CallWall is a local policy firewall for coding agents. It sits between Claude Code / Codex and every tool call — observe or enforce — so agents can ship code without exfiltrating secrets, touching protected paths, or going off-intent. Hard rules first, semantic judgment second, human approve/deny when it matters. One dashboard. Fail closed.
