+# TubeInitializationTest.feature - Initialization and Logging Tests for Atomic Tubes
+#
+# This feature file contains critical Above the Line (ATL) tests for the initialization
+# and logging of atomic base tubes in Samstraumr. These tests validate the integrity,
+# uniqueness, and self-contained nature of a tube's identity and operations. All ATL tests
+# must pass before proceeding to any further testing stages.
+#
+# Running Tests from the Command Line:
+#
+# To run all tests in this feature file:
+#   mvn test -Dcucumber.filter.tags="@ATL"
+#
+# To run specific groups of tests:
+#   Use tags to target individual scenarios or categories of features.
+#
+# Example: Running only the UUID-related tests:
+#   mvn test -Dcucumber.filter.tags="@UUID"
+#
+# Available Tags:
+#   @ATL           - Above the Line tests (P0 priority, must pass for further testing)
+#   @Initialization - Tests related to the initialization process of Tubes
+#   @UUID          - Tests concerning the generation and uniqueness of Tube UUIDs
+#   @Logging       - Tests verifying the logging functionality of Tubes
+#   @ErrorHandling - Tests validating the error handling mechanisms of Tubes
+#   @Encapsulation - Tests ensuring Tube isolation and self-containment
+#
+# Best Practices for Running Tests:
+#   - Always start with @ATL tests before proceeding to any Below the Line (BTL) tests.
+#   - Use specific tags to focus on particular areas of concern when troubleshooting.
+#   - Review logs for queryable timestamps and reasons in case of failure.
+#   - Ensure your environment is properly configured and ready before running the tests.

 Feature: Tube Initialization and Logging
+  # This feature verifies that the atomic base tube (Tube.java) initializes correctly, ensuring that it operates
+  # within its assigned environment, generates a unique identity (UUID), logs relevant details, and remains self-contained.
+  # These tests are essential for validating that the Tube can function in isolation, without interacting
+  # with external systems, which sets the stage for further tests involving Composite Tubes and Machines.
+
+  @ATL @Initialization @UUID @Logging
+  Scenario: Tube initializes with a unique ID and environment details
+    # The core reason behind this test is to confirm that the atomic Tube can initialize correctly with its
+    # environment, generate a unique identity, and log relevant information. This is a P0 test because without a
+    # valid identity and environment awareness, nothing else in Tube-Based Design (TBD) would function correctly.
+    Given the operating environment is ready
+    When a new Tube is instantiated with reason "Test Initialization"
+    Then the Tube should initialize with a unique UUID
+    And the Tube should log its environment details
+    And the Tube should log the reason "Test Initialization"
+    And the Tube log should be queryable
+
+  @ATL @Initialization @ErrorHandling @FaultTolerance
+  Scenario: Tube initialization fails gracefully when the environment is invalid
+    # This test verifies that the Tube can handle failures during initialization, such as an invalid or corrupted
+    # operating environment. Handling errors gracefully is crucial to ensure the system does not crash when individual
+    # tubes encounter issues. This P0 test guarantees fault tolerance at the atomic level.
+    Given the operating environment is invalid
+    When a new Tube is instantiated with reason "Invalid Environment Test"
+    Then the Tube initialization should fail with a "EnvironmentInitializationException"
+    And the Tube should log the failure with the reason "Invalid Environment Test"
+    And the log should capture the specific error message "Environment initialization failed"
+    And the Tube log should be queryable
+
+  @ATL @UUID @Uniqueness @Boundary
+  Scenario: Tube generates a truly unique UUID across multiple instantiations
+    # This test ensures that each Tube receives a unique identity across multiple instances. This is a foundational
+    # principle in Tube-Based Design. The uniqueness of each Tube ensures that systems can track, trace, and interact
+    # with them without confusion or duplication. This is a priority 0 test.
+    Given the operating environment is ready
+    When multiple Tubes are instantiated simultaneously
+    Then each Tube should have a unique UUID
+    And no two Tubes should share the same UUID
+    And all Tube logs should be queryable for their UUIDs
+
+  @ATL @Logging @Querying
+  Scenario: Tube logs are generated in real-time and are queryable
+    # Logging is critical for visibility into Tube operations. This test verifies that logs are generated immediately
+    # upon Tube initialization and are queryable. Without this, debugging and tracking a Tube's lifecycle would be
+    # near impossible. Another P0 test.
+    Given the operating environment is ready
+    When a new Tube is instantiated with reason "Log Query Test"
+    Then the Tube should log its initialization details immediately
+    And the Tube logs should be queryable by timestamp
+    And the logs should contain the reason "Log Query Test"
 
+  @ATL @Encapsulation @SelfContainment
+  Scenario: Tube is self-contained and does not attempt external communications
+    # This test ensures that the atomic Tube does not interact with any external systems. The purpose of an atomic Tube
+    # is to interface only with its host OS and any Tubes directly connected to it. This test reinforces that there are
+    # no unwanted external communications, reinforcing the integrity of Tube-based isolation.
+    Given the operating environment is ready
+    When a new Tube is instantiated with reason "Self-Containment Test"
+    Then the Tube should not establish any external network connections
+    And the Tube should not log any external communication attempts
+    And all Tube operations should remain confined to its internal environment
