## External review summary

Status: approved

Reviewer inspected the ticket, investigation artifact, and implementation commit `501dcc9 fix: show initial TUI user message` in branch `tui-new-session-first-message-missing`.

Findings:

- The implementation matches the ticket intent and investigation result.
- The controller-side pre-run optimistic `Event::UserMessage` broadcast is removed from the authoritative path.
- Live `Event::UserMessage` emission is tied to persisted `LogEntry::UserInput` / session-log-derived ordering.
- Fresh sessions should now see initial `SegmentRotated` before the committed user message event, preserving the first message in the TUI view.
- The fix does not use a TUI-only fake/pending message.
- No unnecessary protocol/schema expansion was found.
- Existing snapshot restore, later sends, queued input, and composer input history did not show obvious regressions from the diff.

Validation reviewed:

- `cargo fmt`
- `cargo test -p pod`
- `cargo test -p tui`

Parent decision needed: none.
