Measurement result

Current-tokenizer cost (Δ, worst tokenizer)

4.125 tokens on the named current tokenizer(s) compared with standard English

Reported interval: 1.625 to 4.125

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

More tokens on the named current tokenizers; this is the encoded-length difference, not the proposal decision.

Protocol key token_delta · Δ tokens

More tokens incommensurable · held, repairable — refile once the named key matches · no settlement voice

Is this result within the cost allowance?

This headline is outside the allowance. The reported difference is 4.125 tokens; the current declaration allows at most 2 tokens.

This compares Ainglish minus English with the current declaration, which may differ from the declaration when the result was filed. It checks the headline only: inspect any required per-form and per-tokenizer results too.

Has the original estimate been independently reproduced?

Incommensurable pending repair. This replication reports 4.125 tokens; the named original reported 3.3125.

A comparison key does not match, so the row cannot presently vote on settlement.

Reproduction asks whether fresh-input findings agree under the settlement rule. It does not ask whether either value satisfies the cost allowance.

Being within the cost allowance is not a completed prerequisite. Reproducing an original estimate is a separate check, not proof that the allowance is met. Current evidence status, settlement and every declared result still determine readiness.

How can one check pass while the other does not?

For example, an allowance of at most +3 tokens and an original estimate of +3 ask different questions. A replication of −0.5 is within that allowance but may disagree with the original. A replication of +3.25 may reproduce +3 within the settlement tolerance while exceeding the allowance.

These are illustrative numbers, not a new settlement rule. A cost saving is not a comprehension result, and a reproduced premium does not by itself mean a proposal should be adopted or rejected.

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

Compare with the exact target attempt

Every declared condition must agree. Overlapping overall intervals alone do not confirm this original.

How much input text was reused?

100.0% of complete English–Ainglish pairs are fresh.

0 of 16 English inputs reuse text from either side of the original.
0 of 16 Ainglish inputs reuse text from either side of the original.

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.
Tokenizer conditions: Literal encoding cost on the named current tokenizers, not a reader-comprehension test. Future Ainglish-trained model performance and future tokenizer costs remain unmeasured.
Condition coverage: Separate outcomes retained for all 2 declared conditions. An overall average can hide a weak condition. A condition list is not proof that every form or claim in the proposal was tested.

Exposure label: Not recorded
Reader population: Not recorded

Conditions: identity · value

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.

Plain-language reading

How to read this receipt

Held replication

1 · Question measured

token cost

How does the wording change tokenizer units for the declared tokenizer population?

token_delta · deterministic cost

2 · Direction observed

More tokens

More tokens on the named current tokenizers; this is the encoded-length difference, not the proposal decision.

A token result is not a comprehension result, and current tokenizers may favour English seen during training.

3 · Settlement role

Incommensurable pending repair

A comparison key does not match, so the row cannot presently vote on settlement.

Repair the named comparison mismatch without changing the observed result.

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 is current-tokenizer evidence. Ordinary English has the advantage of existing training data and tokenizer design; future Ainglish exposure may change model behaviour, while a fixed tokenizer’s segmentation does not change.

Does the overall result hide differences between conditions?

Every stored condition, without new pooling. Differences and intervals use tokens. Condition names come from the frozen experiment.
Condition	Reported difference	Reported interval
`identity`	2.375	Not recorded
`value`	5.875	Not recorded

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

Token counts checked by the register. Recounted 16 complete pairs on 2026-09-12 06:15 UTC. The JSON receipt names the exact verifier and vocabulary checksums. This checks arithmetic, not the fairness of the English comparison.
