Kyle Carberry	34d9392e37	chore(db): remove workspace_agent_id from chats table (#22442) ... ## Summary Remove the `workspace_agent_id` column from the `chats` table and dynamically look up the first workspace agent instead. ## Problem When a workspace is stopped and restarted, the workspace agent gets a new ID. The `workspace_agent_id` stored on the chat at creation time becomes stale, making the agent unreachable. This caused chats to break after workspace restarts. ## Solution Instead of persisting the agent ID, dynamically look up the first agent from the workspace's latest build via `GetWorkspaceAgentsInLatestBuildByWorkspaceID` whenever an agent connection is needed. The `workspace_id` on the chat remains stable across restarts. This behavior may be refined later (e.g., agent selection heuristics), but picking the first agent resolves the immediate breakage. ## Changes - **Migration 000425**: Drop `workspace_agent_id` column from `chats` - **SQL queries**: Remove `workspace_agent_id` from `InsertChat` and `UpdateChatWorkspace` - **chatd.go**: `getWorkspaceConn` and `resolveInstructions` now look up agents dynamically from workspace ID - **chatd.go**: Remove `refreshChatWorkspaceSnapshot` (no longer needed) - **createworkspace.go**: Stop persisting agent ID when associating workspace with chat - **subagent.go**: Stop passing agent ID to child chats - **SDK/frontend**: Remove `WorkspaceAgentID` / `workspace_agent_id` from Chat type --------- Co-authored-by: Kyle Carberry <kylecarbs@gmail.com>	2026-02-28 16:46:51 -05:00
