    * Fix Magentic to share agent replies across team
    
    The per-round instruction was sent untargeted (fan-out delivered it to
    every participant) and replies were never relayed, so a later speaker saw
    the prior speaker's instruction but not its response - inverted from
    GroupChatHost and the Python reference.
    
    - Target the instruction at the selected speaker only.
    - Broadcast each reply to the other participants (buffered, no TurnToken),
      excluding the responder via _currentSpeakerExecutorId, mirroring
      GroupChatHost.
    - Persist _currentSpeakerExecutorId across checkpoints.
    - Add a regression test.
    
    * Address review feedback: null-guard, explicit checkpoint key, drop vacuous assertion
    
    * Address review feedback: centralize checkpoint keys, clear current speaker
    
    - Move CurrentSpeakerStateKey into MagenticConstants as
      nameof(CurrentSpeakerStateKey)
    - Clear _currentSpeakerExecutorId in ResetAndReplanAsync and
      PrepareFinalAnswerAsync so a checkpoint taken in those windows does not
      persist a stale speaker
    - Add UTF-8 BOM to RecordingEchoAgent.cs to satisfy the format check.
  • .NET: Forward Magentic participant replies to manager (#6156)
    MagenticOrchestrator.TakeTurnAsync dropped the `messages` parameter
    on subsequent turns, so participant replies never reached the manager's
    ChatHistory. The manager kept re-dispatching the same speaker every
    round until MaxRounds.
    
    Append the incoming messages to taskContext.ChatHistory before running
    the coordination round (matches Python's _handle_response).
    
    Adds RecordingReplayAgent + regression test that asserts the worker's
    reply reaches round-2's progress-ledger call.

  • .NET: Workflow Outputs Overhaul: Support Tagging, Filtering Agent Outputs (#6045)
    * test: reshuffle .NET Workflow tests in preparation for Outputs overhaul
    
    Phase 1 of the .NET Workflows outputs overhaul (see
    working/implementation-plan.md). Pure moves/renames in
    dotnet/tests/Microsoft.Agents.AI.Workflows.UnitTests; no production code
    changes, no new test cases. The split keeps each orchestration mode in
    its own source file so the upcoming tag-aware and orchestration-default
    test additions land on clean diffs.
    
    Renames:
    * WorkflowBuilderSmokeTests.cs -> WorkflowBuilderTests.cs (with class
      rename to match). The scope is no longer "smoke"-only once subsequent
      phases add tag-aware builder tests.
    * InputWaiterAndOutputFilterTests.cs -> InputWaiterTests.cs +
      OutputFilterTests.cs. The file already declared the two test classes
      separately; this split simply gives each its own file so the
      output-filter cases have a dedicated home for tag-aware additions.
    
    Split of AgentWorkflowBuilderTests.cs:
    * AgentWorkflowBuilderTests.cs is now the outer
      `public static partial class AgentWorkflowBuilderTests` holding the
      shared test helpers (DoubleEchoAgent + session + WithBarrier variant,
      WorkflowRunResult, RunWorkflow* methods) bumped from `private` to
      `internal` so the new top-level GroupChatWorkflowBuilderTests in the
      same assembly can reach them.
    * AgentWorkflowBuilder.SequentialTests.cs (nested SequentialTests):
      BuildSequential_InvalidArguments_Throws,
      BuildSequential_AgentsRunInOrderAsync.
    * AgentWorkflowBuilder.ConcurrentTests.cs (nested ConcurrentTests):
      BuildConcurrent_InvalidArguments_Throws,
      BuildConcurrent_AgentsRunInParallelAsync.
    
    Sequential and Concurrent are kept as nested classes because they're
    modes of the same `AgentWorkflowBuilder` static factory and do not
    produce dedicated builder types.
    
    New file:
    * GroupChatWorkflowBuilderTests.cs (top-level): the existing
      BuildGroupChat_* and GroupChatManager_* cases moved out of the old
      AgentWorkflowBuilderTests file. They exercise the
      `GroupChatWorkflowBuilder` type (returned by
      `AgentWorkflowBuilder.CreateGroupChatBuilderWith`), so a dedicated
      top-level test class - matching the convention reserved by the plan
      for HandoffWorkflowBuilderTests / MagenticWorkflowBuilderTests - is
      the right home. Cross-class helper references qualify with
      `AgentWorkflowBuilderTests.DoubleEchoAgent` and
      `AgentWorkflowBuilderTests.RunWorkflowAsync`.
    
    The outer partial class is `static` (and nested classes carry the
    instance test methods) because the outer holds only static helpers;
    this satisfies CA1052 without suppressions and is invisible to xUnit
    discovery, which finds tests on the nested classes as
    `AgentWorkflowBuilderTests.SequentialTests.*` etc.
    
    Validation: `dotnet build` clean on both target frameworks; all 547
    tests in Microsoft.Agents.AI.Workflows.UnitTests pass on net10.0.

    * feat: introduce OutputTag, Futures, and tag-aware WorkflowBuilder API
    
    Phase 2 of the .NET Workflows outputs overhaul. Additive code change
    only - no observable runtime behavior change. The runner still uses the
    legacy bypass for AgentResponse / AgentResponseUpdate payloads, and the
    new `Futures.EnableAgentResponseOutputTaggingAndFiltering` flag defaults
    to false. Phase 3 will wire the flag into the runner; this commit only
    introduces the types and the builder API.
    
    New public surface:
    * `OutputTag` (readonly struct): wraps a string Value with ordinal
      equality (IEquatable, GetHashCode, == / !=) so it can participate as a
      HashSet element. Internal ctor closes the set. One public singleton:
      `OutputTag.Intermediate`. Terminal / regular outputs carry no tag
      (empty Tags set). JSON-serialized as a bare string via
      [JsonConverter(typeof(OutputTagJsonConverter))], with the converter
      rehydrating to the well-known singleton on read.
    * `Futures` (static class): hosts opt-in pre-GA behavior switches.
      First flag is `EnableAgentResponseOutputTaggingAndFiltering`; XML doc
      captures the v2.0.0 obsoletion / v3.0.0 removal lifecycle.
    * `WorkflowOutputEvent.Tags`: `HashSet<OutputTag>` exposed directly
      (concrete collection, matches the JSON-serialization convention used
      for `WorkflowInfo.OutputExecutorIds`). Never null; empty for legacy /
      terminal events. New ctors take a single `OutputTag` or
      `IEnumerable<OutputTag>?`; the existing (data, executorId) ctor
      remains and produces an untagged event. `HasTag(OutputTag)` helper.
      `AgentResponseEvent` and `AgentResponseUpdateEvent` gain matching
      tag-accepting ctors forwarding to the base.
    * `WorkflowOutputEventExtensions.IsIntermediate(this WorkflowOutputEvent)`:
      extension method returning `evt.HasTag(OutputTag.Intermediate)`. The
      preferred way to ask "is this an intermediate output?" without
      reaching into the Tags set.
    * `WorkflowBuilder.WithOutputFrom(IEnumerable<ExecutorBinding>, OutputTag)`
      and `WorkflowBuilder.WithOutputFrom(ExecutorBinding, OutputTag)`:
      forward-looking tagged overloads. The IEnumerable form is the primary
      tagged surface; the single-executor form is a convenience for the
      common one-executor case. Currently usable for the
      `OutputTag.Intermediate` singleton; will become the primary surface
      once the `OutputTag` constructor is opened to user-defined tags in
      a future release. Callers in this release should prefer the
      intent-specific `WithIntermediateOutputFrom` extension for the
      intermediate case. Tags accumulate across repeated calls; same tag
      repeated dedupes via the HashSet.
    * `WorkflowBuilderExtensions.WithIntermediateOutputFrom(this WorkflowBuilder, IEnumerable<ExecutorBinding>)`:
      helper that forwards to `WithOutputFrom(executors, OutputTag.Intermediate)`.
      Takes an IEnumerable (matching the tagged WithOutputFrom shape) -
      callers pass collection literals: `builder.WithIntermediateOutputFrom([a, b])`.
      XML doc remarks call out the Futures-flag interaction and the
      AIAgent-payload forwarding contract.
    
    Internal shape changes:
    * `WorkflowBuilder._outputExecutors`: HashSet<string> -> Dictionary<
      string, HashSet<OutputTag>>. The value set is empty for executors
      designated only via the untagged WithOutputFrom; contains Intermediate
      (and possibly future tags) otherwise.
    * `Workflow.OutputExecutors`: HashSet<string> -> Dictionary<string,
      HashSet<OutputTag>>.
    * `OutputFilter.CanOutput`: `Contains(id)` -> `ContainsKey(id)`.
    * `WorkflowInfo.OutputExecutorIds`: HashSet<string> -> Dictionary<
      string, HashSet<OutputTag>>, with a custom JsonConverter that reads
      both the new map shape (`{id: ["intermediate", ...]}`) and the legacy
      array shape (`[id1, id2]`, where each id is treated as an untagged
      output). Always writes the map shape. IsMatch updated to compare
      per-id tag sets.
    
    Tests landing in this commit (per the test-with-feature principle):
    * `OutputTagTests.cs` (6 tests): KnownValues, EqualityIsOrdinalOnValue,
      DefaultStructValueIsDistinct (default(OutputTag) does not collide
      with the Intermediate singleton in a HashSet),
      GetHashCodeMatchesEquals, JsonConverter_RoundtripsValueAsString,
      ConstructorIsInternal (reflection-based assertion that the (string)
      ctor is `internal`).
    * `WorkflowBuilderTests.cs` adds 7 new tests pinning the builder
      API contract: RegistersWithEmptyTagSet, AddsIntermediateTag,
      MultipleExecutorsAllUntagged, ThenIntermediate_AccumulatesTags,
      RepeatedDedupes, OnlyRegistersWithoutPriorWithOutputFrom,
      TracksExecutorBinding.
    * `BackwardsCompatibility/JsonCheckpointSerializationTests.cs`
      (new folder + file, 5 tests): event-level ctor contract tests
      (single-tag, no-tag, multi-tag — the last with a custom tag);
      IsIntermediate() asserted; load-bearing JSON BC tests for
      `WorkflowInfo.OutputExecutorIds` -
      `WorkflowOutputExecutorsReadsLegacyArrayShape` (legacy ids map to
      empty tag sets) and `WorkflowOutputExecutorsWritesMapShape`.
    
    The plan's three JSON round-trip tests for `WorkflowOutputEvent.Tags`
    were dropped: `WorkflowEvent` is not currently a serialized checkpoint
    shape (see the comment in WorkflowsJsonUtilities.cs about events not
    being persisted), so there is no real back-compat surface to pin
    through JSON. They are substituted with in-process ctor/property
    round-trip tests that exercise the `Tags` / `HasTag` / `IsIntermediate`
    contract.
    
    Validation: full `Microsoft.Agents.AI.Workflows.UnitTests` suite runs
    green on net10.0 (565 passing, 0 failing). Core library builds clean
    on net472, netstandard2.0, net8.0, net9.0, and net10.0. Test project
    builds clean on net472 + net10.0.

    * feat: route AgentResponse(Update) through the output filter under a Futures flag
    
    `InProcessRunnerContext.YieldOutputAsync` historically special-cased AgentResponse and
    AgentResponseUpdate payloads: it built the typed event subclass and emitted it directly,
    bypassing the output filter. Rewrites the method so that:
    
    - When `Futures.EnableAgentResponseOutputTaggingAndFiltering` is `false` (the current
      default), AgentResponse(Update) keep the legacy bypass — emitted as
      AgentResponseEvent / AgentResponseUpdateEvent with no tags. Existing callers see no
      behavior change.
    - When the flag is `true`, AIAgent payloads flow through the output filter just like
      every other payload type: undesignated sources are dropped, and the emitted event
      carries the source's tag set (empty for terminal `WithOutputFrom`, `{Intermediate}`
      for `WithIntermediateOutputFrom`, the set union when both designations apply).
    
    Non-AIAgent (POCO) outputs also now carry the source's tag set on the emitted
    WorkflowOutputEvent unconditionally — additive, since no existing assertion inspected
    Tags. Subclass events (`AgentResponseEvent` / `AgentResponseUpdateEvent`) continue to
    be emitted under both modes so `switch (evt) { case AgentResponseEvent: ... }`
    consumer code keeps matching.
    
    Adds `OutputFilter.TryGetTags` as the tag-aware lookup used by the runner.
    `OutputFilter.CanOutput` is kept (still used by the existing sync tests in
    `OutputFilterTests.cs`).
    
    Tests
    -----
    - `Futures/Futures.AgentResponseOutputFilteringAndTaggingTests.cs` (new): the F1–F13
      matrix from the plan, covering every combination of `(flag on/off) × (designation)
      × (payload shape)`. Uses a `FuturesScope` IDisposable + a `FuturesSerial` xUnit
      collection (DisableParallelization = true) to keep the process-global flag from
      leaking across parallel tests.
    - `OutputFilterTests.cs`: four new `Test_OutputFilter_…` cases for the `TryGetTags`
      surface (empty-tag-set for terminal designation, `{Intermediate}` for intermediate
      designation, union for accumulated designation, `false` for unregistered).
    
    582/582 unit tests pass on net10.0 (565 baseline + 17 new).

    * feat: tag-aware defaults and designation API on orchestration builders
    
    Aligns the .NET orchestration builders with Python's output / intermediate-output
    distinction. Each builder either applies a Python-aligned default designation set or
    replays the user's explicit `WithOutputFrom` / `WithIntermediateOutputFrom` calls,
    never both.
    
    Static `AgentWorkflowBuilder.BuildSequential` / `BuildConcurrent` apply defaults
    unconditionally (no user-facing fluent surface to take control through):
    
    - Sequential: terminal `end` + every agent designated intermediate.
    - Concurrent: terminal `end` + every agent and per-agent accumulator designated
      intermediate.
    
    The three fluent instance builders memoize agent-typed designation calls in a
    `Dictionary<AIAgent, HashSet<OutputTag>>` (empty set = terminal-only, non-empty =
    intermediate tag(s)) so repeated calls dedupe naturally. They replay the entries
    at `Build()` time, suppressing defaults when any call has been made:
    
    - `HandoffWorkflowBuilder` / `HandoffWorkflowBuilderCore<TBuilder>` (also picked up
      by the obsolete `HandoffsWorkflowBuilder` via inheritance).
      Default: terminal `HandoffEnd` + every handoff agent intermediate.
      (Bug fix: legacy code relied on `WithOutputFrom(end)` to bind `HandoffEnd`. The
      new explicit-designation path bypasses that, so `Build()` now calls
      `BindExecutor(end)` unconditionally to keep validation happy.)
    - `GroupChatWorkflowBuilder` — default: terminal host + every participant intermediate.
    - `MagenticWorkflowBuilder` — default: terminal orchestrator + every team member
      intermediate.
    
    Designating a non-participant agent throws `InvalidOperationException`.
    
    The bare `WorkflowBuilder` default is unchanged — only the orchestration-style
    builders gain implicit defaults, matching the plan's non-goal.
    
    Tests
    -----
    - `AgentWorkflowBuilder.SequentialTests` / `.ConcurrentTests`: one default-spec
      assertion each.
    - `GroupChatWorkflowBuilderTests`: defaults-match-spec, explicit-replaces-defaults,
      non-participant throws.
    - `HandoffWorkflowBuilderTests` (new file): same three.
    - `MagenticWorkflowBuilderTests` (new file): same three.
    
    593/593 unit tests pass on net10.0 (582 baseline + 11 new).

    * feat: WorkflowHostAgent forwards AgentResponseEvent unconditionally under Futures-on
    
    Aligns the .NET Workflow-as-Agent surface with Python `as_agent`. Under
    `Futures.EnableAgentResponseOutputTaggingAndFiltering = true`,
    `WorkflowSession.InvokeStageAsync` now forwards `AgentResponseEvent`
    unconditionally — joining `AgentResponseUpdateEvent` in ignoring the host's
    `includeWorkflowOutputsInResponse` switch. That switch keeps governing the
    generic `WorkflowOutputEvent` path for non-AIAgent payloads, where it is
    further short-circuited by an `IsIntermediate()` check (tagged intermediate
    outputs always surface).
    
    Under Futures-off the legacy asymmetry is preserved: `AgentResponseUpdateEvent`
    always forwarded, `AgentResponseEvent` gated by `includeWorkflowOutputsInResponse`.
    
    Back-compat: with `Futures.EnableAgentResponseOutputTaggingAndFiltering` left at
    its default `false`, observable behavior is identical to before.
    
    `Futures` documentation gains a remark explaining the `Workflow.AsAIAgent()`
    interaction in both flag states.
    
    Runner fix
    ----------
    `InProcessRunnerContext.YieldOutputAsync` now skips `Executor.CanOutput` for
    AgentResponse-shaped payloads under both Futures branches. `AIAgentHostExecutor`
    doesn't declare AgentResponse(Update) in its `Yields` set, so the historical
    legacy bypass had silently skipped the check; Phase 3's Futures-on path was
    running it and would reject AIAgent payloads. AIAgent-shaped payloads are now
    always a valid output shape, matching the legacy bypass semantics.
    
    Phase 4 follow-on
    -----------------
    Switched the three orchestration-builder designation-replay loops to iterate
    `Dictionary.Keys` with a value lookup instead of constructing/destructuring
    `KeyValuePair<,>`. Cleaner shape and avoids the netstandard2.0 / net472
    `KeyValuePair<,>.Deconstruct` unavailability that surfaced when this branch
    multi-TFM-built.
    
    Tests
    -----
    `WorkflowHostSmokeTests.IntermediateForwarding` (new nested class, 6 tests):
    - intermediate AgentResponse forwarded past the include-outputs gate (Futures on)
    - terminal AgentResponse forwarded unconditionally (Futures on)
    - terminal AgentResponse gated by include flag (Futures off, legacy)
    - undesignated AIAgent executor emits no AgentResponseEvent under Futures-on
    - legacy bypass still emits AgentResponseEvent under Futures-off
    - intermediate tag is observable via `update.RawRepresentation`
    
    The class joins the `FuturesSerial` xUnit collection so the process-global flag
    is serialized against other Futures-toggling tests.
    
    599/599 unit tests pass on net10.0 (593 baseline + 6 new).

    * feat: SequentialWorkflowBuilder and ConcurrentWorkflowBuilder, OrchestrationBuilderBase
    
    Promotes the Sequential and Concurrent orchestration shapes to first-class fluent
    builder classes, matching Handoff / GroupChat / Magentic. Users can call
    `WithOutputFrom(agents)` / `WithIntermediateOutputFrom(agents)` to control which
    agents are designated output / intermediate sources; when no designation call is
    made, the Python-aligned defaults apply (terminal aggregator output + every agent
    intermediate; Concurrent also tags per-agent accumulators).
    
    `AgentWorkflowBuilder.BuildSequential(...)` and `BuildConcurrent(...)` are kept
    and now delegate to the new builders; observable behavior unchanged. Five static
    factories now mirror each other:
    
    - `AgentWorkflowBuilder.CreateSequentialBuilderWith(params IEnumerable<AIAgent>)`
    - `AgentWorkflowBuilder.CreateConcurrentBuilderWith(params IEnumerable<AIAgent>)`
    - `AgentWorkflowBuilder.CreateHandoffBuilderWith(AIAgent)`        (already existed)
    - `AgentWorkflowBuilder.CreateGroupChatBuilderWith(Func<...>)`    (already existed)
    - `AgentWorkflowBuilder.CreateMagenticBuilderWith(AIAgent)`       (new)
    
    OrchestrationBuilderBase
    ------------------------
    New abstract `OrchestrationBuilderBase<TBuilder>` unifies the shared fluent
    surface across all five orchestration builders: `WithName`, `WithDescription`,
    `WithOutputFrom`, `WithIntermediateOutputFrom`, and the
    `ApplyOutputDesignations(builder, agentMap, kind, applyDefaults)` helper that
    either replays the user's designations or invokes the orchestration-specific
    defaults.
    
    Removes ~150 LOC of duplicated designation-management code from the four
    non-Handoff builders, plus the equivalent from `HandoffWorkflowBuilderCore`.
    
    Tests
    -----
    - New `SequentialWorkflowBuilderTests.cs` / `ConcurrentWorkflowBuilderTests.cs`
      (replace the old `AgentWorkflowBuilder.{Sequential,Concurrent}Tests.cs`
      nested-class files). Method names normalized to
      `Test_<BuilderType>_<Scenario>[Async]`.
    - Shared helpers (`DoubleEchoAgent`, `DoubleEchoAgentWithBarrier`,
      `WorkflowRunResult`, `RunWorkflow*`) moved from the old
      `AgentWorkflowBuilderTests` partial class into a new
      `OrchestrationTestHelpers` static class in `OrchestrationTestHelpers.cs`.
      Downstream test files (Group Chat, Handoff, Sequential, Concurrent) updated
      to qualify with `OrchestrationTestHelpers.*`.
    - A new `AgentWorkflowBuilderTests.cs` covers the static surface directly:
      `BuildSequential` / `BuildConcurrent` invariants and aggregator wiring, plus
      null-rejection + round-trip checks for every `Create*BuilderWith` factory.
    - New AsAgent intermediate-suppression tests on a nested `AsAgentForwarding`
      class for each of Sequential and Concurrent: build with only the terminal
      agent designated via `WithOutputFrom`, run via `AsAIAgent(...)`, assert via
      `AgentResponseUpdate.AuthorName` that intermediate agents do not surface.
      Both join the `FuturesSerial` collection.
    - New `Test_<Builder>_WithDescriptionPropagatesToWorkflow` smoke tests on
      Sequential and Concurrent (newly available via the base class).
    
    625/625 unit tests pass on net10.0.

    * .NET: feat(evals): add ground_truth/expected_output support for workflow eval
    
    Brings .NET to parity with Python PR #5234 for issue #5135:
    
    - Add expectedOutput parameter to Run.EvaluateAsync (workflow) and stamp on the overall EvalItem.ExpectedOutput.
    - Map EvalItem.ExpectedOutput -> ground_truth in the Foundry JSONL payload, item_schema, and data_mapping for similarity.
    - Add GroundTruthEvaluators set (currently builtin.similarity) and a FindMissingGroundTruthEvaluators helper.
    - Fail fast with InvalidOperationException when a ground-truth evaluator is selected but no item provides an ExpectedOutput, instead of surfacing a remote provider error.
    - Add tests in FoundryEvalConverterTests and WorkflowEvaluationTests.
    - Add Evaluation_WorkflowExpectedOutputs sample (workflow + Foundry similarity).
    
    Fixes microsoft/agent-framework#5135 (.NET side).

    * Sample: disable per-agent breakdown when using reference-based evaluator
    
    Per-agent EvalItems are intentionally left without ExpectedOutput, so the new fail-fast validation in FoundryEvals would throw when Similarity is invoked for per-agent items. Pass includePerAgent: false in the workflow + similarity sample, and document this gotcha in the EvaluateAsync XML doc.

    * Fix BuildOverallItem: fall back to last ExecutorCompletedEvent
    
    AgentResponseEvent is only emitted when AIAgentHostOptions.EmitAgentResponseEvents is enabled, which is not the default for WorkflowBuilder(agent).AddEdge(...). When it is absent, fall back to the last non-internal ExecutorCompletedEvent whose Data is an AgentResponse / ChatMessage / string so the overall EvalItem (and any expectedOutput) is produced. Without this, samples wired up the standard way returned 0 evaluation items.
    
    Update test to cover the fallback path.

    * Sample: enable EmitAgentResponseEvents; eval throws clear error when no overall response found
    
    Root cause of '0 results': AIAgentHostExecutor only emits AgentResponseEvent when AIAgentHostOptions.EmitAgentResponseEvents is true (default false). For ordinary AIAgent executors the runtime's ExecutorCompletedEvent.Data is null, so the prior fallback couldn't find a final response either.
    
    Sample now builds executors with EmitAgentResponseEvents=true via BindAsExecutor(hostOptions). EvaluateAsync now throws InvalidOperationException with a remediation hint when the user supplies expectedOutput but no overall final response can be located, instead of silently returning 0/0.

    * Guard against null sample/error/usage/datasource_item in ParseDetailedItem
    
    Foundry eval responses can have these properties present with JSON null
    or non-object values, which caused JsonElement.TryGetProperty to throw
    'requires Object, has Null'. Check ValueKind == Object before drilling in.

    * Address PR review: reorder expectedOutput, tighten ground-truth check, add fail-fast test
    
    * WorkflowEvaluationExtensions.EvaluateAsync: move 'expectedOutput' to
      after 'splitter' so the original positional contract of (splitter,
      cancellationToken) is preserved for existing callers.
    * FoundryEvals: require ALL items to carry ExpectedOutput when a
      ground-truth evaluator is selected (e.g. similarity), not just any.
      Reference-based evaluators score per-item, so a single missing GT
      would still surface as a provider-side validation error. Updated
      fail-fast message accordingly.
    * WorkflowEvaluationTests: add EvaluateAsync_WithExpectedOutputButNoFinalResponse_ThrowsAsync
      to verify the InvalidOperationException is thrown (and that the
      message mentions EmitAgentResponseEvents).
    
    Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
    
    * Fail-fast on missing overall item regardless of expectedOutput; harden BuildOverallItem default
    
    * EvaluateAsync now throws InvalidOperationException whenever 'includeOverall'
      is requested but BuildOverallItem cannot produce an item, instead of only
      when 'expectedOutput' is supplied. Same misconfiguration (agents not bound
      with EmitAgentResponseEvents) used to silently return empty results — now
      it surfaces a clear, actionable error in both cases.
    * BuildOverallItem switch default now throws instead of returning null. The
      preceding for-loop already constrains Data to AgentResponse/ChatMessage/
      string, so reaching default would indicate a contract drift; throw to make
      the bug visible.
    * Test renamed and broadened to verify the throw fires without expectedOutput.

    * test: Split out Handoff Orchestration tests
    
    * fix: Synthesized Handoff FunctionResult is never sent to agent
    
    When we receive a handoff request from the agent, we need to service it outside of the Agent Loop to terminate the loop. What this means is that we take ownership of terminating the call by feeding the result back into the agent on a subsequent invocation.
    
    When we refactored Handoff to support HITL and make use of AgentSession, we inadvertantly removed this step, causing subsequent invocations to the Handoff agent to fail (first works, but breaks the state).
    
    The fix is to be more precise about the agent's bookmark when concatenating the result of agent invocation to the shared conversation history.

  • fix: Duplicate CallIds cause Handoff Message Filtering to fail (#5359)
    Some providers, e.g. Gemini, do not use the CallId mechanism to disambiguate simultaneous function calls. This can result in message lists containing multiple turn to fail to filter properly.
    
    The fix is to take advantage of the expectation that Handoff Orchestration is a "single-speaker" flow, which only has a single active AIAgent per "turn" and an agent's turn is not finished until all outstanding function calls are finished.
    
    This allows us to expect that any ambiguous-CallId FunctionCallContent are either in separate turns or will have had a response before the next issued call with the same Id.

    * fix: Add session support for Handoff-hosted Agents
    
    In order to better support using `Workflows` hosted as `AIAgents` inside of Handoff workflows, we need to make proper use of AgentSession. This causes potential issues around checkpointing and making sure that we properly compute only the new incoming messages for each agent invocation.
    
    * fix: AgentSession checkpointing using AIAgent's Serialize/Deserialize methods
    
    We cannot rely on implicit serialization through `HandoffHostState` because we are missing type information.

    - FoundryEvals: cache evalId per schema shape (hasContext, hasTools) so
      subsequent EvaluateAsync calls create runs under the same eval definition.
    - MeaiEvaluatorAdapter: code already correctly passes queryMessages (not full
      conversation) to IEvaluator — no change needed, verified by inspection.
    - Add tests: AgentResponse full messages preservation, unknown object
      ToString() fallback for ExtractAgentData.

    for the OpenAI Evals API wire format. The OpenAI .NET SDK (2.9.1) only
    provides protocol-level methods with BinaryContent/ClientResult — no
    typed request models. These internal models replace scattered dictionary
    literals with [JsonPropertyName]-annotated classes, giving:
    
    - Compile-time safety (typos become build errors)
    - Single point of change when the API evolves
    - IntelliSense discoverability
    - Cleaner serialization via JsonPolymorphic for content items
    
    Models: WireContentItem hierarchy (text, image, tool_call, tool_result),
    WireMessage, WireEvalItemPayload, WireTestingCriterion, WireItemSchema,
    WireCreateEvalRequest, WireCreateRunRequest, and data source variants.

    RAPI samples should not reference FoundryAgent directly. Restored
    original sample code with only ChatClientAgent -> AIAgent type change
    to accommodate the AsAIAgent return type.

    * Convert versioned-pattern samples to pure RAPI
    
    Step09, Step13, Step17, Step22 were using CreateAgentVersionAsync +
    PromptAgentDefinition which is the versioned pattern. Converted to
    use AsAIAgent(model, instructions, tools) which is the RAPI path.

    Because the tracker was instance-shared between the start and end executors, it would be shared between all sessions, resulting in incorrect behaviour.
    
    The corect way to do this is to keep the data in a shared executor scope, which is per-session.

    The `sessionId`, an optional parameter when starting a new session when

    support whatever ids are needed by other systems, but can result in
    errors when an OS special or forbidden character is included.

    * .NET: Fixing issue where OpenTelemetry span is never exported in .NET in-process workflow execution (#4196)
    
    * 1. Add reproduction test for issue #4155: workflow.run Activity never stopped in streaming OffThread path
    
    The WorkflowRunActivity_IsStopped_Streaming_OffThread test demonstrates that
    the workflow.run OpenTelemetry Activity created in StreamingRunEventStream.RunLoopAsync
    is started but never stopped when using the OffThread/Default streaming execution.
    The background run loop keeps running after event consumption completes, so the
    using Activity? declaration never disposes until explicit StopAsync() is called.

    2. Fix workflow.run Activity never stopped in streaming OffThread execution (#4155)
    
    The workflow.run OpenTelemetry Activity in StreamingRunEventStream.RunLoopAsync
    was scoped to the method lifetime via 'using'. Since the run loop only exits on
    cancellation, the Activity was never stopped/exported until explicit disposal.
    
    Fix: Remove 'using' and explicitly dispose the Activity when the workflow reaches
    Idle status (all supersteps complete). A safety-net disposal in the finally block
    handles cancellation and error paths.
    
    Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
    
    * Add root-level workflow.session activity spanning run loop lifetime\n\nImplements two-level telemetry hierarchy per PR feedback from lokitoth:\n- workflow.session: spans the entire run loop / stream lifetime\n- workflow_invoke: per input-to-halt cycle, nested within the session\n\nThis ensures the session activity stays open across multiple turns,\nwhile individual run activities are created and disposed per cycle.\n\nAlso fixes linkedSource CancellationTokenSource disposal leak in\nStreamingRunEventStream (added using declaration)."
    
    * Address Copilot review: fix Activity/CTS disposal, rename activity, add error tag\n\n1. LockstepRunEventStream: Remove 'using' from Activity in async iterator\n   and manually dispose in finally block (fixes #4155 pattern). Also dispose\n   linkedSource CTS in finally to prevent leak.\n2. Tags.cs: Add ErrorMessage (\"error.message\") tag for runtime errors,\n   distinct from BuildErrorMessage (\"build.error.message\").\n3. ActivityNames: Rename WorkflowRun from \"workflow_invoke\" to \"workflow.run\"\n   for cross-language consistency.\n4. WorkflowTelemetryContext: Fix XML doc to say \"outer/parent span\" instead\n   of \"root-level span\".\n5. ObservabilityTests: Assert WorkflowSession absence when DisableWorkflowRun\n   is true.\n6. WorkflowRunActivityStopTests: Fix streaming test race by disposing\n   StreamingRun before asserting activities are stopped.\n7. StreamingRunEventStream/LockstepRunEventStream: Use Tags.ErrorMessage\n   instead of Tags.BuildErrorMessage for runtime error events."
    
    * Review fixes: revert workflow_invoke rename, use 'using' for linkedSource, move SessionStarted earlier\n\n- Revert ActivityNames.WorkflowRun back to \"workflow_invoke\" (OTEL semantic convention contract)\n- Use 'using' declaration for linkedSource CTS in LockstepRunEventStream (no timing sensitivity)\n- Move SessionStarted event before WaitForInputAsync in StreamingRunEventStream to match Lockstep behavior"
    
    * Improve naming and comments in WorkflowRunActivityStopTests"
    
    * Prevent session Activity.Current leak in lockstep mode, add nesting test
    
    Save and restore Activity.Current in LockstepRunEventStream.Start() so the
    session activity doesn't leak into caller code via AsyncLocal. Re-establish
    Activity.Current = sessionActivity before creating the run activity in
    TakeEventStreamAsync to preserve parent-child nesting.
    
    Add test verifying app activities after RunAsync are not parented under the
    session, and that the workflow_invoke activity nests under the session."
    
    * Fix stale XML doc: WorkflowRun -> WorkflowInvoke in ObservabilityTests

  • .NET: Skip flacky UT + (Attempt) Merge Gatekeeper fix (#4456)

    (MSDO), not by any workflow in this repo, and their transient failures
    should not block merges.

    * Fix flaky test: prevent spurious workflow_invoke Activity on timeout wake-up
    
    The StreamingRunEventStream run loop uses a 1-second timeout on
    WaitForInputAsync. When the timeout fires before the consumer calls
    StopAsync, the loop would create a spurious workflow_invoke Activity
    even though no actual input was provided. This caused the
    WorkflowRunActivity_IsStopped_Streaming_OffThread_MultiTurnAsync test
    to intermittently fail (expecting 2 activities but finding 3).
    
    Fix: guard the loop body with a HasUnprocessedMessages check. On
    timeout wake-ups with no work, the loop waits again without creating
    an activity or changing the run status.

    * Fix epoch race condition causing unit tests to hang on net10.0 and net472
    
    The HasUnprocessedMessages guard (previous commit) correctly prevents
    spurious workflow_invoke Activity creation on timeout wake-ups, but
    exposed a latent race in the epoch-based signal filtering.
    
    The race: when the run loop processes messages quickly and calls
    Interlocked.Increment(ref _completionEpoch) before the consumer calls
    TakeEventStreamAsync, the consumer reads the already-incremented epoch
    and sets myEpoch = epoch + 1. This causes the consumer to skip the
    valid InternalHaltSignal (its epoch < myEpoch) and block forever
    waiting for a signal that will never arrive (since the guard prevents
    spurious signal generation).
    
    Fix: read _completionEpoch without +1. The +1 was originally needed to
    filter stale signals from timeout-driven spurious loop iterations, but
    those no longer exist thanks to the HasUnprocessedMessages guard.

    * Skip hanging multi-turn declarative integration tests
    
    The ValidateMultiTurnAsync tests (ConfirmInput.yaml, RequestExternalInput.yaml)
    hang indefinitely in CI, blocking the merge queue. The hang is SDK-independent
    (reproduces with both Azure.AI.Projects 1.2.0-beta.5 and 2.0.0-beta.1) and
    is a pre-existing issue in the declarative workflow multi-turn test logic.
