Parameters and buffers

sco_result (*cancel)(sco_plugin* self, uint64_t ticket);
Owner-only idempotent cancellation of a known ticket. Does not undo movement already initiated. Foreign or evicted tickets are NOT_FOUND. Zero ticket is BAD_ARG.

Results and failures

SCO_OK success; SCO_BAD_ARG invalid input/self; SCO_UNAVAILABLE missing safety/player/transport or unknown/different systems; SCO_TOO_MANY pending global request or ticket exhaustion; SCO_NOT_FOUND foreign/unknown/evicted ticket. Outputs unchanged on failure.

Absent capability

Missing service: query_service NOT_FOUND. Production table is present but game.relocation capability false; valid request returns SCO_UNAVAILABLE.

Ownership

Local player only; owner-scoped opaque tickets. No arbitrary entity/pointer/owner writes. Copied request and caller-owned output. 32 retained terminal tickets; oldest terminal evicted at admission.

Thread affinity

Game thread only; wrong thread returns SCO_WRONG_THREAD without touching state.

Callback context

No callbacks; bounded tick-driven work.

Reentrancy

Non-reentrant.

Cleanup and cancellation

Owner unload cancels/forgets tickets; stop forgets all; ticket sequence never recycled. Session/player/system change, safety/transport loss or fault fails pending. Stream loss waits up to timeout. Completion requires fresh pose within 0.05m and quaternion absolute normalized dot at least 0.999999. Cancellation is not undo.

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.
