"""Tests for the bundled DeepInfra video_gen plugin.
Invariants only — no snapshots of specific model ids. The plugin is a thin
subclass of ``agent.video_gen_provider.OpenAICompatibleVideoGenProvider``;
these tests pin the plugin-specific bits (tag filtering, identity) and the
shared base behaviour exercised through it (OpenAI ``videos`` call shape,
t2v vs i2v routing, download → save).
