📝 Walkthrough

Walkthrough

Die Dokumentation ergänzt eine Mermaid-Darstellung der Input-Handling-Architektur. Sie beschreibt die Handler-Kette, Parsing-Erfolg und Parsing-Fehler, die fachliche Befehlsprüfung sowie Erfolgs- und Fehlerpfade mit UnsupportedCommandError und CommandExecutionError. Zusätzlich beginnt ein eigener Abschnitt „Befehle“.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: 🟡 Moderate · up to eaab0

The diagram currently misrepresents how parse failures proceed, which could lead readers to implement or operate the handler flow incorrectly; merge should wait for this bounded documentation issue and the related label and formatting corrections to be fixed.

In `@docs/src/dse/index.md`:
- Around line 156-157: Update the Mermaid node label for the handler step around
commandHandler.handleOrThrow to use “Rückgabewert” instead of “Rückgabetyp”,
while preserving the existing diagram structure and formatting.
- Around line 161-164: Update the Mermaid outcome labels in the command
execution flow to use the German terms Erfolg and Fehler instead of Success and
Failure, while leaving established identifiers and domain terms unchanged.
- Around line 152-154: Update the Mermaid flow around nodes B and C so node C
first decides whether another handler exists: route the available-handler branch
back to B, and route the no-handler branch to UnsupportedCommandError. Remove
the current unconditional C-to-D edge while preserving the parse-failure path
from B to C.
- Around line 152-163: In the Mermaid flowchart, replace every “</br>”
line-break marker with “<br/>” in the labels around the handler flow, including
the labels for the next handler, thrown error, generated return type, and
command validation.

Für mich passt es so.

Optional könnte man im Pfad can not handle einen Pfeil zurück auf die canHandle-Entscheidung machen, soweit es noch einen weiteren Handler gibt. Gibt es keine Handler mehr, handelt es ich um einen unbekannten Befehl und es wird ein UnsupportedCommandError geworfen

[vjohnslhm]

@ThoGro hab es nochmal überarbeitet und etwas kompakter gemacht:
