One dev server at a time. Playwright 1.60.0, /usr/bin/google-chrome, 1440x1000.
Project added via UI, real git repo /home/user/t3code. Codex gpt-6.1-sol selected in UI.

Same prompt on each revision:
This is a runtime command-output verification. Do not read files, use skills, change files, or run anything else. Use your shell execution tool once to run this exact command with yield_time_ms=1000, then wait for that same command to complete. Command: timeout 60 sh -c "printf 'A\tB'; sleep 25; printf '\rXY\nA\tB\033[9GX\nabcdefghij\rA\tX\nplain\tvalue\ntrail\t\n[1/3]\r[3/3] done\n\033[31mred\033[0m\n'". After completion reply only 'command complete'. Do not interpret, normalize, replace, or summarize the raw output.

Raw provider completed output (JSON escaped):
"A\tB\rXY\nA\tB\u001b[9GX\nabcdefghij\rA\tX\nplain\tvalue\ntrail\t\n[1/3]\r[3/3] done\n\u001b[31mred\u001b[0m\n"
Exit code 0 on both.

Main command panel text:
"XYB\nA\tB     X\nA\tXdefghij\nplain\tvalue\ntrail\t\n[3/3] done\nred\n"
PR command panel text:
"XY      B\nA       X\nAbcdefghXj\nplain   value\ntrail\n[3/3] done\nred\n"

Reload during turn and after completion succeeded. Final output identical after reload.
Red span computed color rgb(207, 34, 46).

Additional real Codex commands, each exit 0:
printf "A\\tB\\033[1;9HX\\n" => "A       X\n"
printf "abcdefgh\\tX\\n" => "abcdefgh        X\n"

Blacksmith checks: 32/32 focused tests pass (terminalOutput, CommandOutputHub, commandOutput).
vp run check:changed github/main: pass format, lint, knip, affected typechecks, 24 tests.
Worker fetched public PR/main history because initial snapshot had no merge base.
Existing CI: 30 successful, 0 failing, 0 pending.

Unverified: live command output delta normalization. This local proxy Codex session emitted item/completed raw output but no item/commandExecution/outputDelta notifications.
Native desktop/mobile, other providers, macOS/Windows, remote/tunnel paths not exercised.
Custom normalizer budgets greater than 65536 not exercised through app; production callers use default 65536.
No source changes or pushes.
