  • Python: Add Cosmos DB NoSQL Checkpoint Storage for Python Workflows (#4916)
    * Add CosmosCheckpointStorage for Python workflow checkpointing
    
    Add native Cosmos DB NoSQL support for workflow checkpoint storage in the
    Python agent-framework-azure-cosmos package, achieving parity with the
    existing .NET CosmosCheckpointStore.
    
    New files:
    - _checkpoint_storage.py: CosmosCheckpointStorage implementing the
      CheckpointStorage protocol with 6 methods (save, load, list_checkpoints,
      delete, get_latest, list_checkpoint_ids)
    - test_cosmos_checkpoint_storage.py: Unit and integration tests
    - workflow_checkpointing.py: Sample demonstrating Cosmos DB-backed
      workflow checkpoint/resume
    
    Auth support:
    - Managed identity / RBAC via Azure credential objects
      (DefaultAzureCredential, ManagedIdentityCredential, etc.)
    - Key-based auth via account key string or AZURE_COSMOS_KEY env var
    - Pre-created CosmosClient or ContainerProxy
    
    Key design decisions:
    - Partition key: /workflow_name for efficient per-workflow queries
    - Serialization: Reuses encode/decode_checkpoint_value for full Python
      object fidelity (hybrid JSON + pickle approach)
    - Container auto-creation via create_container_if_not_exists

    * fix: resolve mypy redundant-cast errors while keeping pyright happy
    
    Use cast(list[Any], x) with type: ignore[redundant-cast] comments to
    satisfy both mypy (which considers casting Any redundant) and pyright
    strict mode (which needs explicit casts to narrow Unknown types).
    
    Also fix evaluator decorator check_name type annotation to be
    explicitly str, resolving mypy str|Any|None mismatch.

    * fix: skip gRPC-dependent observability test
    
    The test_configure_otel_providers_with_env_file_and_vs_code_port test
    triggers gRPC OTLP exporter creation, but the grpc dependency is
    optional and not installed by default. Add skipif decorator matching
    the pattern used by all other gRPC exporter tests in the same file.

    * Remove core type changes (extracted to fix/workflow-stale-session branch)
    
    Reverts changes to _agents.py, _agent_executor.py, and _workflow.py
    back to upstream/main. These fixes are now in a separate PR.

    * Address PR review round 2: bugs, tests, and architecture
    
    Code fixes:
    - Fix _normalize_queries inverted condition (single query now replicates
      to match expected_count)
    - Fix substring match bug: 'end' in 'backend' matched; use exact set
      lookup for executor ID filtering
    - Fix used_available_tools sample: tool_definitions→tools param, use
      FunctionTool attribute access instead of dict .get()
    - Add None-check in _resolve_openai_client for misconfigured project
    - Add Returns section to evaluate_workflow docstring
    - Cache inspect.signature in @evaluator wrapper (avoid per-item reflection)
    
    Architecture:
    - Extract _evaluate_via_responses as module-level helper; evaluate_traces
      now calls it directly instead of creating a FoundryEvals instance
    - Move Foundry-specific typed-content conversion out of core to_eval_data;
      core now returns plain role/content dicts, FoundryEvals applies
      AgentEvalConverter in _evaluate_via_dataset
    
    Tests:
    - evaluate_response() deprecation warning emission and delegation
    - num_repetitions > 1 with expected_output and expected_tool_calls
    - Mock output_items.list in test_evaluate_calls_evals_api
    - Update to_eval_data assertions for plain-dict format
    - Unknown param error now raised at @evaluator decoration time
    
    Skipped (separate PR): executor reset loop, xfail removal, options alias

    * Fix CI: revert test_full_conversation, fix pyright errors
    
    - Revert test_full_conversation.py to upstream/main (the session
      preservation test was incorrectly changed to assert clearing)
    - Fix pyright reportUnnecessaryComparison on get_openai_client() None
      check by adding ignore comment
    - Fix pyright reportPrivateUsage: add public EvalItem.split_messages()
      method and use it in FoundryEvals._evaluate_via_dataset instead of
      accessing private _split_conversation

    * Address PR review round 3: reliability, test gaps, cleanup
    
    - Add try/except guard for non-numeric score in _coerce_result
    - Add poll_interval minimum bound (0.1s) to prevent tight loops
    - Add runtime async client check in _resolve_openai_client
    - Remove _ensure_async_result wrapper (10 call sites → direct await)
    - Better error message when queries provided without agent
    - Import-time asserts for evaluator set consistency
    - Remove 28 redundant @pytest.mark.asyncio decorators
    - Add doc note about _raw_arguments sensitive data
    - Tests: tool_called_check mode=any, _normalize_queries branches,
      _extract_result_counts paths, _extract_per_evaluator, bare check
      via evaluate_agent, output_items assertion, modulo wrapping,
      async client check, queries-without-agent error

    * Fix CI: ruff S101 assert, pyright and mypy arg-type errors
    
    - Replace module-level assert with if/raise for evaluator set
      consistency checks (ruff S101 disallows bare assert)
    - Add type: ignore[arg-type] and pyright: ignore[reportArgumentType]
      on OpenAI SDK evals API calls that pass dicts where typed params
      are expected (SDK accepts dicts at runtime)

    * Address PR review round 4: bugs, reliability, test fixes
    
    - Fix all_passed ignoring parent result_counts when sub_results present
    - Fix _extract_tool_calls: parse string arguments via json.loads before
      falling back to None (real LLM responses use string arguments)
    - Sanitize _raw_arguments to '[unparseable]' to avoid leaking sensitive
      tool-call data to external evaluation services
    - Add NOTE comment on to_eval_data message serialization dropping
      non-text content (tool calls, results)
    - Eliminate double conversation split in _evaluate_via_dataset: build
      JSONL dicts directly from split_messages + AgentEvalConverter
    - Raise poll_interval floor from 0.1s to 1.0s to prevent rate-limit
      exhaustion
    - Fix MagicMock(name=...) bug in test: sets display name not .name attr
    - Fix mock_output_item.sample: use MagicMock object instead of dict so
      _fetch_output_items exercises error/usage/input/output extraction

    * Address PR review round 5: reliability, docs, test coverage
    
    Code fixes:
    - Move import-time RuntimeError checks to unit tests (avoids breaking
      imports for all users on developer set-drift mistake)
    - _filter_tool_evaluators now raises ValueError when all evaluators
      require tools but no items have tools (was silently substituting)
    - Add poll_interval upper bound (60s) to prevent single-iteration sleep
    - Log exc_info=True in _fetch_output_items for debugging API changes
    - Fix evaluate() docstring: remove claim about Responses API optimization
    - Validate target dict has 'type' key in evaluate_foundry_target
    - Document to_eval_data() limitation: non-text content is omitted
    
    Tests:
    - TestEvaluatorSetConsistency: verify _AGENT/_TOOL subsets of _BUILTIN
    - TestEvaluateTracesAgentId: agent_id-only path with lookback_hours
    - TestFilterToolEvaluatorsRaises: ValueError on all-tool no-items
    - TestEvaluateFoundryTargetValidation: target without 'type' key
    - Assert items==[] on failed/canceled poll results
    - Mock output_items.list in response_ids test for full flow
    - TestAllPassedSubResults: result_counts=None + sub_results delegation
      and parent failures override sub_results
    - TestBuildOverallItemEmpty: empty workflow outputs returns None
    
    Skipped r5-07 (_raw_arguments length hint): marginal debugging value,
    could leak content size information.

    * Fix error message: evaluate_responses() → evaluate_traces(response_ids=...)
    
    The referenced function doesn't exist; the correct API is
    evaluate_traces(response_ids=...) from the azure-ai package.

    * Remove dead to_eval_data() method, fix docstring claims
    
    - Remove to_eval_data() from EvalItem (dead code after r4-05 JSONL refactor)
    - Migrate 15 tests from to_eval_data() to split_messages()
    - Update sample to use split_messages() + Message properties
    - Remove unimplemented Responses API optimization docstring claim
    - Update split_messages() docstring to not reference removed method

    * Remove dead _evaluate_via_responses method from FoundryEvals
    
    The method was never called — evaluate() uses _evaluate_via_dataset,
    and evaluate_traces() calls _evaluate_via_responses_impl directly.

    * Fix eval samples: use FoundryChatClient for Agent()
    
    The upstream provider-leading client refactor (#4818) made client=
    a required parameter on Agent(). Update the three getting-started
    eval samples to use FoundryChatClient with FOUNDRY_PROJECT_ENDPOINT,
    matching the standard pattern from 01-get-started samples.

    * Simplify self-reflection sample using FoundryEvals
    
    Replace ~80 lines of manual OpenAI evals API code (create_eval,
    run_eval, manual polling, raw JSONL params) with FoundryEvals:
    
    - evaluate_groundedness() uses FoundryEvals.evaluate() with EvalItem
    - Remove create_openai_client(), create_eval(), run_eval() functions
    - Remove openai SDK type imports (DataSourceConfigCustom, etc.)
    - run_self_reflection_batch creates FoundryEvals instance once,
      reuses it for all iterations across all prompts

    * Update eval samples to FoundryChatClient and FOUNDRY_PROJECT_ENDPOINT
    
    - Migrate all foundry_evals samples from AzureOpenAIResponsesClient to FoundryChatClient
    - Update env var from AZURE_AI_PROJECT_ENDPOINT to FOUNDRY_PROJECT_ENDPOINT
    - Use AzureCliCredential consistently across all samples
    - Fix README.md: correct function names (evaluate_dataset -> FoundryEvals.evaluate, evaluate_responses -> evaluate_traces)
    - Update self_reflection .env.example and README.md

    * Fix async credential mismatch: use azure.identity.aio for async AIProjectClient
    
    AIProjectClient from azure.ai.projects.aio requires an async credential.
    Switch all foundry_evals samples from azure.identity.AzureCliCredential
    to azure.identity.aio.AzureCliCredential. Also pass project_client to
    FoundryChatClient instead of duplicating endpoint+credential.
    
    Close credential in self_reflection sample to avoid resource leak.

    * Address moonbox3 review: sphinx docstrings, pagination, isinstance check
    
    - Convert all Example:: / Typical usage:: code blocks to .. code-block:: python
      format matching codebase convention (both _evaluation.py and _foundry_evals.py)
    - Add async pagination in _fetch_output_items via async for (handles large result sets)
    - Replace hasattr(__aenter__) with isinstance(client, AsyncOpenAI) in _resolve_openai_client
    - Move AsyncOpenAI import from TYPE_CHECKING to runtime (needed for isinstance)
    
    Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
    
    * Fix test failures and address remaining moonbox3 review comments
    
    - Fix tests: use MagicMock(spec=AsyncOpenAI) for project_client mocks
      (isinstance check now requires proper type, not duck-typing)
    - Fix tests: replace mock_page.__iter__ with _AsyncPage helper for async for
    - Fix evaluate_response: auto-extract queries from response messages when
      query is not provided (previously always raised ValueError)
    - Add debug logging when skipping internal _-prefixed executor IDs

    * Address Tao's PR review comments on Foundry Evals
    
    - T1: Add comment explaining builtin.* pass-through in _resolve_evaluator
    - T2: Add comment referencing OpenAI evals API for testing_criteria dict
    - T3: Document Mustache-style {{item.*}} template placeholders
    - T4: Document poll loop 60s sleep upper bound rationale
    - T5: Narrow run type to RunRetrieveResponse, use typed field access
      instead of vars()/getattr dance in _extract_result_counts and
      _extract_per_evaluator; use run.error and run.report_url directly
    - T6: Clarify openai_client docstring re: Azure Foundry endpoint
    - T8: Remove misleading empty expected_tool_calls from sample
    - Update tests to match real SDK PerTestingCriteriaResult shape

    * Remove unnecessary Any union from run type annotations
    
    RunRetrieveResponse is the correct type — no backward compat needed
    for a brand new feature.

    * Accept FoundryChatClient instead of raw AsyncOpenAI
    
    FoundryEvals now takes client: FoundryChatClient as its primary
    parameter instead of openai_client: AsyncOpenAI.  The builtin.*
    evaluators require a Foundry endpoint, so the type should reflect that.
    
    - FoundryEvals.__init__: client: FoundryChatClient replaces openai_client
    - evaluate_traces / evaluate_foundry_target: same change
    - _resolve_openai_client: extracts .client from FoundryChatClient
    - project_client fallback retained for standalone functions
    - All samples updated to construct FoundryChatClient and pass as client=
    - Tests updated (openai_client= → client=)

    * Remove implicit 60s upper bound on poll interval
    
    If a developer sets a higher poll_interval, respect it. Only clamp
    to remaining time and enforce a 1s minimum for rate-limit protection.

    * Replace ConversationSplitter type alias with Protocol
    
    ConversationSplitter is now a runtime-checkable Protocol with a named
    'conversation' parameter, making the expected signature self-documenting.
    
    ConversationSplit enum members gain a __call__ method so they satisfy
    the protocol directly -- ConversationSplit.LAST_TURN(conversation) works.
    
    This simplifies _split_conversation from an isinstance dispatch to a
    single split(conversation) call.

  • Python: fix reasoning model workflow handoff and history serialization (#4083)
    * fix: strip function_call and text_reasoning from cross-agent workflow handoff
    
    When a reasoning model (e.g. gpt-5-mini) runs as Agent 1 in a workflow, its
    response includes text_reasoning items (with server-scoped IDs like rs_XXXX)
    and function_call items. Forwarding these to Agent 2 in a fresh conversation
    caused API errors because the reasoning/call IDs are scoped to the original
    stored response context.
    
    Changes:
    - Strip 'function_call', 'text_reasoning', 'function_approval_request', and
      'function_approval_response' from handoff messages in _agent_executor.py
    - Keep 'function_result' so the actual tool output content is preserved for
      the next agent's context
    - Update unit tests to reflect that function_result messages survive handoff
      (messages grow from 2→3: user, tool(result), assistant(summary))
    - Fix incorrect test assertions in test_function_invocation_stop_clears_*
      that assumed the client layer updates session.service_session_id
    - Also fixed _extract_function_calls to search all messages with call_id
      deduplication, and the error-limit stop path to submit function_call_output
      items before halting (via tool_choice=none cleanup call)
    
    Relates to: https://github.com/microsoft/agent-framework/issues/4047

    * fix: reasoning model workflow handoff and history serialization
    
    Fixes multiple related issues when using reasoning models (gpt-5-mini,
    gpt-5.2) in multi-agent workflows that chain agents via from_response
    or replay full conversation history via AgentExecutorRequest.
    
    ## Reasoning items always emitted on output_item.added
    
    When a reasoning model produces encrypted or hidden reasoning (no
    visible text), the Responses API still fires a reasoning output item
    without any reasoning_text.delta events. Previously no text_reasoning
    Content was emitted in that case, making it invisible to downstream
    logic. Both the non-streaming (_parse_response_from_openai) and
    streaming (output_item.added) paths now always emit at least one
    text_reasoning Content — with empty text if no content is available —
    so co-occurrence detection and serialization guards work reliably.
    
    ## Reasoning items only serialized when paired with a function_call
    
    The Responses API only accepts reasoning items in input when they
    directly preceded a function_call in the original response. Sending a
    reasoning item that preceded a text response (no tool call) causes:
      "reasoning was provided without its required following item"
    _prepare_message_for_openai now checks has_function_call per message
    and skips text_reasoning serialization when there is no accompanying
    function_call.
    
    ## summary field is an array, not an object
    
    The reasoning item summary field sent to the Responses API must be an
    array of objects ([{"type": "summary_text", "text": ...}]), not a
    single object. Fixed _prepare_content_for_openai accordingly.
    
    ## service_session_id cleared when explicit history is provided
    
    When a workflow coordinator replays a full conversation (including
    function calls from a previous agent run) back to an executor via
    AgentExecutorRequest or from_response, the executor's session still
    held a service_session_id (previous_response_id) from the prior run.
    The API then received the same function-call items twice — once from
    previous_response_id (server-stored) and once from the explicit input —
    causing: "Duplicate item found with id fc_...".
    
    AgentExecutor.run (when should_respond=True) and from_response now
    reset self._session.service_session_id = None before running so that
    explicit input is the sole source of conversation context.

    * small improvements in text reasoning
    
    * refactor: add reset_service_session to AgentExecutorRequest for explicit history replay
    
    Replace the implicit 'always clear service_session_id when should_respond=True'
    with an explicit opt-in field on AgentExecutorRequest.
    
    The old approach used should_respond=True as a proxy for 'full history replay',
    but that conflates two distinct intents:
    - Orchestrations group chat sends should_respond=True with an empty/single-message
      list (not a full replay) — unnecessarily clearing service_session_id.
    - HITL / feedback coordinators send the full prior conversation and truly need
      a fresh service session ID to avoid duplicate-item API errors.
    
    Changes:
    - Add AgentExecutorRequest.reset_service_session: bool = False
    - AgentExecutor.run only clears service_session_id when this flag is True
    - AgentExecutor.from_response unchanged (always clears; always full conversation)
    - Set reset_service_session=True in all full-history-replay call sites:
      agents_with_HITL.py, azure_chat_agents_tool_calls_with_feedback.py,
      autogen-migration round-robin coordinator, tau2 runner
    - Update _FullHistoryReplayCoordinator test helper to pass the flag

  • Python: Fix streamed workflow agent continuation context by finalizing AgentExecutor streams (#3882)
    * Fix streamed workflow agent continuation context by finalizing AgentExecutor streams
    
    * Fix stream handling
    
    * Fixes
    
    * Fix DevUI and tests
  • Python: [BREAKING] PR2 — Wire context provider pipeline, remove old types, update all consumers (#3850)
    * PR2: Wire context provider pipeline and update all internal consumers
    
    - Replace AgentThread with AgentSession across all packages
    - Replace ContextProvider with BaseContextProvider across all packages
    - Replace context_provider param with context_providers (Sequence)
    - Replace thread= with session= in run() signatures
    - Replace get_new_thread() with create_session()
    - Add get_session(service_session_id) to agent interface
    - DurableAgentThread -> DurableAgentSession
    - Remove _notify_thread_of_new_messages from WorkflowAgent
    - Wire before_run/after_run context provider pipeline in RawAgent
    - Auto-inject InMemoryHistoryProvider when no providers configured
    
    * fix: update all tests for context provider pipeline, fix lazy-loaders, remove old test files
    
    * refactor: update all sample files for context provider pipeline (AgentThread→AgentSession, ContextProvider→BaseContextProvider)
    
    * fix: update remaining ag-ui references (client docstring, getting_started sample)
    
    * fix: make get_session service_session_id keyword-only to avoid confusion with session_id
    
    * refactor: rename _RunContext.thread_messages to session_messages
    
    * refactor: remove _threads.py, _memory.py, and old provider files; migrate devui to use plain message lists
    
    * rename: remove _new_ prefix from test files
    
    * refactor: rewrite SlidingWindowChatMessageStore as SlidingWindowHistoryProvider(InMemoryHistoryProvider)
    
    * fix: read full history from session state directly instead of reaching into provider internals
    
    * fix: update stale .pyi stubs, sample imports, and README references for new provider types
    
    * fix: remove stale message_store, _notify_thread_of_new_messages, and session_id.key references in samples
    
    * refactor: merge context_providers and sessions sample folders into sessions, remove aggregate_context_provider
    
    * refactor: UserInfoMemory stores state in session.state instead of instance attributes
    
    * feat: add Pydantic BaseModel support to session state serialization
    
    Pydantic models stored in session.state are now automatically serialized
    via model_dump() and restored via model_validate() during to_dict()/from_dict()
    round-trips. Models are auto-registered on first serialization; use
    register_state_type() for cold-start deserialization.
    
    Also export register_state_type as a public API.
    
    * fix mem0
    
    * Update sample README links and descriptions for session terminology
    
    - Replace 'thread' with 'session' in sample descriptions across all READMEs
    - Update file links for renamed samples (mem0_sessions, redis_sessions, etc.)
    - Fix Threads section → Sessions section in main samples/README.md
    - Update tools, middleware, workflows, durabletask, azure_functions READMEs
    - Update architecture diagrams in concepts/tools/README.md
    - Update migration guides (autogen, semantic-kernel)
    
    * Fix broken Redis README link to renamed sample
    
    * Fix Mem0 OSS client search: pass scoping params as direct kwargs
    
    AsyncMemory (OSS) expects user_id/agent_id/run_id as direct kwargs,
    while AsyncMemoryClient (Platform) expects them in a filters dict.
    Adds tests for both client types.
    
    Port of fix from #3844 to new Mem0ContextProvider.
    
    * Fix rebase issues: restore missing _conversation_state.py and checkpoint decode logic
    
    - Add back _conversation_state.py (encode/decode_chat_messages) lost in rebase
    - Fix on_checkpoint_restore to decode cache/conversation with decode_chat_messages
    - Fix on_checkpoint_restore to use decode_checkpoint_value for pending requests
    - Add tests/workflow/__init__.py for relative import support
    - Fix test_agent_executor checkpoint selection (checkpoints[1] not superstep)
    
    * Add STORES_BY_DEFAULT ClassVar to skip redundant InMemoryHistoryProvider injection
    
    Chat clients that store history server-side by default (OpenAI Responses API,
    Azure AI Agent) now declare STORES_BY_DEFAULT = True. The agent checks this
    during auto-injection and skips InMemoryHistoryProvider unless the user
    explicitly sets store=False.
    
    * Fix broken markdown links in azure_ai and redis READMEs
    
    * Fix getting-started samples to use session API instead of removed thread/ContextProvider API
    
    * updates to workflow as agent
    
    * fix group chat import
    
    * Rename Thread→Session throughout, fix service_session_id propagation, remove stale AGUIThread
    
    - Fix: Propagate conversation_id from ChatResponse back to session.service_session_id
      in both streaming and non-streaming paths in _agents.py
    - Rename AgentThreadException → AgentSessionException
    - Remove stale AGUIThread from ag_ui lazy-loader
    - Rename use_service_thread → use_service_session in ag-ui package
    - Rename test functions from *_thread_* to *_session_*
    - Rename sample files from *_thread* to *_session*
    - Update docstrings and comments: thread → session
    - Update _mcp.py kwargs filter: add 'session' alongside 'thread'
    - Fix ContinuationToken docstring example: thread=thread → session=session
    - Fix _clients.py docstring: 'Agent threads' → 'Agent sessions'
    
    * Fix broken markdown links after thread→session file renames
    
    * fix azure ai test
  • Python: restructure: Python samples into progressive 01-05 layout (#3862)
    * restructure: Python samples into progressive 01-05 layout
    
    - 01-get-started/: 6 numbered steps (hello agent → hosting)
    - 02-agents/: all agent concept samples (tools, middleware, providers, etc.)
    - 03-workflows/: ALL existing workflow samples preserved as-is
    - 04-hosting/: azure-functions, durabletask, a2a
    - 05-end-to-end/: demos, evaluation, hosted agents
    - Old files moved to _to_delete/ for review
    - Added AGENTS.md with structure documentation
    - autogen-migration/ and semantic-kernel-migration/ preserved at root
    
    * fix: switch to AzureOpenAI Foundry, fix CI failures
    
    - Switch all 01-get-started samples to AzureOpenAIResponsesClient with
      Azure AI Foundry project endpoint (AZURE_AI_PROJECT_ENDPOINT +
      AZURE_OPENAI_RESPONSES_DEPLOYMENT_NAME + AzureCliCredential)
    - Add _to_delete/ and 05-end-to-end/ to pyrightconfig.samples.json excludes
    - Fix test paths in packages/ that referenced old getting_started/ dirs:
      durabletask conftest + streaming test, azurefunctions conftest,
      devui conftest + capture_messages + openai_sdk_integration
    - Fix workflow_as_agent_human_in_the_loop.py import (sibling import)
    - Update hosting READMEs and tool comment paths
    - Replace root README.md with new structure overview
    - Update AGENTS.md to document Azure OpenAI Foundry as default provider
    
    * cleanup: remove _to_delete folder, copy resource files to active dirs
    
    All files in _to_delete/ were either:
    - Exact duplicates of files in the new structure (240 files)
    - Same file with only comment path updates (100 files)
    - One import-fix diff (workflow_as_agent_human_in_the_loop.py)
    - One superseded minimal_sample.py
    
    Resource files (sample.pdf, countries.json, employees.pdf, weather.json)
    copied to 02-agents/sample_assets/ and 02-agents/resources/ since active
    samples reference them.
    
    * fix: address PR review comments, centralize resources, remove root duplicates
    
    - Fix type annotation in 04_memory.py (string union -> proper types)
    - Fix old sample paths in observability files
    - Fix grammar/spelling in observability samples
    - Move sample_assets/ and resources/ to shared/ folder
    - Remove 8 duplicate observability files from 02-agents root
    - Update resource path references in multimodal_input and provider samples
    
    * fix: update broken links from old getting_started paths to new structure
    
    - Update relative paths in READMEs: getting_started/ → 01-get-started/,
      02-agents/, 03-workflows/, 04-hosting/, 05-end-to-end/
    - Fix absolute GitHub URLs in package READMEs
    - Fix broken link in ollama package README
    
    * fix: convert absolute GitHub URLs to relative paths for link checker
    
    Absolute URLs to python/samples/ on main branch 404 until PR merges.
    Converted to relative paths that linkspector can verify locally.
    
    * fix: update link for handoff sample moved to orchestrations/
    
    * fix: update chatkit-integration README path from demos/ to 05-end-to-end/
    
    * fix: update broken links in orchestrations README to match flat directory structure
