Record model downloads by repository, revision, path and integrity evidence

Purpose and scope

A model name can cover bundled checkpoints, split weights, quantized variants, text encoders and VAEs. Preserve enough identity information to know which artifact a workflow actually used.

Source-supported context

Hugging Face Hub supports explicit revision and file paths and distinguishes cache from local_dir. Names and sizes are clues, not independent integrity proof when the publisher supplies no reliable expected value. Source 1 Source 2 Source 3

Before you start

1. Identify each required diffusion model, encoder, VAE, LoRA and node-code dependency from the workflow.

2. Record the original author or converter, model family and source of usage restrictions.

3. Confirm storage headroom, gated access and the identity used by the downloader.

Steps and checks

The sequence below is an editorial procedure based on the cited context, not a diagnosis already confirmed for your environment.

Step 1. Keep one record per file with provider, repository, revision, relative path and destination. Mark unknown revisions explicitly.

Step 2. Use an official release route and select needed files instead of downloading a whole repository by default. A saved webpage is not a weight file.

Step 3. Record the downloaded size and compare a reliable upstream checksum with the same algorithm where available. A locally computed hash alone does not establish publisher identity.

Step 4. Before loading, check loader, precision and companion models, preserving the check date and unknowns. A new revision should not silently overwrite the old identity record.

Completion check

The artifact can be traced and download completion, integrity comparison, loading and workflow execution are recorded as distinct states.

Limitations and cautions

Do not mutate Hub cache objects or publish private tokens. Treat mirrors as identical only when reliable content-identity evidence supports that relationship.
