_managed_files owns the file snapshot reader and public metadata helpers used by pinned directories, durable copies, and opaque snapshots; transaction staging owns read_target and same_identity_and_contents; dead helpers removed; hook_template no longer re-exports the guard generator; mypy targets win32 so _windows_security type-checks.

_client_common.py owns request building and EOR signing for both clients; types follow the Backend contract; the deprecated issue_token alias and token response aliases are removed; crypto, utils, and CLI comments trimmed.
