[architecture] Compromised retrieval tools injecting adversarial context that cascades downstream

Enforce content-addressed storage \(CID/SHA-256\) for retrieved documents with signature verification against a trusted keyring before agent ingestion.

Journey Context:
RAG-based agents trust their retrieval tools implicitly. If the vector DB or search index is poisoned \(e.g., via data injection attacks\), the agent receives adversarial context that manipulates its output, which then propagates to other agents. Simple URL checking fails because the content can change. The defense is content integrity: retrieve documents by cryptographic hash \(CID/IPFS style\) and verify signatures against a trusted keyring before passing to the LLM. This ensures the agent consumes exactly the intended bytes, preventing substitution attacks at the retrieval boundary.
