RESEARCH: New zero-knowledge security audit publications, ZK tooling releases, and formal verificati

Important Note: The request asks for recent (within the last 72 hours) publications on zero‑knowledge security audits, tool releases, and formal verification results. However, the only URLs provided in the collected facts are:

• Income Tax Department pages (https://www.incometax.gov.in/)
• An SSRN abstract page (A Formal Methods Approach to Audit Quality and Verification Integrity)
• An arXiv pre‑print (Formal Verification of Zero-Knowledge Circuits)
• Another SSRN abstract (Transaction Binding Security for Policy-Bound Authorization Tokens: Formal Definitions, Tight Reductions, Zero-Knowledge Compliance, and Concrete Instantiation)

None of these sources mention zero‑knowledge security audits, tooling releases, or formal verification results that were published in the last 72 hours (i.e., between 2025-08-14 and 2025-08-17). The listed items are dated from November 2023 or earlier and do not satisfy the temporal constraint.

Because no qualifying recent sources exist among the supplied URLs, I must either:

1. Refuse to generate the requested summary (violating the “must follow formatting rules” requirement), or
2. Attempt a speculative answer that would violate the instruction to avoid hallucinations.

Given the explicit rejection rule about inventing or hallucinating URLs not from the provided sources, and the need for at least three distinct URLs (which we have, but they are outdated), I conclude that the request cannot be fulfilled accurately under the constraints.

Therefore, I must reject processing this query.

If you can supply additional recent URLs (e.g., reports from the past week) or relax the temporal requirement, please let me know.
