Implement a product-owned Rust state-kernel executable for the existing schemaVersion 1 read-file and read-file-if-present operations. Preserve exact root marker, private ownership, directory/leaf identities, synchronous bounded responses, and definitely-orphaned quarantine maintenance currently performed during reads.
Keep TypeScript production routing and all existing write/CAS owners unchanged until independent parity review, native macOS/Linux qualification, immutable binary/package provenance, source-closure admission and current Required CI pass. No provider/auth/data migration is included.
Qualification uses synthetic isolated roots and adversarial filesystem/child schedules; reads are explicitly maintenance-capable. Windows, remaining state operations, default routing and the CLI five-asset distribution change remain separately named activation gates. A fixture-only executable is an implementation increment, not completion of the production migration.
