The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

performing homoglyph substitution--the replacement of characters with visually similar alternatives (e.g., 'h' [U+0068] → 'h' [U+04BB])--on text can degrade stylometric systems.

C2weakest assumption

That stylometric systems primarily rely on character-level or Unicode-sensitive features that homoglyph substitution will reliably disrupt without introducing new detectable patterns or being normalized by preprocessing.

C3one line summary

Homoglyph substitution on text degrades stylometric systems to hide author signatures and personal information.
