cache generations

remote:

Each generation is an immutable directory. Readers lease one for the life of a git subprocess, so warm fetches run concurrently instead of queueing on the writer lock. A retired generation is deleted when its last lease drops; eviction never removes a leased one.

fleet

remote:

Processes that have overwritten nodes/{id}.json within 90 seconds. This is the fleet, not per-repository cache presence. narwal does not query EC2, the ASG, or the ELB.

remote:

The preferred chip is rendezvous::rank for this repository. Any node still accepts a push.

remote:

desired replicas 1: a publish fans prewarm out to the top-ranked peers, and gossips the new index etag to the rest. Both are hints; S3 stays the judge of freshness.

nodes

remote:

A node appears here after it has warmed a cache for this name, and drops off once its presence record goes stale. Presence is a hint, not authority. S3 is.

remote:

A saturated git budget refuses a transfer with a retryable busy rather than queueing it. Eviction removes a repository only when no writer holds it, no lease points at any generation, and it has been idle past the interval.

remote:

narwal does not query the EC2, autoscaling, or load balancer APIs. Instance and target health belong to the ALB and the ASG; this page reports only what the host itself can observe.
