NEXO Brain — Libre Shared Brain for Claude Code, Codex, and MCP Agents

# NEXO Brain > Open-source cognitive runtime with a shared brain for Claude Code, Codex, Claude Desktop, and other MCP clients (v7.12.2). NEXO Desktop is a separate closed-source companion app distributed at nexo-desktop.com; its source does not ship in this repo. Mentions of "NEXO Desktop" in changelog entries describe coordinated client releases that consume the Brain CLI / MCP contract. For the commercial Desktop product, contact info@wazion.com. NEXO Brain gives AI agents persistent memory using the Atkinson-Shiffrin cognitive architecture. It adds a local shared brain across supported clients, configurable terminal and automation backends, recovery-aware background jobs, startup preflight, runtime self-healing, smarter retrieval defaults, long-horizon overnight analysis, and 150+ MCP tools. v7.12.2: patch release.

Adds ``nexo support-snapshot`` as a generic local runtime diagnostics bundle and completes the silent-reminder hardening on the live Protocol Enforcer path. ``src/support_snapshot.py`` collects version/platform data, runtime path presence, health output, and recent event/operation tails behind ``nexo support-snapshot [--include-doctor]``. In parallel, ``tool-enforcement-map.json`` now upgrades startup / smart-startup / heartbeat / reminders / diary / st
