+- **ACP to A2A module rename and symbol standardization** (#10583 — Epic #8569): Completed the systematic rename of legacy ACP (Agent Communication Protocol) references to A2A (Agent-to-Agent Protocol) throughout the cleveragents.a2a module. All 22 exported symbols now use proper A2A naming conventions per ADR-047. Verified: zero legacy `from cleveragents.acp` imports, no ACP-prefixed classes or functions remain in a2a module files, and all documentation strings reference A2A instead of ACP.

 ### Added
+- **BDD test suite for ACP → A2A module rename** (#10995): Added `a2a_module_rename_standardization.feature` and its step definitions to validate the complete rename of all 22 exported symbols under ADR-047 naming conventions. Includes scenarios verifying export completeness, zero legacy ACP references in source files, and accurate documentation strings.

 * HAL 9000 has contributed the bug-hunt-pool-supervisor non-blocking tracking fix: updated step 5 to be best-effort and added rule 9 to prevent the automation-tracking-manager call from blocking the main supervisor loop.
 * HAL 9000 has contributed the plugin entry point security hardening fix (#7476): enforced entry point allowlist validation before importing plugin modules to prevent malicious plugin loading.
 * HAL 9000 has contributed the benchmark workflow separation (#9040): moved the benchmark-regression job out of the default PR workflow into a dedicated scheduled workflow, reducing median PR CI turnaround time from 99-132 minutes to under 30 minutes.
+* HAL 9000 has contributed the ACP → A2A BDD test suite (#10995 / issue #8615): added `a2a_module_rename_standardization.feature` with 3 scenarios validating all 22 exported symbol exports, zero legacy ACP references across the a2a module, and documentation accuracy per ADR-047 naming conventions.
 * HAL 9000 has contributed the agent-evolution-pool-supervisor PR metadata assignment (#7888): the supervisor now automatically looks up the Type/Automation label and earliest open milestone before dispatching improvement PR creation workers, ensuring all generated improvement PRs have correct Type labels and milestone assignments.
 * This project was made possible thanks to considerable donation of time, money, and resources by CleverThis, Inc.
 * HAL 9000 has contributed automated bug fixes, CLI output formatting improvements, and ongoing maintenance as part of the CleverAgents automation system.

 * HAL 9000 has contributed the LLMTraceRepository data-integrity fix (PR #8185 / issue #7505): replaced the unconditional `session.commit()` in `LLMTraceRepository.save()` with a dual-path implementation that respects the UnitOfWork pattern — flushing only when an external session is provided, and flushing + committing + closing when operating standalone. This eliminates premature transaction commits, loss of rollback capability, and a docstring/implementation mismatch.
 * HAL 9000 has contributed the ACMS Index Data Model and File Traversal Engine (PR #9664 / issue #9579): foundational data structures for indexed context entries with hot/warm/cold/archive storage tier classification, tag system, and a timeout-safe chunked file traversal engine for large projects with 10,000+ files.
 
-* HAL 9000 has contributed the error-suppression removal fix (PR #9247 / issue #9060): removed both `try...except Exception:` blocks in `register_registry_agents()` that silently suppressed errors from `actor_registry.list_actors()` and the route bridge refresh, enabling exceptions to propagate per CONTRIBUTING.md fail-fast policy. Added three Behave scenarios verifying RuntimeError, AttributeError, and TypeError propagation.

+Feature: ACP to A2A module rename and symbol standardization
+  As a CleverAgents developer
+  I want the ACP → A2A module rename to be fully validated via BDD tests
+  So that no legacy ACP references remain and all exports follow ADR-047 naming
+
+  Background:
+    Given the "a2a" Python package is importable from "cleveragents.a2a"
+
+  Scenario: All 22 __all__ symbols are exported and importable via a2a package
+    When I import "cleveragents.a2a"
+      And all of the following 22 symbols should be importable from it:
+        | A2aError              |
+        | A2aErrorDetail        |
+        | A2aEvent              |
+        | A2aEventQueue         |
+        | A2aHttpTransport      |
+        | A2aLocalFacade        |
+        | A2aNotAvailableError  |
+        | A2aOperationNotFoundError |
+        | A2aRequest            |
+        | A2aResponse           |
+        | A2aStdioTransport     |
+        | A2aVersion            |
+        | A2aVersionMismatchError |
+        | A2aVersionNegotiator  |
+        | AuthClient            |
+        | RemoteExecutionClient |
+        | ServerClient          |
+        | ServerConnectionConfig|
+        | StubAuthClient        |
+        | StubRemoteExecutionClient |
+        | StubServerClient      |
+        | TransportSelector     |
+    Then every symbol should resolve to a non-None object
+    And the count of exported symbols should equal 22
+
+  Scenario: Zero ACP references remain in the a2a module source files
+    When I recursively scan all Python files under "src/cleveragents/a2a"
+      And I search for the legacy prefix string "ACP"
+    Then zero instances of "ACP" should be found
+    And this confirms the complete ACP → A2A rename is clean
+
+  Scenario: Documentation strings use A2A naming per ADR-047
+    When I read the docstring of the "cleveragents.a2a" package
+    Then it should contain the term "A2A (Agent-to-Agent Protocol)"
+    And it should reference "ADRs" or "ADR-047" for standard adoption
+    And the docstring should NOT contain any mentions of "ACP protocol"
