The core thesis
Vango/Rhone is a platform for making state explicit: who owns it, who can mutate it, how durable it is, and what happens during deploy, scale, wake, rollback, region failure, and host maintenance.
Authority
Control-plane records beat logs, caches, and late worker reports.
Continuity
Live sessions stay pinned unless durable resume proves otherwise.
Honesty
Cold deploys, unsafe replay, data risk, and blocked readiness are product facts.
How To Use This
Use it like a course, not a wiki.
Learn one model
Open Guided Mode and finish one lesson end to end.
Run the matching lab
Flip inputs until you can predict the platform decision before it changes.
Explain it back
Use the quiz prompt and say the answer out loud in terms of owner, writer, durability, and failure.
Use references only after
Taxonomy, objects, traces, events, and runbooks are lookup tools once the lesson gives you the frame.
Architecture Map
The app teaches three connected loops: Vango runtime authority, Rhone deploy authority, and runtime scaling authority.
Vango runtime loop
The app-authoring model
Rhone deploy loop
The release-safety model
Runtime scaling loop
The operations model
Guided Path
Each lesson teaches the concept, walks a trace, gives you an exercise, and then shows what a strong answer includes.
Stateful Does Not Mean Magic
You can explain where Vango session state lives, what survives failure, and why Rhone must be honest about lifecycle.
Foundational
Deploy Safety Is Two Separate Questions
You can distinguish Vango warm/cold impact from database migration safety and explain why rollback is not one button.
Core
Horizontal Scale Is Not One Big Server
You can explain sticky sessions, durable resume, broadcast fanout, and why Rhone blocks scale without runtime services.
Advanced
Wake Semantics Depend On Request Class
You can classify safe wake-and-hold requests versus unsafe replay requests.
Core
NATS Events Propagate Truth
You can explain subjects, streams, durable consumers, snapshots, replay gaps, and why the database remains authority.
Advanced
Stateless Usually Means State Moved Elsewhere
You can explain the stateful/stateless thesis as state placement, ownership, durability, and lifecycle rather than a slogan.
Foundational
Recovery Has Two Axes: RPO And RTO
You can use RPO and RTO correctly and assign different recovery promises to different Rhone data classes.
Core
Vertical Upgrades Are Replacement Plus Drain
You can explain vertical scale, warm replacement, host OS upgrades, and why active sessions usually drain rather than move.
Core
Multi-Region Is Data And Runtime Topology
You can explain why multi-region placement is not just DNS and why live sessions are region-pinned by default.
