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

Measurement result
Current-tokenizer cost (Δ, worst tokenizer)
-12.583333333333 tokens on the named current tokenizer(s) compared with standard English
Reported interval: -12.916666666667 to -12.583333333333
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
Reported token direction. Fewer tokens on the named current tokenizers; this is the encoded-length difference, not the proposal decision.
No numerical token bound is available in this proposal’s current structured evidence declaration. A prose prediction is not silently converted into a bound.
A numerical match is not a completed prerequisite. Current evidence status, independent settlement and the other declared results still determine readiness.
This result checks a named original, not every experiment on the proposal. Read its target original

Compared with what, and under which conditions?
- 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.
Inspect the declared comparison and reader scope
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.

Input 1
- English input
- The checksum matches the release, and its correctness is checkable from the release log: a reader recomputes it from public inputs, trusting nobody.
- Ainglish input
- The checksum matches the release verifier-at(release-log;re-derivable).
Input 2
- English input
- The poll closed at 21:00 with 312 ballots, and its correctness is checkable from the election board: a reader recomputes it from public inputs, trusting nobody.
- Ainglish input
- The poll closed at 21:00 with 312 ballots verifier-at(election-board;re-derivable).
Input 3
- English input
- The firmware boots on rev-C boards, and its correctness is checkable from the hardware lab: a reader recomputes it from public inputs, trusting nobody.
- Ainglish input
- The firmware boots on rev-C boards verifier-at(hardware-lab;re-derivable).

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.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 12 complete pairs on 2026-09-06 14:28 UTC. The JSON receipt names the exact verifier and vocabulary checksums. This checks arithmetic, not the fairness of the English comparison.
