downloadGroup constant

String const downloadGroup

The background_downloader task group ALL model downloads run under. Single source of truth — cleanup / resume code that queries or resets tasks must use this exact group, or it operates on an empty set and silently no-ops (this is what caused the #383 leak amplifier: three call sites used the stale literal 'flutter_gemma_downloads').

Implementation

static const String downloadGroup = 'smart_downloads';
