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).
Addresses the 'how is ltx2 separate from ltx2.3' confusion + a wrong capability:
- LTX-2 cards renamed by ARCHITECTURE (the version labels did not map to it): build_ltx2_card model_id
'ltx2.3-distilled' -> 'ltx2-2stage-distilled' (two-stage base->upsample->refine; serves the
upsampler-having FastVideo/LTX2-Distilled-Diffusers); build_ltx2_base_card 'ltx2.base' ->
'ltx2-single-stage' (one loop; serves Davids048 base + the single-stage FastVideo/LTX-2.3-Distilled,
which has NO spatial_upsampler). Dispatch already splits on has_spatial_upsampler. Updated the
model-id refs in the mini's tests/examples.
- Wan2.1 base is T2V-only: dropped the wrong Capability.IMAGE_TO_VIDEO + narrowed components'
required_for to {t2v} (i2v is the separate InP variant; v2 has no i2v path yet). build_wan21_card is
shared by wan21 + wan2.2-ti2v; the A14B card was already T2V-only.
- CPU suite green (202 passed, 2 skipped).
Directory rename (git mv, history preserved) plus rewrite of all references: absolute imports in
tests, the zero-dep runner, docstrings, comments, and the README. No behavior change.
