Research direction

Read routes/session/index.tsx around lines 134–174 and trace how messagesBeforeRevert and messagesFromRevert use the revert boundary. Extract their shared boundary lookup into a helper, then check the session view behavior for cases with and without a matching revert message; done when both functions use the shared lookup and preserve their current results.

Written by the indexing model from the issue text.

Description

Summary

routes/session/index.tsx:134-174 — messagesBeforeRevert and messagesFromRevert both search for the revert boundary — duplicate logic.

Root cause

const messagesBeforeRevert = () => {
  const messageID = session()?.revert?.messageID
  const index = messages().findIndex((message) => message.id === messageID)
  return index === -1 ? messages() : messages().slice(0, index)
}
const messagesFromRevert = () => {
  const messageID = session()?.revert?.messageID
  const index = messages().findIndex((message) => message.id === messageID)
  return index === -1 ? [] : messages().slice(index)
}

Both functions find the revert boundary index independently.

Suggested fix

Extract the revert boundary index lookup into a shared helper.
