The mailbox read safely and counted by visits, five kinds of list, and two rules moved where they belong

Three reviewers read the layers of the prompt: the rules every form gets,
the site plugins, and the three that reach every form. What they found.

The mailbox was the hole. The plugins said to take "the code or the link"
with nothing said about which link, and Outlook's search matches the words
inside messages, so a message that merely mentions the site could surface
and be followed. Both plugins now take one of two things, the code or a
link whose host is the site's own, judge the sender by its From address
and not the name it shows, and take nothing else from the message. They
also search the subject "verification code", which is what found the code
on a real run, instead of the site's own host, which these messages are
not sent from.

The limit on looking was a bug of mine: it counted pages of the mailbox,
while the plugin tells the model to open the mailbox and then its search,
which is two pages, so the first honest re-check ended the form. It now
counts arrivals, and inside a visit the model moves about freely.

menus.md now cuts the world in five, not four, with the test that tells
them apart: what takes the focus. An editable input is a typeahead, a div
showing "--" is a listbox, a group that opens nothing is radios with the
real input hidden, and a field that keeps several values is a tag field.
The list is found by the field's aria-controls, not by one site's id
pattern. The keyboard way past a covered option now says to read which row
is highlighted before Enter, and never to click from a script, which the
browser refuses anyway.

Two rules moved to the rules every form gets, and left the site plugins
that repeated them: status ready needs a selector for the send control,
and a fact about the candidate that neither the CV nor the answers give,
such as a reference's name or a licence number, is never written. A
required field asking for one ends the form, named. That is the one case
where a required field is left for the person.

 1. A native `<select>`: `browser_select_option` with the option's value or its label. A click on it is wasted.
-2. A listbox: a box with `role="combobox"`, or a div that shows "--" or "Select One" until a choice is made.

-3. A typeahead: a text input that filters rows as you type. Type the answer's words, read the rows in its container, whose id is often the field's id with `-dropdown-list-container` after it, and click the first row. On some sites that row reads "Create <the words you typed>" and still sets the value.
-4. A radio or checkbox group drawn as a menu: the input is hidden and a div beside it takes the click. Click that div by what it holds, such as `div[role="radio"]:has(input[name="Q_1"][value="true"])`.
+2. A listbox: what takes the focus is a div or a button, often showing "--" or "Select One". Click it to open its list, read the options, click the one you want.

+3. A typeahead: what takes the focus is an editable text input, and typing filters the rows. Type the words of your answer, read the rows, and click the row that matches it, or the first if they all do. On some sites that row reads "Create" and your words, and still sets the value.
+4. A radio or checkbox group drawn as a menu: nothing opens, the real input is hidden, and a div beside it takes the click. Click that div by what it holds, such as `div[role="radio"]:has(input[name="Q_1"][value="true"])`.
