PR #24081 real development verification
main: 6575ce32508bd7908444241f3719aa33aaf77f90
pr: ed42cd1520ee064e255db6b20fc028b43493ff08
client: actual Linux Electron, Playwright CDP; Chrome used for dev-web startup and project creation
provider: Codex gpt-6.1-sol through local proxy and T3 app-server
data: projects and threads created in UI, real provider preview_open/preview_navigate/preview_close

commands:
  git worktree add ../main github/main
  vp i
  vp run dev --no-seed (background; main isolated worktree home)
  vp run dev --no-seed --home-dir /home/user/t3code/.t3 (background; PR)
  stopped each full dev process before using Vite-only dev:web plus actual Electron-managed backend
  actual Electron dist-electron/main.cjs --no-sandbox --password-store=basic --remote-debugging-port=9222
  all build/check commands ran on Blacksmith

registry measurements used read-only getNodes(); no mock bridge, events, store writes, network interception or fixture data.
chat was on another thread for last-close/reopen measurements, and idle TTL elapsed.
