Summary

Consolidated PR — includes everything from PR #20 (codex/pr19-layered-port) merged with additional features. Supersedes #20.

From PR #20

  • Wan2GP v10.83 sync — apply_changes → get_default_settings/set_model_settings
  • LTX-2 19B support — latent injection, multi-frame guide images, IC LoRA + union control routing
  • Uni3C restoration — hard-fail on param drops, centralized model settings
  • Travel VACE fix — restrict detection to explicit VACE models only
  • LTX-2 travel pipeline — native keyframe anchoring, model-aware frame quantization (8N+1), 24fps, audio mux
  • 1817-test suite — 113 test files covering headless, GPU, and regression scenarios
  • Wan2GP upstream — new model configs, Uni3C controlnet

New (not in PR #20)

Test plan

  • Verify ltx2_controlled payloads (IC-LoRA, LoRA, image guides, combined)
  • Verify existing ltx2, ltx2_multiframe, ltx2_ic_multiframe backward compat
  • Run headless test suite
  • Verify LTX-2 travel pipeline

Supersedes #20.

fix: remove apply_changes import for WGP v10.83 compatibility
ce277ac 
WGP v10.83 removed the apply_changes() function - config is now applied
at module level during import. Updated headless_wgp.py to directly set
output paths on wgp module-level variables instead. Also added GPU test
script for LTX-2 19B validation.

feat: port LTX-2 support to refactored orchestrator location
1b8257b 
After syncing with upstream's structural refactoring (headless_wgp.py →
source/models/wgp/orchestrator.py), port all LTX-2 19B integration
changes to the new file location:

- Add _is_ltx2() detection method + generation_helpers implementation
- Update smoke mode stubs for ltx2/qwen model detection
- Add LTX-2 image/audio parameter bridging (start_image → image_start,
  audio_input → audio_guide, auto image_prompt_type detection)
- Add WGP v10.83 parameters: alt_prompt, duration_seconds, pause_seconds,
  audio_scale, input_video_strength, override_attention, custom_settings,
  top_k, self_refiner_* to both passthrough and normal mode param dicts

paths that moved during upstream refactor. Also fix SupabaseClient
union type annotation for environments without supabase installed.

feat: add LTX-2 model compatibility across travel pipeline
3950ec4 
Introduce model-aware parameterization so the travel pipeline supports
both Wan (grid=16, frame_step=4, fps=16) and LTX-2 (grid=64,
frame_step=8, fps=24) without breaking existing behavior.

Key changes:
- resolution_utils: add get_model_grid_size(), parameterize grid snapping
- orchestrator: replace hardcoded //4 quantization with _quantize_frames(frame_step),
  add model-aware FPS helpers, auto-disable SVI for LTX-2
- preflight: parameterize min_frames safety check (Wan=5, LTX-2=17)
- segment_processor: add LTX-2 TSEV prompt type builder
- stitch: model-aware FPS fallback, audio mux from segments
- ffmpeg_ops: add video_has_audio() and mux_audio_from_segments()
- task_registry: pass grid_size to snap_resolution_to_model_grid
- lora_utils: add ltx2 lora cleanup path

fix: add missing parse_phase_config import in task_conversion
216df7d 
The function was being called but never imported, causing all
phase_config-related tests to fail (11/147). It was likely missed
during the refactoring that moved it to source/core/params/.

feat: add union control LoRA support for LTX-2 IC-LoRA pose workflow
69cc46b 
- Add union control LoRA URL to ltx2_19B.json preload_URLs
- Update get_loras_transformer() to use single union LoRA when multiple
  control types requested (P+D, P+E, etc.), fallback to separate LoRAs
  for single control type
- Add smoke test (test_ltx2_pose_smoke.py) with AST-based verification
- Add workflow parameter reference (ltx2pose_params.py)
- Add GPU tests for pose workflow params and union control (PDVG)

feat: add LTX-2 multi-frame guided video workflow
f07f666 
Implements a new ltx2_multiframe task type that generates video with 4
guide images at configurable frame positions via ComfyUI. Image 4 is
encoded directly into the latent (inplace), images 1-3 are guide
conditioning at specified frames.

New files:
- ltx2_multiframe_workflow.py: builds API-format ComfyUI workflow
- ltx2_multiframe_handler.py: task handler (download, upload, execute)
- ltx2_multiframe_params.py: reference parameters
- test_ltx2_multiframe_smoke.py: structure/wiring smoke tests
- test_ltx2_multiframe_gpu.py: GPU integration tests

Modified:
- comfy_utils.py: add upload_image() to ComfyUIClient
- task_types.py: register ltx2_multiframe model mapping
- task_registry.py: register handler in dispatch
