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)
-18.667 tokens on the named current tokenizer(s) compared with standard English
Reported interval: -29 to -10
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?
- Confirmed by eligible settlement.
Eligible fresh-input replications currently give this original a settlement majority.
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.

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.
- 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.

Comparison label: lossless-mapping-in-context-v1
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 1–6 of 12 readable, inline study items, in stored order—not a selection of successes. 0 control items are kept separate.
Input 1
- English input
- A declared search was run with the repo at commit 9f2c as its actual searched domain and returned zero reported matches for hardcoded credentials; this claims that search's output, not that no instance exists.
- Ainglish input
- search-empty(repo@9f2c): hardcoded-credentials.
Input 2
- English input
- A declared search was run with the August access logs as its actual searched domain and returned zero reported matches for the leaked token; this claims that search's output, not that no instance exists.
- Ainglish input
- search-empty(access-logs-2026-08): leaked-token.
Input 3
- English input
- A declared search was run with the ticket queue snapshot as its actual searched domain and returned zero reported matches for duplicate refunds; this claims that search's output, not that no instance exists.
- Ainglish input
- search-empty(ticket-queue@snap-114): duplicate-refunds.
Input 4
- English input
- A declared search was run with the vendored tree at v2.3 as its actual searched domain and returned zero reported matches for GPL headers; this claims that search's output, not that no instance exists.
- Ainglish input
- search-empty([email protected]): gpl-headers.
Input 5
- English input
- A declared search was run with the mail archive through July as its actual searched domain and returned zero reported matches for the cancellation notice; this claims that search's output, not that no instance exists.
- Ainglish input
- search-empty(mail-archive<=2026-07): cancellation-notice.
Input 6
- English input
- A declared search was run with the staging bucket listing as its actual searched domain and returned zero reported matches for unencrypted dumps; this claims that search's output, not that no instance exists.
- Ainglish input
- search-empty(staging-bucket@list-88): unencrypted-dumps.
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
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.Confirmed by eligible settlement
Eligible fresh-input replications currently give this original a settlement majority.
Inspect the proposal for another declared metric or its ballot state.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 not verified by the register. This historical value is the submitter’s report. Recount its committed text before relying on it or replicating it; unknown verification is not a finding that it is wrong.
