    Skip the network integration test on Windows where the WASM
    sandbox lacks the encodings.idna codec.

    - Fix stale output: clear output_dir before each sandbox.run() call
    - Fix blocking event loop: _run_code now async with asyncio.to_thread()
    - Revert _agents.py options['tools'] injection (unnecessary; provider
      uses context.extend_tools())
    - Revert SessionContext.options docstring back to read-only
    - Add real-sandbox test fixtures (shared/restored/fresh)
    - Add 8 new real-sandbox tests for callback round-trip, stale output,
      event loop non-blocking, basic execution, stdout/stderr, errors,
      snapshot/restore, and tool registration
    - Add comprehensive .NET HyperlightCodeActProvider design document

    context provider, standalone tool, manual static wiring, and file
    mounts / network access patterns.

    - OllamaEmbeddingClient: Text embeddings via Ollama's embed API
    - BedrockEmbeddingClient: Text embeddings via Amazon Titan on Bedrock
    - AzureAIInferenceEmbeddingClient: Text and image embeddings via Azure AI
      Inference, supporting Content | str input with separate model IDs for
      text (AZURE_AI_INFERENCE_EMBEDDING_MODEL_ID) and image
      (AZURE_AI_INFERENCE_IMAGE_EMBEDDING_MODEL_ID) endpoints
    
    Additional changes:
    - Rename EmbeddingCoT -> EmbeddingT, EmbeddingOptionsCoT -> EmbeddingOptionsT
    - Add otel_provider_name passthrough to all embedding clients
    - Register integration pytest marker in all packages
    - Add lazy-loading namespace exports for Ollama and Bedrock embeddings

    * updates from feedback
    
    * Fix CI failures in embedding usage handling
    
    - Fix Azure AI embedding mypy issues by normalizing vectors to list[float],
      safely accumulating optional usage token fields, and filtering None entries
      before constructing GeneratedEmbeddings
    - Avoid Bandit false positive by initializing usage details as an empty dict
    - Update OpenAI embedding tests to assert canonical usage keys
      (input_token_count/total_token_count)

    * updated integration tests
    
    * fix: remove duplicate --dist loadfile flag from pytest-xdist config
    
    Only one --dist mode can be active at a time; the second value silently
    overrides the first. Keep --dist worksteal (dynamic load balancing) and
    remove the redundant --dist loadfile from all workflow files and
    pyproject.toml configs.

    Both python-merge-tests.yml and python-integration-tests.yml share the

    comments, the python-testing SKILL.md, and CODING_STANDARD.md.

    * refactor: remove RUN_INTEGRATION_TESTS flag
    
    Integration test gating now uses two mechanisms:
    - `@pytest.mark.integration` for test selection via `-m` filtering
    - `skip_if_*_disabled` for credential/service availability checks
    
    The RUN_INTEGRATION_TESTS env var was redundant since the marker handles
    selection and the skip decorators already check for actual credentials.

  • Python: feat(python): Add embedding abstractions and OpenAI implementation (Phase 1) (#4153)
    * feat(python): Add embedding abstractions and OpenAI implementation (Phase 1)
    
    This PR contains two parts:
    
    1. **Overall migration plan** for porting vector stores and embeddings from
       Semantic Kernel to Agent Framework (docs/features/vector-stores-and-embeddings/README.md)
       covering all 10 phases from core abstractions through connectors and TextSearch.
    
    2. **Phase 1 implementation** — core embedding abstractions and OpenAI/Azure OpenAI
       embedding clients:
    
       Core types (_types.py):
       - EmbeddingGenerationOptions TypedDict (total=False)
       - Embedding[EmbeddingT] generic class with model_id, dimensions, created_at
       - GeneratedEmbeddings[EmbeddingT, EmbeddingOptionsT] list container with options, usage
       - EmbeddingInputT (default str) and EmbeddingT (default list[float]) TypeVars
    
       Protocol + base class (_clients.py):
       - SupportsGetEmbeddings protocol — Generic[EmbeddingInputT, EmbeddingT, OptionsContraT]
       - BaseEmbeddingClient ABC — Generic[EmbeddingInputT, EmbeddingT, OptionsCoT]
    
       Telemetry (observability.py):
       - EmbeddingTelemetryLayer with gen_ai.operation.name = "embeddings"
    
       OpenAI implementation (openai/_embedding_client.py):
       - RawOpenAIEmbeddingClient, OpenAIEmbeddingClient, OpenAIEmbeddingOptions
       - Uses _ensure_client() factory pattern
    
       Azure OpenAI implementation (azure/_embedding_client.py):
       - AzureOpenAIEmbeddingClient following AzureOpenAIChatClient pattern
       - Supports API key, Entra ID credentials, env var configuration
    
       Tests:
       - 47 unit tests for types, protocol, base class, OpenAI, and Azure clients
       - 6 integration tests (gated behind RUN_INTEGRATION_TESTS + credentials)
    
       Samples:
       - samples/02-agents/embeddings/openai_embeddings.py
       - samples/02-agents/embeddings/azure_openai_embeddings.py

    * fix: Handle base64 encoding_format in OpenAI embedding client
    
    When encoding_format='base64' is used, the OpenAI API returns base64-encoded
    floats instead of a JSON array. Decode these automatically to list[float]
    so the return type stays consistent regardless of encoding format.
    
    Also adds a unit test for base64 decoding and fixes minor docstring/import issues.

    * fix: Only record INPUT_TOKENS for embedding telemetry
    
    Embeddings have no output/completion tokens. Remove OUTPUT_TOKENS recording
    which was double-counting prompt_tokens via the total_tokens fallback.

    * fix: Resolve mypy variance error and lint warning
    
    Use contravariant/covariant TypeVars for SupportsGetEmbeddings Protocol.
    Combine nested if into single statement in telemetry layer.

    * fix: Make EmbeddingCoT invariant for mypy compatibility
    
    GeneratedEmbeddings is invariant in its type param, so the Protocol
    TypeVar cannot be covariant.

    * fix: Address PR review - empty values guard, service_url for telemetry
    
    - Add early return for empty values in get_embeddings to avoid unnecessary API calls
    - Add service_url() method to RawOpenAIEmbeddingClient for proper telemetry endpoint reporting
    - Add test for empty values behavior

    * Python: Fix OpenAI chat client compatibility with third-party endpoints and OTel 0.4.14 (#4161)
    
    * Fix system message content sent as list instead of string
    
    Some OpenAI-compatible endpoints (e.g. NVIDIA NIM) reject system messages
    when content is a list of content parts. This change flattens system and
    developer message content to a plain string in the Chat Completions client.
    
    Fixes https://github.com/microsoft/agent-framework/issues/1407

    * Fix compatibility with opentelemetry-semantic-conventions-ai 0.4.14
    
    Version 0.4.14 removed several LLM_* attributes from SpanAttributes
    (LLM_SYSTEM, LLM_REQUEST_MODEL, LLM_RESPONSE_MODEL, LLM_REQUEST_MAX_TOKENS,
    LLM_REQUEST_TEMPERATURE, LLM_REQUEST_TOP_P, LLM_TOKEN_TYPE).
    
    Move these to the OtelAttr enum with their well-known gen_ai.* string values
    and update all references in observability.py and tests.

    * Flatten text-only message content to string for all roles
    
    Extend the system/developer fix to all message roles. Text-only content
    lists are now post-processed into plain strings, while multimodal content
    (text + images/audio) remains as a list. This fixes compatibility with
    OpenAI-like endpoints that cannot deserialize list content (e.g. Foundry
    Local's Neutron backend).

    * Fix streaming text lost when usage data in same chunk
    
    Some providers (e.g. Gemini) include both usage data and text content
    in the same streaming chunk. The early return on chunk.usage caused
    text and tool call parsing to be skipped entirely. Remove the early
    return and process usage alongside text/tool calls.
    
    Fixes https://github.com/microsoft/agent-framework/issues/3434

    * Fix mypy errors in _chat_client.py
    
    Rename shadowed variable 'args' in system/developer branch to 'sys_args'
    and rename loop variable 'content' to 'msg_content' to avoid type conflict.

    * fix: Clear env vars in construction tests to avoid CI leakage

    env vars from the integration test environment don't prevent the expected
    ValueError from being raised.
