Return one event only when the transcript establishes a meaningful item or
currency occurrence. Use a concise observed item name and preserve the stated
currency denomination. Set `quantity` to the explicitly stated integer, or to
`null` when the transcript does not state one.

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 event, 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 event. Do not infer acquisition from a
discovery, or discovery from an acquisition: emit both only when each is
independently established. Every event needs at least one narrow transcript
range. Return no lore, inventory totals, aliases, or unstated holder details.
