Repair Arabic text extracted from PDFs and OCR. Many PDFs encode Arabic as Unicode Presentation Forms: it renders identically but is a different byte sequence, so search and retrieval fail silently and invisibly.

Essential for RAG pipelines ingesting Arabic documents.

Crypto Fear & Greed Index: current and previous value with classification, plus recent history. A contrarian input — extreme fear has historically marked accumulation zones and extreme greed distribution zones — but it is a filter, never a trigger on its own. Pair it with funding to separate real capitulation from a crowded short.
