fix: QR wallet pairing broken by multi-clinic routing (v0.8.1)

QR "scan to connect" pairing has no wallet number, so nothing registered
the request with the relay and the scanning device's response was rejected
("unknown or expired request"). The backend now pre-registers the pairing
request over the relay's new hub:expect event on POST /pair, and
re-registers still-pending requests on hub (re)connect so routing survives
a relay restart. /pair now requires the clinic to have joined the network
(clear 409, surfaced in the import dialog, localized in all five langs).

+## [Unreleased]
+
+## [0.8.1] — 2026-07-05
+
+### Fixed
+- **QR "scan to connect" pairing** was broken by the multi-clinic relay routing (v0.8.0): pairing
+  has no wallet number, so the clinic never sent a `wallet:send` to register the request, and the
+  relay rejected the scanning device's response as "unknown or expired". The clinic now
+  **pre-registers** the pairing request with the relay (a new `hub:expect { requestId }` event on
+  `POST /api/patients/wallet/pair`), so the device's response routes back correctly. On hub
+  (re)connect the backend re-registers its still-pending requests, so routing also survives a relay
+  restart. `POST /pair` now also requires the clinic to have joined the network (clear 409 instead of
+  a dead QR), surfaced in the import dialog.
+
+### Added
+- **Multi-clinic Temetro Network.** The relay now serves many self-hosted clinics at once. Each
+  clinic authenticates to the `/hub` namespace by **signing a challenge with its own Ed25519 clinic
+  signing key** (`services/signing.ts`) — a per-clinic identity, not a shared password — and the
+  relay routes every device response back to only the clinic that originated the request (keyed by
+  `requestId`), so clinics never see each other's traffic. `wallet:online` is fanned out only to
+  clinics with pending work for that wallet.
+- **"Join Temetro Network" opt-in.** A per-clinic toggle in **Settings → Signing** (backed by
+  `clinic_signing_keys.network_enabled`, `GET`/`PUT /api/signing/network`, owner/admin only). Off by
+  default; enabling opens the clinic's relay connection, disabling tears it down. Wallet
+  import/push endpoints return **409** while a clinic hasn't joined. Localised in all five languages.
+
+### Changed
+- **The backend keeps one authenticated relay connection per network-enabled org**
+  (`services/relay-client.ts` — `connectOrg`/`disconnectOrg`, a `hubs` map keyed by `orgId`), instead
+  of a single shared-token connection. `emitToWallet`/`sendToWallet` now take an `orgId`, and the
+  offline-flush (`pendingUpdatesForWallet`) is org-scoped.
+- **`RELAY_TOKEN` is now optional/legacy.** Clinics authenticate with their signing key, so an open
+  relay needs no shared secret; `RELAY_TOKEN` only gates an optional *private* relay.
+
+## [0.7.0] — 2026-07-05
+
+### Added
+- **Temetro Network** — a standalone, high-performance **relay** (Rust + Axum + socketioxide) that
+  connects the backend to patient wallet apps, in its own repo
+  ([github.com/temetro/temetro-network](https://github.com/temetro/temetro-network)) and deployable
+  on Railway. It replaces the flaky Cloudflare quick-tunnel that used to expose the backend's
+  embedded `/wallet` Socket.io namespace to phones. The relay is a **dumb, stateless pipe**: a
+  `/wallet` namespace for devices (challenge/Ed25519-signature auth, room keyed by wallet number)
+  and a `RELAY_TOKEN`-authenticated `/hub` namespace for the backend. It forwards sealed ciphertext
+  verbatim, keeps no database, and its only crypto is verifying a device's auth signature (proven
+  byte-for-byte compatible with `wallet-crypto.ts`).
+
+### Changed
+- **The backend is now a client of the relay, not the wallet server.** The `/wallet` Socket.io
+  namespace was removed from `src/realtime.ts`; a new `src/services/relay-client.ts` connects to the
+  relay's `/hub` (`emitToWallet` delegates to its `sendToWallet`), handles device responses
+  (`wallet:share-response` / `wallet:update-response` / `wallet:revoke`) and flushes missed updates on
+  `wallet:online` — calling the same `wallet-share` / `wallet-updates` services as before. New
+  `RELAY_URL` + `RELAY_TOKEN` env vars; the wallet-import QR now points at `RELAY_URL`.
+
+## [0.6.0] — 2026-07-04
+
+### Added
+- **Read-only FHIR R4 server** — temetro can now be a FHIR **server**, not just a client.
+  A new endpoint tree at **`/fhir`** (mounted outside `/api`, bearer-only) exposes each
+  clinic's records as FHIR R4: **Patient**, **Observation** (labs + synthesized vital signs),
+  **AllergyIntolerance**, **Condition**, **MedicationRequest**, **Encounter** and
+  **Appointment**, plus an unauthenticated **`GET /fhir/metadata`** CapabilityStatement.
+  Searches return searchset `Bundle`s with `_count`/`_offset` pagination and self/next/prev
+  links. Because temetro stores free-text clinical values, every `CodeableConcept` is
+  **text-only** (no SNOMED/LOINC) and patients carry an **age** extension rather than a
+  `birthDate` — documented in the CapabilityStatement and API docs.
+- **Per-clinic FHIR API keys** — machine-to-machine auth via `Authorization: Bearer tmf_…`.
+  Keys are created/revoked under **Settings → Integrations → FHIR server** (owner/admin),
+  **SHA-256-hashed** at rest, and shown **once** at creation. Every FHIR request is
+  org-scoped (no cross-clinic reads) and written to the activity log with the key name and
+  result count. New `fhir_api_keys` table, `middleware/fhir-auth.ts`, the
+  `services/fhir-server/` mapping module (queries, resources, bundle, capability, keys), the
+  `/fhir` router, and `GET/POST/DELETE /api/integrations/fhir-server/keys`. New `fhirServer`
+  locale namespace across all five languages.
+
+## [0.5.0] — 2026-07-03
+
+### Added
+- **Clinic → wallet record-update push** — a clinician can push an updated record to a
+  **wallet-linked** patient (a permanent, approved share). The record snapshot is **signed**
+  with the clinic's Ed25519 key and **sealed** to the wallet's X25519 key (derived from its
+  Ed25519 wallet number via the birational map — verified byte-for-byte against the wallet's
+  own derivation), stored `pending`, and delivered over the `/wallet` relay live **and** on
+  the wallet's next authenticated connect (so an offline phone catches up). The patient
+  reviews it in a **pending-updates inbox** and approves/denies; the wallet signs its
+  decision, the backend verifies it, and the on-device record is replaced only on approval.
+  The wallet **pins** the clinic key (TOFU) and warns on a key change. New
+  `POST /api/patients/wallet/push`, `GET /api/patients/wallet/{link/:fileNumber,updates,updates/:id}`,
+  `walletRecordUpdates` table + service, `wallet:update-request` / `wallet:update-response`
+  relay events, a "Push to wallet" dialog with live status, and a "Sent updates" list under
+  Settings → Signing. New `walletPush` / `walletUpdatesList` locale namespaces across all five
+  languages. (The wallet app half ships in the sibling `temetro-app` repo.)
+
+## [0.4.0] — 2026-07-03
+
+### Added
+- **Ambient AI visit scribe** — a **Record visit** action on the patient sheet turns a
+  clinician↔patient conversation into a draft **SOAP** encounter note. Record with the
+  microphone (`MediaRecorder`, stored as an auditable patient attachment) or paste a
+  transcript; the backend transcribes via the user's **OpenAI (Whisper)** or **Gemini**
+  key, de-identifies the transcript + patient context through **Veil**, and the model
+  drafts a structured note that the clinician **reviews and edits before saving** — the
+  same write-approval gate as the chat agent. New `POST /api/scribe/{transcribe,draft,save}`
+  (`backend/src/routes/scribe.ts`, `services/ai/transcribe.ts`), a `veil.redactText()`
+  free-text redactor, and an `appendEncounter` service that adds one note without touching
+  the rest of the record. Gated by `patient:write` + the clinic AI policy (reception and
+  disabled-AI accounts don't see it). New `scribe` locale namespace across all five
+  languages. Drafting also works with local Ollama from a pasted transcript.
+
+## [0.3.0] — 2026-07-02
+
+### Added
+- **Three new interface languages** — Somali (`so`), Arabic (`ar`) and German
+  (`de`) join English and French, selectable in Settings → Profile → Language.
+  Each locale carries a full translation of the ~1,660 UI strings, with native
+  names shown in the selector (Soomaali, العربية, Deutsch).
+- **Right-to-left (RTL) support** — selecting Arabic sets `dir="rtl"` on the
+  document (applied before first paint via an inline script, so no flash), flips
+  physical spacing/alignment to logical CSS utilities, mirrors directional icons,
+  and loads an Arabic-capable typeface (IBM Plex Sans Arabic) appended to the
+  font stack for per-character fallback.
+- **Language roams across devices** — the chosen language is persisted to the
+  per-user `user_settings` preferences and re-applied on sign-in, with
+  localStorage remaining the offline source of truth.
+- **`frontend/scripts/check-locales.mjs`** (+ `npm run check-locales`) — a parity
+  check that fails on missing/extra keys or `{{placeholder}}` mismatches across
+  locales and warns when Arabic count-keys lack the full CLDR plural forms.
+
+## [0.2.5] — 2026-07-01
+
+### Fixed
+- **Multi-arch Docker images** — the `release` workflow now builds and publishes
+  `khalidxv/temetro-backend` and `khalidxv/temetro-frontend` for both
+  `linux/amd64` and `linux/arm64`. Previously the images were amd64-only, so
+  `docker compose pull` on Apple Silicon failed with *no matching manifest for
+  linux/arm64/v8* and fell back to building from source.
+
+### Changed
+- **Language switcher** in Settings → Profile is now a **select** that asks for
+  confirmation before switching the interface language, instead of applying the
+  change instantly on a button tap.
+
+## [0.2.4] — 2026-06-29
+
+### Added
+- **Pagination** on the Activity and Invoices pages (10 per page), matching the
+  Patients page, via a shared `ListPagination` component.
+- **French (Français)** interface language, with a language switcher in
+  Settings → Profile. The choice persists on the device.
+- **"Check for updates"** button in Settings → About & updates that forces a
+  fresh check.
+
+### Changed
+- **Update detection** now reads the latest version from **Docker Hub** image
+  tags (the channel clinics actually pull), falling back to the GitHub release
+  if Docker Hub is unreachable. This fixes "About & updates" showing *Up to
+  date* when a newer image was already published.
+- **docker compose** host ports are now configurable (`BACKEND_PORT`,
+  `FRONTEND_PORT`, `ADMINER_PORT`, alongside `POSTGRES_PORT`) so a port clash on
+  `docker compose up -d` can be resolved from `.env` without editing the file.
+
+## [0.2.3] — 2026-06-29
+
+### Fixed
+- **AI chat patient record cards** now render on Google Gemini for name
+  lookups. "Show me <name>'s medical record" relied on the model chaining
+  `searchPatients` → `getPatient`, but Gemini often called `searchPatients`
+  and then emitted only a canned closing line ("Here's the record.") without
+  the second tool call — so no card was ever drawn. `searchPatients` now
+  displays the record card directly when exactly one patient matches, so the
+  flow no longer depends on a follow-up tool call. (The previous Gemini fix in
+  0.2.2 only covered the empty-schema list tools.)
+
+## [0.2.2] — 2026-06-28
+
+### Fixed
+- **AI chat record cards** now render on Google Gemini. The card-emitting
+  chat tools (`listAppointments`, `listTasks`, `listPrescriptions`,
+  `getClinicInfo`, `getAnalytics`, `listInventory`) used an empty parameter
+  schema; Gemini can't emit a function call for a schema with no properties,
+  so it printed the call as `tool_code` text instead of invoking the tool —
+  leaving replies as plain text (e.g. "Show today's schedule" leaked a raw
+  `<tool_code>` block) with no cards. The tools now share a non-empty schema
+  so Gemini calls them; other providers are unaffected.
+
+## [0.2.1] — 2026-06-27
+
+### Fixed
+- **Patients pagination** controls now render as proper buttons — the prev/next
+  and page-number controls were unstyled and wrapping (the COSS `PaginationLink`
+  drops its button styling when given a `render` prop).
+- **Patient detail sheet header** reflowed: actions (Download summary / Transfer
+  / Edit / Delete) moved to their own wrapping row so the patient name is no
+  longer truncated.
+- **Messages thread** now shows **sender and recipient avatars** alongside the
+  chat bubbles.
+- **Release notes** — the `release` workflow now publishes the matching
+  `CHANGELOG.md` section as the GitHub Release body (instead of only the
+  auto-generated "Full Changelog" link).
+
+## [0.2.0] — 2026-06-27
+
+### Added
+- **Patients table pagination.** The Patients list now paginates at 10 rows per
+  page (COSS `Pagination`), so large clinics no longer scroll endlessly.
+- **Per-patient record history.** The patient detail sheet shows an audit
+  timeline of every add/change on that chart. `GET /api/activity/patient/:fileNumber`.
+- **Patient summary PDF.** A **Download summary** action on the patient sheet
+  produces a clean, printable one-page clinical summary (browser "Save as PDF").
+- **AI setup notice.** A single, dismissible heads-up appears above the chat
+  input on a fresh chat when no AI provider (API key or local Ollama) is
+  configured; it clears itself once you send a message.
+- **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
+- **Messages thread** rebuilt on the shadcn `Message` / `Bubble` / `Attachment`
+  components (COSS colour tokens preserved) for a cleaner conversation surface.
+- **Patient status badges** now use semantic colours (active → success,
+  inpatient → info) instead of a flat secondary badge.
+- `docker-compose.yml` references the published images (with a build fallback) and
+  no longer bakes a fixed API URL into the frontend.
+
+### Fixed
+- **AI import approval card.** `previewImport` now declares a concrete record
+  schema so Google Gemini emits a real tool call (and the approval card renders)
+  instead of dumping a `tool_code`/JSON wall as text. The system prompt also
+  forbids printing tool calls and re-listing fields.
+- **Settings network address** no longer shows a bogus container IP / "Error"
+  under Docker — the `/api/network` endpoint now skips container-internal
+  interfaces, and the panel falls back to the helpful LAN hint.
+
+## [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.
+
+## Temetro Network (sibling repo/folder `~/Desktop/Temetro-network`)
+
+The **relay** that connects this backend to patient wallet apps. It is its **own git repo** on the
+Desktop (folder `~/Desktop/Temetro-network`, pushed to `github.com/temetro/temetro-network`), **not**
+in this monorepo — a standalone **Rust + Axum + socketioxide** service meant to run always-on (e.g.
+on **Railway**). It replaces the old flaky Cloudflare quick-tunnel that used to expose the backend's
+embedded `/wallet` Socket.io namespace to phones.
+
+It is a **dumb, stateless pipe**: two Socket.io namespaces — `/wallet` for devices
+(challenge/Ed25519-signature auth, room keyed by wallet number) and `/hub` for this backend
+(`RELAY_TOKEN`-authenticated). Devices and the backend both connect to it; it **forwards sealed
+ciphertext verbatim** and never opens bundles or touches a database. Its only crypto is verifying a
+device's auth signature (mirrors `backend/src/lib/wallet-crypto.ts`). The backend connects to it as a
+`/hub` client via `backend/src/services/relay-client.ts` (its `sendToWallet` is what `emitToWallet`
+now calls); configure with `RELAY_URL` + `RELAY_TOKEN`. Commit/push that service inside its own repo,
+separately from this one.

-**temetro** is an **open-source** clinical tool that acts as an **AI middleman** between clinicians
-and patient data. Clinicians use a natural-language AI chat to retrieve and organize patient
-information, displayed as rich record cards.
+**An open-source AI middleman between clinicians and patient data.**
 
-Its distinguishing idea is a **patient-owned data model**: instead of (or alongside) living in a
-doctor's own database, a patient's record can be stored 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 app.
-temetro can also **read existing patient databases** and present them in the same organized card UI.
+Clinicians ask in plain language; temetro retrieves and organizes patient
+information as rich record cards — backed by a **patient-owned data model**.
 
-> **Status.** The **backend is built** — a TypeScript + Express + Postgres API (Drizzle ORM) with
-> authentication and multi-tenant clinics via [Better Auth](https://better-auth.com), an org-scoped
-> patient records API, plus appointments, prescriptions, tasks, doctor's notes, analytics, an
-> activity audit log, real-time staff messaging (Socket.io), and notifications. The **frontend chat
-> is wired to it** (real auth, route protection, clinic switching, live patient data).
->
-> **Still vision, not built:** the patient companion app and the blockchain-style
-> **signing / patient-owned storage / approval** flow, and the AI chat replies themselves (currently
-> mock — no LLM call yet; a `/chat` endpoint is the next planned step).

-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 host ports `5432`, `4000` or `3000` are already in use,
+> set `POSTGRES_PORT`, `BACKEND_PORT` and/or `FRONTEND_PORT` (e.g. `5433` /
+> `4001` / `3001`) in `backend/.env`. The services still talk to each other on
+> their internal ports (`db:5432`, `backend:4000`); only the published host
+> ports change.
 
-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.
+## Monorepo layout
+
+Two independent apps live side by side, each with its own `package.json` and
+`CLAUDE.md`:
+
+- **[`frontend/`](./frontend)** — Next.js 16 product app (the AI chat UI).
+- **[`backend/`](./backend)** — Express 5 + Postgres API (Drizzle ORM + Better
+  Auth). See [`backend/README.md`](./backend/README.md) for the API reference.
+
+The **patient wallet app** and the **marketing landing page** live in their own
+separate repositories.

+# 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.
