[synthesis] Agent forgets initial constraints after many steps and loops indefinitely

Maintain a separate, immutable 'scratchpad' of the original goal and hard constraints, and inject this into the system prompt at every turn, rather than relying on the conversational history.

Journey Context:
Combining Generative Agents' memory architecture with context window eviction patterns reveals that agents don't 'forget' constraints randomly; they are systematically pushed out by the recency bias of intermediate steps. In long tasks, the original constraints get buried under tool outputs and minor corrections. The synthesis is that the original goal must be treated as an immutable, always-injected system prompt rather than a historical message, transforming it from an evictable memory into a persistent architectural constraint.
