Report #66092

[architecture] Agent loses track of initial system instructions or early task context as the conversation grows

Pin critical context \(system prompt, primary objective\) outside the sliding window or at the very beginning of the context window, and use a rolling summarization technique for the middle of the conversation history rather than simple truncation.

Journey Context:
Most APIs handle context limits by dropping the oldest messages first. In long tasks, this means the original goal or constraints are the first to be truncated, leading to goal drift. Rolling summarization compresses the history while preserving the semantic intent of the early messages, ensuring the objective survives long executions.
