    description: 'Write /workspace/docs/postmortem-2026-07-24.md with headings Summary, Timeline, Root cause, Impact, Action items, and What went well. Root cause must mention redis. Action items must include a concrete follow-up containing validate or validation. Do not blame a person by name.'
    hints:
      - 'Keep it blameless: systems and process, not individuals.'
      - Timeline should reflect deploy then errors then rollback.
      - 'Action items example: add compose config validation in CI.'
