Third-party notice: git-sizer metric definitions and reference values
======================================================================

suites/scale/scalesuite/sizer.py re-implements, in stdlib Python, the metric
set that git-sizer reports, and uses git-sizer's "level of concern" reference
values (one '*' per multiple of the reference value):

  Project:   git-sizer
  Upstream:  https://github.com/github/git-sizer
  Commit:    88eaa80df48db1b47291f3a43b084b8c79082339 (read 2026-09-28)
  Source:    sizes/output.go (metric symbols, descriptions, reference values)

             from the upstream LICENSE.md at the commit above)

What was taken: the metric symbols (uniqueCommitCount ... maxCheckoutSubmoduleCount),
their definitions, and the numeric reference values. No git-sizer source code
was copied or translated; object walking, tree expansion and memoization are
original work of the oak/benchmarks authors built on git plumbing commands.
Stated differences from git-sizer are documented in the sizer module
docstring (object scope; checkout scope above a root-count bound).
