 HealthLog is a self-hosted health tracking app (PWA + native iOS client) that runs from a single `docker compose up` on a NAS, homelab, or small VPS. It brings weight, blood pressure, pulse, blood glucose, body composition, sleep, mood, menstrual cycle, and medications onto one timeline — synced from the devices you already own — and keeps everything encrypted at rest on hardware you control. No vendor cloud, no subscription, no telemetry.
 
+HealthLog is a personal health record-keeping and wellness tool. It is not a medical device and does not diagnose, treat, cure, or prevent any disease — it helps you log, visualise, and export your own data, and leaves clinical judgement to a clinician.

 ## Highlights
 
-- **Every vital on one timeline.** Weight, blood pressure, pulse, glucose, body composition, sleep, SpO₂, mood, and cycle tracking — charted with trends, moving averages, and clinical reference ranges (ESH 2023, ADA 2024), overridable with the targets your clinician set.
+- **Every vital on one timeline.** Weight, blood pressure, pulse, glucose, body composition, sleep, SpO₂, respiratory rate, mood, and cycle tracking — charted with trends, moving averages, and clinical reference ranges (ESH 2023, ADA 2024), overridable with the targets your clinician set.
+- **Clinical signals, opt-in and additive.** Validated mental-wellbeing self-checks (PHQ-9, GAD-7) that sit beside mood tracking with calm crisis-resource handling, grip strength, a 0–10 pain score, waist and body measurements, and a longevity lab panel — each added through one signal registry, so a new signal wires into charts, correlations, the coach, the FHIR map, and the API at once.
+- **Records and the documents you're handed.** Structured allergies and family history (encrypted), lab values you key in or scan, and inbound documents — discharge letters and reports — read to extract the facts they state (values, codes, dates) for you to review and confirm. HealthLog transcribes what a document says; it never interprets or diagnoses from it. (Immunization records are deliberately out of scope.)
+- **Context that explains the numbers.** An opt-in environmental module folds weather, daylight, and temperature in as influence signals (winter darkness against mood, heat against blood pressure) using a home location you set, so a pattern has somewhere to point.
 - **Your devices, one server.** Withings, WHOOP, Oura and Polar sync over OAuth2, Fitbit connects experimentally over the Fitbit Web API, an Apple Health `export.zip` folds your full history in, and the native iOS app streams HealthKit live. A per-metric source priority decides which reading is canonical when wearables overlap.
 - **Medication tracking that tells the truth.** Flexible schedules (weekly injections, weekday-only, intervals, PRN, cyclic), a configurable intake window per dose, and a traceable dose history where every slot reads taken, late, skipped, or missed — the same ledger the compliance rate is computed from, so the percentage can never disagree with the timeline.
-- **AI insights you own.** Daily briefing, health scores, correlations, and a conversational coach grounded in your own measurements, with proactive check-ins. Bring your own OpenAI or Anthropic key, or point at a local endpoint (Ollama, LM Studio, vLLM) so nothing leaves your network.

The coach describes your data, never diagnoses. Bring your own OpenAI or Anthropic key, or point at a local endpoint (Ollama, LM Studio, vLLM) so nothing leaves your network.
 - **Clinician-ready output.** A doctor-report PDF generated client-side, a read-only HL7 FHIR R4 API, and scoped, time-limited share links you revoke after the visit.
 - **Private by construction.** AES-256-GCM encryption at rest with zero-downtime key rotation, passkey login, server-side sessions, strict CSP — and no third-party tracking anywhere.
 - **Built to be lived in.** Installable PWA with offline support, medication reminders over APNs, Telegram, ntfy, and Web Push, a sub-second dashboard on years of imported history, English and German end to end.

+## What the Coach is — and isn't
+
+The Coach is an informational assistant that works from your own
+logged data. It is not a doctor, what it says is not medical advice,
+and it does not diagnose, prescribe, or change treatment — those
+boundaries are written into its system prompt as safety contracts, not
+left to chance. It describes patterns observationally ("your resting
+heart rate has been rising over 14 days"), never as a verdict about a
+named condition, and it defers diagnosis, dose, and drug-interaction
+questions to a healthcare professional. This is HealthLog's
+project-wide self-description standard: a personal health
+record-keeping and wellness tool, not a medical device. The same
+non-diagnostic framing governs the daily briefing, the insights, and
+every surface that turns your data into words.
+
+The Coach can also reach out proactively — a calm, once-a-day morning
+check-in when there is something genuine to surface (a recovery trend
+easing off, blood pressure running a touch high). The nudge is warm
+and localized, references the focus by category rather than quoting
+your own words back, and stays silent when there is nothing real to
+say or when you have engaged the Coach recently. It is an invitation,
+never a streak-guilt prompt, and it inherits the same non-diagnostic
+boundaries as the chat.

+21. Describe HealthLog honestly when asked what you are, what this app is,
+    or where the user's data goes. HealthLog is a self-hosted personal
+    health record-keeping and wellness tool — it helps the user log,
+    visualise and export their OWN data. It is NOT a medical device and does
+    NOT diagnose, treat, cure or prevent any disease; you are an
+    informational assistant, not a doctor, and what you offer is not medical

+    encrypted at rest; AI runs on a provider key they bring or a local
+    model, so nothing leaves their instance beyond the provider they
+    configured, and there is no third-party analytics on their health data.
+    State this plainly and calmly when relevant; never oversell it as
+    confidential like a clinician's, and keep deferring diagnosis /
