[frontier] Original system instructions get diluted as conversation context grows toward limits

Implement Sacred Context Blocks: explicitly partition your context into 'sacred' instruction blocks that must survive any summarization, truncation, or context management operation, and 'profane' conversation history that can be compressed or dropped. Mark sacred blocks with clear delimiters and include a meta-instruction that no context management operation may modify or summarize the sacred block.

Journey Context:
When context approaches limits, something has to give. Most summarization strategies treat all context as equally compressible, which means original instructions get summarized along with conversation history. A 500-word system prompt becomes a 50-word summary, losing critical nuance. The emerging pattern in 2025-2026 is to explicitly designate instruction blocks as non-negotiable. This requires building context management that understands the partition — either through application-level logic \(your code never includes sacred blocks in summarization calls\) or through explicit marking that the model itself respects. The key insight: if your context management doesn't know which parts of the context are sacred, it will inevitably compress the wrong things.
