Report #71316

[synthesis] Agent follows user instructions but ignores system constraints mid-session

Inject a hash or checksum of critical system instructions at the end of the context window; monitor for its presence and accurate recall in the agent's planning step.

Journey Context:
Teams monitor for exceptions, but LLMs silently drop the earliest tokens \(usually system prompts\) when hitting context limits. The agent keeps working, producing syntactically valid output that violates safety or policy rules. Checking token count isn't enough; you must verify the agent's attention to the core directive. Checksumming the instruction forces a verifiable anchor that bridges context management and prompt adherence, revealing silent context truncation before a policy violation occurs.
