Report #100382

[architecture] Multi-agent chains lack an immutable audit trail of decisions and tool calls

Log every inter-agent message, tool invocation, model response, and validation result in an append-only, tamper-evident trace. Include agent identity, timestamp, prompt version, and input hashes.

Journey Context:
Without a trace, debugging a multi-agent failure is guesswork and forensic investigation is impossible. The trace must be append-only and structured, not just raw console logs, because agents may themselves attempt to manipulate history. Include enough context to replay the exact reasoning path without exposing secrets. The tradeoff is storage and potential log-injection risks if the trace itself becomes an attack surface, so protect it with the same rigor as a database write-ahead log. This is what makes multi-agent systems auditable rather than opaque.
