 ## Wie Fehler hierher kommen
 - Jeder `swift build` / `swift build -c release` / Skript-Lauf mit Fehler → Log-Ausschnitt + Exit-Code hier eintragen.
 - Gitea-Push/Release-Fehler (z. B. 401, Repo existiert schon, Asset-Upload schlägt fehl) ebenfalls hier dokumentieren.
+- Neue Tests: `AnsiParser` per `swiftc`-Harness (`/tmp`, SGR/CRLF/Clear/Map), `PTYSession` per Smoke-Test (`/bin/echo` + `ssh -G` durchs echte PTY).
+
+## #6 — SSH-Klick öffnet kein Terminal (User-Bugreport)
+**Phase:** Laufzeit, SSH-Profil → Verbinden
+**Ursache:** `Services/ConnectionServices.swift` nutzte `NSAppleScript(tell application "Terminal" to do script …)`. Ohne `NSAppleEventsUsageDescription` und ohne Error-Auswertung scheitert das still — es passiert schlicht nichts.
+**Fix:**
+- Neu: `Services/PTYSession.swift` — echte PTY-Session (`posix_openpt`, `ssh` mit TTY), `TerminalManager` pro Profil (überlebt Tab-Wechsel).
+- Neu: `Views/EmbeddedTerminalView.swift` — In-App-Terminal im Dracula-Theme (`Services/TerminalTheme.swift`, `Services/AnsiParser.swift`), Auto-Connect per `onAppear`, Eingabezeile + Passwort-Modus + `^C`/`^D`.
+- `SessionView` bettet das Terminal ein (min. 380 pt), `ContentView.connect()` öffnet nur noch den Tab.
+- Extern-Fallback umgebaut auf `.command`-Datei via `NSWorkspace` (keine Automation-Rechte nötig).
+**Verifikation:** `swift build` ok; Parser-Harness 8/8; PTY-Smoke (`/bin/echo` → Output + Exit 0); `ssh -G example.com` durchs PTY ok.
+**Status:** ✅ behoben.
+
+## #7 — ANSI-Parser: Text bekam falschen Stil
+**Phase:** `swiftc`-Harness während #6
+**Log:** `text("rot", fg: nil)` statt `fg: 1`
+**Ursache:** Chunk wurde erst nach dem SGR-Wechsel geflusht.
+**Fix:** `Services/AnsiParser.swift` — `flush()` vor `parseCSI`.
+**Verifikation:** Harness 8/8 grün.
+**Status:** ✅ behoben.
 
 ## #4 — Gitea-Upload: 401 trotz erreichbarem Server
 **Phase:** `POST /api/v1/user/repos` + `GET /api/v1/user` auf `https://git.sysdaemon.xyz` (Version 1.27.3, per `/api/v1/version` bestätigt)

 ## Verbinden
 - Profil wählen → `▶ Verbinden` oder Doppelklick.
-- SSH/SFTP: öffnet Terminal.app mit `ssh -p PORT -i KEY user@host`. Befehl steht zusätzlich kopierbar in der Detailansicht.
+- SSH/SFTP: **In-App-Terminal (Dracula-Theme) direkt im Tab** — verbindet automatisch, kein externes Fenster nötig. Eingabezeile unten (Auge-Icon = Passwort-Modus), `^C`/`^D`-Buttons, `Leeren`, `Trennen`/`Verbinden`, `Tab schließen`.
+- Alternativ: `In Terminal.app öffnen` (öffnet eine `.command`-Datei, braucht keine Automation-Berechtigung) oder `Befehl kopieren`.
 - RDP: startet `xfreerdp` (falls vorhanden) oder öffnet MS Remote Desktop.
 - VNC: öffnet `vnc://host:port`.
