# Upstream pins dask/distributed to an exact RAPIDS-tested snapshot
# (>=2026.1.1,<2026.1.2). That cap is NOT functionally load-bearing for
# this release: the package's whole runtime job is to import-hook dask
# and distributed and apply version-specific monkeypatches, but in
# 26.6.0 both patch entrypoints are no-ops
# (patches/{dask,distributed}/__init__.py call
# make_monkey_patch_loader(..., lambda _: None)), so nothing is keyed to
# the exact dask version. We relax the upper cap (see src_prepare) so the
# shim coexists with our dev-python/dask-2026.3.0 rather than forcing a
# downgrade. verified 2026-06-10
