Flaky test: audit-fixes 'TimeoutError carries the configured timeout' fails ~1/N runs

[productdevbook]

Summary

test/audit-fixes.test.ts > TimeoutError carries the configured timeout has been intermittently failing across multiple test-coverage cycles (5, 6, 7). It passes in isolation and on most full-suite runs, but fails roughly 1 in N times when the suite is under load.

Notes

• Reproduces only in full-suite pnpm test runs, not when the file is run alone.
• Likely a timing-sensitive assertion — the timeoutMs window may be undersized relative to the host's scheduling jitter when the test runner is saturated.
• Has been observed and noted in PRs test(transfer): branch coverage >=80% on src/transfer #117, test(stream): branch coverage >=80% on src/stream #118, test(hedge): branch coverage >=80% on src/hedge + fix dangling rejection #119 review notes but not previously filed as a tracking issue.

Suggested fix

• Inspect the test for an assertion that compares an observed elapsed time against the configured timeoutMs. Either widen the tolerance or pin the timeout via vi.useFakeTimers().
• Alternatively, add a retry annotation (it.retry(2)) if the underlying behavior is correct and only the timing is flaky.

Filed during cycle 7 hedge-coverage review (PR #119).
