token cost
How does the wording change tokenizer units for the declared tokenizer population?
token_delta · deterministic cost
← replace(old=…, new=…) — which thing leaves, and which takes its place?
Archived reported result
Current-tokenizer cost (Δ, worst tokenizer)
0.75 tokens on the named current tokenizer(s) compared with standard English
Reported interval: -3.75 to 0.75
No server-replayable interval attestation is retained for this row; these reported bounds do not acquire settlement weight merely by overlapping.
This historical number is not active evidence for or against the proposal. Read the current status and explanation above.
Protocol key token_delta · Δ tokens
- Is this result within the cost allowance?
- This headline is outside the allowance.
The reported difference is 0.75 tokens; the current declaration allows at most 0 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?
- Inactive history.
This is inactive history. Its reported value is preserved, but it cannot currently support or oppose inclusion.
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. This historical row does not count.
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.

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.

Declared contrast: token_delta
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 1–4 of 4 readable, inline study items, in stored order—not a selection of successes. 0 control items are kept separate.
Input 1
- English input
- Remove the active key from its current role and put the backup key in that role instead.
- Ainglish input
- replace(old=active-key, new=backup-key).
Input 2
- English input
- It is required that parser version 2 cease to be the active parser and parser version 3 become active instead.
- Ainglish input
- replace(old=parser-v2, new=parser-v3).
Input 3
- English input
- Nia proposes removing pump A from the scoped position and installing pump B there.
- Ainglish input
- proposal-by(Nia): replace(old=pump-A, new=pump-B).
Input 4
- English input
- Swap the departing reference for the incoming one.
- Ainglish input
- replace(old=ref-old, new=ref-new).

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.
How to read this receipt
Historical value
This is inactive history. Its reported value is preserved, but it cannot currently support or oppose inclusion.
A token result is not a comprehension result, and current tokenizers may favour English seen during training.Inactive history
This is inactive history. Its reported value is preserved, but it cannot currently support or oppose inclusion.
Read the public explanation and any corrected successor. Do not replicate this as an active original.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 4 complete pairs on 2026-09-05 15:10 UTC. The JSON receipt names the exact verifier and vocabulary checksums. This checks arithmetic, not the fairness of the English comparison.
