One pipeline fire, in full · intel run of 2026-06-14 · sub-agent allocation and telemetry, per-iteration verification verdicts and findings, source-list edits, coverage gaps, bridge invocations — and the run's own verification & coverage notes: what was published, what was dropped at the borderline or judged not relevant (and why), single-source carve-outs, and contradictions. Rendered from runs/2026-06-14/2026-06-14-e1d80e78.md.

Sources changed (this run)
Edits this run made to sources/sources.json · promotions, demotions, new candidates, and fetch-method / category / reliability / url corrections (the run record's sources_changed[]). Paginated; 10 per page.
No source-list edits recorded for this run.
Coverage gaps (this run)
Sources this run's brief needed that returned no usable content via any documented recipe. Bridge-recovered or quiet-day sources do NOT appear here. (Distinct from the independent source-accessibility probe at the foot of this section, which probes all active sources regardless of what any run needed.)

Verification findings · all iterations
Per-iteration finding detail. Each table is one verifier pass · what was flagged, how the main agent remediated it, and the outcome. Walking the tables top-to-bottom shows the verifier's debugging trail across iterations.

Verification & coverage notes
The run record's narrative body, verbatim. This is where the run accounts for its own judgement calls — every borderline drop and judged-not-relevant item with its reason, dedup decisions, single-source items and their carve-outs, contradictions, and per-source coverage gaps — so nothing the run considered disappears silently.
Verification & coverage notesrun record body
2026-06-14-e1d80e78 · Claude Opus 4.8 · 8 entries published
- Items dropped — already covered (PD-8), no material delta: "GreatXML" BitLocker bypass (covered 2026-06-12; still no CVE/patch, no new exploitation); Velvet Ant "Operation Highland" Linux auth-stack backdooring (was the 2026-06-13 deep dive — deep dives are not re-summarised, PD-9); ServiceNow unauthenticated REST endpoint (covered 2026-06-11); University of Nottingham / CVE-2026-35273 ShinyHunters breach (the 455 K-record / multi-campus / ICO-notification facts were already in the 2026-06-12 and 2026-06-13 UPDATEs — a third consecutive update is barred by the long-running-campaign rule; the only new element, Have I Been Pwned indexing, is not material).
- CVEs that did not clear a § 2 inclusion gate: CVE-2026-47210 (vm2 Node.js sandbox escape, CVSS 9.8) — primary disclosure dated 2026-05-29 (GitLab advisory metadata refreshed 06-12), outside the recency window, no in-the-wild exploitation or public PoC confirmed; relevance is to code-evaluation sandboxes rather than internet-exposed services. CVE-2026-12183 (BUK TS-G gas-station automation auth-bypass, CVSS 9.8) — ENISA EUVD flags it exploited with a public PoC, but the only available sources are a per-CVE aggregator page (CIRCL Vulnerability Lookup) and a low-reliability news aggregator; no vendor or national-CERT advisory exists, and the product is a Russian-developed system with negligible Swiss/EU public-sector deployment.
- Items dropped — below the daily relevance bar: INTERPOL Operation Ramz / SniperDz PhaaS takedown (201 arrests, MENA region — significant but indirect CH/EU nexus and no 1–7-day defender action); 23andMe $46.75 M breach-settlement approval (civil-liability closure of the 2023 breach; no defender action); Great Marlow School UK ICT incident (resolved in under 48 h with "no threat identified"; limited operational lesson).
- Single-source items: § 3 APT28 tradecraft evolution rests on the Sekoia TDR report alone — it is primary research (the lab's own analysis), so the attribution and TTP claims are presented as Sekoia's findings; no independent corroboration of the LameHug/BeardShell/FrostArmada specifics was located in-window.
- Contradictions: none material this run.
- Sub-agents: all four (S1–S4) returned within budget; all ran on Claude Sonnet 4.6.
- Coverage gaps: inside-it-ch (Cloudflare Managed Challenge — bridge returned no body; no unique in-window Swiss items beyond those captured elsewhere); sophos-xops (feed 503); group-ib (press-release 503 — INTERPOL/Infosecurity used instead, story covered anyway); databreaches-net (403 — BleepingComputer/TechTimes corroborated the Kyushu story); sec-disclosures-edgar (0 qualifying Item 1.05 8-K filings in window — confirmed absence, not a transport failure); cert-fr-actu (RSS feed stale, returning October 2025 items); prodaft (not fetched within time budget); cnil-fr, edpb, ico-uk (no new in-window notices).
Unmatched action items (migrated)
- Hunt for APT28's current evasion classes (no IOCs required). Alert on cloud-storage beaconing to Koofr/Icedrive/Filen from non-user workstations, outbound traffic to Hugging Face inference endpoints from Windows hosts, MikroTik/TP-Link DNS-setting changes in device logs, and Office documents delivered via Signal Desktop that lack the Mark-of-the-Web (an APT28 Office-lure delivery path). See § 3.
- Audit removable backup-media controls. Verify backup media leaving server rooms is encrypted at rest, asset-tagged and access-logged — the Kyushu Electric loss (10.9 M records, unencrypted SSD) is a NIS2 Article 21(2)(h)-class failure with no remote attacker. See § 1.
