"""Drop legacy Slack tables — Slack now runs on the unified channel stack
|
|
|
|
Revision ID: drop_slack_tables_001
|
|
Revises: add_channel_tables_001
|
|
Create Date: 2026-07-10 22:00:00.000000
|
|
|
|
The old integration (slack_tokens with plaintext tokens, per-thread
|
|
slack_conversations, per-channel agent_slack_configs, workspace storage modes)
|
|
is replaced by channel_accounts / channel_conversations / agent_channel_configs.
|
|
The old integration had no production users, so no data is migrated. Downgrade
|
|
recreates empty tables via the original add_slack_integration_001 shapes.
