Subject: [PATCH] E-Mail-Versand von SMTP auf mailto-Weiterleitung umgestellt
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Server-seitiger SMTP-Versand (Zugangsdaten, /api/email/senden, /api/email/test)
vollständig entfernt und durch mailto: ersetzt: PDF wird lokal generiert und
heruntergeladen, danach öffnet sich das E-Mail-Programm des Nutzers mit
vorausgefülltem Empfänger. Vorbereitung für die Docker-Containerisierung, da
dort nur ein Admin (der Betreiber) existiert und die Lösung ohne
rollenspezifische Ausnahmen für jedes Konto gleichermassen funktionieren muss.

 - **Auth**: session-cookie based. `_get_current_user()` / `_check_admin()` read `session["nutzer_id"]`; `login_required` / `admin_required` decorators guard individual routes, while `global_auth_check()` (a Flask `before_request` hook) blanket-blocks any `/api/*` path not in the small public allowlist (`/api/auth/login`, `/api/auth/me`, `/api/einstellungen/public`). Two roles exist: `admin` and `nutzer`. Passwords are hashed with `werkzeug.security` (PBKDF2).
 - **Patient isolation**: `patienten.nutzer_id` (FK to `nutzer.id`) records who owns each patient — set automatically to the creating user on `POST /api/patienten`. Two helpers in `app.py` enforce it everywhere: `_get_owned_patient(pid)` (single-patient routes — returns the row if the current user is the owner or an admin, else `None` → caller returns 404) and `_scope_sql(column="id")` (list/aggregate routes — returns a SQL fragment + params to append to a `WHERE` clause; empty for admins, `AND {column} IN (SELECT id FROM patienten WHERE nutzer_id=?)` otherwise). `admin` role is exempt and always sees every patient. Every route touching `patienten` or a child table (`antraege`, `leistungen`, `aufgaben`, `pflegetagebuch`, `dokumente`) must go through one of these two helpers — when adding a new patient-scoped route, follow the existing pattern rather than querying the table directly. `aufgaben.patient_id` is nullable in the schema, but the API now requires a `patient_id` from non-admin callers on creation (admins may still create patient-less tasks) so the isolation model stays consistent between write and read paths.
 - **File storage**: everything is local under `static/` — `static/fotos/<patient_id>.<ext>` (profile photos), `static/briefe/<patient_id>/…` (generated letter PDFs), `static/dokumente/<patient_id>/…` (uploaded documents), `static/logo/` (company branding). No object storage/CDN involved.
-- **Settings**: a generic key-value `einstellungen` table (accessed via `get_setting()`) holds SMTP credentials, company branding/address, and an (unused-in-current-flow) Claude API token — surfaced through `/api/admin/einstellungen`.

 - Frontend: `curAbo`/`aboBlockiert` globals are set in `initApp()` from `GET /api/abo/status`. `go(name)` redirects any navigation to the `meinabo` page while `aboBlockiert` is true, so a blocked account always lands on its own status/pay screen instead of a broken page. `pgMeinAbo()` is that page (status, price, stub PayPal button) and doubles as the always-available "check my subscription" view when unblocked.
 - When actually integrating PayPal: replace `/api/abo/aktivieren`'s stub body with real Checkout/Subscription creation, add a webhook endpoint to update `abo_bis`/`abo_typ` on payment events, and only then flip `abo_pflicht` to `"1"`.
 
+## Email: mailto hand-off, not SMTP
+
+There is **no server-side email sending anywhere in the app** — no SMTP client, no credentials, no relay. This was a deliberate removal (not a missing feature) done ahead of Docker containerization, because post-Docker the operator (Daniel) is the sole admin with no per-role differentiation to lean on — any email solution had to work identically for every account, not just an admin-configured one. `mailto:` is the "universal command": every OS/browser resolves it to the user's own default mail client (iOS → Mail, Android → Gmail/Outlook/whatever is set as default, desktop → whatever is set as default), with zero server involvement and zero secrets to manage in the container.
+
+- Previously removed: `smtplib`/`email.mime.*` imports, `_smtp_cfg()`, `_smtp_send()`, `POST /api/email/senden`, `POST /api/email/test`, the "E-Mail (SMTP)" Backend-Einstellungen card, and the `email_smtp_*` settings keys. None of this exists anymore — don't resurrect it as a "fallback"; the user explicitly chose full removal over keeping SMTP as a backup path.
+- Frontend flow (`sendMailModal(typ)` / `sendMail(typ)` in `templates/index.html`, shared by both Musterbrief and Widerspruch-Generator via the `typ` parameter): the modal collects Empfänger/Betreff/Anschreiben, then on send the existing client-side `html2pdf.js` PDF generation runs exactly as it already did for the plain "PDF herunterladen" button (`dlW()`/`dlM()`) — the blob is downloaded to the user's device **and** persisted to the patient's Akte via `POST /api/patienten/<pid>/briefe` — then `location.href='mailto:'+to+'?subject=...&body=...'` opens the user's mail client with recipient/subject/body pre-filled.
+- **Hard limitation, not a bug**: `mailto:` cannot carry attachments — this is a browser/OS security restriction, not something this app can work around. The email body includes a bracketed reminder ("Bitte die heruntergeladene Datei „…" anhängen, dann diese Zeile löschen") and the modal's info box explains the same thing before sending, so the manual-attach step is expected UX, not a silent gap.
+- If you add a third document type that needs "send by email", follow the same pattern: reuse the existing PDF-blob-download code for that document, then call the same `mailto:` construction — don't reintroduce a server-side send path.
+
 ## Demo account
 
 A permanent `demo`/`demo` account (`nutzer.ist_demo=1`) exists for showing the app to prospects, created automatically in `init_db()` if missing. It's a completely ordinary `nutzer`-role account — no special-casing in the isolation model — with two exceptions layered on top:
 
 - **Immune to the subscription paywall**: `_hat_aktiven_zugang()` returns `True` for `ist_demo` accounts unconditionally, *before* the `abo_pflicht` check. Don't remove this — a demo visitor must never see "Zahlung erforderlich" regardless of the operator's billing settings. (This was caught by testing, not designed in from the start — worth re-checking if `_hat_aktiven_zugang()` is ever refactored.)
-- **Cannot send real email**: `POST /api/email/senden` and `/api/email/test` both return 403 for `ist_demo` accounts, so a demo visitor can never trigger outbound mail through the operator's real SMTP relay.
+- **Email is a non-issue for the demo account**: since email sending was migrated to the client-side `mailto:` hand-off (see "Email: mailto hand-off, not SMTP" below), there is no server-side outbound relay left to abuse — a demo visitor's "send" click only opens *their own* local mail client via a `mailto:` link, never the operator's infrastructure. The earlier 403 block on `/api/email/senden`/`/api/email/test` for `ist_demo` accounts was removed along with those routes; no replacement guard was needed.
 
 **Auto-reset every 6 hours**, lazily rather than via a background thread/cron (this app has no task scheduler and stays that way — a lazy check fits the existing "one Flask process, no queue" architecture and can't miss a tick across restarts): `_demo_reset_faellig()` compares the `einstellungen` key `demo_reset_at` against `now`; `_demo_reset()` deletes every patient owned by the demo account (cascades to antraege/leistungen/aufgaben/pflegetagebuch/dokumente via the existing `ON DELETE CASCADE` FKs — SQLite enforces this because `get_db()` sets `PRAGMA foreign_keys = ON`), then reseeds one fictional pre-filled patient (`_demo_seed()`: "Grete Musterfrau", Pflegegrad 3, one Antrag, two Leistungen, two Aufgaben, one Pflegetagebuch-Eintrag) and bumps `demo_reset_at`. The check/reset call happens in two places — `api_auth_login()` (fresh state at the start of every demo session) and `global_auth_check()` (catches a session that's still open when the 6h boundary passes mid-visit) — both call the same `_demo_reset_faellig()`/`_demo_reset()` pair, so there's one source of truth for "is a reset due."
