What the source labels mean
Astronomical documentation supports coordinates and algorithms. Historical texts, museums and scholarship document practices and their development. Dictionaries and naming sources document word origins, translations and authored terminology. Original practitioner sources establish what a system's teachers claim or prescribe. They do not independently establish predictive, biological or spiritual claims.
The wiki is a sourced study edition. Some articles are gateways into broad or disputed families; their limits are stated on the page. Numerical engine coverage is recorded separately from interpretation coverage.
