+Feature: Coverage threshold configuration
+  The project enforces a minimum 97% code coverage threshold across multiple
+  configuration files. This feature validates that pyproject.toml, noxfile.py,
+  the CI workflow, and the nightly quality workflow are all correctly configured
+  to enforce and report coverage thresholds.
+
+  # -- pyproject.toml coverage configuration --
+
+  Scenario: Coverage run section exists in pyproject.toml
+    Given the pyproject toml file is loaded for coverage check
+    Then the coverage run section should exist
+
+  Scenario: Coverage source includes src directory
+    Given the pyproject toml file is loaded for coverage check
+    Then the coverage source should include "src"
+
+  Scenario: Coverage branch tracking is enabled
+    Given the pyproject toml file is loaded for coverage check
+    Then the coverage branch tracking should be enabled
+
+  Scenario: Coverage data file is stored under build directory
+    Given the pyproject toml file is loaded for coverage check
+    Then the coverage data file should be "build/.coverage"
+
+  Scenario: Coverage HTML report directory is under build
+    Given the pyproject toml file is loaded for coverage check
+    Then the coverage html directory should be "build/htmlcov"
+
+  Scenario: Coverage XML output is under build directory
+    Given the pyproject toml file is loaded for coverage check
+    Then the coverage xml output should be "build/coverage.xml"
+
+  Scenario: Coverage omit patterns exclude test directories
+    Given the pyproject toml file is loaded for coverage check
+    Then the coverage omit patterns should include "*/tests/*"
+
+  # -- noxfile.py coverage session --
+
+  Scenario: Noxfile defines a coverage_report session
+    Given the noxfile py is loaded for coverage check
+    Then the noxfile should define a coverage_report session
+
+  Scenario: Noxfile enforces fail-under threshold of at least 97
+    Given the noxfile py is loaded for coverage check
+    Then the noxfile should contain a fail-under threshold of at least 97
+
+  # -- CI workflow coverage enforcement --
+
+  Scenario: CI workflow references nox coverage_report session
+    Given the ci workflow file is loaded for coverage check
+    Then the ci workflow should reference nox coverage_report session
+
+  # -- Nightly quality workflow coverage enforcement --
+
+  Scenario: Nightly workflow enforces coverage threshold via --coverage-min
+    Given the nightly quality workflow file is loaded for coverage check
+    Then the nightly workflow should use a fail-under of at least 85
