GET /tasks/:id — get full task details and state

The GET /tasks/:id endpoint returns the complete state of a single task. Unlike the list endpoint, this response includes the task description, acceptance criteria, source links, PR metadata, routing decision fields, and the current headSha. Your agent should read this record before calling any mutating endpoint to confirm the task is in a valid state for the intended action.

Error responses

Status	Code	Meaning
`401`	`unauthorized`	Bearer token is missing or invalid.
`403`	`insufficient_scope`	Key does not have `tasks:read`.
`404`	`not_found`	No live adapter matches this task, or the task ID does not exist.

Always check data.availableActions before calling a mutating endpoint. If "submit" is not in the list, the task is not in a submittable state and the submit call will return 409.
