri host to the configured issuer's host byte-exact and
passing the same 15 s timeout safeFetch defaults to. requirePublicHost
stays deliberately unused on this surface: LAN/Tailscale-only IdPs are
a legitimate topology and the issuer is operator config, not user
input.
Discovery: the issuer comparison now tolerates exactly one trailing
slash on either side (a recurring IdP/operator mismatch); token
verification still matches the provider-sent issuer byte-exact.
State cookie: the cookie is set under Path=/api/auth/oidc but was
deleted without a path — RFC 6265 keys cookies by (name, domain,
path), so the deletion never matched and the single-use blob survived
its whole TTL. Every delete now repeats the exact path, via a shared
constant.
Also: the IdP error code recorded in the wide event is whitelisted
against the closed OAuth error-code set (unknown values collapse to
"other"); the status route drops an unreachable try/catch and a
duplicated annotate; the passkey conditional-UI autofill stays unarmed
under OIDC_ONLY (passkey login is a server-enforced dead end there);
env-manifest gains the three optional OIDC_* tuning vars; the env
example notes why the issuer should be HTTPS.
Adds an OpenID Connect relying-party login path (PKCE authorization-code
flow) against a single env-configured identity provider — additive to
password/passkey login by default, with an operator opt-in (OIDC_ONLY,
enforced server-side on every auth route) to disable them entirely.
First-time sign-in auto-provisions or links an account by verified email.
Closes an open redirect in the post-login `next` parameter (both the new
OIDC path and the pre-existing password/passkey flow shared the same
backslash-normalization bypass) by resolving the target through a real
URL parse and comparing origins instead of a prefix check.
The recurring no-briefing day had a chain of causes, closed end to end:
Every failure path in the nightly pregenerate + the comprehensive generator
now annotates a queryable cause (several classes — features-error,
payload-too-large, aborted, generator-failed — previously bumped a counter
with zero trace). A failed nightly warm enqueues one bounded retry ~45
minutes later (singleton per user, existing budgets apply), so a transient
provider hiccup heals before morning. A cached payload that carries NO
briefing no longer satisfies the 24h POST short-circuit nor the
unchanged-content hash gate — a once-stripped briefing could previously
block its own regeneration indefinitely. The card surfaces the omission
reason persistently (grounding strip, generation failure, not attempted)
with a forcing retry.
Documentation corrected against code truth: Withings credentials are
per-user (the documented env path never existed; the dead example entries
and manifest rows are gone, and WITHINGS_WEBHOOK_SECRET is now actually
whitelisted in compose — stock deploys could never deliver it); the classic
Fitbit portal no longer accepts new registrations; the backup-restore
example no longer mints a fresh encryption key and uses pnpm dlx tsx; the
TLS guide describes the real client model (two CA-level SPKI pins,
any-match, leaf renewals need no build); scaling/admin references fixed;
the operator-shared subscription provider is documented.
The Local provider speaks the standard JSON wire: response_format by default,
one self-healing fallback per endpoint when a server rejects it (dialect
cached per base URL) — LiteLLM, OpenRouter, vLLM, LM Studio and plain Ollama
all work from the same form, and the form + provider docs now say so. A
gateway that shims a Claude-family model behind a synthesized tool call is
parsed from the tool-call arguments instead of yielding silently empty
insights.
The insight token budget is configurable (INSIGHTS_MAX_TOKENS, default 2500,
clamped 500-8000) and unified across all six call sites; a reply cut off
mid-JSON returns a distinct truncation error instead of a generic parse
failure. A briefing withheld by the number-grounding check now says so on the
card instead of pretending nothing was generated. The provider test button
answers 4xx with a bad_request category instead of claiming the endpoint was
unreachable.
Sleep repair follow-up: measurements carries a second full unique index — the
natural key (type, measured_at, source, sleep_stage) — so a key-format
migration could tombstone the old rows while their re-keyed replacements
collided with that index and were silently dropped (live incident: a
full-history re-sync erased a user's sleep). Planned creates now run a
natural-key rescue probe: a match, live or tombstoned, is updated in place —
fresh value, the new externalId, deletedAt cleared. A rescue-probe failure
holds the watermark so nothing is lost past the overlap.
The bundled Skia x64 build (document thumbnails, scanned-PDF rasterization)
uses AVX2 instructions; on an x86-64 host without them — Celeron/Atom-class
NAS CPUs, pre-2013 Xeons, VMs masking CPU flags — the first canvas call is an
uncatchable SIGILL that kills the process and crash-loops the container (live
incident: a Synology DS1520+, exit 132 ~18 s after every boot, reported with
kernel traps and the correct root cause in hand).
The renderer is now gated on a one-time CPU-feature check before the module
ever loads: linux/x64 requires the avx2 cpuinfo flag; arm64 and non-Linux are
unaffected; unreadable cpuinfo fails open. Behind a closed gate, thumbnail
generation and PDF rasterization take their existing fail-soft paths (vault
shows type icons; PDFs read as text) and the boot-time thumbnail backfill
skips enqueueing. NATIVE_CANVAS=off|on overrides detection, documented in the
env example and whitelisted in compose.
Add Strava as a per-user BYO-OAuth workout source, mirroring the shipped
WHOOP/Oura/Polar pattern. Strava caps every new app at single-player mode, so
each self-hoster registers their own app and pastes the client id/secret into
Settings (falling back to a shared env app). Strava is a workout source only —
it exposes no daily metrics and no training-depth analytics are derived.
- Schema (migration 0233): per-user encrypted client id/secret + access/refresh
tokens, plaintext athlete id, incremental cursor, and backfill marker on
`User`; `STRAVA` added to `MeasurementSource`.
- Token model follows Oura's reactive-refresh-on-401 with a compare-and-set on
the stored refresh ciphertext, because Strava rotates its refresh token on
every refresh.
- Client over safeFetch: authorization-code + refresh, activity list + budget-
aware per-activity detail (for calories/HR), honouring the 200/15min cap; each
activity maps to one `Workout` row. Activity name/description stay in metadata
as data, never surfaced or interpolated.
- Dedup reuses the existing source-agnostic two-layer picker: `STRAVA` slots
into the workout ladder below the device-native wearables and above
MANUAL/IMPORT, so an Apple-Watch + Strava twin collapses to one canonical row.
- Poll-cohort hourly sync (:17) + self-converging boot backfill, wired into the
integration-sync registrar. Webhook deferred.
- OAuth routes (connect/callback/credentials/disconnect/status/test) with signed
state, cross-account re-auth rejection, and a surgical `www.strava.com`
connect-src gated to the Strava surfaces.
- Settings card + consolidated status envelope entry; env + compose whitelist;
i18n across all six locales.
- Garmin: no direct connector is possible (business-partner-only). Add
docs/integrations/garmin.md documenting the Apple Health / Google Health
Connect path and Garmin's withheld proprietary scores, cross-linked from both
platform docs, plus a non-connector info note in the Connections panel.
Regenerate docs/api/openapi.yaml for the new `STRAVA` MeasurementSource value.
A self-hoster can set IP_GEO_ALLOW_INSECURE=true alongside an http:// URL to
use a free HTTP-only provider — the free ip-api.com endpoint is HTTP-only (its
HTTPS form needs a paid key) but its geolocation is often more accurate and it
carries the ISP. The default stays HTTPS-only with ipwho.is; plain HTTP is
refused unless the operator explicitly opts in, since the looked-up IP then
travels unencrypted over the server's own egress. Whitelisted in compose and
documented in the env example.
Add the opt-in Environment module (default off), its Settings surface (home
location search, travel overrides, backfill, with Open-Meteo attribution), the
gated API routes (overview, home, geocode, travel CRUD, backfill), the nightly
pg-boss fetch job with a lookback window plus on-demand backfill, the query
keys, six-locale strings, and the regenerated OpenAPI. The module performs an
outbound weather fetch tied to a coarse location, so it ships dark and the user
turns it on deliberately; off means no job, no row, no egress.
The local AI provider's private-host opt-in is read from the environment but
was missing from the compose environment whitelist, so the value never reached
the container. Add it (and document it in the env example) so a self-hoster can
point the local provider at an internal Ollama / LM Studio host.
Add the optional FITBIT_REDIRECT_URI to .env.production.example (BYO-key shape,
derives from NEXT_PUBLIC_APP_URL) so check-env documents it. Rename the
settings-card copy from "Google Health" to "Fitbit" across all six locales now
that the transport is the classic Fitbit Web API.
The ipwho.is default rejected server-side egress with a 403 on the free
plan, which the resolver swallowed as a clean miss, so the admin
login/audit overview rendered "—" for every session. Switch the default
online provider to ip-api.com (the parser already accepts its
status/countryCode shape) and surface a non-ok HTTP status (403/429/5xx)
as a wide-event warning instead of returning null silently, so a future
provider rejection is visible.
Whitelist TRUST_CF_CONNECTING_IP, IP_GEO_LOOKUP_URL and
IP_GEO_LOOKUP_DISABLED in the compose environment block and document them
in .env.production.example so a Cloudflare-fronted deployment can store
the real visitor IP rather than the edge address.
Document the new Generate keys button in notifications.md as the easiest
Web Push setup path, demoting the CLI to an alternative. Note that
clientManaged medication-reminder suppression is an iOS-app-only contract
so a PWA-only operator does not go hunting for a web toggle.
Add the VAPID env-var names and APNS_KEY_B64 to .env.production.example
(the loader and APNs sender read them, but the example omitted them),
both as commented placeholders, with a note that Web Push needs no Apple
account and that these vars are not in the compose whitelist.
Add a Backup and restore section to getting-started.md: a local pg_dump
one-liner and the load-bearing warning that the ENCRYPTION_KEYS /
ENCRYPTION_KEY must be backed up alongside the dump or the encrypted data
is unrecoverable, cross-linking the off-host backup and key-rotation
runbooks. Add troubleshooting entries for the compose env-var whitelist
and pull_policy: always.
Add the webhook + email Settings copy and the admin notification-health
panel labels across all six locales. Add the SMTP_* operator vars to the
env manifest (all-or-none: HOST + PORT + FROM enable the channel,
USER/PASS optional), to .env.production.example, and to the docker-compose
environment whitelist so an operator's .env values actually reach the
container.
Connect an Oura account over the Cloud v2 API: an authorization-code OAuth
flow (shared app from OURA_CLIENT_ID / OURA_CLIENT_SECRET) on the same signed
state machinery as Polar. Unlike Polar, Oura issues refresh tokens; the sync
refreshes reactively on a 401, rotating and re-encrypting both tokens, and a
403 stays a hard reauth rather than a refresh.
An hourly poll-cohort job maps daily readiness to RECOVERY_SCORE, sleep to
per-stage durations plus efficiency / HRV / resting heart rate / respiratory
rate, and daily activity to steps and active energy — all tagged source OURA,
idempotent on (userId, type, source, externalId). Readiness flows through the
canonical recovery ladder above the computed proxy. Settings gains a connect /
disconnect card. Tokens are never logged or returned; every egress goes
through safeFetch.
Connect a Polar account over AccessLink v3: an authorization-code OAuth
flow (shared app from POLAR_CLIENT_ID / POLAR_CLIENT_SECRET) backed by a
stateless HMAC-signed state token doubling as an httpOnly cookie for CSRF.
The callback verifies the signature, expiry, provider binding, and the
byte-exact cookie match, then encrypts the access token plus member id onto
the user row.
An hourly poll-cohort job maps Nightly Recharge recovery, sleep stages,
and daily activity to canonical measurements tagged source POLAR, idempotent
on (userId, type, source, externalId). The recovery band feeds RECOVERY_SCORE
through the canonical ladder, which now ranks native readiness above the
computed proxy. Settings gains a connect / disconnect card. Tokens are never
logged or returned; every egress goes through safeFetch.
Published manifests are now cosign-signed keyless with a documented
digest-pinning path, a lefthook pre-commit runs gitleaks over staged
changes, responses opt into a credentialless embedder policy, the
deploy webhook can require a fresh timestamp, and a monthly drill
decrypts and parses the newest offhost backup so a broken key or format
surfaces before an emergency does.
Blood-pressure fixtures in the in-target integration suite were copied
from live readings; they are now synthetic with the same in/out split so
every assertion holds. Hard-coded operator hostnames move behind env vars
(DEPLOY_LOGS_URL, HEALTHLOG_PROD_URL), the codex client identifies via
the public repository URL, the OpenAPI servers entry points at a neutral
example host, and remaining workflow, docs and comment references to the
operator's instance or working notes are generalised. The compose
whitelist also gains DEPLOY_WEBHOOK_SECRET, which was missing and made
the deploy webhook unusable on compose installs.
openssl rand -base64 24 can emit URI-reserved characters (/, +, =). Since POSTGRES_PASSWORD is interpolated unescaped into DATABASE_URL, such a password breaks the connection URL and blocks boot. Switch every documented example to openssl rand -hex 32 (URL-safe, 256-bit).
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.
(cherry picked from commit cdb88cd77b88aec71ad2f21caf2b15c185dfc01e)
Connect mints the state nonce into the WhoopOAuthState ledger and redirects
to the WHOOP authorize page; callback verifies the nonce (atomic
delete-first consume, four distinguished reason tags), exchanges the code,
fetches the WHOOP profile for the user id, persists the encrypted
WhoopConnection, and enqueues the self-converging history backfill.
The webhook handler rate-limits per source first, verifies the
WHOOP_WEBHOOK_SECRET path segment, then verifies the HMAC-SHA256 body
signature over the raw bytes (timestamp + body, timingSafeEqual, stale
timestamp reject) before any work. Valid *.updated enqueues the matching
per-resource sync; *.deleted soft-deletes (workouts hard-delete, no
soft-delete column). Unknown users return 200 to stop retries.
CSP gates api.prod.whoop.com to the WHOOP settings surface + /api/whoop/*;
the webhook path joins the public-path allowlist and the path-secret redact
registry. Env wiring adds WHOOP_WEBHOOK_SECRET + WHOOP_REDIRECT_URI to the
compose whitelist and .env.production.example.
Raise the per-export administration ceiling from 1000 to 5000 (~3.5 years
at four doses a day) and resolve it from FHIR_MAX_MEDICATION_ADMINISTRATIONS,
bounded 1..50000 with a fallback to 5000 on an unset or out-of-range value.
The windowed-then-capped newest-first behaviour and the honest-truncation
narrative are unchanged; this only raises the ceiling so it bites far less
often. Add the var to the compose environment whitelist and the production
env example so it reaches the container and check-env stays green.
It is a build-time NEXT_PUBLIC_* var (inlined into the client bundle),
default ON, disabled only by rebuilding with the var set to false. Note
the build-time nature in .env.production.example and getting-started,
and keep it out of the compose runtime whitelist where it would mislead
operators.
iOS-operator-blocking hotfix for REG-11 — Home dashboard tile renders
neither chart nor latest value for BP / Puls / Körperfett when the
most recent reading is older than 7 days. Root cause was in
`/api/dashboard/summary` SQL gates; `latestIn7d` + `sparkBuckets` both
required `measured_at >= sevenDaysAgo`, which returned empty for
sparse accounts, leaving the iOS tile with `latestValue: null` +
`sparkline: []` to render from. Detail-screen
(`/api/measurements/series?kind=…`) escaped because of its broader
window.
Server-side changes:
- `latestIn7d` → `latestEver` (drops 7-day filter; DISTINCT ON returns
latest reading EVER per type, bounded at N_metrics rows).
- `sparkBuckets` rewritten via ROW_NUMBER() OVER (PARTITION BY type
ORDER BY bucket_start DESC) so the trailing N daily buckets per
type render regardless of age, bounded at SPARK_DAYS × N_metrics.
- BP + Pulse metrics.push gated on `latest || allTimeCount > 0` like
BodyFat already is — accounts with zero readings ever no longer get
empty placeholder tiles.
- 4 new regression tests in summary/__tests__/route.test.ts cover
sparse accounts, zero-data accounts, within-7d guards.
