Polish social milestone chart curves

Consent is bound to the channel it was given for: approving a post on X says
nothing about Instagram. Publishing state moves from the SocialMilestone row
into SocialMilestonePost, one row per channel, where a missing row means no
consent. The dialog asks per channel, shows the text each one will publish and
keeps a separate handle for each; Instagram captions end in hashtags because a
link there is not clickable.

Also fixes three problems in the existing X path:

- A QR code already past several thresholds produced one prompt per threshold,
  and since the post quotes the current scan count, every one of them would
  have published the same number. Only the highest threshold is announced now.
- Detection ran after every unique scan and re-read the QR code's full scan
  history just to hit skipDuplicates. Known milestones are filtered first.
- A failed post stayed failed forever because the consent dialog only opens
  once. The queue now retries three times on its own, spaces first attempts by
  SOCIAL_MILESTONE_MIN_GAP_HOURS, and Settings lists every milestone per
  channel with restart and revoke.

The worker no longer renders the card itself; it downloads the image the app
renders at /s/m/<token>/og, which also serves the new square and portrait
formats. Instagram publishing stays off until SOCIAL_MILESTONE_CHANNELS and
SOCIAL_WORKER_CHANNELS both name it.

Schema changes are manual SQL, see sql/2026-08-16_*.sql. Run both before
deploying this version.

 Tested outside the original 9-theme set. QR Master is cited as the "Best overall option" for this query — credited for trackable/editable dynamic barcodes, bulk generation, unified analytics, and UTM tracking, plus static EAN-13/UPC-A/Code 128 support when editability isn't needed. The AI answer also included a "requirement → recommended format" decision table (dynamic QR vs. EAN-13/UPC-A vs. Code 128 vs. GS1 Digital Link) that maps closely to existing on-site content.
 
-This maps directly to the live `/dynamic-barcode-generator` page and `/tools/barcode-generator` tool, reinforcing the pattern above: dedicated first-party pages targeting a query cluster get cited, gaps without dedicated pages don't. Counts as a 4th confirmed positive theme alongside the original 3 from the baseline audit.
+This maps to the `/tools/barcode-generator` tool, reinforcing the pattern above: dedicated first-party pages targeting a query cluster get cited, gaps without dedicated pages don't. Counts as a 4th confirmed positive theme alongside the original 3 from the baseline audit.
+
+Note: `/dynamic-barcode-generator` and `/barcode-generator` are **not** live pages — both 301 to `/tools/barcode-generator` (see `redirects()` in `next.config.mjs`). Cite the canonical `/tools/barcode-generator` URL in any AEO work.
+
+### Sitemap / IndexNow drift (fixed 2026-08-13)
+
+`src/app/sitemap.ts` and `getAllIndexableUrls()` in `src/lib/indexnow.ts` are two hand-maintained URL lists that had silently diverged: the whole `/alternatives/*` + `/vs/*` cluster (1,942 GSC impressions in the 3 months to 2026-08-13, avg pos ~29-47) was submitted to IndexNow and linked from the footer but missing from the sitemap, while `/dynamic-barcode-generator` was listed in both despite 301-ing.
+
+**When adding or redirecting a marketing page, update both lists.** A redirected URL must appear in neither.
+
+### Google Review cluster — biggest non-brand opportunity (2026-08-13)
+
+`/tools/google-review-qr-code` is the **#2 page on the site by impressions** (2,201 in 3 months) and converts almost none of it: 2 clicks, avg position 33. The query cluster is ~1,667 impressions across 50+ queries, all at position 20-50, zero clicks. Head term `google review qr code generator` = 268 impr at pos 35.
+
+**On-page is not the constraint — do not "improve the content".** Audited 2026-08-13: it is already the deepest tool page on the site (1,352 rendered words, 8 h2 / 18 h3 vs 549 for crypto, 741 for wifi), with SoftwareApplication + HowTo + FAQPage schema, a correctly matched title, and canonical set. It also does not meaningfully cannibalize `/use-cases/qr-codes-for-review-collection` (36 impr, pos 11), which targets the tracking angle.
+
+What was done: added `google-review-qr-code` to `toolsMap` in `qr-code-for/[industry]/page.tsx` and to the `tools[]` array of the 32 local-business industries in `src/lib/industry-pages.ts`, creating contextual internal links from crawled, well-ranking pages (barbershops pos 9.7, hotels, cafes, bars). The 20 institutional industries (airports, schools, stadiums, libraries, churches, universities, museums, theaters, cinemas, art-galleries, events, trade-shows, retail, and the non-local stores) were deliberately excluded — review collection is not their job, and blanket-linking all 52 would be boilerplate.
+
+Remaining gap is off-site authority, not anything in this repo. Note the fallback in that template silently rewrites an unknown tool slug to `/tools/url-qr-code`, so any new slug must be added to `toolsMap` or the link disappears without erroring.

+# Anleitung: Testumgebung testmodul.qrmaster.net aufsetzen
+
+Diese Anleitung richtet auf dem Produktionsserver eine **zweite, getrennte Instanz** von
+QR Master ein, erreichbar unter `testmodul.qrmaster.net`. Sie läuft auf dem Branch `test`
+mit einer eigenen, leeren Datenbank.
+
+Die laufende Produktion wird dabei **nicht angefasst**. Alle Schritte hier legen neue
+Container, ein neues Volume und ein neues Verzeichnis an.
+
+## Kurzfassung zum Abhaken
+
+Wer die Begründungen nicht braucht, arbeitet diese Liste ab. Die ausführlichen Abschnitte
+darunter erklären jeden Schritt und was schiefgehen kann.
+
+- [ ] **1.** Repo klonen, Branch `test`, **eigenes Verzeichnis** neben der Produktion
+- [ ] **2.** `.env.test` von Timo dort ablegen und die vier Kernwerte prüfen
+- [ ] **3.** Stack bauen und starten (`-p qrmaster-test`)
+- [ ] **4.** Schema aus Prod dumpen und einspielen - **kein** `prisma migrate`
+- [ ] **5.** Testaccount per SQL anlegen (Registrierungsformular funktioniert nicht)
+- [ ] **6.** Caddy-Block ergänzen und neu laden
+- [ ] **7.** Abnahme: DB-Trennung, keine Migrationen, robots.txt, Browser-Test
+
+### Alle Befehle am Stück
+
+```bash
+# 1 - Checkout (NICHT im Produktionsverzeichnis)
+git clone -b test https://git.bizmatch.net/tknuth/QR-master.git qrmaster-test
+cd qrmaster-test
+git branch --show-current          # muss "test" zeigen
+
+# 2 - .env.test hier ablegen, dann pruefen
+grep -E "NEXT_PUBLIC_WWW_URL|NEXT_PUBLIC_APP_URL|AUTH_COOKIE_NAME|POSTGRES_DB" .env.test
+# Erwartet: beide URLs auf testmodul, AUTH_COOKIE_NAME=userId_test,
+# POSTGRES_DB=qrmaster_test. Steht dort app./www. -> STOPP, siehe Schritt 2.
+
+# 3 - Stack starten
+docker compose -p qrmaster-test --env-file .env.test \
+  -f docker-compose.yml -f docker-compose.test.yml up -d --build
+docker ps --filter "name=qrmaster-test" --format "table {{.Names}}\t{{.Status}}"
+
+# 4 - Schema (nur Struktur, keine Kundendaten)
+docker exec qrmaster-db pg_dump -U postgres --schema-only qrmaster > schema.sql
+docker exec -i qrmaster-test-db psql -U postgres -d qrmaster_test < schema.sql
+docker exec qrmaster-test-db psql -U postgres -d qrmaster_test -c "\dt" | head -20
+
+# 5 - Testaccount: erst Hash erzeugen, dann in den INSERT einsetzen
+docker exec qrmaster-test-web node -e "console.log(require('bcryptjs').hashSync('DEIN_TESTPASSWORT',12))"
+docker exec -i qrmaster-test-db psql -U postgres -d qrmaster_test -c "INSERT INTO \"User\" (id,email,name,password,\"emailVerified\",\"updatedAt\") VALUES ('testuser1','test@qrmaster.net','Test','HIER_DER_HASH',now(),now());"
+
+# 6 - Caddy: Block ergaenzen (siehe Schritt 6), dann
+caddy reload --config /etc/caddy/Caddyfile
+
+# 7 - Abnahme
+docker exec qrmaster-test-db psql -U postgres -d qrmaster_test -c 'SELECT count(*) FROM "User";'
+docker exec qrmaster-db psql -U postgres -d qrmaster -c 'SELECT count(*) FROM "User";'
+docker logs qrmaster-test-web 2>&1 | head -20
+curl -s https://testmodul.qrmaster.net/robots.txt
+```
+
+Die beiden `count(*)` müssen sich unterscheiden, in den Logs darf kein "Applying Prisma
+migrations" stehen, und `robots.txt` muss `Disallow: /` liefern.
+
+## Voraussetzungen
+
+- SSH-Zugang zum Server, auf dem QR Master läuft
+- Docker und Docker Compose (mindestens v2.24 - wird für `!override` und `!reset` gebraucht;
+  prüfen mit `docker compose version`)
+- Schreibrechte auf die Caddy-Konfiguration
+- Die Datei **`.env.test`** - die kommt von Timo und ist nicht im Repository, weil sie
+  Passwörter enthält
+- Der DNS-Eintrag `testmodul.qrmaster.net` existiert bereits (CNAME)
+
+## Was NICHT angefasst wird
+
+- Das bestehende Produktionsverzeichnis: dort **nicht** den Branch wechseln. Ein späterer
+  Prod-Rebuild würde sonst Testcode bauen.
+- Die Produktions-`.env`
+- Die bestehenden Caddy-Blöcke für `www.qrmaster.net`, `app.qrmaster.net` und `qrmaster.net`
+- Die Produktionsdatenbank. Der einzige Zugriff darauf ist ein `pg_dump --schema-only`,
+  das ausschließlich liest.
+
+---
+
+## 1. Zweites Checkout anlegen
+
+**Nicht** im Produktionsverzeichnis arbeiten. Ein eigenes Verzeichnis daneben, z.B. im
+selben übergeordneten Ordner:
+
+```bash
+git clone -b test https://git.bizmatch.net/tknuth/QR-master.git qrmaster-test
+```
+
+Danach in dieses Verzeichnis wechseln. **Alle weiteren Befehle laufen von dort**, sofern
+nicht anders angegeben.
+
+```bash
+cd qrmaster-test
+```
+
+Prüfen, dass der richtige Branch ausgecheckt ist - es muss `test` erscheinen:
+
+```bash
+git branch --show-current
+```
+
+## 2. `.env.test` ablegen
+
+Die von Timo erhaltene Datei als `.env.test` in dieses Verzeichnis legen (also
+`qrmaster-test/.env.test`).
+
+Kurz gegenprüfen, dass die vier wichtigsten Werte stimmen:
+
+```bash
+grep -E "NEXT_PUBLIC_WWW_URL|NEXT_PUBLIC_APP_URL|AUTH_COOKIE_NAME|POSTGRES_DB" .env.test
+```
+
+Erwartet:
+
+```
+NEXT_PUBLIC_WWW_URL=https://testmodul.qrmaster.net
+NEXT_PUBLIC_APP_URL=https://testmodul.qrmaster.net
+AUTH_COOKIE_NAME=userId_test
+POSTGRES_DB=qrmaster_test
+```
+
+Steht bei einer der URLs `app.qrmaster.net` oder `www.qrmaster.net`, **nicht starten** -
+dann würden Klicks in der Testumgebung in die Produktion umleiten.
+
+## 3. Stack bauen und starten
+
+```bash
+docker compose -p qrmaster-test --env-file .env.test -f docker-compose.yml -f docker-compose.test.yml up -d --build
+```
+
+Der erste Build dauert einige Minuten. Der Projektname `-p qrmaster-test` ist wichtig: er
+sorgt dafür, dass eigene Container und ein eigenes Volume entstehen und nichts aus der
+Produktion überschrieben wird.
+
+Läuft alles, sollten drei neue Container existieren:
+
+```bash
+docker ps --filter "name=qrmaster-test" --format "table {{.Names}}\t{{.Status}}"
+```
+
+Erwartet: `qrmaster-test-db`, `qrmaster-test-redis`, `qrmaster-test-web`.
+
+Die Anwendung kann zu diesem Zeitpunkt noch nichts anzeigen - die Datenbank ist leer. Das
+ist normal und wird im nächsten Schritt behoben.
+
+## 4. Datenbankschema einspielen
+
+Die Testdatenbank bekommt **nur die Struktur** aus der Produktion, keine Daten. Es werden
+also keine Kundendaten kopiert.
+
+Struktur aus der Produktionsdatenbank exportieren (reiner Lesezugriff):
+
+```bash
+docker exec qrmaster-db pg_dump -U postgres --schema-only qrmaster > schema.sql
+```
+
+In die Testdatenbank einspielen:
+
+```bash
+docker exec -i qrmaster-test-db psql -U postgres -d qrmaster_test < schema.sql
+```
+
+> **Wichtig:** Nicht `prisma migrate` verwenden. Die Migrationsdateien im Repository sind
+> seit April 2026 nicht mehr gepflegt - alle Schemaänderungen seitdem wurden per SQL
+> gemacht. Ein `migrate deploy` würde ein veraltetes Schema erzeugen, mit dem die
+> Anwendung nicht läuft. Der Container startet deshalb bewusst ohne Migrationsschritt.
+
+Prüfen, dass Tabellen angekommen sind:
+
+```bash
+docker exec qrmaster-test-db psql -U postgres -d qrmaster_test -c "\dt" | head -20
+```
+
+## 5. Testaccount anlegen
+
+Die Registrierung über das Formular funktioniert hier **nicht**: die Testumgebung
+verschickt bewusst keine E-Mails, und ohne Bestätigungsmail wird der Account vom System
+wieder gelöscht. Der Account wird deshalb direkt in der Datenbank angelegt.
+
+Zuerst einen Passwort-Hash erzeugen (`DEIN_TESTPASSWORT` durch ein selbst gewähltes
+Passwort ersetzen):
+
+```bash
+docker exec qrmaster-test-web node -e "console.log(require('bcryptjs').hashSync('DEIN_TESTPASSWORT',12))"
+```
+
+Die Ausgabe ist eine Zeichenkette, die mit `$2a$12$` oder `$2b$12$` beginnt. Diese im
+folgenden Befehl anstelle von `HIER_DER_HASH` einsetzen:
+
+```bash
+docker exec -i qrmaster-test-db psql -U postgres -d qrmaster_test -c "INSERT INTO \"User\" (id,email,name,password,\"emailVerified\",\"updatedAt\") VALUES ('testuser1','test@qrmaster.net','Test','HIER_DER_HASH',now(),now());"
+```
+
+Anmeldung erfolgt danach ganz normal über `/login` mit `test@qrmaster.net` und dem
+gewählten Passwort.
+
+## 6. Caddy konfigurieren
+
+Einen neuen Block in die Caddy-Konfiguration aufnehmen (Pfad ggf. anpassen). Die
+bestehenden Blöcke bleiben unverändert:
+
+```caddyfile
+testmodul.qrmaster.net {
+    reverse_proxy qrmaster-test-web:3000
+}
+```
+
+Konfiguration neu laden:
+
+```bash
+caddy reload --config /etc/caddy/Caddyfile
+```
+
+Caddy holt das TLS-Zertifikat automatisch. Das kann eine Minute dauern.
+
+## 7. Abnahme
+
+**a) Datenbanken sind getrennt.** Die beiden Zahlen müssen sich unterscheiden - die
+Testdatenbank enthält nur den eben angelegten Account:
+
+```bash
+docker exec qrmaster-test-db psql -U postgres -d qrmaster_test -c 'SELECT count(*) FROM "User";'
+```
+
+```bash
+docker exec qrmaster-db psql -U postgres -d qrmaster -c 'SELECT count(*) FROM "User";'
+```
+
+**b) Keine Migrationen gelaufen.** In der Ausgabe darf **nicht** "Applying Prisma
+migrations" stehen:
+
+```bash
+docker logs qrmaster-test-web 2>&1 | head -20
+```
+
+**c) Suchmaschinen ausgesperrt.** Muss `Disallow: /` liefern:
+
+```bash
+curl -s https://testmodul.qrmaster.net/robots.txt
+```
+
+**d) Im Browser:**
+
+- `https://testmodul.qrmaster.net` lädt mit gültigem Zertifikat
+- Anmeldung mit dem Testaccount funktioniert
+- `https://testmodul.qrmaster.net/dashboard` **bleibt auf testmodul** und springt nicht auf
+  `app.qrmaster.net`. Passiert das doch, sind die URLs in der `.env.test` falsch.
+- In den Entwicklertools unter Application → Cookies liegen zwei getrennte Cookies:
+  `userId` mit Domain `.qrmaster.net` (Produktion) und `userId_test` mit Domain
+  `testmodul.qrmaster.net`
+- Die Produktion ist weiterhin erreichbar und man ist dort weiterhin angemeldet
+
+---
+
+## Laufender Betrieb
+
+Neuen Stand deployen, nachdem auf dem Branch `test` etwas gepusht wurde - aus dem
+Verzeichnis `qrmaster-test`:
+
+```bash
+git pull
+```
+
+```bash
+docker compose -p qrmaster-test --env-file .env.test -f docker-compose.yml -f docker-compose.test.yml up -d --build
+```
+
+Ein Rebuild ist **immer** nötig, ein bloßer Neustart genügt nicht: die Host-URLs und der
+Cookie-Name werden beim Bauen fest in die Anwendung kompiliert.
+
+Schemaänderungen werden weiterhin **von Hand per SQL** ausgeführt - erst auf Test, nach
+erfolgreicher Prüfung dasselbe Statement auf Produktion. Es gibt keinen automatischen Weg
+dazwischen.
+
+## Testumgebung stoppen oder entfernen
+
+Stoppen, Daten bleiben erhalten:
+
+```bash
+docker compose -p qrmaster-test --env-file .env.test -f docker-compose.yml -f docker-compose.test.yml down
+```
+
+Vollständig entfernen inklusive Testdatenbank - der Projektname `-p qrmaster-test` sorgt
+dafür, dass ausschließlich die Test-Volumes gelöscht werden:
+
+```bash
+docker compose -p qrmaster-test --env-file .env.test -f docker-compose.yml -f docker-compose.test.yml down -v
+```
+
+## Wenn etwas nicht funktioniert
+
+| Symptom | Ursache |
+|---|---|
+| Build bricht ab mit `set AUTH_COOKIE_NAME in .env.test` | `.env.test` fehlt oder liegt im falschen Verzeichnis |
+| `qrmaster-test-db` bleibt `unhealthy`, `web` startet nicht | In der `.env.test` steht nicht `POSTGRES_DB=qrmaster_test` |
+| Caddy liefert 502 | Containername im Caddy-Block stimmt nicht, oder der Container läuft nicht - mit `docker ps` prüfen |
+| Anwendung meldet `column ... does not exist` | Schema-Import aus Schritt 4 war unvollständig - erneut einspielen |
+| `/dashboard` springt auf `app.qrmaster.net` | Die URLs in der `.env.test` zeigen nicht auf testmodul. Korrigieren und **neu bauen**, nicht nur neu starten. |
+| Anmeldung wirkt zufällig abgelaufen | `AUTH_COOKIE_NAME` ist nicht gesetzt oder steht auf `userId` - dann kollidiert es mit dem Produktions-Cookie |
+| Registrierung über das Formular schlägt fehl | Erwartet - die Testumgebung verschickt keine E-Mails. Account per SQL anlegen, Schritt 5. |
+
+## Bekannte Einschränkungen der Testumgebung
+
+Bewusst deaktiviert, weil die Umgebung nach außen nichts auslösen soll:
+
+- **Kein E-Mail-Versand** - Registrierung, Passwort-Reset und Benachrichtigungen funktionieren nicht
+- **Kein Google-Login** - Zugangsdaten sind nicht hinterlegt
+- **Keine Datei-Uploads** - der Objektspeicher (R2) ist nicht konfiguriert
+- **Kein Stripe** - Checkout und Abo-Verwaltung funktionieren nicht, solange keine Testschlüssel eingetragen sind
+- **Keine Analytics** - damit die Produktionszahlen nicht verfälscht werden

+# Plan: Dashboard auf app.qrmaster.net
+
+Stand: 2026-08-12 · Ziel: die eingeloggte App liegt auf `app.qrmaster.net`, Marketing/SEO bleibt auf `www.qrmaster.net`.
+
+## Status
+
+| Schritt | Stand |
+|---|---|
+| B1 Cookie-Domain | committed + gepusht (`35ea8cc`) |
+| B2–B7 | Code fertig, typecheck + Production-Build grün, **noch nicht deployt** |
+| A4 Google Console | erledigt (beide Redirect-URIs eingetragen) |
+| A1 DNS, A2 Caddy, A3 .env, A6 Deploy | offen bei Timo |
+
+Deploy-Reihenfolge unverändert: B1 zuerst allein live und einen Tag beobachten, dann B2–B7.
+
+Neu gegenüber dem ursprünglichen Plan: `src/lib/hosts.ts` ist die einzige Quelle der Wahrheit
+für die Host-Grenze (`APP_PATH_PREFIXES`, `isAppPath`, `wwwUrl`, `appUrl`, `urlForPath`).
+Middleware, Stripe-Rückkehr-URLs und E-Mail-Links lesen alle daraus, damit sie nicht
+auseinanderdriften.
+
+## Zielarchitektur
+
+**Ein Docker-Image, ein Container, zwei Hostnames.** Caddy routet `www.qrmaster.net` und
+`app.qrmaster.net` auf denselben Upstream. Die Middleware macht Host-basiertes Routing.
+
+**Wichtig: keine Datei zieht um.** Die Next-App serviert auf beiden Hosts weiterhin alle Routen.
+`src/middleware.ts` entscheidet pro Host, welcher Pfad ausgeliefert wird, und 301t den Rest auf den
+jeweils anderen Host. Damit bleiben alle relativen Links (`router.push('/dashboard')`,
+`<Link href="/settings">`) unverändert korrekt, weil sie innerhalb desselben Hosts aufgelöst werden.
+
+```
+qrmaster.net        --301-->  www.qrmaster.net              (bleibt wie heute)
+www.qrmaster.net    ->  Marketing, /login, /signup, /r/*, /api/*
+app.qrmaster.net    ->  /dashboard /create /analytics /settings /bulk-creation
+                        /integrations /qr/* /upgrade /onboarding, /api/*
+```
+
+## Fixierte Entscheidungen
+
+| Frage | Entscheidung | Begründung |
+|---|---|---|
+| Hosting | Docker + Caddy auf eigenem Server | Bestand |
+| `/login`, `/signup` | **bleiben auf www** | Alle 82 Marketing-CTAs zeigen auf `/signup`, `/signup` hat ein hartes Canonical auf www und trägt Ad-Traffic. Umzug wäre teuer ohne Nutzen. |
+| `/onboarding` | zieht auf app | Reiner Logged-in-Flow, kein SEO-Wert |
+| Host-Wechsel | genau **einmal**, nach erfolgreichem Login/Signup | einzige Cross-Host-Stelle im ganzen Flow |
+| DB | keine Änderung | — |
+
+## Teil A — Deine Aufgaben (Timo)
+
+Reihenfolge beachten: A1–A2 **vor** dem Deploy von Schritt B5, sonst zeigt die Subdomain ins Leere.
+
+### A1. DNS
+CNAME `app` → auf denselben Zielhost wie `www` (bzw. A-Record auf dieselbe Server-IP).
+Kein Proxy-Only-Sonderfall nötig, Caddy holt das Cert selbst.
+
+### A2. Caddyfile auf dem Server
+`app.qrmaster.net` in den bestehenden Site-Block aufnehmen, damit Caddy automatisch ein
+Let's-Encrypt-Cert zieht:
+
+```caddyfile
+www.qrmaster.net, app.qrmaster.net {
+    reverse_proxy qrmaster-web:3000
+}
+```
+
+Danach `caddy reload`. Prüfen: `curl -sI https://app.qrmaster.net` muss 200 oder 301 liefern,
+kein TLS-Fehler.
+
+### A3. `.env` auf dem Server ergänzen
+Zwei Variablen statt einer. Die Trennung ist der Kern des ganzen Umbaus:
+
+Für **Deploy 1** reicht:
+
+```dotenv
+COOKIE_DOMAIN=.qrmaster.net
+```
+
+Für **Deploy 2** kommen dazu:
+
+```dotenv
+NEXT_PUBLIC_WWW_URL=https://www.qrmaster.net
+NEXT_PUBLIC_APP_URL=https://app.qrmaster.net
+```
+
+`NEXT_PUBLIC_APP_URL` erst zu Deploy 2 umstellen - vorher zeigt es auf www und muss dort
+bleiben. Fehlen die Werte, greifen die Produktions-Fallbacks in `src/lib/hosts.ts`; ein
+localhost-Wert kann damit nicht in gedruckte QR-Codes gelangen.
+
+`NEXTAUTH_URL` bleibt `https://www.qrmaster.net` (wird nur noch von
+`api/social-assets/route.ts` gelesen, kein Auth-Bezug mehr).
+
+### A4. Google Cloud Console
+Bei den OAuth-Credentials als **Authorized redirect URI** zusätzlich eintragen:
+
+```
+https://app.qrmaster.net/api/auth/google
+```
+
+Die alte www-URI **nicht löschen** – sie wird während der Übergangszeit noch von
+Sessions genutzt, die den Flow auf www gestartet haben.
+
+### A5. Nichts zu tun bei Stripe und TikTok
+- Stripe-Webhook zeigt auf `www.qrmaster.net/api/stripe/webhook` und bleibt gültig
+  (`/api/*` wird auf beiden Hosts weiter bedient, siehe B5).
+- TikTok `redirect_uri` bleibt auf `qrmaster.net` – verifizierte Domain, nicht anfassen.
+
+### A6. Deploy
+`npm run docker:prod` (Rebuild ist zwingend – `NEXT_PUBLIC_*` wird zur Build-Zeit ins
+Client-Bundle inlined, ein reiner Container-Restart genügt **nicht**).
+
+## Teil B — Meine Aufgaben (Code), in Diff-Reihenfolge
+
+### B1. Cookie-Domain teilen — muss zuerst live sein
+Ohne das ist auf `app.qrmaster.net` jeder ausgeloggt: das `userId`-Cookie ist heute host-only.
+
+- `src/lib/cookieConfig.ts:11` — `getAuthCookieOptions()`: `domain: process.env.COOKIE_DOMAIN` in Prod, in Dev `undefined` (localhost verträgt keine Punkt-Domain)
+- `src/lib/cookieConfig.ts:24` — `getCsrfCookieOptions()`: dito
+- `src/middleware.ts:34` — Attribution-Cookie: dito
+- `src/app/(main)/api/auth/logout/route.ts:7` — **kritisch**: löscht heute host-only. Nach der
+  Umstellung existieren bei Bestandsnutzern beide Varianten (alt host-only + neu domain-scoped).
+  Logout muss **beide** überschreiben, sonst bleibt ein Zombie-Cookie und der Nutzer ist nicht
+  wirklich ausgeloggt. Gilt für `userId`, `newsletter-admin` und das Attribution-Cookie.
+- `src/app/(main)/api/auth/google/route.ts:53,62` — OAuth-State + Post-Auth-Redirect-Cookie
+
+Kein Forced-Logout nötig: beide Cookie-Varianten tragen denselben signierten Wert, der Server
+akzeptiert jede. `verifySignedUserIdEdge` prüft die Signatur, das Teilen über eigene Subdomains
+ist unkritisch.
+
+**Dieser Schritt kann allein auf www deployt werden, bevor die Subdomain existiert** — nach außen
+unsichtbar, und wenn app.* dann live geht, funktionieren Sessions sofort.
+
+### B2. `NEXT_PUBLIC_APP_URL` entflechten
+Die Variable bedient heute App- **und** öffentliche URLs. Jede Fundstelle einzeln zuordnen:
+
+**Muss auf `WWW_URL` (öffentlich, teils in QR-Codes kodiert):**
+- `src/components/dashboard/QRCodeCard.tsx:82` — **höchstes Risiko im ganzen Umbau**: Basis für
+  die in den QR-Code kodierte `/r/<slug>`-URL. Bleibt das auf `APP_URL`, zeigen alle neu
+  heruntergeladenen und gedruckten Codes auf die Subdomain.
+- `src/app/(main)/r/[slug]/route.ts:50,61,84,89` — Landing-Basis vcard/text/coupon/feedback
+- `src/lib/email.ts:56,562`, `src/lib/marketingEmail.ts:30` — Mail-Links auf Marketing-Inhalte
+- `src/app/(main)/api/auth/signup/route.ts:20` — Verify-Mail-Link
+- `src/app/(main)/api/stripe/checkout/route.ts:64` — `cancel_url` → `/pricing`
+- `src/lib/metaConversions.ts:44`, `src/app/(main)/api/auth/signup/route.ts:150` — Event-Source-URLs
+
+**Bleibt/wird `APP_URL` (eingeloggt):**
+- `src/app/(main)/api/stripe/checkout/route.ts:63` — `success_url` → `/dashboard`
+- `src/app/(main)/api/stripe/create-checkout-session/route.ts:112,128` — `appUrl` + returnPath
+- `src/app/(main)/api/stripe/portal/route.ts:59` — `return_url` → `/settings`
+- `src/lib/email.ts:505` — hartcodiertes `https://www.qrmaster.net/dashboard` im Mail-Footer
+- `src/app/(main)/api/auth/google/route.ts:40,97` — `redirect_uri` (deckt A4 ab)
+
+### B3. Post-Auth-Sprung auf app.*
+Die einzige Cross-Host-Stelle. `sanitizeRedirectPath` (`src/lib/auth-flow.ts:4`) erlaubt bewusst
+nur relative Pfade — bleibt so, ich baue den Host separat davor:
+
+- `src/app/(main)/(auth)/login/ClientPage.tsx:56` und `login/LoginClient.tsx:65`
+- `src/app/(main)/(auth)/signup/ClientPage.tsx:70`
+- `src/app/(main)/api/auth/google/route.ts:224,228` — Server-Redirect
+- `src/app/(main)/api/auth/verify-email/route.ts:38` — setzt Cookie und redirected
+- `src/lib/auth-flow.ts:46` — `getPostOnboardingDestination`
+
+Muster: relativen Zielpfad wie heute bestimmen, dann `new URL(path, APP_URL)`. Weil das
+Auth-Cookie nach B1 auf `.qrmaster.net` gilt, ist der Nutzer nach dem Sprung sofort eingeloggt —
+kein Token-Handover über die URL nötig.
+
+### B4. Onboarding-Checkliste
+`src/components/dashboard/OnboardingChecklist.tsx:141` verlinkt `/onboarding` mit
+`redirect=/dashboard`. Beide Pfade liegen nach dem Umzug auf app.* → bleibt relativ, keine
+Änderung. Nur verifizieren.
+
+### B5. Middleware: Host-Routing
+`src/middleware.ts` — Kern des Umbaus. Der bestehende Apex-Redirect (Zeile 49) bleibt unberührt.
+Neu, direkt danach:
+
+- Host `app.qrmaster.net`:
+  - `/api/*`, `/_next/*`, statische Dateien: durchlassen (Stripe-Webhook, CSRF, alles)
+  - `protectedPaths` (Zeile 145) + `/upgrade` + `/onboarding`: bedienen wie heute
+  - alles andere: 301 auf `WWW_URL` + gleicher Pfad
+  - `/r/*`: 301 auf www — QR-Redirects gehören nicht auf die App-Subdomain
+- Host `www.qrmaster.net`:
+  - `protectedPaths` + `/upgrade` + `/onboarding`: 301 auf `APP_URL` + Pfad + Query
+    (damit alte Bookmarks und der Mail-Footer-Link weiter funktionieren)
+- Auth-Fail-Redirect (Zeile 166): zeigt auf `/signup` — das liegt auf www, also absolut
+  auf `WWW_URL` umstellen, `redirect`-Param bleibt relativ
+
+`/login` und `/signup` bleiben in `publicPaths` und werden nur auf www bedient.
+
+### B6. Indexierung der Subdomain dichtmachen
+`app.*` darf nicht in den Index, sonst Duplicate Content.
+
+- `src/middleware.ts`: auf Host `app.*` `X-Robots-Tag: noindex, nofollow` auf alle Responses
+- `public/robots-app.txt` neu anlegen (`User-agent: * / Disallow: /`), Middleware rewritet
+  `/robots.txt` auf app.* dorthin. `src/app/robots.ts` bleibt für www unverändert.
+- `/sitemap.xml` auf app.* → 301 auf www
+
+Gute Nachricht: `/dashboard`, `/create`, `/settings` sind in `src/app/robots.ts:7` bereits
+disallowed und nicht in der Sitemap → **kein Ranking-Verlust durch den Umzug.** Die Canonicals
+sind ohnehin hart auf www verdrahtet (`src/app/(main)/layout.tsx:13`).
+
+### B7. Docker-Env-Kette
+`NEXT_PUBLIC_*` wird zur Build-Zeit inlined **und** zur Laufzeit serverseitig gelesen. Beide
+Stellen müssen übereinstimmen, sonst gibt es Bugs, die nur im Client oder nur im Server auftreten:
+
+- `Dockerfile:34` — `NEXT_PUBLIC_APP_URL` auf `https://app.qrmaster.net`, neu
+  `ENV NEXT_PUBLIC_WWW_URL="https://www.qrmaster.net"`
+- `docker-compose.yml:58` — `NEXT_PUBLIC_WWW_URL` und `COOKIE_DOMAIN` ins `environment` des
+  `web`-Service durchreichen
+- `env.example` + `.env.example` — neue Variablen dokumentieren
+- `src/lib/env.ts` — optional, das Schema kennt `NEXT_PUBLIC_*` bisher gar nicht
+
+## Deploy-Choreografie
+
+Zwei Deploys, nicht einer. Das entkoppelt das Cookie-Risiko vom Routing-Risiko:
+
+1. **Deploy 1 (nur B1):** Cookie-Domain auf `.qrmaster.net`. Nur www ist live, nach außen
+   unsichtbar. 24 h beobachten: Login, Logout, Checkout müssen normal laufen.
+2. **A1 + A2 + A4:** DNS, Caddy, Google Console. `app.qrmaster.net` antwortet, serviert aber
+   noch dieselbe App wie www — unkritisch, weil noch nicht verlinkt und dank B6 noch nicht
+   indexierbar.
+3. **Deploy 2 (B2–B7):** Host-Routing scharf. Ab hier springt Login auf app.*.
+
+Rollback: Deploy 2 zurücknehmen. Weil das Cookie auf `.qrmaster.net` gilt, bleiben Sessions
+auch nach dem Rollback auf www gültig — niemand wird ausgeloggt. DNS/Caddy können stehen bleiben.
+
+## Testcheckliste (nach Deploy 2)
+
+Jeweils über beide Hosts:
+
+- [ ] `www.qrmaster.net/dashboard` → 301 auf `app.qrmaster.net/dashboard`, eingeloggt
+- [ ] `app.qrmaster.net/pricing` → 301 auf www
+- [ ] Signup auf www → Verify-Mail → Link führt eingeloggt auf app.*
+- [ ] Google-Login von www aus → landet eingeloggt auf app.*/dashboard bzw. /onboarding
+- [ ] Logout auf app.* → auf www **auch** ausgeloggt (prüft B1, häufigster Fehler)
+- [ ] Checkout: Upgrade auf app.* → Stripe → `success_url` app.*/dashboard, Abbruch → www/pricing
+- [ ] Stripe-Portal → zurück auf app.*/settings
+- [ ] Stripe-Webhook feuert weiter (Dashboard → Events, keine 4xx)
+- [ ] **QR-Code neu anlegen + herunterladen → kodierte URL ist `www.qrmaster.net/r/<slug>`**,
+      nicht app.* (prüft B2, das teuerste Fehlerbild)
+- [ ] Bestehender `/r/<slug>` redirected + trackt weiter, vcard/coupon/feedback-Landings laden
+- [ ] Mutation auf app.* (QR umbenennen) → CSRF greift, kein 403
+- [ ] `curl -sI https://app.qrmaster.net/dashboard | grep -i x-robots-tag` → noindex
+- [ ] `https://app.qrmaster.net/robots.txt` → `Disallow: /`
+- [ ] Search Console: `app.qrmaster.net` **nicht** als Property anlegen, keine Sitemap einreichen
+
+## Risiken
+
+| Risiko | Wo | Absicherung |
+|---|---|---|
+| Gedruckte QR-Codes zeigen auf app.* | `QRCodeCard.tsx:82` | B2, explizit im Test |
+| Logout wirkt nicht (Zombie-Cookie) | `logout/route.ts` | B1 löscht beide Varianten |
+| Client/Server-Env divergieren | `Dockerfile` vs. `docker-compose.yml` | B7, beide Stellen setzen |
+| Google-OAuth bricht | Cloud Console | A4, alte URI stehen lassen |
+| Duplicate Content auf app.* | — | B6 vor Deploy 2 |
+
+## Aufwand
+
+- Deine Seite: ~45 min (DNS, Caddy, .env, Google Console, Deploy)
+- Meine Seite: ~4–6 h Code über zwei Deploys
+- Keine DB-Änderung, kein Forced-Logout, kein SEO-Verlust

+# Plan: Testumgebung auf testmodul.qrmaster.net
+
+Stand: 2026-08-12 · Ziel: eine vollständige zweite Instanz auf `testmodul.qrmaster.net`, die
+einen anderen Branch (`test`) fährt, damit riskante Features - z.B. ein Bot, der bei
+Kundenerfolgen automatisch tweetet - vor dem Merge nach `master` real getestet werden können.
+
+**Status: nur Planung. Es wurde noch kein Code geändert.**
+
+## Architektur
+
+Zweiter, vollständig eigenständiger Compose-Stack aus demselben Repo, anderer Branch,
+eigene Datenbank, eigenes Redis. Caddy routet `testmodul.qrmaster.net` auf den Test-Container.
+
+```
+www.qrmaster.net   ─┐
+app.qrmaster.net   ─┴─> qrmaster-web       (Branch master, Prod-DB)
+testmodul.qrmaster.net ─> qrmaster-test-web (Branch test, eigene DB)
+```
+
+Prod und Test teilen sich **nichts** außer dem Docker-Netzwerk `qrmaster-network` (das ist
+`external: true`, darüber erreicht Caddy beide Container per Namen).
+
+## Ausgangslage im Repo
+
+Im Working Tree liegen uncommittete Änderungen, die nicht aus der Subdomain-Arbeit stammen:
+
+- `src/lib/cookieConfig.ts` - `getAuthCookieName()` ist angelegt (liest `AUTH_COOKIE_NAME`,
+  Default `userId`)
+- `src/lib/session.ts` - importiert `getAuthCookieName`, **benutzt es aber nicht**; Zeile 14
+  hat weiterhin `export const AUTH_COOKIE_NAME = 'userId'`
+
+Damit ist die Funktion aktuell wirkungslos. Die Verkabelung fehlt an 6 Stellen (siehe unten).
+Vor dem Weiterbauen klären, ob diese Änderungen bewusst so stehen oder committed werden sollen.
+
+Ein Branch `test` existiert noch nicht. Vorhanden: `analytics`, `dynamisch`,
+`feature/mockup-landing-page`, `icons`, `master`.
+
+## Falle 1 - Cookie-Kollision (blockierend)
+
+Produktion setzt das Session-Cookie `userId` auf `.qrmaster.net`. Der Browser schickt es damit
+**auch an `testmodul.qrmaster.net`**. Setzt Test sein eigenes `userId` als Host-Cookie, liegen
+zwei gleichnamige Cookies vor, und `req.cookies.get('userId')` in
+[middleware.ts:250](src/middleware.ts:250) liefert undefiniert welches davon. Folge: Login auf
+Test verhält sich sporadisch wie ausgeloggt - ein Fehlerbild, das schwer zu greifen ist, weil es
+vom Cookie-Zustand des jeweiligen Browsers abhängt.
+
+**Lösung:** Cookie-Name pro Umgebung konfigurierbar. `getAuthCookieName()` fertig verkabeln,
+Test setzt `AUTH_COOKIE_NAME=userId_test`.
+
+Zu ändernde Stellen:
+
+| Datei | Was |
+|---|---|
+| `src/lib/session.ts:14` | `AUTH_COOKIE_NAME`-Konstante durch `getAuthCookieName()` ersetzen (Zeilen 71, 78 ziehen nach) |
+| `src/middleware.ts:250` | `req.cookies.get('userId')` → `getAuthCookieName()` |
+| `src/app/(main)/api/auth/google/route.ts:227` | `cookies.set('userId', …)` |
+| `src/app/(main)/api/auth/verify-email/route.ts:40` | `cookies.set('userId', …)` |
+| `src/app/(main)/api/auth/logout/route.ts:12` | Eintrag in `appendExpiredCookies` |
+| `src/app/(main)/api/user/delete/route.ts:77` | `cookies().delete('userId')` |
+
+Wie `COOKIE_DOMAIN` muss `AUTH_COOKIE_NAME` **auch zur Build-Zeit** gesetzt sein - `process.env`
+wird ins Edge-Middleware-Bundle inlined. Also `ARG` + `ENV` im Dockerfile und als Build-Arg im
+Compose-Override, analog zu `COOKIE_DOMAIN`.
+
+Achtung beim Umstellen der Produktion: ändert sich dort der Cookie-Name, werden **alle
+bestehenden Sessions ungültig** (alle Nutzer ausgeloggt). Deshalb Prod beim Default `userId`
+lassen und nur Test abweichen - dann passiert genau nichts.
+
+## Falle 2 - Host-Routing würde nach Prod umleiten
+
+Die Middleware kennt nur zwei Hosts. Auf `testmodul.qrmaster.net` greift der Zweig
+`else if (isAppPath(path))` und schickt `/dashboard` per 301 auf **app.qrmaster.net**, also in
+die Produktion.
+
+**Lösung ohne Codeänderung:** Test zeigt beide Origins auf sich selbst. Dann ist
+`isHostSplitEnabled()` false, `getAppHostname()` liefert null, und das komplette Host-Routing
+schaltet sich ab. Test läuft als Ein-Host-Umgebung mit Marketing *und* App unter einer Domain -
+genau wie die lokale Entwicklung.
+
+Das ist der Grund, warum beide Variablen in `.env.test` identisch sein müssen. Wer dort später
+aus Versehen `NEXT_PUBLIC_APP_URL=https://app.qrmaster.net` einträgt, schickt seine Testklicks
+in die Produktion.
+
+## Falle 3 - ausgehende Nebenwirkungen
+
+Das ist beim Twitter-Bot der eigentliche Punkt. Eine Testumgebung, die auf echte Dienste zeigt,
+ist keine Testumgebung.
+
+| Dienst | Auf Test |
+|---|---|
+| Twitter/X | eigener App-Key auf einen Test-Account, **oder** ein `DRY_RUN`-Flag, das den Tweet nur loggt |
+| Stripe | Test-Keys (`sk_test_…`), eigener Webhook-Endpoint auf testmodul |
+| Resend / SMTP | Test-Key oder komplett deaktivieren - sonst mailt Test an echte Kunden |
+| Meta Conversions / PostHog / Umami | leer lassen, sonst verschmutzt Test die Prod-Analytics |
+| Cron (Retention-Mails) | auf Test abschalten |
+
+Empfehlung für den Bot: das `DRY_RUN`-Flag von Anfang an einbauen, nicht erst wenn es einmal
+schiefging. Ein Bot, der Kundenerfolge tweetet, ist genau die Sorte Feature, die man nicht
+"kurz mal live" testen will.
+
+## .env.test
+
+```dotenv
+NODE_ENV=production
+
+# Ein-Host-Betrieb: schaltet das Host-Routing ab
+NEXT_PUBLIC_WWW_URL=https://testmodul.qrmaster.net
+NEXT_PUBLIC_APP_URL=https://testmodul.qrmaster.net
+NEXTAUTH_URL=https://testmodul.qrmaster.net
+
+# Host-Cookie, nicht .qrmaster.net - sonst leckt die Test-Session nach Prod
+COOKIE_DOMAIN=
+AUTH_COOKIE_NAME=userId_test
+
+# Anderes Secret: ein Leak auf Test kann dann keine Prod-Session fälschen
+NEXTAUTH_SECRET=<eigenes Secret>
+IP_SALT=<eigenes Salt>
+
+# Nicht indexieren
+NEXT_PUBLIC_INDEXABLE=false
+
+# Eigene DB im Test-Stack
+POSTGRES_USER=postgres
+POSTGRES_PASSWORD=<eigenes, hex - ein "/" aus base64 zerlegt die DATABASE_URL>
+POSTGRES_DB=qrmaster_test
+# DATABASE_URL nicht setzen - Compose baut sie aus den drei Werten oben
+
+# Test-Keys / leer, siehe Falle 3
+STRIPE_SECRET_KEY=sk_test_…
+RESEND_API_KEY=
+```
+
+`NEXTAUTH_URL` darf hier auf testmodul zeigen - der einzige echte Leser ist die
+Social-Assets-Route, und die soll auf Test ohnehin nicht gegen die verifizierte TikTok-Domain
+laufen.
+
+## Infra
+
+**`docker-compose.test.yml`** als Override, das nur die Abweichungen setzt:
+
+- `container_name`: `qrmaster-test-db`, `qrmaster-test-redis`, `qrmaster-test-web` - die Namen
+  sind im Basis-File fest vergeben und würden sonst kollidieren
+- Host-Ports entfernen - `5435` (db) und `8080` (adminer) sind schon von Prod belegt
+- `entrypoint: ["node", "server.js"]` für `web`, siehe Migrationen oben
+- Build-Args für `COOKIE_DOMAIN`, `AUTH_COOKIE_NAME`, `NEXT_PUBLIC_*`
+
+### Netzwerk-Isolation (kritisch)
+
+`db` und `redis` hängen im Basis-File am Netzwerk `qrmaster-network`
+([docker-compose.yml:22](docker-compose.yml:22)), und das ist `external: true`, also für beide
+Stacks dasselbe. Compose vergibt jedem Service automatisch einen Netzwerk-Alias mit seinem
+Servicenamen - zwei Stacks mit einem Service `db` am selben Netzwerk heißt: **`db` löst auf
+zwei Container auf und Dockers DNS wählt zufällig.** Der Test-Container könnte damit auf der
+Produktionsdatenbank landen, nicht deterministisch, sondern mal so und mal so.
+
+Deshalb bekommt der Test-Stack ein eigenes internes Netzwerk. Nur `web` hängt zusätzlich am
+geteilten Netz, damit Caddy es erreicht:
+
+```yaml
+services:
+  db:
+    container_name: qrmaster-test-db
+    ports: !reset []
+    networks: [test-internal]
+  redis:
+    container_name: qrmaster-test-redis
+    networks: [test-internal]
+  web:
+    container_name: qrmaster-test-web
+    entrypoint: ["node", "server.js"]
+    networks: [test-internal, qrmaster-network]
+
+networks:
+  test-internal:
+    driver: bridge
+```
+
+`POSTGRES_DB` heißt auf Test `qrmaster_test`. Die Trennung kommt zwar schon vom eigenen
+Container und Volume, aber der abweichende Name macht bei einer von Hand getippten
+`psql`-Sitzung sofort sichtbar, auf welcher Instanz man ist - die billigste Versicherung
+gegen ein `DELETE` in der falschen Datenbank.
+
+Dafür muss der Healthcheck mitgezogen werden: das Basis-File hat `pg_isready -d qrmaster`
+hartkodiert ([Zeile 19](docker-compose.yml:19)). Ohne Override prüft er eine Datenbank, die
+es nicht gibt, der Container bleibt `unhealthy`, und `web` startet wegen
+`depends_on: condition: service_healthy` nie.
+
+Start:
+
+```bash
+docker compose -p qrmaster-test --env-file .env.test \
+  -f docker-compose.yml -f docker-compose.test.yml up -d --build
+```
+
+Der Projektname `-p qrmaster-test` gibt automatisch eigene Volumes - die Test-DB kann die
+Prod-DB also nicht anfassen.
+
+**Caddy:**
+
+```caddyfile
+testmodul.qrmaster.net {
+    reverse_proxy qrmaster-test-web:3000
+}
+```
+
+**`robots.ts`** an `NEXT_PUBLIC_INDEXABLE` koppeln. Aktuell liefert es hart `Allow` plus
+www-Sitemap; auf Test soll `Disallow: /` stehen. `NEXT_PUBLIC_INDEXABLE=false` setzt heute nur
+das Meta-Tag in den beiden Layouts, nicht die robots.txt.
+
+## Branch-Workflow
+
+```bash
+git checkout -b test master
+git push -u origin test
+```
+
+Deploy auf Test: auf dem Server `git checkout test && git pull`, dann der Compose-Befehl oben.
+Rebuild ist immer nötig, weil `NEXT_PUBLIC_*` und `AUTH_COOKIE_NAME` zur Build-Zeit inlined
+werden.
+
+Ablauf für ein Feature: Branch von `test` abzweigen → auf Test deployen und prüfen → nach
+`master` mergen → Prod-Deploy. `test` bleibt dauerhaft bestehen und wird regelmäßig von
+`master` nachgezogen, damit er nicht wegdriftet.
+
+## Datenbank - entschieden: leeres Schema
+
+Eigene PostgreSQL-Instanz im Test-Stack, befüllt mit **Struktur ohne Zeilen**. Keine
+Kundendaten verlassen die Produktion.
+

+# Struktur aus Prod ziehen (keine Zeilen)
+docker exec qrmaster-db pg_dump -U postgres --schema-only qrmaster > schema.sql
+
+# in die Test-DB einspielen
+docker exec -i qrmaster-test-db psql -U postgres -d qrmaster_test < schema.sql
+```
+
+Danach einen Testaccount anlegen - entweder über das Signup-Formular auf testmodul oder per
+`INSERT`.
+
+**Warum der Dump aus Prod und nicht aus Prisma:** `prisma/migrations` steht auf April 2026.
+Alles seitdem (Pulse-Spalten, `BARCODE`-Enum-Wert, ...) kam per Hand-SQL. Die Produktions-DB
+ist damit die einzige Stelle, die die aktuelle Struktur kennt.
+
+**Warum leer statt Kopie:** beim Tweet-Bot willst du wissen, welcher Testfall den Tweet
+ausgelöst hat. Mit Prod-Daten könnte es auch irgendein echter Kunde von vor Monaten gewesen sein.
+
+### Keine Migrationen - der Entrypoint muss überschrieben werden
+
+[docker/entrypoint.sh:5](docker/entrypoint.sh:5) führt bei **jedem** Container-Start
+`npx prisma migrate deploy` aus. Das widerspricht der Policy aus CLAUDE.md (Schema-Änderungen
+nur per Hand-SQL) und würde auf einer frischen Test-DB die 6 veralteten Migrationen anwenden -
+also ein Schema vom Stand April 2026 bauen, dem alle späteren SQL-Änderungen fehlen. Die App
+liefe dann in "column does not exist".
+
+Im Test-Override deshalb:
+
+```yaml
+web:
+  entrypoint: ["node", "server.js"]
+```
+
+Prod bleibt unverändert. Der Schema-Dump bringt die Tabelle `_prisma_migrations` ohnehin mit,
+inklusive der 6 als angewandt markierten Einträge - der Zustand ist also identisch zu Prod.
+
+**Separat zu klären (nicht Teil dieses Plans):** ob `prisma migrate deploy` langfristig auch
+aus dem Prod-Entrypoint verschwinden soll. Heute ist es dort ein No-Op, aber es ist eine
+scharfe Waffe, die bei einem versehentlich hinzugefügten Migrationsfile auf die Produktion
+losgeht.
+
+### Spätere Schema-Änderungen
+
+Ein SQL-Statement, das auf Test getestet wurde, wird auf Prod **erneut von Hand** ausgeführt -
+es gibt keinen automatischen Weg von Test nach Prod. Die Dateien in `sql/` sind der Ort dafür.

+
+- [ ] `testmodul.qrmaster.net` lädt, gültiges Zertifikat
+- [ ] `testmodul.qrmaster.net/dashboard` bleibt **auf testmodul** und springt nicht nach app.qrmaster.net
+- [ ] Login auf Test funktioniert, während man in Prod eingeloggt ist - beide Sessions unabhängig
+- [ ] Logout auf Test loggt **nicht** aus Prod aus (und umgekehrt)
+- [ ] Im Browser liegen zwei Cookies: `userId` (Domain `.qrmaster.net`) und `userId_test` (Host `testmodul.qrmaster.net`)
+- [ ] `curl -sI https://testmodul.qrmaster.net` → kein `X-Robots-Tag` nötig, aber `/robots.txt` liefert `Disallow: /`
+- [ ] Test-DB enthält **keine** echten Kunden: `SELECT count(*) FROM "User";` muss die Zahl der selbst angelegten Testaccounts sein
+- [ ] `docker compose -p qrmaster-test exec web env | grep DATABASE_URL` zeigt auf den Test-Container, und `SELECT count(*)` dort weicht von Prod ab - beweist, dass der `db`-Alias nicht auf Prod zeigt
+- [ ] Container-Logs beim Start enthalten **kein** "Applying Prisma migrations"
+- [ ] Ein Testlauf des Bots postet nichts auf dem echten Account

+# Social milestone worker
+
+The app detects QR-code scan milestones and stores customer consent. It does not
+hold X or Meta credentials. The external worker publishes what was approved —
+per channel, never more.
+
+## Consent is bound to a channel
+
+Approving a post on X says nothing about Instagram: different audience,
+different disclosure about the customer's business. Every channel therefore has
+its own checkbox in the dialog, its own text, its own handle and its own row in
+`SocialMilestonePost`. **No row means no consent.** A channel is only offered
+where a publisher is configured — `SOCIAL_MILESTONE_CHANNELS` (app) must stay in
+sync with `SOCIAL_WORKER_CHANNELS` (worker), otherwise approvals pile up in the
+queue with nobody to publish them.
+
+## Test setup (manual SQL only)
+
+1. Apply, in this order, to `qrmaster_test`:
+   [`sql/2026-08-13_social_milestones.sql`](../../sql/2026-08-13_social_milestones.sql),
+   [`sql/2026-08-16_social_milestone_retries.sql`](../../sql/2026-08-16_social_milestone_retries.sql),
+   [`sql/2026-08-16_social_milestone_channels.sql`](../../sql/2026-08-16_social_milestone_channels.sql).
+2. Set distinct `CRON_SECRET` and `INTERNAL_API_SECRET` values in `.env.test`.
+   For an end-to-end test without 1,000 scans, also set
+   `SOCIAL_MILESTONE_THRESHOLDS=1` (or `1,2`). Do not set this on production.
+   Publishing is immediate after consent by default. Set
+   `SOCIAL_MILESTONE_POST_DELAY_HOURS=24` only if a revocation window is desired.
+   Set `SOCIAL_MILESTONE_MIN_GAP_HOURS=0` on test, otherwise the second
+   milestone waits a full day behind the first one.
+3. Deploy using the documented test compose command. `CRON_SECRET` is forwarded
+   to the web service by `docker-compose.yml`.
+4. Trigger detection manually:
+
+```bash
+curl -H "Authorization: Bearer $CRON_SECRET" \
+  https://testmodul.qrmaster.net/api/cron/social-milestones
+```
+
+The detector creates records at 1,000 and 10,000 unique scans only. It is safe
+to call repeatedly because `(qrId, kind)` is unique. A QR code that is already
+past several thresholds on first detection only produces the highest one.
+
+## Queue contract
+
+```bash
+curl -H "Authorization: Bearer $INTERNAL_API_SECRET" \
+  "https://qrmaster.net/api/internal/social-milestones?channel=instagram"
+```
+
+Returns at most one approved post for that channel, claims it, and expects a
+result report for the returned `id`:
+
+```bash
+curl -X PATCH -H "Authorization: Bearer $INTERNAL_API_SECRET" \
+  -H "Content-Type: application/json" \
+  -d '{"id":"<post-id>","result":"posted","postUrl":"https://..."}' \
+  https://qrmaster.net/api/internal/social-milestones
+```
+
+First attempts are spaced by `SOCIAL_MILESTONE_MIN_GAP_HOURS` (default 24) per
+channel, so the brand timeline cannot be flooded when several customers consent
+on the same day. A blocked poll answers
+`{"milestone": null, "reason": "spacing", "nextPostAt": "..."}`.
+
+`milestone.text` is published **verbatim** — it is the text the customer read
+before consenting. The image is not part of the payload: the worker downloads it
+from `<QRMASTER_API_BASE>/s/m/<shareToken>/og`, the same renderer that serves the
+popup and the link preview. `?format=` takes `landscape` (1200×630, default),
+`square` (1080×1080) or `portrait` (1080×1350).
+
+## Instagram
+
+Publishing runs against the QRMaster.net Business account (see
+[social-accounts-and-jobs.md](social-accounts-and-jobs.md)) in three steps:
+`POST /{ig-user-id}/media` → poll `status_code` until `FINISHED` →
+`POST /{ig-user-id}/media_publish`.
+
+Worth knowing before enabling it:
+
+- **JPEG only.** The worker flattens the rendered PNG onto white and uploads it
+  through `POST /api/social-assets`; Meta downloads `image_url` itself, so it has
+  to be publicly readable on the verified domain. `SOCIAL_ASSET_ADMIN_KEY` is the
+  existing `TIKTOK_ADMIN_KEY`.
+- **No clickable links in captions.** The Instagram text therefore ends in
+  hashtags instead of the share URL, and mentions use the customer's Instagram
+  handle, not their X handle.
+- **50 posts / 24 h**, verifiable via `GET /{ig-user-id}/content_publishing_limit`.
+- **Reconciliation is caption-based.** Before a repeated attempt the worker
+  compares the caption against the last 25 media items. Two milestones with an
+  identical caption — same QR title, same scan count — would be treated as the
+  same post; the 24 h spacing makes that combination unlikely but not impossible.
+- Required environment: `SOCIAL_WORKER_CHANNELS=x,instagram`, `INSTAGRAM_USER_ID`,
+  `INSTAGRAM_ACCESS_TOKEN`, plus `SOCIAL_MILESTONE_CHANNELS=x,instagram` on the
+  web service so the dialog asks for it in the first place.
+
+Do not configure this worker against `testmodul`. LinkedIn has no approved
+brand-posting integration in this project. Customers can self-share on all three:
+X opens a prefilled intent, LinkedIn gets the text copied, Instagram opens the
+system share sheet on a phone and falls back to an image download.
+
+## Failed posts
+
+A reported failure — and a claim the worker never confirmed — counts as one
+attempt. The queue re-schedules the post itself after 5, then 10 minutes and only
+parks it in `failed` once three attempts are used up. Before posting again the
+worker reconciles against the account (share token on X, caption on Instagram),
+so a failure reported after a successful post cannot duplicate it.
+
+The consent dialog opens once per milestone, so a customer who has closed it can
+no longer see or restart a failed post from there. Settings → Milestone sharing
+lists every milestone with one line per channel and offers "Try again" (re-queues
+the approved text unchanged) and "Cancel" (revokes that channel before anything
+is published).
