Request-router PKI modes
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The HA configuration currently omits disruption protection for the API release, so maintenance or node loss may provide less availability protection than the feature promises; invalid PKI secret-name types may also pass validation. These are bounded but concrete merge-readiness risks that should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

- Around line 511-535: Remove the unused nats.jetstream.replicaFactor and
cassandra replicationFactor, replicationStrategy, and consistencyLevel settings
from the public configuration, unless corresponding consumer mappings are added.
Ensure configuration rendering and validation no longer expose orphaned values,
and add render assertions confirming the supported replica settings are
propagated to their actual consumers.
In `@deploy/stacks/self-managed/global.yaml.gotmpl`:
- Around line 43-46: Update the high-availability configuration and rendering
logic so production uses required Tier-1 pod anti-affinity while staging
continues using preferred, preserving multi-node behavior for both profiles. Use
the existing nvcf.ha.isMultiNode and highAvailability.tier1.podAntiAffinity.type
symbols, and add separate render tests covering production and staging outputs.

Map or remove the unused durability settings.
global.yaml.gotmpl does not map replicationFactor, replicationStrategy, consistencyLevel, or jetstream.replicaFactor.
The Cassandra init hook hard-codes NetworkTopologyStrategy and derives replication from cassandra.replicaCount. NATS stream creation uses NatsProperties.replicas, not jetstream.replicaFactor.
Map these settings to their consumers, or remove them from the public configuration. Add render assertions. Update the relevant architecture or sequence diagram if the mapping changes runtime behavior.

Make the production profile enforce its documented placement policy.
production and staging both resolve to multi-node mode. Both then use the same highAvailability.tier1.podAntiAffinity.type, which defaults to preferred in base.yaml. A production deployment can therefore place all Tier-1 replicas on one host.
Select required anti-affinity for the production default and retain preferred for staging. Add separate production and staging render tests.
Also applies to: 61-86
