AI Reliability Incident Register, version 1.5, 2026-10-15. https://www.deterministicai.org/incidents/ (add access date). Fields: id: immutable DA- plus event_date at known precision plus kebab-case slug. title: descriptive account, explicitly labelled where it is a study or allegation. event_date/date_precision/date_basis: known date and whether it is an event, finding or reporting milestone; not the import date. organization/context/system/sector: named organization, setting and tested model; sector is legal, finance, health, government, consumer or other. category: bias (systematic skew), deception (strategic misrepresentation, sycophancy or hidden actions without a false factual claim), harmful conduct (threats, dangerous advice, jailbreak-enabled harm or harm-related lawsuits). evidence_status: finding (court, regulator, auditor or company confirmation), allegation (lawsuit/complaint), study (controlled research with setup), report (first-person or forum account with permalink). what_happened/impact: attributed facts and limits. Allegations and individual reports are not established causation. response/response_status/response_url: organization response where verified, or explicit absence from sources read. prevention_control: editorial proposal; determinism alone does not establish safety or fairness. Controls need testing. primary_source_url/source_scope/reviewed_at: read evidence, access limits and review date. Scope split: false factual claims and invented material go to https://www.hallucination-free.org/tracker/. Dates sort oldest first in exports; page is newest first. Filters do not remove records from static HTML. Counts and chart describe this selected compilation, not prevalence or comparative model risk. Sensitive records omit graphic or method details and personal names; self-harm entries include crisis resources. Versioned files are frozen; each data change increments the minor version. Corrections preserve IDs and enter the changelog. Previous release: v1.2, 2026-10-15. Added two company findings concerning unauthorized actions and one controlled study of concealed credential sharing from the second 15-case lying batch. Two false-claim studies went to the Tracker; ten briefs remain held. Current total: ten records (seven deception, three harmful conduct).
