What experimental means

The contract can change between protocol families. Tools reject unsupportedtarget_protocol values instead of guessing. Experimental status does not imply that package content is trusted or executable.

Pin reproducible use

npx --yes @seedspec/cli@0.4.2 validate ./my-package
npx --yes @seedspec/cli@0.4.2 inspect ./my-package

Moving from 0.3 to 0.4

Protocol 0.4 is a structural reset around SPEC.md. It does not include a compatibility parser or automatic migration. Reauthor 0.3 packages against the 0.4 structure and validate the result.
