# ic-platform-types
The canonical Principal, Account, Subaccount and public identity errors used by
IC Platform. This group owns a literal package version and changelog, independently
of facade/runtime releases, while sharing the same workspace, dependency catalog
and lockfile. Platform re-exports these exact definitions; Wire owns its schema
implementations. The independent series continues from published Types 0.15.0.
The default feature set is empty. Bytes, bounded text and Serde are always
available; `principal-external` adds registry Principal identities/conversions,
and `principal-self-authenticating` selects the unchanged imported derivation with
upstream SHA-224, independently of registry Principal. Enable both when external
conversions are also required.
There is no runtime, executor, Wire or Candid dependency.
Existing Platform consumers keep their import paths. External bytes and account
semantics remain unchanged. Its [group ledger](https://github.com/dragginzgame/ic-platform/blob/main/releases/types/CHANGELOG.md)
owns release notes and links the earlier coordinated history. Initial 0.1 notes
remain historical. Release and publication require explicit RELEASE_GROUP=types.
