Catalogue snapshot — development preview

SDK 2.3.0 · game pack 0.6.0 · source e616ed69d8f9f77b0f4827881c86d91e4a7d1689 Published release: sdk-v2.3.0 (immutable approved assets; this development preview is not an approved release). Source-backed inventory is not a runtime or in-game verification claim.

out_actor = the actor in seat seat_index of ship, or 0 when the seat is empty. SCO_FAILED when the seat is occupied but the game pack can’t tell by whom (last_error has the raw field); SCO_NOT_FOUND for a ship that isn’t streamed in or an index past the last seat. game.vehicles.seats.

Limitations / unestablished guarantees

• internal allocation unspecified.
• Recursive reentrancy unspecified.
• released-handle refusal unspecified.
• Additional failures/output state unspecified unless described in the buffer contract.
• Game-service behavior not verified in a game session.

Parameters and buffers

sco_result (*seat_occupant)(uint64_t ship, uint32_t seat_index, uint64_t* out_actor);
out_actor = the actor in seat seat_index of ship, or 0 when the seat is empty. SCO_FAILED when the seat is occupied but the game pack can’t tell by whom (last_error has the raw field); SCO_NOT_FOUND for a ship that isn’t streamed in or an index past the last seat. game.vehicles.seats.

Results and failures

Absent table: query_service NOT_FOUND; missing operation capability: UNAVAILABLE; self validity as checked by implementation; released-handle refusal unspecified. Additional failures/output state unspecified unless described in the buffer contract.

Absent capability

Absent table: query_service NOT_FOUND

Ownership

Caller outputs; IDs/seat indexes are streaming-session values. No allocation transfer; internal allocation unspecified.

Thread affinity

Game thread only (WRONG_THREAD elsewhere); last_error any thread. Recursive reentrancy unspecified.

Callback context

unspecified

Reentrancy

unspecified

Cleanup and cancellation

No in-flight cancellation entrypoint; game acceptance need not mean action completed.

Language mappings

Status labels are copied verbatim from the catalogue: direct is native access; typed-wrapper is wrapper-backed; restricted is a subset/adaptation; unsupported means no supported route is established. No status implies universal safety.
