[synthesis] Agent violates original constraints after several execution steps

Maintain a 'Constitutional Context' message that is pinned to the first position in the context window and regenerated every N tokens to prevent it from being pushed out by execution details; never rely on the plan being 'understood' from earlier turns.

Journey Context:
When an agent creates a plan \('Step 1: Read config, Step 2: Edit file X, Step 3: Do not touch file Y'\), the initial plan message is semantically rich. As execution proceeds, the context fills with API response JSON, file contents, and error logs. The 'do not touch file Y' instruction, being at the top, gets evicted from the context window first \(FIFO eviction in some implementations, or simply attention dilution\). By step 5, the agent has no memory of the constraint and edits file Y. Common fixes like 'summarize the conversation' fail because the summary is generated later and lacks the original imperative tone. The only robust solution is to treat critical constraints as a separate memory stream that is explicitly re-injected or pinned, similar to how system prompts are handled. This is distinct from standard 'memory' because it requires protection from eviction, not just retrieval.
