test: tighten two checks in the persisted-field harness (closes #379)

The polarity check now counts only `hostile` and `falsy` values, not a
`hostileRestore` value, which reaches only the views its entry names.
The stale index 5 moves into `hostile` for `selectedWallet` and
`selectedAddress`, as each field's one value still truthy after the
floor.

Each `hostileRestore` entry declares whether its boot lands on its view
or falls back to Home, and the test checks the one view on screen. A
value driven onto every restorable view lists only the views it falls
back on, so a view added later is driven by default.

The header and the README restate the remaining limits as built and say
which boots are held to where the popup lands.

 # Completed Steps
 
+- 2026-10-07: Two holes in what `tests/persistedFieldContract.test.js` checks
+  are closed ([#379](https://git.eeqj.de/sneak/AutistMask/issues/379)). The
+  check that every swept field is driven both truthy and falsy counts only
+  `hostile` and `falsy` values, which the sweep drives onto every restorable
+  view, and no longer a `hostileRestore` value, which reaches only the views its
+  entry names; the stale index 5 moves into `hostile` for `selectedWallet` and
+  `selectedAddress`, as the one value of either still truthy after the floor.
+  Each `hostileRestore` entry declares whether its boot lands on its view or
+  falls back to Home, and is held to it. The limits that remain, fields that
+  share a slot on one boot and anything no stored record reaches by itself, are
+  restated as built in the file's header and the README, which now also say
+  which boots are held to where the popup lands and that a healthy profile is
+  booted onto every restorable view.

 - 2026-10-07: Every password error in the popup is shown the same way
   ([#493](https://git.eeqj.de/sneak/AutistMask/issues/493)): with `showError()`
   and `hideError()` in a fixed-height error line below the password field, as
