+"""Add blocker_raised_by to tasks.
+
+Revision ID: 005_blocker_raised_by
+Revises: 004_provider_routing
+Create Date: 2026-04-22
+
+Adds `tasks.blocker_raised_by` so `roboco_task_unblock` can restore the
+task to the agent who actually raised the block/escalation. Without this,
+escalations (which reassign the task to the escalation target for
+resolution) leave the dev's identity lost — unblocking just flips status
+back to `in_progress` with the PM still on the hook, so the orchestrator
+never respawns the original dev and the task stalls.
+
+NULL = never blocked, or legacy rows pre-migration. `unblock` treats NULL
+as "no-op on assignee" to preserve back-compat.
