MarketNow is clarifying its security architecture in response to community feedback, specifically addressing concerns about its L1.9 prompt injection screener and L3 runtime interceptor. The L1.9 layer, now renamed "Prompt Injection Screening," uses regex rules to identify potential threats but lacks measured false positive rates. The L3 interceptor acts as a deterministic fail-closed veto, executing before each tool call to block malicious actions, complementing periodic re-attestation checks. MarketNow is also implementing a signed key registry with a `ca_key_id` field to detect key rotations and ensure the integrity of security attestations. AI
IMPACT Clarifies security mechanisms for AI tools, potentially influencing best practices for prompt injection and runtime protection.
