Changelog

[1.4.22] — 2026-05-10

Added

• Per-target sparkline + Δ-vs-last-month caption on the Targets / Zielwerte page. Each <TargetCard> grew a 30-day inline SVG sparkline beneath the range bar plus a localised "Δ −2.3 kg vs. last month" caption. The API ships points30d and deltaVsLastMonth per target; both null when either window has fewer than 3 readings so cold-start accounts don't paint a misleading flat trace. BMI piggybacks on the weight series so its sparkline shares the range bar's y-axis.
• Sticky section navigation above the Insights hero. A pinned strip (Allgemein / Blutdruck / Gewicht / Puls / Stimmung in DE; General / Blood Pressure / Weight / Pulse / Mood in EN) lifts the section tabs above the hero so they stay visible during scroll. Active section tracks the highest-intersection observed entry; aria-current, focus-visible ring, and motion-reduce gating ship from day one.
• Comparison-overlay as a single global preference under Settings → Dashboard. The on-surface <CompareToggle /> retired from /insights; the canonical picker has lived in Settings → Dashboard since v1.4.16 phase B8 and every chart already consumed it. Two surfaces for the same concept violated the no-split-Settings rule.
• Collapsible evidence disclosure under each Coach assistant message. Numbers move out of the prose into a ---KEYVALUES--- … ---END--- sentinel block that the route parses out server-side and renders as a "Worauf bezieht sich das?" / "What I'm looking at" <details> disclosure under each assistant turn. Closed by default, hidden when no key-values came back. Hard caps on the sentinel (1 KB payload, 8 lines max, per-line Zod) so a prompt-injection attempt can't grow the persisted envelope.
• User avatar parity with the Coach avatar. The Coach drawer's user-side bubble used a smaller initials avatar than the Coach's gradient one. The user avatar now reuses the existing gravatarUrl field from /api/auth/me at the same dimensions as the Coach avatar; initials fall back when no Gravatar is configured.

Changed

• Coach prompt rewrite — warm, motivational-interviewing tone with prose-first responses + evidence collapsible. PROMPT_VERSION ratchets 4.20.2 → 4.22.0 (first minor-digit bump in v1.4.x). The Coach used to open every reply with a number — clinical, database-cursor energy. The new persona is "warm, neugierig, zurückhaltend": a partner sitting alongside the user, not pushing data. Numbers move into the collapsible evidence block; the prose reads like a real conversation. Persona + sentinel land together because either alone is incomplete.
• BP-in-target headline re-anchored to the last-30-day window. Fourth attempt at this metric. v1.4.19 routed the headline to allTime to fix the algorithmic 50/50/50 pin; v1.4.22 re-anchors to windows.last30Days?.pct and surfaces all-time as a sub-row, because v1.4.19's fix was emotionally wrong — the headline became the slowest-moving aggregate possible, punishing a user who put in real recent work. The tile also gets a synthesised trend arrow (slope from 7d/30d delta), a 7-day-trend chip, and a comparison-overlay caption.
• "Muster" renamed to "Zusammenhänge" (DE) / "Patterns" renamed to "Relationships" (EN). The picked-bucket-of-correlations row read like an autopsy. The new label sits closer to what the row actually shows. Picked "Zusammenhänge" over "Trends" because the row directly above already uses Trends.
• Onboarding redirect for users with null onboardingCompletedAt moves to server-side enforcement in proxy.ts. The previous post-hydration redirect inside <AuthShell> useEffect produced a brief dashboard flash on incomplete onboarding. The proxy runs in the Edge runtime so the auth routes mirror onboardingCompletedAt into a non-httpOnly hl_onboarding cookie; the proxy short-circuits before hydration. Tampering only skips a UX hint and never bypasses a server check.
• setOnboardingPendingCookie folded into createSession(). Issuing a session without onboarding state used to require two call sites to stay in sync; the helper now takes onboardingPending as a required parameter so the contract is type-impossible to break.

Fixed

• Raw metric:<TYPE> token leaks in recommendation prose. <RecommendationCard> text is now wrapped in stripChartTokens(). The leak traced to a single missing call on the recommendation path; chart tokens never belonged in user copy.
• DE locale componentMood, componentBp, componentCompliance rendered English nouns in the German bundle. Four Health-Score component labels normalised to Stimmung, Blutdruck, Einnahmetreue, Gewicht. The i18n-integrity test pins the contract.
• Admin / API tokens horizontal scrollbar at desktop + iPad-mini viewports (5th attempt). A live Playwright probe confirmed whitespace-nowrap on the date <td>s was the residual culprit. The two classes are gone; date + time wraps to two lines on narrow viewports. The earlier four fixes had targeted the wrong layout layer.
• Sentinel-only / malformed ---KEYVALUES--- block. When the model emits a sentinel-only or malformed envelope, the fallback now produces a polite invitation ("I'd like to look at this with you — could you share which window you want me to focus on?") instead of surfacing the raw marker. A new integration test covers the empty-prose-after-strip branch.
• BD-Zielbereich tile delta math period-aligned with the comparison window. The tile's compareDelta was subtracting bpInTargetPctAllTime while the caption said "vs last month", which produced numbers the caption couldn't justify. It now subtracts bpInTargetPctPriorMonth / bpInTargetPctPriorYear to match. Two new bp-in-target unit tests + two insights-polish guards.
• Coach drawer settings cog removed. The cog was a dead button in v1.4.21; per-user prompt-tuning is deferred to v1.4.23. No dead buttons in this release.
• Coach disclaimer pinned at the bottom of the message thread. Clinical-adjacent UI must not gate the disclaimer behind a chevron tray; the disclaimer now stays visible at the bottom of the message thread on every viewport, and the rail-footer duplicate kept for desktop redundancy.
• hl_onboarding UX-hint cookie now SameSite=Strict. A cross-site request couldn't usefully exfiltrate the cookie (no auth value, only an onboarding state flag) but Lax was still over-permissive. Strict aligns with the cookie's same-site-only consumer.
• PUBLIC_PATHS exact-match guard against future subroute prefix bypasses. /onboarding is now exact-match + explicit-subroute, not a startsWith check. Two new proxy guards pin the contract.
• targets/route.ts daily buckets keyed in Europe/Berlin. The targets sparkline was the last analytics surface still bucketing in UTC, which produced a one-day-off trace for users in CEST. berlinDayKey() lifted to a shared src/lib/analytics/berlin-day.ts helper; four new DST + UTC- midnight edge-case unit tests.
• Streaming bubble vs persisted-twin race window. The 150ms grace window suppresses the persisted twin while the in-flight streaming bubble is still rendering, so the thread never paints two copies of the same reply for a frame.
• Sticky section navigation a11y polish. aria-current on the active section; focus-visible ring on keyboard navigation; motion-reduce honoured for smooth-scroll; the glow-bleed fixed via bg-background/95 backdrop-blur; the mobile cliff tightened from scroll-mt-28 to scroll-mt-16 so the strip no longer eats the heading at 280px viewports.
• BP tile mobile density at <sm. All-time + delta now collapse into one secondary line on small viewports; the full layout returns at >=sm.

Refactor

• createSseStream shared helper extracted from the chat route. Preparation for v1.5 iOS streaming endpoints, which will reuse the SSE primitives. Three unit tests pin sync, async, and throw paths. Source: src/lib/sse/create-stream.ts.
• <TokenStatusBadge> extracted from desktop + mobile api-token surfaces. The badge logic was duplicated verbatim in two layouts; one component, two consumers.
• Five simplify apply-yes items in one commit. canSubmit collapse, weekly-report <Button> dedup, and three smaller cleanups identified in the W5 simplify pass.

Operational / hygiene

• Coolify image-digest auto-deploy. Instructions for the one-time UI-toggle ("Watch image registry for new digests") live at .planning/coolify-auto-deploy-howto.md. Future releases should drop the host-side retag fallback the moment the toggle is on.
• 191 maintainer-name references in src/ source comments swept (FX carry-over from v1.4.20). Test fixtures kept as opaque test data.
• DE+EN bilingual CHANGELOG entries (v1.4.14 + v1.4.15) normalised to English-only. Per the English-only voice rule.
• CLAUDE.md filename retired (FX carry-over) so the filename is no longer AI-vendor-specific; CONTRIBUTING.md reference updated. AGENTS.md stays for multi-agent compatibility.

Deferred to v1.4.23

See .planning/v1422-backlog.md for the full carry-over list. Highlights: sentinel parser malformed-enum hardening (Sr-M5); analytics-route unbounded findMany paging; targets-route 7-pass sparkline coalesce; CoachDrawer key={prefill} controlled-prop refactor (Sr-HIGH-4); per-user prompt-tuning surface; medication_schedules.days_of_week schema-drift cleanup.

Deferred to v1.5 (iOS push)

See .planning/phase-W5-v1422-product-lead-review.md for the full v1.5 plan. Headline: iOS native client + Apple Health ingest contract (HRV, Sleep, Resting HR, Steps, BodyFat, Glucose); per-metric APNs alerts; OpenAPI spec drift CI gate; Coach extension for the new measurement types (PROMPT_VERSION 4.22.0 → 5.0.0).

[1.4.21] — 2026-05-10

Fixed

• Daily Briefing regenerate produced an empty card. The /api/insights/generate route was still calling the legacy getInsightsSystemPrompt, which returns the v1.4.5 schema and never asks the model for a dailyBriefing block. Re-runs from the hero strip therefore stored a payload with no briefing and the card painted its empty state forever. The route now uses getStrictInsightsSystemPrompt(locale) so the v1.4.20 ground rules apply to manual regeneration too. Cached legacy blobs still parse — every new schema field is optional with passthrough().
• Duplicate streaming bubble after the assistant reply landed. After SSE done the streaming hook keeps streaming.content populated to support the in-flight render path, then fires a TanStack invalidate that pulls the persisted assistant message into conversation.messages. The thread therefore rendered the reply twice until the next send reset cleared it. The render path now suppresses the in-flight bubble as soon as the persisted twin lands, keyed on streaming.messageId.
• Settings cog overlapped by the drawer's close-X. Radix Sheet paints its default close-X at top-4 right-4, which visually swallowed the cog in the right-edge button cluster. The cog moves to the left header zone (next to the gradient avatar) and a pr-12 / sm:pr-14 padding rule keeps the New-chat button out of the close-X area on narrower viewports.
• Suggested-prompt chips below the 36px touch target. Chips rendered at 28px which fell short of the WCAG-AA target-size guideline. Padding bumped to land on a 36px hit area.

Changed

• Coach context now carries day-level readings instead of aggregates only. buildCoachSnapshot folds in a timeline.recent block (one row per UTC day for the last 14 days, each tagged with weekday) and a timeline.weekly block (ISO-week buckets covering the rest of the analysis window). Systolic and diastolic pair into a single BP row per day; half-measured days drop so the model never fabricates a complement. Per-day medication-adherence rows draw from MedicationIntakeEvent. The EN and DE Coach system prompts gain a DAY-LEVEL READINGS section instructing the model to answer day-specific or weekday-specific questions out of timeline.recent with date + weekday citations, acknowledge missing days plainly, and fall back to timeline.weekly for older windows. Token cost per Coach turn rises from ≈190 tokens (aggregates only) to ≈3000 tokens for a full-scope snapshot. The new scope picker is the relief valve.

Added

• Per-source + per-window scope picker on the Coach sources rail. The sources rail grew real per-source checkboxes (BP / Weight / Pulse / Mood / Compliance — 36px touch target, 60% opacity when excluded) and a window selector (last 7 days / 30 days / 90 days / all-time). The drawer owns the scope state and forwards picked scope through useSendCoachMessage to the chat request body. Toggles reset to the all-source last-30-days default each drawer open. The scope payload only ships when the user has narrowed away from the default — server can tell "no opinion" from "intentionally narrow". A single-source last-7-days narrowed turn lands around ≈600–700 tokens.

[1.4.20] — 2026-05-10

Added

• Insights redesign — hero strip, Daily Briefing, Suggested Prompts. /insights opens with a new hero strip that pairs a time-of-day greeting and primary action row with a strip of suggested-prompt chips. Below the hero, a Daily Briefing card surfaces an AI-generated paragraph plus three keyFindings drawn from the last 24-hour window. Suggested-prompt chips drive the Coach drawer with prefill text.
• AI Coach drawer with streaming chat and encrypted persistence. A right-side drawer over /insights hosts a streaming Coach conversation. POST /api/insights/chat is an SSE endpoint that walks the existing AI provider chain and emits token → provenance → done frames. Conversation history persists across sessions; GET /api/insights/chat, GET /api/insights/chat/[id], and DELETE /api/insights/chat/[id] round-trip the history rail. Source-chip provenance attaches to every assistant turn (metric, window, n-count — labels only, never raw values). The drawer mounts via the hero strip's "Ask the coach" button or any suggested-prompt chip. Three-column layout on lg+ (history rail · message thread · sources rail), full-screen single-column on mobile with chevron- button trays for the rails.
• Correlation discovery — 3 hypothesis cards. A new <CorrelationRow> between Daily Briefing and the Advisor card surfaces three pre-defined hypotheses (BP × medication compliance, mood × pulse, weight × weekday) with Pearson r + Fisher-z confidence interval. Surfacing gate: n ≥ 14 paired observations and p < 0.05; below the gate the cards stay collapsed.
• Trends row with AI annotations. A new <TrendsRow> mounts alongside the correlation cards. Each annotation is a short AI-generated callout tied to a specific date in the analyzed window; the BP timeline gains storyboard markers at the same positions via an additive annotations[] prop on <HealthChart>.
• Weekly Report at /insights/report/[week]. A newsletter-style printable surface with Summary / Going-well / Worth-watching / Tips / Data-quality sections. window.print() export via Tailwind print: variants; the hero strip surfaces fresh weekly reports with Read · Share · Export PDF actions (Web Share API with clipboard fallback).
• Personal Health Score (composite 0–100). A deterministic <HealthScoreCard> panel renders alongside the hero strip on lg+. Score weights: 30% BP-target rate + 20% weight-trend alignment + 20% mood stability + 30% medication compliance. Three bands (green ≥75, yellow 50–74, red <50). "Ask the Coach" CTA opens the drawer with a score-aware prefill.

Changed

• PROMPT_VERSION 4.19.0 → 4.20.2. Three controlled bumps across B1 → B3 → B4 carry GROUND RULES 8–11 covering the new schema fields. aiInsightResponseSchema extended with optional dailyBriefing / trendAnnotations / weeklyReport / storyboardAnnotations / healthScore blocks; legacy v1.4.19 cached payloads still parse because every new field is nullable
  • optional.
• Branch + release model. CONTRIBUTING.md documents a long-lived develop branch as the daily target and main as release-only. End users follow main / latest tag; contributors branch from and PR into develop. The mirror page at /contributing/branch-model/ on the docs site explains the same flow for would-be contributors.
• Repository hygiene. New .github/CODE_OF_CONDUCT.md (Contributor Covenant 2.1), three issue templates, a pull-request template, expanded Dependabot scopes (npm + github-actions + docker), and complete package.json metadata (description, license, homepage, repository, bugs, keywords).

Fixed

• Coach SSE idempotency replay no longer returns null. The idempotency wrapper double-read the body on replay; the streaming route now caches the original SSE response correctly. Also repairs the dead error-frame branch and stabilises useSendCoachMessage opts.
• Streaming assistant text announces to screen readers. The message thread now has aria-live="polite" on the in-flight bubble so token-by-token streams reach assistive tech.
• Coach drawer width capped on lg+. Drawer no longer hits 1080 px on common laptops; sources rail moves to a tray below xl.
• Hero glow z-isolation under sticky nav. The hero radial glow used to bleed through the sticky section nav on scroll.
• Suggested-prompt chip touch target ≥ 36 px. Was 28 px, below the project's interactive-control floor.
• "Generate weekly report" hero button enabled. Previously rendered disabled; now wired to the report route.
• buildCoachSnapshot bounded to 90 days. The Coach context helper used to walk every measurement on every turn; capped at 90 days to keep token cost predictable.
• formatRelativeTime consolidated. Three near-identical copies in the insights surfaces collapsed into one shared helper.

Security

• Coach conversation persistence is encrypted at rest. New Prisma models CoachConversation, CoachMessage, and CoachUsage (migration 0035_coach_conversations_v1420) store message bodies under AES-256-GCM via the existing crypto.ts. Provenance lives in metricSourceJson as labels only (metric, window, n-count) — never raw values. GDPR cascade-on-user-delete wired through the FK chain.
• Prompt-injection refusal pattern. The Coach SSE route runs every incoming message through an EN+DE refusal scanner that short-circuits prompt-injection attempts and obvious off-topic asks before the provider call.
• Per-user daily token budget. CoachUsage ledgers (user, UTC-day) → tokens; the 25 000-token cap (≈13 turns for a heavy user) prevents runaway spend on shared provider keys.

Deferred to v1.4.21

• 22 MED + 16 LOW + 4 simplify-apply-maybe items from the multi- reviewer Phase-D pass. Highlights at .planning/v1421-backlog.md include: senior-dev call to consolidate the duplicated Pearson / linear-regression maths layer; refactor the <CoachDrawer key={prefill}> state-reset shortcut into a controlled prefill prop; transactional recordSpend(); refusal accounting + lexicon expansion.

Deferred to v1.5

• iOS native app, Apple Health integration, and per-metric APNs alerts. Strategic plan at .planning/phase-D-v1420-product-lead-review.md.

[1.4.19] — 2026-05-10

Fixed

• BD-Zielbereich headline now shows independent values for 7T / 30T / total. The big number used to be identical to the 30T sub-value because /api/analytics aliased bpInTargetPct to last30Days?.pct. computeBpInTargetWindows() now returns a third allTime window and the route routes the headline through it, so the three numbers can legitimately differ across the three windows.
• Charts mobile header no longer breaks the layout on Pixel 5. The card header switches to a mobile-first stack below sm (title + chips on row 1, range tabs + cog right-aligned on row 2 with flex-nowrap) so the tabs always own a single row down to 280 px (Galaxy Fold compact). Bucket-aggregation chips and comparison captions hide on mobile to free horizontal budget.
• Charts x-axis tick density unified across every chart wrapper. New src/lib/charts/x-axis-density.ts helper + useViewportWidth hook caps visible ticks at 4 (Fold) / 6 (Pixel 5 / iPhone 12) / 8 (small tablet) / 10 (desktop). Wired into HealthChart, MoodChart, MedicationComplianceChart, and ComplianceLineChart, so the medication chart no longer overloads with one tick per day.
• /admin/api-tokens table no longer triggers a horizontal scrollbar at any viewport (4th attempt). Truncate-with-tooltip pattern on token-name, username, and permission badge, plus table-fixed + colgroup widths on the desktop table. Mobile falls back to the existing card list, now walked end-to-end by an e2e regression.
• Spurious mini-scrollbar on /admin/feedback tab strip. The shared tabsListVariants primitive picked up overflow-y-hidden so the strip no longer paints a 1 px slither below the tabs.
• /insights raw metric: blood_pressure_sweet template leak. STRIP_TOKEN_REGEX widened to [A-Za-z0-9_]+ so lowercase template remnants are scrubbed from AI prose; the uppercase render allowlist (PARSE_TOKEN_REGEX) is unchanged.
• AdminShell hides the collapse button on single-section pages. No more dead "Einklappen" affordance when the route only exposes one section.
• Mobile Sys/Dia badge enum mismatch on blood-pressure rows. CRITICAL from QA — the badge enum on mobile measurement rows decoded the wrong key. Fixed before tag with a TDD guard.
• 6 CRITICAL + 21 HIGH copy / consistency / a11y findings from the quality-of-life audit. Time-window range strings now respect the active locale, login overview filters out non-auth events, the date / datetime input pair forwards lang so the native picker uses the user's locale, raw enum badges are humanised, audit-action labels are localised and link back to the row, achievement titles no longer insult the user, and a long tail of admin / settings copy consistency.

Changed

• Settings → Integrations status displays consolidated. Withings and Mood Log cards now share a single canonical <IntegrationStatusPill> chip top-right ("Connected · 12 min ago" with locale-aware relative-time bucketing). The redundant v1.4.15 banner trio (connected / last successful / last attempt) and Mood Log's bottom-of-card "letzter Sync" line are gone; both cards now carry a divider between header and body for visual symmetry. Actionable error text stays as a compact inline alert above the action row.
• Comparison overlay control removed from the dashboard. The toggle now lives only on /insights, folded into the hero meta band where there is room for it. The dashboard ditches the always-visible knob.
• /insights: single page-level refresh button. The hero owns the only refresh affordance; redundant per-section refresh links removed (the per-recommendation Regenerate button from v1.4.16 stays).
• /insights: small BP / Weight tile strip removed. Duplicated the dashboard tiles. -157 lines on src/app/insights/page.tsx plus dead helpers, plus the orphan "Persönlicher AI Berater" subtitle.
• AI insight prompt no longer opens with a default-positivity sentence about data quality. GROUND RULE 7 (EN + DE) forbids "Your data foundation is strong" / "Datengrundlage ist sehr stark" openers; data-quality caveats only allowed when n < 7 in the analyzed window, recencyDays > 14, or a coverage gap biases the comparison. PROMPT_VERSION bumped 4.16.1 → 4.19.0 so feedback aggregation can attribute responses to the new rule.
• Settings input heights, vertical spacing, and right-side action buttons consistent across all sub-routes (mobile + desktop). Every form input is now 36 px (h-9); Account → Password, Account → Restart onboarding tour, and Dashboard → Reset to defaults stack the action below the title on <sm (full-width) and right-align on ≥sm, fixing the Pixel-5 right-edge overflow on the tour button. Language select gets its own row at the bottom of the Profile card; card-internal space-y standardised to space-y-4.
• Target-range status labels translated to German (Low / On Target / Stable / Moderate). 11 targets.label.<TYPE> + 41 targets.status.<key> entries in EN + DE; page uses STATUS_CATEGORY_KEY to normalise server strings.

Deferred to v1.4.20

• 3 HIGH from QA — /insights data?. narrowing refactor, /admin/api-tokens touch-tooltip (needs Popover swap), and /insights hero density (folded into the v1.4.20 redesign).
• 31 MED + 16 LOW from the quality-of-life audit. Short-list at .planning/v1420-backlog.md.
• /insights redesign with AI Coach — separate roadmap, design handoff at ~/Downloads/design_handoff_insights_redesign.

[1.4.18] — 2026-05-10

Added

• Per-chart overlay toggles. Every chart on the dashboard now has a cog menu (44 × 44 tap target) with three independent switches: trend indicator, trend arrow, and target-range overlay. Defaults are off so the default look is a clean line. State is persisted per user per chart in User.dashboardWidgetsJson.chartOverlayPrefs (no migration) and round-tripped through a new PUT /api/dashboard/chart-overlay-prefs in a Serializable transaction.
• Expanded achievements roster. 21 new achievements bring the total to 59. Adds streak, milestone, consistency, improvement, and discovery categories on top of the existing security / engagement / vitals / medication groups. Locked public badges only render once the user has data for the underlying metric so the page isn't a wall of grey on day one.
• Hidden Easter-egg achievements. Six hidden badges that paint as opaque "Hidden achievement" placeholders until unlocked. The real strings, descriptions, and icons never reach the DOM (or the API response) for locked-and-hidden entries, so peeking the bundle or the network tab doesn't spoil them. Unlock toast adds a longer Sparkles celebration with a "you unlocked a hidden achievement!" headline.
• BD-Zielbereich tile 7T / 30T sub-values. The two sub-values on the blood-pressure-in-target tile now show real measurement data. Backed by a new computeBpInTargetWindows() helper that re-uses the v1.4.16 ceiling predicate but filters input by measuredAt. /api/analytics surfaces bpInTargetPct7d / bpInTargetPct30d.

Changed

• Charts use clean lines without gradient fills. The v1.4.16 Apple-Health-style gradient backgrounds are gone. Lines stay smooth- interpolated, tooltips stay rich, animation-on-render still respects prefers-reduced-motion — only the gradient fill area is removed.
• Mood chart shows simple dots at data points. The emoji glyphs introduced in v1.4.16 are replaced with plain coloured dots; the emoji still appears in the tooltip.
• Personal-baseline / mean overlays are opt-in. The 90-day-median reference line on health and mood charts is no longer always-on; it only renders when the per-chart Trend toggle is enabled.

Fixed

• /admin/api-tokens mobile horizontal scrollbar. Third attempt, this time pinned to the actual offender via Playwright probe of the prod page at Pixel-5 viewport. The scrollbar was painted by the AdminShell mobile section strip (13 entries, scrollWidth ≈ 1700 px), not the api-tokens table. Added a .no-scrollbar utility and applied it to both AdminShell and SettingsShell mobile strips. Swipe and keyboard-arrow scrolling preserved.
• /insights legacy-payload crash. Already shipped in the v1.4.17 hotfix; documented here for completeness. Cached pre-strict insights in the v1.4.14 {changed, stable, drivers, …} shape now render a "Regenerate insights" card instead of throwing Cannot read properties of undefined (reading 'replace').
• BD-Zielbereich 7T / 30T sub-values. Were always rendering "—" because /api/analytics only computed a single 30-day window and the tile passed avg7={null}, avg30={null}. Wired correctly — see Added.

Deferred to v1.4.19 / v1.5

• i18n bundle leak (security HIGH). The hidden-achievement redaction landed at the API layer, but messages/en.json and messages/de.json are still statically imported into the client bundle, so a determined user can Cmd-F for the hidden strings in _next/static/chunks/*.js. Needs a build-time strip or reversible obfuscation. Tracked in .planning/v1419-backlog.md.
• See .planning/v1419-backlog.md for the short-list and .planning/v15-backlog.md for the strategic v1.5 items.

[1.4.17] — 2026-05-10

Fixed

• /insights no longer crashes for users with cached insights from before v1.4.16. A "Regenerate insights" card is shown for legacy cached payloads (the pre-strict {changed, stable, drivers, …} shape) instead of throwing a Cannot read properties of undefined (reading 'replace') error. One click on the card refreshes the insight in the new format.

[1.4.16] — 2026-05-09

Added

• Per-recommendation explainability. Every insight recommendation now carries a rationale: which time window was analysed, what was compared, and the deviation that triggered the recommendation. The card expands inline to reveal the rationale plus a mini-chart of the data window.
• Confidence score per recommendation. Each recommendation gets a deterministic 0–100 confidence score (server-computed from sample size, recency, and signal strength) shown as a colour-banded ring + bar meter. Below-threshold recommendations are tagged "low confidence — based on limited data" rather than hidden.
• "Was this helpful?" feedback. Thumbs-up / thumbs-down on every recommendation, persisted per user with provider attribution. Daily aggregator writes per-(severity × provider) helpful-rate to admin settings; the aggregate is visible under /admin/ai-quality.
• Medical-reference grounding. Recommendations cite curated AHA / ESH / ESC / WHO / DGE guidelines via a validated referenceId; the citation links open the source guideline in a new tab.
• Multi-provider AI fallback chain. The insight wrapper tries each configured provider in turn on hard failures (401 / 403 / 429 / 5xx / transport). Schema 422 still bubbles. Last-working provider is cached per user for an hour. Order, enable / disable, and provider list are configurable under Settings → AI.
• Apple-Health-style chart polish. Blood pressure, weight, pulse, body fat, sleep, steps, mood, and medication-compliance charts gain gradient fills, smooth interpolation, a 90-day-median personal-baseline reference line, in-target zone shading, rich tooltips with delta vs. baseline, and 600 ms ease-out animation that respects prefers-reduced-motion. Sparse data (<3 points) renders an explicit empty state instead of a degenerate line.
• Comparison overlay (vs. last month / vs. last year). A new toggle at the top of every chart, tile, and the insights surface overlays the prior period as a dimmed line beneath the current one and adds a delta callout (Δ ±N). The AI summary narrates the comparison ("your average BP improved by 4 mmHg vs. last month") when the toggle is active.
• Settings → Export. Consolidated /settings/export page with one card per export type: doctor-report PDF (configurable date range + practice name), measurements CSV, medications CSV (optional intake history), mood CSV, full JSON backup. Each download writes a user.export.<kind> audit-log entry and shares a 10/h rate-limit bucket. Doctor-report entry-point relocated under this route.
• Achievements page. New /achievements page with locked + unlocked breakdown grouped by category (medication / vitals / security / engagement). Recent unlocks card on the dashboard, toggleable from layout settings.
• Onboarding tour for new users. First-run spotlight walk-through highlighting tile-strip, quick-add menu, insights, integrations, and achievements. Skippable, keyboard-navigable, replayable from Settings → Account.
• Admin host-load chart. New chart over the system-status section shows host CPU, memory, and disk-IO over the last 2 hours, sampled every minute, retained for 7 days.
• Admin app-log preview. Tail of the last 1 hour of structured wide-events from the per-process ring buffer, filterable by trace_id / level / action / time-window with a JSON inspector modal.
• Admin AI quality preview. New /admin/ai-quality route surfaces helpful-rate per (severity × provider), tinted by band so degrading providers stand out at a glance.

Changed

• Insights surface uses the new RecommendationCard everywhere. The /insights page and the dashboard insights tile both render the polished card — rationale expand, confidence meter, citation footnote, feedback thumbs — backed by a shared TanStack Query cache.
• Trend label normalised to "7-day trend". Every chart, tile, and subtitle uses the long form. A signed numeric delta indicator (±N.N) with metric-aware colouring appears next to the value on every chart, including mood and medication-compliance.
• /admin overview redesigned. The section grid is gone; the overview now shows a system-status snapshot with host-load chart and an audit-log preview. Sidebar carries the section list.
• Sidebar admin sub-items only expand on /admin/*. Clicking the Admin link or opening the Gravatar dropdown no longer auto-expands the sub-list when you are not on an admin route.
• Settings → AI is a single dropdown. The provider selector at the top drives the configuration form below; no more top/bottom split. All five providers (Codex / OpenAI / Anthropic / Local / Admin OpenAI) are reachable from the same UI.
• Top dashboard tiles selectable per metric. The widget-id enum bug from v1.4.15 that silently 422'd every layout PUT is fixed; the per-metric tile toggle in layout settings now actually persists.
• AI rate-limit raised to 10/hour. Default bumped from 2/h to 10/h; configurable via INSIGHTS_RATE_LIMIT_PER_HOUR. Generating a new insight evicts every previously cached per-status insight for that user, so the dashboard never shows a stale cached payload.

Fixed

• BD-Zielbereich percentage now counts in-range readings correctly. The v1.4.15 fix corrected the denominator but kept the ESH narrow-band predicate (sysLow ≤ sys ≤ sysHigh AND diaLow ≤ dia ≤ diaHigh), so normotensive readings (e.g. 117/79) below sysLow=120 counted as out of range. Predicate switched to one-sided ceiling semantics with a hypotension floor (90 ≤ sys ≤ sysHigh AND 50 ≤ dia ≤ diaHigh), centralised in isBpReadingInTarget() shared by six call sites.
• Trend on "all" filter shows a meaningful split-half delta. Long windows where the per-week rate fell below the 1-decimal display precision now also surface a split-half mean delta (second-half mean minus first-half mean) for windows ≥ 90 days.
• Login overview no longer strips umlauts. The geo helper decodes via arrayBuffer() + TextDecoder('utf-8') instead of Response.json(), so an upstream proxy stripping the Content-Type: charset parameter cannot poison the umlaut path. Nürnberg, München, Düsseldorf, Köln, Würzburg, Bückeburg, Weißenfels all roundtrip correctly.
• /admin/api-tokens table no horizontal overflow on mobile. The desktop <table> falls back to a card list at <md viewports, with long names + permission badges wrapping cleanly inside the card.
• Skip-link no longer blocks logo click. The "Skip to content" shortcut still leads the tab order but no longer blocks pointer events on the logo.
• Bug-Report nav entry follows the admin feature toggle. When the admin disables bug reporting the entry vanishes from sidebar, bottom-nav, topbar, and the error-detail "Report bug" button.
• Feedback link follows the admin feature toggle. When feedback collection is disabled, the UI entry point disappears too.
• Cached AI insights replaced when the user regenerates. Generating a new insight invalidates the per-status audit_logs entries plus the TanStack Query cache, so the dashboard always shows the freshest payload.

Performance

• Comparison overlays computed via reusable bucket-series helper. No extra round-trip per chart — the dashboard fetcher and AI snapshot both read from the same avg30LastMonth / avg30LastYear fields.
• /api/insights/feedback persists with optimistic UI updates. Thumbs-up / thumbs-down apply instantly; the localStorage refresh- defence keeps the verdict on rerender even before the mutation resolves.

Security

• AI provider apiKeys encrypted at rest. Provider chain entries that carry a key store it AES-256-GCM via the existing src/lib/crypto.ts helper.
• /api/insights/feedback gated by requireAuth + idempotency-key. The dedicated rate-limit bucket prevents thumbs-spam.
• Per-provider attribution server-filled. Clients cannot tamper with which provider gets credit for a recommendation; the attribution is resolved server-side from the latest insights.generate audit row.
• Admin egress redacts secrets. Audit-log details and app-log meta fields run through redactSecrets() before leaving the admin API surface.

Internal

• docker-publish workflow no longer hangs on main-branch builds. Root cause was a qemu-arm64 SIGILL during multi-arch emulation; arm64 dropped from the platforms list. Native arm64 runner matrix scheduled for v1.5.
• CI integration tests + e2e workflows green again. Both had been pre-existing red since d8c549e (encryption-key YAML scalar parsed as integer 0 + spotlight tour overlay intercepting clicks). Both fixed this milestone.

Deferred to v1.5

• Coolify image-digest auto-deploy trigger (currently fires on every git-push; the manual Coolify UI toggle is the realistic fix).
• Native arm64 runner matrix for full multi-arch docker publish.
• Cross-user feedback aggregation prompt-tuning ratchet (depends on v1.4.16 feedback collection accumulating data).
• Dedicated /insights/compare page (i18n keys comparison.insightsCallout.{lastMonth,lastYear} reserved).

[1.4.15] — 2026-05-09

Added

• Backups become a full lifecycle. The Sunday-morning snapshot is no longer the end of the road. /admin/backups lets you download any snapshot as .json, upload a new one, and — behind a triple-confirm gate (type “RESTORE” + dialog + confirm) — restore a snapshot straight into the database. Every operation (run, download, upload, restore including start/failure) is recorded in the audit log with actor and target snapshot.
• New /achievements page lists locked + unlocked achievements with progress bars ({current} / {target}), grouped by category (medication, vitals, security, engagement). The dashboard gains a toggleable “Recent achievements” card; visibility lives in the Layout settings.
• New onboarding tour for first-run users. A spotlight walk-through on first dashboard load points out the tile strip, quick-add menu, insights, integrations, and achievements. Skippable with Esc, fully keyboard-navigable, honors prefers-reduced-motion. Replay the tour any time from Settings → Account.
• Doctor-report v2. Before the PDF is generated a dialog asks for the date range (presets 90 days / 6 months / 12 months, manually editable, max 2 years) and an optional practice name that appears on the PDF cover page. The practice name is persisted as a user preference.
• Auto-deploy on GHCR push. Once the Docker publish action ships a new :latest, it calls the Coolify deploy webhook. Coolify in turn pings an internal endpoint with the result; success / failure / unknown all land in the audit log; persistent failures send a Telegram alert to every admin. No more manual force-pull on the host.
• Empty states everywhere. Brand-new accounts and empty lists now always show a sensible empty state (icon + description + CTA) where there used to be just white space. Coverage: admin tables (users, backups, login-overview, api-tokens, feedback, audit-preview), measurement / mood / medication / achievement lists, the insights top-level + BMI-without-height view, and the dashboard for fully empty accounts.
• Notification channel status UI. Settings → Notifications now shows per-channel (Telegram, ntfy, Web Push) the current state (connected / error / disabled), last success, last failure, consecutive-failure counter, and disable reason if any. Buttons for “Re-enable” (only when auto-disabled) and “Send test”.
• Withings + moodLog integration status UI. Settings → Integrations shows per-provider the connection state, last sync, last error, and a reauth hint as soon as a refresh-token was rejected. After persistent failures (≥ 3 in a row) admins receive a Telegram alert if the channel is enabled.
• Top dashboard tiles selectable. The layout settings now expose a separate toggle for each metric’s upper-row tile and lower-row chart. Existing saved layouts keep their previous behaviour (one switch controls both surfaces) until you explicitly flip the new toggle.
• 7-day-trend instead of 7-day-average. Each tile gains a coloured delta indicator (±N.N) next to the value, showing the metric-aware change of the last 7 days vs. the prior 7. Label renamed from “7d average” to “7d trend”.

Changed

• The /admin overview replaces the section grid with an audit-log preview (recent entries, actor, target resource) and a system-status snapshot. The section grid moved into the sidebar.
• The sidebar Admin sub-items only expand when you are actually on an /admin/* route. Everywhere else the Admin group stays collapsed.
• The mood chart now auto-aggregates: weekly past 90 days, monthly past 730 days — same thresholds as weight and BP. A chip in the chart header shows the active aggregation level.
• AI insights gain hard anti-hallucination guardrails. Provider responses are validated against a strict Zod schema (summary, recommendations with mandatory metricSource, citations, warnings). Recommendations citing data points not present in the snapshot are rejected. The wrapper retries exactly once with a corrective system message; if the second attempt also fails, it returns 422 instead of unsanitised output. Codex-backend slug drift (e.g. gpt-5-codex → gpt-5.3-codex) is now cushioned by a configurable fallback chain + 1-hour positive cache; if every slug fails the route returns a structured 503 with the attempted[] list.
• The /admin/api-tokens table is responsive on mobile. Narrow viewports gate columns behind breakpoints (last-used, created-at, owner) and the owner username falls back inline next to the token name so hiding the column never drops data.
• Mood tile on mobile shows only the large score number + label, no more doubled rendering.
• Quick-add submenu disambiguated. The two entries are now called “Messung erfassen” / “Stimmung erfassen” (DE) and “Log measurement” / “Log mood” (EN) — previously both simply “Add”.

Fixed

• Blood-pressure target-range percentage. The target-range tile miscounted sys/dia pairs once import drift pushed sys/dia timestamps more than 5 minutes apart — the tile could show 0 % even though most readings were inside the target range. Fix: a same-Berlin-day key fallback + pair-count as denominator.
• Onboarding flicker. On accounts where onboarding is already complete, the onboarding card no longer renders for ~500 ms before vanishing. It mounts only after the analytics status has loaded, and refuses to auto-open when nothing is left to do.
• The “Skip to content” skip-link still leads the tab order but no longer blocks clicks on the logo.
• The “Report a bug” entry follows the admin feature flag. With bug reporting disabled, the entry vanishes from the sidebar, bottom-nav, topbar, and the error-detail “Report bug” button.
• The Feedback link follows its admin feature flag. With feedback disabled, the UI entry point disappears too.
• Notification channels auto-disable on persistent hard rejects. If Telegram / ntfy / Web Push respond repeatedly with 410 or other permanent reject codes, the channel disables itself and writes an audit-log entry. Status + re-enable button live in Settings → Notifications.
• reauthund der Settings-Eintrag bittet um Neu-Verbindung — statt jeden Sync-Tick weiter gegen den Provider zu hämmern. _Refresh-token failures flip the integration to “needs reauth”. When the Withings or moodLog refresh-token exchange fails (typically after 90 days without re-auth), the integration switches toerror_reauth` and the Settings entry asks for re-connect — instead of hammering the upstream every sync tick.
• Mobile chart containers no longer eat vertical scroll. On touch devices the Recharts wrappers swallowed vertical pans; on slower devices that felt like a scroll lockup. Fix: touch-action: pan-y on the chart wrappers, vertical scroll passes through again.
• /admin/users on mobile renders as a card list instead of a horizontally-scrolling table.
• Accessibility round of fixes: chart range buttons, medication primary buttons, mood-list mobile icon buttons, login CTAs, Settings → Account passkey table, onboarding-tour focus trap + DE-locale overflow + backdrop ring — all aligned to 44 px tap targets and labelled / keyboard-navigable.

Security

• AI provider responses are validated against a strict Zod schema. The insight wrapper only accepts responses that satisfy the strict aiInsightResponseSchema, and rejects recommendations citing data points absent from the supplied snapshot. Schema failures trigger a single retry with a corrective system message; a second failure returns 422 instead of hallucinated output.
• Backup operations are fully audited. Run, download, upload, and restore — including start markers, denial reasons, and failures — each write an audit-log entry with actor and snapshot ID. Restore is additionally protected by five independent gates (cookie-only admin auth, confirm: "RESTORE" body, typed UI confirmation, idempotency-key wrap, pre-transaction enum validation).

[1.4.14] — 2026-05-09

Added

• The admin area is split into per-section pages instead of one monolithic dashboard with anchor jumps. Each section has its own URL (/admin/system-status, /admin/services, /admin/integrations, /admin/feedback, /admin/reminders, /admin/users, /admin/api-tokens, /admin/login-overview, /admin/backups, /admin/danger-zone); the sidebar grows an expandable Admin group; status cards link to the relevant sub-page; legacy /admin#section-… paths are redirected server-side.
• New /admin/backups view with a table of all stored backups (size, type, timestamp) and a “Backup now” button that enqueues an ad-hoc pg-boss job.
• New /admin/users view with role filter pills (all / admins only / users only) and a per-row force-logout action behind a confirmation dialog (deletes every active session of the target and writes an audit-log entry). Self-target is disabled.
• New “Remove saved AI key” button in Settings → AI: a clearly labelled button behind a confirmation dialog clears the stored OpenAI or local provider key without touching anything else.
• MODEL-Env-Var** als Operator-Override für das Codex- Modell-Slug, damit alternative Modelle ohne Rebuild getestet werden können (z. B. wenn dein ChatGPT-Plan ein anderes Default-Modell bevorzugt). _New CODEX_MODEL` env var lets operators override the Codex model slug without a rebuild — useful for testing alternate slugs against different ChatGPT plan tiers.

Changed

• Trend-arrow colors are metric-aware: BP and weight rising = orange (warning), mood rising = green (positive), pulse rising = neutral (context-dependent). Arrow direction itself is unchanged.
• “Wipe all data” now also clears notification channels and web-push subscriptions: encrypted Telegram bot tokens and web-push endpoints no longer survive a full account wipe. Feedback and audit log stay untouched (unchanged). The confirmation copy spells out the new scope.
• Admin-area i18n keys reorganised under admin.section.<slug>.* (EN + DE parity).

Fixed

• Codex/ChatGPT model slug corrected: the Codex backend rejects both gpt-5-codex and gpt-5 when authenticated via a ChatGPT account; the codex-optimised slug for the Plus/Pro tiers is gpt-5.3-codex. v1.4.14 wires the correct default. Settings → AI “Test connection” and the insight generator now both succeed against your ChatGPT subscription.
• Sommerzeit-Wechsel verschiebt keine Tageswerte mehr. Die Cross-Metric-Tagespaarung in den Insight-Buckets rechnete früher in reinem UTC und verlor an den Berliner DST-Grenzen einen Tag. Die neue Helper dayOffsetToBerlinDayKey() arbeitet DST-immun (Anker über Berliner Y-M-D, dann Subtraktion in 86400_000-ms-Schritten); die Tagespaarung über Blutdruck, Gewicht und Stimmung ist jetzt über DST-Wechsel hinweg konsistent. _DST transitions no longer shift daily values. The cross-metric daily bucket pairing previously did naive UTC math and dropped a day at the Berlin DST boundary. A new dayOffsetToBerlinDayKey() helper anchors at Berlin Y-M-D and subtracts in 86_400_000-ms steps; bucket pairing across blood pressure, weight, and mood is now DST-safe.
• AI provider errors are now correctly classified by /api/insights/generate: provider 401/403 → 422 (“AI provider rejected the request — check your API key in Settings → AI”), provider 5xx → 503 (“AI provider temporarily unavailable”), 429 → 429. Previously everything returned 500. Full error context still lands in the structured logs.
• The structured-logging secret redactor no longer mangles innocent words. The previous regex matched any sk-… substring and masked fragments inside task-force, risk-management, disk-io. The new pattern requires a word boundary and at least 8 trailing characters, while still scrubbing real API keys (sk-…, sk-ant-…).

Performance

• Bundle-size improvements on the insights page: Recharts symbols for the correlation scatter plots are now loaded on demand via next/dynamic instead of being shipped eagerly, saving roughly 108 KiB of initial JavaScript on /insights. Chart visuals are unchanged.
• The dashboard skips the onboarding-checklist API requests once onboarding is complete. With onboardingCompletedAt set, the withings/status and notifications/preferences queries no longer fire on dashboard load — saves about 950 ms of network time for established users.

Tests & A11y

• Extended end-to-end suite. New Playwright specs cover the authenticated dashboard render, the “add measurement” flow, the doctor-report PDF download, a mocked Codex connect flow, a mocked insights-generate flow, and a mobile-viewport smoke test (Pixel 5).
• Axe-core accessibility audit now clean of serious/critical violations on /dashboard, /settings/integrations, and /admin (incl. /admin/system-status, /admin/users). Fixes: missing aria-labels on icon-only buttons, unnamed mobile user-menu trigger, empty <dd> placeholders, sign-up link distinguishable only by color, quick-add menu with two indistinguishable items.

Docs

• Documentation site brought up to date with v1.4.14 — Codex device-code flow rewritten, new Admin sections (Backups, Users) documented, CODEX_MODEL env var added, dashboard performance note added, Codex troubleshooting block revised.

[1.4.13] — 2026-05-09

Fixed — KI Insights via ChatGPT

• Modell-Slug für ChatGPT-Auth korrigiert. Der Codex-Backend lehnt gpt-5-codex mit ChatGPT-Subscription ab (The 'gpt-5-codex' model is not supported when using Codex with a ChatGPT account.) — dieses Slug ist nur für API-Key-Auth gültig. Wechsel auf gpt-5, das Standard-Modell der ChatGPT-Plus/Pro-Tarife. Operator-Override via CODEX_MODEL-Env-Var möglich falls dein Plan einen anderen Default kennt.

[1.4.12] — 2026-05-09

Fixed — KI Insights via ChatGPT (komplette Codex-Integration)

• Codex-Backend-Aufruf jetzt vollständig nach Spec. Die letzten Versionen haben den Connect-Schritt richtig hinbekommen, aber der eigentliche Insight-Call ist iterativ an immer neuen 400ern gestorben. Statt weitere Trial-and-Error-Iterationen zu fahren habe ich das vollständige Codex-Backend-Protokoll aus dem offiziellen openai/codex-Quellcode dokumentiert (docs/codex-protocol-spec.md) und einmal sauber dagegen implementiert. Was alles fehlte: der Header ChatGPT-Account-ID (ohne den 401, kommt aus dem chatgpt_account_id-Claim im JWT id_token); die Header originator, User-Agent, Accept, session_id, thread_id; die Body-Felder reasoning: null und include: []; das richtige Modell-Slug gpt-5-codex (statt des Test-Placeholders gpt-5.3-codex); JSON-Body beim Refresh (vorher form-urlencoded); Persistenz des accountId neben dem Access-Token. SSE-Streaming wird unverändert konsumiert (output_text.delta + output_item.done).
• Aufräumen: der Browser-Authorization-Code-Pfad (/api/auth/codex/authorize + /callback) ist gelöscht — er funktioniert auf hosted Domains grundsätzlich nicht (Hydra- Whitelist nur für localhost), war aber als Safety-Net noch da. Device-Code ist jetzt der einzige Pfad.
• Re-Connect nötig: wer in v1.4.7-v1.4.11 schon connected hat, muss einmal "Trennen" + "Mit ChatGPT verbinden" — die alte Storage-Form trug die accountId nicht und kann nicht nach-bereichert werden.

[1.4.11] — 2026-05-09

Fixed — KI Insights via ChatGPT

• Codex-Backend bekommt jetzt SSE-Streaming. Nach dem v1.4.10- Body-Format-Fix kam der nächste 400er: Stream must be set to true — der chatgpt.com/backend-api/codex/responses-Endpoint akzeptiert ausschließlich Server-Sent-Events-Antworten, kein synchrones JSON. v1.4.11 baut den CodexClient so um, dass er die Antwort als SSE konsumiert: output_item.done-Events liefern den vollständigen Assistant-Text, output_text.delta-Chunks dienen als Fallback, response.completed trägt die Token-Usage. Damit läuft das gesamte KI-Insights-Feature jetzt durch dein ChatGPT-Abo.

[1.4.10] — 2026-05-09

Fixed — KI Insights via ChatGPT

• Codex-Backend bekommt jetzt das richtige Request-Format. Nach dem v1.4.9-Connect war der OAuth durch, aber jeder echte Insight- Call ist mit Codex request failed (400) — "Input must be a list" gestorben. Der chatgpt.com/backend-api/codex/responses-Endpoint spricht das OpenAI-Responses-API-Schema (input: ResponseItem[]) und nicht das Chat-Completions-Schema mit String-Input. v1.4.10 baut den Body korrekt — input ist eine Liste mit einem Message-Item, das wiederum eine Liste von input_text-Content- Blöcken trägt — exakt wie die ResponsesApiRequest-Struktur im offiziellen codex-rs/codex-api/src/common.rs. Settings → KI "Verbindung testen" und der Insight-Generator laufen damit jetzt beide gegen dein ChatGPT-Abo durch.

[1.4.9] — 2026-05-09

Fixed — Settings · KI

• Device-Code-Flow läuft jetzt komplett durch. v1.4.8 hat den Code richtig zugestellt und du konntest auf chatgpt.com bestätigen, aber der Connect-Schritt am Ende ist mit "missing organization_id" gestorben. Ursache: der id_token aus dem Device-Flow trägt das organization_id-Claim nicht (das bekommt nur die Browser-Authorize-Variante via id_token_add_organizations=true-Param), und unsere RFC-8693-API-Key-Exchange hat genau dieses Claim erwartet. v1.4.9 übernimmt das Verhalten des offiziellen Codex CLI im Device-Pfad: den OAuth-Access-Token direkt verwenden und gegen den Codex- Backend-Endpoint (chatgpt.com/backend-api/codex/responses) schicken — kein API-Key-Tausch nötig. Refresh läuft analog: nur Token-Rotation, keine Exchange.

[1.4.8] — 2026-05-09

Fixed — Settings · KI

• "Mit ChatGPT verbinden" funktioniert jetzt wirklich. v1.4.7 hat zwar die OAuth-Endpoints korrigiert, ist aber an OpenAIs Hydra- Allow-List gescheitert: die Public-Codex-Client-ID hat in der Server-Allow-List nur localhost:1455/1457 als Redirect-URI, jeder hosted-Domain-Callback wird mit "An error occurred during authentication (unknown_error)" abgelehnt. v1.4.8 schaltet auf den Device-Code-Flow um — den selben Mechanismus den der offizielle Codex CLI für Headless-/Hosted-Umgebungen nutzt: HealthLog zeigt einen kurzen Code (RGRP-N5F7U-Stil), du gehst auf https://auth.openai.com/codex/device, gibst den Code ein, bestätigst bei dir im Browser, fertig. Kein Redirect zurück nötig, also keine Allow-List-Konflikte. Die Settings-Seite pollt im Hintergrund und schließt das Modal sobald deine Approval durch ist.

[1.4.7] — 2026-05-09

Fixed — Settings · KI

• "Mit ChatGPT verbinden" funktioniert wieder. Seit der Funktion Anfang v1.4.x existiert war der OAuth-Pfad gegen die falsche Domain verdrahtet — ChatGPT hat unsere Authorize-/Token-Requests still geschluckt und das normale Web-Interface gerendert, kein Callback, kein Fehler. Der Flow läuft jetzt über auth.openai.com/oauth/..., identisch zum offiziellen openai/codex CLI: PKCE-Authorize, Token- Exchange, dann ein zweiter RFC-8693-Token-Exchange, der den id_token gegen einen OpenAI-API-Key tauscht. Dieser Key bucht gegen das ChatGPT-Abo, kein separates API-Plan-Quota nötig. Der Refresh-Token wird verschlüsselt mitgespeichert; vor jeder Anfrage rotiert HealthLog den API-Key transparent wenn er abläuft.

[1.4.6] — 2026-05-09

Fixed — Dashboard

• Tile strip fills its row. Each tile in the dashboard's measurement strip now stretches to its grid cell instead of shrinking to content width. On a 375 px viewport tiles in the same row are no longer 122-166 px wide — every tile takes the same share of the row.
• Secondary text is finally distinguishable from primary. --muted-foreground was identical to --foreground in both light and dark mode, which flattened the entire visual hierarchy. Tile labels, "Ø7d:" prefixes, units, and inactive nav items now render in #9aa3b3 (dark) / #5b6273 (light) — both ≥ 4.5:1 against the surface.
• Trend cards land aligned with the chart strip below. Padding bumped from p-3 to p-4 md:p-6 so the tiles match the surrounding chart cards. KPI typography (text-3xl tracking-tight tabular-nums for the value, text-xs uppercase tracking-wide for the label) gives the number proper weight without making the tile feel tall.
• Always-on Ø7d / Ø30d chips — when an average is missing the chip renders — instead of disappearing, so vertical rhythm stays consistent across tiles.
• Welcome subtitle is visible on mobile (was hidden below the sm breakpoint) and uses muted-foreground so it doesn't fight the headline.
• Medications card matches the other cards — rounded-xl and p-4 md:p-6 instead of the smaller rounded-lg p-4.

New — Charts

• Long-range charts now bucket their data. Hitting "All" on an account with several years of measurements used to render thousands of daily dots — unreadable, and slow on mobile. The chart now picks an aggregation level from the visible range: daily for ≤ 90 days, weekly mean for 91-730 days, monthly mean for everything beyond. A small chip beside the chart title surfaces the active bucket ("Wochendurchschnitt" / "Monatsdurchschnitt" in DE, "Weekly avg" / "Monthly avg" in EN) so the bucket is never silent. Empty buckets are dropped rather than zero-padded.

Fixed — KI

• Hero recommendation no longer prints raw metric:WEIGHT tokens. When the model embedded a chart token in the primary recommendation the renderer was printing the literal string. The "Key Takeaway" card now strips the tokens for prose and renders them as inline charts under the recommendation, the same pattern the summary block has used since v1.4.5.
• "Verbindung testen" stays readable when the model returns bad JSON. /api/insights/generate returned 502 for parse errors, which Cloudflare swapped for an HTML error page; await res.json() in the browser then crashed. Same Cloudflare-rewrite trap the v1.4.5 ai/test fix solved — parse errors now map to 422 so the JSON body actually reaches the client.
• Saved API keys cannot leak to a stale local URL. A user who had configured the Local provider with http://192.168.x.x and later switched to OpenAI / Anthropic kept that URL in the shared aiBaseUrl column, and the OpenAI / Anthropic clients were forwarding their cloud keys to that LAN host on every request. The PATCH that switches providers now wipes the column, and the OpenAI / Anthropic clients hardcode the canonical base URL regardless of what the column carries.

Improved — KI Insights

• The model now sees three years of history per metric. Each per-card insight payload (general, blood pressure, pulse, weight, BMI, mood, medication compliance) used to clip the series to the last 30 daily means — way too narrow to detect drift that plays out over a year. The new payload combines 360 daily means (dayOffset 0..359) with 24 monthly means for the older window (monthOffset 12..35), with a 50 KB safety guard that re-buckets at 180 daily days when a particularly noisy account would blow past the prompt token budget.

Fixed — Admin

• Status-card CTAs go to the right place. Every "Manage users" / "View backups" link in the admin status grid was bouncing back to /admin because the hrefs were pointing at sub-routes that never shipped (/admin/users, /admin/audit-log) or at anchors whose IDs do not exist (#integrations, #monitoring, #backups). Each href now points at a real section-* anchor on the admin page, the CTA copy describes the destination honestly ("Open integrations", "Open system status"), and the unit test asserts each href maps to a known section ID — so the next refactor cannot regress this silently.
• Bug-report toggle finally hides the form. The admin "Bug reports" switch had no effect because the gate lived on a legacy route the form does not call. The actual /api/feedback endpoint and the /bugreport page now both honor the toggle — the form disappears, and direct API calls return 503 with a readable error.
• Audit trail survives the data wipe. The Wipe all data admin action used to delete AuditLog in the same transaction as the rest of the user data, which silently destroyed the one record actually saying "an admin wiped data". The wipe now leaves the audit log alone and adds an explicit admin.data.clear.start entry before the transaction begins, so even a crash mid-wipe leaves a trail. The success copy also enumerates the full scope (API tokens, Withings connections, auth challenges) instead of pretending only measurements / medications / intakes are affected.
• Cached insight reloads no longer burn a rate-limit token. POST /api/insights/generate checked the rate limit before the cache return, so a noisy dashboard refresh would lock you out for an hour even when every request returned the same cached envelope. The check moved below the cache return.
• One failing health probe no longer blanks the whole admin status grid. Promise.all in the status-overview API short-circuited on the first rejection. Promise.allSettled forces failed probes to the alert severity and lets the rest render normally, with a Wide Event annotation noting which probe(s) failed.
• Settings load errors surface inline instead of spinning forever. When useSystemStatus or useAdminSettings rejects, the admin page now shows a "Failed to load…" banner instead of an indefinite skeleton.

Improved — Settings · KI

• The KI section is fully internationalised — about 30 hard-coded German strings now flow through t("settings.ai.…") keys, and the model-preset list drops gpt-5 (not a released model) and o3-mini (would require an o-series parameter contract that isn't wired up yet). The privacy "Raw data" warning uses Dracula tokens so the colour matches the rest of the panel.

Improved — Polish

• Numeric spans on the dashboard tiles use tabular-nums so digits stop jiggling on every refresh.
• The bottom-nav buffer is tighter on mobile and removed on desktop (pb-[calc(4rem+env(safe-area-inset-bottom,0px))] md:pb-0), so desktop content sits flush instead of leaving an unused 5 rem strip.
• Onboarding "X von Y" / "%" progress drops the monospace font and keeps tabular-nums.
• Feedback inbox category badges use Dracula tokens (bg-dracula-red/15 text-dracula-red) for theme cohesion.
• Codex provider mirrors the OpenAI client's structured-error format (httpStatus / model / bodyExcerpt) so failures from ChatGPT-OAuth show the same readable message as failures from the BYO-key paths.
• Logging redacts third-party AI keys: redactSecrets now scrubs sk- / sk-ant- patterns so a misconfigured client cannot leak its key into Wide Events. The idempotency body-content guard refuses to cache responses that contain those prefixes (with a regex tight enough to avoid false positives on words like "task-id" or "risk-management").
• Danger-zone result colour follows mutation state instead of string-prefix-matching localized copy.

Repo housekeeping

• e2e workflow is back to green: dropped the pnpm/action-setup version override (now reads packageManager from package.json), switched the mobile Playwright project from iPhone 13 (webkit) to Pixel 5 so chromium-only CI installs are enough, anchored the locale-cookie test at the configured base URL, and made the login spec open the password form before asserting on its inputs.
• Repo-wide prettier sweep — long-deferred reformatting drift closed before the v1.4.6 tag.

[1.4.5] — 2026-05-09

Fixed — Settings · KI

• "Verbindung testen" no longer crashes the page when the key is bad. The endpoint mapped every upstream error to HTTP 502, which Cloudflare intercepts and replaces with its own HTML error page. await res.json() in the browser then crashed with Unexpected token '<', "<!DOCTYPE ". 401/403 from the provider now map to 422, 429 to 429, and only genuine 5xx upstream errors keep the 502 — Cloudflare passes 4xx through untouched, so the React Query mutation reads the JSON body and surfaces a readable message.

Fixed — Dashboard

• Dashboard tiles use a CSS Grid layout again — the v1.3-era pattern that gave each tile an identical width with symmetric gaps and an edge-to-edge fit with the charts below. v1.4.4 distributed width via flex-1 basis-0; CSS Grid is more honest about the intent and survives viewport changes more gracefully. grid-template-columns: repeat(auto-fit, minmax(9rem, 1fr)) keeps every track equal-width with a 9 rem floor; the row wraps when the floor no longer fits instead of triggering a horizontal scroll.

[1.4.4] — 2026-05-08

Fixed — Dashboard

• Blood pressure is now two distinct tiles again (sys + dia next to each other) — the v1.4.3 attempt at a combined tile read as a single double-wide entry; reverting to two separate tiles preserves visual rhythm with the other metrics.
• All tiles share an equal width. The previous strip used shrink-0 grow basis-[10rem], which gave each tile a 160 px floor and let wider content (like the BP tile) push past it. Switched to flex-1 basis-0 min-w-[9rem] — every tile now starts from zero and gets the same share of the available row width, with a 9 rem floor so they stay readable on narrow viewports. The strip scrolls horizontally if the row no longer fits.

[1.4.3] — 2026-05-08

Fixed — Dashboard

• Tile strip is now the same width as the charts below it. The small negative-margin bleed that helped the snap-scroll feel on mobile was leaking onto desktop and made the tile row 16 px wider than the chart strip. Fixed at md and up.
• Tiles all have the same height. Blood pressure used to render as two stacked tiles inside one slot which made it taller than every neighbour. Sys/dia now share one tile and display as 117/79 mmHg with one trend arrow. Tile count drops from 6 to 5.
• Settings sub-section "Übersicht" renamed to "Dashboard" — matches the label in the main nav.
• "Persönliche Zielwerte" is its own settings section now at /settings/thresholds, instead of being buried inside the Dashboard settings panel under the layout customizer.

Fixed — Settings

• API & Tokens tables fit the content column on desktop.
• About → "Auf Updates prüfen" works again. Production CSP blocked the direct call to api.github.com — the check now goes through a server-side proxy. The page also auto-checks once on mount when the previous result is older than 24 h, and shows a "Zuletzt geprüft am …" timestamp so you can tell when the answer was confirmed.
• About restructured into three titled cards — HealthLog (version
  • license inline, no boxed badge), Quellen & Dokumentation, and Updates.
• KI provider — OpenAI users can enter their own API key. Schema didn't have a column for it before; added it, plumbed it through the resolver and test endpoint, surfaced the input in the Settings → KI panel.
• Model field is now a dropdown with provider-specific presets plus an "Eigenes…" option for power users.
• "Mit ChatGPT verbinden" no longer dead-ends on chatgpt.com. The OAuth URL was missing its client_id; with CODEX_OAUTH_CLIENT_ID set the handshake completes. When the env var isn't configured the button is hidden and a hint points the user at the API-key path.

Improved — KI Insights

• AI can illustrate findings with metric:MOOD charts inline. A mood drift or adherence-risk finding now renders the dedicated Mood chart under the paragraph instead of just prose.
• Every finding must cite a concrete number ("138/85 mmHg", "+0.4 mmol/L vs 30d-avg") rather than adjectives. Findings without a snapshot anchor are now omitted; cardinality is variable 0–8 sorted by salience. Generic boilerplate ("drink enough water", "consult your doctor", etc.) is explicitly forbidden outside the disclaimer.

Improved — Admin

• Bug-report feature has an explicit on/off toggle. Previously the only way to hide the report button was to clear the encrypted GitHub token, which forced a re-entry on resume.

Improved — Polish

• "Trennen" looks the same everywhere (Withings, moodLog, KI/Codex). Outlined button with red text — same affordance for the same action.

[1.4.2] — 2026-05-08

Fixed — Production deploy hotfixes

• Dashboard and Insights pages no longer crash for users without weight data. data?.summaries.WEIGHT only protected the outer object — the optional chain stopped one level too early, so brand-new users (where summaries is undefined) hit TypeError: undefined is not an object (evaluating 'E?.summaries.WEIGHT') on first load. Now data?.summaries?.WEIGHT.
• Container healthcheck uses 127.0.0.1 instead of localhost. busybox-wget in Alpine resolves localhost to IPv6 ::1 first, but Next.js standalone listens on IPv4 0.0.0.0:3000 only — so the healthcheck always returned ECONNREFUSED, Docker marked the container unhealthy, and Traefik returned 503 from the public URL even though the app was actually running. The Dockerfile-level HEALTHCHECK already used 127.0.0.1; the docker-compose.yml override was the one that drifted to localhost. Fixed.

Notes

• The 1.4.1 GHCR image never published cleanly (the docker-publish workflow reported success in GH Actions but the ghcr.io/mbombeck/healthlog:1.4.1 tag returned manifest unknown when Coolify tried to pull). The 1.4.2 release supersedes 1.4.1 and includes everything 1.4.1 was supposed to ship — the v1.4.1 source on main was always healthy; only the Coolify deploy surface was broken.

[1.4.1] — 2026-05-08

Security

• moodLog integration no longer accepts internal-network URLs. A user could previously save http://169.254.169.254/ (cloud-metadata) or any RFC1918 address as their moodLog instance; the daily sync worker would then fetch from that target with the user's API key in the Authorization header. The credentials write path now refuses non-public hosts, the sync worker re-checks the URL at the actual fetch site (so legacy rows stored before the guard are also refused), and the fetch is now redirect: "manual" so a public host cannot 302 to an internal target with the bearer on the redirect hop.
• Error reports never echo bearer tokens, Telegram bot tokens, or query-string secrets. WideEventBuilder.setError() and the Glitchtip incident path now run every error message and stack trace through a central redactSecrets() filter that scrubs Bearer …, Telegram bot<digits>:<token> URLs, and ?secret=, ?code=, ?token=, ?api_key= query strings. The substitution is generic [REDACTED] so partial entropy is never revealed.

Fixed — Citation accuracy

• Blood-pressure classification now cites ESH 2023. The dashboard tile, the doctor-report PDF, and the inline analytics comments used to label the band as "ESC/ESH 2018". The numbers haven't changed (the 2023 ESH update kept the 2018 thresholds), but the joint authoring did — ESC withdrew from the 2023 document, so the correct citation is "ESH 2023" alone.
• Steps target source label is Saint-Maurice JAMA 2020 instead of WHO. Every other surface in the app (AI prompts, inline comments, drift tests) already enforced this attribution; the insights/targets surface was the last "WHO" label in the tree. WHO publishes physical-activity time, not a step quota.
• Saint-Maurice "mortality plateau 8000–12000" attribution softened. The original JAMA 2020 paper reports continued dose-response benefit (HR 0.49 at 8k, HR 0.35 at 12k) — not a plateau. The plateau-shaped finding belongs to Paluch 2022 Lancet Public Health (PMID 35247352), not Saint-Maurice. The inline comments and AI prompts now say "continued dose-response benefit through ~12,000 steps/day" instead.

Added — CI safety nets

• Postgres-backed integration test suite is now executable. The testcontainers infrastructure shipped in 1.4.0; this release wires the per-test boilerplate through vitest's globalSetup so all four files share one container. pnpm test:integration runs ten tests (rate-limit race, idempotency replay-attack contract, GDPR Article-17 cascade delete, session create / read / expire) against a real Postgres in under four seconds. CI runs the suite on every PR.
• Playwright + axe-core E2E foundation. A new pnpm e2e runs five public-surface specs (version endpoint, proxy auth-redirect, login form autofill hints, DE/EN locale switch, axe-core accessibility gate) against the production build in CI. Authenticated flow specs (quick-entry, doctor-report, settings round-trip, test-buttons, onboarding) ride a follow-up release because they need a seeded test user; the foundation makes adding them a one-PR step.

Changed — Admin internals

• Admin page is now per-section components. The status-card grid shipped in 1.4.0 sat on top of a 2,700-line monolith; that monolith is now 14 focused files in src/components/admin/ with a 77-line src/app/admin/page.tsx shell that mounts them. Every section keeps the same DOM, ids, query keys, and i18n keys — no user-visible change.

Fixed

• Final ESLint error is gone. The medications page's "API endpoint" dialog ran its initial-load fetch through a useCallback paired with useEffect and triggered the strict react-hooks/set-state-in-effect rule. Refactored to TanStack Query — same network calls, no effect, lint count is now zero on main.

Documentation

• Repo-internal docs synced for v1.4. README adds the Multi-tenant ready and Test connection buttons feature blocks, the API reference table includes the eleven new v1.4 endpoints, and the model count is corrected to 26 (RefreshToken). AGENTS.md and CLAUDE.md reflect the per-route /settings/[section] layout and the per-section admin layout. docs/api/openapi.yaml documents the new endpoints (version, refresh, refresh/revoke, status-overview, backup/test, the five test-connection probes). docs/migration/v1.3-to-v1.4.md corrects the now-wrong "no migrations" claim and adds full env-var sections for the worker/web split, encryption-key versioning, and off-host backup target.

Notes

• No database migration in 1.4.1.
• No environment-variable change required to upgrade.
• No API contract change — every route added in 1.4.0 is still there; no shapes or status codes flipped.
• The audit pass that drove this release identified five medium security items and three P0 performance items that warrant deeper architectural work; those are tracked in docs/ops/v141-followup-issues.md and ride a future release.

[1.4.0] — 2026-05-08

Added — Foundation, safer ranges, and a faster dashboard

• UI guidelines, design tokens, and shared primitives. A new docs/ui-guidelines.md is the single source of truth for spacing, typography, button hierarchy, dialog-vs-sheet decisions, accessibility baseline (WCAG 2.1 AA), and the autofill / honeypot pattern for health-data forms. Two new shadcn primitives — <Skeleton> and <EmptyState> — replace the previous mix of spinners and "No data" placeholder strings. Future v1.4.x components reference the doc; the primitives ship with screen-reader-aware semantics and respect prefers-reduced-motion.
• /api/version public endpoint exposing the build's version, optional Git SHA / build timestamp, license, and canonical links. Wires the future Settings → About surface and a thin "Check for updates" UX. Static-cached so the route adds zero DB load.
• src/lib/medical-citations.ts — single source of truth for cited medical guidelines (id, name, year, URL, caveat). Future medical surfaces import these constants instead of duplicating strings in code, prompts, and messages/*.json. A new drift-test asserts every entry has a non-empty URL + caveat and that the recurring "WHO ≥ N steps" hallucination cannot reappear as a constant.

Fixed — Patient safety and citation accuracy

• Diastolic blood-pressure orange band no longer reaches 60 mmHg. With the default age-based targets (DBP 70–79), the lower orange wing was computed as diaLow − 10 = 60. A reading of 60 mmHg landed in "mildly low" yellow instead of red even though that level is the general-adult hypotension threshold and the J-curve risk floor in ESH 2023 for treated hypertensives. Orange floor is now clamped at 65 mmHg, so 60 mmHg lands in red. The user-override path stays intact and remains audit-logged.
• BP guideline citations consolidated on ESH 2023. The codebase had a mix of "ESC/ESH 2018" (analytics) and "ESC/ESH 2023" (AI prompts). The 2023 hypertension document is ESH-only — ESC withdrew from the joint authoring — so neither label was correct. Every site now cites "ESH 2023" with the published source URL. Numbers unchanged.
• "WHO ≥ 8 000 steps/day" hallucination fully removed. WHO publishes activity time (150–300 min/wk moderate), not a step quota. The v1.3.3 fix only landed in effective-range.ts; four AI prompt strings and the getStepsRange() helper carried the old wording forward. Saint-Maurice et al., JAMA 2020 (mortality plateau 8 000–12 000) is now cited everywhere and the two surfaces agree on the band. Sleep target moves from "ESC" (no adult sleep guideline) to AASM 2015.
• Body-fat ACE bands corrected and three-way drift resolved. The classifier used essential = 6 (M) / 14 (F) as the floor — but that's actually ACE's Athletes lower bound. Readings below were mislabelled "Essential" instead of "Below essential" (a danger band). Six-band classifier now mirrors the ACE table, and the three sites that had three different green-band numbers (value-bands.ts, targets/route.ts, classifications.ts) all derive from getBodyFatTargetRange (ACE fitness + acceptable bands).
• Bedtime-glucose citation softened. ADA Standards 2024 §6 publishes pre-prandial 80–130 and post-prandial <180 — no published adult bedtime target. The 90–150 mg/dL band stays (reasonable adult overnight band) but the inline citation now states the absence explicitly and references ISPAD 2022 (pediatric) as the closest comparator.

Fixed — Localisation reaches the notification path

• Medication reminders now follow the user's locale. Telegram, ntfy, and Web Push reminders previously read "Erinnerung", "Bald fällig", etc. regardless of the user's stored language. Templates for every phase (green/yellow/orange/red) and every keyboard button now resolve from messages/{de,en}.json per med.user.locale. Telegram callback IDs stay stable English identifiers so the dispatcher keeps matching across locale changes.
• Dashboard greeting and streak label are localised server-side. Previously hard-coded "Hi, ${name}" and "Tage in Folge" — both now i18n-key-resolved.
• Mixed-locale Zod validation messages unified to English. Two measurement-form messages and four admin-validation messages flipped between German and English depending on which schema fired. All consolidated on English (the app is English-first; the German UI maps field labels client-side).

Fixed — Chart math edge cases

• summarize and trendSlope use the same time anchor. Averages snapped to Date.now(); slopes snapped to the latest point in the series. A stale series reported a trend even though the dashboard tile correctly hid the average. Both now anchor on Date.now(), so a stale series returns null consistently from every windowed stat.
• summarize([]) returns null for min/max/mean instead of zeros that leaked into chart axes and AI feature bundles as fake readings.
• weeklyAverages is Berlin-timezone aware. A Sunday-evening Berlin reading bucketed into the next week on the UTC production container because Date.getDay() was system-local. ISO-Monday key now resolves via Intl.DateTimeFormat({ timeZone: "Europe/Berlin" }).
• pairByTimestamp JSDoc documents the greedy nearest-match heuristic and when a Hungarian-style match would matter (sparse health data is well below that bar).

Fixed — Hidden friction

• AI provider connection-test honours the unsaved selection. Changing the AI provider in /settings, then clicking "Verbindung testen" without saving first, used to silently run the test against the stored provider — surfacing as a confusing OK / failure unrelated to what the user had on screen. Plaintext keys never persist; the existing SSRF guard, rate limit, and V3 error-leak shielding stay in place.
• Health-data inputs no longer autofill the user's account password. The base <Input> primitive defaults to autoComplete="off" plus the LastPass / 1Password ignore attributes whenever the caller doesn't pass a semantic value. Auth and profile forms continue to autofill normally because they pass an explicit autoComplete ("username", "email", "current-password", "new-password").
• Step-range target aligned across two callsites. getStepsRange() returned {7000, 10000} while effective-range.ts returned {8000, 15000}; two surfaces showed different "green" bands to the same user. Both now use {8000, 15000}, anchored on Saint-Maurice 2020.

Performance

• Two more N+1 queries closed. extractFeatures (used by every AI-insight route) issued one prisma.medicationIntakeEvent.findMany per active medication; replaced with a single batched query and an in-memory group. /api/insights/targets issued one findFirst per measurement type; replaced with a single distinct: ["type"] query. Same shape as the v1.3.0 fix to /api/insights/comprehensive.

Changed — Dashboard

• Tile strip is always one row. Replaces the wrapping grid-cols-2 sm:grid-cols-2 lg:grid-cols-4 xl:grid-cols-5 layout with a flex snap-x snap-mandatory overflow-x-auto strip. When the user enables more tiles than fit the viewport, the strip horizontal-scrolls instead of wrapping; the user trims the set in Settings → Dashboard Layout.

Added — Settings, integrations, and operations

• Settings page now lives at /settings/[section]. Eight focused routes (account, integrations, notifications, dashboard, ai, api, advanced, about) replace the single 3,000-line page. Existing /settings#anchor links 308-redirect; the side-bar, in-app deep links, and the AI / Withings / Codex callbacks all follow the new structure.
• About page lists the running version, build SHA, license, repository link, CHANGELOG link, docs link, and a "Check for updates" button that pings the public GitHub releases API. Backed by the /api/version endpoint shipped earlier in 1.4.0.
• Admin console is built around a status-first card grid (Users, Integrations, Monitoring, Backups, Maintenance, Audit Log) with each area in a focused panel beneath. Per-section extraction of the old inline panels is tracked for v1.4.1 — the v1.4.0 admin page already routes through the new aggregator endpoint and the status-card grid.
• Five new "Test connection" buttons in Settings. Withings, moodLog, Web Push, Glitchtip, and Umami now ship with one-click connection probes — same pattern as the existing AI / Telegram / ntfy tests, with per-button rate limit, sanitised error reporting, redirect-follow SSRF guard, and an errorCode in the response envelope so the UI can localise the message.
• AI insights can reference any of your charts inline. When a finding centres on a single metric (e.g. systolic blood pressure), the corresponding chart renders directly under the explanation. Server-side allow-list — only the allowed metric tokens render; any other model emission drops silently.
• Off-host backup target. Daily encrypted JSON dumps to any S3-compatible bucket. Worker-side IAM grant is intentionally PutObject + GetObject only — retention is the bucket's lifecycle-rule job, so a compromised worker cannot wipe the backup history. Restore script + step-by-step doc shipped under docs/ops/backup-restore.md, and an admin "Backup target" test button validates the configuration.
• Encryption-key versioning. Rotate the at-rest encryption key without downtime via pnpm tsx scripts/rotate-encryption-key.ts <id>. Existing data keeps decrypting under its original key while the new one is rolled out. Walk-through + rollback notes in docs/ops/encryption-key-rotation.md.
• Worker / web split. Optional HEALTHLOG_PROCESS_TYPE=web|worker|all (default all for the single-container setup) lets you scale background jobs and HTTP traffic independently. The proxy refuses HTTP traffic with a 503 + X-HealthLog-Process-Type: worker header in worker mode so a misrouted request fails loudly instead of a silent half-served response.
• Native API clients now get short-lived 24-hour access tokens with refresh-token rotation. The browser keeps the existing 90-day Bearer. Reuse-detection (presenting a refresh token a second time) revokes every refresh token for the user — the small cost of a forced re-login on the legitimate device buys defense-in-depth against an undetected stolen-token replay.
• Critical-path coverage on Telegram / Withings / moodLog / Glitchtip webhook handlers + the four admin routes lifted to ≥80% line coverage, plus src/lib/auth/audit.ts. ~+100 new tests.

Fixed — Operational hardening from the v1.4 review pass

• Container time zone is correct. Alpine images ship without tzdata; the daily backup cron 30 2 * * * Europe/Berlin was silently falling back to UTC. The runner stage now installs tzdata and exports TZ=Europe/Berlin so schedules fire at the documented local time.
• Compose healthcheck uses wget --spider /api/version — /api/version is now in the proxy's public-paths allowlist, so the healthcheck no longer 302-redirects through the auth gate (which was accepting the login page as a 200 success).
• Idempotency replay-cache no longer caches refresh tokens. The guard already blocked the hlk_ access-token prefix; the new hlr_ refresh tokens are blocked too.
• Logout-on-device revokes the paired access token. Calling /api/auth/refresh with revoke: true now flips both the refresh row and the matching ApiToken row to revoked, so a leaked access token cannot outlive its refresh-token sibling.
• users.locale migration drift backfilled. The column had been on schema.prisma since the v1.3 locale-aware reminder work but never landed in the migration history (it must have been applied via prisma db push to dev/prod). Any environment built strictly from prisma/migrations/ (CI testcontainers, brand-new self-host installs) is now consistent. Migration is ADD COLUMN IF NOT EXISTS, so it's a clean add on a fresh database and a safe no-op against any environment that was already kept in sync.

Notes

• Largely additive release. Existing API contracts (response envelopes, OpenAPI 3.1 spec) are unchanged. New endpoints surface optional fields; no breaking changes.
• New migration 0025_refresh_tokens adds the rotating refresh-token table; new migration 0025_user_locale_drift_fix backfills the schema-vs-migrations drift on users.locale. Both are forward-compatible — IF NOT EXISTS guards make them idempotent on any environment already pushed-to.
• Operators of the off-host backup feature must configure a bucket lifecycle policy for retention. The worker has no DeleteObject grant by design.
• Native API clients (iOS, n8n, Health Connect) need to update their login flow: native logins now return both a 24-hour access token and a refresh token. The browser flow is unchanged.
• Tracked for v1.4.1: per-section admin panel extraction (the status-card grid + aggregator already ship in 1.4.0; the inner per-section file split is structural cleanup), the Postgres-backed integration test suite (testcontainers infrastructure ships in this release; the four integration tests themselves need a follow-up pass against the merged schema), and Playwright E2E + axe-core CI gates.

[1.3.3] — 2026-05-08

Added

• Pulse oximetry as a first-class measurement type (OXYGEN_SATURATION). Closes the SpO2 part of #109. Migration 0024_oxygen_saturation extends the MeasurementType enum. Plausibility range 50–100% (below 50% is incompatible with sustained life and almost certainly a faulty sensor; upper bound 100% is physical). Default severity bands follow BTS Guideline 2017 + ATS clinical practice: green 95–100%, orange 92–94%, red <92% — lower-only concern (the upper orange wing collapses onto greenMax since saturation cannot physically exceed 100%). COPD / chronic-respiratory users with a doctor-set baseline of 88–92% can personalize via the threshold-override UI. Wired through Withings (ScanWatch type 54), measurement form, list, charts, doctor PDF, OpenAPI spec, and i18n (DE + EN). iOS DTO already declared OXYGEN_SATURATION from a prior commit; the server enum addition closes the long-standing drift.
• Body composition surfaces (TOTAL_BODY_WATER, BONE_MASS, BLOOD_GLUCOSE) in the measurements list filter, badge, mobile icon, edit dialog, and server-rendered doctor-report PDF — closes the UI side of #109. Root cause was three local maps in measurement-list.tsx that drifted from the v1.3 server enum; extracted to measurement-list-meta.ts with fail-fast coverage tests so future enum additions are caught at build time. Server-side PDF used a separately-drifted type map vs. the browser-side renderer; both are now in sync.
• Effective-range thresholds for TOTAL_BODY_WATER and BONE_MASS — severity logic was returning nominal for any value because no defaults existed.

Changed

• OpenAPI MeasurementType enum extended + spec version bumped 1.3.0 → 1.3.3 to match the actual app. Spec was lagging by two minor releases.
• Withings webhook secret now reads from X-Withings-Webhook-Secret header in preference to the legacy ?secret=… URL query parameter. Closes the URL-leak-via-access-logs vector flagged in audit C-3. Legacy query-param path is retained for backwards compatibility and emits a Wide Event warning so operators can spot still-using-the-old-flow integrators. Plan: remove the query fallback in 1.4.x once warnings drain.
• Idempotency defaultUserIdResolver now supports Bearer tokens. Cookie sessions tried first, then Bearer-token via hashToken lookup. Without the Bearer fallback, every iOS / external-ingest retry was hitting the handler again and creating duplicate measurements (audit C-4 — the exact use case withIdempotency was built for).
• GlitchTip URL stripping — reportToGlitchtip now strips the URL query string before forwarding so Withings legacy ?secret=… and OAuth ?code=… callbacks cannot leak via the error tracker (audit H-B7).

Fixed

• Migration 0022_body_composition_metrics unit comment lied — claimed TOTAL_BODY_WATER: percent of body weight (%) while every other surface (validators, Withings client, doctor PDF) treated it as kg. Comment corrected to match reality.

Security

• Bearer-scope wildcard handling (CRITICAL — V3-1). requireAuth() previously accepted any non-admin token regardless of declared permission scope, so a token with permissions:["medication:ingest"] could DELETE the user account. Spec now requires permissions:["*"] or the explicit required permission.
• Account-deletion completeness (CRITICAL — V3-2 / GDPR Art. 17). Cascades through Feedback + AuditLog rows so user-erasure is actually total. Daily retention job sweeps orphaned audit rows after 90 days as a defence-in-depth.
• Withings webhook secret header migration (audit C-3), idempotency Bearer-resolver (audit C-4), GlitchTip URL strip (audit H-B7).
• Truthfulness pass on medical citations — SpO2 normal-range source is now consumer-pulse-oximeter consensus + NICE NG115 + FDA labelling (BTS-2017 was for clinical hypoxaemia thresholds, not consumer monitoring); body-composition metrics are explicitly labelled "bioimpedance-estimated, not DEXA-comparable" in the doctor PDF; TBW citation now references the Watson formula / ICRP Reference Man (was misattributed to ESPEN 2017); steps target now references Saint-Maurice JAMA 2020 (WHO publishes minutes/week, not steps).
• SpO2 user-override clamp — overrides could emit physical impossibilities (e.g. orangeMax = 100.75); clamped to METRIC_BOUNDS for SpO2 + BODY_FAT.
• moodLog webhook secret encrypted at rest with AES-256-GCM (V3 STILL-V2-C-2). Read path tolerates legacy plaintext rows during the transition window; one-shot startup migration in the worker rotates any leftover plaintext rows.
• CSP tightening — chatgpt.com + api.openai.com connect-src now gated to /settings/ai/** (was a global blanket on every page, including /auth/login → DOM-XSS exfil channel).
• Web-Push subscription endpoint SSRF guard — endpoint now requires HTTPS + passes isPublicUrl() (was z.url() only). Side-fix: isPublicUrl() no longer falsely classifies DNS labels starting with fc/fd (e.g. fcm.googleapis.com) as IPv6 unique-local; the IPv6 check is now gated on a colon being present.
• IP-geolocation lookup is now HTTPS-only. Default provider is ipwho.is (free, HTTPS, no key). Existing ip-api.com plaintext HTTP path leaked auth-event IP + timestamp on every login (GDPR Art. 32 + Art. 44). Operators can override via IP_GEO_LOOKUP_URL (HTTPS only) or disable entirely with IP_GEO_LOOKUP_DISABLED=1.
• /api/ai/test no longer returns provider error message + body excerpt to the client. Diagnostics land server-side via Wide Events (annotate); client gets a categorised generic message. Closes provider URL / partial key / internal header leak.
• /api/import rate-limit added — 5 imports/hour/user. Was unlimited (bulk-injection vector).
• Trusted-proxy XFF semantics — getClientIp() now reads X-Forwarded-For right-to-left with a configurable TRUST_PROXY_HOPS (default 1, matches typical single-proxy self-host). Closes XFF rotation bypass of per-IP rate-limits.
• Audit-log retention job — audit_logs rows older than AUDIT_LOG_RETENTION_DAYS (default 365) are purged daily. Closes GDPR Art. 5(1)(e) "storage limitation" gap.
• Idempotency cachable-status filter is now an exported, unit-tested function — pins the do-not-cache contract for 401/403/408/429/5xx.
• Bearer mock tightening in require-auth-bearer.test.ts + idempotency.test.ts: apiToken.findUnique calls are now asserted to use where: { tokenHash: <hashed> }, so a regression to raw-token comparison would break the suite immediately.

Internal

• Server-side enum drift cousins closed. Five module-level hardcoded type-arrays in /api/insights/comprehensive, /api/dashboard/summary, /api/analytics, /lib/insights/general-status, /api/import are now derived from measurementTypeEnum.options. External-contract enums extended additively: /api/measurements/series (oxygen, totalBodyWater, boneMass), /api/dashboard/widgets (oxygenSaturation), DashboardWidgetId + DEFAULT_DASHBOARD_LAYOUT. New coverage test asserts the canonical enum stays the source of truth.
• Doctor-PDF text-content tests — replaced bytes-only "renders body composition rows" theatre with pdf-parse-driven assertions on the actual rendered DE + EN labels and values. Adds dev dep pdf-parse.

[1.3.2] — 2026-04-28

Fixed

• Glucose tiles on the dashboard rendered the raw i18n key targets.glucoseFasting instead of the translated label (closes #108). Both messages/en.json and messages/de.json had two top-level targets blocks; JSON.parse silently keeps the last occurrence, and that block was missing the four glucose labels. The duplicate is now collapsed into a single block. A duplicate bugreport.bugTitlePlaceholder shadowed inside bugreport was cleaned up too. Two further keys (dashboard.sleep, dashboard.steps) were missing from both locales and were falling back to hard-coded English; both are now translated.
• New i18n locale-integrity test (src/lib/__tests__/i18n-locale-integrity.test.ts) fails the build on duplicate keys at any nesting depth and on key drift between en and de — closes the structural gap that let the duplicate targets block ship in the first place.

Changed

• Screenshot upload removed from the bug-report form (also part of #108). The form previously accepted an image attachment that was stored in the local DB but never reached the published GitHub issue — GitHub does not accept inline base64 data URIs in issue bodies and offers no public API to attach images to an issue programmatically. Rather than ship misleading "a screenshot was attached" placeholder text in the resulting issue, the upload UI is now gone and the placeholder note is no longer added when promoting feedback. The screenshotBase64 column and the admin-side preview of previously-submitted screenshots are unchanged — existing reports keep their attachments locally. We plan to revisit a real screenshot pipeline in a future release.

[1.3.1] — 2026-04-27

Fixed

• Compose env-var validation no longer breaks Coolify-style deploys. docker-compose.yml previously used ${VAR:?required} shell-parameter syntax for the four secrets and POSTGRES_PASSWORD. Some hosting platforms (Coolify in particular) parse compose files eagerly and store the fallback error string ("POSTGRES_PASSWORD is required") as the literal env-var value when POSTGRES_PASSWORD was unset, which then collided with DATABASE_URL and broke the running app with P1000: Authentication failed. Compose now uses plain ${VAR} interpolation; validation moved into docker-entrypoint.sh, which fails fast with a clear stderr message listing the unset variables.

Notes

If you upgraded an existing Compose stack from 1.2.x → 1.3.0 and hit the POSTGRES_PASSWORD is required literal-as-value bug, set POSTGRES_PASSWORD in your environment to whatever your existing Postgres data volume was originally initialised with (likely healthlog if you started from a pre-1.2.1 release), then redeploy. Postgres only honours POSTGRES_PASSWORD on first volume init — the existing user keeps the original password regardless of env changes.

[1.3.0] — 2026-04-27

Added — Body composition + targeted hardening

• Total body water and bone mass as measurement types (closes #89). New enum values TOTAL_BODY_WATER and BONE_MASS, both stored canonically in kilograms (matches Withings hydration/bone-mass measures and Health Connect's TotalBodyWaterRecord / BoneMassRecord). Migration is purely additive (ALTER TYPE ... ADD VALUE) — safe to apply against any 1.2.x database without downtime.
• Withings sync picks both up automatically. The Withings client now maps measure type 77 (hydration / water mass) and 88 (bone mass). Anyone with a Withings Body+ scale and an active connection will see the new metrics flowing in on the next sync without any extra config.
• Doctor-report PDF includes both new types in the vital-signs table when data exists, with locale-aware labels in English and German.
• Dashboard widgets registered for both (default-invisible — opt in via Settings → Dashboard layout).

Security

• SSRF guard hardened (isPublicUrl). The previous implementation used parseInt with permissive prefix checks like h.startsWith("10.") which let 010.0.0.1 slip through — and worse, the WHATWG URL parser silently normalises 010.0.0.1 to 8.0.0.1 (octal interpretation), a real bypass on naive checks. The new guard adds a pre-URL leading-zero check on the raw input, a strict IPv4 parser, and proper IPv6 bracket / loopback / link-local handling. Now blocks 127.0.0.0/8, 0.0.0.0/8, 10.0.0.0/8, 169.254.0.0/16, 172.16.0.0/12, 192.168.0.0/16, 100.64.0.0/10 (CGNAT), ::1, fe80::/10, fc00::/7. Comprehensive regression tests included.
• GitHub PAT redacted from logged error bodies. When a feedback escalation to GitHub fails, the response body was being passed verbatim into getEvent()?.addWarning(...) — flowing to Loki. The body is now stripped of the configured token before logging.
• Per-user threshold writes are rate-limited (30 writes / 5 min) to make audit-log enumeration unattractive. Audit-logging itself was already there.

Performance

• N+1 in /api/insights/comprehensive fixed. The medication-compliance loop hit Postgres once per active medication. It now batches into a single medicationId IN (...) query and groups in memory. Latency improvement scales linearly with the user's active medication count.

Reliability

• pg-boss draining on SIGTERM/SIGINT. docker stop, Coolify redeploys, and Kubernetes pod terminations now trigger boss.stop({ graceful: true, timeout: 30s }) so in-flight handlers finish instead of being killed. Previously, pending handlers could be lost or replayed on restart.
• CI now blocks on TypeScript strict checks. continue-on-error: true removed for typecheck. Tests already were blocking. ESLint stays non-blocking for now — the existing settings/page.tsx monolith has long-standing react-hooks/set-state-in-effect violations whose proper fix lives in the 1.4.0 settings-split refactor; a blocking lint here would just gate every PR until that refactor lands. Required cleaning up two any types in api-handler.ts (justified inline — Next.js variadic handler signature constrained by Promise<Response> return).

Polish

• Bottom-nav touch targets sized to WCAG 2.5.5 minimum (44×44 CSS px). Visual icon stays at 20 px so the design doesn't shift.
• Phase-config dialog marks the decorative coloured dot aria-hidden because the redundant text label already conveys the phase to screen readers. No more meaningless image node announcements.
• Admin-status labels for "Web Push" and "Bug Report" now go through t() (new admin.integrationWebPush / admin.integrationBugReport keys in en + de). They were the last hard-coded English strings on the admin page.

What's not in this release (tracked for later)

• Onboarding redesign (dashboard-first empty-state flow + persistent Getting Started checklist) and the typed apiClient wrapper that underpins it are tracked for a focused 1.4.0 cycle. The 1.2.1 patch already closed the acute symptoms of #87 (silent-failure toast + default schedule), so the redesign is now a proper UI investment rather than a bug-fix.
• Withings sync is mapping both new measures, but a dedicated Bearer-auth ingest endpoint for external pipelines (n8n + Health Connect, requested in #89) ships in 1.4.0 alongside the API-token flow.

[1.2.1] — 2026-04-27

Fixed

• Onboarding: Medications added during onboarding are now actually persisted (closes #87). The wizard previously sent an empty schedules: [] array, the server-side validation rejected it with a 422, the client never checked response.ok, and the user was redirected to the dashboard as if everything had worked. Onboarding now wraps each step in try/catch, surfaces failures via toast, and attaches a default reminder window (08:00–09:00 daily) so the medication actually persists. A hint under the medication list explains the default.
• Docker setup (closes #88):
  • docker-compose.yml now uses ports: "3000:3000" (was expose: "3000", which made the app unreachable from the host).
  • POSTGRES_PASSWORD is a single env var that both the Postgres service and DATABASE_URL interpolate, so they cannot drift apart.
  • .env.example now points at the in-container hostname db:5432 (was localhost:5432, which never resolves inside the app container).
• Documentation:
  • package.json synced to 1.2.0 (was lagging on 1.1.0).
  • CLAUDE.md and AGENTS.md corrected to 23 models (the Feedback model added in v1.2 was missing from the count).
  • README.md Quick Start gives a realistic time estimate, generates the four secrets in one block straight into .env, and points reverse-proxy users at the docs.

Added — Tooling & Supply Chain

• Pre-built multi-arch images on GHCR: .github/workflows/docker-publish.yml now builds linux/amd64 + linux/arm64 images on every push to main and on every v* tag, publishing to ghcr.io/mbombeck/healthlog. Self-hosters no longer need a build toolchain — docker compose pull && docker compose up -d is enough. The bundled docker-compose.yml references the published image with a build: block as fallback for contributors.
• Supply-chain attestations: each published image carries a SLSA build provenance statement and a Software Bill of Materials. SECURITY.md documents how to verify them and how to pin a specific version.
• Documentation single source of truth: getting-started/installation.mdx is now the canonical setup guide (mirrors the bundled docker-compose.yml); self-hosting/docker.mdx slimmed to image internals + ops notes only. The landing page's Quick Start terminal block now includes the secrets-generation step (was missing).

Notes

This is a patch release that closes the install/onboarding friction reported in #87 and #88. The bigger user-facing changes (additional measurement types like total body water and bone mass per #89, full onboarding redesign, typed API client) are tracked for 1.3.0.

[1.2.0] — 2026-04-18

Added — Personalization, Glucose & Multi-Provider AI

• Per-user custom thresholds: Override the computed default ranges (BP, BMI, glucose, pulse) with values from your clinician. Audit-logged with previous/new values and timestamps. Doctor Report PDF flags custom ranges and prints both your target and the standard guideline value.
• Blood glucose tracking: New metric with fasting, postprandial, random, and bedtime contexts. Display unit switch between mg/dL and mmol/L (lossless conversion). Context-aware classification per ADA 2024 / DGIM. Per-context charting on dashboard and Doctor Report PDF.
• Dashboard customization: Show/hide and drag-to-reorder every dashboard widget. Per-user preference, reset-to-defaults button. Layout persists across the same user on the same device.
• Built-in feedback system: New in-app Send Feedback flow (Bug / Feature / Question / Other) with anonymized system info attachment. Stored in HealthLog's own database — no GitHub config required. Optional Escalate to GitHub button for admins who configure a PAT.
• Multi-provider AI insights: Provider abstraction extended with Anthropic Claude and local OpenAI-compatible endpoints (Ollama, LM Studio, vLLM, LiteLLM) alongside OpenAI. Per-user provider selection. Local endpoints keep all health data on your network.
• Locale-aware UI polish (English-first): Numbers, dates, glucose units, BP, weight, and BMI all formatted via useFormatters() from the active locale. Doctor Report PDF and AI insight prompts now respect locale end-to-end (no hand-rolled Intl.* with fixed locales).

Changed

• Reference range computation extracted into a dedicated src/lib/health/thresholds.ts module with computed defaults and override resolution.
• AI provider routing reworked to dispatch by provider field on the user record; OpenAI remains the default for legacy users.
• Dashboard route renders widgets from UserDashboardLayout model when present, otherwise falls back to the default order.
• Doctor Report PDF: locale-aware headers, glucose section, custom-range badges.

Security

• GitHub PAT for feedback escalation stored AES-256-GCM encrypted in the database (never as env var).
• Local AI endpoint URLs validated against SSRF (no localhost/RFC1918 unless explicitly allowed by admin).
• Custom threshold writes rate-limited and audit-logged with IP.
