Phase 00: Skeleton

Status: Planned

Deliverables

1. package3/kotlin/go.mod — new Go module github.com/mochilang/mochi/package3/kotlin.
2. package3/kotlin/errors/errors.go — bridge-specific error types: ErrUnsupportedMetadataVersion, ErrArtifactNotFound, ErrNativeImageBuildFailed, ErrCapabilityViolation, ErrGraalVMNotFound, ErrLockMismatch.
3. package3/kotlin/semver/ — Maven version range parser: PVP/Semver/Maven range syntax ([1.0,2.0), 1.7.+, LATEST).
4. package3/kotlin/maven/coord.go — Maven coordinate parser: ParseCoordinate("org.example:[email protected]") → {GroupID, ArtifactID, Version, Classifier}.
5. package3/kotlin/README.md — component overview.

Gate

go test ./...

All packages compile cleanly. The semver parser handles the following inputs:

Input	Result
"1.7.3"	Exact version 1.7.3
"[1.0,2.0)"	>=1.0 <2.0
"[1.0,)"	>=1.0
"(,2.0]"	<=2.0
"1.7.+"	>=1.7.0 <1.8.0
"LATEST"	Latest available (resolve at fetch time)
"RELEASE"	Latest release (non-SNAPSHOT)

The Maven coordinate parser accepts:

Input	Result
"org.example:mylib"	{GroupID: "org.example", ArtifactID: "mylib"}
"org.example:[email protected]"	{..., Version: "1.0.0"}
"org.example:[email protected]@jdk8"	{..., Version: "1.0.0", Classifier: "jdk8"}
"invalid"	ErrInvalidCoordinate
