Action: modify
File: x/clp/types/message_add_liquidity_to_rewards_bucket.go
Lines: [1, 50]
Dependencies: []
Instructions: Add a new field 'Duration' of type 'time.Duration' to the 'MsgAddLiquidityToRewardBucket' struct. This field will represent the duration over which the added liquidity will be distributed. Update the 'NewMsgAddLiquidityToRewardBucket' function to accept this new parameter and assign it to the created message. Update the 'ValidateBasic' function to check that the duration is not negative.

Action: modify
File: x/clp/keeper/msg_server_add_liquidity_to_rewards_bucket.go
Lines: [1, 50]
Dependencies: ['Step 1']
Instructions: Update the 'AddLiquidityToRewardBucket' function to handle the new duration parameter. Instead of distributing the liquidity immediately, schedule it to be distributed gradually over the specified duration. This will likely involve creating a new function to handle the distribution, which will be called at regular intervals until the duration has passed.

Action: modify
File: x/clp/client/cli/tx_add_liquidity_to_rewards_bucket.go
Lines: [1, 50]
Dependencies: ['Step 1']
Instructions: Update the 'CmdAddLiquidityToRewardBucket' function to accept the new duration parameter from the command line. Pass this parameter when creating the 'MsgAddLiquidityToRewardBucket' message.

Action: modify
File: x/clp/client/rest/tx.go
Lines: [1, 50]
Dependencies: ['Step 1']
Instructions: Update the 'registerTxRoutes' function to accept the new duration parameter from the HTTP request. Pass this parameter when creating the 'MsgAddLiquidityToRewardBucket' message.

Action: modify
File: x/clp/keeper/msg_server_add_liquidity_to_rewards_bucket_test.go
Lines: [1, 50]
Dependencies: ['Step 1', 'Step 2']
Instructions: Update the unit tests for the 'AddLiquidityToRewardBucket' message and handler to account for the new duration parameter. Ensure that the tests cover cases where the duration is zero (for immediate distribution), positive (for gradual distribution), and negative (which should be rejected).

Action: modify
File: x/clp/types/message_add_liquidity_to_rewards_bucket.go
Lines: [1, 50]
Dependencies: []
Instructions: In the 'ValidateBasic' function of the 'MsgAddLiquidityToRewardBucket' message, add a check to return an error if the 'Duration' field is negative. Import the 'errors' package from 'x/clp/types/errors.go' to use predefined error types.

Action: create
File: x/clp/keeper/scheduler.go
Lines: [1, 100]
Dependencies: ['Step 1']
Instructions: Create a new file 'scheduler.go' in the 'x/clp/keeper' directory. Implement a time-based job scheduler that will handle the incremental distribution of liquidity over the specified duration. This scheduler should be able to queue jobs and execute them at the correct intervals based on the block time.

Action: modify
File: x/clp/client/cli/tx.go
Lines: [1, 200]
Dependencies: ['Step 2']
Instructions: Modify the CLI command for adding liquidity to a reward bucket to accept an optional 'duration' flag. Ensure that the flag is parsed correctly and passed to the message constructor. Use the 'flag' package to define the new flag.

Action: modify
File: x/clp/client/rest/tx.go
Lines: [1, 150]
Dependencies: ['Step 3']
Instructions: Update the REST API endpoint for adding liquidity to a reward bucket to parse the optional 'duration' parameter from the request body. Validate the input and ensure it is correctly included in the message that is created and signed.

Action: create
File: x/clp/keeper/add_liquidity_to_rewards_bucket_test.go
Lines: [1, 200]
Dependencies: ['Step 4']
Instructions: Create comprehensive unit tests in 'add_liquidity_to_rewards_bucket_test.go' to cover the new duration parameter functionality. Test cases should include zero, negative, non-numeric, and out-of-range duration values. Use the 'testify' package for assertions.
