## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The board UI, plugin examples, and plugin SDK all share the same
React dependency graph.
> - Dependabot PR #8471 raised `react` and `@types/react`, but left
`react-dom` and `@types/react-dom` on older 19.x ranges.
> - That let dependency resolution install incompatible React runtime
versions, which makes React refuse to run and breaks UI-oriented test
suites.
> - Current PR policy keeps `pnpm-lock.yaml` owned by CI for
non-dependabot authors, so this PR updates manifests and lets CI
regenerate the lockfile artifact.
> - This pull request replaces #8471 with a complete React toolchain
alignment across the package manifests it touched.
> - The benefit is a single React 19.2.7 runtime graph that keeps
dependency consumers from deduping onto a stale `react-dom` patch.
## Linked Issues or Issue Description
Refs #8471
This PR replaces #8471, which updated `react` and `@types/react` but
left `react-dom` and `@types/react-dom` behind. The resulting dependency
graph can install mismatched `react` and `react-dom` versions, producing
React's incompatible-version runtime error in UI tests.
## What Changed
- Aligned `react-dom` package ranges to `^19.2.7` anywhere the React
dependency set is present.
- Aligned `@types/react-dom` package ranges to the 19.2 line.
- Kept the `react@^19.2.7` and `@types/react@^19.2.17` bumps from #8471.
- Added root pnpm overrides for `react` and `react-dom` so peer-only
consumers resolve to the same 19.2.7 runtime instead of a stale patch.
- Left `pnpm-lock.yaml` out of the PR, per the PR workflow policy; CI
regenerates and shares the lockfile artifact when manifests change.
## Verification
- `cd ui && NODE_ENV=test npx vitest run` passed locally before handoff:
243 files / 1739 tests.
- `NODE_ENV=development pnpm install --lockfile-only --ignore-scripts
--no-frozen-lockfile` passed locally on the rebased branch.
- Confirmed regenerated `pnpm-lock.yaml` resolves `react` and
`react-dom` to 19.2.7 and contains no `react@19.2.4` /
`react-dom@19.2.4` entries.
- GitHub Actions are green on this PR, including `policy`, `Typecheck +
Release Registry`, all general test shards, `Build`, `e2e`, and
`verify`.
- Greptile completed at 5/5 with zero unresolved threads.
## Risks
Low risk. This is a dependency-version alignment only, but React
dependency changes can expose package-manager resolution issues. The
root overrides intentionally constrain the React runtime pair to the
same patch version to avoid that class of failure.
## Model Used
OpenAI Codex based on GPT-5, using command-line tool execution and
GitHub CLI operations in a Paperclip-managed workspace.
