Report #59433

[synthesis] Agent solution violates original hard constraints after 100\+ steps despite each individual step appearing valid

Freeze original constraints as immutable embeddings or exact strings that must be explicitly re-consulted and matched against at each decision node using string matching, not just paraphrased in the prompt

Journey Context:
This is distinct from general context loss; it's concept drift where the meaning of terms shifts \(e.g., 'secure' gradually redefined to mean 'encrypted' rather than 'authenticated'\). Standard context management preserves the text but the model's interpretation drifts. Paraphrasing for context compression accelerates this. The fix requires 'semantic anchoring' - literal string matching against original constraints to prevent drift.
