Walkthrough

The pull request enforces import sorting standards by adding the I001 Ruff linting rule to pyproject.toml and systematically reordering imports across the codebase to comply with these standards. Additionally, a comprehensive unit test suite for the A2A endpoint module is added. No runtime logic, control flow, or public API signatures are altered.

Changes

Cohort / File(s)	Summary
Linting Configuration pyproject.toml	Added I001 import sorting rule to Ruff lint configuration extend-select.
Core Source Files dev-tools/mcp-mock-server/server.py, dev-tools/mcp-mock-server/test_mock_mcp_server.py, scripts/gen_doc.py, scripts/generate_openapi_schema.py	Reordered import statements to enforce consistent import ordering (e.g., datetime/UTC, http.server classes, module imports).
Mock Server Files tests/e2e/mock_jwks_server/generate_tokens.py, tests/e2e/mock_jwks_server/server.py, tests/e2e/mock_mcp_server/server.py	Reordered imports from http.server, cryptography, and other modules for consistency.
E2E Test Utilities & Steps tests/e2e/features/environment.py, tests/e2e/features/steps/*, tests/e2e/utils/llama_stack_utils.py, tests/e2e/utils/prow_utils.py	Reordered and reorganized imports; added blank line separations between stdlib and third-party imports where appropriate.
Benchmark Tests tests/benchmarks/conftest.py, tests/benchmarks/db_benchmarks.py, tests/benchmarks/test_app_database.py, tests/benchmarks/test_app_database_comparison.py	Reordered imports from configuration, datetime, SQLAlchemy, and test module imports.
Unit Test - A2A Endpoint tests/unit/app/endpoints/test_a2a_.py	Added comprehensive unit test suite (~895 lines) covering A2A protocol endpoint functionality, including fixtures, request/response handling, task execution, streaming, error cases, and authorization tests. Imported and reordered existing test file imports in test_a2a.py accordingly.
Unit Tests - Endpoints tests/unit/app/endpoints/test_*.py	Reordered imports across all endpoint test files; expanded imports in test_streaming_query.py to include additional response chunk types and aliases from llama_stack_api.openai_responses; reorganized test_responses.py imports into separate statements.
Unit Tests - Models & Config tests/unit/models/config/test_*.py, tests/unit/models/requests/test_*.py, tests/unit/models/responses/test_*.py, tests/unit/models/rlsapi/test_*.py	Systematically reordered imports across configuration, request, response, and RLSAPI test modules; consolidated duplicate imports and adjusted import grouping.
Unit Tests - Other Modules tests/unit/app/test_*.py, tests/unit/authentication/test_*.py, tests/unit/authorization/test_*.py, tests/unit/cache/test_*.py, tests/unit/quota/test_*.py, tests/unit/telemetry/test_*.py, tests/unit/utils/test_*.py, tests/unit/test_*.py	Reordered imports across authentication, authorization, cache, quota, observability, and utility test modules; adjusted blank-line formatting and grouped related imports.
Integration Tests tests/integration/conftest.py, tests/integration/endpoints/test_*.py, tests/integration/test_*.py	Consolidated and reordered imports; moved stdlib imports to align with others; reorganized SQLAlchemy, configuration, and endpoint handler imports.

Sequence Diagram(s)

No sequence diagrams generated—the changes are primarily import reordering and configuration updates, not functional logic modifications with multi-component interactions.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

The PR consists mainly of homogeneous, repetitive import reordering across ~90+ files, which reduces per-file review complexity. However, the addition of a comprehensive A2A endpoint test suite (~895 lines) introduces moderate complexity requiring careful validation of test coverage, fixtures, and assertion logic. The broad scope across multiple modules and the need to verify import correctness in context warrant moderate review effort.

Possibly related PRs

• LCORE-1476: fixed unsorted imports in sources #1369: Both PRs perform broad import-order refactors across the repository to enforce sorted imports, with overlapping changes to many of the same modules (datetime/UTC reorderings, http.server import reorders), making them closely related enforcement efforts.
