- constants stub: use mt_rand()-based exprs so PHPStan infers GENERAL types,
not literal 0/'' — fixes false division-by-zero (PACKET_SIZE) and
foreach-over-false (str_split with len 0). Load stub via bootstrapFiles so
result-cache invalidates on change.
- return contracts: explicit returns where a path fell through to null and
violated the declared type:
- StreamRepository::getById/getWatchFolder, GroupService::getById,
getStream() → return false (declared array|false).
- ServerRepository::getPublicURL → return '' when server missing (array→string).
- MagService::resetSTB → return query() result (declared bool).
- StreamUtils::getPlaylistSegments → explicit return null.
- NetworkUtils::stopDownload → @return null corrected to @return void.
- PlexController: getPlexToken() called with 5 args but accepts 4 — dropped
the dead 5th argument.
- DropboxClient::getMetaFromHeaders: array_shift() on an array_filter()
expression (not a variable, by-ref error) — assign to a var first.
- WatchdogCommand: wrap numeric-string subtractions (nginx/proc-stat values)
in floatval()/intval().
