[synthesis] Agent enters infinite loop alternating between two code states, each 'fixing' the other but never converging

Implement a 'state fingerprint registry' that hashes the code state after each edit; if a hash repeats, halt and escalate to human review rather than allowing another iteration.

Journey Context:
Without an external oracle \(test execution\), agents rely on their own reasoning to validate fixes. This leads to oscillation: the agent identifies 'Issue A', fixes it, then identifies 'Issue B' \(which is actually the undoing of the first fix\), fixes that, returning to State A. Standard retry limits don't catch this because the error message changes each time. The fingerprint registry detects the cycle by state identity, not error message, breaking the loop before token waste becomes catastrophic. This acknowledges that in oracle-less environments, stability is more valuable than iterative 'improvement.'
