## Description
Adds docstring clarification that cron schedules are interpreted in UTC
for `CronClient.create`, `CronClient.create_for_thread`, and their sync
variants.
**Description:** The crons create endpoint supports an end-time field
that is not currently supported in the client. Adding that parameter
here.

bumping sdk-py for custom encryption cleanup changes (#6595) - these are
breaking changes on this beta, unreleased and unused feature.
Signed-off-by: Connor Braa <cwlbraa@langchain.dev>
In langgraph-api, custom-encrypted JSONs need to continue to be
SQL-json-mergable after encryption. Previous WIP docs
advocated for custom encryption impls where all encrypted kv pairs were
shoved into a `__encrypted__: $encrypted_kvs` meta-key. Turns out that
pattern causes data loss when running PATCH-style partial updates or in
the many places langgraph-api json-SQL-merges across model types.
This PR contains 2 SDK fixes:
1. remove model-type specific custom json encryption annotations - these
cause surprising behavior as config and context data propagates across
model types, specifically because today we can't guarantee that data
encrypted as one model-type will be decrypted as the same model-type
because kv pairs move across model-types in pure SQL
2. document limitations and validation around "key preservation" in
custom json encryption functions. langgraph-api now validates that
custom JSON encryption fns don't change keys. That validation prevents
customizers from writing custom encryption functions that cause data
loss through patch endpoints and x-model merge propagation.

- **Description:** Provide the id of the event for routes that use SSE
streams. This will allow for more custom retry logic when streams
disconnect if needed.

**Description**: The Agent Server API now supports counting assistants
by name.
This is similar to adding the `name` parameter to the Assistants search
API: https://github.com/langchain-ai/langgraph/pull/6483
**Description:**
This PR adds the Python SDK types necessary for langgraph platform users
to inject their own custom encryption-at-rest functions. See [docs
PR](https://github.com/langchain-ai/docs/pull/1715) for more details.
note: this PR adds a starlette dev dependency so that custom encryption
can access BaseUser information.
**Issue:**
required for LSD-172
**Dependencies:**
- [depended upon by associated langgraph-api
changes](https://github.com/langchain-ai/langgraph-api/pull/1773)(this
PR must merge before that one)
- [docs PR](https://github.com/langchain-ai/docs/pull/1715)
**TODO:**
- [x] move docs to docs repo
- [x] bump package versions before merge

**Description:** There are times a user might want to create the client,
but conditionally set the API key. For example, consider a complex auth
situation where the system has user callers using jwts and system
callers using API keys. This allows explicitly disabling the
auto-loading behavior of API keys in the client today, so no key is set.
**Issue:** N/A

## Description
- Fixed a bug in `libs/sdk-py/langgraph_sdk/auth/__init__.py` where the
error message for an already-set authentication handler did not properly
render the handler value.
- Updated the error string from a static `{self._authenticate_handler}`
to a correctly interpolated f-string.
```python
"Authentication handler already set as {self._authenticate_handler}."
```
```python
f"Authentication handler already set as {self._authenticate_handler}."
```
- Error messages now correctly display the actual handler instance,
improving debugging clarity.

- [x] **Add tests and docs**: If you're adding a new integration, you
must include:
1. A test for the integration, preferably unit tests that do not rely on
network access,
2. An example notebook showing its use. It lives in
`docs/docs/integrations` directory.
- [ ] **Lint and test**: Run `make format`, `make lint` and `make test`
from the root of the package(s) you've modified. We will not consider a
PR unless these three are passing in CI. See [contribution
guidelines](https://github.com/langchain-ai/langgraph/blob/main/CONTRIBUTING.md)
for more.
Additional guidelines:
- Make sure optional dependencies are imported within a function.
- Please do not add dependencies to `pyproject.toml` files (even
optional ones) unless they are **required** for unit tests.
- Most PRs should not touch more than one package.
- Changes should be backwards compatible.
Requests are not guaranteed to contain a body, and a request's body is
not guaranteed to be valid JSON.
This updates the type signature for authentication handlers
to account for these scenarios.
* catching error thrown by asyncio
* using 2nd check for annotations given Pydantic 2.12 changes
* skipping tests for remote graph bc langgraph-api is dependent on
`jsonschema-rs`
* skipping tests w/ pydantic v1 models
```bash
hint: This usually indicates a problem with the package or the build environment.
help: `jsonschema-rs` (v0.29.1) was included because `langgraph:dev` (v1.0.0rc1) depends on `langgraph-cli[inmem]` which
depends on `langgraph-api` (v0.4.29) which depends on `jsonschema-rs`
```
not yet testing for free threaded python, that'll be much more involved!
ended up separating lint / testing deps during this process bc I was
getting a ton of not required deps while testing that were complicating
things :/
some of these changes were obvious, and some were less obvious. In a few
spots, it felt like a judgement call if we should be saying LangSmith
Deployment of LangGraph Server. But hopefully either works.

The `$contains` auth operator supports subset containment checks, but
this has previously been undocumented. This updates `FilterType` and its
associated docstring to reflect this support.

## Summary
- add a public accessor for the last received SSE event id
- retry async and sync SSE streams using the Location reconnect path and
Last-Event-ID while skipping empty events
- add regression tests that simulate interrupted SSE streams for both
async and sync clients
## Testing
- make format
- make lint
- make test
