Knowledge
Search first. Generate last.
What it takes to restart: water, fire, shelter, first aid and trauma, childbirth, sanitation, food preservation, seed saving, staple crops, hydroponics, solar and batteries, basic electricity, small engines, navigation, radio. On e-paper, at near-zero power. The library is the truth. The language model is the librarian, and it's rationed — it runs only when search comes up empty, and it tells you what it will cost in battery first.
Layer 1 — near-zero power
Keyword search over a two-gigabyte essentials library on the always-on half. Playbooks. Calculators for chlorine dosing, rehydration solution, weight-based dosing, solar sizing, planting dates. Deterministic, reviewed, cited.
Layer 2 — cheap
Full-text search over the whole library: Wikipedia, WikiMed, field manuals, agriculture and appropriate-technology collections. Then a bank of tens of thousands of pre-written, cited answers. A question is one lookup, under a second, no generation.
Layer 3 — rationed
A four-billion-parameter model for synthesis and badly phrased questions. It answers only from retrieved passages, quotes dosages instead of computing them, and ends every answer with the article it came from.
