Change

The browser lane's script output is now timestamped line by line, so a line printed by a test's web UI server can be placed against the PASS lines and the job's timings.

• Parallel runner (scripts/ci-browser-parallel.ts, what CI's two browser jobs run): every line written to a script's own log in .ci/browser-logs/ gets an ISO timestamp prefix ([2026-10-23T22:41:05.123Z] …).
  • stdout and stderr are both read line by line.
  • A trailing partial line is kept and written at exit.
  • failureSite() strips the prefix before it looks for the error, so summary.json's failure site and message are unchanged.
• Serial lane (scripts/ci-browser.sh): script output lines get a date -Is prefix.
  • PASS … / FAIL … lines, the TIMING … lines and the summary table keep their exact format.
  • The script's exit code still reaches TIMING and the lane total: the script runs set -euo pipefail, so the pipe keeps it.

Part of #897: its second item (the empty fork-PR failures of 2026-10-06) is an investigation of those runs, not a code change, and stays open.

Checks

• Unit tests: HERDR_TEST_MODE=unit bun test scripts/ci-browser.test.ts scripts/ci-browser-parallel.test.ts: 5 pass, 0 fail.

  • Serial lane (stubbed bun): a server line is prefixed. The PASS/FAIL lines, the TIMING … exit=7 line, the summary row and Browser lane total: … exit=7 are unchanged.
  • Parallel runner: the per-script log lines are prefixed, including a partial last line, and failureSite() still finds the error.

  With the prefixes removed, the parallel test fails.

• bun run typecheck: passes.

• bun run check fast: passes (unit 6259 pass, 0 fail, 13 skip in 444 files, 8 at a time, 58.9s).

• Proof on CI: this PR's own browser jobs are the end-to-end check. Their uploaded browser-logs should show the timestamps.

Outside PRs that touch the same files

The outside PR #1652 (Copilot native chat) also edits scripts/ci-browser.sh and scripts/ci-browser.test.ts and will need a rebase after this one.

No changelog fragment: CI only.

Merge pass. A gate reviewer on a different model than the author's reviewed this CI-tooling change: nothing blocking.

• Tests: ci-browser.test.ts and ci-browser-parallel.test.ts pass (5 tests), and the typecheck passes.
• Serial lane: stderr and partial lines get the prefix, and exit code 7 still reaches TIMING and the lane total.
• Parallel runner: split UTF-8 and all 20,002 records across both streams survive, both on a normal failure and on SIGTERM.
• Failure site: failureSite() still finds the error behind the prefix.

Notes, not blocking:

• In the serial lane, date -Is per line costs about 11 s per 10,000 lines. CI runs the parallel runner instead. A bash printf '%(...)T' would avoid the fork if that lane gets chatty.
• Cross-stream line order isn't guaranteed, which was already true before.

CI: the first run failed one integration test, server/submit.contract.test.ts "sends one held-copy resend across two connections" (its recorder barrier timed out after 5 s). This PR doesn't touch that code; it only changes the browser lane scripts. The re-run of the failed job passed.

CodeRabbit was rate-limited and did not review this PR, so the gate review above stands in for it. All required checks are green and no review thread is open.
