Description

CI regenerates the models against the pinned spec and fails if the committed tree differs.
That check is failing on main.

release/2026-08-25 picked up the media variant schemas in 87dd4b1 ("feat(media): model
image, video, external video, and 3D variants (#690) (#941)"), so regenerating against the
pin now produces 232 modules where 227 are committed:

$ ./generate_models.sh 2026-08-25
postprocess: 36 module(s) patched
Done. Models generated in src/ucp_sdk/models/schemas

$ git status --porcelain src/ucp_sdk/models/schemas
 M src/ucp_sdk/models/schemas/common/types/media.py
?? src/ucp_sdk/models/schemas/common/types/media_external_video.py
?? src/ucp_sdk/models/schemas/common/types/media_image.py
?? src/ucp_sdk/models/schemas/common/types/media_model_3d.py
?? src/ucp_sdk/models/schemas/common/types/media_source.py
?? src/ucp_sdk/models/schemas/common/types/media_video.py

This commit is that output, unedited:

• media.py gains the Preview model and the current descriptions. The committed copy
  predates the backport.
• media_image.py, media_video.py, media_external_video.py, media_model_3d.py and
  media_source.py are new.

Post-processing patched its usual 36 modules, so the generated constraints are intact.

Checklist

• I have followed the Contributing Guide (including Conventional Commits title requirements and ! for breaking changes).
• I have updated the documentation (if applicable).
• My changes pass all local linting and formatting checks.
• I have added tests that prove my fix is effective or that my feature works.
• New and existing unit tests pass locally with my changes.
• (For Core/Capability) I have included/updated the relevant JSON schemas.
• I have regenerated Python Pydantic models by running generate_models.sh under python_sdk.

No new test or docs: the assertion this restores is the existing model-drift job in
tests.yml, which compares the committed tree against a fresh regeneration.

Hi @damaz91, tagging you because Universal-Commerce-Protocol/ucp#941 is what moved the pinned branch, so you'll have the most context on whether this output looks right.

Quick summary of what happened: python-sdk pins to release/2026-08-25, and CI runs ./generate_models.sh 2026-08-25. Your backport landed the media variant schemas on that branch on 22 Oct, so the pinned spec moved forward while the committed models stayed at their 5 Oct state. That's what the model-drift job has been failing on.

Nothing in this repo changed, and I haven't hand-edited anything here; it's purely the generator's output. It comes to six files: media.py picks up the new fields, and media_image.py, media_video.py, media_external_video.py, media_model_3d.py and media_source.py are new.

If you get a chance, a quick look to confirm they match what you modeled in Universal-Commerce-Protocol/ucp#690 would be great. Thanks!
