+Extract meaningful Dungeons & Dragons item and currency occurrences: discoveries and changes
+in party possession established by the transcript. This is an occurrence history,
+not an inventory or ledger: do not calculate balances, resolve item identity
+across records, or infer ownership that the transcript does not establish.
+
+For every occurrence, copy the exact `item_id` and `name` pair from the supplied
+item registry. Record a stated quantity as an integer and leave it null when the transcript
+does not state one. Use a concise observed item name and preserve the stated
+currency denomination.
+
+Use `discovered` when the party learns of or encounters an item without
+establishing possession. Use `acquired` when the party or a party member gains
+possession. Use `lost` when party possession ends through a gift, sale, payment,
+theft, abandonment, or destruction not caused by intended use. Use `consumed`
+when intended use depletes an expendable item. Monetary spending, purchases, and
+payments are always `lost`, not `consumed`. Classify currency as `consumed` only
+when the transcript explicitly describes it being physically destroyed or
+expended as a non-payment component. Use `transferred` only when possession
+moves between two distinct named party members.
+
+Return both `from` and `to` for every occurrence, using `null` when a holder does not
+apply. For `discovered`, set both holders to `null`. For `acquired`, set `from`
+to `null` and provide `to`; for `lost` and `consumed`, provide `from` and set
+`to` to `null`; and for `transferred`, provide both holders. Use `party` only
+for collective or unresolved party possession, never for either side of a
+transfer. Do not emit a transfer for a gift, sale, or payment outside the party.
+
+Ordinary non-depleting use is not an occurrence. Do not infer acquisition from a
+discovery, or discovery from an acquisition: emit both only when each is
+independently established.
