+  transcribing is refused (409) until it ends**, because the worker would otherwise write to a

+  The home list now links to `/uploads` when uploads are mounted.
 
 **Reversibility.** Additive: one table (down-migration drops it), one adapter, one upload
 surface, one image change. Removing the upload route removes the feature; `transcripts`, `videos`
