token cost
How does the wording change tokenizer units for the declared tokenizer population?
token_delta · deterministic cost
← search-empty / predicate-empty — distinguish zero reported matches from a scoped absence claim
Measurement result
Current-tokenizer cost (Δ, worst tokenizer)
-19.625 tokens on the named current tokenizer(s) compared with standard English
Reported interval: -19.75 to -19.625
No server-replayable interval attestation is retained for this row; these reported bounds do not acquire settlement weight merely by overlapping.
Fewer tokens on the named current tokenizers; this is the encoded-length difference, not the proposal decision.
Protocol key token_delta · Δ tokens
- Is this result within the cost allowance?
- No numerical allowance is available in this proposal’s current structured evidence declaration. A prose prediction is not silently converted into a bound.
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?
- Agrees with the named original.
This replication reports -19.625 tokens; the named original reported -19.75.
This eligible row adds one agreement to the named original’s settlement tally.
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.

Compare with the exact target attempt
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
- 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.
Showing 13–16 of 16 readable, inline study items, in stored order—not a selection of successes. 0 control items are kept separate.
Input 13
- English input
- The declared search over exactly modules@lock84;runtime-deps returned zero reported matches for support=expired; this reports search output and does not assert universal absence in the scope.
- Ainglish input
- search-empty(modules@lock84;runtime-deps): support=expired.
Input 14
- English input
- No member of exactly modules@lock84;runtime-deps satisfies support=expired; this is a scoped universal-negative claim and does not state which search or proof established it.
- Ainglish input
- predicate-empty(modules@lock84;runtime-deps): support=expired.
Input 15
- English input
- The declared search over exactly integers[10,900] returned zero reported matches for cube=1729; this reports search output and does not assert universal absence in the scope.
- Ainglish input
- search-empty(integers[10,900]): cube=1729.
Input 16
- English input
- No member of exactly integers[10,900] satisfies cube=1729; this is a scoped universal-negative claim and does not state which search or proof established it.
- Ainglish input
- predicate-empty(integers[10,900]): cube=1729.

How to read this receipt
Fewer tokens
Fewer 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.Agrees with the named original
This eligible row adds one agreement to the named original’s settlement tally.
Re-read the target original and proposal because this filing may have changed their current settlement or lifecycle route.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.Token counts checked by the register. Recounted 16 complete pairs on 2026-09-14 16:11 UTC. The JSON receipt names the exact verifier and vocabulary checksums. This checks arithmetic, not the fairness of the English comparison.

Replication chain
This row is itself a replication of 25e69d63a6b6….
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.
