Titles report a progressive trophy's progress with _UpdateTrophyProgress
events. Their udsNN.ucp rules feed $._trophy_progress into an int32
statistic with the max aggregation, filtered on $._trophy_id, and the
trophy's unlockCondition names that statistic. Those statistics and
rules were skipped and the events were dropped, so such trophies never
reported progress or unlocked (21 of Borderlands 4's 64).
- Read max statistics (largest value posted, from initialValue) and
int32 statistics (0 to 2147483647).
- Read a rule condition with one == property equal to an unsigned
integer, and apply the rule only to events whose property matches.
- Post _UpdateTrophyProgress through the statistic rules.

The 2026-10-21 split PRs added Export.cpp stub files to seven libraries
that have their own CMakeLists.txt, so core/libs/CMakeLists.txt never
adds Export.cpp for them and no target compiled the 101 stubs. A title
that imports one fails to load instead of throwing on the call.
Ngs2, Ngs2.native and AvPlayer.native build with hidden visibility, so
their stub files also need default visibility. libSceNgs2 already
compiled PendingExports.cpp, but its 6 stubs stayed local.
AnyPS5 resolves a title's imports by NID, so a title that imports a system
function that no AnyPS5 library provides fails to load with an unresolved
import. This declares 266 such exports across 4 PS5 system libraries that
AnyPS5 implements but does not provide.
Each declaration calls NotImplemented_nid_no_patch and returns 0; none of
them implements the function. The signatures are unknown for all of them, so
they are declared without parameters, which resolves the import without
making an ABI claim. The technical-debt files record the limitation per
library.
The list is the intersection of the export table of the console's library
(function symbols only), the pinned aerolib names and the functions not yet
defined anywhere in the repo. Every name recomputes to its NID with
tools/nid_names.py.
Events other than the trophy events go through the title's
sce_sys/uds/udsNN.ucp: stats_definition.json gives the statistics that
keep their latest uint32 or uint64 value, and stats_extraction.json the
event property ($.name, dotted for nested objects) that sets each one.
Statistics are kept per user and service label in
_trophy/<user id>_<service label>.stats.txt next to the unlocks.
After each event that sets a statistic, every trophy's unlockCondition
(ge, gt, le or lt against its targetValue) is checked on the values that
event set and the stored values of the other statistics, so a later
event setting the same statistic cannot hide what this one reached.
Reached trophies unlock through the same path as _UnlockTrophy.
Progressive trophies report their statistic as progress, and
APS5_TRACE_UDS prints each statistic an event sets. A missing udsNN.ucp
is ignored and a malformed one is logged once.
Events and property objects keep their typed properties instead of
dropping them. PostEvent records an _UnlockTrophy event with an int32
_trophy_id for the user and service label of its context, logs why a
trophy event is ignored, and prints every posted event with
APS5_TRACE_UDS.
The title's sce_sys/trophy2/trophyNN.ucp is read on first use with a
bounds-checked .ucp reader and a small JSON reader. tropconf.json gives
each trophy's grade, group, hidden and reward flags, platinum and
unlock condition, and tropmeta_<tag>.json its texts in the console
language, then en-US, then the file's default language. Contexts
remember their user and service label, so the queries find the file.
The trophy, group and game queries report these names, grades, groups
and counts, list every trophy and group, and give progressive trophies
their target. Unlocks are not recorded yet, so every trophy reports as
locked and nothing is written to the host. A missing file is ignored
and a malformed one is logged once; either way the queries keep their
placeholders. A JSON document that nests deeper than 64 levels or holds
more than 1048576 values counts as malformed, which keeps the parsed
values to about 140 MiB.
