Verification & coverage notes

Quiet 6-hour intraday window (gap from the 2026-07-04T1209Z-intel run). Four research sub-agents (S1–S4, all Sonnet 5) plus one scoped Phase-2 follow-up ran; zero entries published — expected and healthy for an intraday window (PD-7 Intraday class: 0–4 entries, zero is healthy). S2/S3/S4 returned no in-window candidates: every essential home-region / research / incident source was fetched fresh, but the newest content on each predated the 8 h window (typically 2026-07-01…03), and every surfaced lead traced to ground already covered by earlier runs (JadePuffer/Langflow, NetNut PoPa botnet, Avalon/CrownX, PamStealer, Medtronic/ShinyHunters, AdaptHealth, Navient, MedusaLocker/Canton Zürich, SharePoint CVE-2026-45659) or failed PD-6 fake-news scrutiny (unconfirmed leak-site claims against Deutsche Bank / Ferrum AG — no victim confirmation or HIGH-reliability journalism).

• borderline-drop: "Bad Epoll" (CVE-2026-46242, Linux kernel eventpoll use-after-free LPE, CWE-416, CVSS 7.8) — S1's only candidate. Dropped. Fails the vulnerability inclusion gate: local LPE (not pre-auth RCE), no in-the-wild exploitation, not on CISA KEV (confirmed via fetch_source.py cisa-kev), CVSS 7.8 (<9.0), and the upstream fix (commit a6dc643c6931) landed in mainline 2026-04-24 — ~10 weeks out of window. The only in-window event is researcher Jaeyoung Chung's public root-cause write-up + working kernelCTF PoC (~2026-07-01…03), amplified by tech press (The Hacker News, PBX Science, Latest Hacking News); the write-up itself is a GitHub PoC repo, not directly citable as analysis. Org-relevance for a Swiss federal SOC in the next 1–7 days is low — the patch has been available since April, so the action reduces to "confirm the April/May kernel updates are applied," and no public detection signature exists. Newsworthy but below the org-actionability bar (PD-11: relevance over newsworthiness). A scoped follow-up sub-agent recovered proper distro-tracker primaries (Ubuntu/Debian security trackers name the CVE) had inclusion been warranted.
• Infra finding: git.kernel.org commit pages now sit behind an Anubis anti-bot proof-of-work challenge that neither WebFetch nor tools/fetch_source.py url can solve — logged as a fetch_failure and recorded in .claude/memory/source-fetch-blocks.md. Substitute primary for kernel CVEs going forward: distro security trackers (ubuntu.com/security/CVE-…, security-tracker.debian.org), which are citable role: primary and not blocked-URL patterns.
• Candidate source considered, not added: pbxscience.com (produced the only dated timeline separating the April patch from the July PoC release). Declined — general tech blog, moderate reliability, no track record; kept out to preserve source-list quality. Noted for future consideration.
• Coverage gaps: cisa-advisories (403 on bridge — persistent, known); cisa-directives (403 on bridge — persistent, known); cisa-news (403 on bridge); industrialcyber-co (403 direct — recipe may need a bridge fallback); tenable-research (guessed rss path 404 — record lacks a specific rss_url); mozilla-mfsa, projectzero (quiet, no in-window content); sans-newsbites, prodaft (JS-rendered SPA, no server content — recipe gaps); ncsc-ch aktuelle-vorfaelle + OFAC recent-actions (JS-rendered — recipe gaps).
• Essential-coverage: missed=cisa-advisories (403 transport, content covered_anyway via WebSearch fallback — nothing new in-window), cisa-directives (403 transport, covered_anyway via WebSearch fallback). Both are ongoing transport 403s already logged in sources/sources.json; a 403 does not demote.
• Source-health probe (tools/source_health.py, 153 sources): 96 ok, 52 bridge-ok, 2 client-error, 3 bridge-fail. UNSOLVED flags — cisa-advisories/directives/news needs-demote: declined, these are HIGH-value essentials returning 403 (transport block, not death) and the hard rule forbids demoting on a 403. github-advisory needs-bridge (browser UA 403): deferred — a dedicated bridge recipe needs authoring + testing, out of scope for this quiet maintenance run; logged here for a follow-up. state/source_health.json updated; sources/sources.json unchanged (no safe autonomous action this run).
• Wall-clock note: the session was suspended between Phase 2 and Phase 5, so duration_seconds (≈17.8 h) reflects the suspend gap, not compute. Active processing was ≈15 min — all research sub-agents ran 2026-07-04T18:11…18:22Z; the run's window, dedup, and content are correctly anchored to the 2026-07-04T18:09Z fire.
