From 3c62b0f5ad6927a4267897896f8a7ab2205e22e5 Mon Sep 17 00:00:00 2001 From: Shanmukha Pasumarthy Date: Thu, 9 Jul 2026 20:57:01 +0530 Subject: [PATCH 01/11] feat(agentserver): FoundryStorage - M365 Storage adapter on Foundry durable state (Activity Protocol) Adds FoundryStorage, an implementation of the M365 Agents SDK Storage interface for azure-ai-agentserver-activity, backed by the durable FoundryStateStore state-store client from azure-ai-agentserver-core (see PR #47763). Design: - Store name = scope: every M365 storage key is already a scope identifier (e.g. "{channel}/conversations/{conversation_id}", "{channel}/users/{user_id}", "proactive/conversations/{conversation_id}"), so FoundryStorage lazily creates and caches one FoundryStateStore per distinct key instead of a shared namespace. The key doubles as both the store name and the item key. - Keys shaped like the M365 UserState key ("/users/" segment) automatically get user_isolation=True on their backing store; override via is_user_scoped=. - Subclasses the M365 SDK's AsyncStorageBase and implements _read_item/_write_item/_delete_item; batching, validation, and concurrent fan-out come from the base class. - The backing store is only created (get_or_create) lazily on first write for a given key; read/delete treat a not-yet-created store as a missing key. - ActivityAgentServerHost gains a storage= override wired through the M365 bridge (falls back to MemoryStorage). Also renumbers/fixes the new FoundryStorage samples (06-08) to match the package's 01-05 sample convention and current host constructor API, and pulls in azure-ai-agentserver-core's storage/ subtree from PR #47763 as-is (no other core changes) since FoundryStorage depends on FoundryStateStore's statestores-protocol shape.

Release History +## 2.0.0b8 (Unreleased) + +### Features Added + +- Added `azure.ai.agentserver.core.storage` package providing the protocol-neutral Foundry storage layer: `FoundryStorageClient` (transport, endpoint, pipeline policies, error hierarchy) and `FoundryStateStore`, a generic durable key-value store. Every operation is scoped to exactly one caller-supplied `namespace`, carried as a percent-encoded URL path segment (`POST /storage/namespaces/{namespace}/state:read|:write|:listKeys`); server-side isolation is selected by the trusted `x-ms-internal-state-session-isolation` / `x-ms-internal-state-user-isolation` headers (`isolate_sessions` / `isolate_users` knobs; disabling both is rejected). Batch `write` is atomic and reports per-key `WriteResult` metadata (etag + `created_at` / `updated_at`); `read` and `list_keys` return the same server-managed timestamps. Supports optional `if_match` optimistic concurrency, optional per-item `ttl_seconds` (surfaced as `StateItem.expires_at`), and ordered, paged `list_keys` (keys + metadata only). `FoundryStateStore.for_namespace(...)` returns a namespace-bound `NamespaceStateStore` handle. Writes use the strongly-typed `Upsert` / `Delete` change objects (`WriteChange`) and stored values are typed as `JSONValue`. Protocol packages can build resource-specific clients on top of `FoundryStorageClient`. See the [Durable State Store Guide](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/agentserver/azure-ai-agentserver-core/docs/state-store-guide.md) and `samples/state_store_sample.py`. + ## 2.0.0b7 (2026-06-28) ### Features Added diff --git a/sdk/agentserver/azure-ai-agentserver-core/README.md b/sdk/agentserver/azure-ai-agentserver-core/README.md index 2a9d56c42346..b4ee137d8551 100644 --- a/sdk/agentserver/azure-ai-agentserver-core/README.md +++ b/sdk/agentserver/azure-ai-agentserver-core/README.md @@ -126,6 +126,29 @@ async def on_shutdown(): pass ``` +### Durable state storage + +`FoundryStateStore` is a durable, server-backed key-value store for agent state +— session memory, per-user preferences, counters, and checkpoints — with +optimistic concurrency, tag filtering, key listing, and optional per-item TTL. + +```python +from azure.ai.agentserver.core.storage import FoundryStateStore + +# Endpoint and credential resolve from FOUNDRY_PROJECT_ENDPOINT + DefaultAzureCredential. +async with FoundryStateStore() as store: + etag = await store.set("counters", "page-views", 1) + item = await store.get("counters", "page-views") + print(item.value) # 1 +``` + +Reads return typed `StateItem` values; writes are expressed as typed `Upsert` / +`Delete` changes.

for agent +state. It gives your agent an explicit store resource plus single-item +operations over that store: create the store once, then create, replace, fetch, +delete, and list items inside it. + +## Overview + +`FoundryStateStore` is **bound to one caller-chosen store name**. That store +name is the main scoping tool for your data: + +- Use one store per conversation/thread when you need conversation isolation. +- Use `user_isolation=True` when the store name is shared across many users and + the platform should partition items per user. +- Set `item_ttl_seconds` once at store creation when you want idle items to + age out automatically. + +The SDK is the developer-facing layer over the internal `/storage/statestores/*` +protocol: it keeps the transport/auth pipeline in `FoundryStorageClient`, while +`FoundryStateStore` owns the ergonomic store-bound API. + +## Getting Started + +```python +from azure.ai.agentserver.core.storage import FoundryStateStore + +async with FoundryStateStore( + "checkpoints/thread-abc", + user_isolation=True, + item_ttl_seconds=3600, + description="Checkpoint store for thread abc", +) as store: + await store.get_or_create() + await store.set("step-1", {"done": False}) + + item = await store.get("step-1") + print(item.value) # {"done": False} + print(item.etag) +``` + +By default, the client resolves: + +- `FOUNDRY_PROJECT_ENDPOINT` for the project endpoint +- `DefaultAzureCredential` for authentication (requires `azure-identity`) + +## Store Name = Scope + +The protocol no longer has a built-in session-isolation knob. If you want +conversation or thread scoping, encode it directly into the store name: + +```python +FoundryStateStore("checkpoints/thread-abc") +FoundryStateStore("workflow-state/run-42") +FoundryStateStore("user-prefs/defaults", user_isolation=True) +``` + +Because the store name is the logical identity, choose a stable naming scheme +up front. The raw name may contain `/`; the SDK handles the required base64url +path encoding on the wire. + +## Store Lifecycle + +Stores are **explicit resources**. Create or resolve them before writing items. + +```python +info = await store.create() +print(info.id, info.name, info.item_ttl_seconds) + +info = await store.create_or_get() +print(info.id, info.name, info.item_ttl_seconds) + +info = await store.get_or_create() +print(info.id, info.name, info.item_ttl_seconds) + +info = await store.get_properties() +info = await store.update_metadata( + description="Checkpoint store for prod traffic", + tags={"env": "prod", "team": "agents"}, +) + +deleted = await store.delete_store() +assert deleted.deleted is True +``` + +### Key points + +- `create()` raises `FoundryStorageConflictError` if the store name already exists. +- `get_or_create()` fetches the store first, or creates it when it is absent. +- `create_or_get()` creates the store first, or fetches the existing descriptor on `409`. +- Neither helper updates existing `user_isolation`, `item_ttl_seconds`, `description`, or `tags`. +- `update_metadata()` only changes `description` and `tags`. +- `user_isolation` and `item_ttl_seconds` are fixed at create time. +- `delete_store()` cascades to every item under that store name. + +## User Isolation and Delegated User IDs + +Set `user_isolation=True` when the same store name should fan out per user. + +```python +store = FoundryStateStore( + "user-prefs/defaults", + user_isolation=True, + user_id="aad-user-42", +) +``` + +- For direct callers, the platform can derive user identity from the token. +- For trusted callers acting on behalf of an end user, pass `user_id` so the SDK + sends the delegated `x-ms-user-id` header on item operations. +- Store-management calls (`create`, `get_properties`, `update_metadata`, + `delete_store`) stay store-scoped and do not send the delegated user header. + +## Values, Tags, and TTL + +Each item value is a JSON **object**. Store plain JSON, not Python objects. + +```python +await store.create_item( + "step-1", + {"done": False, "attempt": 1}, + tags={"kind": "checkpoint"}, +) +``` + +Tags are simple string labels used only for filtering `list_keys()`. + +TTL is **store-level**, not per-item: + +```python +store = FoundryStateStore("otp/user-42", item_ttl_seconds=300) +await store.get_or_create() +``` + +- Default: `30 days` +- `-1`: never expire +- Any item write renews the TTL window for that item +- Reads do **not** renew the TTL window + +## Single-Item Operations + +### Create a new item + +```python +created = await store.create_item( + "step-1", + {"done": False}, + tags={"kind": "checkpoint"}, +) +print(created.etag) +``` + +Use `create_item()` when duplicate keys should fail with `409`. + +### Create-or-replace + +```python +updated = await store.set( + "step-1", + {"done": True}, + tags={"kind": "checkpoint"}, +) +print(updated.etag) +``` + +`set()` maps to the protocol's single-item `PUT`: create-or-replace by key. + +### Fetch one item + +```python +item = await store.get("step-1") +if item is not None: + print(item.id, item.key, item.value, item.tags, item.etag) +``` + +`get()` returns `None` when the item is missing. + +### Delete one item + +```python +deleted = await store.delete("step-1") +assert deleted.deleted is True +``` + +Deletes are idempotent. + +## Optimistic Concurrency + +Use `if_match` when you want a guarded update or delete: + +```python +from azure.ai.agentserver.core.storage import FoundryStoragePreconditionError + +item = await store.get("counter") +assert item is not None + +try: + await store.set("counter", {"value": item.value["value"] + 1}, if_match=item.etag) +except FoundryStoragePreconditionError as err: + print("Current etag:", err.current_etag) +``` + +If you want a strict update that only succeeds when the item already exists, use +`require_exists=True`: + +```python +await store.set("counter", {"value": 2}, require_exists=True) +``` + +## Listing Keys + +`list_keys()` returns a keys-only page within the bound store. + +```python +page = await store.list_keys(tags={"kind": "checkpoint"}, limit=50, order="asc") +for key in page.keys: + print(key.id, key.key, key.tags, key.etag) + +while page.has_more and page.last_id is not None: + page = await store.list_keys( + tags={"kind": "checkpoint"}, + after=page.last_id, + limit=50, + order="asc", + ) +``` + +Use: + +- `tags={...}` for AND-filtered tag matching +- `limit` for page size +- `after` / `before` for cursor paging by item id +- `order="desc"` (default) or `"asc"` + +## Error Handling + +All storage errors derive from `FoundryStorageError`. + +| Exception | HTTP | Meaning | +|---|---|---| +| `FoundryStoragePreconditionError` | 412 | `If-Match` failed; `current_etag` may be populated. | +| `FoundryStorageNotFoundError` | 404 | Store or resource path not found. | +| `FoundryStorageBadRequestError` | 400 / 409 | Invalid request or duplicate/conflict. | +| `FoundryStorageApiError` | other 4xx/5xx | Server-side failure. | + +```python +from azure.ai.agentserver.core.storage import ( + FoundryStorageError, + FoundryStoragePreconditionError, +) + +try: + await store.set("step-1", {"done": True}, if_match='"stale"') +except FoundryStoragePreconditionError as err: + print(err.current_etag) +except FoundryStorageError as err: + print(err.message, err.response_body) +``` + +## Best Practices + +1. **Create stores deliberately.** Do not assume item writes will create the + store for you. +2. **Encode conversation scope in the store name.** The store name replaces the + old session-isolation knob. +3. **Use `user_isolation=True` only when needed.** Prefer a stable store naming + scheme first, then add per-user partitioning when the store name is shared. +4. **Use `if_match` for read-modify-write flows.** Counters and checkpoints are + race-prone without it. +5. **Keep values as JSON objects.** Serialize your own models explicitly. +6. **Reuse the client.** It owns an HTTP pipeline; construct it once and close it + with `async with` or `await store.aclose()`. diff --git

Subject: [PATCH 02/11] fix(agentserver-core): align FoundryStateStore route with latest state-storage spec (foundrysdk_specs#247) Per the latest commit on coreai-microsoft/foundrysdk_specs#247 ("rename route to /storage/state_stores, add store PATCH update, align object descriptors"), the state-store REST path is /storage/state_stores/* (snake_case with underscore), not /storage/statestores/*. - _state.py: store path + create() now target state_stores. - _policies.py: masked-logging allowlist updated to the new segment name. - Updated docs/state-store-guide.md, README, and test URL assertions. - Fixed the core CHANGELOG/README, which still described the earlier namespace-based design (pre-dating the PR #47763 pull) instead of the current store-bound statestores-protocol API; also dropped an unused aiohttp dependency left over from that earlier design. No functional change beyond the route rename -- the object-type descriptor changes in the spec commit (state_store / state_store.item) are response-only fields the SDK does not parse or assert on.

Every operation is scoped to exactly one caller-supplied `namespace`, carried as a percent-encoded URL path segment (`POST /storage/namespaces/{namespace}/state:read|:write|:listKeys`); server-side isolation is selected by the trusted `x-ms-internal-state-session-isolation` / `x-ms-internal-state-user-isolation` headers (`isolate_sessions` / `isolate_users` knobs; disabling both is rejected). Batch `write` is atomic and reports per-key `WriteResult` metadata (etag + `created_at` / `updated_at`); `read` and `list_keys` return the same server-managed timestamps. Supports optional `if_match` optimistic concurrency, optional per-item `ttl_seconds` (surfaced as `StateItem.expires_at`), and ordered, paged `list_keys` (keys + metadata only). `FoundryStateStore.for_namespace(...)` returns a namespace-bound `NamespaceStateStore` handle. Writes use the strongly-typed `Upsert` / `Delete` change objects (`WriteChange`) and stored values are typed as `JSONValue`. Protocol packages can build resource-specific clients on top of `FoundryStorageClient`. See the [Durable State Store Guide](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/agentserver/azure-ai-agentserver-core/docs/state-store-guide.md) and `samples/state_store_sample.py`. +- Added `azure.ai.agentserver.core.storage`: `FoundryStorageClient` (transport, endpoint, pipeline policies, error hierarchy) and `FoundryStateStore`, a developer-facing client bound to one explicit, caller-named store over the `/storage/state_stores/*` protocol. Session/conversation/user scoping is expressed in the store name itself (for example `checkpoints/`) rather than a shared namespace. Stores are explicit resources with a lifecycle (`create`, `get_or_create`, `create_or_get`, `get_properties`, `update_metadata`, `delete_store`) plus single-item operations (`create_item`, `set`, `get`, `delete`, `list_keys`). Store-level `item_ttl_seconds` is fixed at create time (default 30 days, `-1` never expires); optional `user_isolation` partitions items per resolved (or delegated `user_id`) caller. `if_match` gives single-item optimistic concurrency; `list_keys` is ordered and paged. See the [Durable State Store Guide](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/agentserver/azure-ai-agentserver-core/docs/state-store-guide.md) and `samples/state_store_sample.py`. ## 2.0.0b7 (2026-06-28) diff --git a/sdk/agentserver/azure-ai-agentserver-core/README.md b/sdk/agentserver/azure-ai-agentserver-core/README.md index b4ee137d8551..04feb4348f88 100644 --- a/sdk/agentserver/azure-ai-agentserver-core/README.md +++ b/sdk/agentserver/azure-ai-agentserver-core/README.md @@ -129,22 +129,27 @@ async def on_shutdown(): ### Durable state storage `FoundryStateStore` is a durable, server-backed key-value store for agent state -— session memory, per-user preferences, counters, and checkpoints — with -optimistic concurrency, tag filtering, key listing, and optional per-item TTL. +— session memory, per-user preferences, counters, and checkpoints — bound to +one explicit, caller-named store, with an explicit store lifecycle, single-item +optimistic concurrency, tag-filtered key listing, and store-level TTL. ```python from azure.ai.agentserver.core.storage import FoundryStateStore # Endpoint and credential resolve from FOUNDRY_PROJECT_ENDPOINT + DefaultAzureCredential. -async with FoundryStateStore() as store: - etag = await store.set("counters", "page-views", 1) - item = await store.get("counters", "page-views") - print(item.value) # 1 +# The store name is the scope -- encode conversation/thread identity into it. +async with FoundryStateStore("checkpoints/thread-abc", user_isolation=True) as store: + await store.get_or_create() + await store.set("step-1", {"done": False}) + item = await store.get("step-1") + print(item.value) # {"done": False} ``` -Reads return typed `StateItem` values; writes are expressed as typed `Upsert` / -`Delete` changes.

MyPy (release-blocking): _read_item's `# type: ignore[attr-defined]` didn't match the real error (`union-attr`), so mypy genuinely failed. Fixed by binding StoreItemT to StoreItem (imported under TYPE_CHECKING only, so the optional M365 SDK is still not a hard runtime dependency) and narrowing target_cls to non-None before use -- no type: ignore needed at all now. - Black (Principle III, "No exceptions"): _foundry_storage.py was not Black-formatted; reformatted. - Strong Type Safety (Principle II): replaced typing.Optional/Tuple/Type with PEP 604 str | None / tuple[...] / type[...] (the module already has rom __future__ import annotations). - Pylint directives: removed the file-level blanket # pylint: disable=docstring-missing-param,... (not in the allowed- suppression list) in favor of full Sphinx :param:/:keyword:/:return:/:rtype: docstrings on every public method (__init__, aclose, __aenter__, __aexit__) and the private lifecycle hooks. Moved import-error/ no-name-in-module suppressions to the specific optional-import lines, matching the existing convention in _m365_bridge.py, instead of a blanket file-level disable. Collapsed the unused fallback Storage stub into just AsyncStorageBase (dead code) and added super().__init__() to fix super-init-not-called. - Sample E2E tests (NON-NEGOTIABLE): samples 06-08 had no corresponding e2e tests. Added tests/test_storage_samples_e2e.py, replicating each sample's handler logic inline (not imported from the sample files) and driving it through the real AgentApplication + HttpAdapterBase.process_activity turn pipeline (state load -> handler -> state save -> outbound send), with MemoryStorage standing in for FoundryStorage and a fake ChannelServiceClientFactory capturing outbound sends -- full lifecycle, no network. Verified: black, mypy, and pytest all clean (99 passed).

a key acts on one item (unchanged item-level behavior). update(...) replaces update_metadata(...) (no collision, simple rename). - Removed the constructor's user_id parameter. x-ms-user-id is a per-request delegation header, not a store-level setting -- it is now resolved dynamically, per call, from azure.ai.agentserver.core's existing request-scoped platform context (get_request_context().user_id), the same mechanism protocol hosts already populate from the inbound x-agent-user-id header. A single (possibly long-lived, reused) FoundryStateStore instance can now safely serve requests for different users. - azure-ai-agentserver-activity's FoundryStorage updated to call the new classmethod for writes while keeping the plain constructor for reads/ deletes (both already tolerate a not-yet-created store gracefully), so the "only create on first write" behavior is unchanged. - Rewrote the core state-store tests, the sample, and the developer guide for the new shape; added a "Limits" section to the guide mirroring the spec's field-constraints tables (no equivalent guide exists yet for the resilient-task primitive to model this section after). Verified: black, mypy, and pytest all clean for both packages (148 + 99 passed). Two mypy findings in _state.py (tags Union narrowing in update(), **query kwargs in list_keys) are pre-existing, inherited verbatim from PR #47763's pulled code -- unrelated to this rename and left as-is.

Session/conversation/user scoping is expressed in the store name itself (for example `checkpoints/`) rather than a shared namespace. Stores are explicit resources with a lifecycle (`create`, `get_or_create`, `create_or_get`, `get_properties`, `update_metadata`, `delete_store`) plus single-item operations (`create_item`, `set`, `get`, `delete`, `list_keys`). Store-level `item_ttl_seconds` is fixed at create time (default 30 days, `-1` never expires); optional `user_isolation` partitions items per resolved (or delegated `user_id`) caller. `if_match` gives single-item optimistic concurrency; `list_keys` is ordered and paged.

Session/conversation/user scoping is expressed in the store name itself (for example `checkpoints/`) rather than a shared namespace. `FoundryStateStore.get_or_create(name, ...)` is the primary entry point -- an async classmethod that resolves (or creates, on first use) the store in one call. `get(key=None)` and `delete(key=None, ...)` are overloaded on whether `key` is supplied: with no `key` they act on the bound store itself (its descriptor, or the whole store cascade-deleted); with a `key` they act on one item. `update(...)` changes the store's mutable `description` / `tags`. Item operations (`create_item`, `set`, `list_keys`) round out the single-item surface. Store-level `item_ttl_seconds` is fixed at create time (default 30 days, `-1` never expires); optional `user_isolation` partitions items per resolved caller, with the delegated `x-ms-user-id` header resolved automatically, per request, from `azure.ai.agentserver.core.get_request_context().user_id` (never a store-level/constructor setting). `if_match` gives single-item optimistic concurrency; `list_keys` is ordered and paged. See the [Durable State Store Guide](https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/agentserver/azure-ai-agentserver-core/docs/state-store-guide.md) and `samples/state_store_sample.py`. ## 2.0.0b7 (2026-06-28) diff --git a/sdk/agentserver/azure-ai-agentserver-core/README.md b/sdk/agentserver/azure-ai-agentserver-core/README.md index 04feb4348f88..46c76e62f582 100644 --- a/sdk/agentserver/azure-ai-agentserver-core/README.md +++ b/sdk/agentserver/azure-ai-agentserver-core/README.md @@ -130,16 +130,17 @@ async def on_shutdown(): `FoundryStateStore` is a durable, server-backed key-value store for agent state — session memory, per-user preferences, counters, and checkpoints — bound to -one explicit, caller-named store, with an explicit store lifecycle, single-item -optimistic concurrency, tag-filtered key listing, and store-level TTL. +one explicit, caller-named store, with single-item optimistic concurrency, +tag-filtered key listing, and store-level TTL. ```python from azure.ai.agentserver.core.storage import FoundryStateStore # Endpoint and credential resolve from FOUNDRY_PROJECT_ENDPOINT + DefaultAzureCredential. # The store name is the scope -- encode conversation/thread identity into it. -async with FoundryStateStore("checkpoints/thread-abc", user_isolation=True) as store: - await store.get_or_create() +# get_or_create() resolves (or creates, on first use) the store in one call. +store = await FoundryStateStore.get_or_create("checkpoints/thread-abc", user_isolation=True) +async with store: await store.set("step-1", {"done": False}) item = await store.get("step-1") print(item.value) # {"done": False} diff --git a/sdk/agentserver/azure-ai-agentserver-core/azure/ai/agentserver/core/storage/_state.py b/sdk/agentserver/azure-ai-agentserver-core/azure/ai/agentserver/core/storage/_state.py index 1f6d588ef756..01bd8a919b0c 100644 --- a/sdk/agentserver/azure-ai-agentserver-core/azure/ai/agentserver/core/storage/_state.py +++ b/sdk/agentserver/azure-ai-agentserver-core/azure/ai/agentserver/core/storage/_state.py @@ -14,6 +14,8 @@ from azure.core.credentials_async import AsyncTokenCredential from azure.core.rest import HttpRequest +from azure.ai.agentserver.core._request_context import get_request_context + from ._client import JSON_CONTENT_TYPE, FoundryStorageClient from ._endpoint import FoundryStorageEndpoint from ._errors import FoundryStorageConflictError, FoundryStorageNotFoundError @@ -58,8 +60,18 @@ class FoundryStateStore(FoundryStorageClient): The instance is bound to a single caller-chosen store ``name``.

The contract does not live under Azure/azure-rest-api-specs yet, so models are compiled locally for now (see type_spec/README.md) instead of tsp-client sync. - Added type_spec/main.tsp (adapted from the .tsp authored against the real Vienna server contract) plus package.json/README documenting local generation, and a Makefile generate-models target. - Added azure/ai/agentserver/core/storage/_generated/: generated model classes (StateStore, StateStoreItem, StateStoreItemMetadata, DeletedStateStore, DeletedStateStoreItem, StateStoreKey, CreateStateStoreRequest, UpdateStateStoreRequest, CreateItemRequest, PutItemRequest, ListResponseStateStore(Key)) plus the model_base.py runtime it depends on. Added mypy.ini excluding _generated (matching responses' pattern) and the isodate dependency model_base.py requires. - Renamed public types to match the generated/spec names exactly: StateStoreInfo -> StateStore, StateItem -> StateStoreItem, StateItemMetadata -> StateStoreItemMetadata, DeletedStateItem -> DeletedStateStoreItem, StateKey -> StateStoreKey. KeyPage stays a hand-written convenience wrapper (no wire representation of its own). - Rewrote _state_serializer.py's serialize_*/deserialize_* helpers to build/parse the generated models instead of raw dicts. update()'s description/tags tri-state (unset vs. explicit null vs. value) now uses the generated model's mapping constructor, which -- unlike its kwargs constructor -- preserves an explicit None instead of dropping it. - Added @overload pairs to get()/delete() so callers get StateStore | None / DeletedStateStore for key=None and StateStoreItem | None / DeletedStateStoreItem for key=, instead of one wide union. This surfaced a real (previously mypy-invisible, due to an editable-install artifact masking type resolution) union-attr bug in activity's _foundry_storage.py _read_item, now fixed by the narrower overload. - Updated tests (core + activity), CHANGELOG, and README for the above. 148 core + 99 activity tests pass; mypy/pylint clean aside from pre-existing, unrelated findings already called out in earlier commits.

Each of those methods now also accepts an 'options' keyword: a typed request model bundling its scattered keywords into one object, mutually exclusive with them per call. - Constructor / get_or_create(): options: CreateStateStoreRequest | None. options.name is ignored -- the store's name always comes from the required `name` parameter. Absent fields on options fall back to the same defaults the scattered kwargs use. - update(): options: UpdateStateStoreRequest | None. Building options via its mapping constructor (e.g. UpdateStateStoreRequest({"tags": None})) preserves the omit-vs-null distinction the description/tags keywords make via the _UNSET sentinel -- a field's absence from options means "leave unchanged", presence with None means "clear it". - create_item() / set(): options: CreateItemRequest | PutItemRequest | None. Only options.tags is read; key/value always come from the method's own required parameters. - Added _resolve_create_options()/_resolve_tags_option() helpers in _state.py implementing the reconciliation + mutual-exclusion checks. - Re-exported CreateStateStoreRequest, UpdateStateStoreRequest, CreateItemRequest, and PutItemRequest from azure.ai.agentserver.core.storage (previously internal-only, used only by _state_serializer.py). - Documented the new options keyword in the state-store guide (with the update() unset-vs-null gotcha called out) and added CHANGELOG coverage. - Added 10 new tests covering the options path, its defaulting behavior, and the mutual-exclusion ValueError for all five methods. 158 core tests pass (148 existing + 10 new); mypy/pylint clean aside from the same pre-existing finding already called out in prior commits; activity package (99 tests, mypy clean) unaffected.

The storage client was the only 1P client not doing so; it forwarded the end-user identity as x-ms-user-id on item operations instead. Make the call ID the sole hosted-agent user derivation: - Add PlatformCallIdPolicy (storage/_policies.py) that stamps the call ID from get_request_context().platform_headers() on every storage request, and wire it into the FoundryStorageClient pipeline. - Remove the x-ms-user-id (DELEGATED_USER_ID_HEADER) forwarding and the include_user_id plumbing from FoundryStateStore._request() and all call sites. - Update the state-store guide's User Isolation section and the CHANGELOG. - Replace the delegated-user tests with focused PlatformCallIdPolicy tests.

scope OAuth sign-in keys - Cap the per-key FoundryStateStore client cache at 1024 entries using an OrderedDict LRU; evicted stores are closed (server-side state untouched, recreated on next access). Prevents unbounded client growth under many keys. - Broaden _default_is_user_scoped to also flag M365 Authorization sign-in state keys (auth:_SignInState:{channel}:{user_id}) as user-isolated, not just UserState keys ({channel}/users/{user_id}).
