fix: a token symbol read off a contract is never stored cut mid-emoji (closes #458)

lookupTokenInfo() cut the symbol at 12 and the name at 64 UTF-16 units,
so an emoji outside the Basic Multilingual Plane could be cut between its
two halves and the half left over stored and shown as U+FFFD. Both are
now cut on code points, as displaySymbol() does. A symbol already stored
broken is not repaired.

+- **Linting and testing run in Docker, as phases of the `Dockerfile`.** There is
-  repos use a multistage build where linting runs in an independent stage based
+  no separate lint file. `script/lint` and `script/test` each build one phase
-  on the `golangci/golangci-lint` image (pinned by hash). This stage runs
+  and nothing else:
-  `make fmt-check` and `make lint` before the full build begins. The build stage
-  then declares an explicit dependency on the lint stage via
-  `COPY --from=lint /src/go.sum /dev/null`, which forces BuildKit to complete
-  linting before proceeding to compilation and tests. This ensures lint failures
-  surface in seconds rather than minutes, without blocking on dependency
-  download or compilation in the build stage.
 
-    The standard pattern for a Go repo Dockerfile is:
+    ```sh
+    docker build --no-cache --target lint -t "$(script/projectname)-lint" .
+    docker build --no-cache --target test -t "$(script/projectname)-test" .
+    ```
+
+    **A stage that is not the last one in the file is built only when the final
+    stage's chain depends on it, or when `--target` names it.** That is why the
+    two gates are always invoked by name here, and why the final stage carries a
+    `COPY --from=` of a harmless file from each of them: without that edge a
+    plain `docker build .` builds the last stage alone and exits 0 having linted
+    and tested nothing.
+
+    **Every `docker build` in `script/` is tagged**, here and in
+    `script/cibuild` and `script/docker`. An untagged build leaves a dangling
+    image behind on every invocation, on every developer host and every CI
+    runner; a tagged one replaces the previous image.
+
+    Inside a phase the tool is invoked directly — `golangci-lint`, `go test`,
+    `eslint`, `prettier` — never through `make lint` or `script/test`, which are
+    themselves a `docker build` and would recurse into a daemon that does not
+    exist in a build step. Formatting is the exception and stays on the host:
+    `script/fmt` writes the working tree, and `script/fmt-check` is its
+    read-only twin.
+
+    **No lint verdict may come from a host invocation of the linter.** On a
+    shared host golangci-lint reads a result cache keyed on file content rather
+    than location, so a second checkout of the same content is served the first
+    one's findings, and a host-global lock in `$TMPDIR` makes concurrent runs
+    exit non-zero with `parallel golangci-lint is running` — a status a caller
+    cannot tell from real findings. Both have produced wrong verdicts in this
+    org, in both directions. A container has its own cache, its own `TMPDIR` and
+    a digest-pinned binary, so neither is reachable.
+
+- **Any build that runs checks is built with `--no-cache`.** Docker invalidates
+  a `COPY` layer only when the copied content changes, so on an unchanged tree
+  the check `RUN` is served from cache, nothing executes, and the build still
+  exits 0. Every `docker build` in `script/` therefore passes `--no-cache`:
+  `script/lint`, `script/test`, `script/cibuild` and `script/docker` are the
+  four, and there is no fifth — `script/check` runs the two gate phases and
+  `script/fmt-check`, and builds no image of its own. A bare `docker build .` is
+  not evidence that anything ran: a sub-second build reporting success is a
+  cache hit, not a result. Never invalidate by pruning — `docker builder prune`
+  and friends destroy a build cache shared with every other build on the host.
+  When a check is added or changed, prove it works by planting a defect it must
+  catch and watching the run fail on it, then revert the defect. A green run
+  alone shows neither that the check ran nor that it covers what it should.
+
+- **The gate phases are separate stages, and the build stage depends on both.**

+  hash), so lint failures surface in seconds rather than after a full compile,

+      `config` at any depth (`**/.git/config`, `**/.git/modules/**/config`): the
+      repository's own, each submodule's under `.git/modules/`, and that of a
+      submodule keeping its own `.git` directory. `git describe` does not need
+      them, and each can hold a credential: a password in a remote URL, or the
+      token the CI checkout step stores there. A submodule whose name has a
+      `config` segment (`config`, `deploy/config`, `config/lib`) loses its whole
+      git directory to `**/.git/modules/**/config`, and Go's version stamping
+      then fails the build: give it a name without that segment
+      (`git submodule add --name`). The stage that compiles has `git` (the
+      Debian Go image has it; an alpine one needs `apk add --no-cache git`) and
+      takes the version from the `VERSION` build argument when one is given,
+      otherwise from `git describe --tags --always`. That gives the tag on a
+      tagged commit; on a later commit, the tag, the number of commits since it
+      and the short commit (`v1.2.3-4-gabc1234`); and the short commit when no
+      tag is reachable. The stage that compiles also marks its working directory
+      safe for git (`git config --system --add safe.directory /src`): a context
+      sent as a tar stream keeps the sender's file owners, and git refuses a
+      checkout owned by another user, so the version would come out empty.
+      `ARG VERSION` has no default, and the build fails if the context carries

 # Completed Steps
 
+- 2026-10-06: A token symbol or name read off a contract is no longer stored cut
+  between the two halves of an emoji
+  ([#458](https://git.eeqj.de/sneak/AutistMask/issues/458)). `lookupTokenInfo()`
+  cut both by UTF-16 units; it now counts code points, as `displaySymbol()` has
+  since [#329](https://git.eeqj.de/sneak/AutistMask/issues/329).
+  `tests/tokenLookupTruncation.test.js` looks up a token whose symbol and name
+  are made of emoji outside the Basic Multilingual Plane. A symbol already
+  stored broken is not repaired.
+
+- 2026-10-06: Reloading or closing the popup no longer logs a request it cancels
+  as a failure in the transaction lists and ENS name lookups on the address and
+  token screens, the address scan after a wallet is created, the endpoint checks
+  in Settings, the wait screen's receipt check, the Send screen's Max fee
+  estimate, or the token lookup on the two add-token screens
+  ([#475](https://git.eeqj.de/sneak/AutistMask/issues/475)). Each checks the
+  signal the popup aborts on `pagehide`
+  ([#218](https://git.eeqj.de/sneak/AutistMask/issues/218)) before reporting a
+  failure; a real failure is still logged. `scanForAddresses()`,
+  `resolveEnsNames()` and `lookupTokenInfo()` take the signal. The e2e suite
+  reloads the popup on the address screen with Blockscout held, and during the
+  address scan with that scan held; jest tests cover each of these with the
+  popup open and closed. Left out: the transaction detail screen and the
+  confirmation screen (its fee estimate and its recipient checks), because they
+  discard the popup context that carries the signal.
+
+- 2026-10-06: The private key export screen opens again in the same popup
+  session ([#460](https://git.eeqj.de/sneak/AutistMask/issues/460)). `show()`
+  found the address line through the element inside it, which its own rendering
+  replaced, so the second open threw before it navigated. The line now carries
+  the `export-privkey-address` id itself. `tests/exportPrivkey.test.js` opens
+  the screen twice, its DOM stub now takes an element out of the document when
+  its parent's contents are replaced, and the `#253` e2e case no longer reopens
+  the popup before its second open.
+
+- 2026-10-06: The canonical files are re-vendored from `sneak/prompts` at
+  `dd4027b` ([#472](https://git.eeqj.de/sneak/AutistMask/issues/472)). The
+  `Dockerfile` has separate `lint` and `test` phases, and its last stage depends
+  on both before it runs `make build`. `script/lint` and `script/test` each
+  build one phase, uncached. `script/check-censored` runs in the `lint` phase
+  and `script/test-verify-build` in the `test` phase. `script/check` runs the
+  two phases and `script/fmt-check`. `script/cibuild` bootstraps, runs
+  `script/check`, then builds the image uncached. Given no `VERSION` build
+  argument, as in a plain `docker build .`, the image build takes one from
+  `git describe` on the `.git` in the build context, which `.dockerignore` now
+  sends without its `config`. The vendored `check.yml` has no `timeout-minutes`,
+  so the `check` job's cap is gone.
+
+- 2026-10-06: Reloading or closing the popup mid-refresh no longer logs the
+  requests that cancels as failures
+  ([#218](https://git.eeqj.de/sneak/AutistMask/issues/218)). Chrome cancels a
+  closing page's open requests just after `pagehide`, and in the page a
+  cancelled `fetch()` fails with the same "Failed to fetch" as a server that
+  cannot be reached, so the home screen's transaction list and the balance
+  refresh logged an error for each, and the e2e suite failed on them. The popup
+  now aborts an `AbortController` on `pagehide`, and those two check its signal
+  before reporting a failure. New e2e tests reload the popup with Blockscout
+  held and require nothing logged, and fail the transaction list for real and
+  require the failure reported; `tests/balanceRefreshCancelled.test.js` covers
+  the balance refresh. The address and token screens and the address scan after
+  a new wallet still log a cancelled request
+  ([#475](https://git.eeqj.de/sneak/AutistMask/issues/475)).
+
+- 2026-10-05: `make build` no longer prints the Node `DEP0205`
+  `module.register()` deprecation warning
+  ([#355](https://git.eeqj.de/sneak/AutistMask/issues/355)). The call came from
+  `@tailwindcss/node`, which the Tailwind CLI loads; `tailwindcss` and
+  `@tailwindcss/cli` are now pinned at 4.3.1, the first release that uses
+  `module.registerHooks()` where Node has it. The compiled CSS computes to the
+  same values; it drops the unused `.start` and `.end` rules and writes
+  `calc(var(--spacing) * 1)` as `var(--spacing)` and `calc(var(--spacing) * 0)`
+  as `0`.
+
+- 2026-10-05: `make dev` watches
+  ([#332](https://git.eeqj.de/sneak/AutistMask/issues/332)). It used to pass
+  `--watch` to a `build.js` that read no arguments, so it built once and exited.
+  `build.js --watch` now builds, then builds again after every change to a file
+  under `src/`, `manifest/` or `icons/`; any other argument fails. It watches
+  each directory rather than using Node's recursive watch, which on Linux stops
+  seeing a file an editor saves by renaming a new copy over it. It writes no
+  build receipt, so nothing can verify what it builds; `make build` remains the
+  way to produce a `dist/` to hand on. `tests/buildWatch.test.js` covers the
+  watch loop against a temp directory.
+
+- 2026-10-05: Every CI job has a `timeout-minutes` cap
+  ([#294](https://git.eeqj.de/sneak/AutistMask/issues/294)): `check` 10 minutes,
+  `e2e-firefox` 15 and `e2e-chrome` 20, each over two and a half times the job's
+  slowest cold-cache run. A hung build or browser now ends its job instead of
+  holding the shared runner for hours.
+
+- 2026-10-05: `PROXY_METHODS` in `src/background/index.js` no longer lists
+  `eth_chainId` and `net_version`
+  ([#326](https://git.eeqj.de/sneak/AutistMask/issues/326)). `handleRpc` answers
+  both itself before its proxy branch, so the list named two methods that are
+  never sent to the RPC endpoint. No other entry is answered earlier.
+  `tests/proxyMethods.test.js` sends every listed method from a page and fails
+  on any that does not reach the RPC endpoint.
+
+- 2026-10-05: The popup's Content Security Policy no longer allows inline style
+  ([#328](https://git.eeqj.de/sneak/AutistMask/issues/328)): `style-src` is
+  `'self'` in both manifests, pinned in `tests/manifest.test.js`. The 42
+  `style="..."` attributes in `src/popup/index.html` and in the markup the view
+  helpers build are now Tailwind classes, each computing to the value it
+  replaced. The 16 address dot colours are written out as whole classes, because
+  Tailwind builds only the classes it finds in the source. The Settings debug
+  well is shown and hidden with the `hidden` class, since clearing an inline
+  `display` no longer uncovers it. Script that sets `element.style` is
+  unaffected.
+
+- 2026-10-05: `.prettierignore` no longer lists an AI vendor's tool directory
+  ([#363](https://git.eeqj.de/sneak/AutistMask/issues/363)). The directory is
+  not tracked, so the line ignored nothing.
+
+- 2026-10-05: The Chrome end-to-end suite drives both ways the wait for a
+  transaction's receipt ends on the error screen
+  ([#315](https://git.eeqj.de/sneak/AutistMask/issues/315)): lookups that still
+  find no receipt 60 seconds after the broadcast end it with the timeout
+  message, and six lookups that fail in a row end it with the message naming the
+  unreachable network. Done then returns to the address screen. Both cases wait
+  in real time, about a minute each. Playwright's clock would apply to every
+  later test in the run and cannot be removed, and moving the stored broadcast
+  time back can be undone by the save the popup makes every ten seconds.
+
+- 2026-10-05: The Chrome end-to-end suite covers the last of the
+  [#150](https://git.eeqj.de/sneak/AutistMask/issues/150) and
+  [#151](https://git.eeqj.de/sneak/AutistMask/issues/151) items
+  ([#295](https://git.eeqj.de/sneak/AutistMask/issues/295)): a token added on
+  Add Token by its contract address is listed on the address screen;
+  TransactionDetail opened from the token screen leaves that screen on the
+  persisted navigation stack, and Back returns to it; and the token contract row
+  links to the explorer's token page, read off the link rather than followed.
+  The network stub answers `symbol()` and `name()` for the stub token, which
+  adding it reads.
+
+- 2026-10-05: Each control that leads to a signature or to the private key has a
+  test that it refuses a defective wallet before asking for a password
+  ([#254](https://git.eeqj.de/sneak/AutistMask/issues/254)): Send on the main,
+  address and token screens, Export Private Key, and both approval screens, as
+  drawn and as clicked. Send on the confirmation screen refuses it too now,
+  because the popup reopens onto that screen from a saved view. The comments
+  that said the wallet's key cannot be derived now say that
+  `getSignerForAddress` refuses it, and the module comment in
+  `src/shared/walletDefects.js` names both earlier import paths.
+
+- 2026-10-05: The Chrome end-to-end suite drives the private key export screen
+  as it drives the recovery phrase screen
+  ([#253](https://git.eeqj.de/sneak/AutistMask/issues/253)): the correct
+  password shows the key, leaving by the settings gear empties the screen, and
+  leaving while the password is still being checked never puts the key on it.
+  The cases use the imported key wallet rather than the HD one. Leaving drops
+  the address the screen was showing, and an HD wallet's key cannot be derived
+  without it, so on an HD wallet a late decrypt fails by itself and would never
+  exercise the check that discards it. The screen cannot yet be opened twice in
+  one popup session ([#460](https://git.eeqj.de/sneak/AutistMask/issues/460)),
+  so the cases reopen the popup before the second open.
+
+- 2026-10-05: The StateRecovery screen is driven in a real browser under the
+  shipped CSP, in both end-to-end suites
+  ([#361](https://git.eeqj.de/sneak/AutistMask/issues/361)). A stored record
+  this build cannot read opens the popup on it; its export text box holds the
+  record exactly as stored; a near-miss confirmation phrase erases nothing; and
+  the exact phrase erases the record and reloads into Welcome. The cases run
+  before any wallet exists: with no wallet nothing saves on a timer, so no save
+  can write a good record over the unreadable one, and the erase leaves the
+  popup on Welcome for wallet creation.
+
+- 2026-10-05: Escaping in the popup's views follows its own rule with no
+  exceptions ([#329](https://git.eeqj.de/sneak/AutistMask/issues/329)). The
+  decimals and holder count on a token's screen, and every USD figure (the ETH
+  price, each total and each balance row's value), went into `innerHTML`
+  unescaped; they are escaped now. None could carry markup, but `formatUsd()`
+  writes a value under a cent as `< $0.01`. `displaySymbol()` counts a symbol in
+  code points rather than UTF-16 units, so a cut never splits an emoji into a
+  half that renders as U+FFFD. `explorerLink()`, also named in the issue, was
+  already removed by [#168](https://git.eeqj.de/sneak/AutistMask/issues/168).
+
+- 2026-10-05: A Chrome end-to-end test that fails no longer takes later tests
+  down with it ([#318](https://git.eeqj.de/sneak/AutistMask/issues/318)). Each
+  test that turns a fixture switch on for itself alone (a held or failing gas
+  estimate, a seeded native transfer or receipt, a token's lying `decimals()` or
+  markup symbol) turns it off again in a `finally`, and the two tests that drive
+  the popup's own send end on the address screen whether they pass or not,
+  reopening the popup to leave a wait for a receipt. The lying-`decimals()` test
+  checks that nothing was broadcast as soon as the send ends, before it waits
+  for the failure screen, so a broadcast fails it in seconds rather than after a
+  60-second wait. The fixture's `decimals()` override tells 0 from no override,
+  so a token with no decimal places can be fixtured.
+
+- 2026-10-05: Chrome draws the popup in its monospace font
+  ([#418](https://git.eeqj.de/sneak/AutistMask/issues/418)), as Firefox does.
+  Chrome adds a stylesheet of its own to extension pages that sets the font on
+  `body`, and it beat Tailwind's `font-mono`: Tailwind 4 puts its classes in a
+  cascade layer, and a rule outside any layer wins over them. `body` now carries
+  `font-mono!`, which marks the class important. Both end-to-end suites check
+  the popup's font. The same stylesheet also makes Chrome draw the popup's text
+  at 12px rather than the 14px `text-sm` asks for; that is unchanged, and filed
+  as [#456](https://git.eeqj.de/sneak/AutistMask/issues/456).
+
+- 2026-10-05: Dead code removed and copied view helpers shared
+  ([#168](https://git.eeqj.de/sneak/AutistMask/issues/168)). AddressDetail and
+  AddressToken each defined their own `isoDate()` and `timeAgo()` in place of
+  the ones in `src/popup/views/helpers.js`, so a fix to the shared pair would
+  not have reached them. The copies were identical; every screen now uses the
+  shared pair. `blockieHtml()` and `tokenLabel()`, each defined twice, live in
+  `helpers.js` too. Removed as never called: `explorerLink()` (the views build
+  explorer links with `explorerUrl()`), `ETHEREUM_SEPOLIA_CHAIN_ID` (the chain
+  id lives in `src/shared/networks.js`), and `getWalletValue()` and
+  `getTotalValue()`: Home's "Total:" is the active address's total, as
+  `README.md` says. `addressColor()` and `etherscanAddressUrl()` are no longer
+  exported. Nothing the user sees changed.
+
+- 2026-10-05: A prompt raised while another approval window has focus opens a
+  window of its own ([#290](https://git.eeqj.de/sneak/AutistMask/issues/290)).
+  The background centred each approval window on the last focused window, which
+  could be an earlier approval window still open; headless Chrome reports one as
+  1280x720, so the new window came out where the browser refused to create it,
+  and the request failed with no window at all. It now centres only on a browser
+  window, and when the browser refuses the position it asks again without one
+  and lets the browser place the window. In the Chrome end-to-end suite a test
+  could raise its prompt while the previous test's window was still closing, and
+  then either hit that refusal or take the closing window for its own. After a
+  test that passed, the runner now waits a few seconds for approval windows to
+  close and fails the test if one is still open; after a test that failed, it
+  closes them.
+
+- 2026-10-05: The Send screen has a "Max" button
+  ([#198](https://git.eeqj.de/sneak/AutistMask/issues/198)). Emptying an ETH
+  address took guessing an amount and being refused by the confirmation screen's
+  balance check. Max fills in a token's whole balance, cut to the 18 decimal
+  places the confirmation screen accepts, or for ETH the exact balance minus the
+  fee reserve that check gates on, never the four-decimal balance shown; a fee
+  estimate that finishes after the Send screen was left, or its address, holding
+  or recipient changed, fills nothing in. The confirmation screen works a max
+  ETH amount out again from its own fee estimate and signs it with that
+  estimate's fee fields: fetched again at signing, a fee that had risen since
+  would leave amount plus fee above the balance, and the node would refuse the
+  send. A token's maximum is still refused when ETH cannot pay the fee. Where
+  there is nothing to fill in, a flash message says why.
+
+- 2026-10-05: A token scale of zero decimals is tested
+  ([#325](https://git.eeqj.de/sneak/AutistMask/issues/325)).
+  `resolveTokenDecimals()` already used a scale of 0 from the bundled list or
+  from a tracked token, but no test said so: turning either of its `d !== null`
+  checks into a plain truthiness check left every test green while a
+  zero-decimal token fell through to the next source, or to "decimals unknown".
+  The approval tests now assert a scale of 0 from each of those two sources,
+  both where it is resolved and on the approval screen's Amount line. The second
+  half of the issue, one shared `toDecimals()`, had already landed with
+  [#349](https://git.eeqj.de/sneak/AutistMask/issues/349).
+
+- 2026-10-05: The e2e suite waits for a save to land before it closes the popup
+  ([#446](https://git.eeqj.de/sneak/AutistMask/issues/446)). The Settings round
+  trip switched the theme and the network and closed the popup at once, and a
+  close before the save lands loses the switch; with the network left on
+  Sepolia, a dozen later tests failed too. Each Settings switch and spam-filter
+  toggle is now waited for in storage before the close, and `reopenPopup()`
+  waits until the view it expects to reopen on is the saved one. The restore
+  half of the round trip and the second filter toggle change a setting right
+  after a reopen, while the reopened popup's own saves may still be running;
+  they rely on the fix for
+  [#448](https://git.eeqj.de/sneak/AutistMask/issues/448).
+
+- 2026-10-05: A change made while an earlier save from the same page is still
+  running is stored ([#448](https://git.eeqj.de/sneak/AutistMask/issues/448)).
+  `saveStateOnce()` took its baseline from the page's state after the write, so
+  a change made while the save waited on storage counted as already stored and
+  the save queued after it wrote nothing. A setting changed during the read was
+  lost; so was a wallet added, a site revoked or an endpoint changed during the
+  write, and a wallet deleted then stayed in storage. The save now copies the
+  page's fields when it starts, writes from that copy, and keeps the copy as the
+  baseline.
+
+- 2026-10-05: The extension no longer opens a window for a site-connection
+  prompt already answered
+  ([#287](https://git.eeqj.de/sneak/AutistMask/issues/287)). When the prompt was
+  decided before the toolbar popup raised for it had loaded, that popup was torn
+  down, `chrome.action.openPopup()` rejected, and the background opened its
+  fallback window for the answered approval and then removed it. In the Chrome
+  end-to-end suite the next test could take that window for its own prompt and
+  lose it under its wait. `openApprovalWindow()` now opens nothing for an
+  approval that is no longer pending. The blocklist test's Reject, whose window
+  closes itself, is clicked as the other site Reject is, with the click
+  witnessed. Making `e2e-chrome` a required check is still blocked: other
+  reports of the Chrome suite failing under load are open, among them
+  [#290](https://git.eeqj.de/sneak/AutistMask/issues/290) and
+  [#446](https://git.eeqj.de/sneak/AutistMask/issues/446), as `README.md` says.
+
+- 2026-10-05: The lost-password delete confirmation refuses an empty field and
+  ignores characters that paint nothing
+  ([#336](https://git.eeqj.de/sneak/AutistMask/issues/336)). A wallet named only
+  with spaces compared equal to an empty field, so typing nothing would have
+  deleted it, and a zero-width space in a name made the name impossible to type
+  back. An empty field is now refused whatever the name is, the same invisible
+  characters `src/shared/symbolSpoof.js` strips are removed from both sides, and
+  a name that shows nothing is shown and typed back as "Wallet N".
+
+- 2026-10-05: A `holders_count` that is not a whole number in plain digits is
+  unknown, not read in part
+  ([#251](https://git.eeqj.de/sneak/AutistMask/issues/251)). `parseInt` read
+  `1,000` as 1, `0x10` as 0 and `1e3` as 1, a reported low count that hides the
+  token in the transaction history and the send-screen token selector. A count
+  above `Number.MAX_SAFE_INTEGER` is unknown too, not rounded or `Infinity`. The
+  balance list's `holders !== null` check, which did nothing, is dropped.
+  `README.md` and `docs/README.md` now say how each filter treats an unknown
+  count and that the token screen leaves out its "Holders:" row then, and
+  `README.md` lists `src/shared/holders.js`.
+
+- 2026-10-04: A popup boot in the tests loads transactions without failing
+  ([#429](https://git.eeqj.de/sneak/AutistMask/issues/429)). The stand-in for
+  `filterTransactions` in `tests/support/popupBoot.js` returned a bare list,
+  while the real one returns `{ transactions, newFraudContracts }`, so every
+  boot onto Home, AddressDetail or AddressToken failed inside its transaction
+  loading and logged `loadHomeTxs failed` or `loadTransactions failed`; the rest
+  of that code never ran. The stand-in now returns the real shape, and
+  `tests/persistedFieldContract.test.js` boots onto each of the three and
+  asserts neither message is logged. `make test` time did not change measurably.
+
+- 2026-10-04: The native token's label follows the network
+  ([#372](https://git.eeqj.de/sneak/AutistMask/issues/372)). `networks.js` gives
+  each network a `nativeCurrency` and nothing read it: every screen wrote `ETH`,
+  so on Sepolia the balance, the value and the fee all read `ETH`. Every native
+  figure now reads `nativeCurrency`, which is `ETH` on mainnet and `SepoliaETH`
+  on Sepolia: the balance lists, Send and confirmation screens and the
+  contract-recipient warning the active network's; the approval, wait, success,
+  error and transaction detail screens, the transaction history and the refusal
+  of a fee above the limit that of the network the transaction's chain id names.
+  A token claiming any network's `nativeCurrency` is dropped as a fake, as one
+  claiming `ETH` already was, and the transaction detail screen calls an entry a
+  token transfer when it has a token contract, not by its symbol.
+- 2026-10-04: A popup that is already open when the stored profile becomes
+  unreadable moves to the recovery screen
+  ([#373](https://git.eeqj.de/sneak/AutistMask/issues/373)). It used to stay on
+  the last good profile, with the "NOT SAVED" banner at most, until reopened.
+  Every save already ran the check the popup runs at open, so the popup finds
+  the record at the next navigation or ten-second refresh, whether or not the
+  network answers; a save that fails that check now raises the recovery screen
+  and stops the refresh. The screen it replaces is left as any navigation leaves
+  it, so a revealed phrase or key or a typed password is wiped. Once up, nothing
+  else in that popup can replace it, and a later save or a transaction wait that
+  ends does not clear an export or a typed confirmation. It is never saved as
+  the current view, so a popup opened after the record is erased in another
+  window opens normally. Any other failed save still gets the banner and leaves
+  the screen alone.
 - 2026-10-04: A swap whose deadline is later than a JavaScript date can hold is
   decoded ([#437](https://git.eeqj.de/sneak/AutistMask/issues/437)). A date
   reaches only to 275760-09-13, so a later deadline, such as the `uint256`
