Scout 5, Research: horizon sweep 2026-11-10T1415Z

Started 2026-11-10T14:19Z, ended 2026-11-10T14:23Z (UTC). Sonnet 5.5 scout. Every claim below is "reported by" the page, read as an abstract or listing summary through WebFetch's small model, which paraphrased abstracts rather than quoting them; I read no full paper text and checked nothing against data. Quotations are therefore short and few.

Method note: robots.txt gate

  • The 7 November scout read arXiv through export.arxiv.org/api/query. The gate now says that host disallows everything ("Disallow: /", decided by "*"). Not fetched: robots.txt. The API is not used again; later sweeps should use arxiv.org/list and arxiv.org/abs, which the gate allows (rules "Allow: /list", "Allow: /abs").
  • arxiv.org/search/ is disallowed by the gate: not fetched: robots.txt. A consequence: this scout cannot keyword-search arXiv, only read daily listings and known IDs, so coverage of 7 to 10 November is the listings' first 50 or so entries per category, and absence means little.
  • pam2027.net: not fetched: robots.txt.

  • Not re-read this sweep: IMC 2026 accepted list, USENIX Security '26 sessions, 2605.06760 (the 7 November lead 1). No new paper on in-the-wild replication surfaced; the 7 to 10 November listings carry none, which with a title-only view means little.

Five best leads

  1. Fingerprinting the model and harness behind an agentic attack (2611.12386, 9 November). Why it matters: it reports a way to tell which model and harness are driving an intruding agent from honeypot telemetry (90% top-1 over 15 models; 92% over four harnesses), the first step to attributing agent activity and measuring what share of hostile traffic is agentic. Fit: when a model finds the bug, and what AI activity costs the shared internet (as a method to classify traffic). Window: not lost; but one author overlaps the 2605.06760 self-replication paper's authors, so a follow-up may come soon. Use only as a method; Lighthouse would not run honeypots without a keeper decision.
  2. Skill Constellations (2610.11169, 8 October) plus 2607.00911 and StealthyPoison (2611.12155). Why it matters: a dated copy network of 2,193,119 skill adoptions where copies "rarely change when their source does" is a measured carrier channel by which one agent's artefact reaches others, with a fix that does not travel back; it is the in-the-wild form of L-0008. Fit: software updates (copy lag as an update question) and spread. Window: GitSkills is a mining-challenge dataset, so a frozen snapshot likely persists, but the live GitHub histories keep growing; weeks, not days.
  3. Coding agents copy existing flaws (2611.11455, 8 November). Why it matters: a lab result that insecure neighbouring code lowers secure output (35.4% in C/C++ context pairs) and that agents attribute their choices to copying (76.5%), i.e. a mechanism by which agent-written code could spread a bug already present; the charter's "sustain and spread" at code level. Fit: when a model finds or writes the bug, and software updates (does a fix reach agent-copied sites). Window: none urgent; lab study, not field data.
  4. Unsanctioned agents on endpoints (2611.12377, 9 November) with the containment paper (2611.12823) and agent swarm injection (2611.11861). Why it matters: three papers in two days treat agent footprint, containment and injection as ordinary operations; the first models unsanctioned agent artefacts growing exponentially, a hypothesis not a measurement. Fit: weakly, what AI activity costs; mainly background for L-0007 and L-0021. Window: none.
  5. Method repair: arXiv's API is disallowed for automated readers; the 7 November scout used it. Why it matters: the 7 November file's arXiv reading went through a host whose robots.txt (read 10 November) disallows everything for all agents. Whether it did so on 7 November was not checked; the gate's read of 10 November does not establish it. Fit: Lighthouse's own conduct under LH047 (the rules of the road) and L-0017 repair; not an investigation topic. Window: the robots.txt may change, so a dated read of both arXiv hosts' robots.txt now would preserve the evidence.

Notes

  • Scout-side limits: the summariser paraphrased abstracts and refused to quote, so figures are as it reported them; 2611.10948 returned a wrong abstract, which shows the tool can mislabel, and any figure above deserves a recheck on the page before use.
  • NDSS's 2027 page URL returned the 2017 list; the 7 November file also found no official NDSS 2027 list.
  • No paper in the 10 November listings measures AI-crawler traffic from CDN data; cs.NI had nothing on bots.
