Release v0.17.0

Added

• Add source-neutral artifact, member, type-use, binding, and identifier-role facts with fixed-snapshot derivation lineage. (#19)
• Add exact nested .NET type-use fact emission for independently composed adapters. (#19)

Changed

• Resolve exact member bindings by complete artifact key and fail closed on conflicting, malformed, or unrepresentable evidence while preserving existing aggregate and legacy adapter APIs. (#19)
