1. CSP Leaf Node provides API for **End workflow**.
2. The CSP Leaf Node **accepts the command** if :-

    A. Operational state of the CSP Leaf node is **ON/OFF/INIT/STANDBY/ALARM**
    B. CSP Sub-array is responsive.

3. The CSP Leaf Node **rejects the command** if :-

    A. Operational state of CSP Leaf node is **FAULT/UNKNOWN/DISABLE** .
    B. CSP Subarray is not responsive.

4. The following **state requirements** are applied for the **command execution** :-

    A. CSP Subarray is in `'observation state'` **READY** .
    B. CSP Subarray node is :term:`available` .

5. The **command execution** involves below **key operations** :-

    A. The command is then invoked on the CSP Subarray.

        + If CSP Subarray **raises exception** , command failure is reported as **'RESULT_CODE - FAILED'** on Long Running Command Result attribute of the CSP leaf node.
        + If CSP Subarry **accept command** , the TMC CSP leaf node will wait for command completion.

    B. Any active delay publication is logically reset;  sets the **delay model** representation to an **initial value**. subsequent observation phases must regenerate delay content via a new Configure.

6. The CSP leaf node **monitors the progress of command** via the CSP sub-array node **ObsState transitions** and the **long running command results**.

    A. Command is **successful** when the CSP Subarray transitions to **IDLE** ObsState. This is reported as **'RESULT_CODE - OK'** on Long Running Command Result attribute of the TMC CSP Subarray leaf node.
    B. Command **failure is reported** in any of the below cases as **'RESULT_CODE - FAILED'** on Long Running Command Result attribute of the TMC CSP Subarray leaf node.

        + The CSP Subarray reports **'RESULT_CODE - FAILED'** on its Long Running Command Result attribute
        + The **command times out** if CSP Subarray does not transition to **IDLE** within the timeout period specified by `CommandTimeOutDefault` property specified in helm chart of the CSP Leaf Node .
