Rework the logging pipeline around a durable message bus so logs survive a ClickHouse outage, can be replayed after a bad transform, and fan out to multiple independent consumers. Add long-term raw-log backup to S3. Topology becomes edge -> JetStream -> consumers -> sinks: - Dedicated JetStream NATS cluster (3 replicas, file storage) in the logging namespace. Deliberately separate from app messaging (streamstack) for blast-radius isolation. Stream LOGS (subjects logs.>, retention=limits, 40GiB / 72h) is the outage buffer; durable consumers give independent offsets. - Edge publishers (thin): the k8s DaemonSet and a new VM-ingest Deployment (HTTP NDJSON front door behind the logs-ingest Gateway) publish into JetStream (logs.k8s.<ns>.<container> / logs.vm.<host>). No parsing on the edge. - Transform tier (StatefulSet): pulls the whole stream via the durable `transform` consumer, routes by subject, shapes, and remains the sole ClickHouse writer. Its disk buffer shrinks (JetStream is the outage buffer). - Archiver (Deployment): its OWN durable `archiver` consumer (independent offsets — archive lag never affects the ClickHouse path) writes RAW, pre-transform events to a Ceph RGW S3 bucket (cephrgw-operator ObjectStoreUser + Bucket + BucketAccess) as gzipped NDJSON keyed by raw/<subject>/YYYY/MM/DD/. Default subject filter is Vault audit (logs.k8s.vault.>), configurable. Auth: distinct NATS users (producer publish-only, consumer pull+ack, admin for the stream/consumer bootstrap Job) with passwords from Vault (nats-auth Secret); S3 creds from the BucketAccess Secret. Streams/consumers are provisioned by an idempotent PostSync bootstrap Job. Add local kubeconform schemas for the ceph.unkin.net CRDs (datreeio lacks them) and extend the vector-test CI to cover the agent, VM-ingest and archiver configs. Verified end-to-end locally: NATS ACLs, vector JetStream publish, and durable-consumer pull+ack (at-least-once) all work. Claude-Session: https://claude.ai/code/session_015ur3i7D2azsMAWTSVABApv
