Fix TinyGo JSONBody[T] type-name collision - #10
Merged
Conversation
TinyGo's generic-function monomorphization keys plugin.JSONBody[T]
instantiations by T's bare type name rather than its full declaration
site. createHello and updateHello each declared their own
`type body struct{...}` with the same name but different fields --
TinyGo could collapse them into one shared field layout, so
json.Unmarshal would silently decode one call site against the wrong
struct.
Renamed both to createHelloBody / updateHelloBody.
Part of a coordinated fix across all first-party plugins; see
Paca-AI/paca#445 and Paca-AI/paca-plugin-github#24 for the full
root-cause writeup and verification.

Summary
Part of the fix for Paca-AI/paca#445 — see Paca-AI/paca-plugin-github#24 for the full root-cause writeup (TinyGo generic-function monomorphization silently collapsing same-named-but-different-shape local types passed to
plugin.JSONBody[T]).createHelloandupdateHelloinbackend/plugin.goeach declared their own locally-scopedtype body struct{...}with the same name but different fields. Under TinyGo this risksjson.Unmarshalsilently decoding one call site against the wrong struct's field layout.Since this is the reference/example plugin other authors copy from, getting this pattern right here matters beyond just this repo.
