[frontier] Effective system prompt drifts due to context window compression without detection

Implement Semantic Versioning for Prompts: embed semantic version identifiers \(e.g., [email protected]\) and content-addressable hashes \(SHA-256\) in conversation metadata at each checkpoint, with automated diffing against canonical source to detect semantic mutation

Journey Context:
As contexts grow, compression algorithms \(explicit summarization or implicit attention decay\) mutate the effective system prompt. The 'effective constitution' at turn 100 is a lossy compression of the original plus accumulated conversation bias. Traditional version control applies to static prompts, but dynamic conversations require content-addressable storage where the effective prompt hash is verified against a canonical Merkle tree root. This enables precise causality tracking: when behavior drifts, the hash mismatch identifies exactly which compression step introduced semantic mutation, triggering targeted recovery rather than full reset.
