# Runtime transcript, issue #33743

Page: 2,000-row synthetic table from gen_page.py, served at http://127.0.0.1:18961/big/.
Each side: its own checkout's dev server (`T3CODE_DEV_SEED=0 vp run dev:server`, fresh database), one agent turn started with `t3 thread start` (run_side.sh) that calls preview_open then preview_snapshot, and the raw tool result read back from that server's database (extract.py).

## Before: main 4c361199f4
```
$ t3 thread start ... (agent reply)

["visibleText after 0 characters (use preview_evaluate for more)","accessibilityTree after 10000 characters","1 of 1 networkEntries"]
