|---|---|---|---|
| Encyclopedia of Korean Culture | 1509–1571 onward | Baseline source | Biographical references can be checked, while each prophecy needs its own manuscript chain. |
| Scholarly or institutional interpretation | Later review | Context layer | Explains language, history and uncertainty without becoming the original text. |
| Viral quotation or modern event match | Recent circulation | Derivative layer | Most vulnerable to translation drift, omitted failures and hindsight; compare with Encyclopedia of Korean Culture. |

Where interpretation changes
The main dispute concerns the distance between 1509–1571 onward and Historical life · local tradition · late attributed text. Translation, selective quotation, changed definitions and hindsight can make a broad record appear more exact than it was. Competing readings are therefore preserved rather than silently merged.10 · EVIDENCE SCORE & PROVISIONAL CONCLUSION
