 - Method registry verification tooling and maintenance docs.
 - Runnable examples for raw REST, search, photo info, OAuth, upload, replace, async tickets, mock transport, and custom cache usage.
 - Release readiness and repository metadata documentation.
+- Full registry and service-wrapper coverage for 224 official Flickr REST API methods.
+- OAuth 1.0a authentication, token storage, raw REST calls, upload, replace, and async ticket polling workflows.
+- DTO-first helpers for high-value photo, people, photoset, upload, replace, and response workflows.
+- Optional public GET caching through package cache contracts and PSR-16 adapter support.
+- Lazy `photos()->searchPages()` pagination helper.
+- AI contributor workflow, CI/CD, secret-handling, method-registry, and repository metadata docs.
 
 ### Changed
 
 - Composer lint scripts now run php-cs-fixer alongside Pint, PHPCS, PHPStan, and PHPMD.
 - Documentation index and root README now better describe SDK identity, testing, release readiness, and non-Laravel scope.
+- Cache metadata is conservative for auth, OAuth, upload ticket, authenticated, permissioned, and mutation methods.
+- Upload and replace multipart requests now close file stream handles after transport requests complete.
+- Test coverage was raised above the 95% statement coverage release target.
 
 ### Security
 
 - Examples read credentials from environment variables and avoid embedded secrets.
+- Normal test and CI paths keep real Flickr API calls opt-in behind `FLICKR_REAL_TESTS=true`.
