Author and run Linear bug workflows via the GraphQL API: issue creation, state transitions (workflowState assignment), priority assignment (0 No priority / 1 Urgent / 2 High / 3 Medium / 4 Low), label-based classification, search by team and content. Covers the issueCreate mutation, issueUpdate for state transitions, the workflowStates query for per-team state IDs, and Linear's API-key vs OAuth Bearer auth modes; resolve-by-type, CI wiring, and result parsing live in references/. Use when the target tracker is Linear specifically; for other trackers use jira-bug-workflow-runner (Jira) or github-issues-bug-workflow (GitHub Issues). Files and transitions the issue; reproducing the defect is a separate concern.
