Ship recipes/mixins/nvsentinel-observability.yaml, enabling NVSentinel's global.auditLogging and global.tracing chart flags without changing any shipped recipe's default behavior. Both are pure observability additions; neither is enabled by any existing overlay. Since nvsentinel is unconditionally in the base inheritance chain, mixins previously could not set Overrides on it (ADR-005's silent-constraint- override guard). Introduce a narrow, fail-closed alternative instead of relaxing that guard wholesale: components declare a per-path MixinSafeOverridePaths allowlist in registry.yaml, and mixin overrides are validated against it with ancestor/descendant and empty-map collision detection, rejecting anything not explicitly granted or that would silently clobber an existing value. Add CheckNVSentinelTracingEndpointRequired, a bundle-time gate that fails closed when tracing is enabled (via recipe override, --set, --set-json, or --dynamic) without a real endpoint, since the chart itself renders an empty OTLP endpoint without complaint. Add a chainsaw health check for the audit-log init container/volume mount shape, an automated chart-render regression test (excluded from make test via testing.Short(), run weekly via a new non-blocking GitHub Actions workflow), and derive check-health-all's component list from registry.yaml's healthCheck entries so the opt-in check no longer breaks that target on stock clusters. Document the mixin in component-catalog.md and recipe-development.md, including its hostPath disk-cost caveat and the OCP-disabled no-op case. Signed-off-by: Varun Ramesh <varamesh@nvidia.com>

CodeRabbit/re-review round: - validate overrides when a mixin introduces a component fresh (not just when it targets one already in the chain) - clone a mixin's ComponentRef before merging so a second mixin can't mutate the process-wide cached mixin definition - redesign collision detection to check only the mixin's own leaf paths against raw existing layers, fixing two bugs the old flatten- the-whole-tree approach had: it lost an explicit YAML null's provenance, and it hard-failed on any unrelated dotted key (e.g. podAnnotations) anywhere in the component's values - treat an empty-map ancestor as itself configured, closing the remaining bypass - guard Deployment stale-rollout detection against spec.replicas, not status.replicas, which can lag together during a scale-up Simplification pass: - drop a redundant resolveComponentValues call/file-read, deriving the "already disabled" check from the same raw layers - only build those layers when a mixin actually declares Overrides (skip the I/O for structural-only mixins) - trim long comments in metadata_store.go and the Makefile's check-health-all target - dedupe repeated test fixture setup behind two small helpers Signed-off-by: Varun Ramesh <varamesh@nvidia.com>
- clone component refs in RecipeMetadataSpec.Merge's initial componentMap population, not just the new-component insertion path: s.ComponentRefs can itself alias a cached source (e.g. initBaseMergedSpec copies s.Base.Spec.ComponentRefs by struct), so a second layer's overrides were writing straight into that cache - scope the newly-introduced-component override check to registered components only, not "already in this recipe's chain": an unregistered component keeps its pre-existing override freedom (no compatibility break), while a registered component (e.g. nvsentinel) still can't dodge its allowlist by being introduced fresh - document that a registered component's mixinSafeOverridePaths allowlist applies the same way whether a mixin is introducing it fresh or it's already chained Signed-off-by: Varun Ramesh <varamesh@nvidia.com>
A mixin introducing an allowlisted component (e.g. nvsentinel) fresh could supply a non-allowlisted value (global.tracing.endpoint) through ValuesFile instead of inline Overrides, since only Overrides was validated. Reject ValuesFile outright when introducing a component that has a declared mixinSafeOverridePaths allowlist, checked before the len(Overrides)==0 early continue so a ValuesFile-only mixin can't skip validation entirely. Narrowed the new-component gate from "is registered at all" to "has a non-empty allowlist declared": the first version of this gate broke platform-inference/agentgateway-crds and platform-kubeflow/ kubeflow-trainer, which are registered but have never opted into the allowlist mechanism and have always freely supplied ValuesFile/ Overrides when introducing those components fresh. Signed-off-by: Varun Ramesh <varamesh@nvidia.com>
- existingRawOverrideLayers only tolerated fs.ErrNotExist implicitly by treating every base-values read error as "file doesn't exist"; a transient/permission/timeout error silently dropped that collision layer instead of propagating, which could let a mixin overwrite an allowlisted path the (unreadable) base file actually sets. Now only a confirmed not-found is tolerated. - both values-file reads used an unconditional Wrap(ErrCodeInternal), flattening a structured code (e.g. ErrCodeTimeout from a canceled context) from the provider. Switched to PropagateOrWrap so the original code survives at the top level. - corrected docs/contributor/recipe.md: the mixin-introducing-a-new- component carve-out is "no non-empty mixinSafeOverridePaths declared" (most registered components today, e.g. agentgateway-crds, kubeflow-trainer), not "unregistered only". Signed-off-by: Varun Ramesh <varamesh@nvidia.com>
isNotFoundReadError now matches both fs.ErrNotExist (filesystem-backed providers) and the structured ErrCodeNotFound sentinel a custom DataProvider may return instead (already used by pkg/recipe/catalog's stubProvider). Without this, a provider using the structured form for a missing implicit base values.yaml caused mixin composition to fail outright instead of using the overlay ValuesFile alone.

Summary
Add an opt-in
nvsentinel-observabilityrecipe mixin that enables NVSentinel'sglobal.auditLoggingandglobal.tracingchart flags via a narrow, per-path override allowlist, plus a bundle-time gate that fails closed if tracing is enabled without a real OTLP endpoint.Motivation / Context
NVSentinel ships audit logging and distributed tracing behind chart flags that are off by default and have no
requiredguard — enabling tracing without an endpoint renders an emptyOTEL_EXPORTER_OTLP_ENDPOINTsilently. This PR gives operators an opt-in, safe way to turn both on without touching any shipped recipe's default behavior.Fixes: #2617

Rollout notes: Opt-in only — no shipped recipe adopts the mixin, so no existing recipe's resolved values change. Adoption is a recipe-authoring decision (
spec.mixins: [nvsentinel-observability]) on a leaf overlay that is part of the resolved catalog (embedded or--data); it does not work via a direct-r/--configfile, which is documented explicitly.Checklist
