+### Added
+- Discovery lives in its own package, [`pollora/discovery`](https://github.com/Pollora/discovery), which the framework requires: the engine, its contracts, `DiscoveryManager`, the cache and the `#[SkipDiscovery]` attribute, with their tests and benchmarks. Class names do not change. The framework keeps what needs Laravel: the service provider, `discovery:run` / `discovery:clear`, `DiscoveryRegistrar`, `ServiceProviderDiscovery`, the Laravel adapters, and `HasConfiguringSupport`, which builds post types and taxonomies
+- Discovery can run without Laravel's application, the first step towards `pollora/discovery`: `new DiscoveryEngine()` works with no argument. Two contracts let an environment plug in — `InstanceResolverInterface` builds the classes discovery needs (Laravel's container in a Pollora application, `ReflectionInstanceResolver` otherwise) and `DiscoveryRegistrarInterface` adds the environment's discoveries before each run (`DiscoveryRegistrar` keeps scanning the container's `*Discovery` bindings). `Psr16DiscoverCacheDriver` caches scans in any PSR-16 cache
+
+### Changed
+- `DiscoveryEngine`, `DiscoveryCacheManager`, `InstancePool` and `ReflectionCache` take their dependencies instead of reaching for `app()` and `config()`; reading `structure-discoverer.cache` moved to `LaravelDiscoveryCacheManagerFactory`. `DiscoveryRegistrar::registerFromContainer()` is now `registerInto()`. These are infrastructure classes, outside the public contracts (`Pollora\Discovery\Domain\*`), which do not change
+- One `DiscoveryCacheManager` is shared by the engine and the `pollora:doctor` discovery cache check, which built its own
+- The discovery benchmarks measure memory as PHP allocates it, from a reset peak: they read 2 MB whatever the load
+
+### Deprecated
+- `DiscoveryCacheInterface` and `LaravelDiscoveryCache`, removed in 15.0: nothing reads this cache, scans are cached by the Spatie driver given to `DiscoveryCacheManager`
