erasure coding stewardship endpoint returns false

[istae]

for erasure encoded data during upload (we tried level 3), the stewardship endpoint returns isRetrievable=false.
The endpoint returns true, however, for the same upload without erasure coding.

Another experiment I did was upload a random file, split all the chunk references with the split cmd, and for no erasure coded uploads, all of the chunks were retrievable, but for erasure coded uploads, some chunks were missing (a tiny percentage).

the issue is that if you split the refs yourself after uploading the file, there will be some chunks missing that you cant even query using /chunks

looking at the logs specifically for chunks we cannot retrieve, the node did not even pushsync them 😳

so it's not a retrieval issue but more like an issue with syncing chunks that come from a file with erasure coding
