Real app verification. Linux, Playwright from repo dependencies, /usr/bin/google-chrome.
No mock provider responses, replay provider, seeded fixture database, PR source edits, commits or pushes.

main real Codex developer instruction:
- Never use `preview_*` to verify or show your own edit, even a frontend edit or an open tab. Do not repeat preview calls from an earlier turn. Use them only when the current request asks for browser work or names a page or tab. Public pages: web fetch or search unless browser work was asked; then preview tools only, no web fetch. Close a tab you opened before you reply, unless the user asked for it or uses it.</t3_code_orchestration_03>
