feat: add P-H3-Image generation and editing support - #2272
No actionable comments were generated in the recent review.
Walkthrough
This change adds P-H3-Image model detection, text conditioning, single-frame VAE handling, reference-image generation, and CLI configuration. It also adds usage documentation and reformats several existing C++ and shader declarations.
Changes: P-H3-Image support
Layer / File(s)
Summary
Model identification and tensor routing src/model.h, src/model/integrations/minimax_h3.cpp, src/model_loader.cpp, src/name_conversion.cpp
Adds the P-H3-Image version and model definition. Model loading detects P-H3-Image from tensor metadata and routes connector tensor names.
Text connector and prompt conditioning src/model/te/ph3_image_connector.hpp, src/conditioning/conditioner.hpp
Adds the P-H3 text connector and integrates it into LLM setup, runtime configuration, prompt encoding, and image-edit prompt handling.
Adds VAE configuration detection and single-frame behavior, including latent sampling and frame checks. VAE construction validates the P-H3-Image weight shape and handles construction exceptions.
Image generation and reference images src/pipeline/diffusion_engine.cpp, src/pipeline/image.cpp
Sets P-H3-Image diffusion and latent-decoding behavior. Adds reference-image resizing, latent packing, reference metadata, and hires-fix handling.
CLI, recipe, and documentation support examples/common/common.cpp, examples/server/recipes/*, README.md, docs/p_h3_image.md
Adds the sigma preset, recipe configuration, supported-model listing, and P-H3-Image usage guidance.
No actionable merge-blocking risk remains established for this change.

Full details: Docstring Coverage
Explanation
Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 38 functions across 12 files.
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

Review comments at @src/pipeline/model_builders.cpp:
- Around line 165-166: Update build_vae_runners so a missing or incorrectly
shaped P-H3 projection logs the validation error and returns false instead of
letting the runtime_error escape; alternatively, catch VAE construction errors
at the builder boundary and propagate failure to the caller. Preserve the
existing projection validation and ensure the failure is reported through the
established load-failure path.
