rust-validation-tests.yml

# Dedicated workflow for validation scenario tests that require sequential execution.
#
# These tests spin up full pipelines with Docker containers and compete for
# system resources when run in parallel. They are gated behind the custom
# `validation_tests` cfg flag and excluded from the main Rust-CI workflow.
#
# Tests must be prefixed with `validation_` to be selected by the nextest
# filter expression.
#
# Trigger manually from the GitHub Actions UI.
