Experimental method / v0.1.0
Torsion
Fold
A method for representing where meaning bends during compression, translation, summarization, and agent handoffs.

observed output
Working definition
A fold is the transformation path. Torsion is the change that prevents the path from closing cleanly.
This method compares supplied artifacts. It does not determine whether either artifact is true, intentional, complete, or authoritative.
Seven invariants
What the method watches
The first implementation detects explicit textual signals. Later versions may add structured-data and multilingual adapters without changing the evidence boundary.
02
Quantity
Are numbers, units, currencies, and proportions preserved?
numberspercentagescurrencyunits
03
Time
Are dates, durations, sequence, and deadlines preserved?

04
Modality
Does possibility remain distinct from certainty or obligation?
maymightlikelymustconfirmed
05
Negation
Are exclusions, denials, and exceptions still attached to the right claim?
notneverexceptwithoutunless
06
Authority
Are permission, delegation, and policy boundaries preserved?
maymustalloweddeniedauthorized
07
Provenance
Can the transformed claim still be traced to its stated source?

These cases demonstrate contract behavior. They are not an accuracy claim or representative evaluation corpus.
preserved quantity and timePRESERVED
- Source
- The pipeline processed 240 records on September 18, 2026.
- Transformed
- On September 18, 2026, the pipeline processed 240 records.
Order changes while the actor, quantity, action, and date remain stable.
shifted quantitySHIFTED
- Source
- The service processed 240 records during the test.
- Transformed
- The service processed 420 records during the test.
The claim remains recognizable but its quantity changes.
dropped negated boundaryDROPPED + PRESERVED
- Source
- The scanner does not determine whether a claim is true. It compares two supplied texts.
- Transformed
- The scanner compares two supplied texts.
The operational description survives while the negated truth boundary disappears.

- Source
- The registry may launch after review.
- Transformed
- The registry may launch after review. The launch is guaranteed this month.
The transformed artifact adds a certainty claim absent from the source.
