One successful claimant
A burn share atomically removes public reachability when the first access lease wins. The winner receives a short window to read the file while cleanup is scheduled.
Constraints
- Burn files cannot be members of a multi-file transfer.
- The opening limit is fixed to one.
- A PIN can still be used.
- A reusable public storage URL is never issued.
Use with care
Note: Link-preview bots, security scanners, or the wrong recipient can consume a poorly protected one-time link. Add a PIN for sensitive deliveries.
