ps5upload/payload/tests/activity_json_selftest.c

/*
 * Host self-test for the Game Activity wire format — activity.c's three
 * JSON producers, compiled for real rather than re-implemented.
 *
 * Two bugs motivated this file, and neither was reachable by the older
 * activity_launch_selftest.c, which copies the arithmetic instead of
 * building the source:
 *
 *   1. activity_get_json() emitted "last_played" and "active", but the
 *      engine's ActivityEntry declares last_launch_ts and session_active,
 *      every field #[serde(default)]. The mismatch did not fail to parse;
 *      it silently produced zeros, so the UI's "Last played" read "—" and
 *      the Active badge could never light up.
 *
 *   2. Only the recently-played query carried a title name, because it is
 *      the only one sourced from app.db. The tracked list comes from the
 *      process watcher and the play-time list from the system logger, and
 *      neither source has a name column -- so two of the three tabs showed
 *      bare title ids.
 *
 * Including the .c gives the test the file's statics (record_launch,
 * play_time_json) without widening the header for testing's sake.
