EventReader.next(), both initializers, and the Event alias are public
(an internal typealias in a split file had been shadowing the public
Parsing.Event); a new PureXMLPublicAPITests target compiles without
testable import so facade gaps fail CI. The large-corpus benchmarks
exposed document-order sorting as quadratic on flat fan-outs; the fix's
first attempt was itself worse (an eager sibling table built per
predicate evaluation), caught by sampling the live run, and replaced
with a lazy table: single-node sets never touch order keys and a
parent's table builds on its second lookup. XPath at 42 MB drops
27.1 s to 1.57 s (190x to 11.7x); at 210 MB PureXML completes in 9.4 s
the query libxml2 refuses at its 10M node-set cap (#143 tracks our
configurable budget). Benchmark harness: size series to 210 MB, CORPUS
mode for real files (NASA, SwissProt measured), SAX stage,
refusal-aware table, NULL-safe C driver. All conformance suites,
Linux, and WASM verified. Closes#142.
