Transfer L1 ownership of the Swell chain (chainId 1923) from the standard OP Mainnet L1PAO Safe to AltLayer's new owner Safe, moving the ProxyAdmin and DisputeGameFactory via the TransferOwners template as Swell winds down. Split out of the combined Swell/Dust/Unichain handover branch into its own PR. The Swell L2 ProxyAdmin owner is intentionally left unchanged (the L2PAO follow-up task is not being done), so the prior references to it have been removed from the README and config. Status: DRAFT, NOT READY TO SIGN — requires Optimism Governance approval. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
CI simulates the stack 053 → 054 → 055; the preceding U19 tasks consume Safe nonces before 055 runs, so the pinned overrides must be stack-adjusted: - L1PAO 0x5a0Aae… 35 → 36 (task 053 executes via this Safe) - FoundationUpgradeSafe 57 → 59 (tasks 053 and 054 both nest it) - SecurityCouncil 58 → 60 (tasks 053 and 054 both nest it) Regenerated the FoundationUpgradeSafe and SecurityCouncil message hashes in VALIDATION.md from the stacked simulation (domain hashes unchanged) and updated the L1PAO nonce state change to 36 → 37. Both `simulate-stack` runs (foundation, council) now pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Summary
Adds task
055-swell-l1-ownership-transfers, which transfers L1 ownership of the Swell chain (chainId 1923) from the standard OP Mainnet L1PAO Safe (0x5a0Aae59D09fccBdDb6C6CcEB07B7279367C3d2A) to AltLayer's new owner Safe (0xa83F1334c6a8Daca576Dc14020d9d2b1b16a8Dfa). Swell is winding down and AltLayer is taking over to finish the wind-down.Contracts moved via the

Swell has been removed from the public superchain-registry (ethereum-optimism/superchain-registry#1247); its addresses are loaded via
fallbackAddressesJsonPathfromaddresses.json(verified withop-fetcher) and it reuses OP Mainnet's standard SuperchainConfig.Status
DRAFT, NOT READY TO SIGN— requires Optimism Governance approval before signing. Domain/message hashes inVALIDATION.mdwere generated at task creation (2026-06-15) with pinned Safe nonces; live nonces must be re-verified and the task re-simulated before signing.🤖 Generated with Claude Code
