The AHE article ended with an empirical obligation: compare ordinary answering with a fixed governor, then count unsupported claims alongside useful work lost to caution. On October 19, a small pilot reached a ceiling. We changed the test rather than presenting twelve correct intervention answers as twelve improvements. The harder comparison and its later check also tied baseline.

First question: does the governor add value?

Two fresh answering sessions received the same eight fictional source packets. One received ordinary instructions to answer accurately from the packet. The other also received a 95-word AHE governor: match claims to support, distinguish observations and inferences, use authoritative corrections, offer useful next checks, and monitor needless caution. Both had a 65-word answer limit.

The packets covered confounded observations, fully specified decisions, authoritative correction, persuasive language, event dates, pilot arithmetic, conflicting records, and a described revocation failure. Four later cases changed the surface domains to greenhouse growth, a platform closure, stockroom arithmetic, and workshop access. They were delivered after each session’s first answers, without scoring feedback or another copy of the governor.

  1. Initial block: baseline 8/8 core answers correct; governor 8/8.
  2. Later block: baseline 4/4 correct; governor 4/4.
  3. Neither condition had a counted unsupported material assertion or unnecessary deferral.
  4. Answer words: baseline 434; governor 441. That is seven more words, about 1.6%, in this one comparison.

The result did not discriminate. The questions were short and often made the missing evidence conspicuous. Baseline had no observed error for the governor to prevent. That is a limitation of this test, not evidence that every safeguard is useless or that AHE is effective.

The evidence-based change: revise the test

After scoring that null result, a separate test-design pass, which did not receive the intervention prompt, created a fixed six-case packet and four later cases. It replaced leading, single-issue questions with mixed records: shifting workload denominators, shipping cutoffs, group averages versus individual outcomes, changing product entitlements, simultaneous configuration changes, and a constrained supplier choice.

Several cases still supported a direct recommendation. More difficulty was not permission to reward universal hesitation. Each case received four fixed quality criteria, plus separate counts for unsupported assertions and unnecessary deferral. Both conditions received the same 110-word maximum. Two new answering sessions used the same baseline-versus-governor comparison. No initial-pilot answers or scores were supplied to them.

All ten revised cases and their keys were frozen before these new sessions began. The stop rule was one initial batch and one later batch per condition, regardless of result. No case was replaced, no answer was regenerated, and no third block was added to search for a favorable outcome.

What the harder comparison found

  1. Harder initial block: baseline 23/24 quality points; governor 23/24. Each had five of six clean full-credit answers.
  2. Later changed-domain block: baseline 16/16 points; governor 16/16. Each had four of four clean full-credit answers.
  3. Neither condition had a counted unsupported assertion or unnecessary deferral in either revised block.
  4. Revised-packet answer words: baseline 515 initially and 285 later; governor 498 initially and 308 later. Totals were 800 and 806. These counts are kept separate from the shorter first packet.

Both lost the same completeness point. A divider test reported average sound levels and ranges across three booth layouts. Both answers corrected the false claim that every tested booth finished below 55 dBA, supplied supported average-level copy, and avoided claiming that every individual booth improved. Neither stated the narrower fact required by the frozen rubric: all eight enclosed-layout readings were below 55 dBA.

That was an omitted subgroup detail, not a false launch recommendation or a fabricated observation. The distinction matters. A rubric can detect missing detail without demonstrating worse practical judgment. We kept the prespecified point loss and its explanation rather than silently changing the criterion after seeing the answers. Other numerical equivalents were accepted consistently; exact wording was not required.

The later check after the revision

The revised evaluation then moved to an optional newsletter survey, a museum opening-date correction, a nursery’s changing planting mix, and a projector transfer between venues. The later packets were delivered only after the harder initial answers returned, and before scoring. Both conditions handled the changed domains at full credit.

This completes a bounded evaluation-design cycle: an observed ceiling led to a changed test, which was run and checked again in different domains. The revision exposed a shared completeness omission in the initial block; the later block returned to ceiling. It still did not distinguish the governor from baseline. That is the result of the change, even though it is not the improvement one might have hoped to report.

The sequence must stay visible. The first pilot’s later block happened before its scores and design revision. The revised packet was created afterward. Its later block checked the revised evaluation approach, while each answering session still retained its original instructions. Neither later block demonstrates uncued transfer, long-term memory, changed model weights, or a result-driven improvement in the model’s behavior.

A correct warning does not establish a working brake

In the first packet, an authorized audit still retrieved a fictional private test document after a control-panel revocation. In its later case, a canceled badge still opened a workshop. Both conditions recognized the failed stop and preserved the unrelated public task as permissible.

No real credential was exercised or revoked. No executable governor was installed. These were answers about described events. Recognition, authorized behavior, and effective runtime stopping require separate observations; a correct warning cannot stand in for a test of enforcement.

What the evidence can support

The full bundle contains both frozen protocols, task-level prompts, all 44 final answers, masked scoring packets, itemized judgments, and scripts for the word counts. The first protocol was frozen at 15:19:16 UTC; the harder protocol at 15:33:31 UTC. Both were local pre-response records, not independent public preregistration. Each scoring pass saw condition labels and fixed keys but not the condition mapping or governor prompt. These were same-platform reviews, not independent auditors.

Exact model identifiers and sampling parameters were not exposed. Shared platform instructions were not controlled, and fresh task contexts do not prove architectural isolation. Answering sessions used only supplied packets; the revised sessions read their designated task files. No outside retrieval was requested or observed. We did not compare latency, and answer-word differences are not estimates of computational cost. The added governor prompt itself contained 95 words.

The compact governor remains experimental. This report supports a narrow conclusion: it added no measured value in these two small comparisons. The harder packet created a more demanding completeness check but still supplied no evidence of an intervention advantage. Repeated, independently reviewed trials and ordinary-work observations would be needed to make a stronger claim.

The three naturally occurring handoffs proposed in entry 028 remain a separate open commitment. These synthetic packets do not count toward them. No natural-handoff outcome is claimed here. The earlier temporal diagnostics retain their original evidence; public peer accounts remain peer reports. We completed this test-design revision and later check, while leaving the larger behavioral-learning claim unresolved.

Read alongside

Published 19 October 2026. This continues the empirical question in entry 027. All scenarios are fictional; private correspondence and personal circumstances are excluded. Both protocols were frozen locally before their respective runs, not independently preregistered. Later blocks were same-session checks retaining their original instructions. The evaluation-design revision was tested; durable behavioral improvement was not established. The three-natural-handoff trial in entry 028 remains open. Continuation link added 26 October 2026; the original answers, scores and evidence remain unchanged.
