The component catalog documented the gpuStack profile values thoroughly but never stated what AICR actually ships: NVSentinel runs in the upstream chart's monitoring-only configuration, with the datastore and remediation components off. The catalog and API reference instead described the component as performing 'automated remediation' that 'can cordon or drain affected nodes', which no shipped bundle does. Add a Deployment Posture section listing what is on and off by default (verified against chart v1.20.0), what the practical effect is, and how to enable remediation until NVIDIA#1014 lands a supported opt-in path - including the privileged reboot Job, the datastore dependency, and the arm64 caveat. Record that NVSentinel is required rather than optional, and draw the line between platform-correctness values AICR does set and enablement toggles it does not.

NVSentinel is included by default rather than universally required: EKS and OKE configurations can disable it, the OCP overlay does (recipes/overlays/ocp.yaml sets overrides.enabled false), and only the AKS and GKE-COS gpuStack profiles lock its presence. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
The values file does override one upstream enablement default (networkPolicy.enabled) and does select the reboot mechanism (janitor-provider.csp.provider), so 'sets no enablement toggles' and 'not policy' were both too broad. Scope both claims to component enablement, and name the two overrides explicitly. Also restate the presence paragraph so base membership and bundle-time excludability are distinguished rather than reading as a contradiction. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
The recipes assign labeler.assumeDriverInstalled and metadata-collector.runtimeClassName only where the chart default does not match the cluster; EKS and most platforms correctly leave them unset, as the tables in the same section show. Say that, rather than implying any chart default breaks the component. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>
The paragraph's job is the boundary between platform-correctness values and enablement policy. Restating when each value is needed duplicated the tables below it and got the detail wrong twice: AKS operator-managed assigns the chart-default false deliberately to keep the path profile-owned, and a missing runtimeClassName is rejected at admission rather than failing silently. Defer to the section that already covers both. Signed-off-by: Yuan Chen <yuanchen97@gmail.com>

| There is no supported opt-in mechanism in AICR yet — [#1014](https://github.com/NVIDIA/aicr/issues/1014) tracks adding one. Until it lands, enabling remediation means setting the chart's own values, and the configuration is yours to validate: | ||

MAJOR — Remove the incomplete remediation command
This command enables the six remediation components but leaves fault-remediation.maintenance at chart defaults. In pinned NVSentinel v1.20.0, COMPONENT_RESET therefore renders as RebootNode, while upstream's self-contained remediation configuration maps the same recoverable fault to GPUReset. A user who copies the example can cordon, drain, and reboot an entire node for a fault upstream handles in place.
Minimum correction: remove the raw --set example and point to #1014 and the pinned upstream guidance until AICR owns a complete, qualified values file. If AICR keeps a recipe, make it self-contained and add a render regression covering the action mapping.

Confirmed and applied in ae98b6e — thanks, this was a genuine hazard and I verified it against the pinned chart rather than taking it on trust.
charts/fault-remediation/values.yaml in v1.20.0 maps COMPONENT_RESET to kind: RebootNode with equivalenceGroup: restart, while values-remediation.yaml maps the same action to kind: GPUReset with impactedEntityScope: GPU_UUID and supersedingEquivalenceGroups: ["restart"]. So the example enabled the pipeline while leaving the action mapping at the destructive default — a partial enablement is not a milder remediation than none, it is a worse one.
Took the minimum correction:
- Removed the
--setblock entirely. - The section now states plainly that AICR does not support enabling remediation today and that this page carries no recipe for it, with [Feature]: Add remediation-enabled overlay profile for clusters with cloud-provider credentials #1014 as the tracking issue.
- Explained why the six flags are not sufficient, naming the
COMPONENT_RESETmapping difference, so a reader who was going to compose the flags themselves understands the trap rather than just being told no. - Pointed at the chart's self-contained
values-remediation.yaml(pinned viarecipes/registry.yaml) as the starting point if someone needs this before [Feature]: Add remediation-enabled overlay profile for clusters with cloud-provider credentials #1014, with the caveat to qualify it on a cluster they can afford to have rebooted. - Kept the privileged-reboot, datastore and arm64 caveats.
I did not add a render regression on the action mapping — with no AICR-owned remediation values file to render, there is nothing yet to assert against. That belongs with #1014 when AICR takes ownership of the configuration, and I have noted it there.
The six enablement flags start the pipeline but leave fault-remediation.maintenance.actions at subchart defaults, where COMPONENT_RESET maps to kind RebootNode. Upstream's own remediation values map the same action to GPUReset scoped to the affected GPU UUID, so copying the example would cordon, drain and reboot a whole node for a fault upstream handles in place - a partial enablement is more destructive than none, not milder. State plainly that AICR does not support enabling remediation yet, point at NVIDIA#1014 and at the chart's self-contained values-remediation.yaml, and keep the privileged-reboot, datastore and arm64 caveats.

Summary
Document what AICR actually ships for NVSentinel — the upstream chart's monitoring-only configuration, with the datastore and remediation components off — and correct two catalog entries that described the component as performing remediation no shipped bundle performs.
Motivation / Context
The component catalog covers the
gpuStackprofile values (labeler.assumeDriverInstalled,metadata-collector.runtimeClassName) in depth, but never states the deployment posture those values sit inside. Greppingdocs/formongodbStore,janitor,janitorProvider,faultQuarantine,nodeDrainer,faultRemediationreturns zero hits — so the fact that remediation is off by default, and what it would take to turn on, is written down nowhere.The gap has practical cost. The same question has been re-derived from scratch in three separate discussions over four months, and consumers integrating AICR have had to reconstruct the posture themselves. Two doc entries actively pointed the wrong way, describing NVSentinel as performing "automated remediation" that "can cordon or drain affected nodes" — accurate for the chart's capability, wrong for every configuration AICR generates.

New
## NVSentinel Deployment Posturesection indocs/user/component-catalog.md, placed before the existing provider-installed-driver section:recipes/components/nvsentinel/values.yamlsets: deployment-shaping values only, enabling and disabling no NVSentinel component. The two values that do select behavior are named explicitly —networkPolicy.enabled: false(the one upstream default overridden here) andjanitor-provider.csp.provider: generic(the reboot mechanism used if remediation is enabled, which it does not enable). Every component on/off default is the chart's.v1.20.0— the version pinned inrecipes/registry.yaml— viahelm show values, not from memory.### Enabling Remediationsubsection stating plainly that no supported opt-in exists yet ([Feature]: Add remediation-enabled overlay profile for clusters with cloud-provider credentials #1014 tracks it), with the--setkeys and three caveats: thegenericprovider's privilegedchroot /host /sbin/rebootJob, the datastore dependency, and the arm64 image gap with the Percona workaround ([Feature]: ARM64 (linux/arm64) support for the internal MongoDB datastore path NVSentinel#1328).base.yamlincludes it unconditionally and ADR-018 classifies itcore, but the OCP overlay overridesenabled: false, and on platforms with nogpuStackprofile (EKS, OKE) a bundle-time exclusion is accepted. Only the AKS and GKE-COS profiles lock presence.Corrected entries. The catalog component table and the API reference component list both read "GPU health monitoring and automated remediation"; the catalog row added "Detects GPU errors and can cordon or drain affected nodes." Both now describe the shipped configuration and link to the new section.
Deliberately not in scope, each worth a follow-up:
recipes/components/nvsentinel/values.yaml:50cites "ADR-028: generic bare-metal reboot provider", which does not exist indocs/design/(the tree stops at 023). It most likely refers to an upstream NVSentinel ADR, but the reference is ambiguous as written.janitor-provider.csp.provider: genericfor a subsystem that is disabled — harmless, but a reader reasonably takes it as evidence remediation is active.coreclassification ("its node remediation is part of the GPU runtime") rests on a capability disabled in every shipped recipe. The classification still holds on the GPU-bound monitoring DaemonSets, but the stated reasoning does not match the configuration.docs/integrator/talos-integration.md:60calls NVSentinel a "health and observability daemon" — accurate, and now consistent with the catalog, so no edit was needed.Testing
Also verified: the new
#nvsentinel-deployment-postureanchor is referenced only from within the same file, and no existing inbound anchor link was renamed or removed (component-catalog.md#nvsentinel-on-provider-installed-driver-platformsand the three other referenced anchors are unchanged).Full

Rollout notes: Documentation only; no behavior change. The corrected component descriptions may read as a capability reduction, but they describe the configuration AICR has always generated.
