- db.Open: delegate to mcdsl/db.Open
- db.Migrate: rewrite migrations as mcdsl/db.Migration SQL strings,
delegate to mcdsl/db.Migrate; keep SchemaVersion via mcdsl
- auth: thin shim wrapping mcdsl/auth.Authenticator, keeps Claims
type (with Subject, AccountType, Roles) for policy engine compat;
delete cache.go (handled by mcdsl/auth); add ErrForbidden
- config: embed mcdsl/config.Base for standard sections (Server with
Duration fields, Database, MCIAS, Log); keep StorageConfig and
WebConfig as MCR-specific; use mcdsl/config.Load[T] + Validator
- WriteTimeout now defaults to 30s (mcdsl default, was 0)
- All existing tests pass (auth tests rewritten for new shim API,
cache expiry test removed — caching tested in mcdsl)
- Net -464 lines

Proto definitions for 4 services (RegistryService, PolicyService,
AuditService, AdminService) with hand-written Go stubs using JSON
codec until protobuf tooling is available.
Interceptor chain: logging (method, peer IP, duration, never logs
auth metadata) → auth (bearer token via MCIAS, Health bypasses) →
admin (role check for GC, policy, delete, audit RPCs).
All RPCs share business logic with REST handlers via internal/db
and internal/gc packages. TLS 1.3 minimum on gRPC listener.

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).
