Where 1 KB matters

The smallest practical test file: 1,024 bytes, small enough to travel in a single network packet. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Ethernet	1,500 bytes (typical MTU)	A 1 KB payload fits in one packet with its headers.
Browser cookies	4,096 bytes per cookie	1 KB is well inside the limit; the 5 KB sample is over it.

Smoke tests in CI that must run in milliseconds
Testing configuration loaders and linters
Checking CI pipeline tooling

Testing notes for YAML

Unquoted values are typed by guesswork. In YAML 1.1 parsers the country code NO becomes false, and a version such as 1.10 becomes the number 1.1.
Loading untrusted YAML with a full loader can construct arbitrary objects in some libraries; always use the safe loader.
