 - Memory/search: share memory embedding provider registrations across split plugin runtimes so memory search no longer fails with unknown provider errors after memory-core registers built-in adapters. (#55945) Thanks @glitch418x.
 - Discord/Carbon beta: update `@buape/carbon` to the latest beta and pass the new `RateLimitError` request argument so Discord stays compatible with the upstream beta constructor change. (#55980) Thanks @ngutman.
 - Plugins/inbound claims: pass full inbound attachment arrays through `inbound_claim` hook metadata while keeping the legacy singular media attachment fields for compatibility. (#55452) Thanks @huntharo.
+- Plugins/Matrix: preserve sender filenames for inbound media by forwarding `originalFilename` to `saveMediaBuffer`. (#55692) thanks @esrehmki.
