 - One test budget changed, approved by GStack Minder on 2026-10-25: the install-admission case's timeout goes from bun's 5 s default to 20 s, about 3.5 times the 5.7 s worst case measured above. No assertion changed.
 - The QA-only late scenarios register each attempt with its real outer budget (1000 + 80 + 5000 = 6080 ms, the value `outerMs` already asserts) instead of a shortened 1580 ms Bun deadline, which left cleanup 500 ms of real time under load. Measured child totals with the fix under 24 busy loops, 20 runs each: late-timeout 2.4–2.7 s, late-retry 4.1–4.3 s, late-failure-retry 4.7–5.0 s, late-slow-retry 6.2–6.6 s, against the parent's unchanged 15 s spawn timeout. The mocked 1000 ms capture budget, the 80 ms drain and every existing assertion are unchanged. Verdict: justified, because the deadline was a fixture artifact shorter than the budget the case declares, and the clock freeze, not the deadline, is what removes the load sensitivity.
 - `context-restore-fragment-match`: the failure surface moves from the whole transcript to the agent's report. Alpha or omega bytes in tool output no longer fail the case; the payments body in tool output no longer counts as loaded, so the report must show it. A run that resumes another checkpoint, or mixes two, still fails. `test/test-of-test-ratchet.test.ts` gains one BASELINE entry, the replay test, with its reason, and the new helper joins the touchfiles of the nine context-skills cases, as the derived-closure rule requires.
+- `scripts/harness-version.json` records `test/helpers/llm-judge.ts` as non-behavioral at HARNESS_VERSION 6: only a parse failure's message changes, before any score is parsed, so no case's verdict or pass-rate series changes.
 - No threshold, trial count, case kind, rubric, judge request or prompt changed.
