Ruled out failed its test

The glyph stream has been transposed with a fixed period (columnar, route or decimation), as the Zodiac-340 cipher was.

Kind: hypothesis
Stage: tested
Tests: ["T11-periodicity"]
Family: CIPHER
Origin: deductive
Result: Period-bigram counts are flat: the best period (p = 2) exceeds the median over p = 2..60 by 0.04 %, in the text and in every surrogate alike. kappa(p) peaks at p = 6, the mean word length plus space, in the text and in all surrogates that keep the words.
Predictions: ["the count of repeated bigrams when the stream is read at period p peaks sharply at the true period", "and the periodic coincidence kappa(p) shows a peak absent from the within-word shuffle"]
Ledger status: not-supported
