Aleksandar Vidakovic commented on FINERACT-2485:
------------------------------------------------
I'm taking this one over, because this is becoming a blocker for 2 other GSoC
projects related to new command processing. We have to have feature parity with
the current (legacy) implementation before we can merge more migrated
packages/modules.

> *Goal:* Standardize idempotency enforcement to prevent replay attacks in core
> financial modules. *Implementation Strategy (Addressing James Dailey's
> feedback):*
> # *Opt-In Architecture:* New logic will be behind a Global Configuration
> flag. Default remains legacy behavior to ensure 100% backward compatibility.
> # *Phased Approach:* Audit existing {{m_portfolio_command_source}} usage and
> bridge gaps in the Savings module first.
> # *Testing:* Implementation of integration tests simulating network
> failures/retries.
