No High findings were reported.

Detailed triage

L-1 Centralization Risk

This contract family is explicitly administrative compliance infrastructure. RuleEngine (RBAC), RuleEngineOwnable, and RuleEngineOwnable2Step intentionally expose privileged operations for rule and token binding governance. This is a product requirement, not a vulnerability.

L-2 Unspecific Solidity Pragma

^0.8.20 is intentional for integrator compatibility. Build tooling remains pinned (Solc 0.8.34). This is a common and acceptable pattern for reusable contract packages.

L-3 PUSH0 Opcode

The project target is modern EVM (prague). PUSH0 compatibility concerns only pre-Shanghai targets; those are outside the supported deployment matrix.

L-4 Modifier Invoked Only Once

onlyRulesLimitManager being used once is not a risk. It preserves the same extensible access-control abstraction used across modules and variants.

L-5 Empty Block

Empty bodies in _onlyComplianceManager, _onlyRulesManager, and _onlyRulesLimitManager are intentional. Authorization executes in the modifier, and the empty body enforces a clean virtual-hook architecture.

L-6 Loop Contains require/revert

setRules must be all-or-nothing. Reverting on invalid element prevents partial updates and inconsistent policy state.

L-7 Costly operations inside loop

EnumerableSet.add in a loop is unavoidable for persistent rule set updates. Cost scales with rule count and is an operator-controlled admin path.

L-8 Unchecked Return

Ignoring _grantRole return in constructor is acceptable; no exploitable path is introduced, and constructor semantics do not depend on that boolean.

Conclusion

All Aderyn findings are either design tradeoffs or static-analysis style heuristics. No code changes are required based on this report.
