0002 """segfault-findings-serials.py — permanent ids for the findings written
0003 before serials existed.
0004
0005 A finding draws its serial (data['serial'], shown as f-n) once, when it is
0006 written (monitor_app/segfaults.py, set_finding). The findings written
0007 before 2026-09-12 have none; this assigns them in creation order and
0008 prints what it assigned. Idempotent: a finding with a serial is left as
0009 it is.
