feat: remove an address from an HD wallet, behind a confirmation (closes #162)
All checks were successful
check / check (push) Successful in 25s
Details

Browse Source 
Address rows on Home now carry an [x] control on wallets that derive their
addresses from an extended key and hold more than one; it opens a confirmation
screen before anything is removed.

Removing an address destroys nothing: it stays derivable from key material the
wallet still holds, and any funds at it stay where they are. That is also why
the screen is not password-gated, unlike delete-wallet — a password gates the
disclosure or destruction of a secret, and this does neither.

Getting the address back into the list is another matter, and the copy states
it exactly rather than promising a route the app refuses. "+" derives the next
unused index, because the derivation counter is a high-water mark and is not
rewound, and re-importing the wallet's key material is rejected as a duplicate
for as long as the wallet is present — which it always is here, since a wallet
never gives up its last address. What works is deleting the whole wallet in
Settings, which asks for the password and destroys the stored secret, then
importing again: the scan that follows rediscovers the address only if it has
on-chain activity, and an address that was never used does not come back at
all. The text is built by recoveryPathText() rather than sitting in index.html
so it can name the wallet's own kind of key material, an xprv wallet having no
recovery phrase to re-import.

A balance is surfaced as a warning, never a refusal, and holding something
means any ERC-20 as well as ETH, at any size: an address with no ETH and a
stablecoin position must not get a blank line on the screen whose job is to
warn. The warning names no figure of its own, because the balance lines round
to four decimals and a sentence built from a rounded number would report
0.0000 ETH for an address holding real money; the amounts come from the same
balanceLinesForAddress() and getAddressValueUsd() every other screen uses.

The state transition lives next to the wallet one in
src/shared/walletDelete.js and shares its address comparison, site-permission
cleanup and broadcast, so the rules match one level down: the last address of
a wallet is never removable, the selection moves only when it was the address
removed, an index after the splice is decremented, a selection in another
wallet is untouched, and AUTISTMASK_ACTIVE_CHANGED is broadcast when the
active address moves so a connected site stops being told about an address the
user removed.

#### DeleteAddress (`delete-address-confirm`)
- **When**: User tapped the `[x]` next to an address on Home. Offered only on HD
and xprv wallets holding more than one address: the last address of a wallet
is never removable, and a key wallet has exactly one.
- **Elements**:
- "Back" button, "Remove Address" heading
- The address's own label ("Address N") and its wallet's name
- The full address (color dot, etherscan link, tap to copy), with the ENS
name above it if resolved
- Explanation that this only stops the wallet tracking the address: nothing
is destroyed, no key is deleted, and funds stay where they are
- The route back, stated with its limit, because the obvious two are both
refused: "+" derives the next unused index (`nextIndex` is a high-water
mark), and re-importing the wallet's key material is rejected as a
duplicate by `findWalletByXpub` while the wallet is still present. What
works is deleting the whole wallet in Settings — password-gated, and it
destroys the stored secret — then importing again, whereupon
`scanForAddresses()` rediscovers the address **only if it has on-chain
activity**. An address that was never used does not come back. The text is
written by `recoveryPathText()` rather than sitting in `index.html`, so it
can name the wallet's own kind of key material: an xprv wallet has no
recovery phrase to re-import.
- A warning when the address holds anything, ETH or any tracked ERC-20,
followed by the holdings themselves via `balanceLinesForAddress()` and the
USD total via `getAddressValueUsd()`. The sentence names no figure of its
own: the lines round to four decimals, so a sentence built from a rounded
number would report `0.0000 ETH` for an address holding real money. The
predicate is `addressHoldsFunds()` in `src/popup/views/helpers.js`,
unrounded and token-aware. A balance is a warning, never a refusal.
- The rule that a wallet always keeps at least one address, and that
removing the last one means deleting the wallet from Settings
- Error line
- "Remove Address" button
- **Transitions**:
- "Remove Address" → removes the address and its site permissions, then →
previous screen (Home) with an "Address removed." flash message
- "Back" → previous screen (Home), nothing removed
- **Deliberately not password-gated**, unlike DeleteWallet: a password gates the
disclosure or destruction of a secret, and this does neither. The address
stays derivable from key material the wallet still holds.
- The active address moves only if it was the address removed, and then to the
wallet's first remaining address, with `AUTISTMASK_ACTIVE_CHANGED` broadcast
so a connected site stops being told about an address the user removed
(`src/shared/walletDelete.js`). A selection in any other wallet is left alone;
one in this wallet follows the splice.
- The wallet's derivation counter (`nextIndex`) is not rewound, so "+" derives a
fresh address rather than handing back the one just removed.
#### SettingsAddToken (`settings-addtoken`)
