Symptom → error layer
Creator · Storage · CMS · MCP

When something breaks: don’t guess - use the table below to see which “room” failed, then open the right lesson.

Learning goals: Quickly map symptom → layer → related AS / X lesson.

Previous: AS01 or AS17 · Time: look up when needed

1. Fast triage questions

Routes table check for 404 or blank-page symptoms
Routes layer
Error visible on UI / URL? → Creator (AS04, A03)
Form / data / “Try again later”? → Storage (AS03, X06)
Publishing /cms / content permissions? → CMS (AS07-AS12, AS19-AS21, X11)
IDE / token / zip? → MCP (AS14-AS16, X09, X13)

3. How to use the table

  • Fix one layer at a time - less confusion.
  • Always ask: “Did someone Save changes?” before blaming Storage or CMS.
  • Don’t ask AI to “turn off protection / bypass” when permissions reject you.

5. Checklist

  1. Can you pick the right “Likely layer” for your last 3 issues?
  2. Do you open the matching AS/X lesson instead of fixing at random?

Aura series

AS01 → AS21

Use AS17 before every customer handoff · AS19-AS21 when using CMS + AI / custom types · return to AS01 to review the four layers.
