Field notes
htmlark keeps revisions under a stable key rather than generating a separate dashboard for each agent output. Its example history includes a first submission, a restored revision, and a dirty version that remains stored but cannot execute. Preview runs on loopback at 127.0.0.1:7420, inside a CSP sandbox with network access disabled; the page also documents CLI, skill, and MCP entry points.
