Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

HOW- Goal
- Define and serialize custom data types with customTags for custom scalar and object schemas in yaml
- Packages
- Created
- 2026-08-18T19:26:52Z
Contract
- assert custom ScalarTag with identify, resolve, and stringify parses !point 10,20 into Point instance and stringifies Point back to tagged scalar
- assert custom ScalarTag for RegExp parses !regexp /pattern/flags string and stringifies RegExp instances with !regexp tag
- assert custom CollectionTag with collection 'seq' parses !vector sequence items and serializes Vector instances into tagged sequence nodes
- assert custom CollectionTag with collection 'map' parses !color mapping entries and serializes Color instances into tagged mapping nodes
- assert custom tag resolve callback onError registers a YAMLParseError when scalar input fails format validation
- assert parseDocument and Document AST constructor accept customTags in SchemaOptions and preserve custom tags in toString and toJS
- assert customTags option accepts a function to transform base schema tags array
