# `Perplexed.Verdict`
[🔗](https://github.com/agoodway/perplexed/blob/v0.2.0/lib/perplexed/verdict.ex#L1)

Judges whether fetched page text is worth handing to a model.

An HTTP 200 alone is not success. A bot challenge, a JavaScript shell that
renders nothing without a browser, or a page with almost no readable text
all come back as 200s. The fetch ladder uses the verdict to decide which
tier to try next: a challenge is worth an impersonated retry, while a
JavaScript shell needs a real browser.

Markup markers that only a challenge page carries (such as `cf-chl-` and
`challenge-platform`) count on any page of at most 4,000 characters.
Phrases a real page could also contain ("captcha", "access denied") count
only on a page of at most 1,000 characters, so an article that mentions a
captcha is not mistaken for a challenge. A page of at most 1,500 characters that
says it is behind a sign-in or subscription ("sign in to continue",
"subscribe to continue reading"), or a near-empty page holding a
password field, is a `:login_wall`; a prompt to sign in to comment is not.
Like a JavaScript shell, a login wall skips the impersonated rung: a
browser fingerprint does not sign in.

# `t`

```elixir
@type t() :: :ok | :challenge | :login_wall | :js_shell | :thin
```

# `judge`

```elixir
@spec judge(String.t(), String.t() | nil) :: t()
```

The verdict for a page's readable `text`, using `raw` (the undecoded HTML,
when there was any) to tell a challenge or JavaScript shell from a page
that is merely short.
