CREDO23 21509e7eca refactor(agents): group filesystem backends under filesystem/backends/ ... The concrete filesystem backends are consumed only by the MAC filesystem layer (tools, path-resolution middleware, the resolver, skills backend) and tests -- no external app code. Group them next to the filesystem middleware they serve: - filesystem_backends.py -> filesystem/backends/resolver.py - middleware/kb_postgres_backend.py -> filesystem/backends/kb_postgres.py - middleware/local_folder_backend.py -> filesystem/backends/local_folder.py - middleware/multi_root_local_folder_backend.py -> .../multi_root_local_folder.py - document_xml.py -> filesystem/backends/document_xml.py Repoint all 21 importers. No behavior change; import-all + filesystem backend/path-resolution/knowledge-search unit tests stay green (478).		2026-06-05 11:02:26 +02:00
