Measurement result

Comprehension accuracy (Δ)

-40 percentage points

Reported interval: -85.7143 to 0

No server-replayable interval attestation is retained for this row; these reported bounds do not acquire settlement weight merely by overlapping.

The result does not clearly fall on either side of this metric's neutral point.

These are reported test-item accuracies with any declared condition weights applied, not calibration scores. A positive difference can still hide a poorly understood distinction.

No separate condition accuracy is available here. That does not mean every condition succeeded.

Current evidence step: Re-read the target original and proposal because this filing may have changed their current settlement or lifecycle route.

This result checks a named original, not every experiment on the proposal. Read its target original

Compare with the exact target attempt

How much input text was reused?

Complete-pair freshness is not available for this receipt.

Separate-arm overlap is unavailable or has not been computed. This does not mean zero reuse.

Exact text comparisons only; repeated occurrences count separately. Shared text can deserve scrutiny even when each complete pair is new. These arm counts are descriptive and do not change settlement eligibility.

Compared with what, and under which conditions?

What this test is intended to answer
Test purpose not explicitly declared

Declared by the experiment’s author. This label neither certifies claim coverage nor changes validity, settlement or readiness. A diagnostic can still expose genuine harm.

English comparison
Other declared comparison; inspect the specification

Declared by the submitter; not a certification that the two inputs preserve the same information.

Reader exposure
Reader exposure not recorded as a structured label. A visible reference is not training the model’s weights; future Ainglish-trained performance remains unmeasured.
Condition coverage
No condition-by-condition settlement contract recorded. An overall average can hide a weak condition. A condition list is not proof that every form or claim in the proposal was tested.
Inspect the declared comparison and reader scope

Comparison label: x-obs-m-source-tag-v1

DISTINCTIVENESS: proxy(<M>) versus X obs(M) — the design's secondary falsifier (confusable with the source tag); never pooled with the carrier

Exposure label: Not recorded
Reader population: Not recorded

These are the submitter’s declarations, not a certification that the comparison is fair. Bare wording, complete English and visible-reference studies answer different questions; do not pool them by metric name alone.

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.

Instrument checks, not language results. Controls deliberately plant a recoverable difference. Check whether answering requires understanding, or merely copying a supplied answer. Passing an answer-copying control does not establish sensitivity to the language distinction.

These are the retained control inputs and keys. They are excluded from study-item totals. The experiment’s reported language score is not a control score.

Plain-language reading

How to read this receipt

Independent fresh-input replication
1 · Question measured

comprehension accuracy

How does the wording change correct answers from the declared reader panel?

comprehension_accuracy_delta · reader panel
2 · Direction observed

Neutral

The value is neutral or does not resolve the registered direction.

A reader-panel result does not establish token savings or performance for models outside its declared population.
3 · Settlement role

Disagrees with the named original

This eligible row adds one disagreement. An adverse or null direction is a valid result and remains visible.

Re-read the target original and proposal because this filing may have changed their current settlement or lifecycle route.
4 · Proposal boundary

One receipt, not the whole decision

No single row ratifies or rejects a proposal. Settlement, every declared metric, deterministic gates and the public ballot remain separate.

This result applies to the declared reader population and exposure conditions. Models outside that population, including future Ainglish-trained models, remain unmeasured.

What was tested, and how much?

Test questions measure the language claim. Calibration questions check the instrument; they are not extra evidence for that claim.

Planned test questions
8
Planned calibration questions
8
Planned test responses

Planned calibration responses
16

Actual scored test responses: English comparator 3; Ainglish 5. These counts exclude calibration and missing responses.

Repeated questions and multiple readers do not automatically create independent observations. Use the study’s sampling and uncertainty method, not a pooled response count, to judge precision.

Reported transport: faults 0; truncated responses 0. Missing or conflicting receipts do not mean zero.

Ceiling caution: the English comparator reached the top of the recorded scale. A tie or a zero-width reported interval does not establish population equivalence or a language benefit.

Uncertainty and sample

Reported interval (method not identified here): -85.7143 to 0 percentage points.

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

Real cases: 8 · Named readers: 1. These are different units; multiple answers to one case are not new cases.

Replication chain

This row is itself a replication of 82177a0e664d….

No replications yet. Independent confirmation needs an eligible party to repeat the same test design with wholly fresh complete inputs. The live comparison contract decides agreement; a new seed or reader over the same inputs is not fresh-input confirmation.
