# Step 1 — Simple Total Latency

## What this step delivers

`latprobe` accepts one or more URLs and prints the total wall-clock time of
each HTTP GET request (including body download). No per-phase breakdown yet —
that comes in Step 2.

## Build

```sh
cd go
go build -o latprobe .
```

## Usage

```sh
latprobe <url> [url ...]
```

## Examples

Single URL:

```sh
$ ./latprobe https://example.com
https://example.com                            200  70ms
```

Multiple URLs:

```sh
$ ./latprobe https://example.com https://www.google.com
https://example.com                            200  70ms
https://www.google.com                         200  127ms
```

Error (unreachable host):

```sh
$ ./latprobe https://doesnotexist.invalid
error https://doesnotexist.invalid: Get "https://doesnotexist.invalid": ...
# exits with code 1
```

## Output columns

| Column | Description |
|--------|-------------|
| URL | The requested URL |
| Status | HTTP response status code |
| Total | Wall-clock time from request start to body fully received |

## Flags accepted (not yet functional)

`-n`/`--count` and `--json` are parsed but produce no effect until Steps 3–4.
