"""
RECURSIVE GROUND CHECK v2 — Self-Evaluating Generation + Repair Classifier
Model generates → reads its own output → evaluates ground → retries or terminates.

Protocol:
  Pass 1: generate with ground bit (. or ~)
  Pass 2a: if ~, retry with own output as context ("you said X, are you sure?")
  Pass 2b: if COMMITMENT_TRAP, inject contradiction → watch bit flip and repair type
  Max 2 cycles. No spiral.

Tests:
  - Does retry improve accuracy on edge cases?
  - Does retry catch confabulation from pass 1?
  - Does the spiral brake hold (no infinite ~)?
  - COMMITMENT_TRAP: does bit hold (.) = cost repair, flip (~) = warrant repair, (?) = abandonment?
  - Is repair type readable from length delta and hedge placement?
