Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This PR adds state-backed deployment authorization, but legacy chains may silently activate enforcement at a different block when their prior dynamic activation configuration is migrated, and the precompile documentation does not clearly state that a non-zero administrator is required. These configuration and rollout risks should be fixed or explicitly accepted before merging. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Empty allowlists in static mode still disable gating. Dynamic mode now denies when the genesis baseline is empty, and admin-only chainspecs default activation height to 0. Pass the shared baseline Arc into the precompile instead of cloning a Vec.

deployAllowlistPrecompileActivationHeightwas a supported chainspec field before this unification. The current deserializer ignores it, so a legacy chainspec with different activation heights can make current and older nodes enforce deployment permissions at different blocks. Parse the legacy field and reject it with migration guidance, or require it to equaldeployAllowlistActivationHeight.🤖 Prompt for AI Agents

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Specify that the admin must be non-zero.
deployAllowlistAdmin may be configured as the zero address, but that preserves legacy behavior and does not install F102. Change this sentence to say “when a non-zero deployAllowlistAdmin is configured” so it matches the guide and ADR.

Everything looks good to me, should be fully backwards compatible with the existing deployAllowList, but maybe we could add some tests to ensure this,
something like chain_without_any_deploy_allowlist_config_is_fully_unrestricted or legacy_static_chain_never_installs_deploy_permissions_precompile

Summary
Verification
Rollout
Chains without a non-zero deployAllowlistAdmin retain legacy behavior. Dynamic permissions activate at deployAllowlistActivationHeight. Existing networks can opt in only while that configured height is still in the future; networks whose static activation already passed require a separate coordinated consensus upgrade mechanism.
