Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This release removes the built-in Switchyard component and requires users to migrate to an external dynamic plugin. The current validation behavior can reject that replacement when it uses the legacy "switchyard" ID, causing migrated configurations to fail startup; this compatibility issue should be resolved or explicitly accepted before merge.

In `@crates/cli/src/server/mod.rs`:
- Around line 908-915: Scope the RemovedSwitchyard validation in the component
validation flow to static components only, so dynamic components with plugin_id
"switchyard" are handled by dynamic activation rather than rejected by the
legacy check. Add coverage for dynamic activation of the switchyard plugin and
keep the existing rejection behavior for legacy static switchyard components.
In `@docs/configure-plugins/adaptive/response-cache.mdx`:
- Around line 402-403: Update the response-cache priority guidance to state that
any routing plugin setting x-nemo-relay-internal-dispatch-backend must have a
lower priority than response_cache.priority, ensuring the backend is included
when cache keys are derived.

**/*.{md,mdx,rst}: Use title case consistently for technical documentation headings and table headers; avoid quotation marks, ampersands, and exclamation marks in headings, while preserving official product, event, research, and whitepaper title case.
Format code elements, commands, parameters, package names, expressions, directories, file names, and paths in monospace; represent path placeholders with angle brackets inside monospace.
Format UI buttons, menus, fields, and labels in bold, and separate consecutive UI navigation labels with>.
Use quotation marks for error messages and strings when appropriate, italics for newly introduced terms and publication titles, and plain text for keyboard shortcuts.
Represent GitHub repositories with owner/repository link text, such as[NVIDIA/NeMo](link), rather than generic repository wording.
Introduce every code block with a complete sentence; do not let a code block complete or interrupt the grammar of surrounding prose; use syntax highlighting when supported.
Keep inline method, function, and class references consistent with nearby documentation; omit empty parentheses in prose when no call is shown.
Use descriptive link text matching the destination title when possible; avoid raw URLs, generic anchors, long-sentence links, and unnecessary links that distract from procedures.
Ensure lists have a complete lead-in sentence, more than one item, no more than two levels, parallel construction, one idea or action per item, and appropriate punctuation; use bullets for unordered items and numbers for ordered tasks.
Format definition lists with a bold term followed by a complete, parallel, punctuated definition.
Use tables for reference information, decision support, compatibility matrices, and comparable choices; flag one-row tables, missing captions or lead-ins, sentence-case headers where title case is expected, unexplained empty cells, and code or links that would be clearer as prose.

Preserve the official capitalization and punctuation of model names.
Use shorter family names only after the full name is established.
Spell out a term on first use and put the acronym in parentheses unless the acronym is widely understood by the intended audience.
Use the acronym on later mentions after it has been defined.
For long documents, reintroduce the full term if readers might lose context.

In headings, common acronyms can remain abbreviated. Spell out the term in the first or second sentence of the body.

Timestamp: 2026-07-28T20:07:29.880Z
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.

908-915: Keep the legacy check out of dynamic component validation.This is the same unresolved finding from the previous review.
PluginActivation::initializeappends dynamic plugin IDs toPluginConfig.componentsbefore calling this validator. A dynamic plugin withplugin_id == "switchyard"is therefore reported asRemovedSwitchyardbefore native or worker activation. Apply the removal check only to legacy static components, or verify that the replacement plugin cannot use this ID.
843-876: LGTM!Also applies to: 898-899

#### Overview Validate user-authored static components before the CLI synthesizes component specs for dynamic plugins. This prevents a dynamic plugin whose `plugin_id` is `switchyard` from being rejected as the removed legacy static Switchyard component. This follow-up was rebased onto `main` after #811 merged and now contains only the isolated ordering fix. - [x] I confirm this contribution is my own work, or I have the right to submit it under this project's license. - [x] I searched existing issues and open pull requests, and this does not duplicate existing work. #### Details - Run built-in component registration and legacy static-component validation against the parsed base `PluginConfig`. - Append synthesized dynamic component specs only after that static validation succeeds. - Preserve rejection of enabled and disabled legacy `[[components]] kind = "switchyard"` entries, with direct regression coverage for both states. - Add regression coverage showing dynamic `plugin_id = "switchyard"` reaches dynamic activation and receives its dynamic manifest diagnostic instead of the legacy migration error. Validation completed successfully: - `cargo test -p nemo-relay-cli --lib server::tests::register_and_validate_plugin_components_rejects_legacy_switchyard_components -- --exact` (1 passed) - `cargo test -p nemo-relay-cli --lib server::tests::plugin_activation_covers_empty_invalid_and_missing_manifest_paths -- --exact` (1 passed after rebase) - `cargo fmt --all -- --check` - `cargo clippy --workspace --all-targets -- -D warnings` - `just build-test-plugin-fixtures` - `just test-python-plugin` (140 passed) - `just test-rust` - `uv run pre-commit run --all-files` Breaking changes: none. Dynamic plugins continue to validate and activate through their registered plugin kinds; the change only prevents them from being mistaken for user-authored legacy static components. #### Where should the reviewer start? Start with the validation ordering in `crates/cli/src/server/mod.rs`, followed by the static and dynamic Switchyard regressions in `crates/cli/tests/coverage/shared/server_tests.rs`. #### Related Issues: (use one of the action keywords Closes / Fixes / Resolves / Relates to) - Relates to #811 - Relates to NVIDIA-NeMo/Switchyard#270 ## Summary by CodeRabbit * **Bug Fixes** * Improved validation for plugin configurations before dynamic components are activated. * Legacy Switchyard components are now consistently rejected with a clear removal error. * Updated error reporting to identify unsupported native dynamic plugins without outdated removal messaging. * **Tests** * Expanded coverage for enabled and disabled legacy Switchyard components. * Added coverage for dynamic Rust plugins without manifests.

BREAKING CHANGE: NeMo Relay 0.8 no longer ships the built-in
nemo-relay-switchyardcrate, CLIswitchyardfeature, or service-backedswitchyardcomponent. Existing configurations must remove the legacy component and migrate to the Switchyard-owned dynamic plugin documented and released with Switchyard 0.3. See the Switchyard migration guide.Overview
This PR removes NeMo Relay's built-in, service-backed Switchyard integration before the 0.8.0 release candidate. It supersedes PR #595 with a clean change based on current
main.Details

switchyardcomponent or provides thenemo-relay-switchyardcrate and CLI feature.Validation completed successfully:
