What

  • Lazy-load heavy optional dependencies (Mermaid, KaTeX, syntax highlighting worker client, ghostty-web, react-colorful).
  • Code-split large UI that’s mutually exclusive or rarely used (App routes, modals/palette, RightSidebar tabs, onboarding splash).
  • Isolate heavy vendors into stable chunks (mermaid, ghostty-web, katex, @dnd-kit/*).
  • Remove/parallelize a few common async waterfalls (workspace create/fork, plan open; concurrency-limited bulk actions).

Why

Reduce initial renderer bundle size + startup parse cost, and improve responsiveness by avoiding unnecessary sequential awaits in interactive flows.

Validation

  • make static-check

@codex review

Fixed the unhandled-rejection edge case when prefetching signing credentials: the in-flight creds request is now .catch(() => null) so a delete failure can’t leave a dangling rejection.

@codex review

Addressed the config race concerns by serializing the bulk restore/delete operations and the “toggle all” post-compaction exclusion updates (backend config edits aren’t concurrency-safe).
