* fix(harness): hydrate run history from RunStore and persist cancellation status
fix:
- Make RunManager.get() async and hydrate from RunStore when in-memory record is missing
- Merge store rows into list_by_thread() with in-memory precedence for active runs
- Persist interrupted status to RunStore in cancel() and create_or_reject(interrupt|rollback)
- Extract _persist_status() to reuse the best-effort store update pattern
- Await run_mgr.get() in all gateway endpoints
- Return 409 with distinct message for store-only runs not active on current worker
Closes#2812, Closes#2813

* fix(harness): consistent sort and guarded hydration in RunManager
fix:
- list_by_thread() now sorts by created_at desc (newest first) even when
no RunStore is configured, matching the store-backed code path
- guard _record_from_store() call sites in get() and list_by_thread()
with best-effort error handling so a single malformed store row cannot
turn read paths into 500s
test:
- update test_list_by_thread assertion to expect newest-first order
- seed MemoryRunStore via public put() API instead of writing to _runs
* fix(harness): guard store-only runs from streaming and fix get() TOCTOU
Add RunRecord.store_only flag set by _record_from_store so callers can
distinguish hydrated history from live in-memory runs. join_run and
stream_existing_run (action=None) now return 409 instead of hanging
forever on an empty MemoryStreamBridge channel.
Re-check _runs under lock after the store await in RunManager.get() so a
concurrent create() that lands between the two checks returns the
authoritative in-memory record rather than a stale store-hydrated copy.

* fix(harness): reorder bridge fetch in join_run and make list_by_thread limit explicit
Move get_stream_bridge() after the store_only guard in join_run so a
missing bridge cannot produce 503 for historical runs before the 409
guard fires.
Add limit parameter to RunManager.list_by_thread (default 100, matching
the store's page size) and pass it explicitly to the store call.
Update docstring to document the limit instead of claiming all runs are
returned.

* fix(harness): cap list_by_thread result to limit after merge
Apply [:limit] to all return paths in list_by_thread so the method
consistently returns at most limit records regardless of how many
in-memory runs exist, making the limit parameter a true upper bound
on the response size rather than just a store-query hint.

* fix(runtime): add update_model_name to RunStore to prevent SQL integrity errors
RunManager.update_model_name() was calling _persist_to_store() which uses
RunStore.put(), but RunRepository.put() is insert-only. This caused integrity
errors when updating model_name for existing runs in SQL-backed stores.
fix:
- Add abstract update_model_name method to RunStore base class
- Implement update_model_name in MemoryRunStore
- Implement update_model_name in RunRepository with proper normalization
- Add _persist_model_name helper in RunManager
- Update RunManager.update_model_name to use the new method
test:
- Add tests for update_model_name functionality
- Add integration tests for RunManager with SQL-backed store

* fix(runtime): handle NULL status/on_disconnect in _record_from_store
`dict.get(key, default)` only uses the default when the key is absent,
so a SQL row with an explicit NULL status would pass `None` to
`RunStatus(None)` and raise, breaking hydration for otherwise valid rows.
Switch to `row.get(...) or fallback` so both missing and NULL values
get a safe default. Add tests for get() and list_by_thread() with a
NULL status row to prevent regression.

* fix(runs): address PR review feedback on store consistency changes
- Fix list_by_thread limit semantics: pass store_limit = max(0, limit - len(memory_records)) to store so newer store records are not crowded out by in-memory records
- Remove dead code: cancelled guard after raise is always True, simplify to if wait and record.task
- Document _record_from_store NULL fallback policy (status→pending, on_disconnect→cancel) in docstring

* refactor: thread app config through lead prompt
* fix: honor explicit app config across runtime paths
* style: format subagent executor tests
* fix: thread resolved app config and guard subagents-only fallback
Address two PR review findings:
1. _create_summarization_middleware passed the original (possibly None)
app_config into create_chat_model, forcing the model factory back to
ambient get_app_config() and risking config drift between the
middleware's resolved view and the model's view. Pass the resolved
AppConfig instance through end-to-end.
2. get_available_subagent_names accepted Any-typed config and forwarded
it to is_host_bash_allowed, which reads ``.sandbox``. A
SubagentsAppConfig (also accepted upstream as a sum-type input) has
no ``.sandbox`` attribute and would be silently treated as "no
sandbox configured", incorrectly disabling the bash subagent. Guard
on hasattr and fall back to ambient lookup otherwise.
Adds regression tests for both paths.
* chore: simplify hasattr guard and tighten regression tests
- Collapse if/else into ternary in get_available_subagent_names; hasattr(None, ...) is False so the explicit None check was redundant.
- Drop comments that narrate the change rather than explain non-obvious WHY (test names already convey intent).
- Replace stringly-typed sentinel "no-arg" in regression test with direct args tuple comparison.

* fix(agents): propagate agent_name into ToolRuntime.context for setup_agent (#2677)
When creating a custom agent via the web UI, SOUL.md was always written
to the global base_dir/SOUL.md instead of agents/<name>/SOUL.md.
Root cause: the bootstrap flow sends agent_name via body.context, but
two layers were broken:
1. services.py only forwarded body.context keys into config["configurable"];
config["context"] was never populated.
2. worker.py constructed the parent Runtime with a hard-coded
{thread_id, run_id} context, ignoring config["context"] entirely.
After the langgraph >= 1.1.9 bump (#98a5b34f), ToolRuntime.context no
longer falls back to configurable, so setup_agent's
runtime.context.get("agent_name") returned None and the tool's silent
agent_name=None -> base_dir fallback kicked in, overwriting the global
SOUL.md.
Fix:
- services.py: extract merge_run_context_overrides() and write the
whitelisted context keys into both configurable (legacy readers) and
context (langgraph 1.1+ ToolRuntime consumers).
- worker.py: extract _build_runtime_context() and merge config["context"]
into the Runtime's context (without letting callers override
thread_id/run_id).
The base_dir fallback in setup_agent_tool.py is left in place because
the IM /bootstrap channel command depends on it. That code path can
be tightened in a follow-up.
Adds regression tests covering both helpers.

* feat: implement full checkpoint rollback on user cancellation
- Capture pre-run checkpoint snapshot including checkpoint state, metadata, and pending_writes
- Add _rollback_to_pre_run_checkpoint() function to restore thread state
- Implement _call_checkpointer_method() helper to support both async and sync checkpointer methods
- Rollback now properly restores checkpoint, metadata, channel_versions, and pending_writes
- Remove obsolete TODO comment (Phase 2) as rollback is now complete
This resolves the TODO(Phase 2) comment and enables full thread state
restoration when a run is cancelled by the user.
* fix: address rollback review feedback
* fix: strengthen checkpoint rollback validation and error handling
- Validate restored_config structure and checkpoint_id before use
- Raise RuntimeError on malformed pending_writes instead of silent skip
- Normalize None checkpoint_ns to empty string instead of "None"
- Move delete_thread to only execute when pre_run_snapshot is None
- Add docstring noting non-atomic rollback as known limitation
This addresses review feedback on PR #1867 regarding data integrity
in the checkpoint rollback implementation.
* test: add comprehensive coverage for checkpoint rollback edge cases
- test_rollback_restores_snapshot_without_deleting_thread
- test_rollback_deletes_thread_when_no_snapshot_exists
- test_rollback_raises_when_restore_config_has_no_checkpoint_id
- test_rollback_normalizes_none_checkpoint_ns_to_root_namespace
- test_rollback_raises_on_malformed_pending_write_not_a_tuple
- test_rollback_raises_on_malformed_pending_write_non_string_channel
- test_rollback_propagates_aput_writes_failure
Covers all scenarios from PR #1867 review feedback.
* test: format rollback worker tests
