# Asking Tunang

import { ChatConversation } from "@/components/react/ChatScreens";

Tunang is DiveLogic's diving assistant: a model built for this subject rather
than a general one asked about it, wired into the calculations the planner runs.
Ask in ordinary language; when the answer needs a number, Tunang works it out
rather than recalling it, so the figure you get is the figure the app would give
you.

> **Every answer needs checking**
>
> Tunang can be wrong. It can misread a question or state something plainly that
> is not true. Check every answer against your own training, your tables and your
> agency's standards before it changes what you do in the water. It will not tell
> you a dive is safe, and it authorises nothing.

## Start a chat

1. Open **Tunang** from Home, or the **Chat** section in the navigation rail.

2. Press **New chat**. A chat named `New Chat` appears at the top of the list.

3. Type the question into the field labelled `Ask something… (Enter to send)`
   and press Enter.

4. The chat renames itself from your first message. Chats are stored on your
   account, so the same list appears wherever you sign in.

Deleting a chat is permanent: **Delete** in the chat header, or the × on a row
in the chats panel.

## What a reply carries

A line appears in the thread while a calculation runs (*Analysing gas mix*,
*Planning the dive*), and becomes a card when the answer comes back.

Tunang restates the key numbers in words, so a follow-up has something to refer
back to. Given a value it cannot use, the calculation refuses and names it: no
card is drawn, and nothing is swapped for a default.

A request for a whole dive needs a name, a depth and bottom time, and one gas
with its role. Its card carries an **Open in Planner** button, which loads the
plan and saves it.

## How it answers

- **It prefers named sources**: agency material, manufacturer manuals, DAN,
  NOAA, the US Navy Diving Manual, peer-reviewed diving-medicine literature. It
  never invents a source, a standard or a limit, and where the evidence is weak
  or conflicting it says so.
- **It refuses the word "safe".** "You'll be fine" and "people do it all the
  time" are forbidden. It says "lower risk" or "more conservative" instead.
- **In a chat it sees the conversation, not your dive.** An answer that sounds
  specific to your plan is a general answer using your numbers.
