let profile vor try-block hoisten, damit es im plan-routing-Fallback (line 210, profile?.plan) sichtbar ist. Vorher: const profile innerhalb try-block → block-scoped → ReferenceError außerhalb. Demographics-Block-Injection added — gracefully no-op wenn neue Felder (birthYear/gender/etc.) noch nicht im DB-Schema sind (optional chaining).

/**
|
||
* GET /api/coach/sos-stream?session=xyz — Streaming SOS Coach (Claude Sonnet 4.5)
|
||
*
|
||
* Streamt Sonnets Antwort als SSE (Server-Sent Events).
|
||
* Frontend nutzt react-native-sse (EventSource) für progressives Streaming.
|
||
*
|
||
* Format (SSE-Standard):
|
||
* event: message
|
||
* data: <text chunk>
|
||
*
|
||
* event: chips
|
||
* data: [{"label":"...","action":"..."}]
|
||
*
|
||
* Flow:
|
||
* 1. Client POSTet zu /api/coach/sos-session → { sessionId }
|
||
* 2. Client öffnet GET /api/coach/sos-stream?session=xyz via EventSource
|
||
* 3. Backend lädt Session-Daten (messages/locale) aus In-Memory Store
|
||
* 4. Streamt Antwort als SSE-Events
|
||
*
|
||
* Fallback: bei Sonnet-Fehler wirft 503; Frontend kann auf /coach/message zurückfallen.

|

- Antworte als REINER TEXT, KEINE JSON-Wrapper, KEIN Markdown, KEINE Aufzählungen.
|
||
- Sei warm, präsent, menschlich — wie eine echte Freundin am Telefon.
|
||
- KURZ: 1-2 Sätze, max 3 nur in seltenen Ausnahmen. Ruhiger Rhythmus mit kurzen Pausen.

- Validiere zuerst das Gefühl, dann sanfte Frage ODER Vorschlag.

ABSOLUT KRITISCH — NIEMALS die Chip-Optionen im Prosa-Text auflisten oder paraphrasieren.
|

Der Prosa-Text wird dem User VORGELESEN (TTS) — Chip-Aufzählung klingt unnatürlich
|
||
("warum sprichst du eine Liste?"). Die Chips erscheinen visuell als Buttons.
|
||
|
||
✗ FALSCH: "Magst du atmen oder lieber spielen?" (= Aufzählung)
|
||
✗ FALSCH: "Du kannst eine Atemübung oder ein Spiel machen."
|
||
✗ FALSCH: "Hier sind ein paar Optionen: Atmen, Spielen oder Reden."
|
||
✗ FALSCH: "Magst du mit mir reden, eine Atemübung machen oder ein Spiel?"
