WalkthroughThe PR adds bounded runtime diagnostic snapshots, typed mark schemas and severities, metric emission APIs, a diagnostics RPC, native ABI compatibility from versions 2 through 4, and matching Rust and Python SDK support. ChangesTelemetry and runtime diagnostics extensions
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The PR adds native ABI v4 callbacks and worker runtime diagnostics, but the current implementation can reject existing ABI v4 plugin hosts when the newly appended callbacks are absent, creating a compatibility risk for dynamic plugins. Merge should wait for that negotiation behavior to be corrected or explicitly accepted by the owner. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@crates/core/src/plugin/dynamic/native.rs`:
- Around line 1297-1309: Update native_get_runtime_diagnostics to serialize
diagnostics with a fallible serde_json operation before constructing the
response object, avoiding json! for the diagnostics value. Preserve the existing
write_native_json success path and set_native_last_error plus
NemoRelayStatus::Internal failure path when serialization fails.
In `@crates/core/tests/fixtures/native_plugin/src/lib.rs`:
- Around line 389-420: Update nemo_relay_fixture_native_plugin_v3 to delegate to
fixture_compat_entry instead of duplicating host validation and plugin
descriptor construction, so the ABI version and minimum struct_size checks are
consistently exercised.
In `@crates/core/tests/integration/native_plugin_tests.rs`:
- Around line 296-305: Extend the assertions for the metric returned by
find_event in the native plugin integration test to validate the serialized
measurements[0] fields name, kind, and value_type, using the exact contract
spellings emitted by the fixture and MetricKind/MetricValueType. Keep the
existing schema and value assertions unchanged.
In `@crates/plugin/src/lib.rs`:
- Around line 1209-1265: Add a compile-time assertion linking
NemoRelayNativeHostApiV4TypedAsync to the frozen pre-emit_mark_v2 prefix of
NemoRelayNativeHostApiV4, verifying that their layouts and sizes remain
identical. Place it near the existing ABI size constants so future field
reordering or insertion before emit_mark_v2 fails compilation.
In `@crates/plugin/tests/typed_callbacks.rs`:
- Around line 2605-2632: Add an assertion in
plugin_runtime_uses_v4_mark_options_extension after emit_mark_with_options to
verify STRING_LIVE_COUNT has returned to its pre-call value, covering cleanup of
the data schema and severity host-string allocations as well as the existing
strings.
In `@crates/worker-proto/proto/nemo/relay/worker/v1/plugin_worker.proto`:
- Line 21: Document the public worker protocol changes around
GetRuntimeDiagnostics and the typed mark fields, adding usage examples that
demonstrate the new RPC and fields. Keep the documentation aligned with the
exposed request/response API and update the relevant protocol examples in the
same change.
In `@crates/worker-proto/tests/proto_tests.rs`:
- Around line 129-138: Pin protobuf field numbers with regression coverage: in
crates/worker-proto/tests/proto_tests.rs lines 129-138, assert stable encoded
bytes for GetRuntimeDiagnosticsResponse.entries; in lines 215-228, assert stable
field tags for EmitMarkRequest.data_schema and EmitMarkRequest.severity; and in
justfile lines 1070-1076, add generated-descriptor checks for all three fields.
In `@python/plugin/src/nemo_relay_plugin/__init__.py`:
- Around line 20-24: Add public SDK documentation and usage examples for
emit_mark options, emit_metric, runtime_diagnostics, and the unsupported-host
error path, covering the newly exported typed mark, metric, and diagnostics
APIs. Keep the documentation aligned with the implemented behavior and include
examples in the same branch.
In `@python/tests/plugin/test_worker_sdk.py`:
- Around line 2313-2330: Replace the hand-written OldHostStub in the
runtime_diagnostics test with a spec-backed MagicMock using RecordingHostStub as
the spec, and configure GetRuntimeDiagnostics as an AsyncMock that raises
UnimplementedRuntimeDiagnosticsError. Preserve the existing grpc.aio.AioRpcError
patch and WorkerSdkError assertion.

Learning: In NeMo Relay first-party plugin registration helpers, treat the documented duplicate-registration `PluginError::RegistrationFailed` result from `register_plugin` as success when registration is intended to be idempotent. Do not locally reclassify this as `PluginError::Conflict`; changing the classification requires a core-wide review of the public API and FFI behavior.

Learning: In NeMo Relay (RELAY-509), sanitizer callback failures must be treated as intentional fail-open behavior. When an event/tool (request/response) or LLM (request/response) sanitizer callback fails, the sanitizer chain should retain and publish the last valid event/payload snapshot (rather than dropping/invalidating the data) and log the failure including callback context (e.g., which sanitizer/callback failed and relevant identifiers). Apply this consistently across all sanitizer chains mentioned in the RELAY-509 documentation/migration guide.

📚 Learning: 2026-08-03T19:55:03.931Z
Learnt from: afourniernv
Repo: NVIDIA/NeMo-Relay PR: 558
File: crates/pii-redaction/src/rampart/mod.rs:265-274
Timestamp: 2026-08-03T19:55:03.931Z
Learning: In NeMo Relay first-party plugin registration helpers, treat the documented duplicate-registration `PluginError::RegistrationFailed` result from `register_plugin` as success when registration is intended to be idempotent. Do not locally reclassify this as `PluginError::Conflict`; changing the classification requires a core-wide review of the public API and FFI behavior.

Learning: In NeMo Relay (RELAY-509), sanitizer callback failures must be treated as intentional fail-open behavior. When an event/tool (request/response) or LLM (request/response) sanitizer callback fails, the sanitizer chain should retain and publish the last valid event/payload snapshot (rather than dropping/invalidating the data) and log the failure including callback context (e.g., which sanitizer/callback failed and relevant identifiers). Apply this consistently across all sanitizer chains mentioned in the RELAY-509 documentation/migration guide.

Overview

This PR is independently rebased on
mainafter #780. It contains only the dynamic-plugin and worker-SDK implementation layer; the consolidated user documentation remains in separate draft PR #795. Review and merge this implementation independently from the Python, Node.js, and C FFI/Go follow-up PRs.Details

No handshake capability is required: an older host returns gRPCUNIMPLEMENTED, which the Rust and Python worker SDKs translate to a clear unsupported-runtime-diagnostics error.Validation:
