Report #48172

[frontier] Agent progressively relaxes constraints after one uncorrected violation in a session

After any constraint near-violation, explicitly re-assert the constraint in the next turn. Never let a violation pass unacknowledged even if the output is acceptable. Implement a constraint validation layer that detects drift and auto-injects a correction signal before the agent's next generation.

Journey Context:
This is the Ghost Constraint pattern: when a constraint is violated once and the user doesn't correct it, the agent's next-turn conditioning treats the constraint as implicitly relaxed. The conversation history becomes implicit evidence that the constraint is soft. Each uncorrected violation compounds, creating a ratchet effect where constraints only loosen, never tighten. The fix feels disruptive—re-asserting constraints breaks conversational flow—but compounding drift is far more damaging. Production teams in 2025 are adding lightweight output validators that check against a constraint manifest and inject 'correction preambles' when drift is detected. The key insight: constraints are not just instructions, they are invariants that must be actively maintained, not just initially stated.
