From 5b75d633aa9845cd57071b5ffdd6a79366ceaca4 Mon Sep 17 00:00:00 2001 From: YueGuobin Date: Fri, 8 May 2026 22:52:17 +0800 Subject: [PATCH 1/5] feat: Add API endpoint to list node files Implement issue #2719 - Add API endpoint to list project files - Add GET /v3/projects/{project_id}/nodes/{node_id}/files endpoint - Add list_node_files() method to Project class - Add security checks to prevent path traversal - Filter out .ghost temporary files - Return file paths with MD5 checksums - Require Node.Audit privilege This allows users to discover dynamically created files such as QEMU disk images created via the disk image API.
