apps/server/src/terminal/Manager.ts

line 823: append drops a newline-only chunk when the existing history already ends in a newline. For example, appending "\n" to retained "a\n" takes the this.trailingNewline branch with an empty appendedLines array, leaving the value "a\n" rather than "a\n\n". PTY chunk boundaries can split consecutive blank lines this way, so terminal history and persisted/snapshotted output silently lose empty lines. [ Out of scope (triage) ]
