The old guide documented the move away from setup_observability(otlp_endpoint=...)
which was an earlier-release API change unrelated to this PR and stale enough that
it's more confusing than helpful at this point. Replace it with a short note on the
single migration this PR introduces: callers of
enable_instrumentation(enable_sensitive_data=True) should switch to
enable_sensitive_telemetry(). Cross-link to the Disabling instrumentation section
for the rare 'force on without enabling sensitive data' use case where
enable_instrumentation() still applies.

- opentelemetry-sdk is no longer a hard dependency; it is lazily imported by
create_resource(), create_metric_views(), and configure_otel_providers()
with a clear ImportError when missing. Day-to-day instrumentation works
with opentelemetry-api alone provided some other component configures the
global OpenTelemetry providers (Azure Monitor, an APM agent, application
bootstrap, etc.).
- opentelemetry-semantic-conventions-ai is no longer used anywhere in the
source; remove it from the listed dependencies.

Replace 'no telemetry will be emitted no matter what' (which is too strong,
since callers can still pass force=True or mutate private attributes) with
language framing the disable as a user-intent contract that library and
framework code is expected to honor: the framework actively short-circuits
the public enable paths, force=True and private-attribute writes are
acknowledged as out-of-contract escape hatches that integrations should
not use on the user's behalf.

Add a "Disabling instrumentation" section to the observability sample README
that walks through:
- The distinction between the ENABLE_INSTRUMENTATION env var (initial,
non-sticky) and disable_instrumentation() (process-wide, sticky).
- Why the sticky semantics matter: framework integrations like
FoundryChatClient.configure_azure_monitor() can call
enable_instrumentation() as part of their setup, and the user's opt-out
needs to win.
- All five surfaces guarded by the sticky disable (property reads, public
enable functions, configure_otel_providers, direct attribute writes,
is_user_disabled-aware integrations).
- The force=True escape hatch on both enable_instrumentation() and
enable_sensitive_telemetry().
- How third-party integrations should consult OBSERVABILITY_SETTINGS.is_user_disabled.
- The limits of the disable (does not tear down existing providers /
in-flight spans / third-party instrumentation, does not persist across
processes).
Cross-links the new section from the ENABLE_INSTRUMENTATION row in the env
vars table.

Add a public disable_instrumentation() entry point so users can explicitly opt
out of Agent Framework telemetry, with a sticky-disable flag that makes the
user's intent "leading" — no framework code path (foundry's
configure_azure_monitor, configure_otel_providers, enable_instrumentation,
enable_sensitive_telemetry, or direct OBSERVABILITY_SETTINGS.enable_*
writes) can re-enable instrumentation until the user explicitly clears the
disable with enable_instrumentation(force=True) /
enable_sensitive_telemetry(force=True).
Also addresses the two remaining unresolved review threads on the PR:
1. test_observability_settings_defaults_instrumentation_true pins the new
"ENABLE_INSTRUMENTATION defaults to True when env unset" behavior.
2. test_enable_instrumentation_reads_env_sensitive_data restores coverage
for the post-import load_dotenv() fallback path.
Implementation:
- ObservabilitySettings.enable_instrumentation / enable_sensitive_data become
properties backed by _enable_*. While _user_disabled is True, the getters
return False and the setters drop True writes (defense in depth so third-
party writes can't subvert the disable).
- Public is_user_disabled read-only property lets integrations (e.g. foundry's
configure_azure_monitor) cheaply check the disable state without poking at
privates.
- enable_instrumentation() and enable_sensitive_telemetry() short-circuit with
an info log when disabled; gain a force=True kwarg that clears the disable.
- configure_otel_providers() still creates providers / exporters / views so a
later force-enable can use them, but logs an info message when called while
disabled.
- Foundry's FoundryChatClient.configure_azure_monitor and
FoundryAgent.configure_azure_monitor early-return when the user has
disabled, so Azure Monitor's global providers aren't installed unnecessarily.
Tests: 11 new tests covering default-on, env re-read at call time, sticky
behavior against each re-enable surface (enable_instrumentation,
enable_sensitive_telemetry, configure_otel_providers, direct attribute
writes), force=True override, re-arming the disable, and the __all__ export.

* Python: DevUI: tighten default access controls and CORS posture
Adjusts the default configuration of the DevUI server so the out-of-the-box
posture matches what most callers expect when running locally. Adds explicit
opt-outs for callers who need the previous behavior.
- DevServer gains auth_enabled and auth_token constructor params; auth is on by
default. Auto-generates and logs a token when none provided.
- CORS default is an empty allowlist on every host. Callers wanting cross-origin
pass cors_origins explicitly.
- Streaming /v1/responses no longer sets Access-Control-Allow-Origin directly;
CORSMiddleware owns all CORS decisions.
- Loopback binds enforce a Host-header allowlist.
- /meta moved out of the auth bypass list (was alongside /health and /).
- serve() default flipped to auth_enabled=True; passes auth args through to
DevServer instead of using env-var indirection.
- CLI: --auth opt-in replaced with --no-auth opt-out; --auth-token preserved.
- Tests cover the eight behaviors above in test_server.py.
* Python: DevUI: address PR review comments
- /meta now derives auth_required from self.auth_enabled instead of
reading DEVUI_AUTH_TOKEN, so the auto-generated and explicit
auth_token paths report correctly.
- Reorder middleware so the loopback Host-header allowlist is registered
last; Starlette wraps later-added middleware around earlier-added ones,
so the host check now runs outermost (before CORS/auth) as intended.
- Rework comments to describe the behavior rather than threat scenarios.
- Streaming-headers and CORS tests now construct the server with an
explicit auth_token and send a Bearer header, so the assertions
actually exercise the streaming/CORS path instead of short-circuiting
in the auth middleware.
Fixes microsoft/agent-framework#3295. When the OpenAI Responses chat
client sends a request that carries previous_response_id / conversation_id
/ conversation, the server already has the prior turn's response items
and rejects duplicates with "Duplicate item found with id fc_xxx". The
chat client was re-sending them inline whenever the input messages still
carried the items in additional_properties (workflow replay, history
providers, etc.), which broke any tool-using agent with persistent
history.
Decisions:
- Single chokepoint: _prepare_message_for_openai. When the resulting
request uses service-side storage, drop function_call, reasoning,
approval-request/response, and local-shell-call items from the wire
input. Keep function_result with its call_id; the server pairs it to
the prior function_call via that key.
- function_result is preserved unconditionally except for the local-shell
variant, which carries its own server-issued item id.
- No public API change. Wire format change is subtractive and only on
requests that would otherwise 400.
- Re-pointed the strict-xfail in test_full_conversation.py from #4047 to
#3295. Kept xfail because the test asserts executor-level session-id
clearing, which is the defense-in-depth half tracked by 3295-03; this
slice closes the wire-level half.
Files:
- python/packages/openai/agent_framework_openai/_chat_client.py: strip
rule applied alongside the existing reasoning-item branch.
- python/packages/openai/tests/openai/test_openai_chat_client.py: four
new tests pin the contract (function_call, approval, local-shell-call
stripped under storage; everything kept without storage). Updated
pre-existing tests that exercised the storage-on path to either pass
request_uses_service_side_storage=False explicitly or assert the new
strip behavior.
- python/packages/foundry/tests/foundry/test_foundry_chat_client.py:
same explicit storage-off opt-in for the inherited test.
- python/packages/core/tests/workflow/test_full_conversation.py:
re-pointed xfail reason to #3295 and the executor-level follow-up.
Notes for next iteration:
- 3295-01 (HITL wire-format validation against live OpenAI/Foundry) was
not run; it requires the user's API credentials. The PRD design is
locked but the empirical confirmation is still pending. If script 3
fails on either provider, this slice may need to be revisited.
- 3295-03 (clear service_session_id in AgentExecutor on full-history
replay) remains open. After it lands the xfail in
test_full_conversation.py can be removed.
- pytest was not run in this iteration because uv-based pytest commands
required interactive approval. Validation rests on careful reading;
next iteration should run the openai + core test suites.

* fix(python): prevent MCP message_handler deadlock on notification reload
When an MCP server sends a notifications/tools/list_changed or
notifications/prompts/list_changed notification, the message_handler
previously awaited load_tools()/load_prompts() directly. Since the
handler runs on the MCP SDK's single-threaded receive loop, this
caused a deadlock: load_tools() sends a list_tools request and waits
for its response, but the receive loop cannot deliver that response
while blocked in the handler.
This manifested as a timeout in call_tool(), which then surfaced as
"Error: Function failed." to the model instead of the real tool
output. The MATLAB MCP server reliably triggers this because it sends
a tools/list_changed notification during tool execution.
Fix: schedule reloads as background asyncio.Tasks via a new
_schedule_reload() helper, freeing the receive loop immediately.

- Waiting for publish notification (the step that was failing)
- Waiting for orchestration completion

* Add RetryFact to DurableTask and AzureFunctions integration tests
These tests interact with LLMs via stdin/stdout (DurableTask) or HTTP
(AzureFunctions) and are inherently non-deterministic. Unlike the Python
side which uses pytest-retry, the dotnet tests had no retry mechanism
and a single transient failure would fail the entire CI run.
Changes:
- Switch [Fact] to [RetryFact(2, 5000)] on all LLM-dependent tests
across ConsoleAppSamplesValidation, ExternalClientTests,
WorkflowConsoleAppSamplesValidation, and AzureFunctions SamplesValidation
- Add re-prompt mechanism to LongRunningToolsSampleValidationAsync:
if the LLM doesn't invoke the tool within 60s, re-send the prompt
(up to 2 retries) instead of burning the full timeout
- Reduce LongRunningTools timeout from 240s to 180s (re-prompt makes
the extra buffer unnecessary)
- Leave simple/deterministic tests as [Fact] (SingleAgent, unit tests)

* fix: wrap asyncio.CancelledError in ToolException in _connect_on_owner (#5667)
asyncio.CancelledError is a BaseException (not Exception) in Python 3.8+.
When an MCP server is unreachable, the MCP library's internal anyio task
group raises CancelledError, which escaped all three 'except Exception'
handlers in _connect_on_owner(). This propagated through
_run_lifecycle_owner -> _run_on_lifecycle_owner -> connect -> __aenter__,
bypassing user except Exception blocks entirely.
Fix: change the three except-Exception clauses in _connect_on_owner to
'except (Exception, asyncio.CancelledError)' so spurious CancelledErrors
from the MCP transport layer are caught and wrapped in ToolException,
consistent with the method's documented contract.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* fix(mcp): propagate genuine task CancelledError in connect() (#5667)
On Python >= 3.11, check task.cancelling() > 0 before wrapping
CancelledError as ToolException in the three except blocks inside
_connect_on_owner(). When the current task is being cancelled by its
caller, the CancelledError now propagates after cleanup, consistent
with the existing pattern at _mcp.py:560-564 and _runner.py:115-120.
On Python < 3.11 task.cancelling() is unavailable, so MCP-internal
CancelledErrors still cannot be reliably distinguished from
caller-driven cancellation; they continue to be wrapped as
ToolException with a comment documenting the trade-off.
Tests:
- Add cleanup assertion to transport-creation CancelledError test
- Add MCPStdioTool variants exercising the 'command' message branches
for both transport-creation and initialize CancelledError paths
- Add Python 3.11+-gated tests verifying genuine task cancellation
propagates (and still cleans up) for transport and initialize stages

* fix(mcp): log CancelledError with exc_info before wrapping in ToolException (#5667)
CancelledError inherits from BaseException (not Exception) on Python >= 3.8,
so the 'inner_exception=ex if isinstance(ex, Exception) else None' guard
always yields None for CancelledError. This means ToolException.__init__
calls logger.log(level, message, exc_info=None), dropping the traceback.
Add an explicit logger.debug(error_msg, exc_info=ex) before each
raise ToolException(...) in the three CancelledError handlers so the
full traceback is preserved in debug logs when MCP-internal cancellation
is wrapped rather than propagated.

* Address review feedback for #5667: Python: [Bug]: Error Handling Issue regarding Python MCPStreamableHTTPTool Class
* refactor(_mcp): extract cancellation helper, fix session error msg and exc_info
- Extract _should_propagate_cancelled_error() helper to eliminate duplicated
genuine-cancellation detection logic across the three connect() except blocks
- Fix session-creation ToolException message to include exception details
(e.g. 'Failed to create MCP session: <ex>') matching the transport and
initialize failure paths
- Change exc_info=ex to exc_info=True in all three logger.debug() calls
for idiomatic logging
- Add tests for _should_propagate_cancelled_error helper
- Add regression test asserting session error message includes exception text
- Add test verifying logger.debug is called with exc_info=True

* refactor: factor out _close_and_check_cancelled helper in _connect_on_owner
Addresses review comment on PR #5687:
1. Add _close_and_check_cancelled() helper method that combines
_safe_close_exit_stack() + _should_propagate_cancelled_error() into a
single await-able call. This eliminates the duplicated close-then-check
pattern that appeared identically in all three connect phases (transport,
session, initialize), reducing future drift risk.
2. Comments 2 and 3 (missing {ex} in session error message and non-idiomatic
exc_info=ex) were already addressed in the current code: all error messages
include {ex} and all logger.debug calls use exc_info=True.
3. Add test_connect_genuine_cancellation_during_session_creation_propagates
to cover the previously untested genuine-cancellation path in the
session-creation phase (transport and initialize phases already had tests).

* feat(anthropic): add base_url parameter to AnthropicClient and RawAnthropicClient
Add base_url support to AnthropicSettings TypedDict, RawAnthropicClient,

Add regression tests asserting that when both ANTHROPIC_BASE_URL is set

AnthropicClient / RawAnthropicClient, the explicit kwarg wins.
This closes the priority-ordering contract (explicit arg > env var) that
the existing tests left implicit.

When the operating mode is changed externally (e.g. via a slash-command handler
calling set_agent_mode), the agent's chat history still shows the prior set_mode
tool call near the end. Updating only the system instructions is insufficient —
models tend to anchor on the recent tool call and ignore the new mode.
Mirror the .NET AgentModeProvider behavior: when set_agent_mode detects an actual
mode change, record the previous mode in provider state. On the next before_run,
the provider pops that flag and injects a user-role notification message
announcing the switch, so the most recent context unambiguously reflects the
current mode. The agent-driven set_mode tool path bypasses this so it does not
trigger a redundant notification on its own change.

* Remove Foundry toolbox helpers; standardize on MCP for toolbox consumption
- Remove RawFoundryChatClient.get_toolbox() and its fetch_toolbox import
- Remove fetch_toolbox, select_toolbox_tools, get_toolbox_tool_name,
get_toolbox_tool_type, FoundryHostedToolType, ToolboxToolSelectionInput
from agent_framework_foundry._tools
- Remove ExperimentalFeature.TOOLBOXES from _feature_stage.py (no consumers)
- Drop toolbox re-exports from agent_framework_foundry/__init__.py and
agent_framework.foundry namespace
- Update _sanitize_foundry_response_tool docstring to remove toolbox framing;
sanitization logic itself is unchanged
- Update _agent.py docstring: 'toolbox-fetched MCP' → 'hosted MCP'
- Delete tests/test_toolbox.py (all tests covered removed helpers)
- Update test_foundry_chat_client.py: rename/redoc tests that mentioned
toolbox but test sanitization that remains
- Delete foundry_chat_client_with_toolbox.py (bespoke toolbox API sample)
- Delete foundry_toolbox_context_provider.py (relied on select_toolbox_tools)
- Rename foundry_chat_client_with_toolbox_mcp.py →
foundry_chat_client_with_toolbox.py (canonical MCP pattern)
- Rewrite 04_foundry_toolbox/main.py to use MCPStreamableHTTPTool
- Update provider/README, context_providers/README, 04_foundry_toolbox/README

* fix(samples): update 06_files sample to consume toolbox via MCP (#5670)
Replace removed get_toolbox/select_toolbox_tools APIs with
MCPStreamableHTTPTool, using allowed_tools=["code_interpreter"] to
select only the code interpreter from the toolbox endpoint.
Update .env.example and README to use FOUNDRY_TOOLBOX_ENDPOINT
instead of TOOLBOX_NAME.

* Python: Remove bespoke Foundry toolbox helpers; standardize on MCP for toolbox consumption
Fixes#5670
* fix(#5670): resolve toolbox endpoint from TOOLBOX_NAME fallback; add namespace regression tests
- Add _resolve_toolbox_endpoint() helper in 04_foundry_toolbox/main.py and
06_files/main.py that prefers FOUNDRY_TOOLBOX_ENDPOINT but falls back to
deriving the MCP URL from FOUNDRY_PROJECT_ENDPOINT + TOOLBOX_NAME — fixing
the startup KeyError when agents are deployed via azd provision (which injects
TOOLBOX_NAME, not FOUNDRY_TOOLBOX_ENDPOINT).
- Update 04_foundry_toolbox/.env.example to use FOUNDRY_TOOLBOX_ENDPOINT
(consistent with 06_files).
- Add TOOLBOX_NAME env var to 06_files/agent.yaml so deployed agents have it
available for the fallback derivation.
- Update both READMEs to document the two ways to supply the toolbox endpoint.
- Add test_foundry_namespace_no_longer_exposes_toolbox_helpers() with negative
assertions for FoundryHostedToolType, get_toolbox_tool_name,
get_toolbox_tool_type, and select_toolbox_tools — guarding against accidental
re-introduction of removed symbols.

* fix(samples): fail fast on empty FOUNDRY_TOOLBOX_ENDPOINT; add unit tests
Addresses review feedback for #5670:
- In _resolve_toolbox_endpoint() (04_foundry_toolbox/main.py and
06_files/main.py) change the walrus-operator check from a truthy
test to an explicit 'is not None' guard. An explicitly set empty
string now raises ValueError immediately with a clear message
instead of silently falling through to the fallback URL
construction.
- Add tests/samples/hosting/test_toolbox_endpoint.py covering both
sample modules:
(a) FOUNDRY_TOOLBOX_ENDPOINT set → returned as-is
(b) FOUNDRY_TOOLBOX_ENDPOINT set to empty string → ValueError
(c) fallback constructs URL from FOUNDRY_PROJECT_ENDPOINT + TOOLBOX_NAME,
stripping trailing slashes
(d) neither variable group set → KeyError

BedrockChatClient was sending toolConfig.toolChoice even when no tools

be present whenever toolChoice is specified, causing a 400 validation
error.
Only set toolChoice when tool_config has a 'tools' key present.

- test_prepare_options_tool_choice_auto_without_tools_omits_tool_config

Verifies that toolConfig is omitted when tool_choice is set but no
tools are provided, preventing ParamValidationError from Bedrock.
* fix: address maintainer feedback — remove stray test file, raise ValueError for required without tools
1. Remove test_addition.py — stray duplicate of tests already in
python/packages/bedrock/tests/test_bedrock_client.py, missing all
necessary imports and would fail with NameError.
2. Change tool_choice='required' handling to raise ValueError when no
tools are configured instead of silently falling through. Using
'required' without tools is a logical contradiction — the model
must invoke a tool but none exist — so surfacing this as a
ValueError helps callers catch the misconfiguration early.
3. Update the corresponding test to expect ValueError instead of
silently omitted toolConfig.

longer in available_modes and resets to the default mode (matching the
non-string recovery branch). Added regression coverage for both behaviors.

* update hyperlight to beta and move samples, add hosted agent sample
* Python: Fix hyperlight WasmSandbox cross-thread Drop and harden sample
Root cause: when a worker-side closure raised, the exception's __traceback__
retained frame locals that included the partially constructed PyO3 sandbox.
Future.result() re-raised that exception on the caller thread, and when the
caller's exception was eventually GC'd the frame locals were released
off-thread, dec_ref'ing the unsendable sandbox from the wrong thread and
tripping the PyO3 panic
'_native_wasm::WasmSandbox is unsendable, but is being dropped on another thread'.
Fix:
* Add _SandboxWorker._run_on_worker which catches every exception on the
worker, drops __traceback__ there, deletes the original exception, and
re-raises a fresh instance on the caller thread. initialize and execute
route through it; dispose keeps its bare-submit semantics.
* Add an opt-in diagnostic module _drop_diagnostic (no-op unless
HYPERLIGHT_TRACE_DROPS=1) that installs a sys.unraisablehook and dumps
owner-thread + per-thread stacks on any future cross-thread unsendable
Drop. Useful for triaging similar PyO3 regressions.
* Tests: cross-thread invocation, traceback-leak isolation, _SandboxEntry
attribute-shape check, and a stale-reference stress test driven through
asyncio.to_thread.
Sample (samples/04-hosting/foundry-hosted-agents/responses/06_hyperlight_codeact):
* Dockerfile installs agent-framework-* from in-tree source with python/ as
build context so unreleased fixes can be validated end-to-end.
* call_server.py pins the Responses API version.
* main.py enables include_detailed_errors=True so future tool failures
surface the actual exception text instead of a bare 'Error: Function
failed.' string.
* README.md documents the in-tree-package build and the Hyperlight
hypervisor requirement (/dev/kvm on Linux, MSHV on Windows). Hosted
environments without hypervisor passthrough surface 'No Hypervisor was
found for Sandbox'; this is a hosting constraint, not a hyperlight bug.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Python: remove _drop_diagnostic from hyperlight package
The diagnostic module was useful while bisecting the cross-thread Drop bug,
but it is no longer needed now that _SandboxWorker._run_on_worker prevents
the panic at the source.

- Align agent.yaml model deployment with manifest (gpt-4.1-mini).
- Tighten Dockerfile requirements guard; drop dangling deploy.ps1 reference.
- Preserve exception args when sanitizing tracebacks in _run_on_worker.
- Add public _SandboxWorker.is_alive(); update test to avoid private attr.
- Add namespace coverage tests for agent_framework.hyperlight lazy loader.
- Add prominent note: Foundry hosted-agent runtime does not yet support
Hyperlight (no hypervisor exposed); container works locally with /dev/kvm.

- TodoFileStore now safely encodes session_id/owner and verifies path containment (matches FileHistoryProvider pattern)
- per-(session, source_id) asyncio.Lock around read-modify-write to avoid races

* Python: Core: rename TodoListContextProvider to TodoProvider
Match the .NET TodoProvider class name for cross-language consistency.
Other public types (TodoStore, TodoSessionStore, TodoFileStore,
TodoItem, TodoInput) are unchanged. Construction stays Pythonic
(kwargs, not an options object).

* Python: Core: address TodoProvider review feedback
- TodoStore.load_state/save_state are now async; TodoFileStore performs
disk I/O via asyncio.to_thread so the event loop is no longer blocked
while the per-session mutation lock is held.
- TodoSessionStore now raises ValueError for malformed top-level state
(non-dict / non-list 'items' / non-int 'next_id') to match the
TodoFileStore contract instead of silently re-defaulting.
- Both stores now clamp next_id to max(item.id) + 1 after load to make
ID collisions impossible after recovery or reconfiguration.
- TodoFileStore writes atomically by writing a sibling temp file and
os.replace-ing it so a crash mid-write cannot truncate the state file.
- TodoFileStore.load_state no longer creates parent directories for
sessions that never write; mkdir is deferred to save_state.
- TodoProvider mutation locks now live in a weakref.WeakKeyDictionary
keyed by AgentSession, so locks for GC'd sessions are evicted instead
of leaking in long-running services.
Tests cover each change including a TodoFileStore-backed end-to-end
provider flow, atomic-write recovery, and lock GC eviction.

* fix(devui): add created_at to custom output item events for correct workflow timings (#5545)
CustomResponseOutputItemAddedEvent and CustomResponseOutputItemDoneEvent lacked a
created_at field, causing the frontend to synthesize timestamps using integer-second
precision with a forced +1s minimum gap between events. This made instant workflows
appear to take 3+ seconds in the DevUI timeline.
Fix:
- Add optional created_at: float | None field to both custom event models
- Populate created_at=float(time.time()) in the mapper for executor_invoked,
executor_completed, and executor_failed events
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* fix(devui): use event created_at for accurate workflow timeline timings
workflow-view.tsx synthesized _uiTimestamp using Math.max(baseTimestamp,
lastTimestamp + 1) with integer-second precision, forcing a minimum 1-second
gap between every sequential event. This made instant workflows appear to take
several seconds in the DevUI timeline.
The fix prefers event.created_at (a float Unix timestamp populated by the
backend mapper for all executor events) and only falls back to the synthetic
timestamp when created_at is absent. This matches the pattern already used in
devuiStore.ts:addDebugEvent.
Added a regression test in test_mapper.py verifying that the mapper attaches
created_at to all executor lifecycle events (invoked, completed, failed).

* fix(devui): address review feedback for issue #5545
- Read data.timestamp (ISO string) and response.created_at in addition
to top-level created_at when deriving _uiTimestamp, so
response.workflow_event.completed events get a real server timestamp
instead of a synthesized one
- Change uniqueTimestamp tiebreaker: when a real server timestamp is
available use Math.max(eventTimestamp, lastTimestamp) rather than
lastTimestamp + 1, eliminating artificial 1-second gaps while still
preserving monotonic ordering
- Apply the same fix in the HIL streaming path (second setOpenAIEvents
call in workflow-view.tsx)
- Add assert event.created_at > 0 to regression test to guard against
zero or negative timestamps
- Add test_custom_output_item_event_models_have_created_at_field model-
level test so removing the field produces a clear named failure rather
than a downstream ValidationError

* fix(#5545): guard NaN timestamps, fix fallback ID uniqueness, add regression tests
- workflow-view.tsx (×2): Wrap data.timestamp ISO→number conversion in a
Number.isFinite() guard. Python's datetime.now().isoformat() emits
microseconds without a trailing 'Z' (e.g. '2024-01-15T12:34:56.123456'),
which some JS engines cannot parse, returning NaN. NaN !== undefined is
true so the eventTimestamp !== undefined guard did not catch it, poisoning
_uiTimestamp and resetting the monotonic ordering seed (NaN || 0 → 0).
- execution-timeline.tsx: Replace uiTimestamp in the fallback syntheticItemId
with the per-executor runNumber counter. Two runs of the same executor
within the same second previously received identical _uiTimestamp values
and therefore identical syntheticItemIds, causing their output buckets,
state, and run entries to collide (execution-timeline.tsx:360–408).
- Add missing test_workflow_timings_bug.py source file (only a stale .pyc
existed). Three regression tests:
· test_custom_event_models_lack_created_at_field – model field guard
· test_workflow_executor_events_lack_created_at – mapper populates created_at
· test_rapid_workflow_events_have_no_top_level_timestamps – confirms
data.timestamp format that requires the frontend NaN guard

* Address review feedback for #5545: Python: [Bug]: Workflow timings in DevUI are incorrect
* devui: move timing regression tests into test_mapper.py, remove dedicated bug file
- Delete test_workflow_timings_bug.py; tests belong in existing module files
- The two tests already present in test_mapper.py (test_executor_events_carry_created_at_timestamp
and test_custom_output_item_event_models_have_created_at_field) cover the same ground as the
first two tests in the deleted file
- Add test_executor_completed_maps_to_output_item_done_event to test_mapper.py, replacing the
third test from the deleted file with a generic, issue-agnostic name and docstring

Fixes#5394.
When `background=True` is combined with local function tools,
`FunctionInvocationLayer` calls `_inner_get_response(options=mutable_options)`
repeatedly with the same dict reference across loop iterations. Once the
first poll retrieves a completed background response, `continuation_token`
stays in `mutable_options`, so every subsequent iteration takes the
`continuation_token is not None` branch and `GET`s the same completed
response instead of `POST`ing the tool results. The loop exits after
`max_iterations` with empty text and the model never sees any tool output.
After the retrieve, if the returned `ChatResponse.continuation_token` is
`None` (the background response is no longer in progress), pop
`continuation_token` and `background` from the shared options dict in
place. The next loop iteration then falls through to the normal
`responses.create`/`parse` path and posts tool results.
The diagnosis and a verified runtime monkeypatch are in the issue; this
is the same fix moved in-tree.

* Python: Support GPT-5 verbosity option and restore Foundry agent_reference
Adds verbosity as a typed Literal["low","medium","high"] field on
OpenAIChatOptions (Responses API) and OpenAIChatCompletionOptions (Chat
Completions API), set in the same way as the existing reasoning options.
For the Responses API, top-level verbosity is translated to the nested
text.verbosity shape the OpenAI service expects. The same field flows
through to FoundryChatClient via the existing FoundryChatOptions alias.
Also fixes#5582: PR #5447 removed the agent_reference injection from
RawFoundryAgentChatClient._prepare_options, so first-turn calls against
a Foundry Prompt Agent went out without model and without agent_reference
and were rejected by the Responses API with "Missing required parameter:
'model'". Restores the injection on the non-preview path
(allow_preview=False) and adds a guard test that asserts the preview
path does not inject agent_reference, since the preview SDK injects it
via project_client.get_openai_client(agent_name=...).
Closes#5516Closes#5582
* Python: Address Copilot review on PR #5619
- Foundry verbosity sample docstring: replace the misleading "set deployment
name on model=" instruction with the actual env-var pattern the sample relies
on (FOUNDRY_PROJECT_ENDPOINT and FOUNDRY_MODEL).
- _build_agent_reference docstring: clarify the helper is used for both
Prompt Agents and HostedAgents on the non-preview path.
- Add a Responses API test that locks in the documented precedence rule:
when both top-level verbosity and text["verbosity"] are supplied, the
top-level value wins.
* Python: Drop redundant Foundry verbosity sample and list OpenAI sample in README
- Remove samples/02-agents/providers/foundry/foundry_chat_client_verbosity.py
per review feedback. The verbosity functionality is identical across the
OpenAI and Foundry clients (FoundryChatOptions is an alias of
OpenAIChatOptions), so a single sample on the OpenAI side is sufficient.
- Add the new client_verbosity.py entry to the OpenAI samples README.
* Python: Core: add experimental memory harness context provider
Adds MemoryContextProvider with topic-indexed long-term memory and
chat-driven compaction. Pluggable MemoryStore backends include
MemoryFileStore. Public types: MemoryIndexEntry, MemoryTopicRecord.
Behind @experimental(ExperimentalFeature.HARNESS).

* Python: Core: address review feedback on memory harness
- mark MemoryStore as @experimental(HARNESS) for surface consistency
- safely encode owner id and verify path containment (matches FileHistoryProvider pattern)
- namespace MemoryFileStore on-disk layout by source_id to avoid cross-provider collisions
- before_run computes index_entries once and only rewrites MEMORY.md when content changes
- asyncio locks around topic/state read-modify-write to avoid concurrent-write races
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Address PR feedback: harden memory store IO + consolidation behavior
- Atomic writes via os.replace + temp sibling for topic, state, and index files so
crashes/disk-full failures cannot leave a truncated half-written file.
- Stop creating directories on read paths: list_topics/read_state/search_transcripts
and get_messages return empty when nothing has been written. mkdir is deferred to
the actual save path (write_topic/write_state/save_messages).
- Escape lines that look like markdown headings on render and unescape them on parse,
so a memory or summary containing '## Summary'/'## Memories' cannot tamper with the
topic file structure.
- Narrow extraction/consolidation chat-client failure handling to ChatClientException,
asyncio.TimeoutError, and OSError. Programmer errors (AttributeError, TypeError, ...)
now propagate so misconfigured clients fail loudly.
- Log a payload-prefix preview for every silent shape branch in _extract_memories and
_consolidate_topic so unparsable extractor output is debuggable instead of invisible.
- Restructure _run_consolidation: read maintenance state and topic snapshot under the
state lock, run the LLM consolidation loop without holding the state lock, and only
advance last_consolidated_at/sessions_since_consolidation if at least one topic
succeeded. Transient consolidation failures now leave the maintenance window in
place so the next after_run retries instead of silently sliding forward.
- Add regression tests for: markdown-marker round-trip, atomic-write recovery on
os.replace failure, no-mkdir on pure read paths, transient consolidation failure
preserves state, and propagation of programmer errors.

The @ai_function decorator was renamed to @tool in release
python-1.0.0b260128 (PR #3413) as a breaking change.
Line 58 of python/samples/03-workflows/README.md still referenced
the old @ai_function name, causing users to hit:
ImportError: cannot import name 'AIFunction'
Changes made:
- Fixed @ai_function to @tool on line 58 only
- No formatting or whitespace changes
* docs(samples): recommend uv venv to avoid Windows ensurepip hang
Replace bare 'python -m venv .venv' with 'uv venv .venv' as the
recommended approach in azure_functions and foundry-hosted-agents
READMEs. Add a note explaining that python -m venv can hang
indefinitely on Windows with Microsoft Store Python due to a known
ensurepip issue.
This matches the pattern already used in a2a/README.md which uses
uv run exclusively.
