Python: Fix RUN_FINISHED.interrupt to accumulate all interrupts when multiple tools need approval (#4717 )

* Fix flow.interrupts overwrite when multiple tools need approval (#4590)

Change flow.interrupts assignment to append so that all interrupt entries
accumulate when multiple tools require approval in a single turn.

Both _run_common.py and _agent_run.py used assignment (=) which caused
each new interrupt to overwrite the previous one. Switching to append()
ensures RUN_FINISHED.interrupt contains all pending approvals.

* Add test for streaming path with multiple confirm_changes interrupts (#4590)

Also confirms FlowState already declares interrupts field with
default_factory=list, addressing the AttributeError concern from review.

The integration test asserts that WorkflowOutputEvent is found in the

only emitted via explicit YieldOutputAsync calls, the assertion would
fail. Added YieldOutputAsync to each executor to match the test
expectation and demonstrate the API in the sample.

Python: Fix _deduplicate_messages catch-all branch dropping valid repeated messages (#4716 )

* Fix _deduplicate_messages catch-all branch dropping valid repeated messages (#4682)

Remove the catch-all dedup branch that used (role, hash(content_str)) as a
dedup key. This incorrectly treated any two messages with the same role and
identical content as duplicates, dropping valid repeated messages (e.g., a
user saying 'yes' to confirm two separate things).

The tool-specific dedup branches (tool results by call_id, assistant tool
calls by call_id tuple) remain unchanged as they correctly identify true
protocol-level duplicates.

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

* Address review: consecutive-duplicate detection for non-tool messages (#4682)

- Replace blanket dedup removal with consecutive-duplicate detection:
  only skip a message if the immediately preceding message has the same
  role and content, preserving protection against upstream replays while
  allowing identical messages at different conversation points.
- Strengthen test assertions to verify message identity and order, not
  just list length.
- Add tests for consecutive duplicate skipping, non-consecutive
  preservation, and messages with contents=None.

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

* Apply pre-commit auto-fixes

* Use message_id for deduplication instead of content hashing

Deduplicate general messages by message_id when available, replacing
the consecutive-duplicate content check. Two messages with the same id
are definitively the same message (upstream replay), while identical
content with distinct ids (e.g. repeated "yes" confirmations) is
preserved. Messages without a message_id are always kept.

* Fix message_id dedup: truthy check, content-hash fallback, log safety

- Use truthy check (`if msg.message_id`) instead of `is not None` so
  empty-string IDs fall through to content-hash dedup rather than
  collapsing unrelated messages.
- Add content-hash fallback for messages without message_id, preventing
  false negatives from integrations that don't set IDs.
- Remove raw message_id from log format string (addresses log-injection
  surface with control characters).
- Add tests for empty-string message_id edge cases.
- Update existing tests to reflect content-hash dedup behavior.

[BREAKING] Python: clean up kwargs across agents, chat clients, tools, and sessions (#4581 )

* Python: clean up kwargs across agents, chat clients, tools, and sessions (#3642)

Audit and refactor public **kwargs usage across core agents, chat clients,
tools, sessions, and provider packages per the migration strategy codified
in CODING_STANDARD.md.

Key changes:
- Add explicit runtime buckets: function_invocation_kwargs and client_kwargs
  on RawAgent.run() and chat client get_response() layers.
- Refactor FunctionTool to prefer explicit ctx: FunctionInvocationContext
  injection; legacy **kwargs tools still work via _forward_runtime_kwargs.
- Refactor Agent.as_tool() to use direct JSON schema, always-streaming
  wrapper, approval_mode parameter, and UserInputRequiredException
  propagation (integrates PR #4568 behavior).
- Remove implicit session bleeding into FunctionInvocationContext; tools
  that need a session must receive it via function_invocation_kwargs.
- Lower chat-client layers after FunctionInvocationLayer accept only
  compatibility **kwargs (client_kwargs flattened, function_invocation_kwargs
  ignored).
- Add layered docstring composition from Raw... implementations via
  _docstrings.py helper.
- Clean up provider constructors to use explicit additional_properties.
- Deprecation warnings on legacy direct kwargs paths.
- Update samples, tests, and typing across all 23 packages.

Python: A2AAgent defaults name/description from AgentCard (#4661 )

* Python: A2AAgent defaults name/description from AgentCard

When an AgentCard is provided but name/description are not explicitly
set, A2AAgent now falls back to agent_card.name and agent_card.description.
This avoids redundant duplication when constructing A2AAgent instances,
especially in GroupChat orchestrations where name and description are
essential for routing decisions.

Explicit values still take precedence over card values.

Fixes #4630

fix: omit toolConfig when tool_choice="none" in BedrockChatClient (#4535 )

Bedrock's Converse API only accepts "auto", "any", or "tool" as valid
toolChoice keys. The previous code mapped tool_choice="none" to
{"none": {}}, which causes a botocore.exceptions.ParamValidationError.

When tool_choice="none" (set by FunctionInvocationLayer after exhausting
max iterations), the fix now omits toolConfig entirely so the model
won't attempt tool calls.

Added tests for tool_choice="none", "auto", and "required" modes.

Fixes #4529

Python: Fix state snapshot to use deepcopy so nested mutations are detected in durable workflow activities (#4518 )

* Use deepcopy for state snapshot to detect nested mutations (#4500)

Replace dict() shallow copy with copy.deepcopy() when snapshotting
workflow state before activity execution. The shallow copy shared
references to nested objects (dicts, lists), so in-place mutations by
executors were reflected in both the snapshot and live state, producing
an empty diff and preventing state updates from propagating to
downstream activities.

  production _create_state_snapshot helper creates a true deep copy

These tests ensure a regression back to shallow copy would be caught.

Fix CWE-863: Validate function approval responses in DevUI executor (#4598 )

The DevUI /v1/responses endpoint accepts function_approval_response content
without verifying that the request_id corresponds to a real pending approval
request issued by the server. This allows forged approval responses to
execute arbitrary tools with attacker-controlled arguments, bypassing
approval_mode='always_require'.

Changes:
- Track outgoing approval requests in a server-side registry
  (_pending_approvals) keyed by request_id
- Validate incoming approval responses against this registry; reject
  any response whose request_id was not issued by the server
- Use server-stored function_call data (tool name, arguments, call_id)
  instead of client-supplied data when constructing the approval response
- Consume request_ids on use (pop from registry) to prevent replay attacks

Tests:
- 8 new tests covering forged rejection, server-data enforcement,
  anti-replay, multiple independent approvals, and edge cases

* Validate approval responses against server-side pending request registry

* Pin CHCP sdk to LKG.

* really fix GHCP sdk pkg version

* Fix HITL approval validation security gaps and memory leak

- Validate rejected approval responses against pending_approvals registry,
  not just approved ones. Fabricated rejections without a prior request are
  now stripped from messages before reaching the LLM.
- Bound _pending_approvals with OrderedDict + LRU eviction (max 10k) to
  prevent unbounded memory growth from abandoned approval requests.
- Skip registration when function_call.name is None/empty; log warning
  when content.id or function_call is missing at registration time.
- Document pending_approvals parameter in run_agent_stream docstring.
- Add test for fabricated rejection attack scenario.
- Assert pending approval entry is preserved after function name mismatch.
- Pre-populate pending_approvals in rejection test for correct validation.

Python: Fix function_approval_response extraction in AG-UI workflow path (#4550 )

* Extract function_approval_response from workflow messages (#4546)

_extract_responses_from_messages now handles function_approval_response
content in addition to function_result content. Previously, approval
responses sent via the messages field were silently dropped because the
function only checked for content.type == "function_result".

The approval response is keyed by content.id and includes the approved
status, id, and serialized function_call — consistent with how
_coerce_content identifies approval response payloads.

Python: Fix executor_completed event with non-copyable raw_representation in mixed workflows (#4493 )

* Python: Fix `executor_completed` event with non-copyable raw_representation in mixed workflows

Fixes #4455

* fix(#4455): use class-level sets for deepcopy field exclusion

- SerializationMixin.__deepcopy__: check type(self).DEFAULT_EXCLUDE
  instead of hardcoding 'raw_representation'
- Content.__deepcopy__: add _SHALLOW_COPY_FIELDS class variable and
  check against it instead of hardcoding
- Fix tautological assertion in test (was always True)
- Add second excluded field to test to verify DEFAULT_EXCLUDE is
  respected generically

* Decouple __deepcopy__ from DEFAULT_EXCLUDE in SerializationMixin (#4455)

Introduce _SHALLOW_COPY_FIELDS class variable in SerializationMixin to
separate deep-copy semantics from serialization semantics. Previously,
__deepcopy__ used DEFAULT_EXCLUDE to decide which fields to shallow-copy,
conflating 'not serialized' with 'not safe to deep-copy'. A field added
to DEFAULT_EXCLUDE purely for serialization (e.g. additional_properties)
would be silently shared between original and copy.

- Add _SHALLOW_COPY_FIELDS (default {'raw_representation'}) to
  SerializationMixin, matching the pattern already used by Content
- Update __deepcopy__ to read from _SHALLOW_COPY_FIELDS instead of
  DEFAULT_EXCLUDE
- Add test verifying DEFAULT_EXCLUDE fields are deep-copied unless
  also in _SHALLOW_COPY_FIELDS
- Add test for Content._SHALLOW_COPY_FIELDS identity preservation
- Add test for ChatResponse deep-copying additional_properties

* Add test for _SHALLOW_COPY_FIELDS and DEFAULT_EXCLUDE independence

Add test_deepcopy_shallow_copy_fields_override_default_exclude to verify
that a field in both DEFAULT_EXCLUDE and _SHALLOW_COPY_FIELDS is
shallow-copied (controlled by _SHALLOW_COPY_FIELDS), while a field in
DEFAULT_EXCLUDE only is still deep-copied. This addresses review comment
#11 ensuring the two class variables control independent concerns.

* Remove unnecessary local variable in __deepcopy__

Inline cls._SHALLOW_COPY_FIELDS directly in the loop check instead of
assigning to a local variable first, per review feedback.
