Distributed Job Safety

Patterns and anti-patterns for concurrent job management with pueue + mise + systemd-run, learned from production failures in distributed data pipeline orchestration.

Scope: Universal principles for any pueue + mise workflow with concurrent parameterized jobs. Examples use illustrative names but the principles apply to any domain.

Prerequisite skills: devops-tools:pueue-job-orchestration, itp:mise-tasks, itp:mise-configuration

Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
