* Fix FoundryAgent stripping model from PromptAgent requests
Move run_options.pop('model', None) inside the _uses_foundry_agent_session()
conditional so that model is only stripped for hosted agent sessions (where
the server manages the model) and preserved for PromptAgent requests that
require it in the Responses API call.
Fixes#5525
* test: add coverage for resp_* continuation preserving model
Adds test_raw_foundry_agent_chat_client_prepare_options_preserves_model_for_resp_continuation
to explicitly verify that HostedAgent v1 / v2-no-session paths (where conversation_id
starts with resp_) preserve model and previous_response_id without triggering the
hosted-session gate.

* Promote Workflows.Declarative packages to stable versions
* Address PR feedback: enable package validation on GA declarative packages
Both Workflows.Declarative and Workflows.Declarative.Mcp set IsReleased=true
but were disabling package validation, bypassing the repo's GA convention
(see dotnet/nuget/nuget-package.props which auto-enables validation when
IsReleased=true).
Re-enable validation by removing the local EnablePackageValidation=false
overrides and pointing PackageValidationBaselineVersion at 1.8.0-rc1 (the
latest published version of each package). This catches accidental breaking
changes between RC and the first GA. Future GAs should bump the baseline to
the previous GA version.
Verified locally: dotnet build -c Release on both projects runs
RunPackageValidation -> APICompat ran successfully without finding any
breaking changes.

* Python: Fix OTLP HTTP base-endpoint losing /v1/{signal} auto-append
Per the OTel spec, OTEL_EXPORTER_OTLP_ENDPOINT is a *base* URL for HTTP —
the SDK auto-appends /v1/traces, /v1/metrics, /v1/logs when it reads the
env var directly. Signal-specific endpoint env vars are *full* URLs used
verbatim.
_get_exporters_from_env read the base endpoint and forwarded it as the
constructor ``endpoint=`` argument, which the SDK always treats as a full
signal URL. As a result, with OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4318
and HTTP protocol, the exporter sent to http://localhost:4318 instead of
http://localhost:4318/v1/traces (and likewise for metrics/logs).
Replicate the spec's auto-append here when falling back to the base
endpoint under HTTP. gRPC behavior is unchanged.
* Python: Fix mypy type errors in OTLP endpoint assignment
Pre-declare traces_endpoint, metrics_endpoint, logs_endpoint as
str | None before the if/else block. Mypy inferred str from the
if-branch f-string assignments and then rejected the str | None
expressions in the else-branch as incompatible.

* Python: fix(evals): address PR review feedback
Addresses 4 Copilot review comments on PR #6101:
1. assert_dimension_score_at_least: drop the (not evaluator or found_any) guard so require_applicable=True correctly raises when the named evaluator produces no entries for the dimension. Adds TestRubricAssertions covering the regression.
2. GeneratedEvaluatorRef docstring: reword to describe actual behaviour (pinning recommended, not required) so it matches the dataclass default and FoundryEvals warning path.
3. _poll_generation_job: switch from asyncio.get_event_loop() to get_running_loop() and bound the per-iteration sleep by remaining time, matching _poll_eval_run.
4. generate_rubric: type category as Literal['quality','safety'] and validate at the entry point with a ValueError; drop the silent 'invalid -> quality' rewrite in _generation_job_to_ref. Adds a regression test.

* Python: feat(foundry-evals): hosted-agent-aware rubric generation
* Auto-detect hosted Foundry agents in agent_as_eval_source: when the
agent's chat_client exposes a string agent_name (the convention used
by RawFoundryAgentChatClient for PromptAgents/HostedAgents), emit a
type='agent' EvalGenerationSource so the service fetches instructions
and tools from the agent registry instead of relying on the local
wrapper (which holds neither for hosted agents).
* Add hosted_agent_version kwarg and a new agent_version field on
EvalGenerationSource so PromptAgent runs can pin to a specific hosted
version for reproducible rubric generation.
* Add force_prompt_source escape hatch to bypass auto-detection and
always emit a rendered prompt dossier - useful when the local wrapper
carries overrides the service-side agent doesnt see.
* Fix _to_sdk_source for dataset sources: SDK ctor takes name=/version=,
not dataset_name=/dataset_version=. The mismatch would raise TypeError
against the real azure-ai-projects 2.3.0a* SDK; only unmocked
integration paths were affected.
Tests cover: auto-detection happy path, versionless hosted agent,
explicit hosted_agent_version forwarding, force_prompt_source override,
non-string chat_client attrs (MagicMock test doubles) not mis-detected,
agent_version forwarded through _to_sdk_source, and the corrected
dataset SDK kwarg names.

* fix(foundry-evals): accept canonical dimension_scores key per docs
The published Foundry rubric-evaluator output (Microsoft Learn 'Rubric evaluators' reference) places per-dimension breakdowns under properties.dimension_scores, not properties.rubric_scores. The parser now tries dimension_scores first and falls back to rubric_scores for preview-build compatibility, and tolerates non-list payloads (e.g. MagicMock auto-attrs) by trying the next candidate when parsing yields zero entries.

* feat(foundry-evals): add manual create_rubric_evaluator
Adds FoundryEvals.create_rubric_evaluator as the agent-framework surface over project_client.beta.evaluators.create_version. This is the manual counterpart to generate_rubric: callers supply RubricDimension instances (authored locally, ported from another framework, or hand-tuned) and we POST a RubricBasedEvaluatorDefinition. The service auto-attaches the non-editable residual dimension (general_quality for quality, general_policy_compliance for safety).
Per the Microsoft Learn 'Rubric evaluators' reference, the auto-generation path (create_generation_job) is primarily a portal/UI feature; external SDK clients with rich local agent context are better served by manual create_version. This keeps generate_rubric for users who want to round-trip through a Foundry-registered agent.
Validation up front: weight must be in [1,10], ids unique, descriptions non-empty, pass_threshold in [0,1]. The returned GeneratedEvaluatorRef is identical in shape to one obtained from generate_rubric, so downstream evaluators= lists work unchanged.

* samples(foundry-evals): manual rubric sample + namespace re-exports
Adds evaluate_with_manual_rubric_sample.py demonstrating the end-to-end dev scenario for FoundryEvals.create_rubric_evaluator: hand-author a list of RubricDimension, register via create_rubric_evaluator, then use the pinned GeneratedEvaluatorRef alongside built-in evaluators in an agent regression run.
Also re-exports RubricDimension, GeneratedEvaluatorRef, build_sources, and load_evals_config from agent_framework.foundry (both the lazy runtime shim and the type stub) so the rubric samples can import everything from a single namespace; the auto-generate sample was previously broken because the shim was missing build_sources / load_evals_config.
Updates the foundry-evals README with a chooser entry for the two rubric paths.

* feat(foundry-evals): remove rubric creation flows; keep consumption only
Reframes agent-framework as a pure consumer of Foundry rubric evaluators: scoring against rubrics that already exist (authored in the Foundry portal or via the dedicated SDK / REST surface) instead of creating them from the SDK.
Removed creation surface area:
- FoundryEvals.generate_rubric (auto-generate path) and create_rubric_evaluator (manual path), plus all _GenerationSdkTypes / _ManualRubricSdkTypes / _to_sdk_dimensions / _coalesce_generation_sources / _to_sdk_source / _poll_generation_job / _generation_job_to_ref / _evaluator_version_to_ref / _get_beta_evaluators / _import_*_sdk_types helpers.
- EvalGenerationSource (the input source discriminator), RubricDimension (the input dimension type), agent_as_eval_source / workflow_as_eval_source / _detect_hosted_foundry_agent helpers, and the YAML-config loader (_evals_config.py with RubricGenerationSpec / RubricSourceSpec / parse_evals_config / load_evals_config / build_sources).
- BaseAgent.as_eval_source / Workflow.as_eval_source plus the _render_agent_dossier / _render_workflow_dossier helpers in core. These existed only to feed the now-removed generation pipeline.
- Samples evaluate_with_generated_rubric_sample.py, evaluate_with_manual_rubric_sample.py, and evaluators.yaml. Replaced with a short README section showing how to reference an existing rubric evaluator via GeneratedEvaluatorRef.
Kept (consumption surface):
- GeneratedEvaluatorRef, slimmed to (name, version, display_name). Still accepted alongside built-in evaluator strings in FoundryEvals(evaluators=[...]). Versionless refs still warn.
- RubricScore on EvalScoreResult.dimensions plus EvalResults.assert_dimension_score_at_least for per-dimension CI gates.
- _parse_dimension_entries / _extract_rubric_scores output parsing (both canonical dimension_scores and the legacy rubric_scores key).
Tests: 160/160 foundry unit tests and 71/71 core local-eval tests pass; pyright is clean across changed files. The pre-existing tests/core/test_telemetry.py::test_detect_hosted_fallback_import_error failure is unrelated and reproduces on the prior commit.

Adds a runnable end-to-end sample showing how to consume a pre-existing rubric evaluator created in Foundry: reference it with GeneratedEvaluatorRef(name, version), mix it with built-in evaluators in FoundryEvals, and gate CI with assert_dimension_score_at_least on a specific dimension.

Move all of them to the existing top-level imports; the symbols are the same across tests and the local imports were redundant.

* fix: safely serialize function-call arguments in core observability
Apply make_json_safe() to content.arguments in _to_otel_part() before
building the otel message dict, so that dataclass/framework payloads
(e.g. workflow request_info events) do not cause a TypeError when
_capture_messages() calls json.dumps().
Lift make_json_safe() into agent_framework._serialization (no new
external deps — dataclasses/datetime only) so the core observability
path can use it without a dependency on the ag-ui adapter.

TypeError at runtime.
- Wrap each call in try/except TypeError to handle callables with

- Convert dict keys to str() so that non-string keys (e.g. datetime,
int) cannot cause json.dumps to raise TypeError.

* Fix missing id on function_call_output in Foundry Hosting
The Foundry storage layer was rejecting responses with
"ID cannot be null or empty (Parameter 'id')" because
function_call_output items emitted by OutputConverter had no id on
the wire.
OutputItemFunctionToolCallOutput's public ctor only sets CallId and
Output; Id is read-only and only the SDK's internal ctor populates
it. OutputItemBuilder<T>.ApplyAutoStamps fills ResponseId and
AgentReference but not Id, so the itemId passed to
AddOutputItem<T>(itemId) was used only for event sequencing and the
serialized item went out with id=null.
Switch to stream.OutputItemFunctionCallOutput(callId, output), the
SDK convenience method that uses the internal ctor and stamps the
id. Add a regression test asserting the added/done events carry a
non-empty matching Id.

* ci: free disk space and relocate NuGet cache on ubuntu runners
The ubuntu-latest dotnet-build/test jobs were hitting No space left on device because the runner image only ships ~14 GB free on /. The full multi-TFM build plus the dotnet pack + console-app install-check exhausts that easily.
Add a reusable composite action .github/actions/free-runner-disk-space that runs on Linux runners only and:
* removes pre-installed toolchains we never use here (Android SDK, GHC/Haskell, CodeQL, PyPy, Ruby, Go, boost, vcpkg, etc.), prunes docker images, and disables swap (reclaims ~25-30 GB on /)
* relocates the NuGet package cache to /mnt/nuget via NUGET_PACKAGES env, since /mnt has ~75 GB free on hosted runners
Wire the action into the four ubuntu-touching jobs in dotnet-build-and-test.yml (dotnet-build, dotnet-test, dotnet-foundry-hosted-it, dotnet-test-functions). The action self-guards with runner.os == 'Linux' so the matrix legs that run on windows are unaffected.

* Initial plan
* Fix integration test worker crashes on Python 3.13
Three changes to prevent pytest-xdist workers from crashing during
Azure Functions integration tests:
1. Add `start_new_session=True` to subprocess on Linux so signals
(e.g. from test-timeout) cannot propagate between the func host
and the xdist worker process.
2. Add an overall 100-second budget to the fixture setup loop so
the retry logic never exceeds the 120-second test timeout. When
pytest-timeout's thread method fires during fixture setup and the
thread doesn't respond, it calls os._exit() which kills the
xdist worker – this is the root cause of the "Not properly
terminated" crashes.
3. Remove the `UV_PYTHON: "3.10"` workaround from both workflow
files so integration tests actually run on Python 3.13.

* Fix func worker segfault on Python 3.13 by redirecting worker to Python 3.12
The Azure Functions Python worker crashes with SIGSEGV (exit code 139)
on Python 3.13 due to protobuf C extension (google._upb) compatibility
issues. When the test runner uses Python >=3.13, the conftest now
automatically finds a compatible Python 3.10-3.12 and sets
languageWorkers__python__defaultExecutablePath so the func host uses
it for the worker process.
The CI setup action also ensures Python 3.12 is available on the
runner, falling back to uv python install if the system doesn't have
it.

* Address code review: add path validation, clarify version range and config key format
Co-authored-by: larohra <41490930+larohra@users.noreply.github.com>
* Run func worker natively on Python 3.13 by disabling dependency isolation
Replace the Python 3.12 redirect workaround with the proper fix:
set PYTHON_ISOLATE_WORKER_DEPENDENCIES=0 on Python >=3.13.
The segfault (exit code 139) is caused by the Azure Functions worker's
module isolation mechanism conflicting with protobuf's C extensions
(google._upb) on Python 3.13. Disabling isolation lets the worker
load dependencies from the app's own environment, which avoids the
crash while keeping everything running on Python 3.13.

* Fix streaming artifact coalescing and address PR review feedback
A2AExecutor fix:
- Generate a stable artifact_id per stream in _run_stream so all streaming
chunks share the same ID, enabling proper append=True coalescing per the
A2A spec (TaskArtifactUpdateEvent with same artifactId).
- Previously, item.message_id was None for OpenAI/Foundry streaming updates,
causing the SDK to generate a new random UUID per token (100+ separate
artifacts instead of 1 appended artifact).
Sample improvements:
- Replace join workaround with response.text now that coalescing works
- Add background=True to stream reconnection resume call (required for
continuation token emission on in-progress tasks)
- Fix type ignore specificity in polling sample

* Bump Azure.AI.AgentServer.* package versions
* Align Azure.Core/System.ClientModel to AgentServer transitive deps
Bump Azure.Core 1.55->1.56 and System.ClientModel 1.11->1.12 to match Azure.AI.AgentServer.* requirements, and add explicit references in transitive-pinning-off Foundry consumers to avoid CS1705/MSB3277 version conflicts.
Map A2A protocol message_id to AgentResponseUpdate.message_id in two paths
where it was previously omitted, aligning with .NET behavior:
1. Standalone A2AMessage: set message_id=msg.message_id (matches .NET
ConvertToAgentResponseUpdate(Message) which sets both ResponseId and
MessageId to message.MessageId)
2. TaskStatusUpdateEvent (terminal/input_required): set
message_id=message.message_id (matches .NET which sets
MessageId=statusUpdateEvent.Status.Message?.MessageId)

* 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.

* Adding AgentFileStore and FileAccessProvider to support file ased operations for agents.
* Address PR review feedback on FileAccessProvider
- Probe symlinks on the unresolved candidate path so in-root symlinks
cannot silently pass and out-of-root symlinks surface the correct
error message.
- Validate matching_lines elements in FileSearchResult.from_dict and
raise a clean ValueError for non-mapping entries.
- Cap search regex pattern length (256 chars) via a new
_compile_search_regex helper to mitigate ReDoS, and surface the cap
in the file_access_search_files tool description.
- Skip non-UTF-8 files during filesystem search instead of aborting
the entire directory walk.
- Replace the module-scope trailing string in the data-processing
sample with comments to avoid Ruff B018.
- Remove the checked-in working/region_totals.md sample artifact so
the save flow works from a clean checkout.
- Expand the Windows stdout reconfiguration comment in task_runner.py
for clarity.
- Add tests for invalid/oversize regex, non-UTF-8 file search, and
in-root symlink rejection.

* Fix mypy redundant-cast in FileSearchResult.from_dict
Use cast(list[object], ...) instead of cast(list[Any], ...) so the
cast represents a real type change (lists are invariant) and is no
longer flagged by mypy as redundant, while still satisfying pyright's
reportUnknownVariableType. Matches the existing pattern in _memory.py.

* Tighten path normalization and directory resolution in FileAccess
- _normalize_relative_path now strips surrounding whitespace up front
so leading/trailing spaces never leak into file segments, and
rejects trailing path separators for file paths so 'foo/' is no
longer silently coerced to 'foo'.
- FileSystemAgentFileStore._resolve_safe_directory_path normalizes
with is_directory=True and maps an empty normalized result to the
root. This matches InMemoryAgentFileStore so whitespace-only
directory inputs resolve to the root instead of raising.
- Added tests for whitespace stripping, trailing-separator rejection,
and whitespace-only directory listing on the filesystem store.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Harden FileAccess search and atomic save in store API
- Add wall-clock timeout (10s) around regex scans so a pathological pattern (e.g. `(a+)+`) below the length cap cannot stall the event loop.
- Offload the InMemoryAgentFileStore regex scan to a worker thread, matching the filesystem store.
- Fail closed when `Path.is_symlink` raises during the safe-path probe so a permission error cannot silently bypass the symlink/reparse-point rejection.
- Add `overwrite: bool = True` to `AgentFileStore.write_file`; the in-memory store performs the check under the existing lock and the filesystem store uses `open(mode='x')` so concurrent callers cannot race past `overwrite=False`.
- `file_access_save_file` now relies on the atomic store call instead of a separate `file_exists` round-trip.

* Fix Python 3.10 timeout handling and add directory arg to list/search tools
- Catch asyncio.TimeoutError in _run_search_with_timeout. In Python 3.10
asyncio.wait_for raises asyncio.exceptions.TimeoutError, which is
distinct from the builtin TimeoutError (the two were unified in 3.11).
Catching the asyncio alias works on every supported version.
- Add an optional directory parameter to file_access_list_files and
file_access_search_files so agents can enumerate / scope searches to
nested folders, not just the store root.

* Address FileAccess review feedback: case, errors, signal, TOCTOU
- InMemoryAgentFileStore now stores (display_name, content) so list_files
and search_files return the original-case names callers wrote, matching
the behaviour of FileSystemAgentFileStore on case-preserving filesystems
and removing the silent in-memory vs. on-disk contract divergence.
- FileSystemAgentFileStore.read_file raises ValueError instead of letting
UnicodeDecodeError bubble for binary / non-UTF-8 input, restoring
symmetry with search_files (which still skips) and giving the tool
layer a recoverable type to translate.
- Tool wrappers now catch ValueError and OSError around every operation
and surface them as readable strings, so 'you used ..' and 'the file
already exists' are both reported to the model the same way instead of
the former crashing out as an unhandled exception.
- _search_files_sync logs per skipped non-UTF-8 file at WARNING and an
aggregate INFO summary so operators can distinguish 'no matches' from
'half the corpus was unreadable'.
- FileSystemAgentFileStore softens its docstrings to acknowledge the
inherent probe-then-open TOCTOU window. On POSIX both read and write
now pass O_NOFOLLOW so the kernel refuses if the leaf segment becomes
a symlink between the probe and the open. Windows has no equivalent
flag; the limitation is documented.
- Tests cover: case preservation on list/search, ValueError on non-UTF-8
read at the store and tool layer, tool-layer string responses for
path-traversal and oversized-regex inputs, search-skip log output,
symlink rejection on delete/search/list, and symlinked intermediate
directory rejection.

* Address FileAccess nit comments: docstrings, enumerate, opt-in delete approval
- Expand FileSearchMatch/FileSearchResult.to_dict docstrings to explain why
the override is needed (__slots__ defeats the mixin's __dict__ iteration)
and why exclude/exclude_none are accepted-but-ignored (mixin signature
compatibility for callers like to_json).
- Use enumerate(lines, start=1) in _search_file_content so the +1 below is
no longer needed; rename loop variable to line_number for clarity.
- Add opt-in require_delete_approval: bool = False on FileAccessProvider.
When True, file_access_delete_file is registered with approval_mode
'always_require' so the host must approve every delete. Default False
preserves current behaviour and matches the .NET reference, but
deployments that want a safer-by-default posture can enable it.
- Add tests covering both delete approval modes.

* FileAccess: require delete approval by default
Flip the default for FileAccessProvider(require_delete_approval=...) from
False to True so destructive deletes are gated by host approval out of the
box. Callers that want the previous autonomous behaviour (which matches the
.NET reference) can pass require_delete_approval=False.
Tests updated accordingly.
