+# Changelog
+
+All notable changes to temetro are recorded here. The format is loosely based on
+[Keep a Changelog](https://keepachangelog.com/), and the project follows
+[Semantic Versioning](https://semver.org/). See [RELEASING.md](./RELEASING.md)
+for how releases are cut and published.
+
+## [Unreleased]
+
+### Added
+- **Version & update awareness.** `GET /api/version` reports the running version
+  and checks GitHub Releases for a newer one; Settings → **About & updates** shows
+  the current/latest version, and an optional, dismissible banner appears when an
+  update is available.
+- **LAN access.** The frontend now resolves the backend URL from the host the
+  browser is using, so other departments can reach temetro at
+  `http://<server-LAN-IP>:3000` with no rebuild. A Settings panel surfaces the
+  shareable network address. `GET /api/network` reports detected LAN addresses.
+- **Prebuilt Docker images** published to Docker Hub (`khalidxv/temetro-backend`,
+  `khalidxv/temetro-frontend`) via a tag-triggered GitHub Actions release workflow.
+- **Voice dictation** on the AI chat input (Web Speech API), with graceful
+  fallback where the browser doesn't support it.
+
+### Changed
+- `docker-compose.yml` references the published images (with a build fallback) and
+  no longer bakes a fixed API URL into the frontend.
+
+## [0.1.0] — 2026-06-26
+
+Initial baseline: clinician AI-chat UI wired to the TypeScript/Express/Postgres
+API (Better Auth, multi-tenant clinics, org-scoped patient records), the patient
+wallet encrypted-share flow, and Dockerised local run.

+## Patient wallet app (sibling repo `~/Desktop/temetro-app`)
+
+The **patient companion app** is its own git repo on the Desktop (not in this monorepo): an **Expo
+SDK 56** app whose UI **must be built with HeroUI Native** (`heroui-native` + Uniwind/Tailwind) — a
+hard requirement; the one exception is the native tab bar, which uses expo-router `NativeTabs`. See
+its `CLAUDE.md`. It stores the patient's record **encrypted on-device**,
+the patient's identity is an **Ed25519 keypair** whose public key (base58check, `tmw_…`) is their
+**wallet number**, and it shares records by sealing them to a clinic's ephemeral key over the
+backend relay. The crypto wire format mirrors `backend/src/lib/wallet-crypto.ts` exactly. "Decentralization"
+here means keys + data live on the patient's device and the relay only ever forwards ciphertext — it
+is **not** a literal blockchain (records are off-chain, which is also what lets a temporary share be
+deleted). Commit/push that app inside its own repo, separately from this one.

-information, displayed as rich record cards.

-## Monorepo layout
+![temetro AI chat](./.github/assets/screenshot-chat.png)
 
-This repository is a **monorepo** containing two independent apps that live side by side (each with
-its own `package.json` / `node_modules` and its own `CLAUDE.md`):
+</div>
 
-- **[`frontend/`](./frontend)** — the Next.js 16 product app (the clinician-facing AI chat UI).
-  See [`frontend/CLAUDE.md`](./frontend/CLAUDE.md).
-- **[`backend/`](./backend)** — the Express 5 + Postgres API (Drizzle ORM + Better Auth).
-  See [`backend/CLAUDE.md`](./backend/CLAUDE.md) and [`backend/README.md`](./backend/README.md).
+## What is temetro?
 
-The marketing **landing page lives in its own separate repository** (`temetro-landing`), not here.
+temetro is a clinical tool that puts a **natural-language AI chat** between
+clinicians and patient records. Instead of clicking through tabs, a clinician
+asks for what they need and temetro returns organized **record cards** —
+vitals, labs, medications, problems, encounters — with trend sparklines and
+detail views.
 
-## Run locally with Docker (recommended)
+Its distinguishing idea is a **patient-owned data model**. Instead of (or
+alongside) living only in a doctor's database, a patient's record can live on
+the **patient's own device**. When a clinician adds or changes data they
+**sign** it (blockchain-style); the change is written to the patient's record
+and **cannot be modified until the patient approves it** through a companion
+wallet app. temetro can also **read existing patient databases** and present
+them in the same card UI.
 
-Docker Compose builds and runs Postgres, the backend, and the frontend together. From the
-**`backend/`** directory (the Compose file builds the sibling `../frontend`):
+> "Decentralization" here means keys and data live on the patient's device and
+> the relay only ever forwards ciphertext — it is **not** a literal blockchain.
+> Records are off-chain, which is what lets a temporary share be deleted.
+
+## Features
+
+- 🗂️ **AI chat over patient records** — `/patient <file#>` (or natural language)
+  renders the record as cards with sparklines and detail dialogs.
+- 🔐 **Auth & multi-tenant clinics** — email/password + staff usernames,
+  organizations, and role-based access (owner / admin / doctor / reception /
+  pharmacy / lab) via [Better Auth](https://better-auth.com).
+- 🩺 **Full clinical surface** — patients, appointments, prescriptions, tasks,
+  doctor's notes, pharmacy inventory, analytics, an activity audit log,
+  real-time staff messaging, and notifications.
+- 📲 **Patient wallet & encrypted share** — a companion app holds the record
+  encrypted on-device; clinics import records over an end-to-end encrypted,
+  patient-approved relay (with optional auto-deleting temporary shares).
+- 🌐 **Works across the clinic LAN** — open it on the server or from any
+  department's computer at `http://<server-IP>:3000`; no per-machine config.
+- 🔄 **Self-update awareness** — the app tells admins when a newer release is
+  out and how to update.
+
+## Quick start (Docker)
+
+The fastest path uses the **prebuilt images** published to Docker Hub. From the
+[`backend/`](./backend) directory (it holds the Compose file):
 
 ```bash
 cd backend
-cp .env.example .env
-
-# generate a strong auth secret and paste it into BETTER_AUTH_SECRET in .env:
-openssl rand -base64 32
-
-docker compose up --build
+docker compose pull        # fetch the latest published images
+docker compose up -d       # start Postgres + backend + frontend
 ```
 
-Then open:
+No `.env` or secret setup is required — the backend generates and persists any
+missing secrets on first start. Then open:
 
-- Frontend → http://localhost:3000
-- Backend → http://localhost:4000 (health check: `GET /health`)
-- Postgres → localhost:5432
+- **Frontend** → http://localhost:3000
+- **Backend** → http://localhost:4000 (health: `GET /health`)
 
-Database migrations are applied automatically on backend container start.
+Prefer to **build from source** (for development)? Use `docker compose up
+--build` instead. Migrations apply automatically on backend start.
 
-**Port conflict?** If another Postgres already holds host port `5432`, set `POSTGRES_PORT` (e.g.
-`5433`) in `backend/.env`. The app still talks to Postgres internally on `db:5432`; only the
-published host port changes.
+> **Port conflict?** If another Postgres holds host port `5432`, set
+> `POSTGRES_PORT` (e.g. `5433`) in `backend/.env`. The app still talks to
+> Postgres internally on `db:5432`; only the published host port changes.
 
-Run just the API + database with `docker compose up db backend`. To browse the database with
-Adminer: `docker compose --profile tools up adminer` → http://localhost:8080.
+### Access from other computers (hospital LAN)
 
-## Run locally without Docker
+temetro figures out the backend address from the host you open it on, so other
+departments can simply visit **`http://<server-LAN-IP>:3000`** — no rebuild
+needed. Settings → **About & updates** shows the exact shareable address. The
+server's firewall must allow ports `3000`/`4000`.
 
-Run each app in its own terminal (you'll need a local Postgres reachable from `DATABASE_URL`):
+### Updating
+
+```bash
+docker compose pull && docker compose up -d
+```
+
+The app surfaces a notification when a newer release exists. See
+[`CHANGELOG.md`](./CHANGELOG.md) for what changed and [`RELEASING.md`](./RELEASING.md)
+for how releases are built and published.
+
+## Run without Docker
+
+Each app runs independently (you'll need a local Postgres in `DATABASE_URL`):
 
 ```bash
 # backend
-cd backend
-npm install
-cp .env.example .env        # point DATABASE_URL at your local Postgres
-npm run db:migrate          # apply migrations
-npm run dev                 # http://localhost:4000
+cd backend && npm install && cp .env.example .env
+npm run db:migrate && npm run dev      # http://localhost:4000
 
 # frontend (second terminal)
-cd frontend
-npm install
-npm run dev                 # http://localhost:3000
+cd frontend && npm install && npm run dev   # http://localhost:3000
 ```
 
-The frontend reads `NEXT_PUBLIC_API_URL` (default `http://localhost:4000`) to reach the backend.
+> With `SMTP_HOST` unset, verification / reset / invitation emails are **printed
+> to the backend console** — no email setup needed for local development.
 
-> If `SMTP_HOST` is unset, verification / reset / invitation emails are **printed to the backend
-> console** instead of being sent — no email setup is needed for local development.

+# Releasing temetro
+
+temetro is self-hosted: clinics run it with Docker and update by pulling new
+images. Each release publishes prebuilt images to Docker Hub and cuts a GitHub
+Release; the running app checks that release feed to tell admins an update is
+available. This document is the checklist for cutting one.
+
+## Versioning
+
+We follow [Semantic Versioning](https://semver.org/) — `MAJOR.MINOR.PATCH`,
+starting at **0.1.0**. The canonical version lives in the root
+[`package.json`](./package.json); `backend/package.json` and
+`frontend/package.json` track the same number. `GET /api/version` reports it.
+
+## One-time setup
+
+Add these repository secrets (GitHub → Settings → Secrets and variables →
+Actions) so the release workflow can publish:
+
+| Secret | What |
+| --- | --- |
+| `DOCKERHUB_USERNAME` | Docker Hub account with push access to the `khalidxv` namespace |
+| `DOCKERHUB_TOKEN` | A Docker Hub access token for that account |
+
+Images are published as `khalidxv/temetro-backend` and `khalidxv/temetro-frontend`.
+
+## Cutting a release
+
+1. **Bump the version** in `package.json`, `backend/package.json`, and
+   `frontend/package.json` to the new `X.Y.Z`.
+2. **Update [`CHANGELOG.md`](./CHANGELOG.md)**: move the `Unreleased` notes under a
+   new `## [X.Y.Z] — <date>` heading.
+3. **Commit** the bump (`chore(release): vX.Y.Z`).
+4. **Tag and push**:
+   ```bash
+   git tag vX.Y.Z
+   git push origin main --tags
+   ```
+5. The **`release` workflow** (`.github/workflows/release.yml`) then:
+   - builds and pushes both images tagged `X.Y.Z` **and** `latest`, and
+   - creates a **GitHub Release** with auto-generated notes.
+
+That GitHub Release is what the in-app update check compares against, so update
+notifications light up for everyone on an older version once it's published.
+
+## How clinics update
+
+On the server machine, from the directory holding `docker-compose.yml`:
+
+```bash
+docker compose pull && docker compose up -d
+```
+
+This pulls the new `latest` images and restarts. Pin a specific version with
+`TEMETRO_VERSION=X.Y.Z docker compose up -d`. Updating is optional — the in-app
+banner just makes it discoverable.

+## Scope
+
+temetro handles clinical data. Reports in the following areas are treated as high priority:
+
+- Authentication or session bypass
+- Unauthorized access to patient records across clinic tenants
+- Data injection (SQL, XSS, command injection)
+- Exposure of credentials or secrets
+
+## Out of scope
+
+- Vulnerabilities in dependencies that have already been publicly disclosed and are pending an upstream fix
+- Theoretical issues with no practical exploit path
+- Issues in the patient companion app or blockchain signing layer (not yet built)

-This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+# temetro frontend
 
-## Getting Started
+The clinician-facing **AI chat UI** for [temetro](../) — a Next.js 16 app where
+clinicians retrieve and organize patient data in natural language, rendered as
+rich record cards. It's wired to the [`../backend`](../backend) for real auth,
+multi-tenant clinics, and live patient data.
 
-First, run the development server:
+![temetro AI chat](../.github/assets/screenshot-chat.png)
+
+## Stack
+
+Next.js 16 (App Router) · React 19 · TypeScript · Tailwind CSS v4 ·
+[COSS](https://coss.dev) UI components (Base UI) · i18next · Socket.io client.
+
+> This app runs a **customized Next.js 16** whose conventions differ from the
+> public docs (e.g. route protection lives in `proxy.ts`, not `middleware.ts`).
+> See [`CLAUDE.md`](./CLAUDE.md) and `node_modules/next/dist/docs/` before
+> writing Next.js code.
+
+## Develop
 
 ```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
+npm install
+npm run dev      # Next dev server (Turbopack) on http://localhost:3000
 ```
 
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+Other scripts: `npm run build` (production build), `npm run start` (serve the
+build), `npm run lint`. There is no test runner — verify changes by running the
+dev server.
 
-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+### Talking to the backend
 
-This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+The frontend needs the API running (see [`../backend`](../backend)). It resolves
+the backend URL **from the host you open the app on** — so it works on
+`localhost` and across the clinic LAN (`http://<server-IP>:3000`) without a
+rebuild. Set `NEXT_PUBLIC_API_URL` only to pin a fixed or reverse-proxied URL;
+see [`lib/backend-url.ts`](./lib/backend-url.ts).
 
-## Learn More
+## Architecture
 
-To learn more about Next.js, take a look at the following resources:
+- **`app/`** — App Router. `app/(app)/` is the authenticated product shell;
+  `app/(auth)/` holds the login / signup / onboarding pages.
+- **`components/chat/`** — the chat UI (input, message state, patient cards).
+- **`components/settings/`** — settings panels, including **About & updates**
+  (version + LAN access).
+- **`components/ui/`** — COSS primitives (Base UI, added via the shadcn CLI).
+- **`lib/`** — API + auth clients, i18n, and data helpers.
