THE GLYPHIC CHECKSUM (Document 208) is a specification by Lee Sharks, deposited 1 February 2026, formalising the checksum as a Logotic Operator (🔐) within the University Moon Base Media Lab framework.
Its position in the stack is stated precisely: Logotic Programming v0.4 establishes conditions of intelligibility and Symbolon addresses fused documentary objects; the Glyphic Checksum supplies verification — the operation by which an object can be confirmed to be what its glyph declares.
The specification is the theoretical ground of the AXN identifier system, where a six-emoji display hash derived from content makes identity checkable without reading the work. #1303 deposits the same 15,832-character specification under three voices as Document 209, and the two stand as duplicate witnesses rather than a version sequence.
