# D&D Item-Event Artifact
# D&D Item-Occurrence Artifact
This contract defines the durable item and currency occurrence list produced by
`dnd/item-events`. It records source-grounded discoveries and possession
changes; it does not maintain an inventory, balance, or ledger.
`dnd/item-events` currently produces this source-grounded item and currency
occurrence list. It records discoveries and possession changes, not an
inventory, balance, or ledger.
## Identity and compatibility
| Property | Value |
| --- | --- |
| Artifact kind | `dnd/item-event-list` |
| Schema ID | `notarius.dnd.item_events` |
| Schema name | `notarius_dnd_item_events_v1` |
| Artifact kind | `dnd/item-occurrence-list` |
| Schema ID | `notarius.dnd.item_occurrences` |
| Schema name | `notarius_dnd_item_occurrences_v1` |
| Schema version | `v1` |
| Media type | `application/json` |
`v1` is a strict JSON object with required `events`; the array may be empty.
Event and source-reference objects reject unknown fields. An incompatible
shape change requires a new schema version.
The strict root has required `occurrences`. Records require `item_id`, `name`,
`kind`, and `source_refs`; unknown fields are rejected. `quantity`, `from`, and
`to` appear only when their kind permits them.
## Registry grounding
Both extraction and normalization require an `item_registry` reference bound to
an earlier normalized `dnd/item-registry` artifact. The registry is immutable
for an operation and contributes only its ordered `{id,name}` projection after
the shared evidence message. It is never occurrence evidence.
Each occurrence must use one exact registry ID/name pair. Extraction omits an
unknown ID or mismatched name rather than creating an item. Normalization
canonicalizes a recognized name by ID, preserves unknown values for the
registry validator, and the registry validator rejects unknown or mismatched
pairs.
## Wire shape
Every event has required `name`, `kind`, and `source_refs`. `quantity`, `from`,
and `to` are optional where the event kind permits them.
| Field | Contract |
| --- | --- |
| `name` | Non-empty item or currency display name. |
| `kind` | `discovered`, `acquired`, `lost`, `consumed`, or `transferred`. |
| `quantity` | Optional positive integer; omit it when no count is established. |
| `from` | Optional non-empty losing holder, when allowed by `kind`. |
| `to` | Optional non-empty gaining holder, when allowed by `kind`. |
| `source_refs` | One or more transcript evidence ranges. |
Each source reference has exactly `source_id`, `start_unit_id`, and
`end_unit_id`. It identifies an inclusive current-transcript range; unit IDs
are positive and the start may not follow the end.

## Holder rules and minimal extraction
The five kinds remain `discovered`, `acquired`, `lost`, `consumed`, and
`transferred`. Holder, quantity, currency, ordering, and exact-duplicate rules
are unchanged: discovered has no holder; acquired requires `to`; lost and
consumed require `from`; transferred requires distinct non-`party` holders.
Each source reference is an inclusive current-transcript range.
`discovered` has neither holder; `acquired` requires `to` and forbids `from`;
`lost` and `consumed` require `from` and forbid `to`; `transferred` requires
both holders. `party` denotes collective possession. A transfer cannot use
`party` for either holder and its two normalized holders must differ.
Only an evidenced discovery or possession change belongs in this artifact.
It does not infer quantities or holders, convert currency denominations,
calculate balances, or merge nearby events. Campaign references may
disambiguate names but are never event evidence. Currency uses the ordinary
`name` field and an explicit `quantity` only when the transcript establishes
one; each denomination remains a separate event.
Normalization trims display whitespace, orders and removes exact duplicate
source references, then orders events by valid source chronology, name identity
and display value, kind, holders, quantity, and reference sequence. It
collapses only entries with the same normalized durable fields and complete
valid evidence.
The [JSON output contract](json-output.md) defines publication. See
[D&D module internals](../internal/dnd.md) for implementation details and the
[NPC-occurrence artifact](dnd-npc-occurrence-artifacts.md) for a distinct
kind of occurrence.
