Phase 2 — internal/storage/: Content-addressed blob storage with atomic writes via rename. BlobWriter stages data in uploads dir with running SHA-256 hash, commits by verifying digest then renaming to layers/sha256/<prefix>/<hex>. Reader provides Open, Stat, Delete, Exists with digest validation. Phase 3 — internal/auth/ + internal/server/: MCIAS client with Login and ValidateToken, 30s SHA-256-keyed cache with lazy eviction and injectable clock for testing. TLS 1.3 minimum with optional custom CA cert. Chi router with RequireAuth middleware (Bearer token extraction, WWW-Authenticate header, OCI error format), token endpoint (Basic auth → bearer exchange via MCIAS), and /v2/ version check handler. 52 tests passing (14 storage + 9 auth + 9 server + 20 existing).
