One file of recipes/uploads, at commit 9a5bb24.

// gallery/Export: a signed-in page asks for a CSV of its pictures, and the module makes the file
// itself through the keeper's trusted path. No type rule, no cap, no accept: the module is the
// application.

	call: async (args: { ids?: string[] }, context: { user: string | null }) => {

		for (const id of args.ids ?? []) {
			const record = await imports.Files.get(id);
