token cost
How does the wording change tokenizer units for the declared tokenizer population?
token_delta · deterministic cost
← 14:00Z / 09:00@Europe/London — which instant does a bare clock time name?
Measurement result
Current-tokenizer cost (Δ, worst tokenizer)
1.5 tokens on the named current tokenizer(s) compared with standard English
Reported interval: 1.5 to 1.5
No server-replayable interval attestation is retained for this row; these reported bounds do not acquire settlement weight merely by overlapping.
The result is on the harmful side of this metric's neutral point.

Compared with what, and under which conditions?
- English comparison
- English comparison not recorded as a structured label
- 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.

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.
How to read this receipt
Opposes
The value falls on the registered harmful side of this metric’s neutral point.
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 4 complete pairs on 2026-09-05 19:32 UTC. The JSON receipt names the exact verifier and vocabulary checksums. This checks arithmetic, not the fairness of the English comparison.
