Initialize _event_queue to None and create it on first use in _get_event_queue, mirroring the per-executor lock. Avoids constructing a queue in __init__/reset_for_new_run that is immediately discarded once the running loop is known.
Like the per-executor lock, the runner context's asyncio.Queue bound to the first event loop it was awaited under, so reusing a workflow across loops (e.g. successive asyncio.run calls) raised 'bound to a different event loop'. Re-create the queue lazily via _get_event_queue() when the running loop changes. Adds an integration test reusing a workflow across event loops.
asyncio.Lock created in Executor.__init__ would bind to the first event loop it was awaited under, so reusing an executor/workflow across loops (e.g. successive asyncio.run calls) raised 'bound to a different event loop'. Create the lock lazily via _get_execution_lock(), re-creating it when the running loop changes. Adds a loop-scoped lock test.
Add a per-executor asyncio.Lock in Executor.execute so each executor processes its messages one at a time within a superstep, while preserving concurrency across distinct executors. Includes a regression test.
* Refactor runner/workflow responsibilities, add concurrency guards, and fix checkpoint ancestry bug
Move runner-state ownership out of Workflow into Runner for clearer responsibilities. Add a weakref-based concurrent-run guard in Workflow and fix the stream-drop race in run_until_convergence. Fix the checkpoint ancestry bug by tracking the previous checkpoint id as runner instance state so parent pointers persist across resumed runs. Move Runner to a deprecated lazy __getattr__ export (backward-compatible with DeprecationWarning) and export CheckpointID.
* Scope runtime checkpoint storage to its owning run
Close the stream-drop race where a dropped run's deferred async-generator finalizer could leave a runtime checkpoint storage override set (inherited by a new run) or clear a successor run's storage. run() now defensively clears any stale override before starting, and _run_core only clears the override if this run still owns it (mirroring the _active_run ownership guard). Adds regression tests for both the inheritance and clobber cases.
* Collapse runtime-storage ownership into the active-run weakref
_runtime_storage_owner always held the same weakref as _active_run, so the two ownership conditions were equivalent. Derive ownership from a single owns_run = (_active_run is my_active_run) captured before the active-run clear, and remove the redundant field. No behavior change.
* Nest runtime-storage clear under the owns_run guard
Both the active-run release and the runtime-storage clear are gated on owns_run, so fold the storage clear inside the if owns_run block. No behavior change.
* Reset resume flag in a finally so it can't leak across runs
_resumed_from_checkpoint was only cleared on the success path of run_until_convergence, so a failure during a resumed run (e.g. executor failure) left it True. The next fresh run then skipped the superstep-0 checkpoint and parented later checkpoints to the stale resume point. Move the reset into a finally. Add a regression test that fails a resumed run via an executor error and asserts the next fresh run creates the superstep-0 checkpoint.

* Python: Address Telegram channel CI failures and review feedback
- Fix webhook secret validation to use constant-time compare_digest
- Harden webhook update parsing: require integer chat IDs and guard slash-only commands
- Fix streaming edge cases in TelegramChannel:
- prevent edit worker deadlocks when text exceeds 4096 chars
- prevent deadlock when placeholder send fails (message_id stays None)
- enforce edit throttling with minimum interval sleep
- honor send_typing_action=False in streaming mode
- always forward final multimodal output (e.g. images), while avoiding duplicate text sends
- Expand Telegram tests for slash-only command handling, non-int chat IDs, and streaming behavior (long text, final images, typing toggle)
- Fix sample/docs feedback:
- rename sample package to agent-framework-hosting-sample-local-telegram
- switch sample uv.sources from feature branch to main
- align docs/tool names with lookup_weather
- fix broken links and server run instructions in README/call_server.py

* Python: Split local_telegram into simple Telegram-only and new multi-channel sample
local_telegram is now a focused Telegram-only sample:
- Removes ResponsesChannel and all responses_hook code
- Removes call_server.py (no HTTP endpoint to call)
- Uses a deterministic lookup_weather tool (hash-based, not random)
- Single run_hook that strips model and raises reasoning effort
- Drops agent-framework-hosting-responses dependency
New local_multi_channel sample shows running both channels at once:
- ResponsesChannel + TelegramChannel sharing a FileHistoryProvider
- Cross-channel session resumption via previous_response_id
- call_server.py moved here (the Responses endpoint lives here now)
- Demonstrates the multi-channel coordination story
Update README table to list both samples with clear descriptions.
Also delete personal_assistant/.venv which was not tracked but caused
pyright to crawl the entire installed venv (thousands of files),
making sample pyright checks hang indefinitely.

* Python: [Breaking] Refactor FileSkillsSource for depth-based discovery and predicate filters
Refactors FileSkillsSource to make script and resource discovery more flexible.
## Changes
- **Drops** resource_directories / script_directories options (preconfigured
directory whitelists).
- **Adds** search_depth option (>= 1, default 2): controls how deep the
recursive scan goes within each skill directory.
- **Adds** script_filter / resource_filter predicate options that receive a
FileSkillFilterContext (skill_name + relative_file_path), allowing
whitelist/blacklist filtering by file path.
- **Adds** FileSkillFilterContext class exported from agent_framework.
## Notes
- The Skills API is marked @experimental -- the option removals are intentional
breaking changes within the experimental surface.
- Security checks (path containment, symlink detection) are preserved and
continue to use the skill root directory as the trusted boundary.
- Ports the same refactoring from .NET PR #6109 while following Python
conventions (instance methods, Callable type hints, __slots__).

* Address PR feedback: clarify depth constants and skip nested skill directories
- Add clarifying comments distinguishing MAX_SEARCH_DEPTH (SKILL.md

preventing child skill files from being attached to the parent skill.
- Add test verifying nested skill boundary is respected.

- Update docstrings to describe behavior instead of referencing private
instance attributes.
- Remove FileSkillFilterContext from exports and __all__.

* .NET: Fix hosted agent crash after tool call by rooting session store under $HOME
FileSystemAgentSessionStore.CreateDefault rooted the hosted session store at the
filesystem root "/.checkpoints", which is read-only inside a Foundry hosted
container. After a local tool call the response handler persists the session, so
the write to "/.checkpoints" threw IOException and tore down the container, which
the platform surfaced as "mount: /app: mount failed: No such file or directory.".
Root the hosted store at $HOME (default /home/session), the only writable and
durable location per the container image spec. Persistence failures stay fatal but
are now wrapped in a clear, actionable IOException instead of the opaque raw error.
Add unit tests covering hosted and local path resolution plus the clear error, and
enable the ToolCalling Foundry Hosted Agents integration tests (verified live).
Fixes#6231
* .NET: Harden hosted session store against a filesystem-root HOME
Address review feedback on #6714: a misconfigured HOME pointing at a filesystem
root (e.g. "/") resolved back to "/.checkpoints" and would reintroduce the original
read-only-root crash. CreateDefault now falls back to the default session-data
directory (/home/session) when HOME is missing, blank, a filesystem root, or an
unnormalizable path. Adds a unit test locking in the "never the filesystem root"
behavior for a hosted HOME of "/".

Skill content now always emits <available_resources> and <available_scripts>
blocks, using self-closing elements when empty, so models receive an
authoritative list per category and do not hallucinate resource/script names.
FileSkill now also emits its resources block.

* .NET Foundry: add CreateMcpTool projectConnectionId overload
Adds FoundryAITool.CreateMcpTool(serverLabel, serverUri, projectConnectionId, ...)
so hosted MCP tools can authenticate through a Foundry project connection, matching
the Python FoundryChatClient.get_mcp_tool(..., project_connection_id=...) factory.
The connection id is applied via the McpTool.ProjectConnectionId extension that ships
in Azure.AI.Projects.Agents (patches project_connection_id), already referenced by the
Foundry package. Includes unit tests and sample/README guidance plus the existing
FromResponseTool workaround.
* Fold projectConnectionId into existing CreateMcpTool overload
Replaces the separate project-connection overload with an optional
projectConnectionId parameter on the existing serverUri CreateMcpTool, so all
settings (authorizationToken, headers, allowedTools, ...) stay available and there
is no positional overload ambiguity. Adds tests for the default (no connection)
path and for preserving other settings. Sample/README now show only the supported
overload.
* NET: Support archive-type skills in AgentMcpSkillsSource

unpacks, and serves packaged skills through an internal file skills
source, while ensuring MCP-delivered scripts are never executed.

* fix: propagate skill script/resource exceptions instead of swallowing them

* Add sample for per-run refreshable MCP authentication headers
Adds a Foundry RAPI sample that attaches per-run, refreshable authentication headers to MCP requests using existing primitives: a DelegatingHandler on the MCP transport's HttpClient plus an AsyncLocal run scope. The same agent runs under two contexts, each minting a fresh token, proving the header is per run rather than bound at agent or connection creation time.
The handler attaches the bearer only over HTTPS to the MCP server's own origin, logs the non-secret label only, disables cookies, and checks certificate revocation. The README covers security considerations and production notes.
Fixes#1631
* Address PR review: harden redirect handling, nest-safe scope, README env vars
Disable AllowAutoRedirect on the shared handler so a redirect cannot carry the bearer past the origin check. Save and restore the prior run scope instead of clearing to null so the helper is safe under nesting.

OpenTelemetryAgent auto-wired OpenTelemetryChatClient above FICC, producing
OTel(FICC(leaf)). FICC resolved its ActivitySource at construction time as null,
so execute_tool spans were never emitted for tool-calling agents.
This repositions OTel below FICC, producing FICC(OTel(leaf)), via a deferred
NoOp slot pre-placed as the innermost decorator in WithDefaultAgentMiddleware
and activated once at the agent level.
- Add internal DeferredOpenTelemetryChatClient: inert DelegatingChatClient whose
Activate(sourceName) swaps its target to inner.AsBuilder().UseOpenTelemetry().Build().
- WithDefaultAgentMiddleware always registers the slot innermost so it lands below FICC.
- OpenTelemetryAgent activates the slot once in its constructor and forwards run
options straight through, removing the per-run ChatClientFactory outer wrap.
- Add and update unit tests, including a proof that execute_tool spans are emitted
on the agent source and parented under invoke_agent.
