What and why

The web UI now runs on TanStack Redact (@tanstack/redact, pinned exactly to 0.3.1), a smaller runtime with the React 19 API. The code doesn't change: it still imports from react. The redact() Vite plugin in web/vite.config.ts (placed after react()) points those imports at Redact, both in the build and in vite dev. react/react-dom stay as dependencies for the types, Vitest and Testing Library.

This app is a plain Vite single-page app (TanStack Router), not TanStack Start, so no ssr.noExternal setting is needed.

docs/development.md and the README mention Redact where they name the stack.

Release age: 0.3.1 was less than a day old, so the minimumReleaseAge rule in web/bunfig.toml was skipped once for this manual install, on the maintainer's instruction. bunfig.toml is unchanged, and bun install --frozen-lockfile passes without any flag, so CI is not affected.

Note: crates/agent/tests/daemon.rs playing_on_after_loading_a_version_in_backup_mode_is_no_conflict failed twice during the full workspace run on a machine under heavy load. It passed when run on its own and when its test file was run again. This PR changes no Rust code, so the failure looks like timing flakiness.

Risks checked

Redact renders synchronously; transitions and deferred values do not run concurrently.

• web/src uses none of useTransition, useDeferredValue, startTransition, Suspense, flushSync or createPortal, and has no class components (ApiError extends Error is the only class).
• Radix portals are used in components/ui/dialog.tsx and components/ui/select.tsx. The e2e suites exercise both: the pairing dialog, and the language, mode, default-mode, prefix and target-PC selects.
• @radix-ui/react-dropdown-menu, -switch and -tooltip are dependencies, but no component uses them right now.
• Known bug in Redact 0.3.1: only SVG attributes starting with clip/fill/stroke are hyphenated. web/src has no inline SVG and no Radix Slider. The lucide icons use only stroke*/fill, so this app is not affected.

Rollback

Remove redact() and its import from web/vite.config.ts and drop @tanstack/redact from web/package.json (bun remove @tanstack/redact). The code itself needs no change.
