The per-session record store is now the ONLY cwd mechanism. Deleted: - env.cwd_owner stamping + prev_owner threading (terminal_tool): the shared env no longer carries ownership metadata at all - _resolve_command_cwd's env/prev_owner params: resolution is workdir > session record > config/override default - file_tools._live_cwd_if_owned + _get_live_tracking_cwd: path resolution never consults the shared env's live cwd - file_tools._last_known_cwd + _remember_last_known_cwd + _last_known_cwd_for: the #26211 preserved-anchor registry is subsumed by the session record, which never lived on the env and therefore cannot be lost to env cleanup. The _get_file_ops stale-cache rescue now writes the record instead. - env recreation (both _get_file_ops and terminal_tool) seeds the fresh env from override > session record > config Why no transition fallback: the legacy state was process-local and in-memory exactly like the record store — after a restart both start empty, and within a running process every legacy write site has been dual-writing the record since step 1. There is no populated-legacy/ empty-record state to fall back for. Tests updated to drive the record store instead of the deleted mechanism; the cross-session isolation suite now asserts the same behavior contracts (no leak, cd isolation, #26211 persistence) against the new architecture, plus a new "session C inherits nothing" case that the old ownership guard could not express.

"""Regression tests for profile-aware tilde expansion in file tools.
|
|
|
|
The bug (#48552): in-process file tools (write_file, read_file, patch,
|
|
search_files) resolved ``~`` via ``os.path.expanduser()``, which reads the
|
|
gateway process's ``HOME``. In profile mode (Docker, systemd, s6) the gateway
|
|
``HOME`` differs from the profile ``HOME`` that interactive sessions use, so
|
|
``~`` expanded to the wrong directory and file operations failed with
|
|
"no such file or directory".
|
|
|
|
The fix adds ``_expand_tilde()`` which delegates to
|
|
``hermes_constants.get_subprocess_home()`` — the same policy the terminal tool
|
|
uses for subprocess environments.
|
|
|
|
