Description
Lets new chains start with
CANNON_KONAas the selected initial fault game when deploy inputs include a real starting anchor root and nonzero prestate. LegacyCANNONremains rejected for initial deployments.For non-super-root permissionless deploys, this also registers
PERMISSIONED_CANNONfrom genesis as the guardian fallback while keepingCANNON_KONArespected.Tests
Updated deploy/OPCM coverage for selected
CANNON_KONAinitial deploys, permissioned fallback registration/use, legacyCANNONrejection, zero/prestate/root validation, placeholder-root rejection for permissionless deploys, super-root rejection, and unchanged permissioned deploys.Additional context
#21625 deprecated legacy
CANNON, so this PR implements #20913 forCANNON_KONAonly. The0xdeadanchor remains allowed only for permissioned deploys until follow-up PR #21610 wires real pipeline state.The permissioned fallback preserves the standard OP Stack emergency path for retiring an unsound permissionless game.
