+### Evening Session (D J back from work)
+- **KIPP UI v2 chat confirmed working** — D J tested on Mac, chat end-to-end functional at 18:34
+- **Voice input added** — mic button in chat overlay triggers browser Speech Recognition, auto-sends on final transcript
+- **Piper TTS installed** on KIPP VM — `pip3 install piper-tts`, Amy medium voice model downloaded
+- **TTS API server** built (port 8081, systemd kipp-tts.service) + proxy through UI server on port 8080
+- **Piper voice quality confirmed** — sent D J audio sample via Telegram, not robotic
+- **Caddy WebSocket issue** — persistent 503 on WSS through Caddy reverse proxy
+  - Direct WS to 192.168.86.100:18789 works perfectly every time
+  - Caddy returns 503 on WebSocket upgrade specifically
+  - Fixed gateway: added `192.168.86.0/24` to trustedProxies, added `http://192.168.86.100:8080` to allowedOrigins
+  - Gateway logs showed "origin not allowed" and "proxy headers from untrusted address"
+  - Even after gateway fix, Caddy still 503s — Caddy itself is the bottleneck
+  - Need to check Caddy logs on whatever machine it runs on (192.168.86.1?)
+  - D J's Caddyfile is clean: just `reverse_proxy 192.168.86.100:18789`
+  - Chat works intermittently — connects sometimes then drops
+- **Caddy config** (D J's full Caddyfile): media→86.50:8096, vault→86.244:7080, git→86.244:3002, share→86.26:3000, kippui→86.100:8080, kipp→86.100:18789
+- **@Argona0x tweet analyzed** — $50→$2,980 Polymarket bot claim, 90% likely fake (engagement farming)
+- **Kelly Criterion explained** to D J
