Benchmark data:

  benchmarks/ fetches source from qutebrowser (GPL-3.0-or-later) at runtime
  for verification purposes only. No GPL source code is vendored in this
  repository.

Copyleft fingerprint index (data/copyleft.db):

  This SQLite database contains *derived integer fingerprints* (winnowing
  hashes) computed from copyleft-licensed open-source projects, together with
  per-chunk metadata (project name, SPDX license id, source URL). It does NOT
  contain any original source code — only irreversible hashes — so it is not a
  derivative distribution of that code in source form. The projects whose
  fingerprints are indexed are GPL/AGPL-licensed (qutebrowser, ansible,
  OctoPrint, searxng, Radicale, ranger, buildbot, weblate, gramps); each entry
  records its own license and origin URL.
