# The post-dive debrief

import { ReviewStep } from "@/components/react/PostDiveScreens";

The debrief narrates one completed dive against the plan it was meant to follow.
It is written on request at the end of a post-dive review, from the button
**Debrief this dive with AI**: one answer, no follow-up, nothing kept. It
calculates nothing. Everything it says comes from the review you just completed.

## What it is given

- **The plan**: name, open or closed circuit, planned maximum depth and runtime.
- **Plan against actual**: adherence score out of 100, maximum depth, time to
  reach depth, mean depth deviation, time spent on the planned depth, runtime
  and peak ascent rate.
- **Stops**: every stop, planned and actual minutes side by side.
- **Differences**: each one found, with how serious it is.
- **Your own answers**: decompression-stress band and score, and the top three
  contributing factors.
- **Symptoms**: any symptom you reported, with how long after surfacing it
  began.

The band, the score and the contributors are the review's own reading of your
answers, worked out before Tunang is asked anything. Nothing else about you
reaches it: no dive history beyond this dive, no other reviews, no account
detail.

## How it reads

Plain prose in short paragraphs, no headings, no list longer than three items,
facts with their numbers ("you reached 40 m about 2 minutes after the plan
expected"), and under roughly 250 words: what happened against the plan, what
most likely caused each difference, and two or three adjustments for next time.

## Its limits

**It is not a medical device.** It is forbidden from diagnosing decompression
sickness or ruling it out. Neither a clean adherence score nor a low stress band
may be described as making DCS impossible, because neither does.

**A reported symptom changes the first sentence.** If you reported any symptom,
the debrief opens by acknowledging it and directing you to the guidance the app
gives: breathe 100 % oxygen if available, and contact DAN (+1-919-684-9111) or a
dive physician, even if the symptom seems mild or is fading.

**It reads the evidence, it does not add to it.** Where more than one
explanation fits, it must say so and take the conservative reading. It is
forbidden from inventing anything it was not given.

**It is one opinion about one dive.** It is not a clearance to repeat the
profile, and where it matters the next conversation is with your instructor or a
dive physician.

- [Plan adherence](/post-dive/adherence) is the comparison it narrates.
