Linear board ingest reuses the GitHub board lane’s Ingester, BoardWebhookArm and BoardReconciler (Pulls nil) over one shared Linear client: a Linear updated-order list call feeds the reconciler and Linear Issue webhooks feed the arm, both writing through IssueProjection.PublishIssueUpdate; Linear team keys are forge_repo_subscriptions rows under (4, linear.app) seeded by –forge-linear-teams, and the issues table holds a projection of the subscribed teams’ issues, scoped by the cold-start and drift policy in OQ-2 and OQ-5
