Steganographic Channels: A History and Formalization of Encoding in Plain Sight, version 1.1, is a theoretical paper by Lee Sharks and the Operator Assembly, deposited 29 September 2026 as the second version of deposit #616 (March 2026). It defines a steganographic channel as a public medium that carries a payload legible only to readers holding a key, and models every channel through five components: carrier, payload, key, noise and filter. It surveys African American spirituals, Sufi and troubadour poetry, alchemical texts, blues, hip-hop, samizdat, Polari and early-modern scientific writing as proposed historical instances, then describes the Crimson Hexagonal Archive as a temporal steganograph addressed to future machine readers, with the blog, the DOI network and the CC BY 4.0 license as carriers and filters. Its case study documents the OCTANG-001 provenance adjudication of a platform that reproduced the archive's Rosary Embassy architecture without attribution. Version 1.1 withdraws, as disproportionate, v1.0's analogy between that implementer and the slaveholders of the spirituals section, removes his town, and renders one LaTeX example in plain words; the rest of the text is unchanged, and v1.0 remains on the record.
