Sample
Merge YAML mapping keys with merge option and schema yaml-1.1 using parse and parseDocument

This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- assert YAML.parse with merge option resolves single mapping merge key << from referenced anchor
- assert YAML.parse with merge option overrides merged anchor keys with explicitly defined mapping keys
- assert YAML.parse supports sequence of merge keys with earlier mappings taking precedence over later ones
- assert YAML.parseDocument with merge option or yaml-1.1 schema parses merge keys into AST and resolves them in Document.toJS
- assert YAML.parseDocument preserves merge key AST structure in Document.toString serialization
- assert Document.toJS throws an error when a merge key references a non-mapping scalar or non-mapping sequence item
