Research direction

Start by reading the referenced wit/keyvalue/wit/cas.wit definition and comparing the version conventions used by wasi-otel and wasi-webgpu. Determine how the keyvalue API should build on WASI 0.3.0, including the async interface and CAS behavior. Done means the proposal is updated to the agreed 0.3.0-rc.n version with those API changes documented in the WIT definition.

Written by the indexing model from the issue text.

Description

Now that WASI 0.3.0 has been released, this proposal should build on WASI 0.3.0. I recommend setting the version to 0.3.0-rc.n as well like wasi-otel and wasi-webgpu.

I created an async keyvalue API (asyncified version of this wit definition) that additionally solves the ABA problem for CAS. This may be a good starting point: https://github.com/wasmCloud/wasmCloud/blob/main/wit/keyvalue/wit/cas.wit
