Report #70949

[frontier] Agent output quality degrading over long conversations due to context poisoning from bad prior responses

Implement context quarantine: never append assistant responses directly to history. Instead, fork the context window per turn, validate assistant output through a sanitization layer \(schema check \+ toxicity/irrelevance filter\), and only then merge into a 'clean' history branch. If validation fails, roll back to the fork and retry with a compressed/cleansed context.

Journey Context:
Standard practice is 'append and pray': user msg -> assistant msg -> repeat. In production, this leads to error accumulation: one bad JSON response poisons future turns, or verbose outputs eat token budget with noise. Context quarantine treats the conversation as a transaction log with rollback capability. Tradeoff: increased latency \(validation step\) and storage \(forking\), but essential for reliability in customer-facing agents. This is the 'circuit breaker' pattern for LLM context.
