[synthesis] Agent violates a core constraint in later steps because context window summarization dropped the immutable constraint

Maintain a separate, unsummarized scratchpad or system prompt section for immutable environmental constraints that persists outside the rolling context window summarization logic.

Journey Context:
To handle long tasks, agents summarize older steps. Summarization is lossy; it preserves the actions taken but drops the constraints that governed them \(e.g., 'Use Python 3.8 syntax'\). In later steps, the agent, operating on the summarized context, uses Python 3.10 syntax because the constraint is gone. Developers try to fix this by increasing context size, which just delays the inevitable. The synthesis is that summarization algorithms don't distinguish between transient state and immutable constraints. The fix is architectural: a two-tier memory system where constraints are exempt from the summarization pipeline.
