ROFL build doesn’t catch missing amd64/Linux image

[ptrus]

I ran into this:

{"level":"info","module":"runtime/global","msg":"Trying to pull docker.io/ptrusr/trustless-x402-facilitator:latest...","ts":"2025-12-05T11:28:40.229691244Z"}
{"level":"info","module":"runtime/global","msg":"Error: choosing an image from manifest list docker://ptrusr/trustless-x402-facilitator:latest: no image found in image index for architecture \"amd64\", variant \"\", OS \"linux\"","ts":"2025-12-05T11:28:40.902055786Z"}

I thought we would catch this during the ROFL build/validation steps, but apparently we don’t. We should detect missing arch/OS entries earlier instead of failing at runtime.

I think we also saw this issue on the BA hackathon.

I haven’t investigated further yet.

We currently check the platform here

cli/cmd/rofl/build/validate.go

Line 291 in fecb52b

if platform.Architecture != "amd64" || platform.OS != "linux" {

. But probably the architecture/os wasn't defined in OCI spec at time of uploading the image.

One way would be that CLI actually tries downloading amd64/linux image and see if it works.
