Compiled by the generic-dtc-db workflow (P0/U0/C0/B0 standard codes, system
tags + no-start flags). Lives in profiles/_data/generic-dtcs.json (bundled with
profiles/, not listed as a vehicle profile). DtcDatabase.get now falls back:
profile code -> generic code -> unknown, so any standard code resolves to a
description while vehicle profiles still override (e.g. P0148 keeps the 6.0 text).
