bug: karen crashes when slack integration missing

Start in flexus_simple_bots/karen/karen_bot.py at karen_main_loop around line 396, then read the optional integration setup/loading flow. Reproduce startup with Slack absent and verify the bot no longer repeatedly restarts with KeyError 'slack' and can complete normal startup behavior.

KeyError: 'slack'

Error Summary

Karen pod in isolated repeatedly logs KeyError: 'slack' on startup. The pod is running but the bot main loop repeatedly restarts internally and never completes normal startup behavior. This is a persistent service-breaking failure whenever the slack integration is absent.

Stacktrace

File "/app/flexus_client_kit/ckit_bot_exec.py", line 308, in crash_boom_bang
File "/app/flexus_simple_bots/karen/karen_bot.py", line 396, in karen_main_loop

Root Cause

• File: flexus_simple_bots/karen/karen_bot.py:396
• Function: karen_main_loop
• Why: The setup/loading flow allows optional integrations, but the main loop unconditionally indexes integrations["slack"], so a missing Slack connection causes an unhandled KeyError.
• Git blame: @Humberto Yusta in 4be28233 (2026-04-01)

Code Snippet

pdoc_integration: fi_pdoc.IntegrationPdoc = integrations["flexus_policy_document"]
email_respond_to = set(a.strip().lower() for a in setup.get("EMAIL_RESPOND_TO", "").split(",") if a.strip())
shopify = fi_shopify.IntegrationShopify(fclient, rcx)
sched = fi_sched.IntegrationSched(rcx)
slack: fi_slack.IntegrationSlack = integrations["slack"]
telegram: fi_telegram.IntegrationTelegram = integrations["telegram"]
