WalkthroughThe deepagents adapter now propagates valid UUID request IDs through Relay scope stacks. Non-UUID IDs retain metadata-only behavior. Adapter, integration, and end-to-end tests verify correlation and scope restoration. ChangesRelay request correlation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR makes caller-provided UUID request IDs control telemetry and session attribution, which could cause incorrect cross-request or cross-tenant attribution if those IDs are not authenticated or tenant-bound; cancellation cleanup may also leave stale attribution state in a narrow failure path. The change is otherwise mergeable with explicit owner awareness and follow-up on these bounded risks. Sequence Diagram(s)sequenceDiagram

Overview
Use a UUID Fabric
request_idas the propagated Relay root for Deep Agents telemetry. When the request ID is not a UUID, preserve the existing correlation behavior by recording it asnemo_fabric_request_idmetadata.This is intentionally a Fabric-only adapter change: it does not add a session field or change the RunRequest, runtime-context, or adapter schemas.
Details
runtime_context.request_idwith Python's UUID parser.With
session_id_source = "propagation_root"from NVIDIA/NeMo-Relay#959, the same UUID is emitted as the ATIFsession_idwhile Relay retains a distinct Agent/trajectory UUID.Validation
uv run --no-sync pytest tests/adapters/test_deepagents.py tests/integrations/test_relay_scope_leak.py— 80 passedjust --set no_uv true test-python— 1,247 passed, 17 skippedgit diff --checkrequest_id == session_idand a distincttrajectory_idNot run: Rust and TypeScript suites because this change does not touch Rust, TypeScript, schemas, or native bindings.
Where should the reviewer start?
Start with
_relay_request_contextand its use around the Agent scope inadapters/deepagents/src/nemo_fabric_adapters/deepagents/adapter.py. The main design decision is to treat a UUID request ID as an explicit propagation signal while retaining metadata fallback for existing non-UUID IDs.Related Issues: (use one of the action keywords Closes / Fixes / Resolves / Relates to)
Relates to [Enhancement]: Allow ATIF session IDs to use the propagated root NeMo-Relay#958
