+- **A2A module rename BDD test suite** (#8615): Comprehensive Behave tests validating that the ACP→A2A module rename is complete — verifying all 22 A2A symbols are properly exported, no legacy ACP references remain in `.py` files under `cleveragents.a2a/`, and the module docstring uses current A2A naming. The step definitions include self-contained symbol lookups to avoid cross-scenario dependency failures.

 * HAL 9000 has contributed database resource types (PostgreSQL, SQLite) with transaction-based sandbox strategy: implemented ``DatabaseResourceHandler`` providing full CRUD operations (`read`, `write`, `delete`, `list_children`) and connection validation with automatic credential masking for PostgreSQL and SQLite backends. Includes ``TransactionSandbox`` infrastructure wired into ``SandboxFactory``, BDD test coverage in ``features/database_resources.feature``, and Robot Framework integration tests in ``robot/database_resources.robot`` (PR #10591 / issue #8608, Epic #8568).

Supported by `--yes/-y`, `--to-checkpoint`, and `--format/-f` flags. Includes comprehensive BDD test coverage (>= 97%) for rollback, decision discarding, and plan resume functionality.

+Feature: A2A Module Rename and Symbol Standardization
+  As a developer
+  I want all A2A symbols to be standardized
+  So that the codebase uses consistent A2A naming conventions
+
+  Scenario: A2A module exports all required symbols
+    When I import from cleveragents.a2a
+    Then I should have access to A2aError
+    And I should have access to A2aErrorDetail
+    And I should have access to A2aEvent
+    And I should have access to A2aEventQueue
+    And I should have access to A2aHttpTransport
+    And I should have access to A2aLocalFacade
+    And I should have access to A2aNotAvailableError
+    And I should have access to A2aOperationNotFoundError
+    And I should have access to A2aRequest
+    And I should have access to A2aResponse
+    And I should have access to A2aStdioTransport
+    And I should have access to A2aVersion
+    And I should have access to A2aVersionMismatchError
+    And I should have access to A2aVersionNegotiator
+    And I should have access to AuthClient
+    And I should have access to RemoteExecutionClient
+    And I should have access to ServerClient
+    And I should have access to ServerConnectionConfig
+    And I should have access to StubAuthClient
+    And I should have access to StubRemoteExecutionClient
+    And I should have access to StubServerClient
+    And I should have access to TransportSelector
+
+  Scenario: A2A module has no ACP references
+    When I check the A2A module for ACP references
+    Then there should be no ACP imports
+    And there should be no ACP class names
+    And there should be no ACP function names
+
+  Scenario: A2A module is properly documented
+    When I check the A2A module documentation
+    Then the module docstring should mention A2A
+    And the module docstring should not mention ACP
