How does the wording change tokenizer units for the declared tokenizer population? - Reported result
- -30.766666666667 tokens per declared item
Reported interval: -31.333333333333 to -30.766666666667.Fewer tokens on the named current tokenizers; this is the encoded-length difference, not the proposal decision.
- English comparison
- English comparison not recorded as a structured label
Declared by the submitter; not a certification of equivalent information.
- Tokenizer conditions
- Literal encoding cost on the named current tokenizers; not comprehension.

- Conditions covered
- Separate outcomes retained for all 3 declared conditions
by-construction,by-rule,in-practiceAn overall average can hide a weak condition. A condition list is not proof that every form or claim in the proposal was tested.
- Settlement role
- Awaiting independent settlement
An original reports one result. It does not confirm itself.
- 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?
- Awaiting independent settlement.
An original reports one result. It does not confirm itself.
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.
Does the overall result hide differences between conditions?
| Condition | Reported difference | Reported interval |
|---|---|---|
by-construction | -42 | Not recorded |
by-rule | -27.4 | Not recorded |
in-practice | -22.9 | Not recorded |
A missing condition interval is not zero uncertainty. An overall interval cannot substitute for agreement in every load-bearing condition.
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 30 readable, inline study items, in stored order—not a selection of successes. 0 control items are kept separate.
Each result has its own input pages. Positions across the two studies do not imply matched cases.
Input 1 · barcode-width
- English input
- Labels emitted by Printer Aspen contain twelve digits because of how the system is built: its unchanged encoder allocates exactly twelve digit positions. While it remains unchanged, an exception cannot occur; a label with any other digit count would falsify this claim or prove the system changed.
- Ainglish input
- Labels emitted by Printer Aspen contain twelve digits by-construction.
- Condition
- by-construction
Input 2 · binary-switch
- English input
- Switch Birch reports either zero or one because of how the system is built: its unchanged state representation has only those two values. While it remains unchanged, an exception cannot occur; any third reported value would falsify this claim or prove the system changed.
- Ainglish input
- Switch Birch reports either zero or one by-construction.
- Condition
- by-construction
Input 3 · sealed-vessel
- English input
- Vessel Cinder has no open gas path because of how the system is built: its unchanged shell and fittings form a closed boundary. While it remains unchanged, an exception cannot occur; a continuously open path through the boundary would falsify this claim or prove the system changed.
- Ainglish input
- Vessel Cinder has no open gas path by-construction.
- Condition
- by-construction
Input 4 · sorted-ledger
- English input
- Ledger Dogwood stores entries in timestamp order because of how the system is built: its unchanged insertion routine places each entry by timestamp. While it remains unchanged, an exception cannot occur; an entry stored out of timestamp order would falsify this claim or prove the system changed.
- Ainglish input
- Ledger Dogwood stores entries in timestamp order by-construction.
- Condition
- by-construction
Input 5 · even-frame
- English input
- Frames emitted by Encoder Ember have even pixel widths because of how the system is built: its unchanged frame type admits only pairs of horizontal pixels. While it remains unchanged, an exception cannot occur; an emitted frame with an odd width would falsify this claim or prove the system changed.
- Ainglish input
- Frames emitted by Encoder Ember have even pixel widths by-construction.
- Condition
- by-construction
Input 6 · three-channel
- English input
- Images from Camera Fir contain three colour channels because of how the system is built: its unchanged pixel layout allocates exactly three channels. While it remains unchanged, an exception cannot occur; an image carrying another channel count would falsify this claim or prove the system changed.
- Ainglish input
- Images from Camera Fir contain three colour channels by-construction.
- Condition
- by-construction

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.
Declared population, method and retained outcomes
- Compared with
- registered regime marker versus its complete English meaning, including what an exception would establish and who would owe
- Tested population
- 30 frozen complete standing-property claims, 10 per regime across 30 distinct new domains
- Unit tested
- one complete standing-property claim with exception semantics
- How results combine
- equal-pair mean per tokenizer over all 30 claims, then the least-favourable maximum tokenizer mean; retain all three equal-weight regimes separately
These are the study author’s declarations. A finding applies to this tested scope; this summary does not establish that another study is comparable.
Absolute arm results, reader-specific results and condition results below are retained values, not a newly pooled analysis. Accuracy arms use fractions from 0 to 1; their difference uses percentage points.
