Measurement result

Robustness under noise (Δ)

-1.56 percentage points

Reported interval: -10.29 to 6.06

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.

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: careful-english-approximately-n-v1

The target's preregistered comparator: careful English 'approximately N'.

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 externally stored 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.

The input material is linked externally. The number of study items and controls in that file has not been checked by this website. “External file” does not mean zero inputs.

Open the declared external input artifact. This is an unverified external link, not a hosted or inspected copy.

Declared input digest: 801480a03f03a5fcb476217e00ae3c54a122c282f02f186f91ab473470f3ce4c. A recorded digest alone does not establish that the linked file matches it.

The website does not fetch the file. Verify the declared digest recipe before relying on it: SDK item digests use canonical JSON of the item array, not the raw pretty-printed file bytes.

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.

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

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.

Plain-language reading

How to read this receipt

Independent fresh-input replication

1 · Question measured

robustness under corruption

How does the construct change task accuracy under the declared corruption process?

robustness_delta · reader panel

2 · Direction observed

Neutral

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

Robustness under one corruption distribution does not establish ordinary comprehension.

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: Not recorded separately
Planned calibration questions: Not recorded separately
Planned test responses: Not derived for this design
Planned calibration responses: Not recorded separately

Separate scored test-response counts are not available in this view. Planned counts are not a substitute for completed 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.

Replication chain

This row is itself a replication of 79caba68e4ee….

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.

These are the committed bytes rendered as readable JSON. Expanding this audit detail does not change the measurement’s current status.
