[feat] v2 port: Wan2.2-TI2V-5B (T2V) — 4th GPU-verified model
- Wan2.2-TI2V-5B reuses the Wan adapters (WanTransformer3DModel / AutoencoderKLWan / UMT5); deltas
are the higher-compression VAE geometry (z_dim=48, 16x spatial, 4x temporal) and 480p flow-shift 5.0.
The DiT forward accepts a scalar timestep (1D path), so no per-frame expand_timesteps for pure t2v.
- WanDenoiseLoop / build_wan21_card gain optional geometry params (latent_channels/spatial_ratio/
temporal_ratio) defaulting to Wan2.1 (16/8/4) -> wan21 path unchanged; build_wan22_ti2v_card sets
48/16/4. Registered as family 'wan2.2-ti2v' in VideoGenerator; v2_basic_wan2_2_ti2v.py added (T2V).
- Verified: 25x448x768 mp4, std 62.3, inter-frame motion 4.89 (coherent). CPU suite green (202+2skip).
- Corrected the now-disproven FastWan='wan21 reuse' mapping (its DMD checkpoint to_gate_compress param
mapping differs); roadmap updated (TI2V-5B working; A14B MoE + I2V remain).
