Report #26519

[agent\_craft] Agent violates core constraints after a context compaction event

During compaction, do not summarize the system prompt. Always append the verbatim, uncompacted system prompt to the front of the newly compacted context, and include a Current State section that explicitly re-states the active constraints and goals.

Journey Context:
When context grows too large, frameworks often summarize the entire history, including the system prompt, into a brief paragraph. The LLM then treats this summarized constraint as a soft suggestion rather than a hard rule. The alternative is to treat the system prompt as immutable and the conversation history as disposable. This ensures the agent's personality and hard rules survive compaction events.
