Sydney Runkle eb0687a108 refactor(postgres): replace recursive CTE with two-query ancestor walk for DeltaChannel 
Instead of a recursive SQL CTE, collect the ancestor checkpoint ID chain in
Python by fetching all (checkpoint_id, parent_checkpoint_id) for the thread
in one query, then fetch writes with a plain WHERE checkpoint_id = ANY(...).

Simpler, avoids recursive query planner overhead, and uses well-indexed lookups.

Sydney Runkle 4a6ddbb0e3 feat(delta-channel): store sentinel in blobs, reconstruct from checkpoint_writes 
DeltaChannel.checkpoint() now returns a zero-byte DeltaChannelSentinel
instead of duplicating delta data in checkpoint_blobs. Reconstruction
walks the parent checkpoint chain via checkpoint_writes (which already
holds per-step writes) and replays them through the operator.

In-memory benchmark (100 turns, ~20K tokens):
  storage: 10.2 MB → 40.5 KB (251x reduction)
  read:    0.6ms → 7.9ms (reconstruction cost, amortized by storage savings)

InMemorySaver and PostgresSaver override get_channel_writes() with
efficient implementations (Python dict walk and recursive CTE respectively).
The base class fallback uses self.list() with a thread-local recursion guard.

Sydney Runkle 5d72a3f390 refactor(delta-channel): infer typ from Annotated outer type instead of constructor arg 
Remove the positional `typ` parameter from `DeltaChannel.__init__`. The type is
now injected automatically from the `Annotated` outer type in `_is_field_channel`
(matching how `BinaryOperatorAggregate` receives its type). `copy()` and
`from_checkpoint()` propagate `self.typ` explicitly. Test helpers updated to
use `_get_channel` with the proper `Annotated` path.

Sydney Runkle 49ad3044a7 chore(delta-channel): remove supports_delta_channels flag 
Rely on the runtime raise in DeltaChannel.from_checkpoint() instead of
a compile-time boolean flag. Savers that assemble DeltaChainValue inside
_load_blobs work transparently; savers that don't will pass through a raw
DeltaValue and hit a clear ValueError on first reload.

Removes: BaseCheckpointSaver.supports_delta_channels, the attribute on
InMemorySaver / PostgresSaver / AsyncPostgresSaver, the compile-time
UserWarning in StateGraph.compile(), and the associated test.

ccurmeandSydney Runkle 51cd095427 fix(prebuilt): handle injected NotRequired keys (#7392) 
Resolves https://github.com/langchain-ai/langchain/issues/35585

This would previously raise KeyError:
```python

from langgraph.prebuilt import InjectedState
from langchain.agents import AgentState


class CustomAgentState(AgentState):

    """Get weather for a given city."""
    if city is None:
        city = "Boston"
    return f"It's always sunny in {city}!"


agent = create_agent(
    model="claude-sonnet-4-6",
    tools=[get_weather],
    system_prompt="You are a helpful assistant",

Sydney Runkle c185102642 fix(delta-channel): support non-list reducers (dict) and fix MISSING handling 
Use typ() instead of [] throughout DeltaChannel so reducers over dict
(and other non-list types) work correctly. fromCheckpoint(MISSING) now
leaves value as typ() from __init__ instead of overwriting with MISSING.
copy() uses value.copy() to handle dicts. update() initialises base from
typ() when value is MISSING. Add four tests covering the deepagents-style
dict-merge / file-deletion reducer pattern.

Sydney RunkleandClaude Sonnet 4.6 b993e2d37d chore(delta): rename _steps_since_rehydrate → _steps_since_snapshot; add audit tests 
- Rename `_steps_since_rehydrate` → `_steps_since_snapshot` in DeltaChannel
  for clarity (counts steps since the last snapshot, not since rehydration)
- Pre-seed cycle-detection `visited` set with current checkpoint ID in both
  sync and async `_assemble_delta_channels` to prevent self-referential chains
- Add 4 new unit tests:
  - `test_delta_channel_snapshot_every_emits_plain_list`: verifies counter
    semantics and snapshot/delta transitions
  - `test_delta_channel_snapshot_every_end_to_end`: graph-level smoke test
  - `test_delta_channel_assembly_fast_path_returns_delta_value`: exercises
    chain traversal via get_channel_blob returning DeltaValue then plain list
  - `test_delta_channel_assembly_broken_chain_logs_warning`: partial chain

Sydney RunkleandClaude Sonnet 4.6 2d39d536fe fix: register DeltaValue in SAFE_MSGPACK_TYPES; rename _is_diff_delta; cross-saver benchmark 
- Add DeltaValue to SAFE_MSGPACK_TYPES so SQLite and other msgpack-based
  savers don't emit "Deserializing unregistered type" warnings.
- Rename _is_diff_delta → _is_delta_value (leftover from DiffChannel rename).
- Parametrize benchmark by checkpointer: runs InMemory (fast-path) and
  SQLite (get_tuple fallback) in the same table, sharing the _run_turns helper.

Sydney RunkleandClaude Sonnet 4.6 c07f081e4c fix(delta-channel): fix chain assembly and get_state paths 
- Fix InMemorySaver.get_channel_blob: use correct storage[thread_id][ns]
  nesting and deserialize the checkpoint before extracting channel_versions.
- Pass checkpoint_id to after_checkpoint() in channels_from_checkpoint so
  DeltaChannel seeds _last_checkpoint_id correctly on load; without this
  every turn broke the chain at its boundary.
- Wire _assemble_delta_channels into _prepare_state_snapshot and
  _aprepare_state_snapshot (get_state / get_state_history paths) and into
  perform_superstep / aperform_superstep (update_state paths) — previously
  only the loop __enter__ path did assembly.
- Fix test_get_channel_blob to use the correct storage structure.

Sydney RunkleandClaude Sonnet 4.6 d5507cb53c fix(checkpoint/postgres): pass cursor to avoid deadlock in diff chain traversal 
Fixes a critical deadlock that occurs when _load_diff_chains calls self._cursor()
from within _load_blobs while the outer _load_checkpoint_tuple already holds
self._cursor(). On bare (non-pool) connections, the threading.Lock is not
reentrant, causing a deadlock.

Solution: Pass the cursor as a parameter to _load_diff_chains and _load_blobs
instead of acquiring a new cursor within those methods. Updated _load_checkpoint_tuple
to acquire a cursor once at the top level and pass it through the call chain.

Changes:
- Updated _load_blobs signature to accept optional cur parameter
- Updated _load_diff_chains signature (base and implementations) to accept optional cur parameter
- Modified _load_checkpoint_tuple in PostgresSaver to acquire cursor and pass it
- Modified _load_checkpoint_tuple_async to acquire cursor only when diff_payloads exist
- Removed nested self._cursor() calls in _load_diff_chains and _load_diff_chains_async

`test_diff_channel_chain_reconstruction` that skips gracefully when
`langgraph` core is not installed.

Sydney RunkleandClaude Sonnet 4.5 99bc8bb9af feat(checkpoint/serde): serialize DiffDelta as 'diff' type tag 
Add serde support for DiffDelta by implementing dump/load for the "diff" type tag.
This allows the checkpoint system to efficiently store delta objects by serializing
them as msgpack-encoded dicts with {"d": delta, "p": prev_version} structure.

The implementation uses runtime type checking to avoid circular imports and
leverages the existing msgpack ext hooks for proper deserialization of complex
types like LangChain messages.

 		0a26b471d3 fix(langgraph): don't propagate ReplayState to subgraphs on plain resume (#7561) 
**Description:**
When clients resume an interrupted subgraph with `Command(resume=...)`
plus an explicit `checkpoint_id` in the config (the pattern LangGraph
Studio and the API server emit on every resume), the subgraph restarts
from its first node instead of continuing at the interrupted node.

Fix: gate `ReplayState` propagation on `is_time_traveling` rather than
`is_replaying`, so a resume that happens to carry a head checkpoint_id
behaves the same as one with just a thread_id.

**Verification:** added regression test
`test_subgraph_interrupt_resume_with_explicit_head_checkpoint_id` (fails
on main, passes with fix, across memory/sqlite/sqlite_aes).
Full `test_time_travel.py`, `test_time_travel_async.py`,
`test_interruption.py`, and all pregel subgraph/interrupt/resume/replay
tests still pass.
