Documentation changes belong in the LibreChat documentation repository.

Summary

The pane run atoms (submissionStartFamily for the elapsed indicator, showStopButtonByIndex, abortScrollFamily) are already Jotai, but they live in the app store (client/src/store/generation.ts), so every chat hook and component that reads them still imports from ~/store, which the chat package is meant to stop doing.

This moves them into the chat package's React entry (packages/chat/src/react/generation.ts, exported from @librechat/chat/react) with their spec, and points every consumer at it: the SSE and chat hooks, useClearStates, ChatForm, Elapsed and their specs. jotai becomes a peer (and dev) dependency of @librechat/chat, as the React bindings need. The abort-scroll latch drops its debug log line, since the package has no access to the app logger; nothing else changes.

Type of change

• Refactor

Testing

Tested environments/configuration:

Not applicable: same atoms, same defaults, same writes; only where they are declared moves.

Automated tests:

• generation.spec.ts moved to packages/chat/src/react/__tests__/ unchanged (3 pass).
• In client: hooks/SSE, hooks/Chat, hooks/Config, Elapsed and the ChatForm specs: 64 suites, 1,661 tests pass.
• npx tsc --noEmit in packages/chat and client, eslint, prettier, sort-imports: clean. The lockfile change is the two jotai entries for @librechat/chat only, with no internal registry URLs.

Screenshots / recordings

No user-facing change.

Risk / compatibility

#17121 adds the same jotai peer and dev entries to @librechat/chat; the lines are identical, so whichever lands second merges cleanly or keeps one copy.

Checklist

• I reviewed my own changes
• Relevant tests have been added or updated
• Existing relevant tests pass
• The change does not introduce new warnings or errors
