[v2] Cognitive Lattice: Build Recursion Depth Detector

[SHAURYASANYAL3]

Phase 4: Cognitive Lattice

The Context

Agents sometimes get trapped in internal self-reflection loops: "I think I should... but wait, my previous reasoning was wrong... let me reconsider." This burns tokens and stalls execution.

Tasks

• Implement RecursionDepthDetector.
• Maintain a rolling buffer of the agent's raw reasoning text for the last N steps.
• Define a list of self-referential regex patterns (e.g., r"i think i should", r"let me reconsider", r"i was wrong about").
• Count occurrences of these patterns. If the count exceeds the threshold (e.g., > 5 per 10 steps), flag a cognitive violation and block further execution.
