Install
From inside FreeSDN, open Plugins › Marketplace, sync the catalogue, and install Hello World. The instance verifies the catalogue signature before ingest and the archive checksum before unpacking.
To install the archive directly instead:
curl -fSLO https://registry.freesdn.org/dl/hello-world-1.1.0.zip sha256sum hello-world-1.1.0.zip # expect: b19c53bd9df6c2b08cc8cbae5110286097b3cb8c98dab1380846c8206522e555
Then upload the ZIP under Plugins › Install from file.
Plugins run in-process with the API. The loader applies import hygiene, ZIP-slip and ZIP-bomb guards, hash-pinned dependencies and per-action permission caps, but it is a cooperative trusted-author model and not a security sandbox. Install what you would be willing to run as application code.
