DMT Code Open Dataset v4.1

Machine-readable open dataset from dmtcode.com, an open registry documenting visual phenomena reported during N,N-DMT experiences and the associated 650 nm laser diffraction protocols. The registry records observations as dated, licensed entries and publishes supporting and contradicting evidence in the same place under the same license. Version 4.1 snapshot, exported 2026-08-17. Contents: 194 stance-scored bibliography entries, 266 clinical trial records, 27 community visual symbols, 28 registry glyphs, 20 theory entries, 50 timeline events, plus guides and FAQ records. Single JSON file with field definitions, key policy, and attribution metadata embedded. The phenomenon first described by Danny Goler in August 2020 and detailed in a pilot study published in IPI Letters in 2025 (DOI 10.59973/ipil.158) remains an open question. This dataset exists so the evidence, in either direction, accumulates in an inspectable, citable form. Correction to the v1 (December 2025) description: the earlier text stated "3,000+ visual symbols" and "87% inter-observer consistency". Those figures are not supported by the registry data and are withdrawn. The counts above are the current record. Live source of truth: https://dmtcode.com/data.json License: CC BY 4.0.
