Zero dependencies, exit-code contract

The lint CLI

Kills the whole class crashtest filed upstream (#16: scaffolded manifests pointing at entries that don't exist) at author time, in any fleet repo, with one command.

# human, exit 0 clean / 1 violations / 2 usage
npx packstruct lint packs/

# machine-readable: {schema, packsChecked, violations}
npx packstruct lint packs/ --json

# what the linter validates (SPEC v1, nothing more):
.   schemaVersion === 1
.   kebab-case name that matches its directory
.   dotted MAJOR.MINOR[.PATCH] version, non-empty description
.   relative entry path that physically exists (the #16 class)
.   armedByKey, when present, a non-empty string

Try it now, in the browser

Island below runs the same SPEC v1 rules entirely client-side - your manifest never leaves the tab. It validates the JSON shape only (the CLI additionally checks that the entry file actually ships on disk, the part browsers can't see).
