# frozen_string_literal: true

# SimpleCov configuration for the system extension.
#
# Opt-in via COVERAGE=1. If COVERAGE=1 is set but the simplecov gem isn't
# installed (i.e., the parent platform's Gemfile doesn't include it), the
# require fails gracefully with a warning — tests still run, just no coverage.
#
# To enable coverage in CI or locally:
#   1. Add to the parent platform's server/Gemfile:
#        gem 'simplecov', require: false, group: :test
#   2. Run: bundle install
#   3. Require this file at the top of spec_helper.rb (FIRST require), e.g.:
#        require_relative '../../extensions/system/server/spec/support/simplecov'
#   4. Invoke:
#        COVERAGE=1 bundle exec rspec ../extensions/system/server/spec
#   5. Open coverage/system_extension/index.html
#
# The minimum_coverage gate starts permissive (60%) so the gate doesn't block
# while the test pyramid is being built out (per audit plan P0.1, P0.2, P2.1,
# P2.2). Tighten to 70% after wave 3 of P0.1 controllers, 80% after wave 5.
