## [Unreleased]

### Added

- `policies_to_pst(policies)` parses Cedar policy text into typed `cedarpy.pst` nodes (frozen dataclasses, one per `cedar_policy::pst` node kind), matching a real Cedar structure a consumer can pattern-match on instead of an untyped tree keyed by string operators. Static policies and unlinked templates only; a partial-evaluation residual from `is_authorized_partial` cannot be represented this way, because PST's own policy type rejects any clause containing an unresolved `unknown(...)` node ([#107](https://github.com/k9securityio/cedar-py/issues/107)). Requires cedar-policy 4.11.0+, bundled by [#106](https://github.com/k9securityio/cedar-py/pull/106).
- `tpe_authorize(principal, action, resource, policies, entities, schema, context=None, verbose=False)` performs type-aware partial evaluation (TPE) on a request whose principal and/or resource identity is unknown. Separate entry point from `is_authorized_partial`, which it does not call or change. TPE's residuals are typed `cedarpy.pst.Template` nodes, unlike `is_authorized_partial`'s. `permits`/`forbids` stay separate, each a `TpeClassification` of residual/true/false/error policy ids. Enables the `tpe` Cargo feature; adds no dependencies, checked against the resolved lockfile.
