Bunker Bot & Retrieval
  • ImproveRetrieval understands intent, not just words — survival-domain query expansion plus domain routing (trauma / obstetric / dental / water / navigation / radio), so "stop heavy bleeding" now cites the trauma manuals, not the childbirth chapter
  • NewTerminal Bunker Bot (bunkerbot.py) — the whole assistant in one zero-dependency Python file: same retrieval, same citations, works over SSH and on a Pi; falls back to a citing search tool with no model running
  • NewBunker Bot Compendium — a 29th bundled book: master index & quick-reference tables, fully indexed for citations
Content
  • NewSalvage, Rebuild & Fuel — 28th section: parts salvage & safe stripping, generator maintenance/rebuild, car-alternator generators, battery salvage (lead-acid + 18650), biodiesel, SVO, ethanol and wood gas
  • NewFour more bundled books (33 total): TM 5-685 Auxiliary Generators, FEMA Wood Gas Generator plans, NREL Biodiesel Guide, Fuel from Farms (ethanol)
  • NewPractical build sections: Power Systems, Structures, Water Systems, and Medicine-Making
  • NewMedical: choking (adult/child/infant), spinal injury & moving a casualty · Climate: predicting weather without instruments · Energy: charging devices, salvaging solar panels, repairing electronics
  • NewAbout page — the project's ethos, honest limitations, and how to help
Site, App & Cinematics
  • NewPublic landing page at bunkerbot.co.uk with an animated three-act hero (storm → meteorite → the horde — the bunker light always comes back on)
  • NewInteractive photo-real night-Earth globe on the Maps page (NASA city-lights imagery, drag to spin) with a "last light" cinematic
  • ImproveFull PWA: install prompt, offline fallback page, iOS support; animated scenes across Download, AI-setup, Maps, Expansion and Disasters pages
Distribution & Integrity
  • Newmake-usb.sh — one command copies the guide to a USB stick and re-reads every byte against SHA-256 hashes
  • Newpi-setup.sh — one line turns a Raspberry Pi into a survival AI server: guide + Ollama + a RAM-sized model, serving your network on boot
  • Improveget-knowledge.sh rebuilt as a one-button ZIM downloader — sh get-knowledge.sh wikipedia-maxi resolves the current file, checkpoints and resumes across crashes/reboots on multi-day downloads, and verifies the finished file against Kiwix's published SHA-256; new get-library.sh fetches a whole curated bundle (or the entire catalogue) in one run and builds a combined kiwix-serve index
  • NewFour small on-theme Expansion Library archives: a dedicated post-disaster guide, low-resource medicine, water/sanitation, and knots — each under 1 GB
  • NewOne-command setup per OS — mac-setup.sh, windows-setup.ps1, and an upgraded pi-setup.sh install Ollama, detect your real RAM/CPU/GPU, pick a model, pull it, and prove it answers, with no need to read the hardware table first; direct download buttons on the AI Setup page
  • ImproveModel selection now scales down to genuinely old/low-resource hardware (smollm2:135m fits ~450MB RAM; 32-bit and unsupported-OS systems get a clear explanation and fall back to Bunker Bot's search-only mode instead of a confusing failure)
  • FixDownload packages now ship a manifest matching their contents, so verify.sh passes in an extracted download
Next Under consideration Planned
Under Consideration
  • ImproveClinician review of the medical sections — volunteer here
  • NewBundle King's American Dispensatory (PD herbal) and a compact Gray's Anatomy
  • NewPrintable section posters — key diagrams sized for A3/tabloid printing
  • ImproveMore pre-built map regions and an on-page region search
  • ImproveBunker Bot: clickable citation chips that open the cited page in the PDF library
v1.0 June 2026 — Initial public release Superseded

The launch build: the complete offline library, an AI that cites its sources, offline maps, and full distribution tooling — live at bunkerbot.co.uk and free to download.
