sceNpAppLauncherLaunchApp returned the libSceNpGameIntent codes 0x80553802/0x80553804, but the firmware tail remaps the internal launch library errors into the launcher family, so the export reports 0x80553A02 before initialize and 0x80553A04 on invalid arguments; the tests now assert those values and the unrelated GameIntent constants are untouched. The two assertions that a valid launch call must throw until implemented are removed; the production throw and its debt entry stay, and the validation and lifecycle coverage is unchanged. The debt file keeps the silent-stub, InitParamInit, InfoInit and remaining unknown-export entries, updating only the launcher parts.

# libSceNpGameIntent technical debt

### Silent stubs
|
|
|
|
- [sceNpGameIntentVshInitialize, sceNpGameIntentVshTerminate](../../../core/libs/prx/libSceNpGameIntent/Export.cpp) (libSceNpGameIntent) - VSH initialization and termination return 0 without performing shell operations, matching `sceNpGameIntentInitialize` and `sceNpGameIntentTerminate`
|
|
- [sceNpAppLauncherInitialize, sceNpAppLauncherTerminate](../../../core/libs/prx/libSceNpGameIntent/Export.cpp) (libSceNpGameIntent) - app-launcher lifecycle returns success without performing launch work; `sceNpAppLauncherInitialize` accepts its init parameter without validation, following the silent-stub precedent of `sceNpGameIntentInitialize` — a title calls it early in boot, and returning success lets it continue; an atomic flag tracks initialized state so `sceNpAppLauncherLaunchApp` can reject calls made outside the lifecycle

### Unknown function info
|
|
|
|
- [sceNpGameIntentReceiveIntent, sceNpGameIntentGetPropertyValueString](../../../core/libs/prx/libSceNpGameIntent/Export.cpp) (libSceNpGameIntent) - firmware 13.42 traces report `0x80553802` before `sceNpGameIntentInitialize` (precedence over argument validity), and `0x80553804` for invalid arguments (null pointer, empty key, or zero buffer size); `sceNpGameIntentTerminate` resetting initialized state is modeled lifecycle behavior rather than hardware-verified. `sceNpGameIntentReceiveIntent` reportedly requires `info->size == 0x4140` on firmware 13.42, while AnyPS5 `NpGameIntentInfo` is `0x560` bytes (matching fpPS4) and set by `sceNpGameIntentInfoInit`, so initialized objects are rejected by the receiver's measured size guard. Complete retail layout, output field offsets, and retail behavior of `sceNpGameIntentInfoInit` are unverified; expanding the type with unverified reserved bytes is not an evidence-backed solution.
|
|
- [sceNpAppLauncherLaunchApp](../../../core/libs/prx/libSceNpGameIntent/Export.cpp) (libSceNpGameIntent, NID `GbayQ7DO8jA`) - its recovered signature is `(int32_t, const char*, const char*)`: an unhandled first argument, a required non-empty string and an optional string rejected past 0x2000 bytes, returning `0x80553A02` before `sceNpAppLauncherInitialize` and `0x80553A04` on invalid arguments. The launch itself is not implemented and throws; the firmware tail calls an internal launch through an extra library context and remaps its `0x805538xx` errors into `0x80553Axx`
|
|
- [sceNpGameIntentGetUdsNpComId, sceNpGameIntentLaunchApp, sceNpGameIntentLaunchApp2, sceNpGameIntentNotifyAppLaunched, sceNpSessionServiceGetJoinedPartySession, sceNpSessionServiceGetRunningGamePlayerSession and sceNpSessionServiceSendPlayerSessionInvitations](../../../core/libs/prx/libSceNpGameIntent/Export.cpp) (libSceNpGameIntent) - names and NIDs are present in the [PS5 3.20 export inventory](https://github.com/DNNDHH/PS5-3.20_Libs/blob/b2a77c09cd71c01f34c790cfbe98c751a13262ad/libSceNpGameIntent.c). They are declared without parameters solely to resolve known imports and make no ABI claim.
|
|
- [sceNpGameIntentInitParamInit](../../../core/libs/prx/libSceNpGameIntent/Export.cpp) (libSceNpGameIntent) - struct layout matches [fpPS4](https://github.com/red-prig/fpPS4/blob/master/src/np/ps4_libscenpgameintent.pas#L17) `SceNpGameIntentInitParam`; setting `size`, zeroing reserved bytes, and throwing on null pointer follow Sony SDK `*ParamInit` conventions but are unverified on retail hardware
|
|
- [sceNpGameIntentInfoInit](../../../core/libs/prx/libSceNpGameIntent/Export.cpp) (libSceNpGameIntent) - struct layout matches [fpPS4](https://github.com/red-prig/fpPS4/blob/master/src/np/ps4_libscenpgameintent.pas#L28) `SceNpGameIntentInfo`; setting `size = 0x560`, `user_id = -1`, zeroing fields, and throwing on null pointer follow fpPS4 defaults, but reported firmware 13.42 behavior requires `0x4140` for `sceNpGameIntentReceiveIntent`, so the helper's `0x560` size does not match retail receiver defaults; the complete retail structure layout and retail behavior of `sceNpGameIntentInfoInit` remain unverified
