Description

Develop a new communication protocol using FlatBuffers to enable reliable, categorized, and resumable communication between agent modules (FIM, SCA, Inventory) and the server.

Tasks

• Define FlatBuffers schema as described in this comment
• Implement persistence layer
• Implement message creation logic in C++
• Develop module API to accept input from FIM, SCA, and Inventory
• Interface with wazuh-agentd for actual sending of messages
• Handle retries, EndAck, ReqRet, and other protocol flows
• Implement sequence tracking and message categorization

DoD

• FlatBuffers schema reviewed and approved
• Unit and integration tests for all message types
• Simulated flow covering all protocol steps
• Protocol module correctly communicates with wazuh-agentd
• Resilience tested (e.g., server unavailable, interrupted flow)
