Report #37783

[frontier] RAG retrieval from previous sessions imports corrupted instructions or drifted interpretations into new sessions

Implement 'Memory Quarantine' - new sessions start with verified canonical instructions only; historical memory is suggestion-only and cannot override base constraints

Journey Context:
Teams assumed persistent memory improved consistency; actually amplified drift across sessions like a game of telephone. Historical embeddings captured drifted states and re-injected them. Memory quarantine treats persistent memory as untrusted suggestions requiring verification against canonical base prompt. Critical: base prompt must be immutable hash, not just text.
