This is a PLC[1] mirror running Allegedly[2] in mirror mode. Allegedly synchronizes and proxies to a downstream PLC reference server instance[3] (why?[4]).

Configured upstream:
29
+
30
+
{upstream}
31
+
32
+
33
+
Available APIs:
34
+
35
+
- All PLC GET requests [5].
36
+
- Rejects POSTs. This is a mirror.
37
+
38

try `GET /{{did}}` to resolve an identity
