Fixes #3933. Part of #4027. Normalize exact literals and configuration defaults through the shared primitive owner. Preserve tagged limits through member/destructuring projection and record encountered bounds in per-analysis state independently of later selected values. Remove the retained-value rescan and duplicate default reader. Preserve source Evidence, bounded/null values, aggregate wire capacity and complete endpoint lookup identities for query/trace/comparison. Validated 66 focused and 932 semantic tests on the restored identical runtime; final public selection 7/7 adds an augmented large-endpoint acceptance (67 distinct focused cases across invocations). Full static/docs and fresh real Obsidian controls passed. Compact measurements and rejected attempts remain recorded. Co-authored-by: Kaoru0822 <208281322+kaoru0822-kitauji@users.noreply.github.com>
