Welcome to the **AI Policy and News Dashboard**, an automated platform tracking technology policy developments, legislative movement, and media coverage.

The portal will auto-populate with newly scanned data every 1 hour.

This portal's information is divided into two tabs:
* **Radar (Upcoming & Today's News):** Forward-looking policy-relevant data when it is available and daily news updates.
* **Archive (Past):** Historical data on past media coverage, actions from executive agencies and the White House, and legislation from the current Congress. 
* **How to Filter:** Use the **Controls in the left sidebar** to filter by specific data categories or use the search bar below.

### Category Legend
To help you scan the chronological timeline quickly, entries are color-coded:
* 🟣 **Legislation** (Bills, Resolutions)
* 🟢 **Federal / Exec Action** (Agencies, White House)
* 🔵 **News / Media** (Press Coverage)
* 🟠 **Schedule / Hearing** (Committee Meetings, Markups)
* 📣 **Legislative Office Press Release** (Lawmaker Announcements)

To generate a high-level summary of the most recent data entries, click the **"Generate Briefing"** button below.

### Notes for Users
1. **Verify AI Outputs:** This portal leverages summaries generated by language models. All intelligence should be verified using the links to original sources.
2. **Work in Progress:** This is an alpha version. Improvements in coverage and AI logic will be made regularly.

    * **Filtering:** Articles and bills are strictly filtered against a hardcoded tech-policy dictionary before the AI reads them.
    * **Data Retention:** News expires from the UI after 30 days, Schedules after 60 days. Legislation is retained for the duration of the current Congress.
