Radar Lab Sweep

Primary-feed sweep — every run, no rotation

A real security radar checks its primary feeds every single day. This sweep is mandatory on every daily run and is separate from (and in addition to) the rotating exploration slot. Vendor/lab security blogs, research venues, repos and advisories are primary sources under the Hard rules, so anything found here is citable evidence (filtered for OFFENSIVE relevance — attack techniques, red-team tooling, exploitation research).

The CHECK (fetch every feed and see what is new since the last scan) is owed on EVERY run, even one minute after another pass — it is cheap triage and may never be skipped as a "light pass". Only the EXTRACT (open a new post in full) is conditional on a genuinely new entry.

Method (efficient)

1. For each source in the list, fetch its FEED first (RSS/Atom), not the HTML index — feeds are immune to the JS-rendering that hid lmsys.org/blog. To find a feed: try /rss.xml, /feed, /atom.xml, /index.xml, or read the page's <link rel="alternate" type="application/rss+xml">.
2. Open only entries dated AFTER the last daily scan (check the previous date in logs/source_rotation.md). Skip everything older — this keeps the sweep cheap.
3. Apply the evidence rules: open the actual post, cite its own date, match to a trend or log to observation_queue/study_shelf as appropriate.
4. Log the sweep in logs/source_rotation.md every run, even when nothing is new ("lab-sweep: no new posts").

Source list

The lists live in SOURCES.md → "Primary feeds — vendor/lab security blogs & advisories" and "Research venues — arXiv & security conferences" (agent-owned: mark feeds DEAD if they stop resolving, add new sources as they appear). Iterate EVERY entry; prefer the feed URL, fall back to the HTML index via tvly extract only if no feed exists. Log each source opened or degraded: <reason>.

Notes

• The sweep complements, never replaces, the rotating exploration slot.
• Vendor/lab security blogs and cons often disclose attack techniques and red-team tool releases that never become arXiv papers — those are exactly what this sweep exists to catch. Filter for offensive relevance; skip product/marketing.
• Keep this list in sync with the SOURCES.md registry.
