"""Group access to the observation store — regression coverage for issue #54.

|
|
Two defects: (1) a non-group user's stat() on the store directory raised
|
|
PermissionError straight through open_store_readonly(), crashing status/TUI
|
|
instead of degrading to the Store fault view; (2) even group members could
|
|
not open the WAL-mode store because root-created sidecars lacked group write
|
|
and the store directory lacked group execute-then-write.
