SelectorGroupChat.load_state() appends to the selector's model context instead of overwriting it (duplicate/stale history on rollback)

### Description `BaseGroupChat.load_state()` is documented to *overwrite* the current state. Participant agents get that semantics: their `ChatCompletionContext.load_state()` replaces the whole context. The selector group chat manager, however, **appends** to its...

test_source_prompt_requirements_resolves_the_name_like_load_prompt fails with sqlite 'unable to open database file'

...failed with sqlite3.OperationalError (unable to open database file) on /tmp/tmpq9i5pncm/mlflow.db. The test uses no store fixture, but since #27230 _source_prompt_requirements calls _stored_registered_model_name, which hits the global model registry store. That store points at a...

[BUG] A failed task can be skipped after checkpoint restore because its output remains set

### Description When a task produces an output but its `output_file` write fails, `TaskFailedEvent` is emitted while `Task.output` remains populated. If checkpointing is triggered by `task_failed`, the checkpoint stores that output even though the task did not emit...

[Bug]: MCP tool discovery ignores pages after nextCursor

### Bug Description `BasicMCPClient.list_tools()` and `McpToolSpec.fetch_tools()` consume only the first `tools/list` response. If a server returns `nextCursor`, later tools never reach the agent. An `allowed_tools` filter selecting a tool on the second page consequently returns...

[BUG] Guardrail retry drops the context of the previously-successful upstream task that the retried task depends on

### Description I have a crew with two tasks, each run by its own agent: - `research_task` (researcher agent) successfully outputs the account facts, including the service code `ACCT-8841`. - - `case_note_task` (writer agent) depends on that output (context=[research_task]), has...

Python: Bug: AnnotationContent and StreamingAnnotationContent to_element writes CitationType.X, so annotations in a rendered chat history fail to parse

### Describe the bug `AnnotationContent.to_element()` and `StreamingAnnotationContent.to_element()` store the `CitationType` enum object in the XML attribute: `CitationType` is a `str, Enum`. When the element is serialized, the attribute is written with the enum's `str()` form,...

## Description `AsyncFileStream` is included in `FileSource` and is documented for async handles such as `aiofiles` objects. However, passing one to `TextFile` or `ImageFile` raises a validation error before it can reach `FileResolver.aresolve()`. This prevents a caller with an...
