Multi-Bot Streaming Test
========================

Two agents on the same Slack workspace, mounted on different prefixes.
Both use streaming mode. Tests session isolation: each bot gets its own
DB session even when responding in the same thread.

Setup:
  1. Two Slack apps (Ace + Dash) installed to the same workspace
  2. Event Subscription URLs:
       Ace  -> https://<tunnel>/ace/events
       Dash -> https://<tunnel>/slack/events
  3. Environment variables:
       ACE_SLACK_TOKEN,  ACE_SLACK_SIGNING_SECRET
       DASH_SLACK_TOKEN, DASH_SLACK_SIGNING_SECRET
  4. ngrok: ngrok http --domain=<your-subdomain>.ngrok-free.dev 7777

Slack scopes (per app): app_mentions:read, assistant:write, chat:write, im:history
