Every raw-SQL clock read against a timestamp column without a zone now
writes NOW() AT TIME ZONE 'UTC', so passkey and login challenges, rate
limits, provider pauses, coach usage stamps, tombstone and measurement
windows no longer pass through the session time zone even where the
per-connection pin cannot apply. The regression-window bounds stay naive
UTC timestamps instead of being turned into timestamptz. A structural
guard keeps bare NOW() / CURRENT_TIMESTAMP out of raw SQL outside a short
list of timestamptz targets. The integration test sets the database
default to Europe/Berlin and drives challenge claims, session expiry, the
native sign-in handoff freshness check and the rate-limit window through
the app's client, plus the challenge claim through an unpinned client.
Self-hosting docs describe the pin for an existing or shared Postgres.
Stored times are UTC in timestamp columns without a zone, and Postgres
reads now(), CURRENT_TIMESTAMP and offset-free timestamptz parameters
through the session time zone. On a database whose default is not UTC
every expiry check ran off by the offset. The Prisma pool, pg-boss, the
lock and the maintenance connections now send TimeZone=UTC as a startup
option, or SET it on connect when the startup options are disabled for
a pooler. A boot check reads SHOW TimeZone and warns on anything else.
The statement timeout and, since v1.42, work_mem reach Postgres as the
libpq options startup parameter, which PgBouncer refuses unless it is in
ignore_startup_parameters. A host behind it could drop the string by
setting the timeout to 0; work_mem is now always sent, so that no longer
worked. DATABASE_SESSION_OPTIONS_DISABLED sends no session settings,
documented in the example env, the env manifest, the compose whitelist
and the scaling guide.
The nightly folds soft-deleted every raw Apple Health sample they folded
into an hourly or daily stats row and kept it for 75 days. Nothing ever
read those rows as deletions; they only held a re-upload of the sample
off, and they were most of the measurements table and its indexes.
Ingest now refuses such a re-upload directly: a raw sample of a dense or
mean type, old enough to have been folded, whose hour or day a live
stats row covers, is a duplicate with reason folded_window. The batch
route and the Apple Health export import apply the same rule. With that
in place the dense retention and the daily-mean consolidation delete the
raw rows outright, and a new compaction-tombstone-purge job removes the
backlog: 5,000 rows a batch, one account at a time under the restore
lock, a short pause between batches, resumable because the predicate is
idempotent, queued at every boot and continuing itself while it makes
progress. A person's own deletions are never in its predicate. The sync
feed leaves compaction tombstones out and a restore does not write them
back; all three classify through the same function.
The batch route answers an exact re-sent sample without a transaction:
one read over the batch's sample ids, live or deleted, decides what the
reconciler would have decided, at the same point in the loop, so every
status, reason, counter and the cross-source merge stay as they were. A
batch of duplicates only no longer queues PR detection, a reminder sweep
or the detection audit row. Caches are evicted only for a foreground or
manual sync or a batch that wrote a hand-entered reading, and marked
stale otherwise; the targets cache follows the same split.
Also:
- POST /api/admin/maintenance/measurements queues VACUUM (ANALYZE) and a
REINDEX INDEX CONCURRENTLY per index, largest first, on a connection of
its own; it refuses while the purge runs, drops invalid leftover copies
and stops at the first failed rebuild. Runbook in docs/ops.
- The pure volume queues keep their finished jobs for 96 hours instead
of seven days, never less than the failure window plus a day.
- work_mem is set per app connection from DATABASE_WORK_MEM (16MB), also
when the statement timeout is disabled.
- The PR-detection fallback tick re-scans only accounts whose readings
or workouts changed since the previous tick.
- Type discovery for the status refill walks the live-rows index as a
loose index scan instead of grouping every live row.
- The host metrics chart polls every five minutes, like its sampler.
- The batch route records per-type HealthKit arrivals.
A production build loads src/lib/db.ts once per server bundle, and the
client was only parked on globalThis outside production. The running
process held three clients: about 28 MB of query-compiler state each on
a heap capped near 520 MB, and three pg pools each sized to the full
per-process connection budget. Park the client on globalThis in every
environment so each copy of the module resolves the same one.
The 15s default cancelled the live-aggregate analytics fallback on a coverage
miss over a large account (Postgres 57014), surfacing as a 500. Sixty seconds
still bounds a runaway query well before it can starve the pool while leaving
headroom for the heaviest legitimate read.
Without a statement timeout a single stuck query or lock wait holds one of
the 20 pool slots indefinitely; enough of them permanently exhaust the pool
and every DB-backed route stops serving. Apply statement_timeout and
idle_in_transaction_session_timeout (default 15s, env-overridable, 0 to
disable) at connection establishment so every pooled session is bounded.
Correct the stale pool-sizing comment: production max_connections is 200,
not 100, and the web and worker containers share the one Postgres.
A typed apiFetch wrapper owns the envelope unwrap, the ok-check and the
error read for every client call — two hundred call sites across the
app migrate onto it and a lint rule keeps raw api fetches out for good.
The legacy timezone helpers fold into the tz module and test fixtures
drop personal names.
Eleven touch-disjoint waves landed on develop plus a six-axis QA
reconcile round before tagging. See CHANGELOG.md for the user-facing
prose; this commit message documents the wave + report inventory for
release-management traceability.
Waves shipped (each with a phase report under .planning/):
- phase-W-POOL-v1440-report.md — p-limit(4) wrapper around the
analytics 15-way fan-out + pg.Pool max raised 10 -> 20. Closes the
v1.4.39 empirical-trace finding #1 (Prisma pool starvation).
- phase-W-DELETED-v1440-report.md — 11 reader-tier helpers + 3
integration contracts close audit Critical Finding #3 (soft-delete
invisibility) across dashboard, analytics, summaries, rollup tiers,
and the Coach snapshot path.
- phase-W-INSIGHTS-v1440-report.md — mood-rollup swap on the three
/api/insights/{features,targets,cards} routes plus the
compliance-rollup hook gap closure for bulk-projection mints; the
post-QA reconcile patch closes the six remaining measurement.findMany
sites in the cluster that still leaked tombstoned rows.
- phase-W-INFRA-v1440-report.md — rollup helper umbrella consolidation
under src/lib/rollups/* with zero orphan re-exports; lint, typecheck,
knip, and 93/93 rollup tests green post-restructure.
- phase-W-RSC-v1440-report.md — per-tile Suspense boundaries plus the
queryKey factory-bypass walker test (extended to comparison/ in the
reconcile pass).
- phase-W-PRIVACY-v1440-report.md — bilingual /privacy page with 17
paired-section tests pinning the 9 SB-3 disclosure requirements.
- phase-W-AASA-v1440-report.md — /.well-known/apple-app-site-association
endpoint pinned to S8WDX4W5KX.dev.healthlog.app with app-ID parity
assertions guarding against split rotation.
- phase-W-APNS-NOTIFY-v1440-report.md — MEDICATION_REMINDER
time-sensitive APNs payload (priority 10 + interruption-level)
scoped via a parameterised test that pins all 6 other event-types
do not bypass Focus. AP-2 .p8 install gates real delivery.
- phase-W-CONSENT-v1440-report.md — AI consent receipts CRUD with
append-only invariant pinned in test; revoke-then-regrant leaves
both rows; idempotent DELETE returns 200 + receipt: null.
- phase-W-WMY-WIRE-v1440-report.md — three previously-dead WMY readers
(week/month/year) wired through summaries-slice and
health-score-fast-path with a linear-composability parity test
pinning the cross-consumer routing contract.
- phase-W-GHOSTS-v1440-report.md — ~1 177 lines of dead code removed
across 9 atomic commits; startOfUtcDay + wallClockInTz consolidation
eliminates a sibling-drift risk; knip whitelist trimmed to three
files pending follow-up.
QA reconcile patches applied per the v1.4.40 QA round (six reports
under .planning/round-v1440-QA-*-findings.md):
- senior C1 — dashboard-suspense-boundaries regex aligned with the
post-W-INFRA Thread 2 userTimezone-local lift.
- senior H1 — soft-delete filter added to the six remaining
insights measurement.findMany sites.
- specialist H1 — Promise.allSettled around bulk-projection
compliance recompute on both /api/medications/intake and
/api/dashboard/summary.
- ux H1 — compare-toggle migrated to queryKeys.dashboardWidgets
factory; walker test extended to src/components/comparison/.
- security M1 — consent artefact 64 KB cap enforced via
Buffer.byteLength (UTF-8 bytes, not UTF-16 code units).
Quality gates green at tag: pnpm typecheck, pnpm lint, pnpm knip
--include files,dependencies,binaries,unlisted, pnpm test --run
(4726 passing / 1 skipped). Tests 4525 -> 4726 unit + 1 skipped over
the v1.4.39 -> v1.4.40 span.
User-facing prose: see CHANGELOG.md.
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.
HealthLog — personal health-tracking PWA with weight, blood pressure,
pulse, mood tracking, medication compliance, Withings integration,
