v2 had no per-model defaults — generate_video hardcoded 30 steps/25 frames/480x832/cfg5/16fps for every model, badly wrong for e.g. LTX-2 distilled (wants 8 steps @1024x1536) or Wan2.2-TI2V (704x1280@24fps). - New SamplingDefaults dataclass + ModelCard.sampling_defaults (v2/card/specs.py), exported from v2.card. - Populated all 7 supported cards from fastvideo's InferencePreset defaults (steps/guidance/HxW/frames/fps + per-modality guidance for LTX-2.3 A/V). Negative prompts copied verbatim into v2/recipes/_prompts.py (recipe DATA, not model code -> v2-owned, no fastvideo import). - VideoGenerator stores the resolved card; generate_video applies card defaults with precedence kwargs > SamplingParam > card > generic fallback (pure _resolve_default helper, unit-tested). - test_sampling_defaults.py: per-card values + precedence (incl. empty-neg-prompt edge). CPU mini 210 pass, 2 skip.
