Interpret the validated, depth-bounded DOM directly. Collect source number
facts during the same traversal and share them with keyed archives, Interface
Builder and native plist projections. Remove the second XML parse, key aliases,
source-location rewriting and both duplicate XML numeric scanners. Preserve
character references, container/null behavior, safe own-property construction
and prototype omission accounting.
Decode signed hexadecimal integers and combine real text/CDATA. Retain exact
integer identity when a finite integer exceeds even Number's finite range,
using the shared scalar projector. Keep unsupported mixed integer syntax
conservative and report incomplete metadata.
Adapt @apitoagents's hexadecimal regression and literal-parsing proposal from
PR #3475. Native plutil controls establish the supported hex/real cases and
confirm that the synthetic 401-digit overflow case exceeds native bounds;
retaining accepted input does not claim native-format support.
Validation: 274 focused checks in 30 files pass, one skipped; build,
check:fast and docs:check pass. Built CLI/actual stdio MCP, native plist and
Interface Builder controls cover kinds, references, exact digits and digests.
Eight baseline checks fail; native binary conversion independently verifies
updated CDATA real expectations. 48 tiny completed CLI cost comparisons
preserve ordinary XML/binary and all three native replies byte for byte.
Two read-only reviews clear. No statistical speed claim, heavy profiler,
investigated-target execution or real deep-provider verification.
