+- **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.

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

+    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 A2aRequest
+    And I should have access to A2aResponse

+    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
