description: >
  Analyse 500+ log lines from 3 services to identify the root cause of a cascading
  failure. Two red herrings are present: a high-error-rate batch job (expected,
  documented) and clock-skew that makes svc_c appear to fail before svc_b.
  Produce root_cause_report.json with timeline, root cause, and false-lead explanations.
