  "description": "Samgöngustofa's (the Icelandic Transport Authority) Form US.140, 'Tilkynning um eigendaskipti að ökutæki' (Notification of Change of Vehicle Ownership), the single-page notification both buyer and seller of a private motor vehicle jointly complete and submit to record a change of registered ownership. Captures the vehicle's registration number, type, purchase-contract date, mileage, and (optional) sale price; the seller's and buyer's identity, address, and contact details; an optional second party on the buyer's side (a co-owner or an operator/'umráðamaður', with room for up to two named entries) and an optional co-owner on the seller's side; the buyer/operator's declared insurance company or the vehicle's out-of-use/trailer status; an optional override of the vehicle's usage category; the two required attesting witnesses' national ID numbers (one per party); and an optional payer identifier for filers paying the processing fee by bank transfer. Opens Iceland's DMV vertical (4th of 6), alongside is/skatturinn's Business Formation and Taxes schemas and is/utl's Visa schema. The form is submitted on paper (original notification delivered to Samgöngustofa); this document describes the form only and does not submit anything or imply government endorsement.",

    "notes": "GOV-2219 (child of GOV-2217, 'GovSchema Standard Research'): opens Iceland's DMV vertical (4th of 6), following Business Formation and Taxes (is/skatturinn) and Visa (GOV-2210's is/utl). Iceland's Passport and National ID verticals remain open, unscreened-or-dead-end backlog. Fetched fresh with a browser User-Agent directly from assets.ctfassets.net (HTTP 200, application/pdf, exactly 137,237 bytes, SHA-256 1aaea347530b0d736ff0dda6a5354c7d5f239cc59cd90738575dca5d70ed136a). The brief warned of a same-named but genuinely different flat/scanned mirror at samgongustofa.is/media/umferd/okutaeki/US_140-...pdf; the exact truncated URL 404s and the authority's current eigendaskipti landing page is a JS-rendered app shell with no directly-scraped PDF link, so the flat mirror could not be independently re-confirmed this session, but this schema is derived exclusively from the ctfassets.net specimen, which was itself independently confirmed to be a genuine fillable AcroForm (not flat) via pdfjs-dist re-extraction: doc.getFieldObjects() returned exactly 31 keys and page.getAnnotations() returned exactly 31 Widget annotations on the document's single page, matching the brief's own field-count claim and this document's own field list exactly. Every widget was cross-walked to its printed label using a position-aware (x/y proximity) script pairing each widget's rectangle with the nearest surrounding text, which surfaced two non-obvious structural findings, both recorded in VERIFICATION.md: (1) the 5 named-insurer checkboxes (INSU_6080/6090/6070/6075/6010) sit in the same two-column list as 2 further checkboxes literally named TRAILER (button value 98, 'Eftirvagn/tengitæki á tryggingu ökutækis') and OUT_OF_USE (button value 99, 'Úr umferð') — all 7 are one flat single-select list ('declare the vehicle's insurer, or that it is a trailer covered under the towing vehicle's own insurance, or that it is being taken out of use'), not an independent pair of checkboxes bolted onto a 5-option insurer group, and are modelled here as one enum field; (2) two unnamed checkboxes (pdfjs synthesised the keys 'undefined'/'undefined_2', meaning the source PDF's own AcroForm carries no /T entry for either — a genuine authoring omission in the government's own PDF, not an extraction artifact) tag whether the two numbered name lines below them (OPER_NAME_1, OPER_NAME_2) name a co-owner ('meðeiganda') or an operator ('umráðamanns'); modelled as a single enum field per this registry's established preference (is/utl, at/bmeia, se/migrationsverket) for a true single-select-among-named-values grid over exclusivityGroups, which spec reserves for independently-named booleans with their own sub-fields. See VERIFICATION.md for the full sourcing record, every scope decision, and the mock conformance test run."
