Device info is the page you open to read your radio out to somebody, the one that
gets screenshotted into a forum thread and left up while a colleague leans over
your shoulder. Every value on it is yours to give away except one: the BLE
pairing PIN is what lets another phone onto the radio, and it was sitting in the
Identity section in plain digits alongside the node name and the coordinates.
It now draws as the field rather than the value — six mask bullets, the same
glyph a password prompt types in, promoted to marks.MASK_MARK so the two can
never drift apart. Six is the width of the *field* (the setting's own bound is
999999), not of what is in it: masking per character is right while someone is
typing and counting their own digits, and wrong for a stored secret, where it
would say how many to guess. A device that reports no PIN keeps its "?" — an
absence is not a secret, and a "?" behind bullets would promise something to
uncover.
`p` uncovers it, and `p` puts it back. A bare letter is a read-only page's idiom
for its own verb (the Time Machine's `w`) and this page has no find-as-you-type
to compete for it; the footer names what the press would do *now* — `p show PIN`,
then `p hide PIN` — and on the console the same toggle is F3, `Reveal` then
`Hide`, since the lane is the only place that platform can learn the key exists.
A device with no PIN advertises neither: the atom drops and the slot stays empty,
because the action isn't a thing on that page at all.
The page is therefore its own screen now (ui/device_info_screen.py) rather than a
generic result window, and ScrollScreen grows `replace_content` — replace_items
for a read-only body — so the toggle swaps the page under a reader who keeps
their scroll position; nothing reflows, six cells become six. The CLI has no key
to press, so `meshterm info` and `config show` print it masked and
`config get device_pin` is the way to name it deliberately: one rule, which is
that the whole-device dump never carries the PIN. The editor one menu over still
lists it plainly — you go there to change it, a row at a time, and its letters
already belong to find-as-you-type.
