    * Add Python parity sample for invoking Foundry Toolbox tools from declarative workflows
    
    * Python: address PR review on declarative toolbox sample
    
    Two security fixes for PR #5933:
    
    1. Add safe_mode flag to WorkflowFactory (default True) mirroring
       AgentFactory. Gates =Env.* exposure inside DeclarativeWorkflowState
       PowerFx symbols via _safe_mode_context, so workflow YAML loaded from
       untrusted sources no longer leaks the host's full os.environ snapshot
       into PowerFx evaluation. The flag is also forwarded to the
       internally-constructed AgentFactory so inline agent definitions
       follow the same policy.
    
    2. Pin the invoke_foundry_toolbox_mcp sample's _client_provider to the
       resolved toolbox endpoint. The bearer-authenticated httpx client is
       now only returned when MCPToolInvocation.server_url matches the
       toolbox URL case-insensitively; any other URL gets None (the default
       unauthenticated path), preventing the Foundry AAD bearer token from
       being attached to a mis-configured or injected server URL. Mirrors
       the .NET sample's httpClientProvider guard.
    
    The sample is updated to opt in to safe_mode=False because its YAML
    intentionally uses =Env.FOUNDRY_TOOLBOX_* to keep configuration in env
    vars under the developer's control.

    * Python: bump package versions for 1.2.2 release
    
    PATCH bump (1.2.1 -> 1.2.2) for the released cohort. Five PRs land in this
    window:
    
    - agent-framework-openai: fix file_search citations breaking the assistant-
      message history roundtrip (#5557) — drives the released-tier PATCH
    - agent-framework-orchestrations: [BREAKING] standardize orchestration
      terminal outputs as AgentResponse (#5301)
    - agent-framework-core, agent-framework-declarative: preserve Workflow.run()
      shared state across calls, accept list[Message] in declarative start
      executor, and coerce Enum values when serializing PowerFx symbols (#5531)
    - agent-framework-foundry-hosting: add hosted Durable Workflow support
      (#5531)
    - agent-framework-azure-contentunderstanding: new alpha package — Azure AI
      Content Understanding context provider (#4829)
    - dependencies: workspace package dependency refresh (#5555)
    
    Per lockstep convention, all 21 beta packages stamp 1.0.0b260429 and all 4
    alpha packages (now including the new contentunderstanding) stamp
    1.0.0a260429. Date stamp reflects 2026-04-29 Pacific. Every non-core package
    floor on agent-framework-core is raised to >=1.2.2; the new
    contentunderstanding package's stale >=1.0.0 floor is brought into line.
    
    Two follow-on fixes bundled to keep validate-dependency-bounds-test green
    at lowest-direct resolution:
    - Bump agent-framework-azure-contentunderstanding's azure-ai-content
      understanding lower bound from >=1.0.0 to >=1.0.1 (1.0.0 ships without
      proper typing — pyright reports 65 unknown-type errors)
    - Add pyright ignore comments to core/foundry/__init__.pyi for the new
      alpha package's type-stub imports, since alpha packages are not in
      core's [all] extra and therefore aren't installed at lowest-direct
    
    * Python: add #5552 to 1.2.2 CHANGELOG
    
    Add the streaming-span observability fix to the Fixed section. PR is on
    upstream/main but not yet pulled into origin/main; the code itself will
    land via the PR merge.
    
    * Python: address PR #5561 review feedback on dependency bounds
    
    Two packaging fixes flagged in review:
    
    1. agent-framework-azure-contentunderstanding: add agent-framework-foundry
       as a runtime dependency. The package's README directs users to
       `pip install agent-framework-azure-contentunderstanding --pre` and the
       basic example imports `FoundryChatClient` from `agent_framework.foundry`,
       so the documented install path was failing with ImportError. Pulling
       agent-framework-foundry into deps makes the advertised entry path
       self-contained.
    
    2. agent-framework-foundry: bump agent-framework-openai lower bound from
       >=1.1.0 to >=1.2.2,<2. Foundry imports private modules from
       agent_framework_openai (`_chat_client.py:22`, `_agent.py:34`), so
       resolvers were free to pair foundry==1.2.2 with older OpenAI versions
       that lack this release's coordinated Responses/history fix. Lockstep the
       floor with the released cohort to prevent mismatched installs.
    
    Both changes pass `validate-dependency-bounds-test` lower + upper at
    their respective packages.
  • Python: Feature/hosted dwf (#5531)
    * Fix declarative Workflow.as_agent() by accepting list[Message] in start executor
    
    The declarative start executor (JoinExecutor) only advertised dict and str
    in its input_types, so WorkflowAgent.__init__ rejected it with
    'Workflow's start executor cannot handle list[Message]'.
    
    Add list[Message] to the JoinExecutor handler annotation and add a
    matching branch in DeclarativeActionExecutor._ensure_state_initialized
    that extracts the last user-message text and falls through to the
    string-input initialization path, so =System.LastMessageText works
    end-to-end via as_agent().
    
    Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
    
    * Populate Conversation.messages from list[Message] trigger
    
    When Workflow.as_agent() is invoked with a list[Message], the start executor now populates Conversation.messages / Conversation.history / System.conversations.{id}.messages with prior turns only (excluding the latest user message), and surfaces the latest user message via Inputs.input and System.LastMessage*. This matches InvokeAzureAgent's contract that the messages binding holds prior turns and the executor itself appends the new user input before invoking, avoiding double-append of the trailing user turn while preserving full history (incl. assistant/system/tool roles and multi-modal content) for downstream actions.
    
    * Coerce Enum values when serializing PowerFx symbols
    
    MessageRole and other str-subclass Enums passed isinstance(v, str) and were forwarded to pythonnet unchanged. pythonnet then raised 'MessageRole value cannot be converted to System.String' for every PowerFx primitive when ConditionGroup/Expr eval walked the symbol table containing Conversation.messages. Reduce Enum members to their underlying value before the primitive check so eval sees plain strings/ints.
    
    * Foundry hosting: pass full conversation history to workflow agents
    
    _handle_inner_workflow only forwarded the latest user turn to WorkflowAgent.run, even though _handle_inner_agent already prepends history fetched from Foundry storage to the messages it sends a regular agent. Declarative workflows reset Conversation.messages on every run (state.initialize), so checkpoint replay alone does not give them prior turns - the host has to pass them in, the same way it does for non-workflow agents. Mirror that contract: fetch context.get_history() and pass [*history, *input_messages] to the workflow agent.
    
    * feat(workflows): support combined message + checkpoint_id for multi-turn continuation
    
    Allow Workflow.run(message=..., checkpoint_id=...) so callers can restore
    prior workflow state from a checkpoint AND deliver a new message to the
    start executor in a single call. The existing reset_context logic
    already preserves shared state when checkpoint_id is set, so this gives
    us 'fresh start executor invocation with prior state intact' - exactly
    what hosted multi-turn declarative workflows need.
    
    - _workflow.py: drop the message+checkpoint_id mutual exclusion and
      update _execute_with_message_or_checkpoint to do both (restore then
      execute) when both are provided.
    - _agent.py: in _run_core's checkpoint branch, also forward
      input_messages so WorkflowAgent.run(messages, checkpoint_id=...) works
      end-to-end. Falls back to the legacy 'restore only' behavior when
      messages are absent.
    - _declarative_base.py: detect continuation in _ensure_state_initialized
      by checking whether DECLARATIVE_STATE_KEY already exists in shared
      state; if so, refresh inputs/LastMessage* and append non-user trigger
      messages instead of calling state.initialize() (which would wipe
      Conversation/Local/System).
    - foundry_hosting/_responses.py: collapse the host's two-call pattern
      (restore-only, then fresh run) into a single combined call now that
      the underlying APIs support it.
    - tests: drop the assertion that combined message+checkpoint_id raises.

    * Pivot: preserve workflow state across run() calls
    
    Replace the prior 'combined message + checkpoint_id in one run()' approach
    with a cleaner default: Workflow.run no longer wipes shared state or runner-
    context messages between calls. Iteration counting and per-run kwargs still
    reset on a fresh-message run; checkpoint and responses runs are continuations
    that preserve everything.
    
    This lets a WorkflowAgent be invoked repeatedly on the same instance and
    maintain multi-turn context (e.g. accumulated Conversation.messages) without
    asking developers to opt in. Hosted-agent multi-turn pattern becomes two
    explicit calls: restore-from-checkpoint (drive to idle), then run-with-message.
    
    Key changes:
    - _workflow.py: drop _state.clear() and reset_for_new_run() from run().
      Reset iteration count and run kwargs on fresh-message runs only.
      Restore 'Cannot provide both message and checkpoint_id' validation.
      Add async guard: fresh-message run with un-drained pending executor
      messages from a prior run is invalid.
    - _runner.py: clear _state before import_state in restore_from_checkpoint
      so restore is authoritative (import_state merges, not replaces).
    - _agent.py: revert checkpoint branch to restore-only (no message forward).
    - _responses.py (foundry_hosting): two-call host pattern - restore checkpoint
      silently, then run with new user input.
    - tests: state-preservation is the new default; rebuild Workflow for clean slate.

    * Fix CI lint and mypy issues from prior pivot commit
    
    - _workflow.py: collapse nested if (SIM102), drop redundant assignment (RET504)
    - _declarative_base.py: remove unused last_user_msg = tail assignment
      whose Message | None type clashed with the prior Message-typed branch

    * Address PR review: fix Inputs.input update and checkpoint storage path
    
    - _declarative_base.py: continuation branch was writing 'Inputs.input' via
      state.set, which routes to the Custom namespace and never updates the
      PowerFx-visible Workflow.Inputs.input. Update state_data['Inputs'] in
      place via get_state_data / set_state_data so =Workflow.Inputs.input and
      =inputs.input see the new turn's user text on continuation.
    - _declarative_base.py: refresh docstring to clarify that on a list[Message]
      trigger, Conversation.messages excludes the current user message at the
      start of the turn (agent executors append it before invoking the inner
      agent).
    - _responses.py: when previous_response_id is supplied (no conversation_id),
      the prior checkpoint lives under <storage>/<previous_response_id> but new
      checkpoints must land under <storage>/<current_response_id> for the next
      turn to find them. Hold onto restore_storage from the get_latest lookup
      and pass it to the restore-only run; pass write_storage (current id) to
      the message-delivery run and to checkpoint cleanup.

    * Fix pyright errors in _declarative_base.py for CI
    
    - Replace state._state.get(...) protected access with new public
      is_initialized() method on DeclarativeWorkflowState (also clearer intent
      for the continuation detection use case).
    - Add narrow pyright ignores for the Any-typed trigger paths that pyright
      cannot fully narrow (the list[Message] isinstance loop and the
      fallback-DefaultTransform branch).

    * Address Copilot review batch: tests + Workflow.reset escape hatch
    
    * Add Workflow.reset() public method as recovery escape hatch when an
      in-flight run aborted (e.g. WorkflowConvergenceException) and the
      workflow is not checkpointed. Update the in-flight messages guard's
      error message to point callers at it.
    
    * Add test_workflow_run_inflight_messages_guard exercising both the
      guard (sync + streaming) and the reset() recovery path.
    * Add test_workflow_reset_rejects_concurrent_runs to lock down the
      in-progress guard on reset.
    
    * Add test_as_agent_continuation_preserves_prior_state covering the
      is_continuation branch in _ensure_state_initialized: stamps a marker
      between calls and asserts it survives, while Inputs.input and
      System.LastMessageText refresh to the new turn.
    
    * Add test_powerfx_safe.py regression tests for the Enum branch in
      _make_powerfx_safe (str-subclass, int-subclass, plain Enum, and
      Enums nested in dict/list).
    
    * Drop redundant @pytest.mark.asyncio on
      test_as_agent_round_trip_with_last_message_text (asyncio_mode='auto').

    * Skip restore-only pre-pass when checkpoint has pending request_info
    
    Address Copilot review on _responses.py: the restore-only checkpoint
    replay populates self._agent.pending_requests for any request_info
    events captured in the checkpoint. The follow-up run(input_messages)
    call would then route through WorkflowAgent._process_pending_requests,
    which expects function-response content and rejects plain text input
    as 'unexpected content while awaiting request info responses'.
    
    Workflows resumed from a checkpoint that was idle-with-pending-requests
    would therefore fail every subsequent plain-text user turn. Inspect the
    loaded checkpoint and skip the pre-pass when its
    pending_request_info_events dict is non-empty. Workflows that don't use
    request_info (the current sample set) are unaffected; workflows that do
    will fall through to a fresh-message run rather than silently corrupting
    the routing state.

    * Loosen azure-ai-agentserver-* pins to major version
    
    The exact-version pins on azure-ai-agentserver-{core,responses,invocations}
    forced foundry-hosting consumers to upgrade in lockstep with every beta
    bump from upstream. Switch to '>=current,<next-major' so we pick up patch
    and feature updates within the same major series without a coordinated
    release.
    
    Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
    
    * Drop Workflow.reset(); checkpointing is the recovery path
    
    The in-flight-messages guard prevented silent misbehavior, but the
    companion Workflow.reset() escape hatch only cleared _messages while
    leaving iteration count, executor-local state, and shared State
    mutations in an indeterminate condition after a mid-run failure. That
    gave a false sense of recovery.
    
    Recovery from a mid-run failure is supported only via checkpoint
    restoration. Keep the guard and reframe its error message accordingly;
    remove reset() and its tests.

    * Address Tao's review on PR 5531
    
    - Rename Workflow._run_workflow_with_tracing parameter
      is_fresh_message_run -> is_continuation (default False, inverted).
      Fresh-message turns reset per-run accounting; continuations
      (checkpoint restores, responses replays) preserve it.
    - Simplify the in-flight-messages guard: _validate_run_params already
      enforces that 'message' is mutually exclusive with 'checkpoint_id'
      and 'responses', so the additional checks were dead code.
    - foundry_hosting _responses: move the restore-only pre-pass above
      emit_created/emit_in_progress; restore is preparation, not run
      progress. Drop the skip-restore gate (state preservation requires
      unconditional restore) and instead clear agent.pending_requests
      after the restore-only call. Collapse over-conditioned check.
    
    Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
    
    * Don't clear pending_requests after restore-only pre-pass
    
    Pending requests in the restored checkpoint represent genuinely
    outstanding HITL requests. The next user input may carry function
    responses (Responses API `function_call_output` items become
    FunctionResultContent / FunctionApprovalResponseContent), which
    `WorkflowAgent._process_pending_requests` correctly extracts and
    matches against the populated `pending_requests`. Clearing them
    after restore would silently drop that state and force the next turn
    to be treated as a fresh input even when the caller is responding to
    the outstanding requests.

  • Python: Fix PowerFx eval crash on non-English system locales by setting CurrentUICulture to en-US (#4408)
    * Fix #4321: Set CurrentUICulture to en-US in PowerFx eval()
    
    On non-English systems, CultureInfo.CurrentUICulture causes PowerFx to
    emit localized error messages. The existing ValueError guard only matches
    English strings ("isn't recognized", "Name isn't valid"), so undefined
    variable errors crash instead of returning None gracefully.
    
    Fix: save and restore CurrentUICulture alongside CurrentCulture before
    calling engine.eval(), ensuring error messages are always in English.

    * Reuse single CultureInfo instance to avoid redundant allocations
    
    Cache CultureInfo("en-US") in a local variable instead of instantiating
    it twice per eval() call, as suggested in PR review.
    
    Fixes #4321

    * Add assertion for CurrentUICulture restoration after eval
    
    Assert that the production code's finally-block correctly restores
    CurrentUICulture to it-IT after eval returns, covering future
    regressions where the culture could leak.
    
    The CultureInfo caching suggestion (comment #2) was already
    implemented in the production code.

  • Python: Add regression tests for Entry JoinExecutor Workflow.Inputs initialization (#4335)
    * Python: Add regression tests for #3948 - Entry JoinExecutor initializes Workflow.Inputs
    
    Add tests verifying that when workflow.run() is called with a dict or string
    input, the Entry node (JoinExecutor with kind: 'Entry') correctly initializes
    Workflow.Inputs via _ensure_state_initialized so that:
    - Expressions like =inputs.age resolve to the correct value
    - Conditions like =Local.age < 13 evaluate based on actual input (not blank/0)
    - String inputs populate both inputs.input and System.LastMessage.Text

    * Fix D420 and RUF070 lint errors across packages
    
    * Revert _workflow.py yield-inside-context-manager changes
    
    Moving yield inside `with _framework_event_origin()` blocks in the
    async generator causes ContextVar token reset failures on Python 3.12
    Windows. The token stays un-reset while the generator is suspended,
    and async generator finalization in a different contextvars.Context
    triggers ValueError, corrupting OpenTelemetry span state and causing
    test_span_creation_and_attributes to see leaked spans.
    
    Keep yields outside the context manager blocks to ensure tokens are
    reset immediately before the generator suspends.

  • Python: [BREAKING] Redesign Python exception hierarchy (#4082)
    * [BREAKING] Redesign Python exception hierarchy
    
    Replace the flat ServiceException family with domain-scoped branches:
    - AgentException (with InvalidAuth, InvalidRequest, InvalidResponse, ContentFilter)
    - ChatClientException (same consistent suberrors)
    - IntegrationException (same + InitializationError)
    - WorkflowException (Runner, Convergence, Checkpoint, Validation, Action, Declarative)
    - ContentError (AdditionItemMismatch)
    - ToolException / ToolExecutionException (unchanged)
    - MiddlewareException / MiddlewareTermination (unchanged)
    
    Key changes:
    - All Service* exceptions removed (ServiceException, ServiceInitializationError, etc.)
    - AgentExecutionException split into AgentInvalidRequest/ResponseException
    - AgentInvocationError removed, split into AgentInvalidRequest/ResponseException
    - Workflow exceptions moved from _workflows/_exceptions.py into main exceptions.py
    - _workflows/__init__.py emptied; main __init__.py imports directly from submodules
    - Purview exceptions re-parented under IntegrationException hierarchy
    - Init validation errors use built-in ValueError/TypeError instead of custom exceptions
    - CODING_STANDARD.md updated with hierarchy design and rationale
    
    Fixes microsoft/agent-framework#3410
    
    Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
    
    * Clarify ToolException vs ToolExecutionException docstrings
    
    ToolException: base class for all tool-related exceptions (preconditions,
    connection/init failures).
    ToolExecutionException: runtime call failures (tool call failed, reconnect
    failed, MCP errors).

    * Fix remaining stale imports from agent_framework._workflows
    
    - azurefunctions: _context.py, _app.py, _serialization.py, test_func_utils.py
      used 'from agent_framework._workflows import X' which broke after
      emptying _workflows/__init__.py; changed to direct submodule imports
    - azure-ai-search: test still referenced ServiceInitializationError;
      updated to ValueError to match production code

  • Python: restructure: Python samples into progressive 01-05 layout (#3862)
    * restructure: Python samples into progressive 01-05 layout
    
    - 01-get-started/: 6 numbered steps (hello agent → hosting)
    - 02-agents/: all agent concept samples (tools, middleware, providers, etc.)
    - 03-workflows/: ALL existing workflow samples preserved as-is
    - 04-hosting/: azure-functions, durabletask, a2a
    - 05-end-to-end/: demos, evaluation, hosted agents
    - Old files moved to _to_delete/ for review
    - Added AGENTS.md with structure documentation
    - autogen-migration/ and semantic-kernel-migration/ preserved at root
    
    * fix: switch to AzureOpenAI Foundry, fix CI failures
    
    - Switch all 01-get-started samples to AzureOpenAIResponsesClient with
      Azure AI Foundry project endpoint (AZURE_AI_PROJECT_ENDPOINT +
      AZURE_OPENAI_RESPONSES_DEPLOYMENT_NAME + AzureCliCredential)
    - Add _to_delete/ and 05-end-to-end/ to pyrightconfig.samples.json excludes
    - Fix test paths in packages/ that referenced old getting_started/ dirs:
      durabletask conftest + streaming test, azurefunctions conftest,
      devui conftest + capture_messages + openai_sdk_integration
    - Fix workflow_as_agent_human_in_the_loop.py import (sibling import)
    - Update hosting READMEs and tool comment paths
    - Replace root README.md with new structure overview
    - Update AGENTS.md to document Azure OpenAI Foundry as default provider
    
    * cleanup: remove _to_delete folder, copy resource files to active dirs
    
    All files in _to_delete/ were either:
    - Exact duplicates of files in the new structure (240 files)
    - Same file with only comment path updates (100 files)
    - One import-fix diff (workflow_as_agent_human_in_the_loop.py)
    - One superseded minimal_sample.py
    
    Resource files (sample.pdf, countries.json, employees.pdf, weather.json)
    copied to 02-agents/sample_assets/ and 02-agents/resources/ since active
    samples reference them.
    
    * fix: address PR review comments, centralize resources, remove root duplicates
    
    - Fix type annotation in 04_memory.py (string union -> proper types)
    - Fix old sample paths in observability files
    - Fix grammar/spelling in observability samples
    - Move sample_assets/ and resources/ to shared/ folder
    - Remove 8 duplicate observability files from 02-agents root
    - Update resource path references in multimodal_input and provider samples
    
    * fix: update broken links from old getting_started paths to new structure
    
    - Update relative paths in READMEs: getting_started/ → 01-get-started/,
      02-agents/, 03-workflows/, 04-hosting/, 05-end-to-end/
    - Fix absolute GitHub URLs in package READMEs
    - Fix broken link in ollama package README
    
    * fix: convert absolute GitHub URLs to relative paths for link checker
    
    Absolute URLs to python/samples/ on main branch 404 until PR merges.
    Converted to relative paths that linkspector can verify locally.
    
    * fix: update link for handoff sample moved to orchestrations/
    
    * fix: update chatkit-integration README path from demos/ to 05-end-to-end/

  • Python: [BREAKING] Simplify API: ChatAgent -> Agent, ChatMessage -> Message (#3747)
    * [BREAKING] Rename ChatAgent -> Agent, ChatMessage -> Message, ChatClientProtocol -> SupportsChatGetResponse
    
    Simplify the public API by removing redundant 'Chat' prefix from core types:
    - ChatAgent -> Agent
    - RawChatAgent -> RawAgent
    - ChatMessage -> Message
    - ChatClientProtocol -> SupportsChatGetResponse
    
    Also renamed internal WorkflowMessage (was Message in _runner_context) to avoid collision.
    
    No backward compatibility aliases - this is a clean breaking change.
