# Mirror the previous flake8 + isort behaviour: pycodestyle (E/W), pyflakes (F)
# and import sorting (I, equivalent to isort profile=black). E203/E501 were
# ignored by flake8; E721 is stricter in ruff than pycodestyle, so keep it off
# to avoid new findings the old tool chain never reported.
# B (bugbear), C4 (comprehensions), PIE and RUF catch real bugs/dead code
# cheaply across the whole tree, including source/.
# UP (pyupgrade) replaces the standalone pyupgrade pre-commit hook - one tool,
# one target-version. ISC (implicit string concat) and RET (flake8-return)
# resolved fully clean across the whole tree with zero manual fixes needed.
# SIM/PERF/T20 were evaluated too, but almost every hit there has no automatic
# fix and would mean hand-rewriting hundreds of loops/prints across source/ -
# deferred to a separate, deliberate cleanup effort rather than bundled here.

# statements across dozens of source/ files for a purely stylistic gain -
# not worth the manual diff right now.
