### Create Pydantic *models* / schemas for reading / returning

Now create Pydantic *models* (schemas) that will be used when reading data, when returning it from the API.

For example, before creating an item, we don't know what will be the ID assigned to it, but when reading it (when returning it from the API) we will already know its ID.

### Creating the `Settings` only once with `lru_cache`

Reading a file from disk is normally a costly (slow) operation, so you probably want to do it only once and then re-use the same settings object, instead of reading it for each request.

But every time we do:

```Python
Settings()
```

		if stream.Name == "inspect.zip" {
			if extracted {
				return keepFileErr{errors.New("multiple inspect.zip streams found")}
			}
			_, err := io.Copy(w, stream)
			if err != nil {
				return fmt.Errorf("reading inspect stream: %w", err)
			}
			fmt.Println(okMsg)
			extracted = true
			continue
		}
		if err := stream.Skip(); err != nil {
			return fmt.Errorf("stream skip: %w", err)
		}
	}

// for io.EOF.
//
// If an EOF happens after reading some but not all the bytes,
// ReadFile returns ErrUnexpectedEOF.
//
// If the BitrotVerifier is not nil or not verified ReadFile
// tries to verify whether the disk has bitrot.
//
// Additionally ReadFile also starts reading from an offset. ReadFile
// semantics are same as io.ReadFull.

from multiple sources (mesh-level, namespace-level and workload-level).

The command also supports reading from a standalone config dump file with flag -f.`,
