AsepSys

Asepsis Protocol Optimizer — a single-file, fully offline tool that turns sterility math and aseptic technique into one adaptive engine. It sizes the minimum-sufficient kill dose for a specific item, recommends the gentlest method that still meets the goal, builds the cheapest independent barrier stack that hits your risk target, and closes the loop with a timestamped verification log.

No build step. No dependencies. No network. One .html file you open in any browser — nothing leaves your machine.

What it does

• Minimum-sufficient dose. Computes the exact kill required for your item (required reductions = log₁₀(N₀) + 6 for a 10⁻⁶ sterility floor) instead of a one-size-fits-all cycle, so you never over-treat.
• Most-selective method. Among the methods you actually have, it recommends the one with the least material impact that still clears the goal — the selectivity principle, so you damage the item as little as possible.
• Barrier-stack optimizer. Treats aseptic technique as independent barriers (P(contamination) = ∏ pᵢ) and adds them cheapest-effective-first, stopping once your risk target is met and telling you which barriers are not worth their cost.
• Verification log. Generates an item-specific run sheet, timestamps each step as you complete it, forces an indicator-verification step, and exports the cycle as .txt or .json for an audit trail.

Quick start

1. Download asepsys.html.
2. Double-click to open it in any modern browser.

That's the whole install.

How it works

Three pieces of established science, unified into one engine:

• First-order death kinetics — N(t) = N₀ · 10^(−t/D)
• Sterility Assurance Level floor — survivors driven to 10⁻⁶
• Independent barriers — P(contamination) = ∏ pᵢ

Configure it

Open the <script> block and edit two arrays:

• METHODS — each method's D-value (or dose-per-log / filter LRV), sporicidal flag, material-impact rating, and cost.
• BARRIERS — each barrier's breach probability p and friction cost.

Replace the illustrative defaults with values from your own validated chemical or biological indicators. Rename the app on the line marked id="appName".

⚠️ Scope and safety

This tool is for objects, surfaces, and lab/hobby/household contexts. It is not a substitute for validated, regulated sterilization of anything that enters the body — surgical, implant, or injectable use requires certified equipment and formal validation.

The built-in parameters are illustrative reference values. The math sizes a dose; a physical indicator is what proves the cycle worked, which is why the tool refuses to skip that step. Method hazards: pressure cookers (steam and pressure burns), UV-C (eye/skin damage in seconds — never expose people), bleach (corrosive; never mix with ammonia or acids).
