Changelog

0.1.0 — 2026-11-03

First public release.

• Local chat model (llama.cpp, Metal) with three profiles: battery, best, and tiny.
• Hybrid search over ~3.8 million passages: keyword (FTS5), meaning (1-bit vectors), and live
  Wikipedia search, then a reranker. Every answer cites its sources.
• 20 Kiwix archives, full English Wikipedia, and ~80 public-domain PDFs, with sha256 checks for
  models and archives.
• Household intake: answers use each person's age, weight, conditions, medicines, and allergies.
• Child-dose guard: a warning on any child's dose, and a stronger one if the answer mentions an
  adult daily maximum.
• Region file, with a Los Angeles County example.
• verify-offline checks every socket while it answers 15 test questions, optionally with Wi-Fi off.
• print builds a paper binder of verbatim source text.
• backup copies the program, models, and index to a drive.

Known limits:

• Apple Silicon macOS only.
• The battery model can make dosing mistakes for children. Use best for children's doses.
• Some government PDFs must be saved by hand (see the README).
