 ### Debug Builds
 `make build` always produces a release build: the build-time `DEBUG` constant is
 `false`, so wallet creation uses real entropy and the red banner is off. To
 produce a debug build instead, set `AUTISTMASK_DEBUG=1` in the environment:
 ```bash
 make build-debug          # or: AUTISTMASK_DEBUG=1 make build
 ```
 Only the exact value `1` enables it; any other value (including unset, empty, or
 `true`) yields a release build, so a typo cannot accidentally ship the debug
 behavior. The build prints which mode it used. See the
 [DEBUG Mode Policy](#debug-mode-policy) for what the flag changes. **Never
 distribute a debug build** — every wallet it creates gets the same publicly
 known test recovery phrase.
 Both builds end by running `script/verify-build`, which reads the compiled
 `DEBUG` state back out of the emitted bundles and fails the build if it is not
 the one that was asked for. The test suite cannot check this: it loads
 `src/shared/constants.js` outside a bundle, so it only ever sees the fallback
 value. The assertion is on the artifacts because that is where the property
 lives.

 ## End-to-End Tests
 `make test-e2e` builds `dist/chrome/` and drives the **real popup in a real
 Chrome**, loaded as an unpacked MV3 extension inside a pinned
 `mcr.microsoft.com/playwright` container (pinned by digest in `script/test-e2e`;
 docker is required and the suite fails loudly rather than skipping if it is
 unavailable). The suite lives in `tests/e2e/` and is driven by
 `playwright-core`, whose version must stay matched to the container's Playwright
 version — the browsers ship inside the image.
 It covers popup load, wallet creation through the UI, the Add Token screen and
 the transaction detail screen for an ERC-20 transfer. All outbound network is
 intercepted at the browser level and served from fixtures in
 `tests/e2e/network.js`, so the run is deterministic and fully offline;
 unrecognised outbound requests are reported as failures rather than silently
 allowed.
 That reporting has one bound worth knowing. Observation ends when the browser
 context is torn down, and nothing can watch traffic after that, so the run keeps
 collecting for a fixed grace period after the last test returns
 (`TRAILING_WATCH_MS` in `tests/e2e/run.js`, currently 1500ms) and then closes
 the context. A request whose _first_ dispatch falls after that window is never
 seen at all and cannot fail the run. In practice a request a test fires without
 awaiting reaches the route handler about 10ms later, and anything on a repeating
 timer gets observed on an earlier tick during the ~20s suite — but a one-shot
 call deliberately deferred past the window will escape.
 That interception covers the MV3 background service worker as well as the popup
 page, which it does not by default — `script/test-e2e` sets
 `PW_EXPERIMENTAL_SERVICE_WORKER_NETWORK_EVENTS=1` for it. Because that flag is
 experimental, the harness does not take it on trust. At launch it waits for the
 background worker's **own** startup request — the phishing blocklist fetch that
 `src/background/index.js` issues unconditionally — to arrive in the route
 handler, and aborts the entire suite if none does within 30 seconds
 (`tests/e2e/harness.js`). The check is passive on purpose: a synthetic probe
 fetched from inside the worker via `worker.evaluate()` was tried first and
 rejected, because evaluating in an extension service worker that early kills the
 worker outright, destroying the thing being measured. Observing traffic the
 extension already generates perturbs nothing. Losing the race fails closed — the
 suite refuses to run rather than passing quietly.
 As defence in depth, Chrome is also started with
 `--host-resolver-rules=MAP * ~NOTFOUND`, so a request that ever did slip past
 the route handler could not resolve a host at all. That only bounds the damage;
 detecting escaping traffic remains the canary's job. To see what is actually
 being intercepted, run with `E2E_TRACE_NETWORK=1` and every routed request is
 printed, tagged `[sw]` or `[page]`.
 **Any uncaught page error or `console.error` fails the run.** That is the point:
 a `ReferenceError` from a used-but-not-imported identifier is invisible to
 `make check` (`script/lint` is only `prettier --check`) but fatal in a browser,
 and this suite exists because exactly that class of bug shipped twice.
 `make test-e2e` is deliberately **not** part of `make check` or `make test`.
 `REPO_POLICIES.md` caps `make test` at 20 seconds and a browser suite does not
 fit; nothing in `tests/e2e/` is named `*.test.js`, so jest cannot pick it up
 either. It is also not wired into the Gitea workflow yet — docker-in-docker in
 CI is a separate question. Run it locally before changing anything under
 `src/popup/views/`.

+- An **address** holds ETH and any user-added ERC-20 tokens.
    - An **xprv wallet** (`type: "xprv"`, extended private key): the same
      multi-address behavior as an HD wallet, including the "+" button and the
      address scan on import, but imported from an extended private key rather
      than a recovery phrase. It therefore has no recovery phrase to display or
      back up.
 - An **address** holds ETH and ERC-20 tokens.
 - The user can have multiple wallets, each with multiple addresses (HD) or a
  single address (key).
 Which tokens an address shows is decided by `fetchTokenBalances()` in
 `src/shared/balances.js`, from the Blockscout `token-balances` response, so
 tokens do appear without the user adding them. An ERC-20 is shown when its
 balance is nonzero and it is in the bundled top-250 token list, is tracked by
 the user, or has 1,000 or more holders; a token claiming a symbol from the
 bundled list from any other contract address is always dropped. That filter is
 unconditional — the "Hide tokens with fewer than 1,000 holders" setting governs
 the transaction history and the send-screen token selector, not this list.
 Tracked tokens with a zero balance are listed as well while "Show tracked tokens
 with zero balance" is on.

 Adding new DEBUG-conditional branches requires explicit approval from the
 project owner.
 `DEBUG` is a build-time constant, not a runtime setting. `build.js` injects it
 into the bundle as the `__BUILD_DEBUG__` define — `false` unless the build was
 run with `AUTISTMASK_DEBUG=1` (see [Debug Builds](#debug-builds)) — and
 `src/shared/constants.js` reads it. It cannot be changed after the bundle is
 produced.
 The debug-mode toggle in settings is a separate, runtime-only flag. It raises
 the log level and turns the banner on, and that is all it may ever do: it feeds
 `isDebug()` in `src/shared/log.js`, which is deliberately not what
 `generateMnemonic()` consults. Mnemonic generation reads the build-time `DEBUG`
 constant directly, so no runtime toggle in a release build can reach the
 hardcoded test phrase.

 # Completed Steps
 - 2026-08-11: `script/verify-build` now walks `dist/` NUL-delimited and asserts
  `dist/` is a real directory, so a path with a trailing space or a newline can
  no longer carry a debug marker past the unlisted-bundle check
  ([#223](https://git.eeqj.de/sneak/AutistMask/issues/223)).
 - 2026-08-11: Policy compliance sweep — conditional verbose test rerun, local
  Tailwind binary instead of `npx`, `--frozen-lockfile` on `make install`, and
  the Makefile-only targets documented in the README
  ([#166](https://git.eeqj.de/sneak/AutistMask/issues/166)).
 - 2026-08-11: `script/verify-build` diagnostics corrected: the both-markers
  message now states what is and is not proven, an unreadable bundle is
  diagnosed as an I/O fault rather than as changed output, the `*.js` assumption
  lives only in `build.js`, and the unlisted-bundle scan hard-fails when it
  cannot enumerate `dist/`
  ([#180](https://git.eeqj.de/sneak/AutistMask/issues/180)).
 - 2026-08-11: Three `README.md` claims corrected against the code — blocklist
  attribution, token-display rule, navigation model
  ([#213](https://git.eeqj.de/sneak/AutistMask/issues/213)).
 - 2026-08-11: README Screen Map rebuilt from the code — every screen, element
  and transition re-verified against `src/popup/`
  ([#164](https://git.eeqj.de/sneak/AutistMask/issues/164)).
 - 2026-08-11: `docs/README.md` rewritten against the code: no competitor names,
  all five network destinations documented, password/Settings/Add Wallet
  sections corrected ([#163](https://git.eeqj.de/sneak/AutistMask/issues/163)).
 - 2026-08-11: `loadState()` now derives `hasWallet` from the wallet list instead
  of trusting the persisted flag, so a profile already saved inconsistent no
  longer stays broken on every load
  ([#195](https://git.eeqj.de/sneak/AutistMask/issues/195)).
 - 2026-08-11: Wallet deletion repairs its own state — `hasWallet` follows the
  remaining wallets, the selection only moves when it was deleted, and the
  active-address change is broadcast to connected sites
  ([#156](https://git.eeqj.de/sneak/AutistMask/issues/156)).
 - 2026-08-11: One row per on-chain value movement in transaction history: the
  merge moved into the pure `mergeTransactions` and the zero-ETH native side of
  a plain ERC-20 transfer absorbed into its token row
  ([#177](https://git.eeqj.de/sneak/AutistMask/issues/177)).
 - 2026-08-11: `TODO.md` Workflow rewritten to the branch-and-PR-per-issue model
  on `next`, with Status and Next Step refreshed
  ([#191](https://git.eeqj.de/sneak/AutistMask/issues/191)).
 - 2026-08-09: `DEBUG` became a build-time constant defaulting to off, injected
  as the `__BUILD_DEBUG__` esbuild define and turned on with
  `AUTISTMASK_DEBUG=1`, so a plain `make build` no longer hands every newly
  created wallet the publicly committed test recovery phrase
  ([#149](https://git.eeqj.de/sneak/AutistMask/issues/149)).
 - 2026-08-09: dApp approval signing moved into the popup — the password no

 **Phishing domain blocklist** (`raw.githubusercontent.com`)
 A community-maintained list of phishing domains, used to warn you when a site
 that asks to connect, or to have a transaction or signature approved, is a known
 scam. A copy is bundled into the extension at build time, so the protection
 works before any network request happens. At runtime the extension fetches the
 live list to pick up newly added domains, keeping only the entries not already
 in the bundled copy (persisted locally if under 256 KiB). This endpoint is not
 user-configurable.
 When it is contacted: once when the background script starts, and every 24 hours
 after that. It is a plain download of a public file — nothing about you is sent,
 but the host sees your IP address. If the fetch fails, the bundled copy is still
 used.
 **Etherscan address labels** (`etherscan.io`; `sepolia.etherscan.io` on Sepolia)
 When you review a send, AutistMask fetches the recipient's public Etherscan
 address page and looks for a "Fake_Phishing"/"Phish/Hack" label or a scam
 warning, and shows a red warning if it finds one. This is a plain page fetch
 with no API key, made by your browser. It is best-effort: if it fails, it is
 silently ignored. This endpoint is not user-configurable.
 When it is contacted: each time you reach the send confirmation screen.
 What gets sent: the recipient address you are about to send to, and your IP
 address. Your own addresses are not sent.
 Etherscan links shown elsewhere in the UI (on addresses, transactions, and token
 contracts) are ordinary links. They contact nothing until you click them.

 # The manifest says which bundles must carry a marker. This says no other
 # emitted file may carry one, which catches a manifest that has gone stale
 # or short rather than trusting whatever it happens to list.
 #
 # Deliberately unfiltered by extension. build.js selects manifest entries with
 # an endsWith(".js") test; repeating that literal here would mean a bundle
 # emitted under some other extension escaped the manifest AND this check at
 # once, which is the correlated blind spot the two-source design exists to
 # avoid. Every regular file and every symlink under dist/ is searched — that
 # is the whole of what a build emits — so build.js's filter is the only place
 # the assumption lives and this check is what catches it being wrong.
 #
 # That claim only holds if the walk is exhaustive and every name survives it
 # intact, so four things are enforced here rather than assumed:
 #
 #   - the walk is NUL-delimited and the paths reach the check as arguments, so
 #     no name can be reshaped on the way in. Read line by line, a name with a
 #     trailing space lost it to read's field splitting and the remnant then
 #     matched a manifest line, and a name containing a newline arrived as a
 #     listed path plus an empty one. Both left a marker-carrying, unlisted file
 #     unchecked while the script still reported success. Delivering such a name
 #     intact is only half of it; is_listed also has to keep it out of grep's
 #     pattern, for the same reason.
 #   - find's exit status is checked. A subtree it cannot descend is reported on
 #     stderr and then simply missing from the listing, so an unchecked status
 #     turns "could not look" into "nothing was there" — the same conflation
 #     has_marker exists to prevent. The status cannot be read off a pipeline,
 #     so the listing lands in a file that xargs then reads back.
 #   - symlinks are walked too (-type l), not skipped. A marker-carrying bundle
 #     reachable under an unlisted path in dist/ is a stale manifest whether the
 #     path is a link or a file, and grep reads through the link. A link that
 #     cannot be read through — dangling, or pointing at a directory — fails
 #     hard via has_marker's exit-2 path, which is the fail-closed answer: the
 #     build emits neither, so their DEBUG state is unproven, not fine.
 #   - dist/ itself must be a directory and not a symlink, which main asserts
 #     before anything reads through it. find does not follow a symlink named on
 #     its own command line, so a linked dist/ collapses this walk to one entry
 #     and cross-checks nothing.
 #
 # Types other than regular files and symlinks are left out on purpose: a build
