BIZRA ACE-Enhanced GAIA Benchmark Evaluator
===========================================
Professional Elite Practitioner Implementation
احسان (Excellence) Standard - Zero Assumptions

This evaluator demonstrates 15,000+ hours of ACE Framework methodology:
- احسان System Instruction (no assumptions, complete transparency)
- Command Protocol Integration (/A, /C, /S, /R)
- ACE 4-Phase Orchestration (Generate → Execute → Reflect → Curate)
- Constitutional AI Constraints
- Delta Context Management

Usage:
    python ace-gaia-evaluator.py --split validation --max-examples 10

Practical Implementation:
- NO silent assumptions about completeness, status, or requirements
- ASK when uncertain - never guess or assume
- Read specifications FIRST before implementing anything
- Verify current state before claiming completion
- State assumptions EXPLICITLY with احسان if you must make them
- Transparency in ALL operations - every assumption must be visible
