refactor: move brother_node development artifact to dev/test-nodes subdirectory
Development Artifact Cleanup: ✅ BROTHER_NODE REORGANIZATION: Moved development test node to appropriate location - dev/test-nodes/brother_node/: Moved from root directory for better organization - Contains development configuration, test logs, and test chain data - No impact on production systems - purely development/testing artifact ✅ DEVELOPMENT ARTIFACTS IDENTIFIED: - Chain ID: aitbc-brother-chain (test/development chain) - Ports: 8010 (P2P) and 8011 (RPC) - different from production - Environment: .env file with test configuration - Logs: rpc.log and node.log from development testing session (March 15, 2026) ✅ ROOT DIRECTORY CLEANUP: Removed development clutter from production directory - brother_node/ moved to dev/test-nodes/brother_node/ - Root directory now contains only production-ready components - Development artifacts properly organized in dev/ subdirectory DIRECTORY STRUCTURE IMPROVEMENT: 📁 dev/test-nodes/: Development and testing node configurations 🏗️ Root Directory: Clean production structure with only essential components 🧪 Development Isolation: Test environments separated from production BENEFITS: ✅ Clean Production Directory: No development artifacts in root ✅ Better Organization: Development nodes grouped in dev/ subdirectory ✅ Clear Separation: Production vs development environments clearly distinguished ✅ Maintainability: Easier to identify and manage development components RESULT: Successfully moved brother_node development artifact to dev/test-nodes/ subdirectory, cleaning up the root directory while preserving development testing environment for future use.

|

* This is mostly useful when the delegate is a contract that implements its own rules for voting. These delegate-contracts

* can cast fractional votes according to the preferences of multiple entities delegating their voting power.

*
|

* Some example use cases include:

* distributed amongst the 3 options (Against, For, Abstain) by specifying a fractional `support`.
|
||||
*
|
||||
* This counting module supports two vote casting modes: nominal and fractional.
|
||||
*
|
||||
* - Nominal: A nominal vote is cast by setting `support` to one of the 3 bravo options (Against, For, Abstain).
|
||||
* - Fractional: A fractional vote is cast by setting `support` to `type(uint8).max` (255).
|
||||
*
|
||||
* Casting a nominal vote requires `params` to be empty and consumes the delegate's full remaining weight on the
|
||||
* proposal for the specified `support` option. This is similar to the {GovernorCountingSimple} module and follows
|
||||
* the `VoteType` enum from Governor Bravo. As a consequence, no vote weight remains unspent so no further voting
|
||||
* is possible (for this `proposalId` and this `account`).
|
||||
*
|
||||
* Casting a fractional vote consumes a fraction of the delegate's remaining weight on the proposal according to the
|
||||
* weights the delegate assigns to each support option (Against, For, Abstain respectively). The sum total of the
|
||||
* three decoded vote weights _must_ be less than or equal to the delegate's remaining weight on the proposal (i.e.
|
||||
* their checkpointed total weight minus votes already cast on the proposal). This format can be produced using:
|
||||
*
|
||||
* `abi.encodePacked(uint128(againstVotes), uint128(forVotes), uint128(abstainVotes))`
|
||||
*
|
||||
* NOTE: Consider that fractional voting restricts the number of casted votes (in each category) to 128 bits.
|
||||
* Depending on how many decimals the underlying token has, a single voter may require to split their vote into
|
||||
* multiple vote operations. For precision higher than ~30 decimals, large token holders may require a
|
||||
* potentially large number of calls to cast all their votes. The voter has the possibility to cast all the
|
||||
* remaining votes in a single operation using the traditional "bravo" vote.

/**
|
||||
* @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.
|
||||
*
|
||||
* NOTE: `AccessManager` does not support scheduling more than one operation with the same target and calldata at
|
||||
* the same time. See {AccessManager-schedule} for a workaround.
