# Workflow

- `git pull` `next` and cut a branch from it — one branch per issue, named
  `issue-<N>-<slug>`. Never branch from `main`.
- Do the work as one commit whose title ends with ` (closes #N)`, with the
  `TODO.md` update in that same commit.
- Move Next Step to the top of Completed Steps; move the top item of Future
  Steps into Next Step.
- Run `make fmt`, then `make check`. A feature branch may be red; `next` and
  `main` may not.
- Rebase onto current `next` immediately before pushing — other branches land on
  `next` continuously — and re-run `make check` after resolving, because a clean
  textual merge can still break the build.
- Push the branch and open one PR per issue with base `next`. Never base `main`.
- An independent reviewer who did not write the change gates the merge. On a
  passed review the PR is squash-merged into `next`.
- `next` is the branch for the next milestone. It is kept green and mergeable to
  `main` at any moment, without notice.
- `main` receives exactly one PR per milestone, from `next`. Releases are tagged
  from `main`.

# Status

pre-1.0, working towards the 1.0.0 milestone. Tagged v0.1.0 on 2026-02-27. The
milestone is in flight on `next`; its `next` -> `main` PR is
[#190](https://git.eeqj.de/sneak/AutistMask/pulls/190). `make check` verified
green on `next` at `e9fa8be` on 2026-08-10, and `make build` produces
`dist/chrome/` and `dist/firefox/` with every bundle verified to have `DEBUG`
compiled off.

The backlog lives on the
[Gitea tracker](https://git.eeqj.de/sneak/AutistMask/issues), which is
authoritative; this file does not duplicate it. Full policy file set present. A
real-browser end-to-end suite (`make test-e2e`) now sits alongside `make check`,
which cannot see a runtime `ReferenceError` in a popup view.

# Next Step

Land [#152](https://git.eeqj.de/sneak/AutistMask/issues/152): add ESLint to
`script/lint`. `make check` is `prettier --check` only today and cannot catch
undefined identifiers, which is how
[#150](https://git.eeqj.de/sneak/AutistMask/issues/150) and
[#151](https://git.eeqj.de/sneak/AutistMask/issues/151) shipped.

# Completed Steps

- 2026-08-12: The restored navigation stack is filtered against
  `RESTORABLE_VIEWS` on load, truncated at the first entry the popup would not
  render so that every surviving entry keeps the Back target it had. Reopening
  the popup can no longer put Back onto a screen whose content is never
  re-rendered, such as `export-privkey` or `show-phrase`
  ([#224](https://git.eeqj.de/sneak/AutistMask/issues/224)).
- 2026-08-12: The dust threshold field now explains a rejection instead of
  snapping back in silence, with the parse in a pure, unit-tested module that
  accepts plain decimal digits only — hex and exponent notation are refused
  rather than read as 16 and 1000
  ([#233](https://git.eeqj.de/sneak/AutistMask/issues/233)).
- 2026-08-12: Approval verification became an allowlist — transaction type
  restricted to 0/1/2 so an EIP-7702 delegation can no longer ride along on an
  approved transfer, every consequential field compared, the artifact
  re-serialized from the checked fields alone and its exact bytes required to be
  the canonical encoding of what was broadcast. One approval now yields at most
  one broadcast, and every path that retires a pending approval — popup close,
  active-address change, a late reject — goes through a single chokepoint that
  refuses to settle an attempt already claimed for signing and broadcast
  ([#174](https://git.eeqj.de/sneak/AutistMask/issues/174)).
- 2026-08-12: An address can be removed from an HD or xprv wallet behind a
  confirmation screen that states nothing is destroyed, sharing the deletion
  state transitions with wallet deletion so the selection, site permissions and
  active-address broadcast follow the same rules
  ([#162](https://git.eeqj.de/sneak/AutistMask/issues/162)).
- 2026-08-12: The known-symbol spoof rule moved into `src/shared/symbolSpoof.js`
  and is now the only copy. The balance list had exempted symbols the token list
  maps to `null` — `"ETH"` alone — so a fake ETH ERC-20 was hidden from the
  transaction history and the Send selector but listed as a holding named ETH. A
  symbol with no legitimate contract may now be borne by no contract on any of
  the three surfaces, and the native exemption is "has no contract address", so
  a second null-mapped symbol needs no call-site change. The user's real ETH
  balance is read over RPC and never passes through the rule
  ([#235](https://git.eeqj.de/sneak/AutistMask/issues/235)).
- 2026-08-12: `script/verify-build`'s failure modes are now a committed target,
  `script/test-verify-build`, run by `make check`. It asserts the exit status
  and the message of every case against a fixture tree in a temp dir, and drops
  privileges (proving the runner against a mode-000 file first) for the cases
  that only mean something when file permissions are in force
  ([#227](https://git.eeqj.de/sneak/AutistMask/issues/227)).
- 2026-08-12: WaitTx lifecycle: a receipt and the 60-second timeout can no
  longer both render on one tick, no timer or in-flight lookup outlives its
  wait, a failed receipt lookup no longer counts as a timeout (but six in a row
  end the wait, reported as an unreachable network rather than as a timeout),
  and the wait now resumes after a popup close
  ([#155](https://git.eeqj.de/sneak/AutistMask/issues/155)).
- 2026-08-12: The private key export screen now wipes the key from the page
  whenever it is left by any route, and a decrypt still in flight when the
  screen is left is discarded instead of written; the same `onViewLeave()`
  cleanup was extended to every other screen holding secret material in the DOM
  (AddWallet, ConfirmTx, DeleteWallet, ApproveTx, ApproveSign)
  ([#221](https://git.eeqj.de/sneak/AutistMask/issues/221)).
- 2026-08-12: An xprv wallet already in storage that was imported from a
  non-master key is detected from the depth of its stored `xpub`, explained in
  the wallet list, and blocked from signing, sending and private-key export
  instead of throwing on the send screen
  ([#234](https://git.eeqj.de/sneak/AutistMask/issues/234)).
- 2026-08-12: An unreported `holders_count` is now parsed as `null` rather than
  `0`, so the low-holder rule declines to judge an unknown count instead of
  hiding a legitimate token as spam, in both the transaction history and the
  Send token selector ([#230](https://git.eeqj.de/sneak/AutistMask/issues/230)).
- 2026-08-12: Bundled token list documentation no longer states a count. The
  four "top 250" claims in `README.md` and the "roughly 500" claim in
  `docs/README.md` are replaced with a description of how the list is actually
  selected — a point-in-time CoinGecko snapshot of the highest-market-cap
  Ethereum mainnet ERC-20s — with `TOKENS` in `src/shared/tokenList.js` named as
  the authoritative set
  ([#239](https://git.eeqj.de/sneak/AutistMask/issues/239)).
- 2026-08-11: libsodium runs on WebAssembly in the shipped builds —
  `'wasm-unsafe-eval'` added to both manifest CSPs after measuring the wasm2js
  fallback at 20x the Argon2id cost, pinned in both directions by
  `tests/manifest.test.js` and observed in the real popup by the e2e suite
  ([#182](https://git.eeqj.de/sneak/AutistMask/issues/182)).
- 2026-08-11: Known-symbol spoof verification became a Settings toggle
  (`hideSpoofedSymbols`), on by default, governing the transaction-history
  filter and the fraud-contract learning it feeds
  ([#176](https://git.eeqj.de/sneak/AutistMask/issues/176)).
- 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: UTC Timestamps checkbox moved from the Token Spam Protection well
  into Display, next to the theme selector
  ([#212](https://git.eeqj.de/sneak/AutistMask/issues/212)).
- 2026-08-11: Network fee counted in the confirmation-screen balance check for
  both ETH and ERC-20 sends, reserving what the node actually charges a type-2
  transaction, with the arithmetic in a pure, unit-tested
  `src/shared/txValidation.js`
  ([#154](https://git.eeqj.de/sneak/AutistMask/issues/154)).
- 2026-08-11: A dust threshold of `0` now means "hide nothing" instead of
  falling back to the 100,000 gwei default, and every address comparison in
  `src/shared/transactions.js` goes through one case-normalising helper so a
  checksummed genuine contract is no longer read as a spoof
  ([#179](https://git.eeqj.de/sneak/AutistMask/issues/179)).
- 2026-08-11: Password-gated recovery phrase display for HD wallets, reached
  from the wallet row in Settings, wiped on leaving the screen and excluded from
  the views the popup can reopen onto
  ([#161](https://git.eeqj.de/sneak/AutistMask/issues/161)).
- 2026-08-11: Extended-key import hardened — the base58 checksum is now enforced
  on every xprv and xpub, and a non-master key is refused with an explanation
  instead of being derived beneath
  ([#210](https://git.eeqj.de/sneak/AutistMask/issues/210)).
- 2026-08-11: the balance refresh and the 24-hour phishing list refresh moved
  from `setInterval` to the extension alarms API, with the phishing delta and
  its fetch timestamps persisted to extension storage, so neither job dies with
  the MV3 service worker. Each job's freshness guard was decoupled from its
  alarm period at the same time — timed to the period, a guard vetoes its own
  scheduled tick and halves the real refresh rate
  ([#158](https://git.eeqj.de/sneak/AutistMask/issues/158)).
- 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: Known-answer test coverage for the crypto core — BIP-39/BIP-32
  derivation in `wallet.js` and the Argon2id vault in `vault.js`
  ([#159](https://git.eeqj.de/sneak/AutistMask/issues/159)).
- 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
  longer crosses the extension messaging boundary; the background broadcasts and
  resolves approvals only, and verifies the signed artifact against the approval
  it holds (#157).
- 2026-08-09: Post-build assertion that every emitted bundle containing
  `constants.js` has `DEBUG` compiled off, via `script/verify-build` on the
  `make build` path (#170).
- 2026-08-09: Containerized Chrome end-to-end harness (`make test-e2e` /
  `script/test-e2e`) driving the real popup with all network intercepted, plus
  the two used-but-not-imported crashes it caught: AddToken unreachable (#150)
  and TransactionDetail broken for every ERC-20 transfer (#151). Harness
  demonstrated failing before the fixes and passing after (#181). Interception
  covers the MV3 background service worker, not just the popup page, and a
  launch-time canary aborts the suite if worker traffic starts escaping.
- 2026-08-09: Reviewed the repo end to end and filed the 1.0.0 backlog
  (#149-#168).
- 2026-08-09: Test coverage for the address-poisoning defense in
  `src/shared/transactions.js` (#160)
- 2026-07-26: About well in settings with build info, repo link and the version
  click easter egg (#145); proper view navigation stack (#146).
- 2026-07-07 Adopted scripts-to-rule-them-all: `script/` entrypoints, Makefile
  shims, README Entrypoints section (#148)
- 2026-03-01: USD display suppressed on testnets (#142); estimated USD for ETH
  in approve-tx view (#141).
- Sepolia testnet support (#137); etherscan links go to token-specific URLs
  (#136).
- Transaction detail improvements: Type field and on-chain details (#130),
  txid-first reordering (#133), swap display corrections (#128), expanded
  confirm-tx warnings (#118).
- Dark mode theme setting (Light/Dark/System) with contrast fixes (#126);
  timestamps include timezone offset (#120); layout shift audit, reserved space
  for error messages (#124).
- Copy-flash visual feedback with timing tune (#113, #121); cross-wallet-type
  duplicate detection (#115).
- 2026-02-27: v0.1.0 tagged.
- 2026-02-24: Initial scaffolding: popup UI, BIP-39 wallet creation via
  ethers.js, wallet persistence, real ETH balances over RPC, ENS forward and
  reverse resolution.

# Future Steps

Only work that has no issue of its own belongs here; everything else is on the
tracker.

- Pre-1.0 security review of the extension (key handling, DEBUG mode policy, RPC
  input validation) before any 1.0rc tag. Individual filed issues are parts of
  it, but the review is broader than any of them.
- Decide whether docker-in-docker makes `make test-e2e` runnable in the Gitea
  workflow. Extending the suite itself is tracked as
  [#183](https://git.eeqj.de/sneak/AutistMask/issues/183) and
  [#184](https://git.eeqj.de/sneak/AutistMask/issues/184).
- Cut 1.0.0 once the milestone is empty, then continue tagging as milestones
  land.
