# Testing utilities
#
# AUDIT EV-74: proptest migrated its internal RNG stack to rand 0.9 in the
# 1.7.0 release. proptest >= 1.7 therefore pulls in a *second* major of the
# RNG stack (rand 0.9 / rand_core 0.9 / rand_chacha 0.9 via rand_xorshift's
# TestRng) alongside our own direct rand 0.8 stack (rand 0.8.5 / rand_core
# 0.6.4 / rand_chacha 0.3.1, used by fugue-evo, fugue-ppl, and rand_distr),
# duplicating the RNG-stack compile units in dev/test builds.
#
# The 1.5.x / 1.6.x line still uses rand 0.8, so we pin below 1.7 to collapse
# the duplication. Verified empirically: `cargo update -p proptest --precise
# 1.6.0` removes rand 0.9.2 / rand_chacha 0.9.0 / rand_core 0.9.3 entirely,
# after which `cargo tree -d` reports a single rand major (0.8.5) and
# `cargo check --all-targets` + the full property-test suite still pass. The
# `Makefile`'s `deps-check` target runs `cargo tree -d` in CI to catch any
# future reintroduction of a duplicate rand major. Revisit (dropping the
# upper bound and migrating our own rand_distr/rand_chacha usage to 0.9) if we
# ever need a proptest >= 1.7 feature.
