Its `t3-fork.json` records the exact source commit and upstream base. File/skill link recognition, back navigation from horizontal blocks, table-image presses, and code-block headers use upstream implementations. The remaining fork adds clipboard metadata, parsed asset manifests, signed image source resolution, React media slots, and development-host autolinks.

Its `t3-fork.json` records the exact source commit and upstream base.

The fork retains clipboard metadata, parsed asset manifests, signed image source resolution, React media slots, and development-host autolinks. The fork retains native math parsing, scrolling and copying, table layout and gestures, and inline-code layout. Character-reference decoding, iOS intrinsic-width measurement, and HTML clipboard round trips now use the upstream fixes included in Julius's base. RaTeX uses the upstream-released 0.1.15 dependency.

+To replace it, commit the fork changes, run `yarn install --immutable` and `yarn workspace react-native-enriched-markdown prepare` in the fork checkout, then `node scripts/pack-t3.mjs /path/to/t3code/apps/mobile/deps`. Keep the package version aligned with Julius's `fork/t3-mobile` branch. Rename the archive to include the first eight characters of the source commit, such as `react-native-enriched-markdown-1.2.0-t3.15-fee84114.tgz`, so each build has a distinct dependency path without version bumps. Update the tarball path in `apps/mobile/package.json` and `pnpm-workspace.yaml`'s `allowBuilds`, and run `vp i` to update the lockfile. Native clients need rebuilding when this dependency changes.
