sc_missions_v1.accept

Accept the exact current broker/offer/generation with a nonzero owner/session idempotency key. Duplicate identical requests return the original handle without another effect; changed input with the same key is BAD_ARG. At most 64 retained acceptance receipts per session; no eviction.

Parameters and buffers

sco_result (*accept)(sco_plugin* self, const sc_mission_offer* offer, uint64_t key, uint64_t* out_mission);
Accept the exact current broker/offer/generation with a nonzero owner/session idempotency key. Duplicate identical requests return the original handle without another effect; changed input with the same key is BAD_ARG. At most 64 retained acceptance receipts per session; no eviction.

Results and failures

OK on success; BAD_ARG invalid/short input or released handle; UNAVAILABLE absent backend/unsafe admission; NOT_FOUND unknown IDs; TOO_MANY bounded quota; FAILED refused progression/provider failure; CRASHED latches restart required. Outputs untouched on failure.

Absent capability

Missing table: query_service NOT_FOUND; absent method/backend or unsafe admission: UNAVAILABLE.

Ownership

Caller-owned copied buffers; no allocation transfer. Mutations scoped to live plugin and current offline session.

Thread affinity

Game thread only; WRONG_THREAD before backend access.

Callback context

Backend callbacks synchronous on game thread; pointers valid only during call.

Reentrancy

Recursive calls and Stop/replacement during callbacks refused (FAILED).

Cleanup and cancellation

Consumers unload before Stop. Released owners lose mutation authority. No automatic persistence or replay of uncertain effects. Native faults permanently close admission until process restart.

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.

Language	Catalogue status	Source evidence / wrapper tokens
c	direct	include/sc_missions.h `(*accept)`
cpp	direct	include/sc_missions.h `(*accept)`
csharp	unsupported	docs/design/offline-missions.md `C# and Lua bindings are unsupported`
lua	unsupported	docs/design/offline-missions.md `C# and Lua bindings are unsupported`

Examples

None identified in the catalogue; this is not proof none can exist.

Tests

ABI pins prove layout, not semantic behavior or a live game session.
