Sydney Runkle bfec964248 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 57be304f55 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.

Sydney Runkle 43ecd9dc2d 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.

- 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:

Sydney RunkleandClaude Sonnet 4.6 350182ed18 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 4c2ce5c8a9 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 1bb1811fbd 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

Sydney RunkleandClaude Sonnet 4.5 9e40dee07f 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.

Sydney RunkleandGitHub 51cbdbd5cd fix: time travel when going back to interrupt node (#7498) 
# Fix: Create fork checkpoint on subgraph time travel

## Problem

When time-traveling to a subgraph checkpoint that has an interrupt, and
then resuming, the resume would load the **wrong state** — it would pick
up the original execution's latest checkpoint instead of the
time-traveled one.

This happened because replaying from a subgraph checkpoint never created
a new parent checkpoint. If the replay hit an interrupt before
`after_tick()` ran, no checkpoint was written at all, so the parent's
"latest" checkpoint was still the old one from the original execution.

## Fix

When the loop detects a time-travel replay (not an `update_state` fork),
it now **eagerly writes a fork checkpoint** at the start of the tick.
This ensures:

1. The parent thread's latest checkpoint points to the replayed state
2. Subsequent `Command(resume=...)` calls find the correct checkpoint
3. Stale `INTERRUPT` pending writes from the old checkpoint are cleared
(they reference old task IDs)

Additionally, the subgraph replay logic now uses the **parent checkpoint
ID** (from `prev_checkpoint_config`) when resolving subgraph checkpoints
during time-travel, matching the existing behavior for `update_state`
forks.

## Checkpoint flow diagrams

### Before fix: time travel leaves no fork

```
Original execution:

  C0 (start) --> C1 (step_a) --> C2 (ask_1 interrupt) --> C3 (resume) --> C4 (ask_2 interrupt) --> C5 (done)

Time travel to C2 (subgraph config):

  Replay runs... hits interrupt... no new checkpoint written.
  Parent "latest" is still C5.

  Command(resume="new_answer"):
    Loads C5 (wrong!) instead of the replayed C2 state.
```

### After fix: time travel creates a fork

```
Original execution:

  C0 --> C1 --> C2 --> C3 --> C4 --> C5 (done)

Time travel to C2 (subgraph config):

  C0 --> C1 --> C2 --> C3 --> C4 --> C5
                  \
                   F1 (fork, source="fork")  <-- new latest

  Command(resume="new_answer"):
    Loads F1 (correct!) --> resumes from the right state.

  After full resume:

  C0 --> C1 --> C2 --> C3 --> C4 --> C5
                  \
                   F1 --> F2 (ask_1 result) --> F3 (ask_2 interrupt) --> F4 (done)
```

### Manual fork via `update_state` (unchanged)

```
  C0 --> C1 --> C2 --> C3
                  \
                   U1 (source="update")  <-- created by update_state()

  This path already worked. The fix skips update/fork sources
  so existing behavior is preserved.
```

## Changes

- **`libs/langgraph/langgraph/pregel/_loop.py`**:
- Extract `is_time_traveling` flag from the existing replay detection
logic for reuse
- Write a fork checkpoint (`source="fork"`) eagerly at the start of a
time-travel tick, before execution begins
- Clear stale `INTERRUPT` pending writes when creating the fork (they
reference old task IDs that won't match the new checkpoint)
- Unify subgraph replay ID resolution: check `source in ("update",
"fork")` instead of a separate `is_time_traveling` condition, since the
new fork checkpoint now has `source="fork"`
- **`libs/langgraph/tests/test_time_travel.py`** and
**`test_time_travel_async.py`**: Added 4 new test cases (sync + async):
- `test_replay_from_before_interrupt_then_resume` — replays from a
checkpoint before an interrupt, resumes with a new answer, and verifies
the full checkpoint history (source, next, values) at each stage
- `test_subgraph_time_travel_resume_from_first_interrupt` — time-travels
to a subgraph's first interrupt, resumes both interrupts with new
answers, and verifies the fork creates a new branch while preserving the
original
- `test_subgraph_time_travel_resume_from_second_interrupt` —
time-travels to a subgraph's second interrupt, resumes with a new
answer, and verifies the first interrupt's original answer is preserved
- `test_subgraph_time_travel_checkpoint_pattern` — verifies the fork
checkpoint branches from the correct replay point and that the full
checkpoint tree is correct after resume
- **`libs/langgraph/tests/test_pregel.py`** /
**`test_pregel_async.py`**: Updated existing
`test_weather_subgraph_state` to account for the new fork checkpoint
appearing in history (history length increases by 1)
