[frontier] When summarizing old conversation turns to manage context, agent loses constraint-relevant content and drifts

Implement two-tier context management: \(1\) constraint-relevant exchanges are NEVER summarized, only trimmed of tangential detail; \(2\) all other content is aggressively summarized. Tag or flag constraint-relevant turns during the conversation for preservation.

Journey Context:
Standard context compression treats all turns equally — summarize old ones, keep recent ones. But this is exactly wrong for constraint preservation: constraint-relevant exchanges \(where the agent was told or reminded of a rule\) are often early in the conversation and get compressed first, while recent tangential content is preserved at full fidelity. The frontier pattern is 'asymmetric compression' — constraint-relevant content gets special preservation. Teams implement this by either tagging turns as constraint-relevant during conversation or extracting constraint statements into a separate 'constraint buffer' that is always included at full fidelity. Tradeoff: reduces effective context for task-relevant content. But constraint violations are typically more costly than lost task detail, especially in production systems.
