Principal/Senior-level NATS playbook for subject design, request/reply, JetStream durability, consumer semantics, multi-tenant messaging, and operating lightweight event platforms at scale.
Use when: designing evented systems with NATS, reviewing JetStream usage, tuning subjects and consumers, or operating NATS in production.

NATS Mastery (Senior → Principal)
Operate
Start from messaging semantics: ephemeral pub/sub, request/reply, durable streams, or control-plane signaling.
Treat subject design, consumer semantics, retention, and topology as first-class architecture concerns.
Prefer simple subject hierarchies and explicit delivery semantics.
Design for debuggability and operator clarity before chasing messaging cleverness.
Default Standards
Subject naming should encode bounded, meaningful routing intent.
JetStream retention and ack behavior must match business semantics.
Consumers must be idempotent where durability and replay matter.
Multi-tenant usage needs policy before it needs scale.
Observability should reveal lag, redelivery, and cluster health clearly.
