A task that reached the router's MaxAttempts was permanently terminal.
TaskReleased only ever increments Attempt, TaskCorrected could not touch it,
and no HTTP route emitted a correction at all. The only way to work an
exhausted issue again was to invent a second task for it, which defeats
(source, external_id) dedupe and abandons the task's own history.
POST /v1/tasks/{id}/retry, full-control surfaces only. It requires the task
to be failed, unleased, and failed with reason retry_limit: restoring a retry
budget is not an answer to a failure that was not the budget running out. The
effect is one TaskCorrected naming that failure, setting state queued and
attempt 0 and clearing next_retry_at, failure_class and last_error. Task id,
source pair, goal, acceptance, decisions, work phase and artifact refs all
stay, and the original failure events stay in the log.
operation_id is required and makes the call idempotent, so a repeated request
cannot reset an attempt that has since started running.
This is RetryTask, not a generic correction endpoint: arbitrary task mutation
over HTTP is a different and much larger authority. It also does not address
F9, which is an operator releasing a lease someone else owns.
