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

  * Skip flacky UT
  
  * Ignore org-level GitHub App checks in merge-gatekeeper
  
  Add Cleanup artifacts, Agent, Prepare, and Upload results to the
  ignored list. These are check runs created by an org-level GitHub App
  (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.

  The ValidateMultiTurnAsync tests (ConfirmInput.yaml, RequestExternalInput.yaml)

  (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.

• .NET: AzureAI Package - Skip tool validation when UseProvidedChatClientAsIs is true (#4389)

  * Skip tool validation when UseProvidedChatClientAsIs is true (#3855)
  
  When GetAIAgentAsync is called with ChatClientAgentOptions.UseProvidedChatClientAsIs = true,
  skip requireInvocableTools validation so users can handle function calls manually
  via custom ChatClient middleware without needing to provide matching AIFunction tools.
  
  Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
  
  * Simplify requireInvocableTools expression per review feedback
  
  UseProvidedChatClientAsIs is a non-nullable bool, so use ! operator
  instead of != true for clarity.
  
  Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
  
  * Decouple tool matching from validation and add tool preservation test (#3855)
  
  Always match provided AIFunctions to server-side function definitions
  regardless of requireInvocableTools flag. Only throw when validation
  is required and no match is found. This ensures UseProvidedChatClientAsIs
  still preserves user-provided AIFunction tools instead of falling back
  to the broken ResponseToolAITool wrapper.

• .NET: Fixing issue with invalid node Ids when visualizing dotnet workflows. (#4269)

  * Fix Mermaid rendering errors in WorkflowVisualizer.ToMermaidString
  
  Fix two bugs in the Mermaid diagram output:
  
  1. Use safe node aliases (node_0, node_1, ...) instead of raw executor IDs
     as Mermaid node identifiers. Raw IDs containing spaces, dots, or
     non-ASCII characters (e.g. Japanese) caused Mermaid parse errors.
  
  2. Fix conditional edge arrow syntax from '.--> ' (invalid) to '.-> '
     (valid Mermaid dotted arrow syntax).
  
  Fixes #1406
  
  Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
  
  * Use recognizable sanitized IDs for Mermaid node identifiers\n\nReplace generic node_0/node_1 aliases with IDs derived from the original\nexecutor names. ASCII letters, digits, and underscores are preserved;\nother characters become underscores (collapsed, trimmed). Leading digits\nget an n_ prefix. Collisions are resolved with a numeric suffix.\n\nThis keeps node IDs readable in the Mermaid source while the display\nlabels continue to show the full original names."
  
  * Remove issue number references from test names and comments"
  
  * Address PR review feedback from Copilot\n\n- Add Throw.IfNull(id) guard to SanitizeMermaidNodeId\n- Add safety limit (10,000) to collision resolution loop\n- Restore missing edge assertions (middle1/middle2 --> end)\n- Fix comment to show actual sanitized ID (n_1_User_input)\n- Use stricter regex in Unicode test (must start with letter/underscore)"
  
  * Address second round of PR review feedback\n\n- Escape node display labels via EscapeMermaidLabel to handle quotes,\n  brackets, and newlines in executor IDs\n- Fix XML doc on SanitizeMermaidNodeId to accurately describe that\n  existing consecutive underscores in input are preserved\n- Restore specific edge assertion (mid --> end) in conditional edge test\n- Restore fan-in routing assertions (s1/s2 through intermediate node,\n  no direct edges to t) in fan-in test"

• .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.
  
  Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
  
  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

  When parsing JSON arrays containing objects without a predefined schema,
  `DetermineElementType()` was creating a `VariableType` with an empty
  (non-null) schema via `targetType.Schema?.Select(...) ?? []`. This caused
  `ParseRecord` to take the schema-based parsing path, iterating over zero
  schema fields and silently discarding all JSON properties.
  
  The fix checks `targetType.HasSchema` and falls back to
  `VariableType.RecordType` (which has `Schema = null`) when no schema is
  defined, ensuring `ParseRecord` takes the dynamic `ParseValues()` path
  that preserves all JSON properties.
  
  Closes #4195
  
  * test: add regression tests for schema-less JSON array-of-objects parsing (#4195)
  
  Add two regression tests to JsonDocumentExtensionsTests:
  
  1. ParseRecord_ObjectWithArrayOfObjects_NoSchema_PreservesNestedProperties
     - Parses a JSON object containing an array of objects using
       VariableType.RecordType (no schema) and verifies that nested
       object properties (name, role) are preserved in each element.
     - This is the exact scenario from issue #4195 where objects in
       arrays were being returned as empty dictionaries.
  
  2. ParseList_ArrayOfObjects_NoSchema_PreservesProperties
     - Parses a JSON array of objects directly via ParseList with
       VariableType.ListType (no schema) and verifies all properties
       are preserved.
  
  Both tests follow the existing Arrange/Act/Assert pattern and would
  have failed before the DetermineElementType() fix (empty dictionaries
  instead of populated ones).

  * refactor: Normalize Run/RunStreaming with AIAgent
  
  * refactor: Clarify Session vs. Run -level concepts
  
  * Rename RunId to SessionId to better match Run/Session terminology in AIAgent
  * [BREAKING]: Will break existing checkpointed sessions in CosmosDb due to field rename
  
  * refactor: Rename and simplify interface around getting typed data out of ExternalRequest/Response
  
  * Also adds hints around using value types in PortableValue
  
  * refactor: Rename AddFanInEdge to AddFanInBarrierEdge
  
  This will prevent a breaking change later when we introduce a programmable FanIn edge, analogous to the FanOut edge's EdgeSelector.
  
  The goal, in the long run is to support a number of different FanIn scenarios, with naive FanIn (no barrier) by default, similar to FanOut.
  
  * refactor: AsAgent(this Workflow, ...) => AsAIAgent(...)

• .NET: Remove FunctionCalls and Tool Messages from Handoff passed messages (#3811)

  * Fix handoff orchestration not passing user message to handoff target agent (#3161)
  
  Filter out internal handoff function call and tool result messages before
  passing conversation history to the target agent's LLM. These messages
  confused the model into ignoring the original user question.
  
  * Add handoff tool call filtering behavior and enhance workflow builder
  
  - Introduced HandoffToolCallFilteringBehavior enum to specify filtering behavior for tool call contents in handoff workflows.
  - Updated HandoffsWorkflowBuilder to support customizable handoff instructions and tool call filtering behavior.
  - Enhanced HandoffAgentExecutor to utilize new filtering options for improved message handling during agent handoffs.
  
  * Enhance handoff message filtering logic and add unit tests for filtering behaviors
  
  * Refactor HandoffMessagesFilter to remove unused handoff function names and enhance filtering logic for non-handoff function calls
