PR 27413 real dev verification, Linux, 2026-11-01 UTC
main: github/main 5732bbee39, /home/user/main
PR: 2553b5ebb8212f54606ce4ab6ff76659acb0d628, /home/user/t3code

Commands:
  git worktree add ../main github/main
  vp i (both checkouts)
  main: setsid nohup timeout 6500 vp run dev --no-seed
  PR: setsid nohup timeout 5700 vp run dev --home-dir /home/user/t3code/.t3 --no-seed
  Chrome: /usr/bin/google-chrome; Playwright 1.60.0 from repo dependencies
  main server stopped by captured process group before PR startup.
  One PR startup initially defaulted to ~/.t3; stopped before browser verification,
  then restarted with explicit isolated home. All reported PR scenarios use .t3.

Data created through the real web UI separately on each version:
  Add project > Local folder > /home/user/snapshot-verification (real git repo)
  Select Codex GPT-6.1-Sol, submit:
  Read README.md using a shell command. Reply with its exact contents. Do not change any files.
  Provider executed cat README.md; both clients displayed: shell snapshot verification

Chrome DevTools Protocol Network timestamps (seconds, browser monotonic clock):
Main, browser reload:
  /ws handshake response, status 101: 944.286246
  GET /api/orchestration/shell?omitIdleSubagents=1&omitOlderSettled=1 starts: 944.321310
  HTTP response status 200: 944.356736
  Shell request starts 35.064 ms AFTER socket opens.
PR, browser reload:
  GET /api/orchestration/shell?omitIdleSubagents=1&omitOlderSettled=1 starts: 1111.411193
  /ws handshake response, status 101: 1111.445360
  HTTP response status 200: 1111.572880
  Shell request starts 34.167 ms BEFORE socket opens.
These prove request ordering through the real client/server path, not an end-to-end speedup claim.

Neighbor: HTTP failure fallback
  Chrome Network.setBlockedURLs blocked */api/orchestration/shell* (no fabricated response).
  Browser reload requested shell HTTP; request failed with blockedReason=inspector.
  Actual outgoing websocket orchestration.subscribeShell payload:
  {"requestCompletionMarker":true,"omitIdleSubagents":true,"omitOlderSettled":true}
  No afterSequence: client requested the full socket snapshot.
  Existing project, conversation and provider output rendered successfully.
  Removed network block afterward.

Neighbor: real server disconnect/reconnect
  Stopped PR dev process group using its captured PID.
  Restarted the same head, port and isolated home; existing browser recovered persisted thread.
  Submitted through composer:
  Read README.md again using a shell command. Reply exactly: reconnect verified: followed by the contents. Do not change files.
  Real Codex GPT-6.1-Sol ran cat and completed:
  reconnect verified: shell snapshot verification
  Shared clip shows the post-restart turn at 2x speed; server startup downtime removed.

Focused checks, via task-owned Blacksmith worker:
  vp i && vp test run packages/client-runtime/src/state/shell-sync.test.ts
  PASS: 1 file, 11 tests, including superseded loads and live/cached config mismatch.
  Worker stopped after checks.
  GitCafe reports 30 successful checks, zero failing/pending, for the exact PR head.

Not verified:
  Native Electron, iOS, Android; macOS/Windows; relay/tunnel; end-to-end reconnect latency savings.
  Superseded route attempts and live/cached capability mismatch covered by focused tests,
  not independently forced in the real client.

No source edits, commits or pushes were needed.
