[synthesis] Agent silently drops negative constraints during long-context summarization, causing sudden constraint violations without error logs

Pin critical negative constraints \(e.g., 'NEVER delete'\) to the front of the prompt using XML tags like , and validate summaries against a constraint checksum before proceeding

Journey Context:
Single sources document 'Lost in the Middle' position bias or context compression, but none observe that negative constraints \(prohibitions\) are dropped before positive goals during summarization. This happens because compression algorithms prioritize 'actionable' semantic content over 'restrictive' content. The synthesis reveals that this asymmetric loss is systematic: negations have lower semantic density in the model's embedding space and are preferentially pruned. The fix forces critical constraints into a reserved section that bypasses standard summarization heuristics, preventing the asymmetric loss of prohibitions.
