**Bernstein 3.4.1 Released: Exciting Features Boost Developer Productivity**

**Introduction**
The latest update to Bernstein, version 3.4.1, arrives with a suite of enhancements aimed at tightening security while streamlining workflows for developers who rely on command‑line coding agents. By extending support to over forty agents—including Claude Code, Codex, and Gemini CLI—the release positions Bernstein as a versatile orchestrator that satisfies both engineering speed and compliance rigor.

**Key Developments**
Version 3.4.1 introduces four core capabilities that directly address common pain points in automated code generation:

1. **HMAC‑chained audit log** – Every action taken by an agent is cryptographically linked to the previous entry, creating an immutable trail that can be verified without exposing underlying data.
2. **Signed agent cards** – Each agent now carries a digitally signed manifest detailing its permissions, version, and provenance, allowing policy engines to approve or reject execution in real time.
3. **Per‑artefact lineage** – Outputs such as generated files, patches, or configuration snippets are tagged with a lineage identifier that traces back to the originating prompt, model, and execution environment.
4. **Air‑gap deployment option** – Organizations operating in isolated networks can run Bernstein entirely offline, with all verification keys stored locally, eliminating reliance on external attestation services.

These features are delivered through a lightweight CLI wrapper that requires no changes to existing agent invocations, preserving the familiar developer experience while adding a compliance layer that auditors can inspect without disrupting
