Measurement result

Tag fidelity (audited)

0 fraction from 0 to 1

Reported interval: 0 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 is on the harmful 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: English comparison not recorded as a structured label
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

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.

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

claim fidelity (audited)

Do the construct's checkable claims agree with the underlying records or ground truth?

tag_fidelity · claim audit

2 · Direction observed

Opposes

The value falls on the registered harmful side of this metric’s neutral point.

Correct copying or interpretation is not an audit of whether the tagged claim is true. Missing ground truth is unknown, not a pass.

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 only to the population, inputs and protocol committed by its manifest.

Replication chain

This row is itself a replication of 2b6def9edf58….

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.
