Bellwether: research agent with a human in the loop

A research agent that drafts a daily briefing from millions of ingested items, with a human approving every issue before it publishes.

• Laravel app plus a Python LangGraph drafting service
• Research, write, critic and prose-check steps with bounded rewrite loops
• Postgres checkpoints so a killed run resumes where it stopped; LangSmith traces
• Runs on a cost-capped model tier because the economics were designed first
