Build and maintain a Karpathy-style LLM Wiki - a persistent, interlinked markdown knowledge base that sits between you and your raw sources. Faithful to Andrej Karpathy's LLM Wiki pattern (gist 442a6bf5). Three layers (immutable sources / LLM-written wiki / schema) and three operations (Ingest, Query, Lint). Use for research deep-dives, book/paper companions, competitive analysis, or any domain where knowledge should compound over time instead of being rediscovered each session. NOT a task manager - for weekly tasks/PRDs/org use /arise instead.
