Tagged.Scalar/Sequence/Mapping gain anchor and style fields (Tagged.ScalarStyle, Tagged.CollectionStyle), Tagged.Node gains an alias(anchor:node:) case carrying both the reference and its resolution, and parseTagged populates all of it from the parse events instead of discarding anchors and expanding aliases into copies. PureYAML.dump(_ node: Tagged.Node, options:) re-emits anchors, alias references, tags, and per-node styles over the document-wide policy. Plain scalars re-emit their source spelling (NO stays NO, an empty null stays empty); literal blocks cover keep chomping, single-line strip chomping, leading blank lines, and whitespace-led first lines via an explicit indentation indicator; folded scalars re-emit as > when the folding rules invert exactly and degrade to a literal block otherwise. The round-trip law parseTagged(dump(parseTagged(d))) == parseTagged(d) is corpus-tested over every real-world fixture, with one documented degradation: single-quoted content containing line breaks re-emits double-quoted, value unchanged.
