# tests/test_install_profile_russia.sh — CL-4: --profile=russia wiring tests
#
# Covers:
#   1. args_parse accepts --profile=russia (= form)
#   2. args_parse rejects --profile russia (space form; unsupported, =form only)
#   3. args_parse --profile foo dies with an error
#   4. args_parse with no --profile sets PROFILE empty
#   5. install.sh calls split_routing_run ONLY when PROFILE=russia
#   6. install.sh does NOT call split_routing_run when no --profile
#   7. install.sh sources install-split-routing.sh in the lib-source block
#   8. install-args.sh usage text mentions --profile
#
# TDD ref: CL-4 deliverable (feat/split-routing-install-wiring)
# Plan ref: the operator's internal Russia-profile installer plan (2026-05-09)
