GitHub PR: https://github.com/pingdotgg/t3code/pull/27266
Head: a4f1bdeb400cc709ae8935a8dc89182b63af53d0 (unchanged)
Baseline: github/main 6d46336476
Environment: Linux Boat VM, repository Playwright 1.60.0, /usr/bin/google-chrome.
Provider: real Codex gpt-6.1-sol through the local proxy.

Created /home/user/trace-verification as a real git repository, added it through
Add project > Local folder, selected GPT-6.1-Sol and sent real provider turns.
Commands pwd and git status --short ran in that project. The client displayed
TRACE_VERIFICATION_OK, TRACE_FOLLOWUP_OK and TRACE_RECORDING_OK, with no file changes.
Reloaded the PR thread and expanded its completed tool activity successfully.

To reach fractional near-second durations without fixtures or fake spans, asked
the real provider to call the T3 MCP t3_thread_wait endpoint on its own active
thread 25 times with timeoutMs=990. Both servers emitted genuine timing spans.
Selected two unchanged lines from the real main trace into /tmp/live-boundary.ndjson.
No span names, durations, timestamps or other fields were modified.

CHECKS:
Blacksmith vp test run apps/server/src/cli/trace.test.ts: 3 passed.
Blacksmith vp run check:changed 80a2351fcb909034e65a512dfabeb3cdfd367762:
format, lint, knip (both passes), graphql, 3 package typechecks, 4 tests passed.
The first check:changed attempt could not find the merge base in the worker shallow
snapshot. Fetched PR history on that worker and reran the unchanged check successfully.
Two independent read-only reviews approved the exact head, with no findings.

NOT VERIFIED:
Packaged executable; native Electron/macOS/Windows and iOS/Android clients;
relay/tunnel connections; providers other than Codex. The diff only changes CLI
formatting, with no client UI, provider adapter or wire contract modifications.
