Towards Data Science

A practical guide to building a personal AI knowledge vault inspired by Andrej Karpathy's 'LLM Wiki' concept. The system uses two folders (Raw for immutable source documents, Wiki for LLM-maintained structured knowledge) plus three control files (_hot.md as a cache, _pending.md as a queue, _log.md as an audit trail). Three automation cadences keep it alive: daily ingestion, weekly compilation, and monthly linting. The approach solves the blank-context problem by compiling knowledge once and keeping it current, making context portable across any AI tool.
