Promote to production: OCR model cache fix + voice cache indicator - #107
Merged
Conversation
… re-download after refresh
- PaddleOCR fetches its model from raw/media.githubusercontent.com (git-LFS);
those hosts weren't in the SW ml-models-cache rule, so the OCR model
re-downloaded on every refresh. Add them to the CacheFirst urlPattern
alongside Hugging Face + jsDelivr.
- VoiceToText: the transformers.js progress bar fires even on cache hits,
which read as a re-download. Add a definitive modelCached check
(caches.open('transformers-cache')) and label the bar accordingly.
Audit note: the other model tools (background-removal, ffmpeg, face-blur,
upscale, object-remove) load same-origin from /models/* served
'immutable, max-age=1yr' by the worker, so they cache on the HTTP layer and
need no SW rule.

Promotes #106: stop the PaddleOCR model re-downloading on refresh (add githubusercontent hosts to the SW CacheFirst rule) and add an honest cache indicator to Voice-to-Text. Audit confirmed the other model tools cache via same-origin immutable /models/*.
