Summary

  • Introduce the CASTS operator under geaflow-ai/src/operator/casts with a complete Python package layout (core models/config/schema/gremlin state, strategy cache, data sources, services, simulation engine, utils).
  • Add LLM‑driven reasoning flow: canonical signature storage with abstract matching, simplePath cycle prevention, LLM‑based path evaluation, and starting‑node type recommendations.
  • Provide a full test suite for lifecycle, state machine, signatures, simplePath, starting node selection, and threshold calculation, plus package config and local tooling.

…ality control

Add native Gremlin simplePath() support to prevent pathological cycles in graph traversals. The implementation uses LLM-guided decision-making and AIMD confidence penalties rather than hard-coded restrictions, staying true to the system's learning philosophy.

Key changes:
- Add simplePath() step to Gremlin state machine for V, E, and P states
- Implement per-request path history tracking in TraversalExecutor
- Add cycle detection with configurable threshold and penalty modes
- Enhance LLM Oracle prompts to recommend simplePath() for exploration goals
- Add recent decision history context to improve LLM decision quality
- Update configuration with CYCLE_PENALTY and CYCLE_DETECTION_THRESHOLD settings
- Document design rationale and rejected alternatives in architecture.md
- Add test case for simple path traversal validation
…ulations

- Updated MetricsCollector to use Optional types for match_type, parent_node, parent_step_index, edge_label, sku_id, and decision parameters.
- Enhanced EVALUATOR documentation to clarify evaluation phases and scoring mechanisms, including coverage rewards and penalties for cache misses.
- Modified test cases in test_execution_lifecycle.py to align with new metrics structure and added tests for simple path execution.
- Improved test coverage in test_gremlin_step_state_machine.py and test_lifecycle_integration.py to validate state transitions and integration with Gremlin state machine.
- Refined threshold calculation tests to ensure monotonicity and boundary conditions.
- Added dynamic execution environment constraints in documentation to clarify step legality in relation to current state and schema.
