+official x86_64 helper in a disposable user/network namespace. A veth pair
+provided only documentation-range private addresses and there was no default
+route. A private Decky module stub supplied task-owned settings, runtime,
+plugin and log directories; its notification socket was moved into that
+directory. The backend's `start_backend`, `proxy_get` info request and
+`proxy_post` prepare/upload methods passed. One 42-byte public marker
+arrived in the private upload directory with independent SHA-256

+transfer, an installed Frame plugin or real-network transfer.

 A [DeckyFileServer ARM64 follow-up](evidence/framey-fileserver-arm64-2026-10-27.md) ships an offline, digest-checked GPL helper build, corresponding vendored source and a build recipe. Only its exact managed archive can replace the x86 helper and remove its unnecessary root flag. Actual Decky 3.3.0 discovery/RPC and real Frame HTTPS private-fixture listing/download pass; uploads stay disabled. Hostname-DNS failures and empty optional arguments are repaired. Decky 3.3.0 still exposes `decky.HOME`; that call is unchanged. The plugin moves from broken to partial: its frontend advertises HTTP/steamdeck URLs and needs a Steam folder picker. Use HTTPS and a preconfigured directory. Uploads, generated thumbnails and worn VR remain unverified.
