Extract this fictional museum loan inventory. Return JSON only, without Markdown. The root has exactly one key, items. Each item has exactly id, title, gallery, insurance_usd, arrival_date. Preserve the stated item order. insurance_usd is a nonnegative JSON number or null; an explicitly confirmed zero is 0, not null. arrival_date is an actual calendar date in YYYY-MM-DD or null. Missing, unapproved, conflicting or impossible values must be null. Never choose between conflicting unapproved estimates. Do not infer facts.

A1: Brass compass. Gallery A. Approved insurance USD 12000. Arrival 2026-11-14.
B2: Silk route map. Gallery B. Draft insurance estimates: USD 8000 in one note and USD 9000 in another; neither approved. Arrival 2026-11-16.
C3: Ceramic sherd. Insurance is explicitly confirmed as USD 0. Gallery and arrival date are unconfirmed.
D4: Glass lens. Gallery D. Approved insurance USD 500. Arrival is written as 2026-02-30; the actual date has not been confirmed.

{"items":[{"id":"A1","title":"Brass compass","gallery":"A","insurance_usd":12000,"arrival_date":"2026-11-14"},{"id":"B2","title":"Silk route map","gallery":"B","insurance_usd":null,"arrival_date":"2026-11-16"},{"id":"C3","title":"Ceramic sherd","gallery":null,"insurance_usd":0,"arrival_date":null},{"id":"D4","title":"Glass lens","gallery":"D","insurance_usd":500,"arrival_date":null}]}

For gallery, preserve the full source label exactly (for example, "Gallery A", not "A"). Never shorten or translate these labels.
