// Append-only Cap'n Proto storage + redb indices
//
// capnp logs are the source of truth:
//   nodes.capnp     - ContentNode messages
//   relations.capnp - Relation messages
//
// redb provides indexed access; Store struct holds in-memory state.
//
// Module layout:
//   types.rs — Node, Relation, enums, capnp macros, path helpers
//   index.rs — redb index operations
//   capnp.rs — capnp log IO (load, replay, append, fsck)
//   ops.rs   — mutations (upsert, delete, rename, etc.)
//   view.rs  — StoreView trait for read-only access
