USAGE.md describes the refused posted unlocks and their log line, and says that the icon queries and a damaged or unwritable unlock or statistics file stop the game with an error. The debt entries of libSceNpTrophy2 and libSceNpUniversalDataSystem no longer say that any posted id is stored. Both USAGE.md and the libSceNpTrophy2 entry say that without trophy data the platinum is not unlocked when the other trophies are.

# libSceNpUniversalDataSystem technical debt

### Unknown function info
|
|
|
|
- [Events](../../../core/libs/prx/libSceNpUniversalDataSystem/src/Event.cpp): `sceNpUniversalDataSystemCreateEvent` copies `prop` and returns the event's own property object through `prop_ptr`, as [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/9e41d8320a2774b303fbad344c2347e8d0292e83/src/libs/libTrophy.cpp) does; `sceNpUniversalDataSystemEventPropertyObjectSetObject`, `SetArray` and the array setters for objects and arrays store a copy of `value` and return the stored copy through `value_ptr`. Destroying a property object or array that its Create function did not return (an event's property object or a stored copy) does nothing, as its owner frees it. These ownership rules are not verified on a console, nor are the output of `sceNpUniversalDataSystemEventToString` (still `{}`) and `sceNpUniversalDataSystemEventEstimateSize` (still 3).

### Functional
|
|
|
|
- [Trophy events](../../../core/libs/prx/libSceNpUniversalDataSystem/src/Event.cpp): `sceNpUniversalDataSystemPostEvent` stores an `_UnlockTrophy` event with an int32 `_trophy_id` of 0 or more as an unlock for the user and service label of its context, as KytyPS5 does, except an id that [libSceNpTrophy2](../../../core/libs/prx/libSceNpTrophy2/src/TrophyStore.cpp) refuses when the title's trophy data is loaded (one not in the data, a platinum or a progressive trophy). `_UpdateTrophyProgress`, named only by a third-party unlocker, is logged once per trophy and not interpreted. A context need not be registered, and every post of an event that `sceNpUniversalDataSystemCreateEvent` returned and that is not yet destroyed returns success (a null or any other event pointer stops the game): KytyPS5's errors for an unknown or unregistered context and for a malformed unlock are not verified. The storage statistics stay zero.
|
|
- [Statistics](../../../core/libs/prx/libSceNpUniversalDataSystem/src/Event.cpp): every other event goes through the title's rules in `sce_sys/uds/udsNN.ucp`, which [libSceNpTrophy2](../../../core/libs/prx/libSceNpTrophy2/src/TitleTrophies.cpp) reads. Only statistics with `"aggregation":"latest"` and `dataType` `uint32` or `uint64` are kept, as in KytyPS5; no public source documents the other aggregations or types, so their definitions and rules are skipped. Only rules whose condition is an `eventName` alone and whose input is a `$.name` path (dotted for nested objects) are applied. A value is used when it is an integer of any width that is not negative and fits the statistic's type and `minValue`/`maxValue`; KytyPS5 requires the statistic's exact width, and whether the console converts, clamps or rejects other values is not known. Statistics are stored per user and service label, and every trophy's `unlockCondition` is compared after each event that sets one.
