Steps 3 and 4 of the build order. A member can now upload a song, watch it
convert, publish it, and review what everyone else has published.
Pipeline:
- ffprobe reads tags synchronously at submit so prefill never races typing;
ffmpeg converts to Opus in the background, two at a time
- ffmpeg succeeding is the validation — no container sniffing
- publish moves the file inside the transaction, so a song row and its .ogg
appear together or neither does
- five submissions per rolling 24h, failures excluded
Reviews and the reveal rule:
- the queue is unreviewed songs only, oldest first, never your own
- other people's reviews and the average are withheld in the query, not the
template — a hidden average is never sent
- 30 minutes to edit or delete your own review, enforced in the WHERE clause
- deleting the last review unlocks the song for its submitter again
The waiting page has one button: the metadata form autosaves after a pause in
typing, and Julkaise submits it and publishes in the same request, so nothing
is lost without JS.
