Prior Depth Anything is a depth-completion prior: it takes any coarse or sparse metric-depth prior plus an image and refines them into a dense, sharper metric depth map. In this catalog it is verified — the Workspace loaded the official checkpoint and refined a real Depth Anything 3 metric-depth condition on 2026-07-11.

## What it is for

Use `prior-depth-anything` for catalog geometry inference. Choose it when the artifact is a reconstruction, not a generated video.

The catalog records a prompt-conditioned depth-completion design: the model consumes prompt metric depth alongside the image (checkpoint Rain729/Prior-Depth-Anything, apache-2.0). It is registered at base_models/three_dimensions/depth/priorda and shared by higher-level geometry pipelines without being nested under them.

Catalog tasks include depth-completion, metric-depth-estimation, and geometry-prior. Catalog aliases include `priorda` and `prior-depth-anything-prior`. Documented modalities: image in, depth out.

## Runtime contract

Optional `input_path`, `prompt_depth_path`, `prior_depth_path`, `execute`, and `max_points`; artifacts `prior-depth-anything.npz`.

CLI task profiles: `default`. WorldFoundry binds `PriorDepthAnythingPipeline`.

Family status: **Verified**.

It is integrated as an independent geometry prior under worldfoundry/base_models and exposed through the shared geometry-prior pipeline/operator contract. Higher-level pipelines (e.g. ViPE) import it from this canonical owner instead of keeping private copies. Pair it with a metric source (e.g. depth-anything-v3-prior) whose output it refines.

Integrated as an independent depth-completion prior at worldfoundry/base_models/three_dimensions/depth/priorda.

## Running in WorldFoundry

The catalog launch is `worldfoundry-eval run prior-depth-anything --pipeline.task-profile default`. The command builder above switches `--pipeline.task-profile` among recorded tasks and still emits `worldfoundry-eval run`.

It runs in the unified environment `worldfoundry-unified-cu128` (Python 3.11, CUDA 12.8).

Recorded weight repositories include `Rain729/Prior-Depth-Anything`. Prepare the environment and check local assets with `bash scripts/inference/prepare_model_infer.sh prior-depth-anything`. Add `--download` to fetch missing public checkpoints.

Recorded licenses include apache-2.0; status: **Verified**.
