Mechanical, whole-tree `ruff format` pass — no behaviour change. Recorded in .git-blame-ignore-revs (next commit) so git blame skips it.

"""download editor (phase 2): per-user trim/crop derivatives
|
|
|
|
Revision ID: 0041_download_edit
|
|
Revises: 0040_reset_profiles
|
|
Create Date: 2026-07-04
|
|
|
|
Adds the editor columns to `download_jobs`. An edit job (`job_kind='edit'`) derives a new per-user
|
|
clip from an already-downloaded job by running ffmpeg (trim = stream-copy, crop = re-encode). It
|
|
still hangs off a `media_assets` row (with `source_kind='edit'` and a per-user cache key) so the
|
|
existing file-serve / ref-count / GC / quota machinery is reused unchanged. `source_job_id` /
|
|
`source_asset_id` point at the parent download; `edit_spec` is the trim/crop recipe.
