Type aliases
Opaque string types the rest of the API references. Kept as aliases (rather than distinct wrapper types) so consumers can treat them as plain strings; the alias name signals intent.
ItemKey
type ItemKey = string;
Opaque, stable item identifier. Treat as a string token.
ItemPath
type ItemPath = string;
Tree path string (e.g. /1/2/3 or ./X). Display coordinate only.
IsoTimestamp
type IsoTimestamp = string;
ISO-8601 / RFC 3339 date-time string.
