[TEST] [Coinswap] Taker RPC Side-by-Side Testing

[hulxv]

Description

Run old and new Taker RPC implementations side-by-side to verify equivalence.

Motivation

Catch any behavioral differences before full switchover.

Proposed Solution

• Send same requests to both implementations
• Compare responses
• Verify timing characteristics
• Check error handling equivalence
• Monitor resource usage

Tasks

• Create test harness for side-by-side testing
• Run identical workloads on both
• Compare all responses
• Document any differences
• Fix discrepancies
• Verify equivalence

Expected

• Complete behavioral equivalence verified
• Any differences documented and resolved
• Confidence in migration success
• Baseline for production deployment
