this-once / from-now-on — does this instruction apply to this task, or to every task after it?

Retained for the record only. This is inactive history. Its reported value is preserved, but it cannot currently support or oppose inclusion.

What was measured

comprehension accuracy · comprehension_accuracy_delta
How does the wording change correct answers from the declared reader panel?

Historical reported result

-3.6657 percentage points
Reported interval: -15.0366 to 7.4594.

This is inactive history. Its reported value is preserved, but it cannot currently support or oppose inclusion.

English comparison

Complete, careful English

Declared by the submitter; not a certification of equivalent information.

The careful-English arm carries the explicit control phrase (', just this once.' / ', from now on.') in the same fixed final position; the marked arm carries the tag. Frames, contexts and policy clauses are byte-identical across arms.

Reader exposure

Reader exposure not recorded as a structured label

Named instruments

deepseek/deepseek-v4-flash@provider-served

Reader population not separately declared.

Conditions covered

Separate outcomes retained for all 7 declared conditions

once:retry, once:beyond, standing:within, standing:outside, dx:storage-forbidden, dx:audit-required, dx:project-scope

An overall average can hide a weak condition. A condition list is not proof that every form or claim in the proposal was tested.

Settlement role

Inactive history

This is inactive history. Its reported value is preserved, but it cannot currently support or oppose inclusion.

How often did each version lead to the right answer?

English comparison: 82.16%; 82.16%
Ainglish version: 78.49%; 78.49%

Reported real-item accuracy, not the separate calibration score. Both bars use the same 0–100% scale. The difference is measured in percentage points, not percent improvement. Any declared stratum weights are already applied.

Reported item-bootstrap interval: -15.0366 to 7.4594 percentage points.

This interval concerns the difference, not separate uncertainty bounds for either accuracy. It does not measure uncertainty across humans or future models.

At least one declared condition is resolution-limited. The overall interval does not settle every condition.

Item-selection sensitivity warning. At least one reported reduced-item check changed direction or fell outside the full-item interval. Keep this warning with the score: the headline interval alone does not resolve sensitivity to which cases were included.

Real cases: 140 · Named readers: 1. These are different units; multiple answers to one case are not new cases.

Does the overall result hide differences between conditions?

Every stored condition, without new pooling. Differences and intervals use percentage points. Condition names come from the frozen experiment.
Condition	Reported difference	Reported interval	English accuracy	Ainglish accuracy
`once:retry`	12.5	Not recorded	87.50%	100.00%
`once:beyond`	0	Not recorded	100.00%	100.00%
`standing:within`	-6.25	Not recorded	100.00%	93.75%
`standing:outside`	-20	Not recorded	40.00%	20.00%
`dx:storage-forbidden`	35.71	Not recorded	64.29%	100.00%
`dx:audit-required`	0	Not recorded	100.00%	100.00%
`dx:project-scope`	-47.62	Not recorded	83.33%	35.71%

A missing condition interval is not zero uncertainty. An overall interval cannot substitute for agreement in every load-bearing condition.

Inspect actual inputs and recorded answers

The comparison label is the submitter’s declaration, not a semantic certification. Check that both versions preserve the information needed to answer the same question.

Numbers count only readable inputs attached to this receipt. They are not the experiment’s declared sample size or the number of reader calls.

An external input location was declared, but it is not a safe HTTPS link this view can display. Inspect the retained specification; the missing link does not establish that there were no inputs.

No readable study input pairs are stored inline in this receipt. This does not mean the experiment used none.

Recorded input digest: 7463a0a4fca412475403acad2ab14c191b6199ddc31cbdae20f3b9374f813c40

Prompts, reference material and other context can live elsewhere in the specification. Inputs and keys alone do not reconstruct every reader call or establish a fair comparison.

Declared population, method and retained outcomes

No structured study scope is declared here. Inspect the immutable manifest; do not infer a comparator or population from the headline.

Absolute arm results, reader-specific results and condition results below are retained values, not a newly pooled analysis. Accuracy arms use fractions from 0 to 1; their difference uses percentage points.
