- limits:
  - write-gated (binding): write accepted but the read-back is signed probe:https://pan.ios98.com/api/fs/put
- interface detail: rest
- composes with: a fetch substrate: point a cache and two mirrors at it, never a write tier
- reliability: The read-gated write. PUT returns code 200 with message success, and GET /p/ then returns 51 bytes of code 401 expire missing: the instance signs its raw path and a guest cannot mint the signature. Provider 139Yun. The bytes went in and cannot come out.
