Mechanical conversion of every relative import under v2/ to an absolute v2.* path (from .x / ..x / ...x -> from v2.<pkg>.x) so imports are unambiguous, grep-able, and stable when code is copied/moved between entrypoints (VideoGenerator, CLI, server). Surgical prefix-only rewrite: only the 'from <dots><module>' prefix changed — import names, parentheses, multi-line formatting, comments, and ordering are byte-for-byte preserved (no collapsing, no reorder, no unrelated reformatting). - 471 imports across 125 files; v2/tests/ was already absolute (untouched). - Validated: all 125 files compile, every 'from v2.* import' target resolves to a real module/package, zero relative imports remain (full sweep), CPU mini suite green (202 passed, 2 skipped).

"""v2 — a scoped, CPU-testable realization of the design_v3 model-native runtime.
|
|
|
|
> A model card is a (recipe, runtime) pair with a parity obligation.
|
|
> The model owns loop semantics; the runtime owns loop lifecycle.
|
|
> One resident instance runs many loops; one scheduler runs their steps in one currency.
|
|
> Caches are correct by key; parity is correct by test; the interleave gate is non-negotiable.
|
|
> Training records behavior on the same loops it serves.
|
|
|
|
Phase 1 supports Wan2.1-1.3B (T2V) and LTX2.3 (2-stage distilled), plus four training
|
|
methods on Wan2.1-1.3B (finetuning, DMD2, DiffusionNFT, self-forcing). The spine is
|
|
omni-ready (multi-loop ModelInstance, ar_decode/chunk_rollout loop kinds) for the phase-2
|
|
Cosmos3 + vllm-omni omni ports.
|
|
|
|
The core is numpy-only and CPU-testable; heavy Wan/LTX neural forwards become lazy torch
|
|
adapters (see ``v2/models/*/components.py``) that are off the test path.
