When the Paperclip pod restarts mid-run, the in-process setInterval keepalive dies, `updatedAt` goes stale, and the server's orphan reaper fails the run with the (misleading) "child pid 1 is no longer running" message. Paperclip then dispatches a continuation run, whose execute() finds the previous run's K8s Job still happily running and deletes it as an "orphan" — throwing away work and producing the transcript/run cascade reported on FAR-124. Changes: - job-manifest: add `paperclip.io/task-id` and `paperclip.io/session-id` labels (sanitized via new `sanitizeLabelValue` helper) so a later execute() can identify an orphan as the continuation of the same logical unit of work. - execute: in the concurrency guard, when `reattachOrphanedJobs` is on (default) and an orphan matches agent + task + session + is not terminal, pick it as the reattach target; delete only the other orphans. Branch the build/create/waitForPod block so the reattach path skips manifest building, Secret creation, Job creation, and scheduling wait — it jumps straight to streaming logs and waiting for the existing pod's completion. - config-schema: expose `reattachOrphanedJobs` toggle (default true). - Tests: `sanitizeLabelValue`, `isReattachableOrphan`, new label presence/absence, config default. No server-side changes; the misleading reaper message and lack of a non-local retry path will be addressed in a follow-up upstream PR. Co-Authored-By: Paperclip <noreply@paperclip.ing>
