A `download_links` row is a capability URL for one download: anyone holding the unguessable token
|
||
|
|
can watch the file on the public `/watch/{token}` player page — no account needed. Optional
|
||
|
|
per-link controls: an expiry, an "allow download" toggle, and an (argon2-hashed) password. Revoke
|
||
|
|
= delete the row. Distinct from `download_shares` (an ACL grant to another *registered* user).
