fix: count the network fee in the confirm-screen balance check (closes #154 )

The Send button was enabled whenever the amount alone fit the balance, so
a max-value ETH send passed the confirmation screen and failed at
broadcast, after the user had committed to it.

The arithmetic moves into src/shared/txValidation.js as a pure function
over 18-decimal fixed point: native ETH now requires amount + fee <=
balance, and an ERC-20 transfer requires the ETH balance to cover the fee
on top of the token check, reported as its own error. Validation re-runs
when the async estimate resolves; Send stays disabled while the estimate
is pending and when it fails, so an unknown fee is never treated as zero.
The fee messages are static elements that already reserve their space, so
nothing moves when the estimate lands.

The fee reserved is the one the node will actually require. The send pins
no fee fields, so ethers broadcasts a type-2 transaction and the node
validates it against value + gasLimit * maxFeePerGas; gating on gasPrice
would under-reserve by roughly gasLimit * baseFee and let through exactly
the broadcast failure this change exists to prevent. feeReserveWei()
derives that reserve, falling back to gasPrice only where no type-2
pricing exists. The reserve is read when the screen opens and the
broadcast derives its own, so a base fee that roughly doubles while the
user is at the password field can still outrun it: this turns a
deterministic failure on every max-value send into a rare one, not into
none.

The fee line shows both numbers rather than one - what the transfer is
expected to cost, and below it the larger amount reserved until it
confirms. Quoting only the reserve overstates the typical mainnet cost by
roughly double on every send; quoting only the estimate contradicts the
gate. The second line holds its space from the first paint.

validateTransfer() fails closed: a feeWei that is not a non-negative
bigint under FEE_KNOWN, any unrecognised feeStatus, and a negative amount
all block, rather than counting as a fee of zero or as an amount that
passes every comparison trivially.

Raw Blame History

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. 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, 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: add ESLint to script/lint. make check is prettier --check only today and cannot catch undefined identifiers, which is how #150 and #151 shipped.

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).
2026-08-11: UTC Timestamps checkbox moved from the Token Spam Protection well into Display, next to the theme selector (#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).
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).
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).
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).
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).
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).
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).
2026-08-11: Three README.md claims corrected against the code — blocklist attribution, token-display rule, navigation model (#213).
2026-08-11: README Screen Map rebuilt from the code — every screen, element and transition re-verified against src/popup/ (#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).
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).
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).
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).
2026-08-11: TODO.md Workflow rewritten to the branch-and-PR-per-issue model on next, with Status and Next Step refreshed (#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).
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 and #184.
Cut 1.0.0 once the milestone is empty, then continue tagging as milestones land.
