Summary
Split the monolithic FilesystemBackend into two specialized backends: a sandboxed core backend and a /tmp-sandboxed DMZ backend for fallback operations.
Changes
process.cwd()withvirtualMode: true/tmpwithvirtualMode: falseas fallback backendRationale
Separates concerns between the agent's sandboxed workspace (core, rooted at
process.cwd()) and a restricted fallback backend (DMZ, rooted at/tmp). The context directory is handled separately via the contextBackend route. This provides clear security boundaries — neither backend has unrestricted root access.Files Changed
