Inline comments:
In `@adapters/claude/README.md`:
- Around line 124-125: Update the Relay dependency wording in
adapters/claude/README.md lines 124-125 and adapters/codex/README.md lines
148-149 to state that the adapter provides no relay extra, and identify the root
nemo-fabric[relay] extra as installing only the Relay Python library, not the
CLI.
In `@crates/fabric-core/src/config.rs`:
- Around line 1511-1598: Update the generic observability component validation
in the relay.components loop to inspect each OpenTelemetry endpoint and reject
endpoint values that are blank after trimming. Return invalid_config using the
path relay.components.{index}.config.opentelemetry.endpoints.{i}.endpoint,
matching the typed observability validation behavior.
- Around line 1167-1179: Add a unit test for RelayOpenTelemetryConfig
deserialization that uses a complete v3 opentelemetry section containing enabled
and endpoints, then assert the resulting extensions map is empty. Keep enabled
and endpoints as typed fields on RelayOpenTelemetryConfig so
relay_legacy_flat_otel_field does not classify them as legacy fields.
In `@docs/getting-started/install.mdx`:
- Around line 184-202: Replace the bold fragment headings introducing the shell,
PowerShell, and Cargo installation blocks with complete lead-in sentences, while
preserving the existing commands and version details. Ensure each sentence
explicitly describes the installation method and ends before its corresponding
code block.
- Line 169: Update the heading near “Migrate Relay observability configs from
0.6” to title case, capitalizing the principal words while preserving the
existing wording and version.
In `@python/src/nemo_fabric/models.py`:
- Around line 1128-1146: The SDK contract test for enable_relay should verify
that the Relay configuration round trip preserves a Path-valued output_dir and
an unknown field stored in model_extra. Add assertions after invoking
enable_relay, using the existing Relay configuration test symbols, and ensure
both values remain unchanged after RelayConfig.model_validate and model_dump.
- Around line 771-818: Update _validate_observability_component_versions so raw
mapping components with non-mapping config values are normalized to an empty
mapping before evaluating version, openinference, or opentelemetry. Preserve
validation of valid mapping configs and ensure invalid config shapes produce a
Pydantic ValidationError rather than a TypeError.
- Around line 681-707: Raise the Pydantic dependency floor in
python/pyproject.toml to >=2.12,<3 so the exclude_if fields in
RelayOpenTelemetryEndpointConfig serialize correctly, then regenerate
python/uv.lock to reflect the updated requirement and resolved versions.
In `@tests/adapters/test_adapaters_common_utils.py`:
- Around line 406-415: Update the two split message values in the parametrize
list by wrapping each intentional adjacent string concatenation in parentheses,
preserving their exact resulting text and resolving Ruff ISC004.
In `@tests/adapters/test_adapters_common_relay_gateway.py`:
- Around line 52-53: Add a regression case to the version-parsing test matrix
covering a nemo-relay version with build metadata, such as 0.7.2+build.1, and
assert it produces (0, 7, 2). Keep the existing version cases unchanged and
verify the relay_cli_contract acceptance behavior.
In `@tests/adapters/test_deepagents.py`:
- Around line 541-547: Update
test_inherited_relay_config_report_fails_before_agent_invocation to obtain
fake_sdks via pytest.mark.usefixtures instead of a function parameter,
preserving its stubbing side effect, and annotate the nested inherited_plugin
helper consistently with plugin_ctx to satisfy ANN202.

CodeRabbit follow-up: I left the two Hermes tests separate. One validates the complete staging/defaulting, ambient-config guard, and artifact path; the other isolates ordered multi-endpoint preservation. Parametrizing only the endpoint list would couple two distinct contracts and make the regression boundary less clear. No code change for that outside-diff suggestion. All inline findings were fixed or answered, and all review threads are resolved. |

In `@crates/fabric-core/src/config.rs`:
- Around line 1596-1611: Update the generic OpenTelemetry validation in
crates/fabric-core/src/config.rs lines 1596-1611 to reject non-object values and
require every endpoint to be an object with a valid type and nonblank endpoint
URL, preferably by deserializing through RelayOpenTelemetryConfig. Apply the
same typed-shape validation to raw component mappings in
python/src/nemo_fabric/models.py lines 823-836, and add matching regression
cases.
Apply the same fix in `@adapters/common/src/nemo_fabric_adapters/common/utils.py`
around lines 453 - 464: The shared adapter validator currently permits missing
endpoint types and non-list endpoint values.
In `@tests/adapters/test_deepagents.py`:
- Around line 541-543: Add `@pytest.mark.usefixtures`("fake_sdks") directly above
test_inherited_relay_config_report_fails_before_agent_invocation so the test
activates the required SDK stubs without consuming the fixture value.

**/*: Before implementing, explicitly state assumptions, surface ambiguity and tradeoffs, present multiple interpretations when relevant, and ask for clarification rather than silently deciding or proceeding when requirements are unclear.
Prefer the minimum code needed to solve the requested problem: avoid speculative features, unnecessary abstractions, unrequested flexibility, and handling of impossible scenarios; simplify overcomplicated solutions.
When editing existing code, make surgical changes only: do not modify unrelated code, comments, formatting, or pre-existing dead code; match the existing style, and remove only unused imports, variables, or functions introduced by your changes.
Define verifiable success criteria for each task, such as writing regression tests for bugs and invalid-input tests for validation, then verify the implementation against those criteria. For multi-step work, state a brief plan with a verification check for each step.

Do not add-> Nonereturn type annotations to test functions.
When mocking a class, useunittest.mock.MagicMockorAsyncMock, using thespecargument when necessary, rather than defining a new class.
Prefix mocked class names withmock, notfake.
Prefer pytest fixtures over helper methods.
If a fixture is needed in multiple test files, define it once inconftest.pyrather than repeating it.
Define fixtures using@pytest.fixture(name="<fixture_name>"[, scope="<scope>"])and a<fixture_name>_fixturefunction; specifyscopeonly when it is notfunction.
Preferpytest.mark.parametrizeover separate tests for different input types.
Use@pytest.mark.usefixtureswhen a fixture is needed but its returned value is unused or it returns no value.
Avoid defensive programming in tests; access expected values directly so missing data raises a clear failure, such as usingresults["data"]instead ofresults.get("data").

Learning: In the NeMo-Fabric adapters, treat path values used in Fabric adapter configuration (including logic like `_resolve_path` in adapter.py) as config-root-relative. Do not apply `Path.expanduser()` (or otherwise apply `~`/home or shell-style expansion), because it will make the resolved paths normalize inconsistently across adapters. Also, do not rely on or add any resolution behavior that uses `harness.settings.cwd` as an override point for these adapter paths—`harness.settings.cwd` is explicitly unsupported in this adapter context.

Timestamp: 2026-06-28T04:03:32.877Z
Learning: In NVIDIA NeMo Fabric Python SDK serialization of `RuntimeCapabilities` (to satisfy the “parity contract” with Rust core and the CLI), do not emit metadata keys when the corresponding metadata is absent. Instead, omit those fields entirely so the produced JSON matches the Rust/CLI output (e.g., avoid `null`, empty objects, or placeholder metadata). During review, verify the serializer/builders follow this omission rule and that Python outputs/parity tests reflect the same shape.

**/*: Before implementing, explicitly state assumptions, surface ambiguity and tradeoffs, present multiple interpretations when relevant, and ask for clarification rather than silently deciding or proceeding when requirements are unclear.
Prefer the minimum code needed to solve the requested problem: avoid speculative features, unnecessary abstractions, unrequested flexibility, and handling of impossible scenarios; simplify overcomplicated solutions.
When editing existing code, make surgical changes only: do not modify unrelated code, comments, formatting, or pre-existing dead code; match the existing style, and remove only unused imports, variables, or functions introduced by your changes.
Define verifiable success criteria for each task, such as writing regression tests for bugs and invalid-input tests for validation, then verify the implementation against those criteria. For multi-step work, state a brief plan with a verification check for each step.
**/*: Always spellNVIDIAin all caps; do not useNvidia,nvidia,nVidia,nVIDIA, orNV.
Usean NVIDIAbefore a noun, because the name begins with an “en” sound.
Do not add a registered trademark symbol afterNVIDIAwhen referring to the company; use trademark symbols with product names only when required by the document type or legal guidance.
Verify official capitalization, spacing, hyphenation, and spelling for NVIDIA and third-party product names; do not rewrite official product names for grammar or title-case rules.
Precede NVIDIA product names withNVIDIAon first mention when natural and accurate, and link the first mention when the destination helps the reader.
On first use, include the company name and full model qualifier when it helps identify the model; preserve official capitalization and punctuation, and use shorter family names only after establishing the full name.

tests/**/*.py: Use pytest to run Python tests.
Do not add@pytest.mark.asyncioto tests; async tests are automatically detected by the async runner.
Do not add-> Nonereturn type annotations to test functions.
When mocking a class, useunittest.mock.MagicMockorAsyncMock, using thespecargument when necessary, rather than defining a new class.
Prefix mocked class names withmock, notfake.
Prefer pytest fixtures over helper methods.
If a fixture is needed in multiple test files, define it once inconftest.pyrather than repeating it.
Define fixtures using@pytest.fixture(name="<fixture_name>"[, scope="<scope>"])and a<fixture_name>_fixturefunction; specifyscopeonly when it is notfunction.
Preferpytest.mark.parametrizeover separate tests for different input types.
Use@pytest.mark.usefixtureswhen a fixture is needed but its returned value is unused or it returns no value.
Avoid defensive programming in tests; access expected values directly so missing data raises a clear failure, such as usingresults["data"]instead ofresults.get("data").
When adapter installation metadata changes, packaging metadata tests must directly assert that the root project depends unconditionally on the exact-versionnemo-fabric-runtimedistribution.
Packaging metadata tests must verify that each root harness extra delegates to the matching version of the leaf adapter'sharnessextra.
Packaging metadata tests must verify that bare leaf dependencies remain adapter-owned and that the rootadapter-testsdependency group installs each leaf through itsharnessextra.
Packaging metadata tests must verify that every leaf providesfull; only adapters importing NeMo Relay Python APIs providerelay, while adapters using an external Relay executable havefullequal toharness.

Timestamp: 2026-06-28T04:03:32.877Z
Learning: In NVIDIA NeMo Fabric Python SDK serialization of `RuntimeCapabilities` (to satisfy the “parity contract” with Rust core and the CLI), do not emit metadata keys when the corresponding metadata is absent. Instead, omit those fields entirely so the produced JSON matches the Rust/CLI output (e.g., avoid `null`, empty objects, or placeholder metadata). During review, verify the serializer/builders follow this omission rule and that Python outputs/parity tests reflect the same shape.

Overview
Upgrade NeMo Fabric to NeMo Relay
>=0.7.2,<0.8and move the public Relay observability configuration to schema v3.This is a hard migration: explicit schema-v2 configurations and removed flat OTLP/OpenInference fields are rejected with actionable errors. Configurations without an explicit observability version follow Relay 0.7's implicit-v3 behavior.
Relay 0.7.2 is the narrowest supported dependency range for this contract. Retaining Relay 0.6 would preserve two configuration models across adapters and retain the Hermes compatibility constraint introduced in #206. The reviewed license delta is limited to
nemo-relaychanging from 0.6.0 to 0.7.2 and the addition ofnemo-relay-cli-bin0.7.2; both packages are Apache-2.0, with no new copyleft or unresolved licenses.Claude and Codex harness installations now depend directly on the supported
nemo-relay-cli-bindistribution, so Platform Evaluator environments receive the version-matched gateway executable without the unused Relay Python package or separate Cargo/shell provisioning. Bare adapter installations remain unchanged.The Python SDK now requires Pydantic 2.12 or newer because the Relay v3 models use
Field(exclude_if=...); older Pydantic releases accept that metadata but do not apply it during serialization.This branch now incorporates merged #197's Claude v1alpha2 adapter contract. The conflict resolution preserves typed
AgentConfiginput while retaining Relay 0.7 validation and schema-v3 configuration.This PR supersedes #215. The branch moved from a fork to
NVIDIA/NeMo-Fabricso the required NVSkills validation can run.Details
