Use the validated DOM's character-data key names for both identity and
prototype omission. Replace first-child reinterpretation with canonical,
collision-free aliases inside the pinned decoder boundary; restore names
through the existing dictionary projection. Alias every spelling of the
same name to preserve duplicate assignment order. Handle empty key spellings
and keep scalar key elements outside aliasing. Preserve value text and bytes.
Adapt @thangldw's tests and proposal from PR #3426. Avoid the proposal's
closing-content scanner and re-escaping source names. Add duplicate, empty,
alias-collision, scalar-key, native fallback and Interface Builder controls.
Validation: 180 focused checks across 20 files pass, including built CLI and
actual stdio MCP, build, check:fast and docs:check. Baseline public inspection
truncates main to ma. 24 tiny completed CLI cost controls preserve ordinary
XML/binary full replies and Evidence IDs byte for byte. No statistical speed
claim, heavy profiling, investigated-target or real deep-provider execution.
