Every deposit receives a three-layer identifier combining positional, semantic, and cryptographic identity:
AXN — Alexanarch namespace. 06 — Hex position (WHERE). LIMINAL — Semantic family (WHAT). 🏛️🌀🔧💎 — Emoji hash (WHICH — first 4 bytes of SHA-256).
The emoji hash is computed by mapping each byte of the content's SHA-256 through a table of 256 curated emoji, organized in 16 semantic clusters: Celestial, Elemental, Architectural, Instrumental, Scriptural, Navigational, Temporal, Organic, Symbolic, Mathematical, Alchemical, Gestural, Signal, Structural, Liminal, Terminal.
Change one word and the emoji changes. The hex and family stay stable across versions; the emoji distinguishes them.
The 4-emoji form is the display alias — memorable, citable, visually distinctive. The full SHA-256 hex string is the canonical identifier. Both are stored in every deposit record. The display alias has 2³² (~4 billion) possibilities, sufficient for a growing repository but not collision-proof at scale. The canonical hash has 2²⁵⁶ possibilities — effectively infinite. For citation use the display form. For cryptographic verification use the canonical hash. Both resolve through alexanarch.org.
Anyone can verify an AXN: compute the SHA-256 of the original content, map the first 4 bytes through the published glyph table, and compare. No authority needed. No trust required. The content IS the proof.
Alongside the deterministic AXN, deposits may carry a Glyphic Checksum — a non-deterministic structural signature generated by the depositor's AI, encoding the work's structural arc in emoji. The AXN is the address. The GCS is the handshake. Both are emoji. Neither depends on a platform.
