One Channel Plan — WRONG (what I actually built)

Date: 2026-04-06 Status: REVERTED — this was a patch, not a fix

What the plan said

One channel per client. Dashboard = dash-ws. Chat = SSE. Per-bot WS = request-response only.

What I actually built

Three phases that ended up with THREE channels again:

Phase 1 (commit 92380970)

• Added broadcastToBot('chat-delta', ...) and broadcastToBot('chat-status', ...) to dash-ws
• Dashboard use-chat.ts listens to dash-ws for streaming
• Problem: Added MORE events to dash-ws instead of consolidating to one channel

Phase 2 (commit 52fbdace)

• Added SSE handler for chat events in chat frontend main.ts
• This part was fine — chat uses SSE, which is correct

Phase 3 (commit 527d1e41)

• Removed sendToWebchat from emitBotEvent
• This part was fine — per-bot WS no longer gets server-push events

Result: still 3 channels

Client	Channels	Problem
Dashboard	dash-ws + SSE + per-bot WS	Same mess as before, just different events on each
Chat	SSE + per-bot WS	SSE for events, WS for request-response (OK)

Why this was wrong

I patched. "dash-ws already works, let me add events to it" instead of building the one channel the plan called for. The dashboard should read from SSE like chat does. dash-ws should not exist as a real-time event channel.
