// Package syncbase defines the wire API for a structured store that supports
// peer-to-peer synchronization.
//
// TODO(sadovsky): Write a detailed package description, or provide a reference
// to the Syncbase documentation.
//
// Security notes:
// The Syncbase service uses permissions tags from v23/security/access.Tag,
// restricted on each hierarchy level to tags used at that level:
// - Valid Service permissions tags are all v23/security/access.Tag tags.
// - Valid Database permissions tags are Admin, Read, Write, Resolve.
// - Valid Collection permissions tags are Admin, Read, Write.
// - Valid Syncgroup permissions tags are Admin, Read.
// Other tags are not allowed and are reserved for future use.
// Unless stated otherwise, each permissions tag requirement on a method also
// implies requiring Resolve on all levels of hierarchy up to, but excluding,
// the level requiring the tag.
// ErrNoAccess, Err[No]Exist, ErrUnknownBatch are only returned if the caller
// is allowed to call Exists on the receiver of the RPC (or the first missing
// component of the hierarchy to the receiver); otherwise, the returned error
// is ErrNoExistOrNoAccess.
