The AccessManager contract is a role-based access control system that manages permissions for different roles and accounts. It allows granting and revoking roles, setting execution delays, and checking authorization for function calls. It also supports scheduling and executing restricted operations with specified delays.

     * empty `calldata`, sharing the `0x00000000` selector permissions as well.
     * * For any other selector, if the restricted function is set on an upgradeable contract, an upgrade may remove
     * the restricted function and replace it with a new method whose selector replaces the last one, keeping the
     * previous permissions.

/**
 * @dev This module connects a {Governor} instance to an {AccessManager} instance, allowing the governor to make calls
 * that are delay-restricted by the manager using the normal {queue} workflow. An optional base delay is applied to
 * operations that are not delayed externally by the manager. Execution of a proposal will be delayed as much as
 * necessary to meet the required delays of all of its operations.
 *
 * This extension allows the governor to hold and use its own assets and permissions, unlike {GovernorTimelockControl}
 * and {GovernorTimelockCompound}, where the timelock is a separate contract that must be the one to hold assets and
 * permissions. Operations that are delay-restricted by the manager, however, will be executed through the
 * {AccessManager-execute} function.
 *
 * ==== Security Considerations
 *
 * Some operations may be cancelable in the `AccessManager` by the admin or a set of guardians, depending on the
 * restricted function being invoked. Since proposals are atomic, the cancellation by a guardian of a single operation
 * in a proposal will cause all of the proposal to become unable to execute. Consider proposing cancellable operations
 * separately.
 *
 * By default, function calls will be routed through the associated `AccessManager` whenever it claims the target
 * function to be restricted by it. However, admins may configure the manager to make that claim for functions that a
 * governor would want to call directly (e.g., token transfers) in an attempt to deny it access to those functions. To
 * mitigate this attack vector, the governor is able to ignore the restrictions claimed by the `AccessManager` using
 * {setAccessManagerIgnored}. While permanent denial of service is mitigated, temporary DoS may still be technically
 * possible. All of the governor's own functions (e.g., {setBaseDelaySeconds}) ignore the `AccessManager` by default.

/**
 * @dev A forwarder compatible with ERC2771 contracts. See {ERC2771Context}.
 *
 * This forwarder operates on forward requests that include:
 *
 * * `from`: An address to operate on behalf of. It is required to be equal to the request signer.
 * * `to`: The address that should be called.
 * * `value`: The amount of native token to attach with the requested call.
 * * `gas`: The amount of gas limit that will be forwarded with the requested call.
 * * `nonce`: A unique transaction ordering identifier to avoid replayability and request invalidation.
 * * `deadline`: A timestamp after which the request is not executable anymore.
 * * `data`: Encoded `msg.data` to send with the requested call.
 *
 * Relayers are able to submit batches if they are processing a high volume of requests. With high
 * throughput, relayers may run into limitations of the chain such as limits on the number of
 * transactions in the mempool. In these cases the recommendation is to distribute the load among
 * multiple accounts.
 *
 * NOTE: Batching requests includes an optional refund for unused `msg.value` that is achieved by
 * performing a call with empty calldata. While this is within the bounds of ERC-2771 compliance,
 * if the refund receiver happens to consider the forwarder a trusted forwarder, it MUST properly
 * handle `msg.data.length == 0`. `ERC2771Context` in OpenZeppelin Contracts versions prior to 4.9.3
 * do not handle this properly.
 *
 * ==== Security Considerations
 *
 * If a relayer submits a forward request, it should be willing to pay up to 100% of the gas amount
 * specified in the request. This contract does not implement any kind of retribution for this gas,
 * and it is assumed that there is an out of band incentive for relayers to pay for execution on
 * behalf of signers. Often, the relayer is operated by a project that will consider it a user
 * acquisition cost.
 *
 * By offering to pay for gas, relayers are at risk of having that gas used by an attacker toward
 * some other purpose that is not aligned with the expected out of band incentives. If you operate a
 * relayer, consider whitelisting target contracts and function selectors. When relaying ERC-721 or
 * ERC-1155 transfers specifically, consider rejecting the use of the `data` field, since it can be
 * used to execute arbitrary code.
