@@ -11,6 +11,7 @@ This package owns the shared browser renderer contract:
 - `EveBrowserProviderHost` owns advertisement-backed surface selection and uses one provider-neutral embedded-document resolver; provider schema dispatch stays behind the host transport boundary.
 - Editable string, textarea, number, select, and choice controls use named Eve state bindings. The renderer preserves edited drafts by provider/surface/binding identity; untouched controls contribute their authored value when an operation captures those bindings atomically under `payload.bindings`.
 - `gamecult.eve.command_result.v1` carries the persisted receipt, an optional one-time Eve projection, a binding-clear directive, and at most one plugin-scoped payload. Only the matching plugin adapter may consume that payload. The renderer-owned receipt region survives the authoritative surface refresh that follows the command.
+- `resource.download` lowers a provider-issued resource grant to an accessible download link. The reference browser accepts only same-origin HTTP(S) or root-relative URLs and sanitizes the suggested filename; the provider remains responsible for authorization, expiry, single-use semantics, and resource bytes.
 
 Host applications own transport and command delivery. Providers own command acceptance and receipts through their advertisements. For example, Eir resolves surfaces through Odin/CultMesh and posts commands to `/eir/command`; Aetheria resolves surfaces through Electron IPC. Neither host should duplicate DOM lowering or import provider internals to find a command route.
