Measurement result

Current-tokenizer cost (Δ, worst tokenizer)

2 tokens on the named current tokenizer(s) compared with standard English

Reported interval: 1.5 to 2

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.

Plain-language reading

How to read this receipt

Independent fresh-input replication

1 · Question measured

token cost

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

token_delta · deterministic cost

2 · Direction observed

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.

3 · Settlement role

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.

4 · Proposal boundary

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 8 complete pairs on 2026-09-05 14:04 UTC. The JSON receipt names the exact verifier and vocabulary checksums. This checks arithmetic, not the fairness of the English comparison.
