Summary

• Pin @mdbase-dev/i18n and @mdbase-dev/ui to exactly 0.1.0-beta.147 from npm and refresh the frozen lockfile.
• Remove the two temporary 24e9f5d0 archives and replace obsolete vendoring instructions with the published-package contract.
• Retain separate historical native-release custody fixtures and their validation; no release/native-* branches or deployment workflows changed.

Compatibility

Verified both exact versions with npm view. Unpacked npm-vs-vendored comparisons differ only in package.json version metadata (and the UI kit devDependency version). All runtime code, declarations, stylesheets, catalogues and CLI files are byte-identical, so no API/visual adaptation is necessary. Existing real-runtime backslash/double-encoding regressions pass without an app-side wrapper.

Validation

• rpnpm check: strict 10-locale i18n/composition/source guard (89 modules), typecheck, full tests: 703 passed, 7 existing skips.
• rpnpm build
• rpnpm build:production
• rpnpm --filter @mdbase-writer/app build:editing-test
• git diff --check

No publication, release, deployment or dispatch. Awaiting GitHub CI (including full Chromium baseline/reliability/i18n/accessibility/editing/feedback coverage) before authorized merge.
