YAML / scalar / coercion boundary
Review YAML implicit scalar types
Review boolean-like, date-like, numeric, quoted and null scalars as different boundaries. This is a conservative review guide, not a claim about one parser.
Scalar review boundaries
Plain YAML scalars may be interpreted differently by implementations and schemas. Review quoting and the receiver’s type separately.
plain scalar → type review → explicit quote| case | What to review |
|---|---|
boolean-like | Review yes/no and true/false-like values as boolean candidates. |
date-like | Review date-looking text as a possible date value. |
leading-zero-number | Review leading-zero values as strings before numeric conversion. |
quoted-string | Use quoting to make string intent explicit. |
explicit-null | Separate explicit null from an omitted value. |
Review order
- Separate plain scalars from quoted strings.
- Record boundaries that look boolean, date-like or numeric.
- Check the schema and receiver type separately.
- Return ambiguous values for confirmation instead of guessing.
